[HTC Sensation] trkaaa:
i reviewed all your Posts more than once , you first installed ICS firmware 3.12.401.102 , then Custom ICS Rom ARHD 6.0.1 , then RCMix based on 1.05.401.4 ( is it gb , did it Boot ? ) , then Custom ICS Rom RCMix_ICS_v20_STbase ( did it boot normally ? ) , then RUU_Pyramid_Orange_PL_1.45.69.3 ( here you got S-ON ? ) , Whatever you do is at your own risk , also ask malybru for advice

Update : i updated this Method with a successful S-OFF after wrong S-ON implementation guide in my New thread

[ Guide ] Successful S-OFF using htc dev Unlock for GB or ICS after non proper Wrong S-ON with Security Warning (

the Only known working method

) in here

ICS firmware ( Mike link http://xdaforums.com/showpost.php?p=20713530&postcount=1 )

ICS firmware include Hboot v 1.23 ( you have now ICS Rom , but with Hboot v1.18 maybe because of the RUU ) , so your firmware now is not installed correctly ,

ICS firmware include items not existing in previous firmware , So proper Hboot is needed to boot the phone

Check mike instructions first ( htc dev unlocked or locked ) , I guess ( not sure ) to correct this is to flash ICS firmware 3.12.401.102in order to install ICS custom rom

ICS Roms 3.12.401.102 will only boot on certain Hboot versions ( not all of them ) , Hboot 1.17 will not boot ICS Roms 3.12.401.102

RUU flash

from PC , ( try it both htc dev locked or unlocked ) Flash RUU.exe in Fastboot ( not Hboot ) , if not working , then remove Battery and put it back and press volume down and power to go to bootloader , and repeat the RUU.exe flash

after flashing the RUU ( much Better your original RUU, and it boots and stuck on the splash , extract the Boot.img that came with the RUU from RUU zip file , and flash :

use htc dev to Unlock Bootloader

from your PC by Putting boot.img inside adb folder ( same place that includes fastboot ) , then start adb as administrator and type fastboot flash boot boot.img , ( this method proved working )

or try through Hboot (

may not work

) , try without renaming first and if not rename it to PG58IMG or try flashing with original name boot.img , and if successful the device maybe reboot several times before reaching home screen

Custom Rom Flash ( Proved Working )

bootloader should be Unlocked using the htc dev unlock method

Find a Custom rom

Android 2.3.x

( better a

Stock Rooted Rom

with unsecured Boot.img and this is mentioned in the rom features sometimes but not necessarily ) , clean Cache and dalvik ,

Don't use Super wipe

and flash the rom , [ Update ] (try this Rom used by su-27 ) link http://xdaforums.com/showthread.php?t=1201697&highlight=real+stock+experience

the rom boots and stuck on htc splash screen or getting boot loops

extract Boot.img from the rom ( in Multi device Roms , extraxt the boot.img for your exact device ) , then Flash it through

Bootloadershould be Unlock

from your PC by Putting boot.img inside adb folder ( same place that includes fastboot ) , then start adb as administrator and type fastboot flash boot boot.img , ( this method proved working )

or through Bootloader (

may not work

) , without renaming or rename it to PG58IMG.img or try with the name boot.img

the device may reboot several times before reaching the home screen

Revolutionary Method

Should be used after doing one of these 2 methods mentioned above in this post ( Custom Rom Flash or RUU flash ) using Android 2.3.x Rom

the following beneath lines in revolutionary method are discussion specific for Su-27 problem if the above line in

revolutionary method

doesn't work .

ICS firmware disables fastboot commands ( no write ) on 1.18.xxxx-1.20.xxxx

Revolutionary identifies your device as (pyramid-1.18.0000, Android: 4.0.3, ROM version: 3.12.401.2) , so Revolutionary will not be able to write S-off because fastboot write is disabled in ICS with 1.18 hboot

there is an Hboot 1.17 ( which

I think

is Eng Hboot similar or same as 1.17.0008 ) which allows fastboot commands with ICS in this link http://xdaforums.com/showpost.php?p=20681060&postcount=22 . this is the downgrade mentioned by john_matrix and also referred by malybru , download link http://xdaforums.com/attachment.php?attachmentid=829488&d=1324849268 , MD5 75E127836FF2421C3243977FFD625EEF

I don’t know if the above hboot version works with revolutionary or not ( it supports 1.17.0008 )? . ( before Using revolutionary htc dev should be locked and uninstall new htc drivers and htcsync and you

MUST use

old htc drivers v 3.0.0.7)

i don't know any thing about Radio installed by ICS firmware

( is it still there or is it replaces By the RUU ? ,

be very careful with Radio

, google to know will it fit gb and Revolutionary or not ?? )

[ Update ] Successful S-OFF using my above method by member su-27 ( had done a Wrong S-on and Semi Brick Security Warning )

a step by step procedure , the following is what su-27 practically did to implement my method , i added some to his words to make every thing organized and clear

I unlocked device via htc and did factory reset from bootloader. This way I gained access to my 4ext recovery which was not erased during RUU process.

First, I extracted boot.img from custom ROM zip to my PC and put it to the same folder when my fastboot.exe is . Device was in Fastboot USB mode

Next, I put custom gingerbread ROM this 2.3.3 ROM into sd card and flashed it from recovery, then immediately, from recovery, rebooted into fastboot and flashed boot.img from my PC:

fastboot flash boot boot.img

I did it twice, with additional full wipe from recvovery, first with RCMix 3.5 which didn't work with revolutionary, and the second with this 2.3.3 ROM that finally worked and gave me S-Off . Currently I'm on stock, branded Orange PL ROM, relocked, S-on and ready to be sent for repair.
