So few years after it's released, Windows Phone will finally end it's life.
It's time to update Win10 Mobile Offline Update Package to V5.2 (still beta5), then a next step - Semi-Offline Update Package V5.3 beta 6, or "WXM-SOUP".

I'm not going to fix the bug of Windows 10 Mobile Offline Update V5.3b6 now.
This project will not update again and placed there, and no technical issue will be answered. I've stopped using Windows Phone and shifted to HMD Nokia developement since 2017.

告中国用户:严禁转载本教程到智机网!


- I merged every packages that need to be pushed into one.
- I created a tool to allow us analyze the phone, target packages and push them.
- Because of that, you will not encounter keyboard issue like before, but we still recommend you to remove lockscreen password before you proceed.

Just a little warning:
I've noticed someone in China is reselling this package to others for a pretty unreasonable price. To prevent this happen in V5.2 release, we added server-side checksum verification.
You can still use it even you don't have Internet connection or my server down in the future.

Win10 Offline Update Package Project is never meant for sale - if you bought this from someone, you've been scammed and you must request refund or report the seller who sold you this.

Chinese translation of the warning above:

最近,我注意到在中国,有人正在以非常不合理的价格出售Win10 Mobile离线更新包项目。为了防止这个事情在本次版本发生,我们添加了服务端校验检查,以确保工具确实是我们提供的正确版本。
即便没有网络连接或者未来服务器宕机,你也可以使用,但是我们无法保证文件的正确性。

Win10 Mobile离线更新包项目不可转卖——如果你从他人手中购买了这份更新包,你应当立即申请退款或者是向平台举报卖家。

Known unsupported Models:

All 4GB ROM models, e.g: Nokia Lumia 530, HTC 8S, Huawei Ascend W1, Hisense E260T+, K-Touch E8
HTC 8X
Cancelled 5th Generation Lumia prototypes, e.g. Honjo
RX-130 (Hapanero)

Then you tell me.


How to use?
Video demonstration: https://www.youtube.com/watch?v=g2pCzz5_znY

1. The OS Version of your phone must be at least 8.10.14219.341. If it's older than 8.10.14219.341, update it before you use the package. Most of phones should be able to search updates.
Samsung ATIV S and ATIV SE users can download required packages from "WP8.1_Offline_Specific_Models.txt" in attachment below.

2. Download Win10 Mobile Semi-Offline Update Package V5.3 beta 6 from the attachment (HCTSW_WXMSOUP_V5.3beta6.update.lzma2.7z) below.
Existing beta 2 to beta 5 owners can also download it and overwrite all the files.

What's new in V5.3 beta 6?
- Download amounts reduced as much as possible.
- Now it will download necessary packages from Microsoft server automatically.
- Allow end-users to provide detailed error reports if error appears.

What's new in Beta 5?
- Replace buggy timestamp acquiring method.
To use this new method, your PC must have PowerShell enabled, which I think Windows 7 or newer OS should have that enabled by default.
This will also make the tool usable in 2020.

If no more bugs, this will become into the final version.

What's new in Beta 4?
- Add Simplified Chinese translation of main executable (win10oup_cn.exe) .
- Ignore the "MMOSLOADER" file to prevent the executable itself.
- Change the logic of judging if WDRT installed.
- Fix the FC issue of beta 3.
- Now it can be used if the path contains space.
- Administrator previleges no longer required.

3. You must have WDRT and required all the Microsoft Visual C++ Redistributable Runtimes installed, otherwise it will not run as expect. All Visual C++ Redistributable Runtimes can be downloaded here:
https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/

4. Extract the package and open "run_en.cmd" (Simplified Chinese users can run "run_cn.cmd" instead).

5. Follow the procedure the wxmsoup told you.

6. A "Device and Printers" window will appear. Disconnect (if connected) and remove your phone inside of it.

7. Get back to win10oup, press any key, and connect your phone to PC. Wait 10 seconds then press enter to detect your phone by using getdulogs.

