After lots of searching, I need a newer su 3.0.7 for 2.3.6. Essentially this has a more recent root guide http://androidforums.com/galaxy-s2-t-mobile-all-things-root/627099-guide-root-rom-sgh-t989.html
excellent, it worked. I'm on 220.127.116.11.2_user_323001720 too.
1. (cant say this enough) ROOT THE **** PHONE
2. Install a custom official rom
3. Enable data2ext
4. enable apps2sd
4. Install Flash player 10.- (whatever is the newest version)
5. download CPU tuner from the android market
Wifi seems to have very poor signal reception. My wifi is in basement below me and I get 0 bars. My laptop gets five bars. Any ideas?
