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+.

Hi,
i still wait like many of us for a solution to downgrade from DLOAD to Qualcomm Bootloader on the Nokia Lumia 800.
The 710 has a solution via NSS.
Also other Threads show how to do it with MobileEx and AdvanceBox Turbo Flasher .
The Newest Versions of them are listed here.
NSS : http://www.genieprojects.co.uk/files/NssPro_0.53_0_b.zip
MobileEx v3.5 r2.4 : http://forum.gsmhosting.com/vbb/f550/mxbox-v3-5-revision-2-4-public-discussion-thread-1558419/
AdvanceBox Turbo Flasher : http://forum.gsmhosting.com/vbb/f609/
The Problem is that ATF and MobileEx need the hardware devices, which are damn expensive and needs to connect with the PC to use the Software. Or use JTAG with special cables, no standart user has experience. There are several emulated (Cracked) versions of the old versions of these Software, but i dont want to link them as its not allowed.
NSS has a new version, and there is still no OSBL version of Nokia Lumia 800 firmware.
Don't we have Dumped Firmware of Nokia Lumia 800 OSBL (Qualcomm) to flash easylie with NSS like with Lumia 710 ?
Is there Any Development to get that Qualcomm to Lumia 800 ? Did anyone Reverse Engineer how 710 works and "ported" this method to 800 ?
Did anyone found or dumped the OSBL (Qualcomm) Firmware for Lumia 800 ?

bootloader on 800 is still not downgradeable
i would love to see a (software-)solution for this as i have also a lumia 800 with a dload.
710 has a software solution with NSS
but i know someone has the OSBL firmware for 800 too or could get it to let it work on NSS with 800 too

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.
