Hi guys,
I CAN confirm this method works!
If your branded you need your carriers ruu
If your unbranded you need a europe or wwe ruu (I think)

okay now more in detail

first you have to know that you will loose all data on your system, please backup bevor doing anything!!

what you will need:

- misc_version http://www.thinkthinkdo.com/trac/project1/wiki/misc_version

this will change your version information on your desire s later

- zergRush https://github.com/revolutionary/zergRush/downloads

this will give you temporary root privilieges (so that you can change the version number)

- phone

- chargecable

- adb-shell (see this guide http://xdaforums.com/showthread.php?t=1272595)

- windows os on your pc

- RUU http://xdaforums.com/showthread.php?t=1002506
--> please notice: if you have a branded device, use a branded RUU to downgrade!!

1. Connect your phone to your PC in debug mode (Set option in settings (application --> developer)

2. unzip the downloaded files in a folder (e.g. c:/Users/yourName/Downloads)

3. run the Terminal (Windowsbutton + R --> cmd) and change into the folder where the files are (change folder with 'cd')

4. now type to the terminal (every line is one command!)

adb push zergRush /data/local/tmp
adb push misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/zergRush
adb shell chmod 777 /data/local/tmp/misc_version

now type
adb shell
cd /data/local/tmp/
./zergRush

--> now adb shell closes and restarts, instead of having a $ you have a # which means root

5. now type

adb shell /data/local/tmp/misc_version -s 1.27.405.6

--> this will change your version information

6. now you can doubleclick on the privous downloaded RUU and follow the steps. it may tell you from going down from version 2.xx to 1.xx but it is possible.

7. phone reboots and when it is up again you should have android 2.3.3 hboot 0.98.0000 S-ON

8. now just download revolutionary from http://revolutionary.io and create a beta key and start programm

if it was helpful, please use the thanks button!!

How do I know if my phone is branded?
thanks for help.

If you have the logo of any mobile operator when booting the phone (T-Mobile, Vodafone, etc.)

The other way to check is to look in Settings -> About Phone -> Software Information -> Software Number. The third group of numbers stands for the version.

Example 1.28.401.1, 1.47.401.4, 2.10.401.4, 2.10.401.5, 2.10.401.8

401 - clean European unbranded version
720 - version for India
707 - Asian version
111 - T-Mobile version
206 - O2 UK version
etc....

for a certain brand or version just see the list of RUU here (it is the same as posted by the OP) and look on the third group of numbers in the RUU version

Btw version 405 (suggested by the guide here) stands for WWE (World Wide Edition or World Wide English) which is multiregion, thats why it does the trick. But you can change your misc version to the same (or older not higher) as the RUU and it will flash flawlessly

1. why did you change the permissons two times? try again with chmod 777
2. maybe give it a second try.

which version do you have? branded oder without?

@gefilus: theoretically no because there is no "big" engagement into the device. but i wont be responsible!!

While running the RUU after following the instructions, I get error 155 (unknown error).

I have attempted this in fastboot also, with the same results. Any help?