8. If you see your phone listed, input "yes" (without quotes, lower case) and press enter. Input others will let getdulogs detect again, in case it's not listed.

9. Getdulogs will now grab the log and analyze it, after analyze complete, it will copy packages from repo directory to pkgs directory automatically. You may see few "System cannot find the file specified" prompts which expected (usually MMOS related). It can be still done even if your battery capacity is lower than 40%, but we still recommend you to fully recharge the battery.

10. Wait for the procedure complete, you may need to wait up to 40 minutes to get to Windows 10 Mobile 10586.107.

11. After 10586.107 installed, you can now use Interop Tools to hack the model to get further updates. Registry files are placed at "regs" directory, and Interop Tools 1.9.400 (known working version) can be downloaded from:
https://forum.xda-developers.com/showpost.php?p=70457420&postcount=550

12. The packages that pushed to your phone is located at "pkgs" directory - you can push it manually when you flash your phone back to WP8.1 and want to update to W10M next time.

Following Content is now archived to users who still want to use old packages themselves.




Recently, Microsoft released Over-the-Cable Updater for Windows Phone. However, it still can't update unsupported devices to W10M directly, for supported devices they will start from 10586.107 first. Continue to use my offline update package.

But OTC Updater can be used as your alternative choice for further update, after you modified the model.

PLEASE DOWNLOAD V4.1 instead of V3/V4. V4.1 added support for LG Lancet and any other devices that has Snapdragon 410 Processor and fixed issues for several Snapdragon 800 Devices - Especially Nokia Lumia 1520 and Samsung ATIV SE.

To Lumia 810 Users: Now you can update to WP8.1GDR1 with Offline Update Packages. I knew how painful update to WP8.1 GDR1 on Lumia 810.
Push these packages from PART1 to PART4.

Is there any Huawei Ascend W2 users want a full offline update package to WP8.1 GDR1?

In August 2016, I released Win10 Mobile Offline Update Package for old models that can't get to Windows 10 right now in several communities in China.
Today, I'd like to present this package to everyone in XDA.

- Models with * are supported by Upgrade Advisor, these models are NOT RECOMMENDED to use this offline update package.

Need feedbacks from these models:
- Samsung ATIV S (SGH-T899M)
- Samsung ATIV S Neo (SGH-I187)
- Samsung ATIV Odyssey (SCH-I930)
- HTC One M8 for Windows (T-Mobile, 0P6B140)

To do that, you must be familiar with how to roll back your phone to Windows Phone 8.1. Windows Device Recovery Tool is necessary.

Instruction:
1. Make backup for your phone, for example, copy data to your PC. And make sure the OS of your PC must be at least Windows 7 Service Pack 1. Windows 8/8.1/10 are also acceptable, but you must install every Visual C++ Redistributable Runtime and Windows Device Recovery Tool.
2. Check your OS version in about phone. The OS version must be at least 8.10.14219.341 or newer. If the version is lower than required, please update it. You may want to use Windows Insider app from Windows Store. REMOVE YOUR PIN LOCK to prevent from some unknown issues after an upgrade.
3. Download and open the package by 7-Zip. Choose your model and extract the exact folder from it. For example, Nokia Lumia 820 should extract 480x800 folder from 2nd Generation folder. DO NOT EXTRACT cabs in that folder.
4. Press Win(Command)+R, in run command dialog, type "control printers" and run. Unplug your phone and remove your phone in Device and Printers window.
5. Extract iutool package attached below, and open a command prompt window with Administrator privilege. Change working directory to iutool.exe's location.
6. Plug your phone to your PC, then type this command:
iutool -l
7. If your phone is shown in command prompt window, then type this command:
iutool -V -p D:\480x800
(For example I have extracted this folder in Drive D)
8. Wait for about 40 minutes, then your phone will be in Win10 Mobile 10586.107.
9. Open Developer mode in "For Developers" option, then deploy tools that could modify phone's model to your phone.
10. Use any method that you know to modify your model, for example, I modified model to Microsoft RM-1116 (Lumia 950 XL Dual SIM). If you are going to use VCreg or Interop Tools, you needn't to Restore NDTKSvc.


