Help with IMEI on s7 edge - Samsung Galaxy S7 Edge Questions and Answers

Hello guys. I have a s7 edge G935F and I can't figure the solution to this problem. I installed the new oreo ROM and everything works fine except I have no network and my IMEI is gone. I tried to reinstall the official 7.0 ROM but odin works only if I don't install the bootloader. Now I have installed the official 7.0 ROM but can't figure out how to fix the IMEI. When I root the phone, at the startup it gives me the mesage that I have to factory reset it because I changed the OS and can't do anything else. I would much apreciate your advice because I am desperate already to find a solution. have a nice day

Fingerprint and network dead after flashing (so-called) stock rom

I've flashed 139-63 stock rom and after that, fingerprint and both sim's are not detected by the OS. No network (wifi works), no fingerprint.
Tried many roms, still no luck. Is there any one who experienced this problem and fixed it? Please help me. :crying:
Likely need to flash ROM/firmware specific to your model number. Maybe someone here can post it if you provide model
i am also facing this problem i have also tried many firmware which say its for moto g4 plus xt1643 huh but non of them works then i restore my backup now and phone is working but still no fingerprint because its says it is moto g4 in model number
XT1643. Tried every firmware available on internet. No luck.
I have sent my phone to the service center after relocking bootloader. They are trying for a board replacement. I don't what happened to the phone. There was no problem when flashed the firmware for 2-3 times. Suddenly something went wrong. Kindly let me know when you get a fix for it.

Please flash this rom https://drive.google.com/file/d/0B1N6dGU7FEXsSjR3QUtsRU1RTVk/view
This is correct Rom for Indian Varient XT1643, I got my everything working.
Downloaded firmware, flashed using mfastboot, still no luck. Fingerprint is absent from the setup wizard and in the OS, and one IMEI is available. Not both.
Have you faced this issue?

Help(urgent), updated G900P to Nougat, all is fine but no network signal

thank you for help.
I bought it today due to previous phone failure, it had LL5.0, I updated it to MM6.01 updating the bootloader before and then the rom, now I loaded Nougat by twrp.. all is fine except no network signal. I think the problem is with baseband, my version is G900PVPS3CPK1. What can I install to have it working?
I'm without phone, I pray someone to help me quickly, thank you
the baseband works ony in LL 5.0 actually on stock ROM G900PVPU3BOK4_G900PSPT3BOK4_G900PVPU3BOK4_HOME.tar but it boring asking to update to MM, if I update no network connection.
I was on 7.1.2 Resurrection, it works great extept baseband, guys said me it is projected for G900F.. but while I tried I had the MM bootload where baseband doesn't work. I dubt I can use the bootloader of LL that works..
You need to flash a baseband that was intended for nougat. I have. G900p (sprint s5) running on a att network. Im running crdroid 7.1.2 my sim works great ... You need to reflash stock rom and either leave it alone or do some reading before you just start flashing stuff you dont understand ....
thank you for help, mya you kindly suggest me a stock rom that worked for you?
I've solved the problem, but not really happy how.. https://forum.xda-developers.com/showthread.php?t=3698397
Found Resurrection remix that works great on G900P, and used Lollipop AO (they said last of LL 5.0) as boot loader. When I used the MM bootloader the baseband wasn't working, as well when I left the stock AO 5.0 update itself by internet to MM.. several updates insluding baseband to the most recent releases and network was off..
THe problem is intriguing, why this happens?

Hi mate, kindly read the message above, thanks
solved with some pain, needed to pit the phone and flash the stock MM, then boot to check the baseband, then flash twrp and RR+gapps. All info here:

Downgrade to 6.0 from 7.0

Hello, i'm new to this forum and this phone (SM- G928F). Can someone tell me or link me on how to downgrade through Odin to 6.0 ? A colleague of mine had bootlooped his phone and forgot his account, the phone stuck on FRP and he doesn't remember it. I tried to downgrade but Odin fails when I try to.
Thanks in advance !

error updating s7 edge 935t unlocked

hey there,i have unlocked variant of s7 edge 935t ,i got it unlocked online,while updating it from settings i get an error"the os on ur device is modified in unauthorized way.Try downloading soft. update using Smart Switch.""
someone help me out what if i update it using smartswitch can lock my device again??
my device is rooted. help me ASAP:highfive::highfive::highfive:
If the phone has been sim unlocked, it will stay that way. On the other hand, if you flash/install stock firmware you might loose root.
Bro thnx for effort..but you replied late... i already flashed stock rom and everything is fine..no issue,and also update is working fine for me.
