Z3X makes Autobackup mate, search it in Z3X directory, you can use any compatible CERT, post log.

thats maybe right when the device still have baseband, but i got unknown baseband
I mean that autobackups are useless, it doesnt have efs backup its only nvm backup.
thanks, and i still need a g900t efs backup

Have you TRIED to load the backup? AFAIK, it has everything you need for a corrupted baseband. If it's still corrupted afterwards you're going to need to wipe the EFS again (manual way through ADB). Either that or your modem partition is damaged or your hardware is damaged.

how to load the backup?
there is no such thing restore backup. it only restores it through the wipe efs process, which i cannot apply after the unknown baseband.
and the .tar backup which created does not have an efs.img.ext* file which i need.
it only has nvrebuild1 and 2 files
please help.

Pretty sure you can write the QCN that was backed up. I'm pretty sure your efs folder/partition is fine. I've seen phones with NO efs folder and they work fine. This isn't the days of the S2 where your EFS really was in the EFS partition folder. Now they're spread across 3 partitions that have absolutely nothing to do with the EFS partition/folder. Try writing your QCN. If that doesnt work, I have a homebrew surprise that might fix the issue (an adb script).

i fixed that,
i created a backup from g900f includes this
/modem
/efs
/nvrebuild1
/nvrebuild2
i wrote it to the broken one
i got modem warning at boot up
i flashed stock rom
then i got working baseband but with a restart problem for unauthorized something ..
then i flashed back the backup files created by z3x using odin, which contains nvrebuild1 and nvrebuild2
now phone back to the original status with original imei and network locked.