11. Check update, and you will receive another update to Win10 Mobile 14393 or later stable builds. Update to this build will fix critical issues you met.
12. After the update to another build, I recommended you to perform a hard reset to your phone. That would make the phone works at the best state.

Here's the demostration of upgrade Nokia Lumia 1020 (Hong Kong Variant) to W10M 10586.107:

Known issues:
- If the pre-installed default IME doesn't include English (United States), after an upgrade by this offline update package, pre-installed IME won't work. Please make sure your firmware's pre-installed IME included English (United States). However, if you modify your model by using Interop Tools by gus33000 then perform another update, IME issue will be fixed. Because this update package is made for Chinese users and China variant firmware at first, I couldn't take care of every variants. Sorry for that.
- To HTC 8X/8XT users: I'm sorry for the promise I made, but the packages doesn't work on HTC 8X/8XT because the MainOS partition is too small to upgrade. That's HTC's mistake.
- To Nokia Lumia 638 users: Please flash the latest China Variant Firmware (India Variant is not as stable as China Variant) to make sure the phone works at the best state, then download Upgrade Advisor from Windows Store to upgrade.
- To Prototype model users especially the cancelled model: Please make a full backup of phone first by using WinHex or something else. If you didn't do that, unbrick the prototype model is almost impossible.
- Because phones with 4GB ROM aren't capable for these package such as Nokia Lumia 530 and HTC 8S, this update package is not suitable for these models.
- To Nokia Lumia 1020 users: Update to Windows 10 Mobile will reduce the performance of precious 41MP Camera. If your Nokia Lumia 1020 is used for photography, DO NOT UPGRADE.
- Glance screen feature will be lost after another update to 14393 or later build, but it's possible to fix by using Interop Tools by gus33000.
- To Samsung ATIV S (GT-I8750) and ATIV SE users: Offline Update Packages to WP8.1GDR1 or GDR2 is available now. Now you can update to WP8.1GDR1 or GDR2 without using SDK Deployment.
- To Samsung ATIV S (GT-I8750) users: make sure you are using XXDOC2 firmware before update.

If your phone's pre-installed keyboard is neither English (United States) nor Chinese (Simplified, PRC), you'll meet a problem that your default keyboard doesn't work. To fix it:
1. Download the Internal IME Fix Package from the link below.
2. Extract your keyboard layout with your language code, for example, if you are using English (United Kingdom), extract the cab with en-gb from that package to the root of drive D, and rename it to 123.cab.
3. Open a command prompt window with administrator previlege, and change working directory to where iutool is, type this command:
iutool -l
4. Make sure your phone is listed in the output. Then type this command:
iutool -V -p D:\123.cab
5. You will encounter an error with code 8024a110, do not panic, the phone is still working with that package. The phone will reboot soon and perform another update to fix your keyboard.
6. After the update, you're able to use your keyboard. Modify phone model with VCreg or Interop Tools, and search for another update, remaining keyboard layout and pre-installed speech package will be fixed along with that update.
Here's some of the possible used language code in case you don't know how to choose:
de-de: German
en-au: English (Australia)
en-ca: English (Canada)
en-gb: English (United Kingdom)
en-ie: English (Ireland)
en-in: English (India)
fr-ca: French (Canada)
fr-fr: French (France)
ja-jp: Japanese
ko-kr: Korean
zh-hk: Chinese (Traditional, Hong Kong)
zh-tw: Chinese (Traditional, Taiwan)

You can also enable Mobile Enterprise on your phone. Just extract MobileEnterprise.ppkg from Enterprise_Configuration_File_for_TH2_Builds folder, and copy it to your phone, then tap "Yes, add it" on your phone. Soon your phone will become into Windows 10 Mobile Enterprise. Reboot your phone, Settings - Phone Update, Advanced options, and there's a "Defer Upgrade" available, now check it, then search update. If you still can't get any update, please modify your model and search update again.
Thanks for the collection here: http://forum.xda-developers.com/win...m-builds-update-links-collection-cab-t3234805 , and now it's possible to upgrade old models without Unlock Bootloader and Interop Unlock with SD card and WP8 SDK.
P.S. Only V4 and V3 set available here. V1 and V2 are deprecated and archived in Chinese Community.

