[Q] t-mobile sensation 4g - ics upgrade puts me in big trouble!

---

complete noob! please help!

I received the OTA and upgraded the phone to ics. The phone is an unlocked(to accept any sim cards world wide) t-mobile sensation 4g. When I upgraded the phone, it had a Qatar telecom SIM card inside and it rebooted and connected to the mobile network. However, it doesnt want to do wifi connection! it doesn't list any wifi SSIDs to connect!!!!!

to test, i put my t-mobile usa sim card and the wifi works fine!!!! also, vodafone UK sim card works fine!! But, when I put Qatar telecom sim cards, the wifi doesnt want to work!!!! i tried my friend's qatar telecom SIM card to see if the problem is with my sim card, but that one too didn't allow me to connect to wifi. I tried without any SIM cards also and then too it didn't list any wifi access points!!!

I did factory resets 2 times already and that didn't help either.

i rebooted the phone and pressed the volume button down and the phone shows the following....

Sent from my FireStorm StockMod (Release Date 5.18.2012) Sensation 4G

i am downloading the RUU now!

will it put what they call "stock recovery" also?

but what I don't understand is when i put a different sim card, the wifi works! i can see full signal strength and connected to my SSID. is it any way connected to SIM card?

i will run the RUU and then let you know.

ran RUU linked by steve. unfortunately it comes with a 155 error. then I get update fail, security fail

i so much like the ics, but the wifi issue kills me!

may I know how I can put the phone exactly to how it came out of the box?

the software and stock recovery?

t-mobile site doesn't give any information on the problems....
