MDM Locked Galaxy Tab A - Samsung Galaxy Tab A series Questions & Answers

I have a Samsung Galaxy Tab A (2020, SN-T307U) that I got from work. It's an old Doordash tablet that Doordash didn't want back, so I'm trying to reset it and it's driving me crazy. I have followed so many tutorials trying to get this thing to work, I keep getting caught on something.
- Simply factory resetting does not work, gives an error that MDM does not allow it.
- I cannot put in the wrong password 15 times to factory reset, even though I get a warning it just lets me continue trying after 15 fails.
- I cannot enter the bootloader, rebooting to bootloader just reboots to the OS.
- I cannot enter safemode, same as above.
- I cannot enable developer options, so no OEM unlock or USB debugging. Tapping build number gives me an error that the MDM does not allow this option.
The device is recognized by Odin, can I just brick this thing and repartition from scratch? Can someone who knows what they're talking about walk me through that? I'm not really sure what I'm doing here, learning as I go over these last 2 days.

Hello,
I have the same exact same issue, have you been able to unlock it?
Thank you!

I can fix it remotely the last hope

Same Issue here,

Any one had any luck with MDM T307U. Please assist.

If you look at all of the previous post, it should tell you that no one has found a way to disable an MDM lock. Which is as it should be. Otherwise the lock would be useless.

That's not true as of today's date. (In the event this post is viewed after this exploit can be successful).
I am not taking credit and perhaps the op has discovered it. Anyway...
I am in Canada and noticed the carriers here stop at BL 8 while the USA has BL 9.
The unit i had was on BL 9 (csc TMB).
This probably works for Canadians on BL 8. I don't recommend flashing to BL 9 as that may affect your service or experience.
ANYWAY! This guide won't explain any prerequisites. They are adb, installing unsigned drivers, and you aren't able to use the device and are the owner
1) if not already, power off device with vol down+power and ensure battery is at least 50%.
2) enter recovery and factory reset. If you're having difficulty entering recovery, plug into your pc and as soon as you hear the audible disconnect, switch to vol up+power. Or jam on all three buttons for dl mode.
If in dl mode you can check firmware version and just flash it with bl, ap, cp and csc (NOT home csc). Use exact current version. Don't worry about userdata if it is USA
3) at welcome, connect wifi and imnediately go back to first screen. Don't use data sim
4) dl samfw app and on misc tab, check driver status and your pc will reboot.
*you must not have secure boot enabled
5) plug phone into pc. In the app, mtp and select youtube. If done right, click the pop up on your phone and navigate to chrome. Should be automatic.
6) search for vnrom frp. Once there download package disabler pro and notification app. They are side by side. Install notification app and set it up so you can swipe quick settings from top of screen.
5) unplug your phone from pc and plug it back in. Should be able to get back to the package app various ways to install it. Before install, turn wifi off. Now run package disabler and when it prompts for device admin, turn wifi on. It'll glitch a bit but should start.
6) locate samsung setup wizard. Don't confuse with the other. It'll have a green icon. Disable it and clear the storage. At bottom left, tap the back arrow and you should be back at final setup.
7) when asked to add samsung account, turn off wifi. Complete setup and don't add any accounts.
8) you should arrive at home screen. Your phone is re-plugged right? Good. Now turn on usb debugging and use the remove knox from the app. Done.
*i think i turned wifi on just before enabling debugging. I forget.
*if you are sloppy... you'll need to start over. You'll see, or already know
*you can do ota (if there still is any) but factory resetting or odin flashing will put you back to managed.

This method works up to step 7 for me. I can't seem to enable usb debugging before knox kicks in. With or without wifi. I'm experimenting to see if I can get past that step.

