Galaxy Tab S SM-800 stuck with flashing TWRP logo

I was provided this device to try and help resolve the issue. I am not sure how it got to this point. I believe that it was rooted with a custom ROM, then the individual tried to install a stock ROM (method unknown).
The current situation is:
Galaxy Tab S 10.5 SM-T800 stuck in a bootloop with the TWRP logo on the screen. I can not get the tablet to go into download mode. I have tried all of the different methods to enter download mode, i.e. Power & Vol - & Home, Drain the battery > Plug into PC while holding Vol - & Home, Power & Vol + & Vol -. None of these combinations do anything. The only thing I can do to get a response is to press Power & Vol +, which reboots the device right back into the TWRP loop after the Samsung Logo. Power button alone does nothing.
The device is seen by Windows with the Samsung Drivers but is not mounted to a drive letter, and I can not mount it.
ADB , fastboot and Odin do not see the device.
I would like to flash a new rom either custom or stock, but I need to be able to get the device into download mode so it can be seen by odin.
Any help would be great.

Probably just timing and pilot error this one. I've never known of any Samsung device boot but be incapable of booting to download mode as download mode is bootloader related.
No working bootloader means dead device.
No matter what state the device is in at the moment with the usb cable removed, hold POWER + VOL DOWN (not up) + HOME until the Samsung boot logo comes up, hold for another couple of seconds then release. Download mode should appear.

I know it should be easy....
I know it should work but it is not, I will make a vid of the process and post. I can not make heads or tails.

Is the home button actually working, are you pressing it firm enough?
If the home button doesn't register then the tablet will simply reboot.
Its a bit odd why twrp doesn't fully boot though unless it's the wrong one.
Does it hang at the twrp logo or continually reboot?

help... my zenfone 2e (Z00D/ZE500CL) unable enter fastboot/droidboot, recovery

I'm not very familiar with phone terms but the situation is like this:-
- suspected like bricked
- connect USB to computer and press Volume Up + Power = USB Logo with white load bar
- disconnect USB and turn on = Repeatedly show Asus logo
- disconnect and press Volume Up + Power = USB Logo with red bar with a splash off Asus logo and turn off (a blink an eye)
- real problem is unable to enter droidboot/fastboot
I have tried to search for the thread to solve this problem but not successful yet. Method that I have tried so far:-
- installing iSocUSB
- installing Intel driver
- installing xfstk (FW+OS failed)
- installing MFT (not know which file that be used as zip/xml)
- run adb tools command (error: device not found)
- Intel SOC appear on device manager and when connect the phone to USB, it will appear CloverView too.
- installing asus pc link
- installing PDANet
I have seen most thread and discussion mention a phrase like "press volume up + power and you will enter fastboot/droidboot" but how about IF I can't enter fastboot/droidboot; they not mention the step. What should I do to enter it? I also search for key "Z00D(ZE500CL) unable to enter droidboot/fastboot" but result from google shows as what I mention before; the phrase "press volume up + power and you will enter fastboot/droidboot" which not working on me.
can anyone help to solve this problem?
please read detail... power button + volume up not working

you have to make xFSTK recognize the device properly.. install intel android usb driver as well along with intel soc. only way to enter fastboot is to install it temporary with xFSTK

I can't solve my problem I've tried any possible files. I made a right installation of the drivers disabling signature using win10. When I turn on my phone appears "Intel inside" and I need to shut down the phone, pressing and holding power button + vol up in order to make appear usb logo that stay there for just 1 sec and then it shutdown again. Connecting my phone to the pc in that second I can make detected it and the usb logo on the phone is still there. Pressing "Begin Download" the download start but it stops after the 5%, the bar under the usb logo on the phone became red, and the log tells me "Windriver Error: 0x20000015, timeout expired" after xfstk tried to send OSIP.
I don't know if the issue could be the wrong files, or drivers, or something on the GPflags. Any help? Thanks for reading

Need Help with ADB [Volum Up/Down + Power button BROKEN]

My ADB is On in settings and I can use ADB normal. But when my Phone is off I can't turn it on anymore the only way would be with ADB command: ADB reboot devices!
Power button + Volume UP/DOWN isn't working anymore...
The thing is, when connecting my Phone to my PC after it gets off it will show the charging animation. And when my phone reached 100% it stays in the animation and doesn't boot up. ADB isnt working in that state.
How can I boot my phone?? Pls I hope someone can help me PLS PLS

You must try conclude pins on motherboard for button volume up when you connecting USB cable, after that fastboot was started and you can type fastboot reboot command on pc.

If you have power and volume-down buttons functioning, boot the phone with the power button and when the bootloader unlocked warning comes up, press the volume-down button and you will get the options for restart, fastboot, recovery etc. Simply choose what you want with the volume-down button and confirm with the power button.

