Hello. I have bricked my p9 lite l21 recently and managed to make it work again hovewer now I have c432b161 firmware and cannot upgrade it further. Huawei ota does not find any updates, i have tried through the firmware finder app but even when the app shows its compatible, it still wont update (vol - + power updater shows information about it not being compatible). I have also tried installing it manually by twrp but the error 7 shows up. I think i have already tried b370, b371 and some others. What firmware should I install now to be able to update it to emui 5?

Recently picked up a P8 from someone who had one lying around.
I'm trying to root it but after installing TWRP i keep entering a bootloop which apparentely is counteracted by holding some combination of buttons.
currently im on B222 and i also tried installing marshmallow (stock) from SD which also makes me enter a bootloop and when my phone finally turns on its like it forgot it had a command to update.....
I'm a little lost on what to do now, i tried googling and all that but i cant find similar issues.
You cannot install Marshmallow with a B222 build, so you'll first need to downgrade to a B200 build.
If you are on a C432 (European) build, you can download European B200 directly from Huawei via this link & install it: http://download-c.huawei.com/download/downloadCenter?downloadId=68483&version=238533
Once B200 is present, if you check via Settings > Update you'll most likely be offered a Marshmallow OTA update. If not immediately or within a few days, then update manually as you tried before, again using a C432 build only.
With Marshmallow installed, you can follow one of these guides to install TWRP & root:
[Guide][Huawei P8] TWRP + Root Systemless Marshmallow Installation (GRA-L09&GRA-UL00)
Rooting and Unroot Huawei P8 [6.0] [FOR All EMUI4.0.1] all [GRA-Types]
First off
I have a vnsL31 p9lite on mm c432b160
Unlocked bootloader and frp
Can flash TWRP, can root, can unroot
Can access fastboot
I have b160 firmware and rollback package
I have b336 update and data hw eu zips
I have the Huawei update extractor
I have Revolution recovery
I have Meticulous recovery
I have EliteKernel
I have the OEM unlock code
I have c432oeminfo zip and oeminfo with a custom.bin
I have hisuite
Phone is working fine
My issue is that I can't upgrade the phone or downgrade the phone to any software at all.
Before my issue I was on b160 and upgraded successfully to b336 and used it for a long time. I then upgraded to b370 using firmware finder successfully. I then wanted to root nougat so I could uninstall some Google apps and tried the EliteKernel method, which didn't work and started going into bootloops. I then tried to downgrade to mm using the rollback package and then flashing b160 which worked successfully.
Then I tried upgrading back to nougat with firmware finder which didn't work, I had missing apps so I did the rollback method again which landed me on nrd90m testkeys. I followed a guide I can't remember to get back to c432 which didn't work either my phone then got bricked. It was stuck on bootloop and vibrated twice each time it tried to go past the Huawei logo. I couldn't access anything but fastboot. I then followed another guide to extract cust,boot,system and recovery images from the b160 update zip and flash those through ADB which worked and have my phone in working order.
My phone now shows build number as vnsl31c432b160 but model number as hi6250. I can't update the phone to nougat or reflash mm to get back to completely stock. Dload 3 buttons method doesn't work for b160 or b336, it goes to 7% then System incompatible error. Flashing the update zips through TWRP doesn't work either, I always get a zip error although it says done but nothing happens.
I want to get back to stock nougat or may even try a custom ROM as long as it is extremely stable. I am willing to root and unroot and do whatever need be to upgrade again. I think I have all the files necessary and should be able to follow any advice given
You must try flashing a OEMInfo for your model and correspondent firmware.. If you want, you can send me a PM with the details of your phone and I'll try to give you the exact files you need to use..
The model is VNS L31, it's dual sim and I'm currently on marshmallow b160 region c432, I bought it carrier unlocked. But the model number shows hi6250 now. I'll try flashing the oeminfo you give me and hopefully it works
This is what I mean, but it is a VNS L31
Hello. Finally I received the OTA Nougat update. Until now I had a perfectly working TWRP/Rooted phone on Marshmallow. Unfortunately I'm stuck now. I have a VNS-L21 Dual Sim Phone.
The update installed fine, but model number says NRD90M test keys. I'm missing a ton of the stock features, including system updater app. I'm unable to return to Marshmallow as said in this tutorial https://forum.xda-developers.com/huawei-p9lite/how-to/how-to-roll-noguat-to-mm-l31-21-c185-t3539885
(package installation failed when I try to)
What shall I do?