How to Remove MDM Control from Android?​For anyone suffering from this issue, the following are the steps to bypass Samsung Knox factory reset protection:
First of all, create a password for the device.
Make sure that your device is charged to an 80% or greater charge.
Next, you’ll need to go to Settings and Security Encrypt Device tabs respectively.
Set a PIN/password for your device.
After you have secured your device and it’s gone through. Reboot the device, and when it boots, it will ask you to enter a password in order to access your device to view encrypted data. If you type the wrong password 15-20 times (it depends on your device), it’ll wipe your device of any information and will restart and then appear like you’re registering as a brand new device after a factory reset.

Thats the 2th!!! Try it

bricked galaxy s7 edge

I rooted my galaxy s7 edge (snapdragon) and everything was fine and working except I couldn't get SuperSU to install properly. I would get the app screen, but nothing else. A couple of apps would show up (Root Checker, Flashfire) after I had run them but I didn't get the typical SU screen with settings. I'm not including the softwares used (I did have debugging enabled in Develper options on the phone, secure boot unchecked, and the correct Samsung USB drivers installed) because I don't think it's relevant to my question - if not so, let me know and i'll be glad to provide the info - I'm a newbie at this so please bear with me). I read about the warning to not update the 2.74 version of SuperSU but then I saw the update beta for 2.77 so I tried that. It appeared to run ok; I could see all the commands being executed and then ending and then the phone rebooted, as it's suppose to do. This is when the problem emerged; a screen came up saying "start up failed" and at the top left of the screen it said 'Custom binary blocked by secure boot (boot.img). I rebooted to TWRP recovery mode and tried rebooting which again resulted in the start up failure screen. I then tried the wipe data\factory reset setting and the same thing happened. I then booted to maintenance mode and got the warning screen about a custom OS installation can cause problems but if you want to proceed press volume up key which I did and got the usual Downloading page. At the top of the Downloading page I noted it said, among other identifying info: Odin mode (high speed), FRP lock: off, QUALCOMM Secure Boot: enable, and Secure Download: enable.
But, when connecting the usb cable to the phone and pc, my computer (Win 10) doesn't even see it. Not sees and doesn't recognize, but doesn't even see it. I tried a second USB cable and different ports but got the same results. I tried a second computer and got the same thing.
I am guessing that if I could still access the phone to run rooting apps I could get past the lock. If not now, maybe later on when someone figures our a way to do so. But without a working connection to the phone I am helpless. I am wondering if Verizon disables USB intentionally, so that the phone essentially becomes useless. Or, is it a coincidence and perhaps there is something wrong with the usb hardware.
Is there a way out of this other than having to pay for it to be fixed (which Samsung won't do - I called - and maybe Verizon not either).
Thanks in advance -

Verizon Note 3 - please help me flash custom ROM

I have a Verizon Note 3 running Android 5.0, non-rooted (never had luck getting it rooted). As far as I know, the bootloader is locked. Here is all the information that I thought might be pertinent:
Model #: SM-N900V
Baseband version: N900VVRUEOF1
Android version: 5.0
Kernel version: 3.4.0
Build number: LRX21V.N900VVRUEOF1
Although I work in IT and am fairly comfortable with this sort of stuff, I have almost no experience when it comes to working with Android development / phones, etc.
The phone does not have a valid SIM card, nor do I have service for it. I use it just as a WiFi device and I don't care if it ever works for phone/SMS/MMS again. That being said, I would really like to be able to (a) root the phone and (b) load the Resurrection firmware that I've read about that would allow me to run Marshmallow.
Is there someone who is willing to take me "under their wing," so to speak, and take me through what I need to do, step by step, to make this happen. I've read several posts, but they all assume a prior level of knowledge that I just don't possess. I'm confident that I could do this if I have a clear list of instructions and and understanding of what steps I need to follow to do this. Thanks in advance to anyone who could give me a hand.
Same problem here. Would appreciate help
Alright,
*First thing you need to do is enable USB debugging:
How?
On your phone Navigate to Settings > About Phone > scroll to the bottom > tap Build number seven (7) times. You'll get a short pop-up in the lower area of your display saying that you're now a developer. Then Go back (to the settings menu) and now access the Developer options menu, check ‘USB debugging’ and click OK on the prompt.
------------------------------------
(DONT plug your phone to your PC yet)
Download USB Drivers and Install.
------------------------------------
*2nd thing to do is Rooting your phone:
Download THIS tool on PC > Run. then plug your phone to PC > Choose Version OF1 > Click Read phone info (Your phone will ask if the program can access your phone press YES on your phone)> Root. wait until its done. now you are Rooted.
------------------------------------
Here is the fun part (Unlocking your bootloader) All through the phone no PC required for this.
You need to use an SDCard for this and
Keep in mind this method ((WILL WIPE YOUR EXTERNAL SD CARD)) So backup your MicroSD or use another one.
* Install Busybox on your phone (you can get it from the Playstore)
* Download Samsung Unlocker N3
1. Install SamsungUnlockerN3.apk
2. Grant SU access
3. Click On Install SamBootloader Unlocker
4. Grant SU access
5. Type Yes Hit enter wait for device to power off. Then pull the battery out > Battery back in then power on the phone.
6. Should be unlocked
Keep in mind this method ((WILL WIPE YOUR EXTERNAL SD CARD))
Thats all. your N3 is rooted and bootloader unlocked