Little hints:
- If your Lumia 830's navigation keys aren't responsible, you can push packages for Lumia 73X or Lumia 640/XL.
- If your Lumia 1520's navigation keys aren't responsible, you can push packages for McLaren.
- The directory catagory is depended on resolution, SoC, Virtual Navigation Bar availability, stock language packages included in firmware, etc.
- DO NOT USE Interop Tools provided in Windows Store.

In case that I can't give you help in time, here's some troubleshooting info for you:
IUTool Command Error Codes List: https://msdn.microsoft.com/en-us/library/windows/hardware/mt131833(v=vs.85).aspx
Also, if you encounter a error, don't unplug your phone, type command "getdulogs -o 123.cab" and waiting for Device Update Logs output. Open the 123.cab and open ImgUpd.log to get some hints. If you are a developer, you should be sensitive to error code lines.
Or, just attach the 123.cab to here.



Special Thanks:
@gus33000 for his Interop Tools
@zephray for LG Lancet W10M Update Package grabbing
DPMason, Ren, Max for provide devices to grab packages

Deprecated version download counts:
V3: at least 25,406 downloads
V4: at least 10,478 downloads

GNU components used:
- gawk
- wget
- aria2c

This is amazing work, OP, well done!
It's really useful to know that there's a way back from WP8.1 that doesn't involve risky flashing with WP Internals.
You mention that photography is downgraded for 1020, but my 1020 seems to produce good images still on W10M if I use Lumia Camera rather than the Windows Camera app. What's your experience?

When upgraded to 14393.576, Lumia Camera works slower than that in WP8.1. I have two Lumia 1020 with yellow color to make comparison. Also, I'm using Nokia Camera Pro (pre-installed on Cyan), not the upgraded Lumia Camera by Microsoft Mobile.
Another alternative choice is using ProShot (ProShot Classic for W10M 10586.XXX or WP8.1) from Windows Store.
But upgrade 1020 to W10M is still not recommended.

got 1020 updated to 14393.576 (changed to 950 xl and enrolled to preview for developpers)
All is working well, even luminosity toggle (manual-automatic). Glance is back with the reg edting solution.
P.S. if cortana crash on listening try choosing another voice assistent (e.g. Microsoft Elsa Mobile).

Lumia 925

I updated my mobile from 8.1 to windows 10 by using this method, it loaded fine (no errors). Just that when I tried to type anything it wouldn't type. So I couldn't use interop tools to be able to update if from W10M 10586.107. I have managed to downgrade again to 8.1. But I don't know why the keyboard didn't work. I even download different keyboard languages, but they showed as being downloaded but the keyboard still wouldn't work. The keyboard would show up, but that's all.
Any idea's ?

This offline update package only considered keyboard of English (United States) and Simplified Chinese. If your default keyboard is not English (United States), for example English (India), you may need to push another keyboard package by using iutool.
I'll host the internal keyboard fix up package to mega soon.

I have released another package to fix this problem. Plz check it out

I tried to add the keyboard using iutool but got an error command failed (HRESULT = 0x80070002)

update
I fixed my keyboard issue. what I did was I made a folder and named it 123 and put the keyboard cab that I named 123.cab inside. Then on iutool I put iutool -v -p C:\123 (this time I put little v instead off big V) I did get an error but my phone still updated itself and went to the spinning cogs and updated. So thanks for the help and now my mobile is on windows 10.

    So few years after it's released, Windows Phone will finally end it's life.
    It's time to update Win10 Mobile Offline Update Package to V5.2 (still beta5), then a next step - Semi-Offline Update Package V5.3 beta 6, or "WXM-SOUP".

