GUIDE: How to upgrade to unofficial KitKat for International set users + Custom ROM preview

Want to try out the latest unofficial EMUI 3.0 KitKat but the above guides are too complicated for you?

No problem! Let me summarize the upgrade process a little bit.

UPDATE: This guide is NOT suitable for devices that come with build number: B127/B129/B111. (Touch issue)

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 '稳定版')

* 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 -> FullRootHelper -> * ModemFix)

7) Reboot the device normally, done.

* Optional: ModemFix is

ONLY

applicable to International/Europe 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

:

* It's recommended that you to revert back to official KitKat once it's available. (Check your local huawei site)

P/S: I strongly recommend you to create a Full ROM dump using 'SPFT Readback' before you start flashing to device.

You can also use MTK Droid Root & Tools by rua to dump your current ROM.
