If you upgraded your device with official RUU_VIVO_ICS_35_S_HTC_WWE_4.10.405.1_Radio_20.74.3 0.0833U_3831.18.00.11_M_release_266013_signed

and your at HBOOT 2.02.0002 with S-ON then dont worry.

Follow below steps and you are back to normal to BLACKROSE with your own choice of ROM.

First Remove all kind of HTC drivers/HTC SYNC software from your computer and install these drivers (click to download) HTCDriver3.0.0.007.exe
Download attached files and link provided in my post.

1. Get the UNLOCK.bin file by registering htcdev.com and ( I hope you know how to unlock through HTCDEV.com) (attached adb.rar contains adb.exe , fastboot.exe and misc_version file)

2. Now In the bootloader You will see ***UNLOCKED**** at this time flash the recovery ( i love 4xt) So i downloaded 4xt and use this command.
( you need to be in FASTBOOT-USB MODE)

Quote:

fastboot flash recovery recovery.img

(where recovery.img is could be any recovery either clockmod or 4xt)

3. Download the Superuser-3.1.3-arm-signed.zip put it on SDCARD

4. Boot in to recovery and install Superuser-3.1.3-arm-signed and reboot (here you got root access to the device)

5.Do a normal boot enable usb debug and connect to the computer .And in the command prompt run these commands to check you got root access or not
Quote:

adb.exe shell
You get a prompt like this $ means you are connected to the device then type su and press enter if your prompt change to this # means you got root access and then exit

So until now we have root access to our offical RUU ICS ROM and Now we are going to downgrade it .

6.Now type these commands in the command prompt
Quote:

adb push misc_version /data/local/tmp/ <---- copying our file to the device

adb shell <--- you will get $ prompt

su <------you will get root access

chmod 777 /data/local/tmp/misc_version <--changing permissions of the file to execute

/data/local/tmp/misc_version -s 1.00.000.0 <----- you are faking your device for the official RUU installer that it need upgrade to gingerbread

reboot bootloader <-- rebooting to bootloader

Now your device will reboot in fastboot-usb mode (as it should be remain attached with computer) .Do not worry as it will still show same HBOOT 2.02.0002

7. Now run the RUU_Vivo_Gingerbread_S_HTC_WWE_2.30.405.1_Radio_20 .2808.30.085AU_3805.06.03.03_M_release_199308_sign ed.exe

8.After complete installation you will have HBOOT 1.13

9. Now follow Section 2 of this thread http://forum.xda-developers.com/show....php?t=1705913

After getting S-OFF you can install BLACKROSE HBOOT 2.02.0002 OR any other HBOOT of your device and your choice of ROM.

Feel free to ask if you feel any problem I tried my best to explain it with my poor English

Its RUU ICS 3.5 .I upgraded from BLACKROSE and now want to downgrade or S-OFF.

P.S. Its unlocked and rooted .


Please HELP.

This is not a Development topic and should have been posted in the General Section.

You need to go to the General Section and check out the Downgrade Script sticky post. It may work with HBOOT 2.02.0002 if the tacoroot exploit still works.

Bro i have done it...

As i have already told you that I was on official RUU ICS Sense 3.5 with HBOOT 2.02.0002

Also i unlocked it through HTCDEV
and loaded 4xt Recovery as well.

Now Phone was loaded as normal i attached with computer in charging mode.
and use these code from the IncS_MVDTKv3.2

C:\Downloads\d\IncS_MVDTKv3.2\IncS_MVDTKv3.2\files >adb push misc_version /data/l
ocal/tmp/
* daemon not running. starting it now *
* daemon started successfully *
2553 KB/s (367096 bytes in 0.140s)

THEN
Quote:

adb shell

su <------- (THE KEY POINT IN THE WHOLE SOLUTION )



chmod 777 /data/local/tmp/misc_version
/data/local/tmp/misc_version -s 2.00.000.0

Then This is the output

Quote:

/data/local/tmp/misc_version -s 2.00.000.0
--set_version set. VERSION will be changed to: 2.00.000.0

Then i reboot to bootloader

And RUN RUU_VIVO_SENSE30_S_HTC_WWE_3.11.405.2_Radio_20.480 5.30.0822U_3822.01.08.14_M_release_252414_signed.e xe


So currently i am on HBOOT 2.01.0001. I could downgrade more below it if set it to 1.00.000.0 in the misc_version.

NOw could you please send me the files to downgrade HBOOT 2.01.0001 so that i can install blackrose ,you mentioned them here http://forum.xda-developers.com/show...373697&page=87

Thanks,

Thanks,

The RUU/ROM you are running is too new. You need to run a RUU/ROM that has HBOOT 1.13. That is the key to the downgrade!!!! Once you are on HBOOT 1.13, then you can run Revolutionary and get S-OFF.