Question phone has bricked itself without seeing a solution

I do not know in depth about all this stuff, I've just been thrown into it because my phone decided to brick itself in a system update after it got into my hands. I updated it and it went into crash dump, a few times, the just nonstop boot looped with the oneplus logo on, and some pixels bugging, then it stopped showing the oneplus logo all together and just boot loops, I can go into fast boot and nothing else, if I restart bootloader it now goes to a charge menu and rarely actually restarts fast boot, I just tried msm and I've tried booting into twrp but it wont work, i believe this is because the phone wont connect to my pc properly but i have tried universal adb drivers, new sdk, and official QUALCOMM ones to all get the same result of appearing in device manager as just andrioud and nothing else with no options for drivers, on msm it would show up but it wouldn't get past waiting for device. also i cant find a proper twrp rom for the 9 pro on here, atleast the stock one, nor can i find it anywhere else, i can only find the img. also i feel I'm missing something with flashing on the fastboot and am not seeing if I'm supposed to be doing something (of the limited things i can do) on the phone, or its all in commands and stuff on here. sorry this is horribly written, I'm tired and stressed because of this.

Search stock rom and download
unzip rom ,connect your phone in download mode and flash STOCK ROM.

You shod download "EDL" tool (even called MSN)
unzip and exetute ad admin (read specifications and troubleshooting in the related thread)
ensure tour phone is off
press and keep both volume buttons while connecting it to PC
then the COM X connection should become "green + connected"
go with "start" and just wait the processo to end

Download mode is not vol up + power, that's bootloader
EDL (Download mode) is both vol buttons + power
It should show up in the device manager on the computer as a Qualcomm device if it's worked correctly.

EDL mode is NOT both Volume buttons + Power, it's just HOLDING BOTH THE VOLUME BUTTONS and WHILE HOLDING THE VOLUME BUTTONS, CONNECT THE USB CABLE. The phone needs to be in a switched OFF state before doing this.
By holding both volume buttons and the power button, you will force restart your phone into bootloader mode (fastboot mode).
And VOLUME UP + POWER BUTTON is recovery mode.

Question Need help unbricking -> EDL not accessible for MSM

[SOLVED see post below]
Hi all,
Just bricked my Phone and can't access MSM. Hope you can help me. I will try to be very clear on the steps I took to get to this point.
Device: EU OnePlus 9 Pro
What is was trying to do: Go from rooted C.47 to Pixel Entended ROM
What I did:
Code:
Unrooted using Magisk uninstall option
Updated to c.48 through OTA
Go to lineageOS page on how to ensure all firmware partitions are consistent
very stupidly did not flash dtbo and vendor boot partition
did adb reboot fastboot in stead of abd reboot bootloader
Download the "lineage-19.1-20220701-recovery-lemonadep.img" and tried to temporaryly flash it by
fastboot flash boot <recovery_filename>.img
This resulted in the device getting stuck on the 1+ boot logo.
I can still force turn it off by holding Volume Up + Power.
When I try to access EDL by turned off and Vol UP + Vol Down + Plug and release, My PC makes a connection sound and the screen stay black for a while. After +- 10 seconds, the PC makes a disconnection sound and the phone boots up and gets stuck again on the 1+ bootup icon.
Also my phone won't stay turned off when plugged in the charger or pc

Yes, but what is it presenting as (i.e. EDL, fastboot, ADB, UMS...) when it connects?
If this is Windows, UsbLog.exe is handy to identify things popping up (as long as they have drivers installed).
For a list of devices that have ever tried to connect, try "enumusb.exe /l".
Both available here: https://www.temblast.com/windows.htm

I will try this

I found the issue:
> EDL exits after 10 seconds if it is not captured by the MSM tool.
> The MSM tool only monitored 4 of my 10 USB ports
> So it was not captured because I was plugged in to an unmonitored USB port and rebooted after 10 seconds
> I have successfully used the MSM tool now

Oh! A bit off-topic, but I have never understood why EDL is commonly used over a "serial" port.
The interface that EDL presents is a generic USB bulk interface with two endpoints. You can use it just like that.
But no. They have to use a Qualcomm driver that makes it look like a "serial" port and then you can connect to that.
Me? I use a generic "WinUSB" Zadig driver. I have an EDL client that just connects to that fine.
So does the Python client implementation.
Also, I've never run into that 10 second timeout.

Your phone needs to be in OFF state mode when you're using EDL.
So, very simple:
Enter bootloader mode by holding both volume buttons with the power button together till your phone restarts and enters the bootloader.
From the bootloader screen you can use the volume buttons to navigate through the choices and you can select "Switch off".
When you complete this, you need to hold both volume buttons, and while holding them connect the cable (PC).
If you don't have or you don't have the correct Qualcomm EDL drivers installed, your phone will reboot or start to boot, it won't stay in EDL mode for longer than 10 seconds.
I also got the correct drivers for you, but you need to install the drivers manually while your device is in "EDL" mode, so, you need to be a bit "fast".
I have even a video for you, but need to upload it to YouTube so you can watch it.
I'll share you here the drivers just in case if you're familiar with a manual installation of the drivers.