    I'm not going to fix the bug of Windows 10 Mobile Offline Update V5.3b6 now.
    This project will not update again and placed there, and no technical issue will be answered. I've stopped using Windows Phone and shifted to HMD Nokia developement since 2017.

    告中国用户:严禁转载本教程到智机网!


    - I merged every packages that need to be pushed into one.
    - I created a tool to allow us analyze the phone, target packages and push them.
    - Because of that, you will not encounter keyboard issue like before, but we still recommend you to remove lockscreen password before you proceed.

    Just a little warning:
    I've noticed someone in China is reselling this package to others for a pretty unreasonable price. To prevent this happen in V5.2 release, we added server-side checksum verification.
    You can still use it even you don't have Internet connection or my server down in the future.

    Win10 Offline Update Package Project is never meant for sale - if you bought this from someone, you've been scammed and you must request refund or report the seller who sold you this.

    Chinese translation of the warning above:

    最近,我注意到在中国,有人正在以非常不合理的价格出售Win10 Mobile离线更新包项目。为了防止这个事情在本次版本发生,我们添加了服务端校验检查,以确保工具确实是我们提供的正确版本。
    即便没有网络连接或者未来服务器宕机,你也可以使用,但是我们无法保证文件的正确性。

    Win10 Mobile离线更新包项目不可转卖——如果你从他人手中购买了这份更新包,你应当立即申请退款或者是向平台举报卖家。

    Known unsupported Models:

    All 4GB ROM models, e.g: Nokia Lumia 530, HTC 8S, Huawei Ascend W1, Hisense E260T+, K-Touch E8
    HTC 8X
    Cancelled 5th Generation Lumia prototypes, e.g. Honjo
    RX-130 (Hapanero)

    Then you tell me.


    How to use?
    Video demonstration: https://www.youtube.com/watch?v=g2pCzz5_znY

    1. The OS Version of your phone must be at least 8.10.14219.341. If it's older than 8.10.14219.341, update it before you use the package. Most of phones should be able to search updates.
    Samsung ATIV S and ATIV SE users can download required packages from "WP8.1_Offline_Specific_Models.txt" in attachment below.

    2. Download Win10 Mobile Semi-Offline Update Package V5.3 beta 6 from the attachment (HCTSW_WXMSOUP_V5.3beta6.update.lzma2.7z) below.
    Existing beta 2 to beta 5 owners can also download it and overwrite all the files.

    What's new in V5.3 beta 6?
    - Download amounts reduced as much as possible.
    - Now it will download necessary packages from Microsoft server automatically.
    - Allow end-users to provide detailed error reports if error appears.

    What's new in Beta 5?
    - Replace buggy timestamp acquiring method.
    To use this new method, your PC must have PowerShell enabled, which I think Windows 7 or newer OS should have that enabled by default.
    This will also make the tool usable in 2020.

    If no more bugs, this will become into the final version.

    What's new in Beta 4?
    - Add Simplified Chinese translation of main executable (win10oup_cn.exe) .
    - Ignore the "MMOSLOADER" file to prevent the executable itself.
    - Change the logic of judging if WDRT installed.
    - Fix the FC issue of beta 3.
    - Now it can be used if the path contains space.
    - Administrator previleges no longer required.

    3. You must have WDRT and required all the Microsoft Visual C++ Redistributable Runtimes installed, otherwise it will not run as expect. All Visual C++ Redistributable Runtimes can be downloaded here:
    https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/

    4. Extract the package and open "run_en.cmd" (Simplified Chinese users can run "run_cn.cmd" instead).

    5. Follow the procedure the wxmsoup told you.

    6. A "Device and Printers" window will appear. Disconnect (if connected) and remove your phone inside of it.

    7. Get back to win10oup, press any key, and connect your phone to PC. Wait 10 seconds then press enter to detect your phone by using getdulogs.

    8. If you see your phone listed, input "yes" (without quotes, lower case) and press enter. Input others will let getdulogs detect again, in case it's not listed.

