O2 dell streak downgrade rom

[Guest Urbansilverstar]

I foolishly updated my o2 dell streak to 2.2 from 1.6 to find my rebel sim now no longer works, does anyone have a definitive guide on how to downgrade to 1.6 or even 2.1 from 2.2 I've tried a few guides but none seemed to work so far, I just end up booting to blank screen.

If it's an O2 2.2 then all you should need is an earlier O2 rom and just run it from a file manager.

That has worked for me.

Have fixed it, you need to download the 8105 recovery image and place into C: root

Download 8105 firmware.

Put firmware onto a memory card and rename Update

Put phone into fast boot by restarting and holding camera button

Connect to a pc, and wait for phone to connect (may need to install drivers)

Run dos command and go into root (C:) type fastboot recovery 8105.img or whatever you have called it.

Type fastboot reboot

Disconnect cable and wait for phone to reset

On dell logo hold volume keys

Scroll to update and press camera button

Wait with patience
