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?

Hey Guys
So my friend gave me a Note 2 with 4.1.1 that's stuck in safe mode.
So i tried installing TWRP to install a KitKat rom, but i forgot to format data "stupid me :\"
anyways at first it booted till the part where it's "optimizing apps"
after it got to "finishing boot" it rebooted and, well, it's stuck in a bootloop.
so i tried getting into recovery by pressing the 3 buttons, it just continues with booting into the bootloop.
then i tried getting in download mode, it gets to the warning screen, but it refuses to continue when i press the volume up button :|
any help?? thank you

perhaps try to reboot you phone by long press power button...
if you could get the phone to be recognized by adb then you could use:
adb reboot download​
to get to download mode.
Just a reminder:
TWRP :Vol Up + Home + Power (Release Power Button when samsung logo appears, keep holidn Vol Up + Home untill you see TWRP )
Download Mode: Vol Down + Home + Power, then press up when warning appears.
Hope this helps.

that was how i used to get the phone in download/recovery back when it was in safe mode.
but now, adb can recognize the phone, but it's "unauthorized" and stuck in a bootloop so i'm screwed :\
Anyways i think i should just take it to a repair shop but thanks so much for ur help guys ^^
If you have flashed a rom and your tablet "soft bricks", i.e. it gets stuck at the Samsung splash screen or boot loops Recovery there is an easy way to recover without having to reflash the original firmware in ODIN (assuming you were smart and made a NANDROID backup before flashing your rom).
TURNING THE DARNED THING OFF:
Here's the problem. If you are at the Samsung splash screen or boot looping Recovery, you cannot turn your tablet off by just pressing the power button and you can't pull the battery. This prevents you from getting back into Recovery and restoring your NANDROID backup. So here is what you do:
1) Plug your tablet into your computer (this is important!).
2) Hold down the home, volume down and power buttons until you boot into download mode. Once you are prompted, push the volume up button to enter download mode completely.
3) Now, once in download mode, hold down the power and volume down buttons (not the home button this time) until you screen goes blank (your tablet MUST be plugged into your computer for this to work!). Release the buttons and you will see the battery symbol on your screen. Your tablet is now off - thank god.
4) To enter Recovery mode, hold the home, volume up and power buttons down until Recovery loads.
5) Restore your NANDROID backup.
Disaster averted.

Only works if the tablet is off. The key part of this little tutorial is just turning the tablet off when you are stuck in a loop. Once you are off you're golden.
I panicked yesterday because i can't exit download mode with a simple hold of the power key,

Lots of new roms. Make sure you check those firmware numbers before flashing folks!
When I was stuck on the Samsung logo for 20 minutes after installing this (beta version) rom a week or so back I did this:
1. Held down the Home, Power, Volume up and down buttons for about 10 seconds, not sure if you need all of them held down, but it seems it force restarts the tablet.
2. After the screen went black I immediately held down the Home, Power, and Volume down buttons to enter into download mode.
3. Flashed the latest XAR stock rom from SamMobile.
If anyone is testing a new kernel keep an eye on those temps. An app called CPUTemp has excellent monitoring. You want to be staying under 100c even when benchmarking.
Almost there but
I did everything you said but when i press the recovery combo nothing happens.It is as if there is no recovery!!!
Help plz.I am furstrated and angry!!!

Ok that all worked fine, but now that I got it turned off I can't get it to go any further than the charging icon is there a way to push files to it while it off? any help or suggestions are greatly appreciated
Same here. Can get into download mode but can't get into recovery. I've TWRP.
Ok made it into recovery.
Update:
I've now wiped Cache and Dalvik Cache and after rebooting it now says Android is upgrading / Starting apps.
Is this a good or a bad sign?

Just downloaded and installed via Odin a firmware version of this tablet and all is well. Just have to start all over again, currently writing this due to a Samsung update for the firmware. YEA!

Thanks a lot. I just registered at xda developers in order to be able to reply and thank you. You saved my tabS 8.4 two weeks ago. However, I lost this thread since that time and I just found it again today after almost 2 hours of google searching. All that to show my appreciation for helping me to switch off my tablet having been stuck at the booting loop.
I would send you money if I knew how. THANK YOU SO MUCH! I had this problem with a Samsung Tab S I got at Costco, and returned it for a new one. That was about a year ago, and I was sure I would have to take it back again. You are uberawesome!
Kindly help me if u can ^_^

Dear,
My case problem is like yours, after I wipe from TWRP I do restart my device & I'm now stuck on Samsung Logo or Battery Logo (if I plug it with my computer).
Now how can I download a new firmware, although I can't open download mode or recovery mode through (Volume Down+Home+Power)?
Thnx n Adv.

You have a couple of options.
1) Do as the guide says. It usually works.
2) If it didn't work, unplug your device and wait until it discharges the battery and goes off. Then charge it from USB, and turn it on with holding down Home+VolumeDown+Power buttons until DOwnload mode appears. Then press VolumeUp, and flash it from ODIN.
Hello,
Can someone give me the EXACT procedure to enter into Download and Recovery mode please?
If my tab (SM-T830) is switched off, and I switch it on by pressing Vol down + Power and I keep pressing both buttons, it will boot until the first splash screen (Samsung Galaxy Tab S4 Powered by Android) then after this screen, it will reboot..
If I release buttons during this splash screen, it boots up normally
I already succeeded to enter to download or recovery modes before but I have no idea how. I guess I must release 1 or 2 button at the point but when ?
Thanks
Hello,
Hopefully this will be helpful, the following procedure worked for me:
make sure the tab is off
plug the USB cable in your tab (but not in your computer)
hold down both volume buttons together
plug the USB cable in your computer
then the tab start (you may release the buttons) with a menu allowing you to choose (Vol +/-) between download mode and reboot.

