Help!! ¿How to downgrade C185 p8 lite from B160 to B120? - P8lite Q&A, Help & Troubleshooting

I tried the usual flashing method but it failed. I think it needs flashing intermediate package between b120 and p160. I am not familiar with huawei firmware flashing rules, so please help me.
If more info is to help you help me, I tell you what happened :
#I bought my p8lite ALE-L21 from Egypt once switched on it received TWO consecutive updates. Unfortunately I don't remember the original build, but now it's on C185B160.
# I then unlocked bootloader, rooted it with kingroot, flashed twrp then removed some bloat ware. Unfortunately I removed some good features by mistake.
#I thought reflashing the b160 build would bring back stock, but I never found such B160. # Someone advised me to flash B120, I downloaded The B120 designed for p8 lite C185 but failed to flash again.
WHAT SHOULD I DO NOW. ANY HELP WILL BE APPRECIATED.

Any Help please????

please somebody help us

p9 lite bricked, i need the b125 full!

I have installed the b161 update nobrand on my vodafone p9 lite, now i can't complete the initial setup, i searched for the vns-l31c02b125 full update, but i found only the ota, someone can help me?
I had the same problem last weekend,
Just install the L31C02B123 and the update to the B125 via OTA.
Downside is that you'll loss root and all. I hope you have a backup.

[Firmware] Which firmware should i use to update to emui 5.xx with VNS-L31 C432 B226?

My phone had to be repaired last week, and the Huawei repair service changed everything in the phone except for the backplate.
However, I am now stuck with emui 4.1.2 in firmware VNS-L31 C432 B226, and i can't find a replacement firmware for the system.
The phone shows no update available in stock.
I have TWRP and magisk installed atm, just so i could try and get a different firmware with emui 5.1 or 5.0 at least, which I did to no avail.
Is there any way to find the correct firmware compatible with this phone?
Googling this firmware gives me no clues as to the correct path to updating this phone.
Should i use an adb/fastboot command prompt to update it, or use the dload method, or even the extract the SYSTEM.img from UPDATE.app method?
I just don't want to revert to an "earlier" version of the firmware with the dload method just to have my phone bricked.
These are the firmware i tried already:
[TO BE UPDATED]
TL/DR:
I have a Huawei P9 Lite repaired to a stock:
Firmware: VNS-L31 C432 B226
EMUI: 4.1.2
in Portugal.
I want to know a compatible firmware or series of firmware patches so i can get
Firmware: VNS-L31 C432 Bxxx
EMUI: 5.xx
Thank you for your time.
Hello,
it's strange that with an unbranded european firmware your phone didn't upgraded to android 7....
Anyhow i never done a forced upgrade but if i were you i wil try with HWOTA update, like explained in this thread.
So first make all your necessary backups, then unroot and finally follow the guide to upgrade.
P.S.: If your phone is dual sim try install B370, if single sim try with B371.
All the best

I tried a bunch of firmwares for emui 5.1 that didn't work, or which had NFC and bluetooth not working. I ended up downgrading to B160, and am now reupgrading to B370 after checking that both of the previously mentioned are working properly. I will update on this issue asap.
Also, it seems like the firmware I originally had was updated in march 2018, so it was really an updated official firmware with emui 4.1. What a weird setup. Could it be to make sure the NFC and bluetooth would be working? I just don't know...

Yeah, downgrading to B160 should be a good choise..
Use then stock updater to look forward

I did it and it worked, however i flashed the recovery partition of version VNS-L31C432B380 with TWRP and now can't do a OTA update to B388.
Should I extract the recovery img from a b380 FULLOTA update and flash it to my recovery partition with fastboot?

Hey,
surely without stock recovery OTA updates won't work,
so yes try flash it with fastboot, then update to the latest/wanted firmware and finally unlock bootloader,
flash custom recovery and root (even if wanted).
Best regards
