Thumbs up finally worked out! GT- I9305

Many thanks to OP! YOU SAVED MY BACON!!!!

Samsung Galaxy S III LTE - I-9305

Method 2 - created keystr at efs/imei/

and then

echo -n ON>/efs/imei/keystr
echo -n ON >> /efs/FactoryApp/factorymode

I had a screen that woudn't go away, annoying one ate desktop of mobile.

Also lost IMEI and fixed with a flash Param_Bin, see quote: "Recovering IMEI And Data Connection After Flashing WRONG Root Package Intended For I9300:" at:

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.
