If you’re a fan of The Unlockr and happen to pick up the AT&T Galaxy S2 (SGH-i777)… You may have flipped upside down and started dragging your head on the keyboard in frustration after you realized your wifi is completely broken! I have the solution.
Fluff: After digging around the XDA and Android Device Forums I found that factory AT&T Galaxy S2 typically came with 2.3.4, most write-ups online is for 2.3.4. Samsung’s recent OTW release 2.3.6, left thousands of Superusers with wifi connectivity issues due to having the wrong kernel.
How To Fix AT&T Galaxy S2 Wifi Issue Under 2.3.6
1.) Calm the fuck down, sip your coffee, breath.
2.) Goto: http://forum.xda-developers.com/showthread.php?t=1289460
3.) Download the latest Attached File (as of 2/12/2012 it is DD_02072012.zip note the retarded naming convention is a time stamp for DD_[02/07/2012].zip – I thought the top attached file was the latest)
4.) Connect Galaxy S2 to your PC/Mac, enter USB Storage Mode, place the .zip file onto your device (just put it in the root).
5.) Power off device and enter ClockworkMod Recovery Mode (By holding down the volume down, volume up button, and the power button. Let go of the power button once the device turns on and continue to hold the volume buttons until the recovery screen loads.)
6.) Use vol up / down to highlight “install zip from sd” then use the home button to select (maybe different on other devices)
7.) Select the .zip file, install, reboot device.
When the OS loads you should be able to go to Settings -> Wifi and see all your hotspots. Connect and test.
Note: Please let me know if this does not work for you in the comments. I can further assist / update for others. Thanks!
UPDATE AS OF 6/26/2012: As of June 26, 2012 Samsung has released the OEM Ice Cream Sandwich. Previously, I decided to try out the leaked version that surfaced on the XDA forums. I am currently working on trying out the Samsung official release of ICS. I advise precaution, PROCEED AT YOUR OWN RISK.
UPDATE AS OF 12/1/2013: My AT&T Samsung Galaxy S2 has died as of 11/29/2013… The power button seems to have failed, causing to randomly turn on and off or stick (making it so I cannot wake / lock the screen.) I am very distraught! 🙁 If you by chance found this post, I hope this works for your phone. If you run into issues I can do my best to help. But if you run into an issue and figure out a way around it feel free to leave feedback for future reference. Ironically, I was able to pick up a free Samsung Galaxy S4 on Black Friday. Time to void the warranty! RIP S2, if I find another one on CL cheap I’ll turn it into a dedicated car mp3 player. 🙂
