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.

I have a stock 5.0.1 model N910F and tried updating to 5.1.1 using Odin, however I got an "invalid ext4 image" error. When I took the battery out and tried rebooting it, it just showed a screen telling me to use emergency recovery mode in Kies however when trying to do that my device wouldn't show up in the menu. I then tried extracting the recovery file from the 5.1.1 tar file and flashing that but again it wouldn't work. I can still go into download mode, but my phone just won't boot. Now I'm trying to download another 5.1.1 file for my country from sammobile and seeing if that will work, but is there anything else I can do?
Edit: Nevermind, flash this and it worked.
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!
G935F FRP lock out of nowhere, "Device does not have DRK" after stock firmware flash
Hello. I and my friend have a lot of problems currently with the phone.
The phone had randomly thrown the FRP lock on, and it became unbootable. (gets stuck at logo and would tell that "custom binary locked by frp lock"). The phone previously had stock firmware.
The first fix we've attempted was to flash the stock Oreo firmware (G935FXXU2ERE8) via Odin. But after flashing, It got stuck at bootloader logo without any additional text this time.
Then we've tried to flash an older firmware (G935FXXU2DRC4), and then the phone started throwing the "Device does not have DRK" error.
After booting to recovery, it says "Please flash ENG binary then install DRK".
After reboot via recovery, it started throwing a dm-verity error (0x02).
After some Googling I've found out that It's fixable with a boot file flash. But I couldn't find one for current firmware. Maybe we could just use combination sboot file (pakfirmware.com/2017/11/samsung-frp-samsung-s7-edge-g935f-sboot-combination-file), or should I find one that's specific to the current firmware?
So I have a S8 (SM-G950FD Brazilian unlocked) and it freaked out while updating to the latest firmware. It boots to a screen saying "codification failed" (I translated, it may not say that in an English configured device) and asks for a factory reset wich does nothing. I tried flashing the latest firmware with Odin and nothing.
So while researching I came across combination files, so I downloaded the one for the right binary (5) but it spits out the error "custom binary blocked by frp lock" when flashing with Odin and now I'm stuck.
I would post photos with all the device information in both recovery and download mode with the hope it may show something I don't see but unfortunately, I'm a new user and therefore not able to.
I have a co-worker's G930V that decided it wanted to only boot to the 'no command' recovery thing (not the menu, just blue with no command'), it's devolved to the point where he doesn't care about the data on it, just trying to get it working.
Info:
It's FRP locked (he knows the login, so this isn't important)
It's on binary 10 (can ONLY flash firmware CSF2 as far as I can tell)
Things I've tried and outcomes
Smartswitch: 'unsupported device'
Verizon's tool: 'Unsupport dev_type'
Odin flashing BL/AP/CP/CSC anything other than CSF2: 'SW REV CHECK FAIL'
Odin flashing BL/AP/CP/CSC for CSF2: 'recovery booting' followed by it rebooting and sometimes getting to a screen with a percentage bar that just says 'Error' (attached)
Odin flashing PIT/BL/AP/CP/CSC: same as non put odin
Odin flashing PIT/BL/AP/CP/CSC and NAND ERASE: same thing
I was able to get it to get to the encryption failed screen once by flashing just AP after a NAND ERASE PIT/BL/AP/CP/CSC.
I also got it to show "Custom Binary blocked by SECURE BOOT' by only flashing official firmware...
Update: There are other weird things that happen... I got odin to flash the latest G930U firmware and the same thing happens, I've also seen the grey circle with a lightning bolt screen leading me to believe its a battery issue.
IT WAS A BATTERY ISSUE, Tested with an S6 battery and once I flashed the Verizon firmware it booted right up.
