P9 lite rollback problem - Huawei P9 Lite Questions & Answers

Hello Everyone
I lost my Bluetooth and many apps in p9 lite after rollback by a firmware whose (size is 75mb olny) now my built number is l21 NRD90M test keys
Plz help me how i solve it how i use Android 6 or 7

Hi , first you should install the rollback file , then should install the Android 6 rom . I did it many times and it worked . I suggest you to install them by buttons , I guess it was POWER + VOLUME DOWN + VOLUME UP

Light Painting Camera on p8 lite

Hello guys
I've installed Chinese Marshmallow update on my p8 lite ale_l21
the stock camera includes Light painting mode ( it was awesome ),
but i couldn't continue with that
firmware because it 70% based on Chinese language , also it does not support google play services ..
So i flashed my p8 lie and upgraded to euro marshmallow , i found this update not includes light painting camera or drive mode ( which has been included in Chinese marshmallow) ,,
I think if we could port (camera app) from the Chinese marshmallow for p8 lite we can flash it to p8 lite runs euro marshmallow via adb or root
Any developer can port it for us ?
Im just waiting
Thank you guys
Hey guys , any help?
You actually replied to your own post after 12 minutes because no one else replied? lol
You better have some more patience. I'm using the Chinese Firmware as well and I removed all the unavailable Huawei Stuff and also removed the Huawei start and exchanged it with nova launcher prime. Also, I flashed the Gapps so Play Store is actually working. There's no more chinese stuff that shows up, that's why you don't have to wait for a port and if you insist on the port, except for begging for it you could just do it yourself.

Install EMUI from Different devices between 4X(620)/4C/G PLAY/G PLAY MINI/P8 Lite

Hi there, i was asked to do this post, with tutorials of htcmania and 4PDA, i say now, if some user of 4PDA is reading this and you dont want to post your information, pm me and i will delete it
Install EMUI 4.1.1/4.1 on 4X/4C/G PLAY/G PLAY MINI/P8 Lite (ONLY ADVANCED USERS)
Hi, searching things on 4PDA , EMUI 4.1+ Can be installed on these phones without problems, simulating being other phone (in this case P8 lite or Y6II)
Before anything, you need to be on LP/MM, on KK IT CANT BE USED
ONLY ADVANCED USERS, DO IT AT YOUR OWN RISK
ON Y6II MOVE APP 2 SD USING STOCK METHOD IS DISABLED
IM NOT RESPONSIBLE OF DAMAGED PHONES, ETC, FOLLOW THE INSTRUCTIONS REALLY CAREFULLY
You need Unlocked Bootloader, TWRP (from 4X/4C or P8 lite, depends) then you go here
http://hwmt.ru/oth/HWFF/info/view.php?find_model=
AND YOU ONLY SEARCH FOR ROMS OF CHE2-XX, CHM-XX, ALE-XX, CAM-XX AND FULL (IT CANT BE OTA, I REPEAT, CANT BE OTA), AND DONT INSTALL 28/11/2016 B893 OF P8 LITE
Don't install roms from ALE-04, CAM-L32, CAM-AL00 and CHE1-XXX, they are snapdragon
Then you download this updateflasher.zip http://www.mediafire.com/file/w9ms2fh8fr0atxi/updateappflasher.zip
When you have both downloaded, you need to move the UPDATE.APP from the zip rom that you got, and move into the appflasher, it should look like this
http://imgur.com/a/2hElq
Now you move the zip to your phone, mount all partitions and install normally, it will give some errors but dont pay attention, it is normal
before first boot, wipe with the default recovery data and cache
Then, on 4.1+ the internal mem is encrypted by default, if you dont want this, install twrp, go to alongside advanced wipe, you press format data, write "yes" and then data is ok to go
Some Pictures
CAM-L21 http://imgur.com/a/Vaen7 (EMUI 4.1.X)
P8 Lite ALE-21 http://imgur.com/a/t1sZm (EMUI 4.1)
The main differences is these roms are optimized, a lot, really, they are really fast, and you get 3.3gb internal instead of 3.6
IF YOU WANT TO RETURN TO 4X/4C/ETC
Simply do the same process as you did with with the CAM-P8 lite rom, but with any rom of your real phone
i mean, for example if you have a g play and you want to return to it, just put any rom that is LP+ on appflasher and continue normally
If you want to disable navbar, change qemu.hw.mainkeys=0 to qemu.hw.mainkeys=1 (if it isnt on the prop, add it manually)

This is very informative. :good:
Did you tried flashing using adb?
---------- Post added at 12:30 PM ---------- Previous post was at 12:29 PM ----------
Anyone tried flashing using adb?
@trulalueclav some people tried on htcmania, but on p8 lite and it worked for them, 4x or 4c didnt tested via adb
thanks for the guide

why do you want a flashable zip?? go on and flash firmware..
No issues with different netcards? I see in P8lite thread about LineageOS ROM that this ROM can't work on Che2-L11 because of the different netcards. But is tested Y6ll ROM on my Che2, and is runs fine, like on P8lite. Confusing....
@Iceman66 that only applies to custom roms, not for emui roms (i'm using a p8 lite rom atm)
for custom roms, they are incompatible (except if someone ports in, but on 4X sub forum nobody cares for the che2 version, only for the che1 version, so we have no devs)
Thanks, maybe there are no devs with a Che2 device ...... Haky had a honor 4c.

Hello,
I installed CAM-L21 B141 today... I have few questions...
1. how to move apps to sd card?
2. how to enable otg?
3. double tap to wake feature.
4. how to remove 4G option from network settings and from navigation bar and from preferred network type?
To be honest I have to say This is one of the great work ever done for this device! +1 ?
Thanks in advance.
