Possible downgrade - bootloader change?!

[Tengaku]

Hewwo everyone...

I fell more early on an niteresting forom post...
On this post, we can find a program from ATF...

This tool seems to be able to downgrade a Lumia 800... (and maybe more)
Thus, if someone skilledenough want to look into it, here is the link of the post

And here the link to DL the program : http://is.gd/y47JNr

I hope this may help to downgrade the Lumia 800 and be able to change DLOAD by Qualcomm by flashing an old firmware...


P.S. : If you're having issues with ftd2xx.dll, copy it from :
C:\AdvanceBox Turbo Flasher\Driver\ATF_NEW_DRIVERS\i386
And paste it to : C:\Windows\System32

There is no "magic" firmware with a Qualcomm bootloader.

There is no "magic" firmware with a Qualcomm bootloader.

They existed... right?!
If we can do a downgrade... a backup... a custom firmware... etc...
Maybe it's possible to get a backup from another phone with a
qualcom bootloader, and flash it as downgrade...

It's just an idea... Idk if it can really be done... but still something
to scratch here...

Backups are device-dependant. This means that the backup can only be restored to the device that made the backup.
