Downgrade from MM to LP - P8lite Q&A, Help & Troubleshooting

I have ALE-L02 with C636B530 I would like to down grade to C636B150
I have seen procedure for ALE-L21 will this be similar ?
Or can I just do the EMUI method but with the old UPDATE.APP ?
or will this lose my IMEI ?
Anyone with any clues ?
Thanks

I am on ALE-L21 but fo sure the procedure is like the that
with UPDATE.APP does not work and remember that EMUI 3 have a different modem so the only way it's the method with FLASHALL.bat

They have rollback version. This is srilanka rollback version. I think you can try with this.

anything that works on the l31, c432 means it's the european variant
So all L31 variants work? Or is there differences in lte bands lets say like 432 and 185 variants ?
You can flash whatever rom version you want.
As most of us, we've installed vns-l31c185/c636b360(latest version of Nougat) and we don't have bugs or problems.
No matter what oem info it has (oem info is the Variant/region of the phone, like c432 is for Europe, c185 is for mena , c636 asia i guess, correct me if I'm wrong) The version will be compatible with your phone.
I don't know if there is differences between oem info of each region , personally i installed c185b360+ the additional package of c432b328 over c432b161,( i was in mm and went to nougat) and i dont have problems with mobile data.
@simo255
Thanks for the answers. Like i said i currently have rooted L31c432b336 and revolution recovery.
If i want to update b360 should upgrade through dload method or twrp?

Via twrp you can flash nougat without changing oem info. If you want to update via dload you must have the oeminfo of the rom you want to install.( So if you are on C432 you can t flash C185 Ffirmware via dload because you havr c432 oeminfo) but be carefull..there arr lots of bricked devicea.

Sorry to rub it, but I want to be sure because I already had troubles when upgrading to nougat.
But....so in twrp I can just flash the bigger (abt 1.2gb) file and its should work? No need to flash second smaller zip?
I have had Sony devices past 3 year and I have used to flash those

Ive ashed the second file and it gaves me errors
Like i did , flash the bigger size and the additional package, take a look at my thread : https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932
I will follow simo225's instructions.
Now I'm beginning to wonder what is the differences between smaller zip and additional zip, because I thought they were the same :laugh:

The C900 version

Hi, recently I tried to upgrade my P9 lite to Nougat using Firmware Finder app. I downloaded and installed the B361 version but it was all buggy so I decided to do a rollback to MM. After doing the rollback I got a C900B160 version.
Is this C900 version a problem? Should I change it to C423?
Also, why was the B361 Nougat so buggy? Did I do something wrong?

if you flashed rollback package its ok to get that. just put marshmallow CxxxB161 ( Cxxx- means your number C432 C02 etc.. ) then with 3 buttons method flash marshmallow and you are good to go.

I already flashed the MM and it is still a C900 version, I downloaded it from official emui website as I remember.

You need to flash oeminfo and custom.bin from fastboot .( Your bootloade needs to be unlocked. ) You can check huawei tool thread . There you will find what you need)

Proxy method?
Better let someone else handle the updating, seeing as you're don't like reading too much.
Dude, don't be salty because getdroidtips isn't clear.
I managed to update btw, close this topic

Dude use Firmware Finder app and dns/vpn method
to try to force the upgrade ( try to use B361 FULL OTA-MF PV first ).
If all will take right direction, then use same method to update to
B502 (dual sim) or B503 (single sim) FULL OTA-MF version.
See the attachtments and good luck.
Cheers

Dear,
huawei never planned to forward oreo official upgrade to p9 lite ( 2016 aka venus model ) users,
so do not waste your time looking for this, it simply doesn't exists...
B502 ( dual sim ) / B503 ( single sim ) are latest Nougat firmware.
Cheers

Firmware Finder is down bro, definitively. You can try to upgrade using dload method. Download Service ROM for dual SIM
and flash it, instructions can be found in ReleaseDoc folder. This process will erase all your data (and lock the bootloader again) !
I hope you have Dual SIM variant. If not, let me know.