Try to do a factory reset in recovery mode. It will wipe all your apps and data and restore it to factory settings. The instructions you got from @Sczar are very good , so try again step by step if factor reset doesn't work to get you out of the boot loop.

OK, made it to rooted. It came back up the first time while connected to the computer. I shut down to swap sd cards to put in an older one that isnt used and when I start back up all I get is Process System isnt responding in a white box. If I do nothing, the white square asking to quit or wait will disappear, I get the top bar with 4G, bars, battery level, and time, but black screen. If I swipe the screen with my finger, the desktop (for lack of better word) flashes on, then goes all black. In about 3-5 minutes it will restart again. Before it restarts on its own, I can hold the power button and it will give me the power off, restart, etc menu and allow restart.
EDIT: Nevermind... If it warns Process System is not responding, wait for the notification bar to appear, use the power button to get the restart menu and choose restart. Then it starts normally and is Rooted! THANK YOU! I will work on the rest tomorrow!

It just started, I assume, as a result of running the root program. I downloaded program from the suggested link. I ran it which installed files on my pc and made a desktop shortcut. I double-clicked the shortcut, the program started, I connected the phone via usb, and selected the scan button in the program. It found the phone and I selected install root. I then had a progress bar start in the program and a window opened on the task showing odin 3.10. The phone indicated that odin had started and said it was downloading, however, progress stopped at 28 seconds. Did I do something wrong? I would really like to get this thing rooted so I have control over it.
Thanks immensely for your help.

Yes on both accounts. Because I had no intent to flash a new ROM and only wanted to root I did not have an SD card in the phone. Could this be affecting the process?

If you just want to root your phone you only need to run the root program on your pc. You DO NOT use odin. If I'm reading your post correctly you are saying the odin program is starting automatically? That should not happen. SD card should not matter if you just root.
Yes it is starting automatically. Any ideas why. Going to search registry on computer to see if it might be on there. Does Samsung Kies use Odin in any manner. I do have Kies on the computer. Grasping at straws I know. Thanks for the help you folks are great.

