After flashing firmware with QFIL I have this issue. I have no IMEI and no baseband installed. I don't know why. Maybe there were some problems during flashing or there were an erasing of the EFS partition with modem files. It is not possible to use the SIM card because it isn't recognized from the phone. Please help, I followed each guide on this forum, but nothing worked for me.

i am a international galaxy s3 user I9300, i have lost my efs folder while flashing ROM, i messed up everything . i have tried flashing with Odin also does not work, it passes but does not boot stucked on the Samsung logo. when i put it on recovery mode it shows efs failed to mount. while reading some thread here i found that it can be recovered by flashing through flash box, so will the handset be recovered by flashing through flash box like z3a... plz helppp..

Unless you have an efs backup, or flashing an EMG modem enables your efs partition to be read again, then you are basically screwed and need a service centre.
I tried unlocking my bootloader unofficially and bricked it, then trying to fix it I may have accidentally wiped all my partitions.
Luckily I followed the guide and unbricked it via the 'teardown' method, flashed V7.2.3.0.LHOCNDA with MI flash and it is now up and running again.
The issue now is I cannot turn on Wi-Fi and the phone cannot detect my sim card. Baseband is unknown and i have no iemi.
I have flashed several different versions and it is still the same.
I am now rooted and have twrp recovery
Could wiping all the partitions do this, is it reversible?
BTW: it a 16gb Pro from china if that helps

If u had previously backed up efs then restore it, if not then head over to miui.en forum there is a tutorial on how to restore imei no.
After having my phone in a bootloop, i figured that my /efs folder was corrupted as it won't mount, so I tried the fix in a website that used adb with mk2fs command thing (I don't know what it is so I just followed the instructions). and I don't have any backups of the /efs folder. I know my IMEI code from the back of the battery in my phone. I've tried most solutions here including QPST, reverting to stock, and using root explorer to transfer the nv_data (I don't have the .nv_data file with the .). I'm currently running Paranoid Android ROM of android 6.0.1.
Did you try flashing a stock rom to see if that solves the problem?
Flash Modem DDEMG2.zip to get your imei. Then flash Patched_XXUGMK6_modem.zip to get mobile signal
Hello,
After a fail flash custom rom, my phone got bricked. Somehow, i recovered it.
But now, i'm facing two major issues : No IMEI, No BaseBand (Wi-Fi is still working.)
I've tried every single post concerning : Restoring Imei and Restoring EFS partition.
(When i tried to restore the EFS partition following this guide : https://forum.xda-developers.com/redmi-note-3/how-to/flash-recover-efs-snapdragon-t3406789 . It requested me a password after booting)
Please help me, it'll save my life :crying:
