Please make Factory Reset and repeat "Repair IMEI" operation (write service IMEI from the Software list, not any IMEI).
Note: it is important to restart the phone via its menu as operation ends (don't disconnect the battery!).

Also look here: http://forum.gsmhosting.com/vbb/f684...olved-1952431/

Still need help and please sir!

If I download lower version like 4.3, will this problem be over?

[Octopus box]

Please fully charge phone's battery and try to perform steps 1-5 with different firmwares.
If problem will remain the same - this can be HW problem (problem with phone's flash chip).

Hello sir, thanks so far!

But the problem is not from battery neither is hardware, The phone was working fine before I downgrade it just to be able to change the imei and now is always saying "not registered on network" and the imei could not be repaired back.

To show that is not battery I flashed it with odin and md5 file and it can flash complete but with the file you told me to use, it stops on the way.

Please can you give me the md5 file link of the version you told me to use (expectially if is on sammobile site). Let me try it too, may be with the file it would be ok but something is preventing it from completing flashing with the great octolus.

I love this box and I always stand for it 100%.


Below is my flashing logs for odin and octoplus showing it not battery folt.
