[Q] I want OFFICIAL WP7.5 back!!! - Nokia Lumia 800

I unlocked my Lumia 710 and installed Rainbow mod custom rom. Is there any way to return on OFFICIAL microsoft wp7.5 mango? Please help.

Download NaviFirm Plus, Download the ROM you want
Extract XXXXX_XXXXX_XXXX_XXX_XX_boot.esco from the downloaded firmware in navifirm
The extracted file will be boot.img
Rename to os-new.nb
Flash with downloader_lumia_v20120606.zip

with lumia 800 you can flash new rom from navifirm with ncs or nss
and to return to official wp 7.5 you must firstly get dload bootloader back, and then download from navifirm new rom, after that flash it with ncs or nss
