T-mobile says my number on this new device should have being working for at least 45 days or so with refill balance. My cycle ended after 15 days of purchase and I really didnt see any reason to refill it as I was no more in usa. And no, I dont want to CHANGE my IMEI, only want to restore my own IMEI only. I am not sure if my EFS partition is corrupted, because I rooted my phone tried to backup EFS folder now (I know its too late but still), deleted it and rebooted (as a few threads suggested it would regenerate nv data files), but neither did I see any nv files when I did a back up now, nor after I rebooted. When I rebooted, the EFS folder did regenerate but there were no nv files in there. Also, after deleting EFS and regeneration the serial number was corrupted, but when I restored my backup, the serial number showed up correctly again. Also my current backup contains the imei folder with mps.code_bat file. I noticed that even imei folder was not regenerated on deletion of EFS and reboot. I somehow have the feeling that this is still indicating that my original EFS folder is still present (though I may be wrong, because I dont know). But my concern is the nv data files, which I dont see anywhere. I did come across several threads about imei corruption and restoration, but the only one I didnt come across was T-mobile SGH-M919 with stock android 4.3. I am wondering if this has some different file storage structure for imei (which again I dont know). At this point I am concerned about getting back my imei, I can get the unlock code from some reputed paid service again. I understand that open discussion about imei involving anything CHANGING IMEI is not allowed here. If anyone could just help me out restoring my original imei, even by pm, I would really appreciate it. I just dont want to throw away the phone and lose my money because of the error done by repair shop.
First off....the enter key is your friend. Hit it every so often when typing giant blocks of text like that.

Second, since your IMEI has been deleted, you now have to change it, even if you just want to change it back to what it was before. The process to fix it now is what can't be discussed here.

IF you had backed up your EFS partition, then it would be as simple as restoring it in recovery. That's all well and good. But your IMEI is now 0, so you have to change it to what it was.

But all that aside, you went to a store and they broke it. Take it back there and raise holy hell until they fix it for you or buy you a new one. I know consumer protections are stronger in some countries than others, but wherever you are, yelling and screaming is a universal language.

Can someone at least tell me what file in T-Mobile Galaxy S4 SGH-M919 Stock Android 4.3 contains imei number, so at least I know if I even have that file or not or whether it is missing? Thanks.

Whether your file is missing, modified, or corrupted, you need your /efs folder to restore it. You do not have have a nandroid backup or the /efs folder. I am sorry but the simplest we can put it without sounding harsh, you're screwed. You need to request the local shop give you a replacement phone or credit to get a new one.

Update: I went back to the shop and told them "You broke it, you fix it, I don't know how and I don't care, you gotta fix it". They managed to fix the imei number somehow. Regarding unlock, the shop ended buying the unlock code themselves. They mentioned that no one is able to unlock T-Mobile S4 with Stock 4.3 as of now without unlock code, unless they have some device like Z3x box. The phone is finally unlocked and working fine on my network. (YES, A HUGE HUGE RELIEF).

Everything is fine, except for 2 issues.

1. I want to backup my EFS folder so that I don't enter into trouble with IMEI again. I tried EFS Pro, but its not working. All I see is "'Initializing ADB server..." (the phone is rooted, usb debugging mode enabled, and supersu permission granted when prompted). I also tried to backup using Andromizer, but it says "Notification: File not found in /storage/emulated/0/Amdromizer/efs/efs.img". What is my best option as of now to backup and store my imei safely somewhere?

2. I am having issues with Wi-Fi. Before the shop flashed my phone, it was all good, but now it doesn't auto-connect to my home Wi-Fi anymore. Everytime I reboot or get out of range, I have to manually select my home network everytime and also enter the password everytime. Nothing has changed on my router. The other Samsung device that I have still auto-connects to my home Wi-Fi as usual. How can I fix this?

Thanks.

For the efs you can back it up using recovery. Just boot to recovery and its one of the options in the backup menu. The resulting file will be like a few KB. Its supposed to be small. Dont worry

Sent from your phone. You should be more careful where you leave that thing.
