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.

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.
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:
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.

- 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:
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:
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)
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/wind...n-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.
- 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/lib...(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.