I have no idea why odin would start on its own. If you would like to, uninstall Odin so you can root your phone without any interference from Odin. Samsung Kies DOES NOT use Odin. Samsung Kies is its own separate program from Odin.
If all you want to do is root the phone follow Sczar post and run the root program again it should only take about 1 minute tops to root phone.
Tried one more time. Stopped in exactly the same place as multiple times before. As far as Odin goes; after downloading the root file and running it, it extracted a number of files and created a directory in my program files directory on my pc. One of the files extracted was Odin.exe. Also the program does not automatically detect my phone or ask me to select OF1. I have to select a scan button and it then populates the fields showing the build. I select install root and all goes good,like I have mentioned until 26 or 27 seconds of progress has occurred the the program stops. My phone shows Odin has started and says it is downloading not to turn off, but nothing ever writes to the phone. I have to get into the task manager on the pc to stop the processes dealing with the root program as it becomes totally unresponsive. I have to kill adb also. I am totally baffled and about ready to give up. Wish I had stayed with Motorola at least that phone I was able to root. I have been holding off the new software update for days but may just let it fly unless someone has any other ideas about why this thing stops. Thanks to those who have tried so far.

I'm starting to figure out what you are saying is going on (I think).
1. Forget about Odin you do not use it, at all for root.
2. If I'm right your "phone" is going into DOWNLOAD MODE automatically that is what it should do.That is not Odin running. That's how your phone programs itself.
Quick checks
1.Make sure you have latest drivers from Samsung installed.
2. check USB debugging is on.
3. Install Arabic Tool For rooting on PC.
http://www.mediafire.com/?pvm1reerboz2c25
4. Open Arabic tool,
5. plug phone into PC make sure you connect as MTP not installer mode.
6. Click on Version, select OF1 (make sure your firmware is running on OF1)
7. Click Read Phone Info. (Your phone info should fill in the blanks)
8. HIT ROOT.
Your phone should go into "Download Mode" not Odin (a little green dude should be on the screen) automatically. Let the program do its thing. Then it will reboot your phone automatically, and if everything goes correctly it should say your rooted!.
9. It should take about 1 or 2 minutes to complete.
10. If it doesn't work try it again. It took me 2 tries for it to work right.
Everytime I've tried rooting my SM N900V with this Yemen tool I get hard bricked. To fix that issue I just put phone in odin mode and flash the OF1 firmware and everything is back to normal but still no root. Any suggestions?

Try the Arabic tool I posted above ^^^. I rooted my phone 3 times with no problems. I've not used the Yemen root method.
I made it to root, but the bootloader is not replacing so I am evidently missing an obvious step.
Samsung Note 3 SM-N900V 0F1 firmware
1. Install SamsungUnlockerN3.apk
2. Grant SU access (How do I do this? It is not asking anything)
3. Click On Install SamBootloader Unlocker
4. Grant SU access (Again, how do I do this? It is not asking anything)

6. Should be unlocked
It says it works, it shuts down and I remove the battery, and I reboot. However, as soon as I install TWRP and allow it to reboot I get the unauthorized software message from Verizon, use Kies to save, use Odin to reflash 0F1, root again, and now what? Why is the actual bootloader not being installed? How do I enable superuser?

My experience with FRP lock and how I solved it...

