More information about this device:


DIFFERENT VARIANTS AND VERSIONS OF Honor 3C
There are now five main versions of Honor 3C that i am aware of:
H30-U10 (联通2G), H30-T00 (移动1G), H30-T10 (移动2G), H30-L01 (移动4G) and H30-L02 (联通4G).

Most guides and resources provided on this thread are dedicated to Honor 3C 2G H30-U10 with MT6582 chip.
But guides like SD Upgrade and ROM flashing using SPFT might also applicable to other variants with MT6582.
Just make sure you don't mess up and use only files dedicated to your device, please check, and double check.


Since we will be working with Honor 3C H30-U10, let's discuss some known variants of this version.
  • International set: Comes with LOCKED bootloader. (Ref. Build number: H30-U10 V100R001C900B1XX)
  • China set: Comes with UNLOCKED bootloader. (Ref. Build number: H30-U10 V100R001CHNC00B1XX)
  • Europe set: Comes with LOCKED bootloader. (Ref. Build number: H30-U10 V100R001C432B1XX)
Note: International set sometimes referred to as global, MY (Malaysia) or TW (Taiwan) set.

Restoring Single Partition using SPFT (NVRAM, PRO_INFO, ETC) (Restore IMEIs)

Quote:

What's this all about?
* You can follow this guide to restore individual/single partition which cannot be restored using standard 'Download' method.

Warning:
* Usually you DO NOT need to use this function, except when you accidently wrote to wrong partition, or ran a Full Format through SPFP.

Tips:
* You will need backup file created by SPFT's Read back function, and processed by dumpSplitter. (You can also use files from MtkDroidTool)
* These special partitions backup files can be found under 'ROM_READ\OUTPUT\NoDL\' folder and start with 'nodl_' prefix.
* For this guide, i will be using NVRAM that stores calibration data, device IMEIs, etc as an example.
* You can also use the same method to restore almost all partition, provided that you know the start address of the target partition.


1) Open SP FlashTool, enable 'Write Memory' under [Window] drop down menu.



2) Switch to 'Write Memory' tab and click [Open raw data] button.



3) Browse to 'Honor3C' project dir and select folder 'ROM_READ' and click 'Open'.



4) Select folder 'OUTPUT' and click 'Open'.



5) Select folder 'NoDL' and click 'Open'.



6) Select the file 'nodl_NVRAM' and click 'Open'.



7) Change Memory Setting to 'EMMC', Begin Address to '0x1800000' and use File Size value as Container Length.
8) Double check everything is entered/selected correctly, then press 'Write Memory'.



9) SP FlashTool is waiting for connection, now connect your phone to computer using USB cable, WITHOUT the battery inserted.



10) SPFT has successfully established a connection with the phone, the writing process will begin.



11) The following GREEN circle will be displayed if the download succeeded.



12) Now DISCONNECT the USB cable from your phone.

Force Upgrade / Installing ROM using UPDATE.APP (Method #1)
Quote:

What's this all about?
* Incase you haven't heard about 'UPDATE.APP', it's one of the format used by Huawei/OEM to pack ROMs & provide updates.
* This method requires a MicroSD with minimum size of 2 GB as the ROM itself could cost 1.2 GB for newer version of android, eg: KitKat.
* Under normal 'Local Upgrade' mode, you are ONLY allowed to upgrade if your current version is listed under the ROM's supported version.
* But with 'Force Upgrade', we can bypass version check and upgrade/downgrade to any supported ROM, as long as it's made for the device.

Warning
* You must be running stock recovery in order for this to work, otherwise use method #2 below to call this function.
* Although it's called 'upgrade', it's not actually an upgrade, it's more like a Full Reset as data partitions will be cleared.
* Make sure the phone is fully charged as the upgrade process is power-intensive and will drain your battery quickly.


1) Download the target ROM file, extract the zip, copy extracted 'dload' folder to SDCard as '/sdcard/dload/UPDATE.APP'.



2) Power off the phone, restart the phone by holding [Volume Up/+] & [Volume Down/-], then press & hold [Power] button.
3) The phone will be booted into recovery and the upgrade process will begin automatically.

* The upgrade process takes around 3-10 minutes depending on your memory card speed.



4) Once the upgrade process completed, a large 'OK' text similar to below will be shown and the phone will reboot by itself.



NOTE: If you are having International (aka MY/TW) set and upgrading to non-official ROM, you might also get the following error.



* The error was caused by missing preset in /cust partition specific for your country/region in non-official ROM, eg: ROMs from emui.com.
* Don't worry as it won't affect the phone basic functionality, just restart the phone manually if you get the error message.