    9. Getdulogs will now grab the log and analyze it, after analyze complete, it will copy packages from repo directory to pkgs directory automatically. You may see few "System cannot find the file specified" prompts which expected (usually MMOS related). It can be still done even if your battery capacity is lower than 40%, but we still recommend you to fully recharge the battery.

    10. Wait for the procedure complete, you may need to wait up to 40 minutes to get to Windows 10 Mobile 10586.107.

    11. After 10586.107 installed, you can now use Interop Tools to hack the model to get further updates. Registry files are placed at "regs" directory, and Interop Tools 1.9.400 (known working version) can be downloaded from:
    https://forum.xda-developers.com/showpost.php?p=70457420&postcount=550

    12. The packages that pushed to your phone is located at "pkgs" directory - you can push it manually when you flash your phone back to WP8.1 and want to update to W10M next time.

    Following Content is now archived to users who still want to use old packages themselves.




    Recently, Microsoft released Over-the-Cable Updater for Windows Phone. However, it still can't update unsupported devices to W10M directly, for supported devices they will start from 10586.107 first. Continue to use my offline update package.

    But OTC Updater can be used as your alternative choice for further update, after you modified the model.

    PLEASE DOWNLOAD V4.1 instead of V3/V4. V4.1 added support for LG Lancet and any other devices that has Snapdragon 410 Processor and fixed issues for several Snapdragon 800 Devices - Especially Nokia Lumia 1520 and Samsung ATIV SE.

    To Lumia 810 Users: Now you can update to WP8.1GDR1 with Offline Update Packages. I knew how painful update to WP8.1 GDR1 on Lumia 810.
    Push these packages from PART1 to PART4.

    Is there any Huawei Ascend W2 users want a full offline update package to WP8.1 GDR1?

    In August 2016, I released Win10 Mobile Offline Update Package for old models that can't get to Windows 10 right now in several communities in China.
    Today, I'd like to present this package to everyone in XDA.

    To do that, you must be familiar with how to roll back your phone to Windows Phone 8.1. Windows Device Recovery Tool is necessary.

    Instruction:
    1. Make backup for your phone, for example, copy data to your PC. And make sure the OS of your PC must be at least Windows 7 Service Pack 1. Windows 8/8.1/10 are also acceptable, but you must install every Visual C++ Redistributable Runtime and Windows Device Recovery Tool.
    2. Check your OS version in about phone. The OS version must be at least 8.10.14219.341 or newer. If the version is lower than required, please update it. You may want to use Windows Insider app from Windows Store. REMOVE YOUR PIN LOCK to prevent from some unknown issues after an upgrade.
    3. Download and open the package by 7-Zip. Choose your model and extract the exact folder from it. For example, Nokia Lumia 820 should extract 480x800 folder from 2nd Generation folder. DO NOT EXTRACT cabs in that folder.
    4. Press Win(Command)+R, in run command dialog, type "control printers" and run. Unplug your phone and remove your phone in Device and Printers window.
    5. Extract iutool package attached below, and open a command prompt window with Administrator privilege. Change working directory to iutool.exe's location.
    6. Plug your phone to your PC, then type this command:
    iutool -l
    7. If your phone is shown in command prompt window, then type this command:
    iutool -V -p D:\480x800
    (For example I have extracted this folder in Drive D)
    8. Wait for about 40 minutes, then your phone will be in Win10 Mobile 10586.107.
    9. Open Developer mode in "For Developers" option, then deploy tools that could modify phone's model to your phone.
    10. Use any method that you know to modify your model, for example, I modified model to Microsoft RM-1116 (Lumia 950 XL Dual SIM). If you are going to use VCreg or Interop Tools, you needn't to Restore NDTKSvc.


    11. Check update, and you will receive another update to Win10 Mobile 14393 or later stable builds. Update to this build will fix critical issues you met.
    12. After the update to another build, I recommended you to perform a hard reset to your phone. That would make the phone works at the best state.

