Like the title already says, I wrongly flashed the oeminfo of the L21 C432 on my L31 .
Now when I want to rewrite the oeminfo via fastboot I have no access because there is a FRP lock (Bootloader unlocked).
Currently I only see two options:
1. Try to flash a firmware via dload (tried some already, not working) and then flash the original oeminfo again. But is the firmware of a L21 even runnable on the L31?
2. Use DC-Unlock. The question is what should I use there? Is flashing a completely new firmware also overwriting the bad oeminfo? I don´t think so. Or should I remove the FRP lock, flash a new oeminfo and hope that dload is working then?
I hope someone can help me. Such a stupid mistake is just so frustrating, didn´t happen to me in all the years of flashing phones
you can try the dload method using a L21 firmware...

did you ever manage to fix this? I'm stuck in the same loop except my frp is unlocked but my bootloader is locked (Shows in the fastboot white screen mode) I tried to flash via dload method everything from B150 till B380! I was running Nougat rooted and I wanted to downgrade back to MM via flashing oem from twrp but I messed things up!
i cant even dload firstly because i have twrp and 2nd my phone goes stright to erecovery and i cannot find a way to either flash my oem info from twrp back up on my pc or to get new firmware.

Device: VNS-L21 Europe Hello, before brick I was on new emui 5.0 firmware and I installed nougat twrp recovery by user @BadWolfYe and then I flashed this rom: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493 (I was following all instructions) After reboot It was stuck on Phone is booting... And I tried downgrade guide from this thread: https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932 I flashed oeminfo zip and dloaded update.app but unfornately zip where I get update.app was corrupted..... Now I have only Huawei eRecovery, dload and fastboot but It doesn't allow installing twrp!!! When I dload UPDATE.APP It says Software install failed. Failed to check the update package. Please download the package again. Please help me!!!!!!
EDIT: I found solution to enter in real recovery(TWRP for nougat)
What I did was:
1. Enter in fastboot
2. connect phone to computer
3. open cmd and type: fastboot -i 0x0fce oem unlock xxxxxxxx (replace xxx with your code)
4. accept fastboot unlock
5. And then it magicaly booted into twrp (my phone's fastboot was unlocked before)
Now I am going to flash back emui 5.0
And then downgrade to emui 4.1
And then I will try to install this: https://forum.xda-developers.com/huawei-p9lite/development/unofficial-huawei-p9-lite-t3540493
Later I will update this post and I will write does it suceed or fail.
Edit 2:
I flashed emui 5.0 with dload and UPDATE.APP

Flashing oeminfo locks the bootloader. Did you unlock it again afterwards?

You need this file, flash it on TWRP and then you should roll back with a stock rom
@Jinclaudio
i flashed it, but now bootlader is locked, and i can't boot my phone. when i start huawei erecovery thing appears...
Excuse me for late. You need unlock the bootloader again, because flashing oeminfo will relock it
My original P9 lite is VNS-L22C635 , it japan version, unlocked bootloader, twrp, and changed oeminfo to L21C432.
Now, my device can update succesful firmware C432 by dload method, but when it done and restart, it stuck on Huawei device animation. I tried every way, even change Oem to C636 and dload, still stuck huawei logo. Not boot to system.
I think i flashed wrong firmware, even changed device to another oem. Can anybody share me C635 oeminfo, i can not find one on interner. . May be after change oeminfo to original, and dload firmware, it can live again. Maybe, i not sure !
Please help me. Thanks
Unlock bootloader and try flashing via fastboot. Fastboot flash boot boot.img
...system.img...recovery.img
(Must unpack UPDATE.APP)
any one help me my phone cant inter to twrp (remote: partition length get error) ) or erecovery and cant update with dload sdcard and cant flash it with fastboot and stay at dead screan and reboot
plz help me
The 1st thing you will need to do on any locked device is to unlock the Bootloader before you continue.
To unlock Bootloader you will need to use any of the Huawei paid services in order to do so.
Several are available for that and will need to check for that online.

i flhashed it with this method after they dead

Try different Firmware. Sometimes there is a problem with that. Try to search for others that are good as well.
