[HTC Sensation] trkaaa:
Salam mokalov , i am confused about what you did ?

what i understood is that you did S-OFF using JumpBear S-OFF method , then changed your cid to super cid , then installed GB RUU.exe , then done S-ON again ? so you are now on GB original rom and S-ON , is that correct ?

to know if you are S-ON or S-OFF , go to bootloader screen and it is written there

to answer your questions :

charging problem is usually because of old CWM recovery v4 ( it doesn't charge while the phone is powered off ) , CWM v5 doesn't have that problem , also ICS doesn't display Battery percentage correctly ( htc bug )

shipped rom thread is here and include ICS RUU's http://www.filefactory.com/f/c87a2330449af512/

you can upgrade to ICS with S-ON and HBOOT 1.18 , but it is not recommended because if htc in a future updated put something into the update to stop JumpBear S-OFF method from working , you will be stuck

maybe the OTA update is not available yet for your Region/or carrier ,

to receive OTA update your phone should have the following :

you can receive OTA update if you are S-ON or S-OFF

, so S-ON is not mandatory

official Stock Rom " stock recovery is included in the RUU

stock recovery " for S-OFF devices they need to flash at least the Stock recovery instead of the custom recovery " , or for S-OFF devices Just flash official Stock Rom

Basically you will need to put your original cid instead of super cid , but you can try first with super cid

Recommendation is :

don't stay S-ON , Do S-OFF while you are on hboot 1.18 as follows :

first use Revolutionary directly , done

if Revolutionary at the end gave you this error " Zerg ...... can't root or S-OFF " then your software version is too high , you will need to use tacoroot with revolutionary to S-OFF , here http://xdaforums.com/showthread.php?t=1541087&highlight=forevernoob , also you can use this tool to simplify the process [TOOL] HTC Sensation/XE/4G Super Utility (all in one) by kgs1992 , or http://xdaforums.com/showthread.php?t=1661631

tacoroot will put your device in a bootloop with root access , during that bootloop you start Revolutionary and do the S-OFF "

Start with a fully chargd Battery

" , the whole process inly takes very few minutes , don't let battery die during the process

follow this title Revolutionary Method and Precautions ( Gingerbread ) here Guide To Successful S-Off After Wrong S-On Brick (ICS/GB) , to avoid errors while using revolutionary

for installing software do either of the following

if you want to Stay on Official Stock firmware , install an RUU ( GB or ICS ) and you will be able to receive OTA as normal " you may need to put your original cid Back "

or you can install Stock Rooted Roms " they are almost stock except removing stock recovery and stock hboot " , this method will not receive OTA , but for every new RUU " OTA " you will find a developer who rooted it and you can install the new version , go here Latest Stock ICS Rom ( this requires to install the proper firmware first , then the Rom then Rooting tools ) , to install firmware go here User Friendly Firmware Upgrade

or you can install ICS custom Rom ARHD 6.6.7 , it is the nearest to stock software and always based on the latest OTA

with ICS Custom Roms , you should install 4EXT Recovery " the best recovery now " go here Guide for installing Both Custom / Stock Recovery ( Downloads and Methods )

for how to install Custom Roms and my easy method to do so after S-OFF go here Post # 2 , go to title 2) Easy Method for Installing ICS Custom Roms ( S-OFF Devices )

i hope i answered all your questions
