How to return stock with hboot 1.57?

[tswfootball]

Hi!

I'll start off by saying I'm from Sweden, so I'll write this post in english and hope it's fine.

I have an HTC One with CID T-MOB101 that's on firmware 4.20.111.21 and hboot 1.57.
I then used the custom rom ARHD 71.1 for a while, and now that Sesne 6 has begun rolling out to the T-MOB101 phones I would like to go back to using stock..

I tried using the Guru Reset:
htc1guru.com/dld/guru_reset_m7_2-24-111-3-zip/

But ended up getting a bootloop after installing the android 4.3 sense 5.5 OTA update.. I then realized that this was so, because I'm on hboot 1.57 and that's why it messed up(Because the guru reset and sense 5.5 was on hboot 1.55)..

After googling around for a while I found that this site had a nandroid backup for firmware 3.63.111.3. I know that this firmware version also has hboot 1.55, but I decided to try it anyways.. So I flashed the backup and now have a phone with Android 4.3 and Sense 5.5 and firmware 3.63.111.3(I couldn't find a stock recovery for 3.63.111.3 so I'm running the recovery for 2.24.11.3). The bootloader still says 4.20.111.21 but on the "About phone" page it says 3.63.111.3

I then got a prompt to install a OTA update for firmware 4.20.111.21 and downloaded it. However installing the OTA update failed as I got the error message:

"Check: /data/preload/TMI_MobileTV_at.apk failt. error no such file or directory"

.

I'm not sure what that means but I'm assuming because I have hboot 1.57 that's the reason why it's not working properly..

So now to the help..
After googling around for a while I've realized that this site has most of the files for HTC One phones with CID t-mob101..

Are there any nandroid backups for firmware 4.20.111.21?

By searching I've found these posts:

This one has the OTA file for 4.20.111.21:

And this post has the stock recovery for 4.20.111.21:
https://www.android-hilfe.de/forum/...ck-recoveries.502478-page-2.html#post-7769393


Is there any nandroid backup for 4.20.111.21 so I can flash it and get the Sense 6 OTA update..?

I'm sorry if this post went on for too long, but I've been searching for hours in my attempt to take my HTC One back to stock.. I'm starting to fear it is impossible

No, there is no backup online this time, sorry. We´ve searched for it also in some threads. The only way at the moment is to try to get S-Off and downgrade with the guru reset rom or you change the cid and flash (also with S-Off) the stock HTC-RUU and the following updates. With S-On you have only the choice to flash a custom Rom.

Ok thx for reply..! Hopefully it'll be available soon..

As of now I'm not able to gain S-off.. I always get the "whelp" message on firewater :/

Yes, it´s more difficult to get S-Off with a t-mobile device. I wish you the best.

Hi and welcome tswfootball!

I'm sorry, but the only language allowed in this forum is German.

I'm closing your thread now. You can open up a new one, if you want to translate your text into German.
