[Windows Central Question]

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

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.

I have tried that but nothing seems to work except the older software. I am now downloading the latest software via Windows Phone Recovery tool and try if I stuck again i will write here again. Thank you all best

[gpobernardo]

Alright, let us know what happens.

Again stuck at reboot loop. It seems I need some more help :D

The phone reboots after Nokia logo i can't even reach Windows logo, already tried Hard Reset

I am not sure how we can help more.
All the attempts you tried failed so it really looks like a hardware problem.

Anyhow good luck.

But maybe if updating to 8.1 does not work you could try to use developer preview to get the OS functions from wp8.1

Search for instructions on how to perform "dead flash" using Nokia Product Support Tool. That should definitely work unless its a hardware problem

Thank you, first i tried using Developers preview it asked me to update the regular way i think this is because i need more recent software then it comes to developers preview software. I can start the phone on older software and it's working good on Amber update. When on Black update the phone stuck a lot and i need to perform soft reset in order to work again. I don't think that it's hardware problem because on Amber the phone works flawlessly. I have tried dead flash and that's not working either.

Can you elaborate where/which step didn't work?

Update successfull, the phone reboots and after Nokia logo when it should come windows logo it reboots again and again. Sometimes it comes to Windows logo and again reboot.

And when you say update, you mean flashing the phone ROM? And you get a red screen while flashing, correct?

[sini6a]

No i tried updating via OTA and everything goes well and when the update finishes it infinite reboots. Also I tried using Lumia recovery tool it completes successfull too with green light but again infinite reboot.

That's what I thought. So you haven't performed "dead flash" and yet you mentioned you already tried it. Check out some videos and have some patience when performing it, should definitely work.

You mean dead flash using Jtag or those kind of boxes or could you explain me little more. Thank you
EDIT: I found with Nokia software update for Retail, i think i used this once with dead flash, but i will try again and report.

Use Nokia Product Support Tool for Store 5.0.

Unsuccessfull, did exactly as tutorial said. Reboot loop again...

So you flashed your phone this time? What product code did you use?

[sini6a]

I am flashing this phone almost 3 days...
It's AT&T RM-877 so i used 059T019

[pankaj981]

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

​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?

[pankaj981]

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 :-/

[sini6a]

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
