Root [AT&T] Issues with software on HTC One.

[mxracer591]

A few months ago, I got an error on my phone "android.process.acore has stopped" It wouldn't stop no matter what I did, I tried cleaning all the temporary memory, I even formatted my phone. So, I took it to an att place to see what they could do. After 3 or so hours of waiting, they finally got it to work... sort of. They installed some sort of custom rom on it. When I go into bootloader, it says 'tampered' and 'unlocked' For the most part, I don't have an issue but I would like to install the android software update. Whenever I try to, it just goes into the custom rom's screen and I really can't figure out how to install it. Is there anyway I can just go back to having a normal phone, with the update?

Go to an AT&T Device Support Center (if your store isn't one, they'll tell you where the nearest one is) and tell them that looking up the phone's history will be a lot faster than your explaining what happened. Once they do, ask if you can have a normal phone that can be updated when updates come out.

The only problem I think would happen with that is that I bought it from Ebay, it was new in the sealed box... so I would like to assume that there shouldn't be any pre-existing issues with it, but of course there's really no way to tell. It ran fine for about 6 months after I bought it until this issue happened.

wait,what? at&t employees unlocked your phone and installed a custom rom?

i personally would recomend getting s off. at that point,its easy to get back to a working phone that will get real OTA updates.

you will need to use rum runner or firewater to get s off.

firewater s-off

since youre unlocked and rooted,either should be fairly straight forward

some info about your phone may help us also,if you can do this(xx out imei,meid,esn):

Spoiler

first download and install these drivers: revolutionary drivers (mirror)

then,download this small file:
mini-adb.zip

-unzip it,and place the unzipped folder onto the root of your C drive(not inside a folder)

-open a cmd window(with win 7,click start bubble,type "command" or "cmd" in hte search box)

-now change to your mini-adb directory(assuming you didnt chagne the name). type in the black cmd window that opened on your PC:
cd c:\mini-adb

-pull the battery in your phone for a few seconds. hold volume down,then power. hold them both until you see the white/colored writing hboot screen

-select "fastboot" from the hboot menu with the vol rocker/power button

-in your cmd window type:
fastboot devices

it should output your phones serial number. if so youre good to go. if not,youre apparently having a driver issue. i usually recomend these drivers from Revolutionary: modified htc drivers download and install the drivers(you should just have to run that file). afterwards,unplug your phone,plug it back in. make sure its in fastboot. as soon as you get a result from "fastboot devices" your ready to procede to the next step.

-in your cmd window,type(or copy/paste,is much easier):
fastboot getvar all

-copy the info that outputs here. right click in your cmd window,click mark,highlight it all in white. hit enter. paste the info here. it will help us know which ruu for you to run.

Does the screen it goes into on reboot say TWRP or CWM?

If so, then go find htcguru's stock ROM download, and you can use that to go back to 100% factory
