[Fix]-No lockscreen and power menu-Ics Fix - AT&T Samsung Galaxy S II SGH-I777

After hours of trying to fix this issue where my lockscreen wouldnt show up on ics and my power menu wouldnt work and my home button wouldnt work sometimes. Here is a fix
ok so the problem is this-The efs partition is corrupted
1.) You must have the Samsung drivers installed for the i777, available from samsungs website
2.) Once installed, download the attached zip, its a copy of ADB with the needed file inside
3.) Unzip to any location
4.) Boot phone into cwm
5.) Go into Mounts and Storage, and select "mount /efs". Once done connect usb cable to phone and computer
6.) Open command prompt and navigate to the unzipped adb. Issue the following command "adb devices" it should list phone
7.) Now issue the following command "adb push keystr /efs/imei"
8.) Reboot phone and check presence of keystr file in /efs/imei directory with Root Explorer
An alternative for all the noobs-
1.Download Root Explorer
2.Navigate to Efs in the root of youre gs2
3.Create a folder called imei {if not already there}
4.Create a file in the folder imei called "keystr" -Ex. http://db.tt/Pk2U8Nws
5.Hold on the file keystr till you see a menu pop up in root explorer
6.Click on text editor
7.Type "ON"
8.Click save and exit
9.Enjoy and hit thanks
If you're efs partition is totally corrupted then flash this-

Thanks for this, I've had to manually make sure to have a keystr && keystr.bak, both ON, and through root-explorer have had to go to efs/imei to reenable my lock screen.
Such a huge pain

Umm. I downloaded the file and flashed through CWM and yet my keystr file remains empty. No matter what I do to text edit keystr it won't save even if I save it. I feel like I have no options left .

When you are doing it make sure to go to cwm and go to mounts and storage and unmount efs and try all the methods above
