Have you looked for 'downgrade nokia lumia 800' on google? On the cabsender topic page there are a collection of cabs available. Don't know if it's possible to write them back one way or another. If you find the solution keep us posted. I'm trying to get rid of the singaporian update to get my own dutch official firmware working, and I to did not make a backup of the phone

[Q] Restore Lumia 710

Maybe it is a stupid question and if so, I apologize for this.
I bought a Lumia 710 and I want to interop-unlock it. Just checked for every thread in the forum but I don't have found anything that fits to me.
If I follow one of the guide in the forum, I flash my phone and everything goes ok.
When I want to return to stock ROM (example for warranty), what are the steps to follow?
very thanks to everyone!
I would imagine you'd need to download the stock ROM from NaviFirm and flash it with either Nokia Care Suite for DLOAD bootloader or for QC bootloader there is another program you need to use, but I can't find the name of it.
All info is here, just read everything
And this is what I thinked about, but I want a confirm.
The version I have of NCS Product Support Tool is 2012.12.5.3 in normal mode found my phone, but in QC bootloader don't find it.
If i wish to restore original rom, there is a guide for it?
yes, you use NSS to restore your bootloader. check it out in development thread and say THANKS to the Developer because he has mede it easy to use.
Cheers
Use the NSS Suite to get back the Nokia DLOAD then just update normally to get back to the original state for your warranty claims

Ok, thanks to all, for now I don't have necessity to claim for warranty, but you know, Fortune is blind but bad luck sees us well!!!

REVISION FM. 1750.0805.8773.12220

Try with Nokia Care Suite if update is not available there for your firmware..u can try another firm from Navifirm+.
If the phone has been unlocked via an unlock code make sure you have that code before flashing a new firmware-- it will re-lock the phone.

Lumia 920 Firmware Flash

Hello,
I am new on the site and thank you in advance for all your help. My problem is this:
I bought Lumia 920 in USA in AT&T. It was unlocked phone to work with any SIM card. I have noticed that I do not have 4g speed on my phone and I do have carrier which supports 4g. Now I see in other topics that I have wrong rom. It is for USA. My current Rom is rm-820 and I see that I need rm-821. Ok, thats fine I can flash my phone and it should work. But, every topic, every page that I found on Google doesn't work. To be more precise topics do work but I can't get rm-821 :-/ I saw that Nokia blocked those servers something like that. Can someone give a me a way to put rom but technique that works ? I am from Croatia if this matters for rom.
Thank you very much guys !

ATT Lumia 920 Firmware Flash
Hi,
I might have missed some methods to do this task but in trying to debrand an ATT lumia 920 (RM-820) that's fully updated to WP 8.1, I can't seem to find a successful way to do it. I've done this procedure in the past successfully by flashing the specified Rogers firmware to the phone with Nokia Care Suite then on to an RM-821 firmware but what worked in the past no longer works. Nokia Care Suite now gives me an error message that the FFU file from my flash file and the FFU file on the phone don't match and the flash procedure halts. I've tried several different Rogers firmware files and no luck with any of them. Any ideas how I can accomplish this task?
