Hello, i have problem with my S7 Edge. Yesterday I uninstalled some of the system apps like skype, whatsapp etc. And then my phone got into a bootloop. I did recovery from TWRP, but now my network doesn't work. It says "unknown imei" and "unknown baseband" in "about" settings. I had efs backup in twrp, and when I recover it, it says completed, no errors. But it doesn't work anyway. Also, I cannot install stock rom via Odin, there is error: "sw rev check fail device 3 binary 2".
Can anyone help me?
Some info:
I used stock oreo rom (XEO) with magisk and SuperStock kernel.

Hello guys,
I need extremely technical help as no longer know what to do.
I have a Galaxy S7 Edge device, which installed the rom BobCat and everything went well until then.
Later I decided to install another rom to test KingRom that left me unsatisfied, because I thought it had some bugs. Had the TWRP 3.0.0 recovery and decided to upgrade to 3.0.2, everything went well.
At one point I do not remember when or how if was when install back, downgrade to TWRP3.0.0, I do not remember if it was via Odin or TWRP, it happens that the installation stopped halfway. Then unplug the device, restarted in recovery mode and got the following message "E: falied to mount EFS (Invalid Argumen)", I could not restart the device (Boot Loop, and stucked at Samsung Logo) except in Recovery Mode, which also made to stay without IMEI number and Serial Number.
I googled until I came to this tutorial:
http://forum.xda-developers.com/s7-e...ssues-t3379516
I followed all the steps explained, I back up EFS_backup and RADIO_bakcup partitions.
Installed FACTORY BINARY G935, everything went well. After restarted, already had the correct IMEI number but still did not present the S / N.
After all that, i tried to install Stock Firmware via Odin, from here started the problems that could not solve.
In the first attempt Odin stucked in "System" (also used the PIT file with the same CSC ... .i do not know if I was right using PIT?). Restarted the device forcibly, entered the stock Recovery, did a complete wipe and always get this message "E: falied to mount System (Invalid argument), I returned to install Factory Binary, then reboot in Recovery and the same message no longer appeared.
Again I try to install the Stock Firmware and Odin always stucks in System, or NAND writing, or Partition, etc. I've tried various Stock Firmware, with and without PIT files, always without success.
Only Factory Binary that successfully installs. The TWRP via Odin also but when device restarts to enter Recovery Mode always get the message at the top of the display:
"Recovery image signature check Fail"
"Reboot to avoid Warranty bit set."
1. Does the partitions are in good shape? how can I check it?
2- I did good or bad using PIT file?
3- Does the problem is running Windows XP through a Virtual Machine?
4 What else can I do?
In all actions used and am using a Macbook 4.1, OsX Lion 10.7.5, Odin 3.11 Windows XP Professional 32bit through Oracle VM VirtualBox 3.4.38
Device:
Galaxy S7 Edge (SM-G935F) CSC = SWC SwissCom
1st Original Firmware: (I guess was 1?) G935FXXS1APG5_G935FVFG1APF3_SWC
Need help Please
Thank you so very much!
I switched between a few ROMs but now I'm getting the issues "CSC code unknown, no device root key, no ENG binary".
Meanwhile the TWRP restore isn't fully working either as it will work but gives constant messages about "unknown partition" or something and "partition not found".
Any ideas?

You need to flash stock firmware with "PIT FILE" check "repartition & nand eraseall" in odin options

After flash make factory reset from stock recovery after Flash firmware.

I really need help, please.
I am facing same problem with my s7 edge g935fd. But in my case i lost imei of both sim cards & lost baseband version. I tried z3x samsung tool. But i didn't found model g935fd there.
Waiting for help
I am having the same problem with an S7 (G930V). During one of the re-flashes, I was able to install the Samsung Product Info App. The CSC product code came up as blank. Not sure if this is normal for this state. Any leads would be appreciated.
I installed TWRP so i could use Magisk and pass safetynet so i could use GooglePay. However during the process i mustve messed up. Currently i can enter TWRP aswell as Download mode however Odin gives the the error "Complete(Write) operation failed." and my phone says "SW REV CHECK FAIL DEVICE 3, BINARY 1"
My device is Galaxy S8 G950F UK H3G, i have checked that i am flashing the right firmware. In addition to this, when i try to boot normally im stuck on the "Samsung Galaxy S8" Boot screen.
Anyhelp would be much appreciated, i just want to get my phone working again.
Any reassurance with drivers and links to specific drivers would be useful, i installed all the ones i could find
Seems like your firmware you are trying to flash is older than the bootloader... try to flash the latest firmware and reply.

Yes thats what this error means your bootloader is updated and you are flashing older firmware than the device currently has by the device 3 I would assume your device is updated to revision 3 of firmware
Backstory:
Received the message "Custom binary blocked by FRP lock" when restarting my phone. I had a custom ROM installed so this was probably why, but I had flashed no-verity-opt-encrypt previously so I don't know why I randomly got this message.
Tried to flash the latest Android 8.0.0 stock firmware from sammobile, successfully flashed through Odin but when the phone boots it keeps looping into recovery, followed by "No command".
When I try to access the recovery settings by pressing power+up it comes with:
fail to open recovery_cause(No such file or directory)#
Reboot Recovery Cause is [UNKNOWN]# No Support SINGLE-SKU
Along with a bunch of lines saying failed to mount /system and dm-verity failed.
I've tried flashing many different stock ROMs but only the factory binary combination ROM is able to boot up. Therefore, I cannot turn off FRP lock. I am struggling to find out why, even though Odin successfully flashed the whole stock BL, AP, CP and CSC, the recovery cannot be opened.
Any ideas would be greatly appreciated.
Edit: Managed to fix it through a YouTube video by Mr.Lee
Try downgrading to nougat or marshmallow. That should remove FRP.

I've tried but I cannot find any marshmallow/nougat version which does not result in a SW REV CHECK FAIL error, my kernel only accepts Oreo or higher it seems.
