SM-N975U - Stuck in Safe mode - No Factory Reset Option Available - Samsung Galaxy Note 10+ Questions & Answers

Long story short, I have this Note 10+, No root, no custom OS.
I decided to use Package Disabler Pro to disable all the bloat, as well as the Factory Reset options and a few other things.
I did this because the phone was being used as a WIFI only tablet for my kids; I didn't need them accessing any options that might put them or the device into any harm.
Unbeknownst to me, this would send the phone into safe mode. Once in safe mode, the device stays powered on for maybe 12 seconds. The "You are in safe mode" banner appears across the top of the screen, and then reboots, back into safe mode...
USB debugging is turned on. But keeping adb connected to the device has been a challenge as it reboots so fast.
From recovery I cannot factory reset as the option to do so has been removed. I tried fixing all applications and i did nothing.
I was however able to remove the app through ADB, but it did not help. The device is still safe mode looping.
Something is preventing the device from starting normally.
Can I flash the stock OS to get the factory reset option back?
Through adb, when I try to force factory reset, it says cannot be found.

Verizon VK700 10.1

LG Pad Verizon 10.1 VK700
My tablet was stuck in upgrading firmware mode whenever I booted it up. Used LG tool to flash stock firmware, and it would hang at 28%.
Went into recovery mode and clicked wipe cache, and when I rebooted it now says
boot certification verify and the top left with the LG logo and it hangs here.
Can no longer enter download mode to reflash.
Recovery mode still works, but none of the options work
*Wipe cache (top of screen will say boot certification verify and hang)
*Restore factory defaults (will hang at Restoring Factory Settings)
*Safe mode (reboots to boot certification verify and LG logo)
Figured I could try to use SRK tools, but nothing comes up in my Device manager when I plug it in anymore (not even qhsusb_bulk)
When I power it off and on with usb plugged in, windows will occasionally make the new device detected sound, but then make the device disconnected sound about a second later, so nothing will appear in device manager.
Does anybody have any suggestions or any way I can get this thing running again? Or anyway I can get my computer to even recongnize it as qhsusb_bulk so I can use SRK tools?

Backup internal SD on phone that hangs on boot (at Verizon Screen)

I have a non-rooted VS986 (probably 26A).
Recently I ran out the battery and the phone died. When I charged it and turned it back on, it stayed stuck at the Verizon boot screen.
I hadn't really changed anything recently, and I did not take the most recent OTA (27C) so this just seems like a random hardware failure.
I can boot into Recovery, but if I choose "Safe Mode" or "USB Debug Mode" the phone just hangs at the Verizon Screen.
I tried to Wipe Cache and restart, but it just hangs at the Verizon screen.
I *can* boot into Download mode.
I would really like to back up the internal SD card--photos, settings etc. if possible.
Is there anything I can do at this point just to get an ADB prompt or something that might allow me to perform a backup (even if limited)?
Sounds like a motherboard failure. You could try booting into download mode and using adb to pull your files but you'll have to know the exact path to their location. And to do that you would have had to have USB debugging activated.
If that doesn't work then your SOL. Time to use your insurance or warranty if it's still good.

T-Mobile S8+ [G955U] -- Factory reset resulted in complete wipe & no longer boots up.

