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,

Hope this helped.
Thanks.
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?

my nandroids were not visible... like,wtf,I can't find any of my backups, twrp isn't showing internal or external SDS...weird
Just bricked my Galaxy Tab S. Got it off and it is showing the battery sign. During TWRP I somehow wiped the internal sd. If I download a T800XXU1ANJ6_T800XAR1ANI1_XAR.zip will I be able to ODIN it back to stock? HELP
Lost my backups
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!

Just bricked my new Tab S and could not shut it down. I also deleted my sd card during a TWRP move so found the firmware and back to ODIN and I am on my way to recovery, but first thanks is to you to save me from my panic!
Appreciate your advice in getting tab off and back into recovery. Whew!

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 Everyone
TL;DR Screen doesn't come on at all, battery led only flashes while it is rebooting (More details below), and When plugged in to my windows pc, a bunch of "Local Disk Found" pop up, some of the volumes I can access, most I cannot.
I have searched and searched the internet the past 24 for solutions, and have yet to find one. So imma walk you through what led up to the issue, as well what solutions I have tried.
Yesterday while I was trying to update my rom, I ended up getting stuck in what I thought was a boot loop. I then decided to hard reset my phone and go into recovery in hope to try to reinstall the rom. To my surprise, I could not access the internal sd card in the phone. Data was unmounted in the "Mount" settings and I could not what so ever remount it. After this I tried to side load it, but to no avail.
In response to all my attempts to fix the phone at that point, in frustration, I just said "**** it" and went into factory reset in the bootloader. This is where the hard brick happened. At this point, the screen would not come one, and the battery led was not lit when plugged in. I tried letting my phone charge over night and then, tried the "Battery Recalibrate method". I then tried the "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader"
After that, I then thought that the firmware was corrupted, so I tried to see if I could push an img to the phone, however fastboot does not see the device. I tried RUU, it does not see the device. I tried the HTC Unbrick method by Dexter that required me to install ubuntu and do some things in terminal, that also did not find the device. And here I am stuck. One thing unique to my situation that I have yet seen reported in the countless threads I have searched, is that when I plug my phone to my pc, a large amount of disk drives are found. Most of them are not accessible, but there are a couple that I can go in and see files for. Windows asks me if I want to format the ones I can't access. When hooked to my pc, I tried the the Power + volume button combinations, the only thing that seems to happen off of this is that my phone seems to reboots, and the battery indicator briefly shows.
Anyways, this is all I can remember. Any help would be GREATLY appreciated. I don't really think it is a hardware related issue since my phone does somewhat boot. However it seems it can't get to a bootloader what so ever.
Try holding power and vol up for a long time, like a minute or more. Try with and without charger attached, and after sitting on charger overnight.
If the bootloader is intact, the phone is likely not truly bricked (recoverable). And I don't see how you could have damaged hboot by the actions you mentioned.
What is the phone's original CID (carrier version) and are you s-on or s-off?

Verizon is the carrier version, and I am s-off.
Held vol + up for 5 minutes both with and without the charger. One time with the charger into my computer, and another into the wall. When it was in my pc, I can tell its doing nothing but rebooting over and over by the notification sound, and the constant "Found new disk" notifications I got. However still no luck, no screen turns on, no sign of hboot. I'm hoping to have some luck after leaving it on charge overnight and trying again.

So still nothing after leaving it on charge overnight and I held vol + up for about 5 minutes. Things seem grim.
I think the proper thing to do when you discovered internal storage was not mountable, would have been to use the TWRP option to format internal storage (in Advanced Wipe options).
But now I'm baffled as to what happened that would have rendered the phone unable to boot into fastboot mode. Fastboot won't recognize the device if you can't boot into fastboot mode, which leaves use kinda stuck.
So you didn't try to flash anything during the course of all this troubleshooting?
What you did - "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader" is totally wrong
I used to get this bunch of local disk pop-up and this is how I get out the problem
Connect the device to pc, you can hear notification sound on pc that device is connected. Ignore all those bunch of local disk pop-up
Press & hold both power button & volume up button until you hear another notification sound that device is disconnected from PC (that's the indication that device is restarted)
Release both power & volume up button and quickly press & hold volume down button (only this one button)
This should get you on bootloader

No, nothing was flashed except the original Rom update that got this snowball rolling (Not saying its the roms fault, most likely mine).