After converting to dual SIM you can upgrade to Nougat via TWRP, unpack B370 onto SD card, then flash update.zip file, go back to main TWRP menu and flash second file ...hw_eu.zip. Reboot system. Use TWRP 3.0.2-0 .
But converting to dual SIM may cause problems with next system updates, includÃng OTA and Firmware Finder (IMEI and infos in partition Vendor).
You can try also this solution bellow, with this method you can choose firmware, wichever you find most convenient :
https://forum.xda-developers.com/huawei-p9lite/how-to/update-p9-lite-nougat-ota-s-officials-t3661906
It works fine (self experience). Good luck!
So, due to my Pixel's battery life being atrocious I wanted to try LineageOS 14.1 and use my P9 Lite as a daily driver.
I started by downgrading to Marshmallow from Nougat as DC-Unlocker wouldn't work on 7.0 and I needed the bootloader unlock code.
( I used the firmware and tutorial from 4mobiles dot net, looks to be a polish one. )
Once on 6.0 MM I was able to get the code and unlock the bootloader, however, LineageOS and it's TWRP does not seem to work on 6.0 so I needed to upgrade to Nougat again.
Unfortunately, when I try the official update it says there are no updates available and any time I try to use the firmware finder app either the download fails or upon attempting install the phone reports a 'compatibility issue' and won't accept any firmware.
I tried loads of different update.zip files via the recovery update as well as through ADB. Nothing seems to work.
Finally I was able to get TWRP 3.0.2.0 on it, but again, only the version from 4mobiles dot net works. Other versions of TWRP just remove recovery altogether. (I guess they don't work with 6.0)
At this point it's a bit easier to try roms, but still none of 'em seem to work.
-I tried sideloading and manually installing lineageos 14.1 from the sdcard, it fails with ERROR CODE 7
(currently I'm stuck on the 'YOUR PHONE CAN NOT BE TRUSTED/BOOTLOADER UNLOCKED' screen, no splash but I can get into recovery and fastboot)
-Tried flashing boot.img and system.img of various OEM firmwares as well as LineageOS's manually through ADB, same result, bootloops
It seems to me that some other file makes the phone believe that it's incompatible with any of my roms. Maybe the firmware i got for 6.0 is region locked, or perhaps it's the vendor.img that I don't know how to flash?
I know it's a grave mistake but I didn't take a note on what my original version number was. It was the latest 7.0 Nougat EMUI 5.0 update on a UK based unlocked VNS-L21. The 6.0 MM I flashed on it with a rollback update was C900B300.
I tried the proxy method, custom DNS, and manual download on various roms in the Firmware finder app. Even when the download doesn't fail, the system always says the firmware is incompatible when I try to install.
Right now I could put 6.0 MM back on it and make it usable, but I doubt it would be much better than the 7.0 that was on it originally.
Can anyone tell me how I could put the original Nougat firmware back on it? eRecovery doesn't detect any possible updates.
Any help would be appreciated and thanks in advance!

use full update.zip from firmware finder. to upgrade, you can't use latest package. you must use first nougat update.zip.

I've only used Full-OTAs, no bugfixes. None of them seem to work.
Yesterday I tried manually selecting a different model in Firmware Finder;
VNS-L21C185 instead of the default VNS-L21C432-
and downloaded VNS-L21C185B397 update. It verified fine but I couldn't install it due to my recovery being TWRP and not the stock one. What I think I'll try is flashing the recovery of the original Marshmallow firmware that's currently on the system and seeing if it will install this update. I kinda doubt it will tho.
Any other suggestions?
Is there any way I can install a nougat TWRP without my current working firmware being on nougat?
If not, is there any way I can install a nougat firmware with TWRP 3.0.2.0? In order to flash update.zip / update.app files I need to get the stock recovery back, but I can't seem to be able to do that.
Is there any way I can flash a standard OEM Rom onto it with TWRP?

you can't install nougat TWRP in EMUI 4. you can install update.app with original recovery.
extract UPDATE.APP from update.zip
place UPDATE.APP to dload folder in sdcard.
press power button, vol+ and vol-
