Known Problems
If you have problems while re-rooting or custom recovery (unrevoke) try to downgrade again with the above procedure.
Make sure you have made a new goldcard.
If you have problems e.g. 140 ERROR please follow these instructions (thx to raz2133)
This will fix your MISC Partition so you can flash back original RUU files.

The User maximini1 has found a thread where they describe how you can downgrade to 0.80 again.

So i try to explain how you have to do it.

Preparation
1. Make a NEW Goldcard (here)
2. Download PB99IMG.zip (here - MIRROR - germany MIRROR2)
3. Rename the downloaded file to "PB99IMG.zip" and copy it onto your SD Card.

Flashing
1. Shutdown yor mobile
2. Hold Volume up and press power
3. wait until PB99IMG.zip was found and checked
4. Press Volume Up <yes> - PICTURE 1
5. Wait until all steps are done. DON't POWER OFF YOUR DEVICE!!! - PICTURE 2
6. After flashing press Volume Up to reboot
7. done

Happy re-rooting

Looks like it's possible for those with an unbranded/unlocked phone:

1. download the file to SD card.
2. rename to PB99IMG.zip
3. boot into recovery (turn phone on while holding down volume)
4. just let it load the zip file and press yes when asked to install

Easy as that!
