Hi everyone,
I recently flashed my Lumia 800 with the chineese version of Tango (Firmware version 1750.0805.8773.12140) and everything went fine, but I am wiling to downgrade to install the last official firmware available in my country, the 12072 one.
Can you tell me if it's possible to downgrade (my Lumia is branded and until now i don't find a way to unbrand it), and tell me if this downgrade will have an effect on the future upgrade process. Thank you for any help.
Use Nokia Care Suite. Pick the disered firmware from Navifirm+.

I just had my Lumia 800 unsimlocked officialy by my operator (Orange France) this morning, after receiving a code. My phone now works with different micro-sim, as I wanted. I am a beginner with the Lumia so forgive my stupid question please: now that my mobile is desimlocked, do I have to consider it unbranded? Is it the same? Next time I will make a firmware update through Zune, will it detect this fact and install me an "non-branded" rom?
Thanks for your answers.
I love this forum, so usefull:silly:

You need to download NaviFirmEx_v1_6_1_en so you can pick which Lumia 710 firmware you want to install. You also need to download nokia care suit to install the firmware on to your lumia 710. Its very easy to do but it will reset your phone doing it this way.
Hi guys first of all happy new year to all of you.
I'm new here, I always had a Samsung, but now I bought a Nokia Lumia 800.
Which is the best firmware I can use on my phone? I have now Windows 7.5 , provider; cv be v5
os; 7.10.8773.98
REVISION FM. 1750.0805.8773.12220
Which tutorial & tool I can best use to get my phone working well?
It no simlocked and I am from Belgium, dutch will be cool to have, but not necessary.
Kind regards,
Konrad
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.
Im trying to downgrade my lumia 800 as it is slowly developing glitches and locking up on me randomly.
I tried NaviFirm but it is no longer available.
Im struggling to find a firmware to downgrade back to 7.5 to remove the volume limit and to stop the random lockups.
Can anyone help please?

Hi everyone,
I saw several custom ROMs on Lumia 800 WP Development section. But I'm kinda confused here so I wanna ask, can Lumia 710 ROMs be flashed into Lumia 800? (like Rataplan, Lumiatrix)
Thanks.

Wish me luck on finding phone repair shops that can unlock my L800 DLOAD bootloader tomorrow.

No, the ROM is built for a specific device with inside specific packages. Take a Custom ROM compatible with your Lumia 800.
Nokia Lumia 800 DLOAD to Qualcomm
Guys, I am working on a full tutorial for Lumia 800. From Nokia Lumia 800 Dload to flashing ROMs, it worked on my Lumia 800! I will post it in approximately 4 hours I just needs 10 posts before I can post it with images
DO NOT USE INCOMPATIBLE ROMS!! I bricked my phone because I did, and I can only use it because I were lucky getting it back into the mode where you can flash it.
