I'm not taking credit for any files or programs here I just simply constructed a full guide on how to downgrade etc. for noobs and also people that is struggeling like I did .
Please be warned that you might damage your phone and also that your waranty voids after you unlocked your bootloader so I don't take any responsibility !!!!! But be assured if you follow my instructions you'll just be fine !!!!!!!!!!!!!!!!!!!!!!!!!!!
It took me 5 weeeeeeeekssss to find all of these and figure everything out so be greatfull !!!!
I'm going to tell you excacly how i did it !
First things first ....
Copy Cyanogen mod 7 android 2.3.3.zip to your sd card
Open "HTC DESIRE S - All in one toolkit" and run it.Remember you should be in bootloader for this ( volume down + power ) and the navigate with arrow keys to fastboot and select it using power button. Follow all the instructions in the lefthand corner on how to unlock your bootloader
Next you have to flash custom recovery . Look in the right hand corner and select TWRP 188.8.131.52 and let it flash.Sometimes it will say your phone is not detected just exit that command promt and the next command window will flash it.
Now you have to go to your recovery ... While in fastboot select bootloader and then recovery ... A htc logo will appear and about 10 sec from that an TWRP logo .
After all that is done go to install select zip and find the cyanogen mod 7... .zip you pasted earlier on your sd card and then flash it . wait untill it completes.
Now you have to reboot your phone look for reboot in the TWRP menu and select reboot then bootloader . Once your in bootloader again go to the folder where all my tools are located that I provided for you .
Go to android tools and press shift then right click and select open command window here .
copy and paste the following :
fastboot flash boot boot.img
After its completed select the reboot option using your arrow keys.
Wait until cyanogen mod 7 fully boots up
Now go to settings > applications > developer options and enable usb debugging
After that go to android tools folder again and open the command window again paste the following :
adb push C:\downsaga\misc_version /data/local/tmp
adb shell chmod 777 /data/local/tmp/misc_version
./misc_version -s 1.27.405.6
After that the phone will be in bootloader again already in fastboot and then just type :
Fastboot oem lock
After that the phone will be in bootloader again already in fastboot
Now open the ruu I have provided for you and run it until it completes and whalah !!! You have hboot 0.98.0002
Now if you want to root it use the superoneclick app I provided and after that s-off also your bootloader with revolutionary i provided just follow the clear instructions(Your phone must be turned on and not in bootloader ! also remember to turn on usb debugging again !!!! )
after all of thos when you reboot into bootloader things will look like :
SAGA PVT SHIP S-OFF RL
(current date),(current time)
