Hy guys ,I bought s7 edge G935fd few days ago and it had custom rom ,so I decided to install stock rom by odin but after flashing stock rom 8.1 it gave network problem, it was not showing my networks of both sims ,so I contacted a shopkeeper who says it has security patch issue and it will solved by 1500 Pakistani Rupees, I pay that now my phone is ok
My Questions are......
1...If I flash other firmware ( stock or custom),will it gave again network problem???
2....If I make backup using twrp ,will that work again after flashing ???
3......Is there any procedure to install security patch without any box or payment???
Your efs partition is corrupted or removed flashing full firmware does not restore efs since efs is not in firmware packages and they are different for each phone. Anf this does not have anything to do with security patches. If you backup everything via twrp you should be fine
Thanks
Thank you sir,
I made backup by twrp ,may I install any other Rom ???
And if I still got network issue, then my backup will useable??
Anyone there to help me ???

I have SM-G935S (SKTelecom Korea) and have been trying to improve battery life by using custom ROM. The installation is a success, but it makes my phone cannot use mobile data connection. I have been trying RENOVATE 4.0, SupermanROM, and KingROM but all have the same result. Are my device not compatible with those ROM or any mistake and fix that you can point it out to me? I'll be thankful for your help.
If the imei still intact, there's hope. Try flashing original rom. If not, service center is your only option.
Try updating Boot loader and Modem before installing the recent custom ROMs. Or use ROMs that have the Auto-Bootloader and Modem update. Check APN settings for Your network.
I have the same issue but for a G935F
Did you solve the problem?
It happened to me also. I have g935f. Only thing that works for me is to install csc after installing the rom. So first install rom then let it boot. after boot before settings go back to recovery and then install your csc and then boot up and do your settings. Good luck.
I flashed the combination of binary U2 to restore my i Mei and drk error but it shows modem crash in the binary mode and cp crash mode.
I hope someone can give me a solution that's useful and it's okay for me to pay by PayPal after it has been fixed.
The following is the message I sent to cubz but he doesn't seem to be free to active these days so I hope anyone else can help me.

{{{{Hi, I've seen many posts in the xda and many people refer the solutions and fix advice to your name on comment so I think you will be the only one who can help with my issue.
Firstly, I had my S7 edge flashed with many roms before and flashed with odin ( with sim card always, not knowing if this is a major problem), but after once I did after using the encryption on the S7 edge with the lineage OS ( the 8.1.0 one in Feburary), I tried to flash with other rom without decrypted it and flashed fail. ( roms are all android 7.0 and 7.1.2)
Since then, I tried to flash other rom (7.0 like superman rom or rom from SAC) but still losing cellunar signal. then I tried to flash the original android 6.0 official firmware through odin but it failed on the step which shows DRK error on the samsung official 6.0 recovery.
After reading your post on how to fix DRK error, I tried the method but maybe because of I don't really know the steps or how to restore on the binary factory firmware, it boots up but still lose of IMEI and cellunar signal.
After the android 8.0 is released officially, I flashed the official rom and I tried using the U2 version of bootloader binary factory which you shared, but same problem happens and I also tried the V5.7 devbase rom and same.
Very seldomly the baseband and imei will show as normal and having cellunar signal but not long and after I reboot will gone to unkonwn to the imei and baseband and show as 'no sim card'. ( there was one time that I ticked clear efs on odin then i lost the imei. But after i flashed the binary firmware, imei show unknown in the binary firmware mode but when i flashed back the devbase rom with twrp, the situation of mostly showing unkonwn of baseband and imei happens but very seldomly it will load as normal which they are shown correctly)
*Btw the first flash the U2 binary firmware( Im using the U2 version because my bootloader has been updated to the oreo one), it boots into the screen that shows cp upload or modem upload error? page , then i flash again but with efs clear which was what happened as I mentioned before. ( thats the only time I ticked EFS clear as i can remember)
Dear CuBz90:
I really hope that my s7 edge can be fixed because I have had it for more than two years already and it was the first time that i buy a phone using my own my money but not my parents, I hope you can help me with this issue.
Thank you very much!!!
( its okay if I have to pay( its okay through paypal) after its fixed, but hopefully not too much)}}}}

I was installing a custom rom on My J5 prime through TWRP recovery.
I forgot to take backup of my efs file. now it is wiped and the phone is not showing imei number.
My calls are not working. The service centres are asking 5000 rs for changing the motherboard.
After Flashing the stock rom the phone is booting into recovery and saying DRK not installed.
I have even tried flashing combination files.
boot_eng files
Tried repair imei by Z3X. It does not work. saying security error(1)
Even tried flashing Cert file.
Tried Rooting the phone and then installing Xposed and changing imei by a module
Nothing is working please Someone help me.
Give me TWRP efs backup file or suggest me something that will help.

Hello, I wanted to know where I can get the firmware of the j730f / ds version 8.1 if possible, in the same way any other would work for me. To install via recovery or twrp, no Odin (damaged connector) ... greetings and sorry my probably wrong English
Hmmm
I understand your problem
I am not a pro, but have found some roms for you (install through TWRP) All are Custom Roms
Clean Pie
Clean Oreo
S9+ port rom oreo for j730x
Hope these will help you, But try at your own risk
Hello, i install all of these roms and my phome never find a sim card. I try to flash sboot files via odin 1000 times but not success. No sim card recognized and phone are dead. Anyone knows a solution?
hello, not sure if this is possible but needing to fix my efs partition as its corrupt, wrong serial and no imei number just 000's, i had a problem and updated my phone to the lastest stock firmware. Recently put custom rom back on. If any can help that would be great, thanks
You can't.. without matching binary combination rom and efs backup. Sadly, latest combination roms aren't available for s7 series.
