Messed Up Stock Rom

So I accidentally messed up my stock rom by dirty flashing, stupid of me I know.. without a backup.
Id like to know.. where can I download a stock firmware, debloated and latest if possible or if not just simply a stock firmware. Ive been trying to figure out for a day how to fix my problem but of no avail.
I use a custom recovery TWRP. Unlocked BL and rooted.
Help please

can u post a screenshot from device info ???

I have uploaded it

I can't find the b390 stock rom, but you could install the rollback package and go back to a previous build that for instance you can find here: https://www.getdroidtips.com/huawei-p9-stock-rom-firmware-collection/
And afterwards you could use the integrated updater.
But if possible oem unlock it first to save you from possible bricking. (oem lock restricts fastboot commands).

Reverto to stock after root and custom Rom

Hi all. I would like to revert the phone to stock after root and custom rom. Ther's a guide? I can't find anything on the forum. Thanks at all.

I think you just flash the stock firmware over what you have.

Thank's! So, no warry bout unlocked bootloader?

You might want to relock it first, but I don't think it matters. I am not sure though. Just basing this off my time with the S3 and S4 back in the day. With those phones it didn't matter. The S10 line are newer so it might with them.

I presume you want the boot screens to revert to normal without the Bootloader Unlocked warning screen.
If so, see my post HERE

I am on lineage os (Ivan_Meler) not rooted
under the developer there is no OEM option showing. My bootloader is unlocked, recovery is TWRP.
how can i goo back to stock ?

Just to be sure: Before I flash a custom firmware on a S10(+,e) like lineage, there is nothing to back up like DRM keys or certificates? (I had SONY phones before. If you reverted to stock on those some SONY apps would not work anymore if you did not backup the DRM keys).

Hello guys,
Similar question what is the procedure when I want S10e with flashed custom rom (TWRP Recovery), rooted and unlocked bootloader to return to stock firmware?

How to revert back to stock on Nokia 8

I have a Nokia 8 and it has an unlocked bootloader, TWRP and magisk installed. I'm planning to give it to someone and I want to revert back to stock. The problem I'm facing is that my bootloader is not critical unlocked and I lost the unlock key. How do I go about flashing stock image. I'd also like a link to the stock ROM cos I can't find one
Thanks!

Question Rom 12.5.5.0 RKDEUVF

I have the Rom from Vodafone which however does not receive updates. Would it be possible to install the standard European ROM RKDEUXM without unlocking the bootloader and without losing the phone configuration?
I have the full rom file for fastboot installation 12.5.19.0.
Really thanks

Unfortunately, no, without losing configuration and data, you wont be able to flash any other version roms.

1. It's impossible to flash different rom without unlocking bootloader.
2. It's impossible to unlock bootloader without wiping the phone.

I see that is possible for Xiaomi phone using XiaomiTool V2 via ADB (debug usb enable).
You loose data but you don't have to unlock bootloader.
I don't know if it works with 11t pro...

I'd say DON'T DO IT. Switching ROM like that without unlocking the bootloader is a very bad idea. If something goes wrong your recovery options will be very limited. For sure though if you don't format data after flashing a different region ROM the device will end up soft bricked. Either a bootloop or perma fastboot mode. Adb doesn't work with stock recovery and stock recovery doesn't offer the "format data" option anymore just "wipe" which is not the same and won't fix anything. So unlock bootloader first.

Thanks!
But is it possible to re-lock after rom installed and is it possible to have ota regular updates?

You can only relock bootloader when the rom installed in your phone is the stock ROM came with your phone or else you'll brick it and have to reflash in EDL mode using test point.

Now I'm with RKDEUXM Rom...no brand Vodafone.
I've closed bootloader After flash and small test.
All work fine, no brick and Ota updates downloaded and installed.
Thanks!!!

Question Question about flashing stock rom

Can I reflash back the stock rom even if the bootloader is locked?
I ask because I know it's possible with my Samsung Galaxy S6. Not sure about Xiaomi phones.

You have to unlock bootloader first to flash stock rom or any custom rom.
