NOTE:
DO NOT ask for a backup. If you do not have one, you have to accept to be permanently on Android like me.
Create a folder somewhere that we can use
Copy the backup to that folder
extract the zip I attached to this folder
Download these into the folder:
imgman.exe
Original partition table
recovery_unsecure.img
EDIT: Someone seems to have taken down the main Android4Lumia thread, along with it's creator and it's attached files. The files can be found in the attachments down below.
create another folder inside this one called "parts"
run this command:
Code:
replace <backup.img> with the filename of your backup
Code:
ADB should disconnect at this point
Code:
WHERE <partition> is one of these (flash them in this order):
TZ
SSD
RPM
WINSECAPP
MODEM_FSG
MODEM_FS1
MODEM_FS2
UEFI_BS_NV
UEFI_NV
UEFI_RT_NV
UEFI_RT_NV_RPMB
PLAT
MMOS
EFIESP
UEFI
Then reboot the phone with
Code:
Phone will show smiley of death, that's normal
From this point, you can use WDRT to flash a clean WP, or reflash the one from the backup using thor2
thor2 should be at
64-Bit Windows
32-Bit Windows
To do this
Code:
wait for the phone to show the alternative NOKIA logo, where the text is not centered vertically
Code:
EDIT: or just flash your phone's FFU file (download from lumiafirmware.com ):
thanks to @feherneoh for this hint
And then reboot:
WP8 should boot 
Instead of thor2 you can flash MainOS and Data partition/FFU (with both partitions included) with WPInternals or WDRT
