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.

THANK YOU SO MUCH!!

im having trouble with this and i do not understand, but my wifi is not working on my device…galaxy s2 on att
What exactly are you stuck on ethan? Also note; currently you want to grab DD_03072012.zip
My wifi was working fine since ATT galaxy S2 release, in the last month however the wifi has stopped working. It says connected but it won’t load anything in any app or play store. Also I’ve started to notice some mobile data issues slowly disabling the 4G connectivity. I have no clue why this is happening and I’m running 2.3.6 OS. I’m a computer guy and yet everything I’ve attempted on my router or on the phone has not improved the issue!
Thank you sooooooooooooooooooooooooooooooooo much…….
GRAAAAACIAAAASSSSSS!!!!!! THANK U SOOO FUNKING MUCH!!!!
Doesn’t work
. I get an error that says E:signature verification failed when I try to install the DD_03072012.zip
Are you running the AT&T Galaxy S2? Did you do the root proceedure from The Unlockr? I know there are a few different write-ups, this article is specific for the Unlockr as they provide a link to the specific ROM / Bootloader I’ve placed on my SGH-i777
THANK YOU SO MUCH! I was at my wits end and stumbled upon your site. The fact that you took the time to hear about a problem then root around to find the solution and then share it, with those of us who dont know how to do this, is just so so well you know. most appreciated . tnx_6… and the coffee is always good
THANK U SO MUCH YOU ARE A PRO
Thank you so much! its worked !
Hi, will this work on GT-I9100?
i tried it. it didnt work on GT-I9100. the back and home keys were disabled. but thanks
did you fix the disabled button and key? got the same problem here but no idea how to fiy it ;(
I’m not sure what issue your are talking about.
This is AWSOME!!! Thank you so much!! It totally worked!! Your God to me!!! =)
What if you don’t have CWM installed? Not sure why, but for some reason the ODIN i used to root did not install CWM. In recovery mode, it doesnt find any zip.
I should have clarified that part, on The Unlockr, the writeup on how to root the part “Flash a Custom Recovery onto the Device” places CWM onto it.
God damn Unlockr has been infested with shit ads.
Bro…as of today, 03 Feb 2013 this worked like a charm! Your hard work and dedication to helping people out is appreciated more than you know.
No problem! Thanks for leaving a comment. Just a heads up, I am now on Jelly Bean (Cyanogenmod 10) – I used the app ROM Manager to get the nightly builds.

Yeah, DD_03072012.zip
