trying to return to stock for upgrade

ryche316 · Apr 5, 2014

I have been stuck for days now trying to get my HTC ONE on AT&T back to stock so I can upgrade to KitKat
I am at the point where I got the bootloader relocked and I'm trying to install the RUU zip. Everytime I try to install it I get an error saying signature failure. I thought I may have been using the incorrect RUU file and have tried several both zip files and exe files and no luck. (phone is at a black screen with the HTC logo going across it ) also I am unable to access CWM

I am running a stock 4.1.2 HTC sense 5.0 software number 1.26.502.12

Try this file
http://www.androidruu.com/getdownlo....20_10.40.1150.04_release_326691_signed_2.exe

followed by s-off with Rumrunner
then flash this RUU..
http://www.htc1guru.com/dld/ruu_m7_...3_10-38j-1157-04_release_334235_signed_2-exe/

you should get the kitkat OTA after that

OK I downloaded all the necessary files from the links ( thank you )
I went to install the exe from the 1st link and it goes through all the motions but then I get a message saying ERROR {155} UNKNOWN ERROR The ROM Update Utility cannot update your Android Phone Please get the correct ROM update utility and try again

The you don't have the Android version you listed or your bootloader is not locked

Android version is correct I double checked. I will recheck the bootloader. Hopefully that is it :good:

I rechecked the bootloader and it was unlocked, not sure how it got unlocked again, but I relocked it. I ran the ROM upgrade and it went through with no problems. I ran rumrunner and it failed after the 2nd test and said device is not rooted, and the last exe file launches and throws up an error right away. I tried an OTA and it says no updates
I went back into the bootloader and it says relocked and the tamper is gone, so progress was made
I can get into the stock recovery mode. I select apply from phone storage ( where kitkat zip is located ) but then the phone reboots instead of giving me a menu to scroll through so I can select the KitKat zip file.