So my nephew brings me his galaxy s6 t-mobile phone... He forgot his lock pin so he factory reset it. Now he can no longer get into the phone because he doesnt know the correct email or password. I did some digging through the net watched a few videos... and found none of the methods they used to bypass the lock would work on his phone. Then I read about the Combination Rom (Factory Binary)... At this time I do not have any windows pc's and my VM will not read the usbs of the phone... (im not that experienced with vm to set this up) So i grabbed JOdin for linux and proceeded to try to flash the binary. However, JOdin did not work for me. So i found Heimdall and installed to learn that i had to find some weird way to run it as SU for it to work... Tho Heimdall worked like a charm.... With Heimdall I had to take the rom and completely extract it to a folder and find all the img files in it to install on heimdal like sboot, boot, cm, system, and quite a few others as well.I used the "PIT" file from the combination rom (which came in the download). When done installing the phone boots into Factory Binary... Interesting little rom... From here you can access settings, tho the instructions tell you to enable developer options and turn on usb debugging... in this rom they are set on by default i believe, so that was kind of a waste of time... then from the main menu you click the icon that looks like a calculator and type in "*#0808# where you are then presented with usb options. Select the last one on the list with adb at the end of it, click save and reboot. At this point I thought i was supposed to install the stock rom back (that was where i was lost) however all you have to do is let it boot back to binary. After it has reloaded... plug it into the pc and send it the proper adb instructions to disable frp lock. Techeligible has a batch file for use in windows, however if you dont have windows like me that does no good... So I went into the batch file with a text reader and extracted the information i needed ( 3 adb commands).In terminal i made sure my adb and fastboot were updated and working. I learned that when you type "adb devices" it will show the phone and if it says nothing else you are good to go. However it may give you a problem with permissions. If this is the case then unplug and make sure usb debuggin is on, you can also check that the adb is enabled again by doing the *#0808# command again and make sure the last selection is checked. When all is in order... At first I thought all commands must work for it to succeed... However this is not true at all. Only one of the adb commands will not give an error and at that time you can reboot into download mode and install the stock rom back on. After installation the phone will reboot and FRP Lock is no longer on... Now you can go into settings open up developer settings (tap build number till it unlocks) and select "OEM Unlock" and turn it on. Make sure usb debugging is on and you can boot back into download mode and install TWRP without a hitch.
I tried installing a couple of custom roms, however I have had no success with getting one to boot. (always stuck in boot loop even with wipe or factory reset) so I gave up and left him with the stock rom. If anyone has any idea of how i could get passed the bootloop maybe i can try again for him sometime and see how he likes various custom roms, but now he is happy he has his phone back working and it only took me a week of off and on frustration to figure it out... Hope this helps someone... (please dont ask for links) but if you do need help or have questions feel free to ask.

How I Rooted Walmart Onn Tablets (No TWRP Needed)

