Carrier unlock question - AT&T HTC One (M7)

I have CM 10.1 installed and bought a unlock code off eBay and tried entering in the code and it said unlock was unsuccessful or something along those lines..
Will the unlock work while on a custom ROM? The person on eBay that I bought it off sent me the code via email so I assume if they send you the unlock code its the right one and if they couldn't get the right code then they just don't send you one I assume ?

Same problem here. My code wouldn't work on CM, so I flashed a stock based rom and the unlock code worked fine.

So if I flash stock ROM and unlock it will the unlock stick if I go back to CM?
I wonder if once the Google edition ROM gets pushed out and I flash that if the unlock will work on that?
Have a link to the stock ROM though?

Yes, unlock will persist. Check the development section, plenty of stock ROMs to choose from there. Just do a nandroid of CM then restore it after unlock.

[Q] Carrier Unlock Help AT&T

Hey,
I need some help, I want to unlock my AT&T HTC One. I already have the unlock code with me.
But Right now I am on a custom ROM, GPE 4.3. I was inquisitive of two things:
1. If I can unlock my phone from the network while being on Custom ROM?
2. Can I unlock it using an international SIM, which is not working since the roaming is disabled.
To add to the first point, if I can how do I do it? And If I cannot think, I know the method to come to stock. But then again, after I come back to stock, how do I unlock the boot loader again and root the device?
Any help will be highly appreciated. Please let me know as soon as possible, I need to travel soon
I had problems SIM unlocking my AT&T HTC One with GPE conversion as well. It wouldn't unlock at all.
I simply just flashed ViperOne rom and tried the unlock it and it worked. I think you can only unlock with a sense rom but I am no developer so I wouldn't know for sure.
All you have to do is put the other SIM card with the sense rom and the option to unlock with an unlock code should come up and work.

This is a known issue that you can only unlock using a sense rom

I know it may be out of context but I have a sim unlocked AT&T HTC One, so if I'm going to unlock bootloader, root and flash a custom ROM then are there chances that my phone will be SIM Locked again ?

Unlock Codes with custom ROM?

Ok so I sold my HTC One to a friend they then went and bought a unlock code and it didn't seem to work, so then they bought another one and it didn't work either. I had rooted it and installed the Trickdroid 11 rom for HTC One with the AT&T option so would this be the cause?
If so how do I get it back to a stock rom that will work for their unlock?
Thanks!

you will have to flash back to stock for the unlock code to work. I dont understand why, but that is how it is. I had a custom rom as well and the unlock code that was provided by AT&T itself did not work, once i flashed back to stock using the RUU, the code worked as designed.
go to factory stock , i had the same issue when at&t gave me the unlock code , it didn't work while i was on custom rom , then my dumb a** actually thought it was the wrong code and got one on ebay, turned out to be the same code ....so i followed directions and went to stock , and viola Unlocked...
Does the phone stay unlocked if you flash back to a custom rom afterwards?

[Q] Problem completing AT&T issued SIM unlock

I recently converted by AT&T version to a Google Edition via S-OFF, CID change and Google 4.4 RUU.
AT&T has tried to issue me unlock codes twice, but neither works. I'm using an old t-mobile SIM to attempt the unlock.
Does anyone know if maybe updating the CID impacts the ability to use a carrier unlock code?

Install a stock at&t ROM and try again. In multiple threads it has been said that the at&t unlock code only works on stock roms

I just unlocked on a att stock rom, 4.3 to be exact. Then restored.

Proper Conditions for Network Unlock?

I am trying to perform a carrier unlock on my AT&T HTC One so I can use it overseas while I am travelling. I have contacted AT&T and am waiting for an unlock code. In the mean time, I understand I need to be on a stock ROM for the unlock code to work. I have the ROM downloading, but am curious if I need to return the phone completely to stock. My phone is rooted and S-Off - do I need to reverse both of these conditions? I'm also wondering if I need to be on a stock recovery or not.
Thanks!
Josh
It appears that AT&T will not provide an unlock code unless you are out of contract, so it's pointless after all.

I was able to obtain an unlock code from option 5 in this thread:

Loaded a stock ROM, but kept the bootloader unlocked and my custom recovery. Unlock code worked just fine.

Unlocking with unlock code from ATT

I have got unlock code from ATT to unlock my device to use the phone out side ATT network. Right now I am on lollipop ROM and when I insert a different sim and enter the code it says cannot unlock.
Do I need to be on stock rom to use the unlock code?
TIA.

Yes, you need to unlock the device with the stock rom installed.

Do you suggest any in particular?
rooted stock rom should be fine right?

I don't know your particular setup but if you are on AT&T then use clsA's Stock Rom Reset.

I had ARHD downloaded on my phone, so installed it and successfully unlocked my phone. So root doesnt matter for applying unlock code.
Thanks for guiding me correctly..

A little bit late to all this I just got the M7 . I did not think to unlock before flashing and rooting. So in order to unlock the carrier restriction I have to be back on stock and then enter the code that AT&T gives me?
