Method 2 - created keystr at efs/imei/

and then

Default Help with galaxy reverb.

Hi, I have a galaxy reverb, M950 that I bought with missing MEID/ESN.
I am having this same problem.

Can someone help me fix it?
I don't want to use it for calling or anything. Just using it as a multimedia device.
But I want the lockscreen to work.
It is working if I install the ICS rom but not on this JB rom.

Can someone help in any way?
Since I don't have a backup of EFS I cannot restore . Is there any other way I can fix the EFS?
I have tried this method of "keystr" file. But it doesn't work(most likely because itsnot galaxy S2).

Or can someone tell me how to compare which file(s) is responsible for the working lockscreen in ICS rom so that I can do it in JB rom?

This isn't the I9100's section so heck if we know. Try the s2's threads.

Default Here is what worked for me...

Before you do any of this, please note that this was caused by the note radio, aka uclc5, and if u still have it, please remove it! Also causes include a corrupt efs partition. This guide will help to restore key files important to the operation of your phone

There are three methods available. The first and second one are recommended. If you are uncomfortable with adb and command prompt please use method one

UPDATE: This has been confirmed as working on T989!


WARNING!
Method 3 is only to be used if one and two fail, or if you are positive your efs is corrupt!

Original source for solution, with a few method changes by me:
http://forum.xda-developers.com/show....php?t=1438451


METHOD ONE

1.) Use busy box installer from the market and re-install even if u have it working

2.) If step one doesn't work, install super su updater, and update it, then try step one again.

3.) Boot into cwm and dark side wipe 3x

4.) Flash rooted 2.3.5 from thread below

5.) Boot into rom and install root explorer

6). Navigate to /efs/imei/

7.) Press menu and select new file

8.) Name it "keystr" exactly as in quotes

9.) Long press keystr and select edit in text editor

10.) Type "ON" and press back, selecting save.

11.) Reboot and make sure keystr file is still present.

12.) Now u have a few options. U can flash ics back using either Odin one click (UCLA4 or UCLD2), but I don't recommend this. Flash one of the ics roms from the development section, we have great devs!

Rooted 2.3.5 zip:

METHOD TWO

1.) You must have the Samsung drivers installed for the skyrocket, available from here:
http://downloadcenter.samsung.com/co..._v1.5.14.0.exe

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


METHOD 3
Flash attached EFSFix.zip in cwm and reboot.




A SPECIAL THANKS AND SHOUT OUT TO:
