Please help: How to return htc u11 to stock

[dsymbol]

Hi guys,
My phone now is on LeeDroid custom ROM (Build 1.03.401.6.9_g CL923215)
What are the steps to return the htc u11 to stock please?
The original software number of my phone is: 1.11.400.4

EDIT: I went to: https://forum.xda-developers.com/showpost.php?p=72425224&postcount=5
& downloaded stock recovery & nandroid TWRP backup (for 1.11.400.4).
However, I couldnt flash that nandroid TWRP from TWRP recovery.

Long story short, I just got the phone today, I made a big mistake by not inserting the simcard in & testing to see if the phone working or not.
So, I went straight through the process of unlocking bootloader, installing TWRP, Rooting, Installing custom ROM without making a nandroid backup.
For all that, the phone did not recognize the sim cards (tried both my sim & my gf's sim. not working)

The store will take back the phone as long as I return it to stock.

Thanks for your help!!!

Googling doesn't give me much result.

You'll need to download the stock rom for your verison (ruu). Hopefully one is available. Check the guide section here.

Restore the TWRP backup, check everything is working, then flash stock recovery if you need to. The stock Nandroid should include recovery asfaik. I'm more of a trial and error guy lol. Read guide pages to know for certain, check HTC 10 guides, same steps.

ok so I downloaded TWRP_Backup_Untouched_System_Image_+_Boot_1.11.400.4_OCEAN_DUGL_with_recovery.

1. Transfering the TWRP backup to the phone's storage
2. Flashing that backup just like flashing the custom ROM (it says Invalid zip file format. Error ect...) Please help
3. Flashing the recovery just like flashing the TWRP using adb commands
4. Lock the bootloader? I don't know how to do this.

Please advice
Thanks purple patch

download this Official RRU firmware and install it https://forum.xda-developers.com/u11/how-to/unlocked-htc-u11-software-update-6-19-t3624814

Use the ruu, you might need the HTC drivers but in the future never not make a backup, 15 mins could save u a major headache

Finished downloading & now I got an ERROR installation, something like a wrong ROM, probably because I'm currently on LeeDroid custom ROM (Build 1.03.401.6.9_g CL923215)

Please advice
Thank you

Your going to need a full signed RUU zip matching your original firmware and CID buddy.

Based on your original build number its an Indian dual SIM device so here is the ruu:

https://www.androidfilehost.com/?fid=817550096634780026

1. Rename it to 2PZCIMG.zip
2. Lock your bootloader
3. Drop the zip on your external SD card.
3. Boot to download mode, at that point you will be prompted to flash... Accept... Profit.

If you don't have an external SD.

1. Lock your bootloader.
2. Boot to download mode.
3. Open a cmd window and run the below commands.

fastboot orm rebootRUU (hit enter)

fastboot flash zip (drag the zip into the cmd window then hit enter)

On the PC side, what was the exact error message?

you can ignore the warning from the phone side.


I had a similar issue the other day, but then I was able to run the RUU upgrade to rest my phone back to stock as I had to ship it back for a refund, to get the new Red ones

When I ran the RUU thing it wouldn't detect the phone, did a few things, and then it was finally able to detect the phone.

and when it started updating the Boot image it hung for a long while, I had to restart the phone back into download mode, then run the RUU again, and it was able to continue from there.

The 1.03.401.6 may be European software. You will need the RUU for your exact phone model from: http://www.htc.com/us/support/updates.aspx
