Hi..just wanted some help with clarification on a few things. I upgraded the firmware to the one needed to install the ICS ROMs, but have reverted back to my original stock ROM using a NAND restore.

However, I noticed the radio and the HBOOT is still with the newer firmware one. So does NAND restore not restore them to the original? (the NAND was done before upgraded to the newer firmware).

Also, if I want to go back to the previous radio that was already on the phone. How can I do that? Do I use the RUU file? Will that restore everything back? And will I lose root?

Thanks for your help.

Why do you want previous FW, if current one most likely work perfectly?

Nandroid only restores/backsup /system, /cache, /data, /boot (kernel), and /recovery. It doesn't touch radio, boot, or any other firmware stuff.

I am not sure if it's the problem with it, but it seems the battery is draining very fast after I upgraded to this new firmware for the ICS and not back on gingerbread. That's why I want to restore a previous radio etc..

Actually, I mainly want the firmware that was released for the lastest gingerbread (i.e. t-mobile update in Dec). I had flashed the firmware before...after that flashed the other one for the ICS. Can I just reflashed the previous version of it?

Does RUU restore the radio back? and does it keep root?

RUU restores everything back, and i mean everything. And root, it'll be gone, but easy to gain again. You might need to superCID to be able to downgrade hboot (to flash earlier version which is in the latest t-mobile ruu)

Oh I see..so RUU files brings restores back to original.

I have super CID and everything root etc.. how about just flashing the PMG file that was for the update back in Dec for TMOUS? I just want to see getting rid of this new radio will make a difference.
