Can someone please provide me the firmware for the 2.3.6 ?
If that's what you want to do, go to www.sammobile.com
and make an account. Then, go to www.sammobile.com/firmwares/1
and select the options in the boxes for
MODEL: SGH-T989 - GALAXY S II
COUNTRY: USA TMOBILE.
Next, select the 2012 August T989UVLH1 for Gingerbread.
Like everyone else said, I would recomend that you flash the latest TWRP recovery and then flash the latest Paranoid Android 4.4.4.
