So i've had a rough couple of days with my S7. It all started when I used fdisk on /dev/block/sda thinking it was my usb. The phone froze and so it rebooted it, i would bring me directly to the download screen where i was able to install twrp.
Then I had problems with the /efs/ folder mounting, and like a noodle, i wiped it without a backup. So once i booted the phone. I had no service provider. I spent all day trying to figure that out.
Next I tried to install my stock firmware which always worked in the past. At this point i kept getting "dm-verifty" errors. TWRP bypassed it so i tried to flash it again, only to notice FRP lock was turned on on it's own. So let me sum it up.
I can't boot with stock firmware, i tried multiple all leading to "dm-verity error" "No DRK"
I can't install TWRP because FRP is ON.
Even if i figure this out, i have to deal with my imei and efs problems after. I read about Combination but Odin seems to refuse it.
I haven't even had the phone for a month so I may be able to return it but i doubt it because my void is 1 (0x500), which looks bad so.. :laugh:
If anyone can help me i would greatly appreciate it, thanks in advance.

I want to start out stating that i am very familiar with android's but have never experienced anything like this.
The first thing I tried was to oem unlock it from fastboot, which it claimed to do however i am skeptical as nothing else seems to stick, attempted to install cwm and TWRP neither with any success, even though it says the action was performed successfully.
The strangest thing is that i deleted all the apps on the device from settings/app, but when i rebooted my device they all came back!
All i wanted to do was do a factory reset, which also claims to finish successfully but after rebooting from recovery mode, i am back where i started.
App Updates also do not work as every time the tablet reboots, the apps have to be re-updated.
Its like the tablet is stuck in a read only state and when it reboots all changes are lost.
Like i said, this thing is acting weird and i have no idea where to go from here. Any help would be greatly appreciated!
[Update: Tried RSDLite, same results, Result is PASS however after system reboot everything is the same.]
Another update, tried downloading HWI69 which is the stock rom, tried to fastboot each image but nothing sticks even though it seems to say it writes it to the system. I'm starting to think the NAND memory is locked up and cannot be written to anymore if that's even a possibility.
BUMP
Where to start...
First, as a disclaimer, I may use language or terms that sound noobish. I have rooted and run custom ROMs on several devices in the past, however generally when I get a ROM I like I stick with it, so I'm not constantly tinkering. I've done my best to search and find solutions so please go easy on me.
17 days ago I was running stock 4.3 on my SGNII when the battery died. Upon charging I found I was stuck in bootloop and had a bad /efs mount. I searched and searched and spent around 15 hours trying this and that but to no avail. I finally threw my hands in the air and got ahold of Josh at mobiletechvideos and he was able to fix the efs mount issue. However, he left me in factory mode which required me to root to get out of, and once I did this I was unable to activate data on my carrier (Ting). I was so happy to have my phone "back" though that I used it like this for 4 or 5 days. I could get on wifi and I could call and send text messages. I had been off the grid so this felt like something I'd fix fully later.
Well I kept reading and found "fix" after "fix", flashed this and that and still no dice. FINALLY, last night, I found this thread: http://forum.xda-developers.com/showthread.php?t=2086769 which helped immensely. I was able to get TWRP flashed by unchecking the "auto-reboot" option in Odin and pulling the battery after the update took, and via TWRP I was able to install the ROM. I booted up, the device activated, I was running 4.1.2, I made and received some calls, the birds were chirping, the air was sweet...
I had struggled for so long and I had finally achieved success! Then, for seemingly no reason at all, I accepted an OTA update which bricked my Note2. Devastation.
The current state of things...
* Cannot get past the initial "Samsung Galaxy Note 2" screen
* Cannot boot into recovery
* I CAN get into dl mode,
* but, I CANNOT successfully flash anything. TWRP will flash like it took, but upon reboot I'm not able to boot into it. I'm also able to flash a ROM but it fails when it gets to sbin, and upon rebooting I'm greeted by the screen "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again."
When I try to use Kies it doesn't find the device. I've installed all of the most recent drivers and I'm running Kies as administrator. I select Tools > Emergency Firmware Recovery, THEN connect my device as instructed.
I'm at the apex of frustration. I beg thee to help!!
Hello Guys,
I'm back again (I posted about this issue about 6-9 months ago, a couple users tried their best to help me with it, since than I haven't had any time to fix this issue).
History:
1. Brand new FRD-L14, bought the phone, used it for 1/2 day, fell, cracked screen, replaced it.
2. The phone worked there after, but the OS read "NRM-Test Keys", anyways since I had TWRP installed at that time, tried several different roll backs and such to install a full OS, never worked
3. I did encounter a problem where the fastboot screen would read "PHone Unlocked", but "FRP Locked", at which time I was unable to install anything the error when going through Adb/Fastboot would be "Error: Command No Allowed", a experienced user here did fix it remotely for me, no idea how, but anyways it worked, so back to #2
4. Now the phone has FRP Locked again. So I can get into fastboot, and stock recovery (which doesn't work, states device is unsupported), cannot instal TWRP as FRP is locked
What I need help with is to get rid of this dam FRP Locked issue. I don't understand why it keeps coming back despite me not logging in/putting in credentials when I install the OS.
As I am in the US, Huawei has no authorized repair centers. What a waste!
Any help or suggestions are welcome. Thanks.

Can you get to download mode for the sd card firmware update?
I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
Okay. I was messing around with my firmware which I've done in the past. I've had a few problems then due to my phone model being obscure (Samsung Galaxy S6: SM-S906L). I've always had a copy of the firmware saved to my computer in the event of a bootloop or a similar issue, I figured I could just flash it with Odin to fix it. I have also done this in the past. After accidently wiping my phone, I went to re-install Magisk, but noticed my phone trying to push an update. I let it go through without much though and after it finished saw it didn't change much. I carried on with re-installing Magisk when I figured I might as well fix some problems I had with booting the phone (I would have to boot it into download mode then recovery to get it out of a bootloop each time I turned it off). I carried on with flashing my saved firmware to fix the problem. Everything flashed fine except the bootloader. It's come to my understanding now that because I let the update carry through with my phone, my saved firmware is no longer compatiable dispite the fact that it didn't change my android version. So now I have a bootloader installed that is meant for a higher update without my known ability to downgrade. Due to the obscurity of my phone model, I can't find anything to bring my firmware up to what my bootloader is at. So now my phone is stuck in a bootloop with the ability to access download mode, but recovery mode simply gives me a "recovery is not seandroid enforcing" error. I would greatly appreciate it if someone has any advise they could give me.
