How to RUU another official rom without touching AlphaRevX's S-off

---

Sry for my poor English. This is for ppl who flash RUU-AU-OPTUS rom mainly to get S-OFF, then wanna flash back the rom they were using before they patching the AlphaRevX.

Here are the simple steps:

1, get the rom.zip from another RUU*.exe, i mean the one you want.

2, unzip the rom.zip into many img files

3, delete the hbootXXXX file. and if you want keep clockworkmod, delete recovery file as well.

4, use 7-zip to add all those files into a new .zip file (no winrar, 7-zip only)

5, rename the new .zip into the PG32IMG.zip , copy into sdcard, reboot into hboot and flash.

6, remember do a factory reset, cuz the AU_OPTUS rom will leave some funny area settings and data in the phone.

edit: sry i missed, goldcard is a must!!! make your sdcard a gold card b4 doing all these. thx 007!

Hi, tried this method just now but nothing happened.
Tried flashing it like you described as PG32IMG.zip it looks like it is running the flash but no change after reboot.
Tried also with recovery (install from zip) but unfortunately doesn't work also.
Am i forgetting something in the process?

Your missing goldcard...

This is also explained in the downgrade guide in this forum

Always something missing . Thanks.

didnt you just forgot to make changes to some specific text file as well?