    Known issues:
    - If the pre-installed default IME doesn't include English (United States), after an upgrade by this offline update package, pre-installed IME won't work. Please make sure your firmware's pre-installed IME included English (United States). However, if you modify your model by using Interop Tools by gus33000 then perform another update, IME issue will be fixed. Because this update package is made for Chinese users and China variant firmware at first, I couldn't take care of every variants. Sorry for that.
    - To HTC 8X/8XT users: I'm sorry for the promise I made, but the packages doesn't work on HTC 8X/8XT because the MainOS partition is too small to upgrade. That's HTC's mistake.
    - To Nokia Lumia 638 users: Please flash the latest China Variant Firmware (India Variant is not as stable as China Variant) to make sure the phone works at the best state, then download Upgrade Advisor from Windows Store to upgrade.
    - To Prototype model users especially the cancelled model: Please make a full backup of phone first by using WinHex or something else. If you didn't do that, unbrick the prototype model is almost impossible.
    - Because phones with 4GB ROM aren't capable for these package such as Nokia Lumia 530 and HTC 8S, this update package is not suitable for these models.
    - To Nokia Lumia 1020 users: Update to Windows 10 Mobile will reduce the performance of precious 41MP Camera. If your Nokia Lumia 1020 is used for photography, DO NOT UPGRADE.
    - Glance screen feature will be lost after another update to 14393 or later build, but it's possible to fix by using Interop Tools by gus33000.
    - To Samsung ATIV S (GT-I8750) and ATIV SE users: Offline Update Packages to WP8.1GDR1 or GDR2 is available now. Now you can update to WP8.1GDR1 or GDR2 without using SDK Deployment.
    - To Samsung ATIV S (GT-I8750) users: make sure you are using XXDOC2 firmware before update.

    If your phone's pre-installed keyboard is neither English (United States) nor Chinese (Simplified, PRC), you'll meet a problem that your default keyboard doesn't work. To fix it:
    1. Download the Internal IME Fix Package from the link below.
    2. Extract your keyboard layout with your language code, for example, if you are using English (United Kingdom), extract the cab with en-gb from that package to the root of drive D, and rename it to 123.cab.
    3. Open a command prompt window with administrator previlege, and change working directory to where iutool is, type this command:
    iutool -l
    4. Make sure your phone is listed in the output. Then type this command:
    iutool -V -p D:\123.cab
    5. You will encounter an error with code 8024a110, do not panic, the phone is still working with that package. The phone will reboot soon and perform another update to fix your keyboard.
    6. After the update, you're able to use your keyboard. Modify phone model with VCreg or Interop Tools, and search for another update, remaining keyboard layout and pre-installed speech package will be fixed along with that update.
    Here's some of the possible used language code in case you don't know how to choose:
    de-de: German
    en-au: English (Australia)
    en-ca: English (Canada)
    en-gb: English (United Kingdom)
    en-ie: English (Ireland)
    en-in: English (India)
    fr-ca: French (Canada)
    fr-fr: French (France)
    ja-jp: Japanese
    ko-kr: Korean
    zh-hk: Chinese (Traditional, Hong Kong)
    zh-tw: Chinese (Traditional, Taiwan)

    You can also enable Mobile Enterprise on your phone. Just extract MobileEnterprise.ppkg from Enterprise_Configuration_File_for_TH2_Builds folder, and copy it to your phone, then tap "Yes, add it" on your phone. Soon your phone will become into Windows 10 Mobile Enterprise. Reboot your phone, Settings - Phone Update, Advanced options, and there's a "Defer Upgrade" available, now check it, then search update. If you still can't get any update, please modify your model and search update again.
    Thanks for the collection here: http://forum.xda-developers.com/win...m-builds-update-links-collection-cab-t3234805 , and now it's possible to upgrade old models without Unlock Bootloader and Interop Unlock with SD card and WP8 SDK.
    P.S. Only V4 and V3 set available here. V1 and V2 are deprecated and archived in Chinese Community.

    Little hints:
    - If your Lumia 830's navigation keys aren't responsible, you can push packages for Lumia 73X or Lumia 640/XL.
    - If your Lumia 1520's navigation keys aren't responsible, you can push packages for McLaren.
    - The directory catagory is depended on resolution, SoC, Virtual Navigation Bar availability, stock language packages included in firmware, etc.
    - DO NOT USE Interop Tools provided in Windows Store.