Force Upgrade / Installing ROM using UPDATE.APP (Method #2)
Quote:

What's this all about?
* Similar to method #1 above, this method can also be used to bypass version check when flashing 'UPDATE.APP'.
* Unlike method #1 above, this method calls the target ROM's recovery and enter SD Upgrade with the help of 'au_temp.cfg'.
* This method can be used even you are not using stock recovery, eg: installed a custom recovery.
* However, NOT all target ROM support calling upgrade using this method, if that is the case use method #1 above.


1) Download the target ROM file, extract the zip, copy extracted 'dload' folder to SDCard as '/sdcard/dload/UPDATE.APP'.

2) Create an empty file 'au_temp.cfg' and copy it to '/sdcard/dload/au_temp.cfg' alongside 'UPDATE.APP'.




3) Power off the phone, then start the phone normally by pressing [Power] button only.

4) The phone will be booted into recovery and the upgrade process will begin automatically.


* All remaining steps are similar to method #1 above. (Step 3 onwards)

Reverting to / Restoring Stock Recovery (New!)
Quote:

What's this all about?
* Some people prefer custom recovery (eg: TWRP, CWM) over stock recovery because the earlier provides more functionality.
* However, custom recovery does not work well with Huawei specific update files, for eg: EMUI OTA zip and UPDATE.APP.
* Because of this you will need to restore the stock recovery before you perform any EMUI related update.
* Please note that the 'stock recovery' we are talking about is the 'Android system recovery <3e>'.


1) Download recovery flashable stock recovery 'UPDATE-RestoreStockRecovery_*.zip' from HERE.

2) Copy above .zip file to your external sdcard.

3) Boot into your custom recovery, eg: TWRP and flash (Install) the updater zip that you just copied.

4) If the flashing process completed successfuly, you should have the stock recovery restored to phone memory.

5) To confirm, back to [Home], enter '[Reboot/Power]' menu and choose 'Reboot into Recovery'.

Everytime you exit from stock recovery, /data/cust will be updated, this could be useful if you have upgraded /cust manually.


1) Power off your phone, boot into recovery using key combinations of [Volume Up] + [Power]

If you are running 4.2.2 JellyBean Stock Recovery (B11X)


2) Use Volume +/- keys to move highlight to 'wipe data/factory reset', then press [Power] button to select.

5) Select 'reboot system now' and press [Power] button to restart the phone.



6) If you receive the following error message, just repeat step #5 above.



* The above error was due to missing localization data in /cust partition, likely true if using non-official ROM on global set.

2014/11/19 - TWRP updated to 2.8.1.0, FullRootHelperV2 released, minor bug fix.


IMPORTANT NOTE
- ModemFix has been tested on unofficial EMUI 2.3 only, DO NOT flash it for more than 1 time.
- Please remember to switch your 'Storage:' in TWRP to external memory (MicroSD) before making backup.
- As of TWRP 2.8, external storage (MicroSD) will be mounted at /external_sd in recovery. (was on /sdcard)

EXTRA: Working With UPDATE.APP - Making it flashable for SP Flash Tool
Part #1 - Converting Huawei UPDATE.APP to SP FlashTool Flashable Files
Quote:

What's this all about?
* OK, now you know you can apply update using 'UPDATE.APP' by placing it in /sdcard/dload/ folder.
* But do you know there is another way to flash the images directly with computer? Yes there is, by using SP FlashTool.
* This can be quite useful (and dangerous too) as you can skip/bypass the version check enforced by Huawei/OEM.
* Other than that, this method can also be used to install non-official ROM, provided that the ROM is compatible with the device.

Warning:
* Make sure you use UPDATE.APP that was built for your device, in this case, Honor 3C (H30-U10)


For this guide, i will be using update package H30-U10_EMUI_2.3_4.7.16.zip Dev KitKat build (860 MB+) as an example.




1) Download 'Huawei Update Extractor' by @worstenbrood HERE, get the non-setup version. (Don't forget to thank him!)

2) Extract the program files to a new folder named 'HuaweiUpdateExtractor' under 'Honor3C' project dir as shown below.



3) Extract the downloaded update package 'H30-U10_EMUI_*.zip', locate the extracted folder 'dload' and open the folder.

4) Inside 'dload' folder you have 'UPDATE.APP', move the file into 'ROM_UPDATE' folder under 'Honor3C' project dir.



5) Now back to 'HuaweiUpdateExtractor' program folder and launch the program.



6) Set Profile to Unknown, click the browse icon, browse to 'ROM_UPDATE' folder, select 'UPDATE.APP' and click 'Open'.



7) The images list should be loaded as shown below.



8) Right click on any item to bring up the action menu, select 'Extract All' and click on it.



9) Browse to 'Honor3C' project folder, select 'ROM_UPDATE' and press 'OK' button.



10) Wait until the extraction complete, this may take a few minutes...



11) Extraction completed, close the extraction dialog and the main program.



