Why i cannot update to Windows Phone 8.1 GDR1 Lumia 1020

Hello all, first i bought the phone in restart loop. I fixed it by flashing older rom with Phone Image Designer. It boots when i am using older rom but when i try to update to 8.1 GDR1 my Lumia is again stuck in restart loop. Tried hard reset and it doesn't help. The phone is AT&T so i cannot try flashing another image than AT&T image. In my country there is no Nokia Care store and no AT&T and I don't have AT&T sim can this be a problem? Thank you

Okay just making sure one last time before I rule this as a hardware problem...

1) Nokia Product Support Tool 5.0 in offline mode
2) Uncheck "Automatic product selection" and click open product and select RM-877
3) Click on Programming >> Recovery, here you'll find your downloaded firmware
4) Click start and let it verify the firmware then connect your powered-off phone while pressing volume-down and click start after vibrate to flash (red bar)

You did perform the exact steps right?

The reason I ask is this process has always solved all software glitches for me, unless its a hardware failure

Rather than using "Phone Image Designer", you may want to try using the Windows Phone Recovery Tool to re-install the appropriate OS for your L1020.

​The problem is not there; he may very well use WPID (Windows Phone Image Designer) as long as he has access at the MSFT FFU DL Mode.

I did everyhing the same as told except unchecking "Automatic product selection" is this important?

MSFT FFU DL Mode

What this means? Thank you all
EDIT: Is there something i can check my product code on hardware not software side?

I don't think so, i usually uncheck it if I'm flashing cross variant firmware. Having said that, I'm out of options here :-/

I really don't know where is the problem. Is there somewhere on physical parts where can i check what Product code my phone has? Thank you

I fixed it. I downloaded latest denim update using navifirm+ then i flashed using Nokia Product Support Tool 5.0 and i've got the reboot again. After that i done hard reset that haven't helped neither and again i reflashed same image using Phone Image Designer and voila the phone booted and i came to select language menu. The phone works flawlessly again with latest Denim update and i'm sure updating it to Windows 10. Thank you all, best wishes
EDIT: Cyan update

Nice dude. Glad it worked out. My heart woulda sunk a little otherwise, I know how bad it sucks when your device is bricked.
