SM-T810 stuck in boot loop, unable to enter in recovery or fast boot - Galaxy Tab S2 Q&A, Help & Troubleshooting

After I tried to backup the device with TWRM, I am now stuck on the boot screen with "samsung galaxy tab s2, powered by android" screen.
I am unable to do anything: turn it off, power + volume up + home or power + volume down + home" nothing actually do anything.
The only think that change something is it to wait battery run out of energy, then the screen turn black but as soon as I plug the charger the same screen "samsung galaxy tab s2, powered by android" come again, I didn't even pushed the power button.
The device was rooted long time ago and was still with the original rom (5.0.1 or 5.1.1 I believe, i am unable to verify).
Any help is welcome!

bump,
I tried removing the back cover, now I can reboot the device more easily just removing the battery connector, before I had to wait the battery run out of power.
I trying the boot the device with the "volume up + home + power botton" pressed.
But still no luck.
Is there a way to boot an alternate rom on the device ?

it turn out that removing the back panel actually disable power or volumes buttons, so putting back the backpanel let the "power + volume down" reboot works, then shortly after doing "volume up + power + home" button let me enter odin mode, now I need a stock rom...

Bootanimation loop

Hello everyone.
I got a new Galaxy Ace S5830i today.
I rooted it and installed CWM (http://forum.xda-developers.com/showthread.php?t=1552792).
After that I did install Retribution beta 4 (http://forum.xda-developers.com/showthread.php?t=1806471).
Then after rebooting I ended up getting a boot animation loop and neither the recovery mode would work nor the download mode.
Could anyone of you please help me? I feel very uncomfortable with a brick in my pocket. :x
I'd be surprised if neither were working, particularly if you are getting as far as the boot animation.
To clarify, to enter recovery mode: Switch off your phone (pull out the battery and re-insert if its looping and the power button won't work), hold down power button AND home/rectangular button AND volume up button. When you see the Samsumg GT-S5830i logo, let go of the power button but continue to hold down the home and volume up buttons for around 5 seconds then let go of everything. Recovery console should appear on screen.
To enter download mode: Switch off your phone, hold down power button AND volume up button AND volume down button. Warning about custom OS's should appear, followed by download mode after pressing volume up again. If this doesn't work try taking out battery, sim card and SD card, connecting USB lead (screen will be completely powered off) and then trying the key combination.

Remove the battery for a few seconds and plug it in, then do this.
Push the volume up + home button + power (start with volume to home to power, keep holding all, dont let go) until it boots.

Good, apparently you are a major noob ( ), do read some guides before doing anything from now on.

SM-T710 Cannot boot into recovery (or otherwise) after trying to upgrade TWRP

My Galaxy Tab S2 had a fairly old version of TWRP installed that wouldn't let me install more recent ROMs. So to update it, I followed the first set of instructions here (which was probably a terrible idea). I then told it to reboot to recovery. It rebooted, but froze on the initial "Samsung Galaxy Tab S2 Powered by android" image (not the animated one). Now the only thing I can do that gets any change is to hold power + volume down for a little over 5 seconds. This causes the screen to go blank briefly and then it goes straight back to that same graphic. I've tried holding power + volume up + home, but get no response.
Have I permanently ruined my tablet?

SM-T510 BOOT LOOP issue

Hey guys,
So I'm having issues trying to fix my Samsung Tab A 10.1 ( SM-T510 ).
At first I was trying to install a custom TWRP recovery image, and I had a boot loop where it kept getting stuck at the SAMSUNG splash screen(not the initial samsung boot screen that shows TAB A 10.1). I however overcame that issue by factory reseting and through some additional tinkering.
Now the part I'm starting to regret.
I tried once again to flash the custom TWRP to the tablet, but this time I forgot to tick the "autoreboot" setting off.
So ODIN shows a PASS for the flash, but now when the tablet boots its stuck in the following boot sequence:
START:
Initial Samsung boot screen asking to press power button to continue due to unknown boot image source etc
PRESS POWER
SAME INITIAL SAMSUNG BOOT SCREEN minus the power button prompt, lasts for about 3-5 seconds
REBOOT
Now I have managed to get into download mode with the tablet connected to a computer.
I CANNOT get into recovery mode to factory reset the tablet, which was the solution the last go around.
I am starting to think that the only way I am going to get the tablet back in original working order, or any working order for that matter is to:
A: LOCATE original firmware for my device, I believe it is GTAXLWIFI firmware for my device. However the files I have found don't seem to be accepted in ODIN...
B: Try to continue on with the TWRP process, which I have tried to reflash the TWRP recovery that I have, and it shows pass. But, the issue persists.
Any suggestions or help would be amazing!
Thanks!
Timing is the key
Set your finger on position where you gonna restart the device.
Hold power + vol down
After the screen restart switch soon as possible you finger to set to recovery by
Hold vol up + down + insert the USB C cable
Remember timing is the key. I have done this for several tabs that screw on my home so you are welcome bro

I think "restarts" may be confusing. Switch from down to up as soon as the screen turns off.

You can use frija.exe to get the latest stock firmware. To get TWRP you MUST boot to recovery before system. If you allow the tablet to boot to system first, it will overwrite TWRP with the stock recovery. Do this by pressing vol down and power till the screen turns off. As soon as it does, switch from vol down to up while still pressing power and keep holding both till the red warning message appears. You also need to leave the cable attached to the PC while doing this.

Note 9 bricked

Hi I need some help here. I have uninstalled magisk on my phone and now my phone is bricked. I cant go into recovery mode despite trying all button combination. If i were to plug in a charger. The phone will be stucked at the charging logo screen. The only button combi that is working now is power and volume down button which will reset the phone but the phone will get stuck at the loading screen. i have a Samsung note 9.
so you also cant go into odin mode?
power + bixby button + volume -
if you could still get into odin mode you could at least flash the stock rom with odin for pc