12) Open 'ROM_UPDATE' folder and verify that all images were extracted. (Folder size should be doubled now)



13) Click on '_PrepareFiles.exe' provided in the folder. (Required .NET 2.0+)



14) Now the ROM files are ready to be loaded from SP FlashTool.

Part #2 - Flashing ROM using Files Exported From UPDATE.APP
Quote:

Warning:
* Your device MUST be UNLOCKED in order to be able to flash using this unsigned ROM.
* Please note that ALL existing user data on the device will be removed as the partitions get formatted.

Tips:
* Although it's not compulsory but i recommend you to do a factory/data reset through recovery before booting the new rom for the first time.
* For international set users: If you are not flashing official ROM from Huawei, you will need to apply modem fix to regain call functionality.


Once you have prepared all the needed files from previous step, you can flash the ROM back to device.

1) Open SP FlashTool, click on [Scatter-loading] and browse to 'Honor3C' project dir, select 'ROM_UPDATE' folder and click 'Open'.



2) Select 'MT6582_Android_scatter.txt' found in the folder and click 'Open'.



3) The partitions info should be loaded as shown below, ALL items MUST be defined and checked.



4) Now press [Firmware Upgrade] button or 'F8' on keyboard.



5) SP FlashTool is waiting for connection, now connect your phone to computer using USB cable, WITHOUT the battery inserted.



6) SPFT has successfully established a connection with the phone, the upgrade process will begin.



7) SP FlashTool will format the target partitions first before writing to it.



8) Upgrade in progress, this may take a few minutes...



9) The following GREEN circle will be displayed if the upgrade succeeded.



10) Now DISCONNECT the USB cable from your phone.

Recommended extra steps

1) Re-insert battery to your phone, press [Volume Up] + [Power] button to enter recovery.

2) Perform a 'Factory Reset/Wipe data' before booting from the new rom for the first time.

How to upgrade to unofficial KitKat for International set users + Custom ROM preview
Honor 3C H30-U10 International set users,

Want to try out the unofficial KitKat EMUI 2.3 or latest 3.0 but think above guides are too complicated?
No problem! Let me summarize the upgrade process a little bit.



Prerequisites:
* Charge your phone, make some backups, sync your data, prepare a minimum 2 GB memory card.
* Download latest unofficial KitKat ROM in UPDATE.APP format from this page. (Press 'ROM包下载' under '开发版')
* Download TWRP Live Recovery, gapps-kk-*-signed.zip, UPDATE-SuperSU*.zip & optional UPDATE-*Fix*.zip.
* Extract the downloaded KitKat ROM zip & copy 'dload' folder to memory card as /sdcard/dload/.
* Also copy all others UPDATE*.zip to root dir of memory card, eg: UPDATE*.zip, gapps*.zip


Step by Step:
1) Power off the phone, enter SD Upgrade mode by pressing & holding both Volume+/- & Power keys.
2) Wait until the upgrade process complete and choose 'reboot system now', then proceed to the EMUI setup.
3) Check if your IMEI is available, if IMEI is missing remember to flash 'UPDATE-ModemFix*' later.
4) Connect the phone with USB to PC & replace /sdcard/dload/ folder with the one from Live Recovery.
5) Now reboot the phone normally and you will be booted into Live Recovery automatically.
6) In TWRP, touch [Install] & apply all the UPDATE*.zip. (SuperSU -> Gapps -> PermissionFix -> * ModemFix)
7) When done, return to home and touch [Advanced] -> [File Manager] and delete '/sdcard/au_temp' manually.
8) Reboot the device normally, done.

* Optional: ModemFix is ONLY applicable to International set users, only apply the fix if your IMEI is missing.

Warning:
Above steps can be done WITHOUT unlocking bootloader, HOWEVER, there are some limitations:
* You MUST NOT use 'Local Upgrade' or 'OTA' to perform update afterwards, otherwise a soft-brick *might* occurs.
* In order to be able to update through OTA, you MUST unlock the bootloader, then ALL update method can be used.
* To avoid such problem, it's recommended that you unlock the bootloader first before performing any upgrade.
* However, if you choose to unlock the bootloader, you may void the warranty of your phone, please decide wisely.
* Although reverting to factory ROM is possible, getting IMEIs back working in factory ROM is extremely tricky.
* DO NOT attempt to update to any unofficial ROM (including this one) if warranty is part of your concern.


Side Note:
* At the moment the KitKat ROM is still a developer build and might contain some bugs.
* It's recommended that you to revert back to official KitKat once it's available. (Check at huaweidevice.com.tw)


P/S: I strongly recommend you to create a Full ROM dump before you start flashing to device.
Beside SPFT Readback, you can also use MTK Droid Root & Tools by rua to dump your current ROM.
