Hello everyone, I'm a bit of a noob so bare with me. Thanks for taking the time to hear me out.

I have a sim unlocked AT&T HTC One (M7) that I am using on T-mobiles network. I switched over last year and I don't have my AT&T account anymore. The phone is stock, not rooted at all, just sim unlocked.

I have not updated the HTC one at all since I've bought it, and I would like to update to 4.2.2 KitKat but I noticed I cannot update via T-Mobiles network. Help!!!!

P.S. Is there a way for me to update my phone manually without having to find someone with an AT&T sim card?

Updates are usually done over wifi rather than the current network, being on T-Mobile should have no effect on the updates. What happens when you check for updates.

Im in Mexico and I have the same problem..

HTC unlocked.. no update via OTA.. looks like ATT punished all the unlocked phones with no-sending the update.

I can't update the phone,

no via OTA
no via ROM
no via adb push rom.zip (access denied)

no nothing..

Hey mb_guy, thanks for the reply.

When I am connected to wifi or 4G-LTE and try to update via settings-->about-->software updates nothing happens. It doesn't even try to search for new updates. Another interesting thing is that when I try to search for updates on the phone, I see AT&T even though I have switched over to T-Mobile and am using the T-Mobile Sim Card.

P.S. I did pay for a sim unlock code from a website, could that be the reason why I am unable to update my phone?

You can update it yourself with this RUU and a locked bootloader

Hello. Another newbie here. Could you post directions on how to use the above file? Do I need a PC, or is there some way copy the the directly onto my HTC One.

I have the same problem as the OP. I have a SIM unlocked AT&T HTC One that is stock with a locked boot loader. I have a prepaid AT&T SIM. But I cannot get the OTA update. I've tried several times to get the KitKat update, but each time it says no update available.

the RUU is a windows EXE file just click it and follow the instructions
Back up your phone ! a RUU totally wipes everything from the phone

Actually when I try to update via ruu, I got an error.. fastboot.exe in windows.. and the installer shows in the messages in: checking header 1/5….

If I disconnect the cellphone.. There is an error with invalid copy or something like that..

A few days ago I tried with adb push rom.zip and I got an error with: permission denied (when I was trying to copy the rom to media/0/ etc..

Im starting to think that the problem is the "memory or storage" because I guess all the problems or the methods stuck trying to copy the files or something like that..

I stuck with all the methods basically :S

OK I've tried running the RUU from two different computers. One computer was running Windows XP and the other was running Windows 7. Each time I get to the point where the set-up wizard asks me to accept the license agreement. When I click on the "I accept" radial button and then click on next, the set-up wizard just shuts down.

I've tried it three times on the computer running Windows XP. On the third attempt I had the Task Manager running and the process just stops and disappears.

Can anyone offer any help.

I read on another forum that replacing the SIM card can help. So I went to my locate AT&T corporate store and got a new SIM card. No luck with that either.

I purchased this phone used It is in great shape. It looks new. It is running Build Number 3.17.502.3 CL246232 release-keys.

Because I bought a used phone, I just downloaded Connectbot and verified that the phone was not rooted.

It's looks like you have HTC sync installed? If so, uninstall it and try the ruu again.

I unninstalled the htc sync and restart the pc.. but same problem

The phone is s-on, correct? Is the bootloader locked?

That's correct.

when the error appears.. (fastboot.exe) the screen in black with HTC then if I disconnect the cellphone this is the error.. then I have to plug again and push power button until the phone restart again normally.

thank you so much for your help.

    SUCCESS!!!!!

    cschmitt - thank you for your offer, but I was able to get the OTA update. I'm now running Android 4.4.2 and Sense 5.5.

    It wasn't as satsifying as fixing the problem myself, but I ended up calling AT&T Wireless tech support for help.

    I have an HTC One 64 GB AT&T Wireless model and an active prepaid GoPhone SIM card. I did a carrier unlock on it using my wife's post-paid account really for no other reason other than I could. My intent is to use this phone as part of my employer's B.Y.O.D. program which requires an unrooted device for security purposes.

    Any how, I called AT&T Wireless tech support and after some prodding to get them to accept the fact that I didn't have the latest firmware on my phone, they called HTC's tech support. The HTC tech support rep had me boot my phone into Safe Mode and I was able to download the update without incident after that.

    Thank you again and this is a great forum. I hope to learn a lot here and hopefully one day give something back.
