Hi.

I have a BIG problem in my hands, ok but i smile anyway :).

O spent a lot of days looking for a solution to fix my Null IMEI but no chance.
The phone is a CLONE Samsung S5 SM-G900H with real MT6572 (MT6589 is fake), we can see on image the MTK Droid tools diagnost.



Well, i flash one Rom before a backup de NVRAM and i lost the "/efs" directory so, i don't have the ".nv_data.bak e .nv_data.bak.md5" files.

Anyone can say me where can i find the solution? I tried almost everything, the IMEI can't be written always.
I guess i need the original Ubifis ROM for this phone, to restore "/efs" directory or the NVRAM/IMEI backup for this one.
I tried flash some Roms but no one works because of blocks, partitions or something.
Some correct ROM to flash with SP Flash, already rooted with CWM Recovery and /efs is the perfection :).

Thank you in advance!