I'll be making a video for this with the 7 inch tablet on Nov. 29th or 30th (depending on the time I have)
General Disclaimer: I'm not responsible if you brick your tablet. This is how I did it personally as other methods here didn't work for me. I have yet to test this method on a 7 inch, also do not have access to the Surf variants. This has only been tested on the 10.1 inch with the keyboard. Will update when I test with the 7 inch.
What's Needed:
MTK Fastboot Drivers: https://online.mediatek.com/Public Documents/MTK_Android_USB_Driver.zip
Magisk Manager Canary: https://forum.xda-developers.com/apps/magisk/dev-magisk-canary-channel-bleeding-edge-t3839337
Stock Boot Image: https://forum.xda-developers.com/wa...eral/stock-stock-backups-images-otas-t3998227
ADB and Fastboot: https://www.xda-developers.com/what-is-adb/
Prerequisites:
Personally, I had issues getting my PC to recognize the tablets in Fastboot mode. The drivers wouldn't install. This might be optional for some of you, but I thought I'd include it just in case.
Installing MTK Fastboot Drivers from the link above
If you plugin your device in fastboot mode and your PC doesn't recognize it, follow these steps. If it did, skip this part.
1.) Download the drivers above and unzip the Zip file somewhere on your PC (desktop or My Documents is easiest)
2.) Boot your Tablet into Fastboot Mode by holding Vol + and Power, then select Fastboot from the Menu
*NOTE* There is a bug with these tablet's that the volume buttons are mislabeled. Really dumb, but I guess that's why they were 55 bucks for the 10 inch on black friday
3.) Plug the device into your PC and open Device Manager by pressing WinKey+R and typing devmgmt.msc, hit Enter
4.) If there's an Other Device listed called Android, follow these steps. If it isn't there, follow the next set of steps
5.) Open a Command Prompt window as Admin and type the following command
Code:
bcdedit.exe /set nointegritychecks on
6.) Hit enter, then restart your PC
7.) Once the PC is restarted, make sure your tablet is connected in Fastboot mode and open Device Manager again
8.) Right click Android under Other Devices and select Update Drivers
9.) Click the Browse my Computer for driver software button and select the MTK Folder you extracted from the download link above
10.) From there, you can open command prompt, type fastboot devices and see if your tablet shows up and move on to root!
Unlocking your Bootloader
From here, you can unlock your bootloader very easily to Root your device
This will wipe all data off the tablet!
0.) Enable OEM Unlock and USB Debugging on the tablet by going to Settings->About and tap Build Number 7 times. From here, enter the new Developer Options that unlock and turn on OEM Unlock and USB Debugging.
1.) Boot your tablet into Fastboot mode and connect it to your PC
2.) Open a Command Prompt window and type the following command, then hit enter
Code:
fastboot flashing unlock
3.) Follow the instructions on screen to unlock your bootloader
4.) Now Boot your device and we'll move on to making a rooted Boot Image
Creating a Rooted Boot Image with Magisk Manager
0.) Make sure you already have Wifi setup and connected before the first time you open Magisk Manager on your device! Make sure it auto connects as well
1.) Download Magisk Manager Canary from the link above
2.) Install it to your device
3.) Download boot Image from the Stock Boot Image part of the Prerequisites above and put the boot.img on your devices internal memory
4.) Open Magisk Manager and select Install Magisk
5.) Select Patch File and select the boot.img from your internal storage
6.) Once its done patching the image, take magisk_patched.img from the downloads folder of your device and move it onto your PC
7.) Boot your tablet into Fastboot mode and plug it into your PC
8.) Open Command Prompt and type the following command and hit enter (make sure you know your magisk_patched.img file location)
Code:
fastboot flash boot magisk_patched.img
9.) Reboot the device and you'll be Rooted!
Optional Steps like Modules and Debloating
My basic debloat script: https://forum.xda-developers.com/wa...s-general/root-walmart-bloat-remover-t4011639
Will be testing GSI roms on the spare 7 inch and will list those here
Recommended Magisk Modules:
Viper4Android Legacy
FDE.AI
MagiskHide Props Config
Systemless Hosts
Youtube Vanced Black
Magisk Setting to Enable:
Magisk Hide
Rename Magisk Manager App (keeps app from detecting magisk root)
Credits:
Myself for this root method @byproxy for reminding me to add the steps for OEM Unlock and enabling wifi before opening Magisk Manager for the first time
I'll start this off saying i'm an amateur at this, but I cannot for the life of me get an option to show up in magisk to patch the boot image even though it's on my 7" tablet. Any thoughts?
The bootloader was unlocked and it was successful so that's not the issue.
Are you online? I had the same problem.

Sorry, been a busy few days, but make sure you're connected to Wifi, close Magisk Manager, then reopen it and you'll be good to go!

I purchased the 8" Onn walmart tablet second hand from a store called dirt cheap. Box didnt look to be opened but it had been. The tablet had been setup with someones gmail account that i do not know. The tablet was for a 4yo girl to use to learn preschool. Is there just any simple way to remove this google FRP lock ? I dont care if i lose the info on it as its not mine. I just want her to be able to use the tablet. Any help would be much appreciated please

Forced factory reset should do it. There is small pin hole near the power button. I believe pressing this hidden button(with a Sim card ejector, or paper clip).
If pressing does not do anything. Maybe press the button then hold power button too

Thank you for responding so fast. I've boot into recovery mode /wiped everything...its back to factory. The pinhole reset button does nothing other than reboot it . Ive tried all combos to with the reset button but nothing. Also i've read that its possible to use odin? if i can get it into download mode.
Ive downloaded the stock rom posted on an sdcard wondering if i can possibly update in recovery mode? Im sorta a newb at this stuff. I've been reading for 4 days on this matter. I've practiced a root on an old tablet with success. I guess at this point unless i can sell it as is giving the customer that it has this frp lock on it. If the know how to fix it so be it. Im not sure there is a working solution for frp bypass on these tablets.

