no avail
You need to take it to an engineer, a flashing box is required to write a new IMEI cert for the device!

PREREQUISITES OF FLASHING CUSTOM ROM
1. Root your device
2. Flash TWRP(Recommended) or Latest Philz CWM Recovery
3. Do a NANDROID Backup which backs up System, Cache , EFS , etc

then you can go ahead to do any FLASHING of custom roms.

Idiots just spoiling phones in the name of using custom roms, its totally pointless and worthless. Just enjoy your phone as it is.
You don't refer us to idiots, we simply know how to make our device do what we want, not what the manufacturer says it should.

You cant enjoy your device as is like I do mine! #Fact

why will you even flash custom rom on galaxy s7....is the ui not beautiful enough ...now see what u av done to urself ........

i know the problem ....it has happened to me one time when i was flashing rom in tecno ...

the problem is ur #navram (a hidden folder inside ur system folder that controls network and imel).... its has been corrupted in the process of flashing....
...

to solve it u will have to flash original samsung s7 rom back to ur phone..... and mk sure u flash it with sp flash tool ......not cwm or twrp.....


and next time don't forget to backup ur original rom before ur flash any new one

Flashing Custom ROM is very necessary... the S7 UI is shite ✔
Re: SOLVED: I Flashed Custom Rom On My Samsung S7 Now No Network by nani667: 3:31pm On Sep 11
OP download the Correct stock Rom for your Device and flash with Odin... that should most likely solve your issue ... although you should have backed up your EFS first with the recovery before you flashed the Custom ROM...

If you have Telegram app installed drop your username or Contact and I'll add you to the Samsung Galaxy Telegram group...You will get all the help you need there... including the Links to The Stock ROMs and other tools you may need ✔

Lol, that's a very weak defence. But in any case if you feel its worth risking a very expensive phone just to get a different appearance then go ahead and enjoy yourself. Just don't come here crying to us like this boy here if you mess your sh*t up.

Xda is the best place for help or you can try reddit, telegrams or tapatalk search Samsung s7 thread. Although you have the the correct firmware it will revive the network but if you don't, you have to find some who backup his nvrum and port it using efs developers tool. Can be find on xda. Sorry i cant help with links

Which version of Android did the device come with?
Go to sammobile.com and download the rom for your brand and make sure you download for your region, if it is unbranded, download for either Nigeria firmware ECT or Morocco, what happened to you is that your efs folder is likely corrupted. You can also get z3x tool box if you are familiar with flashing
