Going back to stock ROM after installing a custom one - HTC U Ultra Questions & Answers

Hi guys!
I've installed a custom ROM on my device and now I want to switch back to the stock ROM, I don't have a nandroid backup, what can I do? I've tried some RUU's but when I boot in Download Mode, it doesn't read anything.
Please help me

Just do a clean install (wipe internal memory also) and install the ruu
Also you can find multiple ruu files from the link thread below
https://www.google.com/amp/s/forum....-htc-ultra-dual-sim-1-64-400-10-t3758077/amp/
Hope this works..
Gdlk?

So your phone have 8.0 firmware. If you want stock 8.0, just enter my post from link below and download stock zip flash by TWRP. If you want stock RUU, you need follow DOWNGRADE to Nougat post.

I forgot, your CID can not use my rom. You must downgrade to nougat. because no one have 8.0 RUU.

I would install Nougat too, I just want the stock ROM..

Your CID is rare for single sim variant
First you need a Ruu for ur specific CID
then the rest of the steps are pretty much the same.

I should download a Nougat RUU for the 034 CID, right? Then when I put it in the sd and boot the phone in download mode it should install it, because I've it and it doesn't do anything, and the RUU seems good

from your post with the RUU's, I should download the first file from AndroidFileHost right? The CID_001__034 one

When I change the version with HTC Version Tool, I write 1.64.401.1 wich is the RUU's version, when I boot in download mode near OS it still shows 2.21.401.1 and it still doesn't read the RUU...

I can probably see right now, you've done it wrong... Download stock rom from huawei.consumer... For some reason i thought it's gonna be android MM, but it was android N, so no problem here, just download stock rom and you will have newest android.
You probably downloader rom from xda, rom it's in .zip right? And you tried to flash it with TWRP?

Yesterday I had this issue, it's more easy than it seems. In Revolution Recovery for Nougat, flash the update.app ZIP with 6.0 , it will show you a lot of errors, but don't worry, it's ok. After this flash than DUALSIMOEM.zip and after that shutdown your phone and use the 3 buttons method to automatically ,,update" to B161.

That's because u don t have the bootloader unlocked Also, verify in Developer Options to have Enable OEM on, that's why you have an error in CMD

If you have unlocked boot loader, you can flash official firmware in TWRP recovery by following this guide https://forum.xda-developers.com/honor-4x/how-to/install-emui-4-1-4x-4c-g-play-g-play-t3515702
And btw if you want you can download newest firmware for your phone it is B572 it think.

I don't think you can flash latest firmware directly if you're still running lolipop.
But if you want custom roms, then just get twrp recovery and flash a rom.
There's no need to upgrade stock firmware to do that.

I am on Oreo stable 8.0.0.322 but the rom is very buggy and a battery hog.
I would like to revert to Nougat. Would this method work for me as well?
Also, why do I need to flash recovery, wouldn't the existing recovery work?
