S5570 lose IMEI after stl5 unlock, help me to restore!
« on: November 08, 2011, 07:24:19 AM »
Hi, after trying to unlock s5570 with stl5 method I lose IMEI.
I've seen that galaxy next (or mini, the same phone) and low cost samsung android device don't have the EFS folder.
Now my imei is 000000000000000.

Someone can help me please? The phone is new...

Thanks everybody!

Well i have a solution to have a default imei instead the one with all 000000000000. Not sure it work or not but give a try.

Try this :
-- Go back to stock rom
1. enter code: *#1546792*#
2. choose (4 Internal) enter code: bj3open
3. choose (2 Test Mode)
4. press left soft key (More)
5. press key 9 ([9] Common)
6. press key 6 ([6] NV Rebuild)
7. press key 1 ([1] NV Rebuild no RF Backup)

8. Reboot phone

and u got an imei that's different than the one with all zeros, but still diferent than the original... however it should allow you to make and receive calls

Let me know if it works :)

is you phone functioning?
if not you may try described below. (on your own risk)....if it still under warranty and if manufacturer cover you, give them back and get replacement.

otherwise do this....

rename stl5.rfs to efs.rfs

Restore (WITH ODIN):
-Open odin
-Add efs.rfs to box EFS and click in START

and see if it can restore board identifier.

let me know if it works :)

Hey , avoid ODIN above post for while. Keep it as last try.

try this way (again no responsibility if something happen :()

remember to take out sim card

Root the phone with Universal Androot
Pull out battery and out it back.
Boot the phone.

Connect with adb shell
-su
# dd if=/dev/block/stl5 of=/sdcard/stl5.rfs
# dd if=/sdcard/stl5.rfs of=/dev/block/stl5
# reboot

Wait for few minutes,
 then pull out battery again and out it back..
after phone boots, IMEI,  should back again.

let me know if this works.

Thanks for your help, just tryed, odin says "Invalid model binary". However i start, and after 2 sec odin crashes and the phone remains stuck in a screen with a pc, a phone and a yellow warning triangle.
Than I enter in download mode, and reflashing the rom the phone returns to work, always with 000000000000000 imei and unknow bt and mac adress...
:( for galaxy s there are guides online, talking about nv_data.bin in /efs folder, but in s5570 there isn't the /efs folder...

Help!!!!!!  :'(

It is impossible to recover your phone if you play with EFS :(
Just go to Samsung Service Center

at very last option he wanted to brick phone completely otherwise samsung wont replace or repair it. IMEI reset generally not cover in warranty, i guess they know we have messed up with rom. ;)
