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

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

I wrote an edit how I repaired my phone
hello, i'm using Huawei P9 Lite VNS-L21. i tried to flash the stock nougat Firmware Which i actually did and it worked flawless! but there was a little problem because there wasn't any Software update option in there, so after that i wanted to downgrade to stock MM. IDK what happened wrong while installing that, my phone got BRICKED. i don't have the Erecovery and twrp either. i cant flash firmware via DLOAD Method. the only thing i have is FASTBOOT mode..
i tried literally everything.. but nothing working..
I sent it to HUAWEI CUSTOMER CARE and they returned it back after a couple of days...
im really very worried because ive been using this phone for like 2 months ... and now im helplesss, If anybody is reading this please help/ assist me out of this..
first of all,notice my problem warranty check (not that message appear after logo), warranty employee check device in bootloader ,
so i can remove message with flash stock rom and recovery , and when i get info about bootloader gave me it's LOCKED , but in bootloader screen two line with red color shows Phone unlock(it's shows the phone at least one time unlocked and warranty was void) and frp unlocked.
The question is HOW TO FIX IT TO SHOW LOCKED WITH GREEN COLOR as same as device locked?
I don't think you can.
To my knowledge, the best you can do is fastboot oem relock unlock code, but that will leave you with the relocked status.
I've tried fastboot oem lock unlock code but that doesn't work.
Flash oeminfo via twrp it will LOCK not relock your bootloader and then you must use 3 buttons method to update on MM if you are on Nougat.
Flashing the stock firmware through the dload method relocks the bootloader.

You didn't flash it correctly. if for nougat update.app must be 2.5GB.
Also it wikl fully LOCK, not relock bootloader.

You need to extract the zip file from update.zip and put UPDATE.APP in dload folder. That's how I locked bootloader on nougat.

but by this method app not installed , one file for rom and another for apps,
so OK , how can i test it? now i'm in nougat ,decompress zip file and flash it with 3 buttons, OK!
what about zip app file?
how to flash this one?
or you how done it . are you upgrade from mm to N ? give me your file and tell me how to flash it,
my phone is p9 lite vns-l21 , after downgrade to mm b 160 and in N b336..
i used THIS
When you upgrade to b336.
1. Unzip update.zip you flashed
2. Create dload folder and put UPDATE.APP inside
3. Reset phone and press 3 buttons
4. EMUI will update by itself and will lock bootloader after it's done.

i done it with flash oeminfo , now bootloader is LOCKED but when i go to bootloader , shown me "" PHONE UNLOCED "",
it's my problem!!!
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.
Hello, i rooted my phone (L31C464B335) using this guide here. Now i want to install rollback then Android 6. But there is no rollblock for c464 available, i need to change oeminfo to c432. I tried flashing included in this , and SRK tool zip but i got error "invalid zip file format". Also one more thing, when i enter developer settings, settings app stops working.

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