This is an mtk device not Samsung. So there is no Odin or download mode. There is spflash tool, and preloader.
And if you flash firmware (with default frp partition) then frp lock is cleared.
But you will have to find that file. It maybe in the stock firmwares that are shared, I do not know.
EDIT:
i was having issues but figure it out. maybe it should be so common knowledge that it shouldn't need to be included as a step, but since i don't do this THAT often i didn't think about it and it took me a bit to figure out why i was having issues.
once you get your computer to recognize your device (mine did without needing to mess with any drivers) you need to first make sure to got into the tablet settings -> about and then tap on the build number 7 times to access developer options. then you need to go into developer options and turn on OEM Unlocking & USB Debugging.
THEN follow the guide to unlock bootloader.
then (since the tablet is factory reset once you unlock) do the above AGAIN to turn USB Debugging back on after you reboot.
also note that you need to have an internet connection on the tablet to utilize magisk. once you got all that square, then continue on with steps for full root.
hope that helps!

I did not realize I didn't include that step. Total noob mistake when typing a tutorial up for android. I do this almost daily at work, so I forget to include it

I was able to remove FRP lock on one of mine by flashing the stock rom with SP Flash Tool. I used the full wipe and download selection with every partition selected including boot.
no worries! i didn't think about it either until i was having issues. thanks for the tutorial... it was super helpful!! btw it definitely works on the 8" tablet.
Hello! I'm new to all of this, but what I'm trying to accomplish is removing the Google account from this tablet and putting a new image on the ONA19TB002, ONA19TB003, ONA19TB007, Surf 7 and 10 tablets. I followed all of the steps as far as installing the drivers. I had to go through hoops to get the MediaTek Drivers installed, but I have a "warning" cone by it. I haven't been able to find any resolution to this. Any help would be appreciated. I' have a Windows 10 64-bit system that I'm using and the tablet I'm specifically working on at the moment is the ONN ONA19TB003 tablet. The tablet is not being recognized by my laptop when I run the 'fastboot devices' command in PowerShell. Is there something that I'm missing? Any help would be appreciated.

Personally, I avoid PowerShell at all costs. This kinda stuff has always just seemed to work better with CMD.exe instead of Powershell.
These tablets are kind of a nightmare for this. If you've done the mediatek drivers and still have the warning cone icon, I'm not sure what's next as I haven't hit that wall myself. All I can maybe recommend is right click delete drivers in Device Manager, then start over with the driver install
Removing the Google Account would be needing a FRP Bypass. Someone above stated "I was able to remove FRP lock on one of mine by flashing the stock rom with SP Flash Tool. I used the full wipe and download selection with every partition selected including boot. " so if you can get it recognized, try that

Ok, thank you! This is a shot in the dark, but in order for ADB to work, USB debugging has to be enabled. I can't do that as the tablet is locked by FRP and I have looked countless times on Google and MSN to see if it's possible. Do you have any tips for that?
I don't know what I'm doing wrong, but for some reason I can't seem to get. The tablet to stay in fastboot mode. It just says waiting for device.

Sorry for late reply. Been away from home with work. When fastboot mode indicates "waiting for device," it generally means that your device is not properly communicating with your PC or laptop. This is nearly always due to missing or incorrect drivers 9n your computer. There are several comprehensive guides here on XDA for installing necessary ADB & Fastboot drivers.

S10+ recovery using DroidKit

I succeeded in locking myself out of my phone. With no other option (no Google/Samsung accounts, no developer mode, etc), I am looking at using DroidKit.
The problem there is that they took my money very quickly, but I can't get any tech support response from them.
As I understand it, the point is to write as little as possible before recovery.
In theory, files can be unerased in the same way that they can in a Windows OS.
The question is this: The phone was shut down after being wiped. When I start it next, it will want to do a setup, but I'm afraid that process will overwrite data.
Should I leave it at the first screen and connect it with a cable ? Can the phone be reached on a clean start without specifically turning on developer mode ?
Should I go through the setup and then enable developer mode ?
Are there other steps I should take in order to avoid overwriting ?
