Hi XDA. I just flashed a custom ROM to my Galaxy S6 G920S with stock ROM G920SKSU3DPK2.
Custom ROM flashing goes well but when I decided to go back to stock (I don't like some of the features of the custom ROM), I accidentally flashed G920SKSU3DPAC which is older release. When the phone boots up, SIM card no longer detected and IMEI gone, Baseband not available. Can I still bring back my IMEI?

Let's make this story short. I rooted my Vibrant, then I flashed custom ROM (ICS Passion) but after that there is no baseband, IMEI on system info about the phone.Also sim card isn't detectable(no service). My biggest mistake is that I didn't do efs backup.
So now, only solution is to flash to stock ROM (2.1) with ODIN?
I also have problem with my usb port so I'm wondering is there any way for flash to stock ROM without using ODIN?
THanks
OOOKAAAYY.....after many months of flashing and downloading files. I managed to get AT&T firmware, and modem onto my SPRINT SPH-L720T. I believe it happened after I got rid of anything carrier based, and flashed a google based rom, and then flashed AT&T firmware, CSC file, Modem, and Kernel. Heres the catch...when I did this I lost root and went back to stock recovery. It takes a while to boot, but the at&t firmware loads even with all the AT&T bloat apps, However my baseband is still stuck on L720TVPUBNC6 which is the baseband for sprint galaxy s4. Originally I upgraded it when it still had sprint firmware all the way to android 4.4, but after all the flashing to KK Rom, Cynanongenmod, liquidsmooth etc until the present I cannot change the baseband even when I flash with odin or from recovery mode on the sd card. Do I need to reacquire root , and a custom recovery to do this? Ive spent so many days, and hours doing this, and im finally on the edge of converting this phone completely to AT&T from sprint. My wifi also does not work which I believe is related to to mismatched baseband. Can anyone help?

Im installed a custom rom (CM13 6.0) For My Galaxy J7 (SM-J700F) After that my IMEI had changed and i can't use my netword and calls again .
how i restore my old IMEI again ?!
I think if you flash the stock rom your old imei will be back
If possible Plz Find another J7 which have custom recovery and backup his efs than put it folder from his phone to ur phone In backup folder than restore it...
I think its backur network....
Note: Do it first before Flash any rom... Backup all files with twrp
Same Problem here
Hi I'm using the Galaxy J700H phone its like 2mos old, and have the exact same problem, so please can someone help? My problem is, I think also is my IMEI number? When i dialed *#06# on my phone my IMEI is 350000000006 and FTW that's not even my IMEI anymore, I have the original IMEI number here backed up but i tried everything, step by step. But sadly nothing worked out. I used this sim card in all of my phones and lastly when i wiped out my phone and flashed custom rom in it, then this happened, then i decided to flash the stock rom that has been downloaded from the sammbobile.com website, after that nothing happened. My phone always displays EMERGENCY CALLS ONLY.. pls help
hi, i got problem...i had stock oreo oficiall without any mods and i decied to flash some custom rom like s9 port teamexyking, now i cant detect any sim card on any custom rom....some help??? i flashed modem and bl and still nothing... looking for solutions, mb some1 can help..ty
I had the same issue and I think it was the same ROM, but it only happened after a day.
Re-flashing the ROM via a dirty flash didn't make a difference.
In the end I just changed ROM because I didn't want to spend too much time on it which worked, so it hasn't done any permanent damage.

Have u checked your imei number or baseband version ???
If baseband version is unknown or imei is null so u can't get netwrok
Or u have damaged your efc partition???
If u have none of this above problem
Than u should check your sim tray or go back to official stock firmware because I'm also on tha same rom by teamexykings and it's working superb
@up indeed my friend, i flashed official latest oreo xeo and its works... Ty for ur help guys
So, I bought a refurbished unlocked S6 the other day (SM-G920F). I didn't note down the original region on the original TouchWiz, but I do know that it was on 5.1.1. At this point the phone was completely normal. I went to install twrp, which went ok, but after installing twrp, the phone would no longer boot, even though I made no modifications to the stock rom. I then decided to format and install a newer TouchWiz room, which required I also install a "kernel". After installing the kernel, all x axis inputs were inverted and the phone still would not boot. I then decided just to download a France region stock rom for the G920F and flashed it via twrp, which was successful. But for some reason the x axis is still inverted and my imei is completely incorrect. I have tried to use the dialer code, but it does not work because of no network connection. I cannot connect to a cellular network because Android has the wrong imei number. I have also tried to use both kies and smart switch but my device will not show up. I also tried an older version of smart switch for the initialization feature, but it says that the g920f firmware is not supported. If anyone can help me try to at least get my s6 back to stock rom without these issues I'd really appreciate it. Thanks!
