I've purchased 12 of these Tablets for my company. Out of the box they were android 6.0, as soon as we connected them to WiFi the 7.0 Update option came up so we updated all 12. We then loaded our Comodo MDM enrollment on them. Well Next time they rebooted 9 of them would not come up, they just sit at the samsung screen fading in and out. I went into recovery mode to try factory reset & wipe, I get the message that "mdm does not allow factory reset". So I tried resetting the cache which did nothing as well. So I loaded Odin and booted into odin mode tried to load a stock rom and I get the message that the device is in FRP mode and cannot load a custom image...
I have ALWAYS had droids and I favor Samsungs normally.... I have always rooted and unrooted every device I've ever had, but these have me stumped... I cannot get into USB debugging mode, I cannot get the things to boot at all. Every tutorial requires debugging mode. Samsung Business support is NO help at all. So I turn to the dark side... HELP!!!

Sounds to me like the problem isn't with Google's FRP lock but with the Comodo MDM enrollment. First thing I'd do is contact their tech support. The FRP lock doesn't prevent you from flashing a ROM with Odin. The FRP lock would just ask for the Google login and password on the first reboot. And I have seen other security apps blame the FRP lock for not allowing a ROM to flash via Odin.

I just got this phone alittle over a month ago. Today at work, my phone randomly shut down and started continuously restarting. The phone will vibrate and boot the logo, then turn into a black screen, vibrate again, and restart. I had not modified my device at all. Just downloaded your typical apps like anyone else. I already tried taking out the battery and letting it sit and booting in recovery mode and wiping the cache and restoring to factory settings. I also tried to use odin to flash what i think is my firmware onto the device. I wasn't able to figure out the firmware of the device before I did it so i sort of guessed based on the model. Though all i did for this is download what i thought was the firmware, put it in odin3.4, entered download mode and plugged my device in and let it download. I didnt do any rooting or enable debugging/disable debugging before i used odin. Did I miss a step? Does anyone have any suggestions of something I else do. I am so confused on how this happened to my phone!
update, read at the bottom.
Hi, I have a Samsung Galaxy Note 4 SM-910C which I have rooted after flashing a stock Samsung rom. If I recall correctly, I flashed a stock android 4 rom trough ODIN, did it a CF-Auto-Root and eventually updated android 5 through wifi (OTA). SuperSU was installed.
I have attempted to do a native full-disk encryption trough the default Security menu; the phone went into a black screen with a green outline android robot in the center, with no progress bar or text of any kind (I found the image online, but can't post it due to account lack of privilege) . It has been on this same screen for over 8 hours now.
The device was NOT in USB-debugging mode.
What are your suggestions? Should I try some kind of reset? Is it possible the process will resume and is taking so long due to the amount of files? Or I shouldn't expect it to work since I tried encrypting a rooted device?
I'm not worried about any files in it, but I'd like to make sure to be able to recover the phone without bricking it. I'll be leaving the phone plugged to the outlet and untouched for the foreseeable future...
Thank you very much.
UPDATE: I powered off the device (had to remove the battery) and when turned it on again was met with the "Encryption unsuccessful" screen. Then I turned it off and went into recovery mode by pressing and holding POWER+VOLUME UP+HOME. Even tough it displayed a warning - dm-verity verification failed - I chose wipe/factory reset and then rebooted the system and it seems to have worked fine. After the start splash screen and a notification that is was installing applications (bloatware), it brought me the Welcome to Samsung Galaxy configuration wizard.
Hello guys this is my first post.
I have a SM-G930V Verizon S7 that previously was in bootloop with OREO, but constantly rebooted at the beginning of the setup I mean when it says hello and so on.
I flashed Nougat without problems and booted normaly but then the FRP was doing his work, I could not boot since I didnt know the email or password.
I then flashed a file that I found to bypass FRP and succeded. I finally got it working very well.
After a while when I tried to clean bloatware suddenly frozen and then never booted again, I wanted to root but couldn´t.
NOW when I flash any ROM from Marshmellow , Nougat and Oreo, it says PASS in ODIN but I cannot enter the recovery.
Vol+, Home and Power gives me a blue line top left saying RECOVERY BOOTING..... then a blue screen saying ERASING... and the reboots again and again. The menu that I can get is the Maintenance Boot Mode (Vol- Power). This menu has 4 items:
1.Normanl Boot, 2.Factory Reset, 3.Safe Mode, 4.Power Down, and the only who works is power down.
I don´t know how much batery is left because I don´t know if in this menu or in download mode the battery charges.
I flashed the last OREO from SAMMOBILE, I also flashed the ROM wich I grabbed when using VZW Software Upgrade Assistant which supposed to be repairing the device but nothing whatsoever.
I don´t have any new ideas my head is full and hot now. PLEASE HELP will be appreciated.
1 year old S8 unlocked (SM-G950U1), stock software. Was running slow today, so I rebooted, and it now crashes almost instantly after showing "galaxy s8" on the boot screen, and just sits there with a slow blinking blue light.
Hard reboot just does the same thing. It won't go into recovery mode. I CAN get into software upload, so I tried flashing stock ROM back with Odin, but that fails, and now I get the "an error has occurred while updating the device software" error. Samsung Smart Switch isn't recognizing it as a supported device.
Can't get TWRP to install because FRP lock is on (and since I can't boot the phone, I don't think I can disable this).
So, am I stuck with a fancy brick?