T-Mobile S8+ [G955U] -- Factory reset resulted in complete wipe & no longer boots up.
I have a Samsung galaxy S8 plus (T-Mobile) [SM-G955U]
Current Firmware:
G955USQU4CRE9
I'm using windows 7 to attempt to repair my phone.
My problem is as follows...
A few weeks ago my phone started giving me the dreaded:
"Unauthorized actions have been detected..."
error code and sending my phone to restart.
This has happened to me in the past on other phones so i thought, ok. restart and it should be fine. However, this kept happening... the next day and on the 3rd day it happened about 3 times in a row. At this point I was cautious and backed up all my files, turned on USB debugging and shut off my wifi & data.
I then proceeded to do a factory reset from the settings. Once it restarted I got a weird error stating something like no such recovery file could be found. When I saw this I knew I messed up because I didn't first take a backup of my system & recovery...
I got a hold of T-Mobile who walked me through their reset steps, none of which worked. They had me contact Samsung and I did but to no avail. Simply stated they mentioned they could fix it if I had warranty, if not I would have to pay for repair.
Either way I sent all information to Samsung and they have not gotten back to me even though they mentioned we'd hear back in 48 hours. (it's been about a week) I've tried to reach out since then but I haven't had a lot of time to sit on the phone with their elevator music...
Ever since then I've tried everything from Samsung Smart Switch to re-flashing through Odin with no luck.
I've tried all of the reset options...
Hard reset
Soft reset
Wipe cache (recovery mode)
Wipe and factory reset (recovery mode)
Simulated battery pull
etc., etc., etc.
Nothing works. Odin flashes correctly (i get "PASS") and the phone turns off but does not turn back on.
I've tried several tricks to get it to turn back on but it won't go past the boot screen (Samsung Galaxy S8+ screen)
I've flashed, re-flashed, wiped, reset, etc.
Now smartswitch doesn't even work on it because it does not recognize the device...
When i connect my phone now it just shows up as the qualcomm chip. I get "Qualcomm HS-USB QDLoader 9008" under devices...
ADB only works when it's in download mode or recovery mode but it doesn't recognize the device either...
Another problem is the increased time it takes to get into the boot menus (download or recovery).
Sometimes when I haven't touched my phone for a whole day I can get into download mode within 10 seconds or less but the more I try it and especially if I successfully flash stock software, the next time booting into recovery or download mode can take up to 5 minutes (holding the button combination). Recovery mode is worse.. even after 24 hours without touching the phone it will come up maybe in 3 minutes but has taken as long as 7 minutes... my fingers are in pain.
Essentially, even after successfully flashing my phone will not boot. and when i hold vol_down + power i can sometimes get the boot screen but it won't go past that.
Also, None of the above boot options work if my phone isn't connected to power--these options only work when it's plugged in. If my phone is not plugged in it will not vibrate, light up, boot up, or do anything other than behave as a paperweight.
I believed it may have been a charging issue so i left it plugged in overnight and even went to download mode and plugged it in for a few hours but that doesn't affect it at all. Even if i'm in download or recovery mode it'll turn off right when i unplug the device.
I'm trying to get it to the best buy that's approved for samsung repair but when I called they said they wouldn't repair it anyways because i didn't buy it there... -_-
Please let me know if I need to provide any other information. I'm trying to get an image of the recovery screen so you can see the error it gives me... Something about no file found. This is increasingly difficult though because some times it takes too long to get into these modes and I leave it alone and come back to it later.
Has this happened to anyone else? Can someone provide some sort of advice or a method to fix this?
thanks in advance.
Can you download the Qualcomm HS-USB QDLoader 9008 driver, and then see if you can fastboot oem-unlock and see if it unlocks your bootloader

SM-T835 restart endless boot loop

Last night i restarted my tablet, but continually drops into recovery mode.
I have also been in a menu which recommends 'erase app data' to boot into safe mode, in order to backup data, prior to factory reset. So i have erased app data, but now just enters recovery menu.
I'm not sure i have any debug/developer settings switched on this device, as only flashed roms on phones long time in the past, not this tablet.
So can anyone guide me to get it into safe mode to take copy of user data partitions?
Have dabbled with some adb but doesnt recognise any devices, so wondering if being blocked by some security.
Thanks in advance

Phone powered off wont reboot

My 5T decided to power off in my pocket this eve. Tried to reboot and now it won't accept my pin. Tried to boot into recovery mode (power & volume down) but only comes up with keyboard, not menu. Tried rebooting using power & volume up to get recovery mode but again comes up with keyboard. Option of forgot password gives factory reset which i want to avoid if possible. Any help please? Thank you
There are multiple ways to bypass a screen lock.
First one is using an adb command, just search on Google "how to bypass android phone with adb" and you'll find it, but for this your phone needs to have USB debugging enabled but it's already locked so it may be useless. This method will work without losing your data.
Other is using a specialised software like "DroidKit" or "DrFone by wondershare", this method will be frustrating because the software may push you to buy a subscription or something but it'll alsol work without losing your data.
