Huawei P8 Lite ALE-L21 BalongC52B311 Solution and upgrade to marshmallow

as i am not huawei P8 user, but one my reader contacted me and told about balong bug which appeared in P8 lite, this bug makes your OS unstable and unrecognized by google & play store services. it doesn’t accept sim cards from all network operators and sometimes it crashes your themes, and several other issues reported.

usually it happens when a user try to flash wrong firmware or a firmware from another region, or try to convert it from single sim to dual sim or vice versa.

Solution (Applies to ALE-L21 & ALE-L02)

Before i continue with instruction you should take care of following things
  • Boot loader unlock code (How to get unlock code)
  • Take complete backup of your phone data
  • unroot it if you have rooted (in superSU there is full unroot option)
  • Stock Recovery( if you have installed twrp revert back to stock recovery)
  • Enable USB debugging

During this process we have to downgrade your phone back to lollipop, but that can not be done by simply flashing the old firmware, you have to flash each image file manually. once you are ready to proceed , follow this step by step guide.
  1. Dwonload Minimal ADB and Fastboot ,  after installation, launch it by double clicking “MAF32.exe” inside C:Program Files (x86)Minimal ADB and Fastboot.
  2. Connect your phone with PC & type “adb devices” your phone will ask for permission, check always allow from this pc & grant permission.
  3. Then type following command

adb reboot bootloader

Let the window install drivers, then type

fastboot oem unlock xxxxxxxxxxxxx

(xxxxxx is your unlock code) and your phone will be unlocked

1. Download ALE-L21C432B052 EUChannel Android 5.0 EMUI 3.1 Firmware, Extract “update.app” from the downloaded firmware file and open it with huawei update extractor, as shown in image below.

  42. Unknown says:

    Sir I take my hat off to you!! Thank you very much , I had this balong issue for months and now tha phone is fully operational again thanks to you!! Greetings from Greece.

  43. but I have a little problem, the phone doesn't receive OTA updates, it still has B170

  44. This comment has been removed by the author.

  45. Don't wait for ota, download marshmallow by yourself & install it over B170, just read my post, last paragraph, its about marshmallow update

  46. Thank you , I'll try that

  47. Worked and also an update showed, now I have B574 android 6.0 with no balong anymore, by the way I accidentally unlocked the dual SIM feature so double win

  48. Lolz its not an accident, but the firmware you used in 1st step actually converts phone to dual mode.

  49. Cool.One last thing ,when I was at android 6.0 with balong the phone didn't load some of my photos on gallery or any video with the system app and usually both apps crashed,now again in 6.0 without balong I notice the same thing, do you have any idea what might be? (In 5.0 I had no problems)

  50. To me looks like corrupted files in storage, take new photos & videos then try to open them, if app doesn't crash with new photos /video ,
    then follow this step. Backup your data using Hisuite software.
    Then format internal storage,
    Restore data.
    Hopefully it will resolve your issue.