No twrp for this device. You are probably flashing the wrong revision firmware. You need to flash equal to or greater than what's on the device
Also that same screen of error you can flash in Odin
Hi guys!
I've read tons of threads and guides on Google but nothing helped me to bring to life my Samsung Galaxy S8 Plus. After hours and hours of test and probes I surrender!
Basically I was using normally my phone and suddenly has power off and showing the Samsung Galaxy Logo continuously. I've force reboot it with vol down+pwr button and after some minutes restart normally again. After 5min again the boot loop and stuck there. Tried again to power it off but didn't work so I thought was the battery (because is 3yrs old with heavy use and months ago I had the screen flickering and a battery drain to zero). I opened the phone, unplug the battery and the power button (because I thought was the power button stucked as on my father phone). So after mounted all the stuff in their place I tried to boot it and suddenly start to work again! I've backup all my things rapidly but again power off by himself and this is the last time I see it working.
So I tried to empty the cache entering in the recovery but it was useless so the only way seems flashing the original FW with Odin. Downloaded the right one with Frija, upload the rights files in Odin (Home_csc because I don't want to lose my internal memory stuff) and the phone automatically reboots, pass the Samsung logo and go in Upgrading mode with the blue android screen and a % increasing. After that by himself power off and nothing happen.
I read some stuff about my possibilities to recover it without losing data but a lot of tutorial talk about entering in recovery but I cannot do it! Simply does not go in recovery with vol_up+bixby+pwr_button even after force shutdown it with vol_down+pwr_button or reattach the battery. The only thing I'm allowed to do is put it in Download Mode to be recognized by Odin.
I've tried to launch ADB devices but it is not visible in Download Mode.
I've tried to flash another firmware for the same model (theoretically my one is unbranded italian) but I tried with WIND one because in download mode there is a text "Carried_ID:WIND" but this FW Odin fail to upload it.
I've tried to flash the TWRP with Odin but fails on the phone with error "Custom binary(recovery) blocked by FRP Lock". I've searched how to unlock it but without have access to recovery or phone settings seems impossible. And this phone has also OEM Lock.
I've tried again to flash the FW but the only difference than before was the blue android robot with stucked text "Installing system update", "Erasing" , "yellow advice notice" and finally a green screen with "An error has occurred while updating the device software.Use the Emergency recovery function in the Smart Switch PC Software". And yes, I already tried with Smart Switch but the program does not detect the phone.
I've also tried to flash the original recovery but nothing change.
Seems that my devices is bricked or a kind of boot loop.
In my situation there is something that I can do to recover the internal memory data? I don't tried to flash the FW with CSC file because I don't want to erase all the data.
My Galaxy was original since the purchasing, no root or flashed a FW, only OTA updates.
I've attached a photo with the stuff that appear in Download mode.