It works perfectly, thank! That's a weird way to go to DL mode but it works!
And once I'm already in DL (and flashed a tar with Odin), do you know how I can restart directly to Recovery mode without rebooting to system?

This is really late, but go to recovery and select download mode.
Power off
Hold down all three buttons (power, vol down, vol up)
Once it vibrates let go of power and vol down, continue to hold vol up. Never fails.

Did this several times exactly the same way it's described and it fails every single time. Other way worked perfectly and easily on my first try.
Hey all,
Hope you've been keeping safe and well.
So I was flashing the new PixelExperience ROM - and seems like I made an error somewhere along the way.
I'm looking to return to stock, and then give the process another shot - but at the moment my phone is stuck in a bootloop.
The bootloader is unlocked - and the boot goes through the following screens before rebooting:
1. Samsung Logo
2. "The phone's bootloader in unlocked....Press power key to continue"
3. Samsung Note 10+ Logo Screen.
I'm trying my best to try and boot into either download or recovery mode, but to no avail - it just restarts the bootloop on each combination I've tried.
Any solutions on how to get moving with this?
Thanks!

Timing will be the key. To help out, boot up as you have been, but as early into the boot cycle press and hold the Vol - and power button for up to 5 seconds (until phone manually shuts off) [it will actually reboot the phone])), then the instant it powers off and begins to power back on (try a few times to get used to the timing) press and hold the key combination for recovery or download mode. In my experience whatever combination you go with while booting, the power button only needs to be held for the first 5 seconds or so of the combo button press/hold.
The other button, Vol+ or Vol- should constantly be held until desired mode begins to load.

Thanks for your quick and detailed reply man, appreciate it.
Still trying, new cords, ports, the whole buffet. Will keep at it.
Major flag though - my PC doesn't recognise the phone anymore, checked the USB ports in Device Management and nothing comes up. I've tried different cords and ports to no avail.
I have a feeling that because the device doesn't think it's not plugged in - it doesn't boot into recovery.
Just another detail - the flash goes on just before the reboot. Does this signify anything?

I'm not familiar with any significance the flash may point to. You've probably already done this.....but be sure to reboot PC....
Have you tried booting to recovery yet?
I have TWRP and LineageOS with Magisk installed on my A50. Normally, when my phone boots, I get the following sequence:
1. Phone vibrates.
2. Samsung Logo appears for a very short time, with bootloader unlocked warning at the bottom.
3. A screen showing a bootloader unlock warning at the top and "PRESS POWER KEY TO CONTINUE" appears.
4. After a while or if you press the power key, an additional unofficial software warning appears in red letters at the bottom.
5. After some time the phone continues to boot normally.
My problem is that after the latest reboot ("reboot into recovery" via power menu), it gets stuck at step 4 and won't continue to boot, neither recovery nor system, even if I wait for tens of minutes.
What I've tried:
-reboot with volume +/-/poweroff
-reboot with volume volume -/poweroff
-all of the following with and without USB connected to PC:
-power/volume +/- at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume + at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume - at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-volume + at boot, both starting after logo screen as well as starting before logo screen
-volume - at boot, both starting after logo screen as well as starting before logo screen
-volume +/- at boot, both starting after logo screen as well as starting before logo screen
None of these helped. I just get the normal sequence 1-4 and then stuck every damn time. Can't get into recovery or download mode. Can't even power off, obviously.
Is my phone gone for good?
same **** here. for me i cant charge the battery too. but before that with about the same problems i got it to work again for a few days.
now hangs on step 4

With some help I managed to get into download mode, and from there reflash stock rom with ODIN.
Basically, you need to reboot the phone with power/vol+/vol- and as soon as the screen goes black, you release power but keep pressing the volume buttons, and also immediately connect the USB cable with the PC. Timing is key.

bro, you helped me alot, i'm stucked at this screen maybe 2 hours I didnt know what to do.
Btw, I've it just in 1 time =))
I got a way easier Method which has saved me several times
Is something i came up myself
Il be as precise as i can be so everyone understands!
1.Plug the phone to the wall (Your charger to the outlet)
2. Hold Power And Volume - (Volume down) until the phone shows the second charging animation (Which is the one after the first image of the phone charging [A circle with the lightning icon in the middle], this second screen shows a charging animation and the percentage of the battery) This indicates that the phone is fully Turned Off
3. Unplug your phone and the charger off the wall and bring it to your computer
4. Plug your cable to your Computer then back on your phone Hold Volume + and Volume - (Volume up and Volume Down) and plug your phone to your computer WHILE HOLDING BOTH VOLUME BUTTONS.
This little trick will put your phone in download mode so you can restore your device using Odin OR Flash Twrp with Odin and boot to right into Twrp (There is a way to do it without turning the phone on and having to go back to step 1, Follow this Tutorial to do it
(
)
I Hope this helps you all
And Happy Flashing!
