SEEMS TO WORK ONLY WITH VERSIONS THAT GOT THEIR UPDATE BEFORE NOVEMBER (EUROPE SHOULD WORK, ASIA/INDIA I DO NOT KNOW!!!)

IF THERE IS A NEW TEMPROOT EXPLOIT AVAILABLE IT SHOULD WORK FOR NEWER VERSIONS ALSO

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://forum.xda-developers.com/showthread.php?t=1272595)

- windows os on your pc

- RUU http://forum.xda-developers.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!!

What's the difference between using the misc_version here to "change" your version compared to getting your phones misc version .img from "dd if=/dev/block/mmcblk0p17 of=/mnt/sdcard/mmcblk0p17.img" and then altering it and re uploading it?

To my understanding the one uploaded just patches your misc version where the other one you do it manually.

Or am I so lost I should go home?
