ReplyDeleteMy story
I downgraded from lollipop (nameless rom) to kitkat custom rom and the efs null error appeared. After lot of trials, came across your page which was a mobile saver
worked on mine
ReplyDeleteworked on mine 4.3 s3
ReplyDeleteMr Wolf I've got the same problem.
ReplyDeleteHow i got my IMEI null/null & Baseband unknown,
I've had flashed the Pheonix Rom for my S4 I9505 & it was smooth and working like a charm and after 2, 3 months my phone reboots itself and i've got no service and my IMEI null. :S
"And then again Sometimes my phone used to reboots itself and i've got my IMEI back again."
And that goes again n again.
and then i've flashed my device on Stock Firmware 4.4.2 and STILL THE SAME.
Please Reply ASAP.
STILL THE SAME. you mean rebooting or IMIE?
ReplyDeleteAfter flashing stock FW did you factory reset, Flash the latest FW for your device cause restarting problem sometimes happened cause of some updates.
Rebooting.
ReplyDeleteYes i did Factory reset plus wipe cache partition.
But this didn't fix my problem either.
My device reboots usually and my network signals come and go. (IMEI null/null to 1/01)
Flash the latest FW file for your device model
ReplyDeleteIf it doesn't fix it try this http://forum.xda-developers.com/galaxy-s4/general/fix-reboot-crash-problem-ng6-root-t2921584
Well, thank you so much.
ReplyDeleteAs far as i know flashing the latest FW won't fix thi IMEI issue.
But let see as i'm about to flash UK BTU 4.4.2 I9505XXUGNG8.

ReplyDeletehi!!! can you help me please?? how did you do it? any efs backup?? some root?? or step by step as described here?
ReplyDeleteW0lfDroid
My phone's imei was gone after rooting it.... i tried alot of other guides but this seemed to be the only one that did the trick.
ReplyDeleteI have simply followed all these steps as discribed above and flashed the ND1 file to my note 2... when odin said complete, my issue was fixed
btw: when using odin with the note 2, turn off auto reboot, else the phone will reboot already while it is still flashing... just reboot it manually when it says PASS (only pass, no RESET or annything else)
good luck
Flash the latest modem for I9300
