Huawei P8 Lite ALE-L21 BalongC52B311 Solution and upgrade to marshmallow(Convert to Dual Sim)
I am not a Huawei P8 Lite user, but one of my readers contacted me and told me about balong bug which appeared in P8 Lite, this bug makes your OS unstable and unrecognized by Google and Play store services. it doesn’t accept sim cards from all network operators and sometimes it crashes your themes, and several other issues are reported.
Usually, it happens when a user tries to flash the wrong firmware or firmware from another region or tries to convert it from a single sim to a dual sim or vice versa.
Solution (Applies to ALE-L21 & ALE-L02)
Before I continue with the instruction you should take care of the following things
- Boot loader unlock code (How to get unlock code)
- Take a complete backup of your phone data
- Unroot it if you have rooted (in superSU there is a full unroot option)
- Stock Recovery(If you have installed TWRP revert back to stock recovery)
- Enable USB debugging
- Battery charged 100%

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.
- Download Minimal ADB and Fastboot , after installation, launch it by double-clicking “MAF32.exe” inside C: Program Files (x86)Minimal ADB and Fastboot.
- Connect your phone with a PC & type “adb devices” Your phone will ask for permission, check always allow from this PC & grant permission.
- Then type the 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 the Huawei update extractor, as shown in the image below.
2. Download Huawei update extractor, install & open it then browse for “update.app” in it as shown in the image below.
3. Once it opens you will see a list of files, you have to select only 4 files from it,
- Boot
- Cust
- Recovery
- System
To select multiple files hold the CRTL button on the keyboard. once you selected these files right-click on any selected file and click “extract selected” as shown in the image below.
4. Make a new folder on the desktop with any name, and extract these 4 files in that folder.
***Very Important Step***
5. Now Download ADB Installer for P8 Lite. and extract all files in the same folder where you saved those 4 files. as shown in the image below
6. Switch off your phone, hold the volume down button & connect it to your PC, You will see a white screen saying Phone unlocked, as shown in the image below
7. Now Double click on “install.bat” file and installation should start, you have to wait a little bit longer, as this process may take 45 to 60 minutes.
8. Once you finished installation, you should reboot your phone, your phone may take some time to boot up,
9. Now download this Vendor Information File, extract it, and copy the “dload” folder in sd card/internal memory of your phone.
10. Go in settings>updater 7 select”update.app” and start updating, Your phone will Factory Reset and you will see the balong bug has been fixed.
11. Now we will start the Marshmallow Upgrade process,
12. Download this firmware: ALE-L21C432B170 EUChannel Android 5.0 EMUI 3.1 DUAL SIM, extract “update.app” copy inside the dload folder, and start the update, after the successful update, you will be on lollipop 5.0 without Balong bug,
13. Now OTA updates will start to appear on your phone, You should install all of them, and the sequence will be like, B188, then B194, etc.
14. once you stop getting updates download this marshmallow firmware: Huawei P8 Lite Firmware (ALE-L21, Andriod 6.0, EMUI 4.0, C432B564, CEE&Nordic European, Channel-Others, Dual)
repeat the same process extract “update.app” and copy to the dload folder, and update. On the successful update, you will see your phone has Marshmallow B64 installed without the Balong bug

Is it bad if my phone doesn't find any updates after the b170 software update?

Hi Do you know if it is possible to make the Huawei P8 GRA-L09 read dual sim.
I think no, the sd card tray in this phone isn't designed for sim card
Ohh I cant unlock phone cuz in cmd it says when I typed my code. any suggestions ? Thanks
Edit : it says " waiting for any device "
Make sure usb debugging enabled
I found the problem. My pc wont install fastboot drivers , so maybe you have a link to download them manually ?
Will try this out, but can i use b574 instead 564 ?
Yes if you have B574 full firmware,
Then you can use,
Otherwise you will get update notification right after installation
There is nothing like fastboot drivers.
R u able to connect device in normal mode?

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.
but I have a little problem, the phone doesn't receive OTA updates, it still has B170
This comment has been removed by the author.
Don't wait for ota, download marshmallow by yourself & install it over B170, just read my post, last paragraph, its about marshmallow update
Thank you , I'll try that
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
Lolz its not an accident, but the firmware you used in 1st step actually converts phone to dual mode.
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)
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.
vendor file update failed for me im tired bulshit balong please help me
Don't worry, where you from?

Yes, its clearly written balong solution
SIR I HAVE DONE PROCESS
NOW HOW TO WRITE VONDER INFO IN SETTING . UPDATER WHERE IS OPTION TO CLICK ON UPDATE.APP I CANT FIND PLZ GUIDE ME
Can i do the last step with the B588 firmware too?
Try at your own risk
Worked like a charm!
Just a few notes:
– after installing ALE-L21C432B052 EUChannel the system rebooted a lot, I couldn’t do anything, but after 12 or so reboots, it worked!;
– I didn’t have to install ALE-L21C432B170 EUChannel, the OTA update took care of that;
– after OTA update to ALE-L21C432B170 EUChannel, I received also OTA update ALE-L21C432B574-NEW EUChannel, which I currently use;
– bottom line: thank you so much for helping me with this tutorial for removing the Balong “bug”!
Much appreciated!
Oh, and for some reason the Vendor file it was not needed (it didn’t work for me).
After installing ALE-L21C432B052 EUChannel I lost my imei, but I got it back with ALE-L21C432B170 EUChannel.
Thanks again!
Because your phone was already European, and you are in European region, that’s why updates came in correct fashion,
Thanks for feedback.
Update: received OTA ALE-L21C432B584.
what should i do if this occurs? it keeps rebooting,
I was literally thinking about buying a new device. You saved my life <3
Thanks very for this tutorial, problem solved after few attempts. Balong bug, gone. I got one update after that ALE-L21C432B170. then I just installed ALE-L21, Andriod 6.0, EMUI 4.0, C432B564, manually. all looking good now. thanks again.
Thanks you, no more balong and dual sim activated! (Before I was on SFR FR Single SIM)
thank you sir it’s helpfull
Hello sir! I have Balong, but with Android 5, will this still work for me?
100%
Thank you! But if it will somehow fail, it will not brick my phone, right? I tried to root my phone and bricked my phone and now I am kinda scared 😀
One more thing o offer remote service, if you are afraid, then i can do it through TeamViewer. But it’s not free 🙂
This method is tested and working for everyone, but i don’t take responsibility if you make any mistake
Thanks for your guide. After trying different methods of upgrading from Europe Single SIM (operator Orange Romania – when I bought they said is dual sim 🙁 ) to Dual SIM, it worked with your method … till step 8.
After update, step 7, the phone kept rebooting. After o few reboots displayed a page saying user data corupted with some options, reboot, factory reset … I choosed factory reset … after the fw was still Balong … then executed step 9 and used Volum Up and Volum Down and Power button press to start update from SDCard. Phone reseted to factory default – EMUI 3.1. After setting and reseting the phone got dual sim active, but not for my operator – SIM Rejected.
Then got to step 12 and used the firmware from Huawei site version B584 (previous version – now is 594 – Dual SIM and 595 Single SIM) copied to SDCard and started the update procedure … wait again some time … After that the phone worked ok – dual sim options active – inserted two sim from different operators and work fine.
After setting wireless connection the update informed for a new version available and done OTA full update to ALE-L21C432B594 : 1.56GB.
The phone is working fine.
Thanks again for the good job !