    In case that I can't give you help in time, here's some troubleshooting info for you:
    IUTool Command Error Codes List: https://msdn.microsoft.com/en-us/library/windows/hardware/mt131833(v=vs.85).aspx
    Also, if you encounter a error, don't unplug your phone, type command "getdulogs -o 123.cab" and waiting for Device Update Logs output. Open the 123.cab and open ImgUpd.log to get some hints. If you are a developer, you should be sensitive to error code lines.
    Or, just attach the 123.cab to here.

    - Because phones with 4GB ROM aren't capable for these package such as Nokia Lumia 520/520T/521/530 and HTC 8S, this update package is not suitable for these models.

    520/520T/521 has 8gb ROM.

    If your phone's pre-installed keyboard is neither English (United States) nor Chinese (Simplified, PRC), you'll meet a problem that your default keyboard doesn't work. To fix it:
    1. Download the Internal IME Fix Package from the link below.
    2. Extract your keyboard layout with your language code, for example, if you are using English (United Kingdom), extract the cab with en-gb from that package to the root of drive D, and rename it to 123.cab.
    3. Open a command prompt window with administrator previlege, and change working directory to where iutool is, type this command:
    iutool -l
    4. Make sure your phone is listed in the output. Then type this command:
    iutool -V -p D:\123.cab
    5. You will encounter an error with code 8024a110, do not panic, the phone is still working with that package. The phone will reboot soon and perform another update to fix your keyboard.
    6. After the update, you're able to use your keyboard. Modify phone model with VCreg or Interop Tools, and search for another update, remaining keyboard layout and pre-installed speech package will be fixed along with that update.
    Here's some of the possible used language code in case you don't know how to choose:
    de-de: German
    en-au: English (Australia)
    en-ca: English (Canada)
    en-gb: English (United Kingdom)
    en-ie: English (Ireland)
    en-in: English (India)
    fr-ca: French (Canada)
    fr-fr: French (France)
    ja-jp: Japanese
    ko-kr: Korean
    zh-hk: Chinese (Traditional, Hong Kong)
    zh-tw: Chinese (Traditional, Taiwan)

    You can also enable Mobile Enterprise on your phone. Just extract MobileEnterprise.ppkg from Enterprise_Configuration_File_for_TH2_Builds folder, and copy it to your phone, then tap "Yes, add it" on your phone. Soon your phone will become into Windows 10 Mobile Enterprise. Reboot your phone, Settings - Phone Update, Advanced options, and there's a "Defer Upgrade" available, now check it, then search update. If you still can't get any update, please modify your model and search update again.
    Thanks for the collection here: http://forum.xda-developers.com/win...m-builds-update-links-collection-cab-t3234805 , and now it's possible to upgrade old models without Unlock Bootloader and Interop Unlock with SD card and WP8 SDK.
    P.S. Only V4 and V3 set available here. V1 and V2 are deprecated and archived in Chinese Community.

    Little hints:
    - If your Lumia 830's navigation keys aren't responsible, you can push packages for Lumia 73X or Lumia 640/XL.
    - If your Lumia 1520's navigation keys aren't responsible, you can push packages for McLaren.
    - The directory catagory is depended on resolution, SoC, Virtual Navigation Bar availability, stock language packages included in firmware, etc.
    - DO NOT USE Interop Tools provided in Windows Store.

    In case that I can't give you help in time, here's some troubleshooting info for you:
    IUTool Command Error Codes List: https://msdn.microsoft.com/en-us/library/windows/hardware/mt131833(v=vs.85).aspx
    Also, if you encounter a error, don't unplug your phone, type command "getdulogs -o 123.cab" and waiting for Device Update Logs output. Open the 123.cab and open ImgUpd.log to get some hints. If you are a developer, you should be sensitive to error code lines.
    Or, just attach the 123.cab to here.