This is the one combination I forgot to mention in the op, sorry for that.
But I have tried this, before and after your post, still no luck.
If it worth mentioning, I can just hold power + down and it still reboots over and over. As well as just power. As a matter of fact, all button combinations reboot the phone over and over.

I thought the screen was dead? If so, how do you know its rebooting?

By it constantly connecting and disconnecting from my pc. If that doesn't mean its rebooting, then I guess I'm mistaken.

Well, it might mean that.
If it in fact is rebooting over and over on its won, simply holding the vol down button for a long time, should put you into bootloader (on the next reboot "cycle"). Again, assuming it is in fact rebooting, and that bootloader is intact.
I recently upgraded to the eonon GA6151 and was trying to flash update_RK3188_1024x600.img " booroondook RK3188" , well I renamed the file wrong to dupate.img instead of update.img I started flashing it and it was too late before I realized. Now the unit will not boot up or go to recovery. I can reset it and see the buttons flash like it wants to go to recovery but nothing ever appears on the screen. Is there a way to adb into this unit? Can I put files on a card and have it auto install them? Any help would be appreciated.
FIXED IT!!
I fixed it using this method. I realized after the fact that this new unit is MTCD not MTCB.
https://forum.xda-developers.com/showpost.php?p=67184851&postcount=50
I then had the error
https://forum.xda-developers.com/showpost.php?p=67309331&postcount=116
Which I fixed doing this
https://forum.xda-developers.com/showpost.php?p=67598154&postcount=319
I used the dupdate from here.
http://huifei.fs-fileserver.de/content/firmware/MTCD Custom ROMS - NOT FOR MTC-/RK3188/2017.02.21/
I loaded it onto the sdcard and the usb drive , the sdcard was created using upgrade disk tool and has to be 16gb or smaller fat 32. The usb drive just had a copy of the dupate.img file on the root of it.
To get into recovery on this unit do the below. http://www.eonon.com/Android-Car-GPS/Vehicle-Specific-GPS/GA6151.html
Press and Hold HOME AND POWER buttons
Press RESET while still holding HOME AND POWER
Let go of HOME AND POWER and then press HOME AND POWER down again and hold until the lights flash 3 times " is about 10 seconds to hold them "
Now Let Go of the HOME button then the POWER button the press the POWER button once "do not hold" and wait for it to boot into recovery.
This is the only method I found that reliably will get you into recovery. Make sure you use the GPS slot for any sd stuff you need to do in recovery.
Did you have to take the unit out of the car? I’ve made the bootable SD but nothing is happening.

Hi all, have two problems:
1) My power button stopped working long time ago. But it's some mysterious. It doesn't turn off or on screen and it doesn't accept options in bootloader. But it DOES reboot tablet if I hold power button.
I was trying to clean button with alcohol and make it work, but nothing helps. I think that button replacement won't help (I didn't try).
2) I wanted to install new ROM, but I can't. I stopped after flashing recovery, 'cause "No command."-screen appears, where I should use my NOT WORKING power button.
So my questions are:
1)any suggestions about the problem with power button? (Solution of this problem will solve second problem)
2) how to enter custom recovery without using power button if I had "No commans." stock recovery screen?
Thanks a lot!
Type "adb reboot recovery" from inside Android. Same for rebooting to fastboot or bootloader. It's easier, especially on the Pixel 2, than trying to get button presses correct.
If you can hold the button down and reboot it's apparently working physically.

Thanks for quick reply.
Yeah, I enter recovery by "adb reboot recovery", but I have then "No command." screen where I need my power button to skip this screen and enter TWRP.
I've not seen that screen with TWRP, only with the stock recovery.

Interesting. I opened my N7 to check the buttons connector's configuration. Please verify the following:
disconnect the battery and measure pin 1 and 8 with an ohmmeter while pressing the power button - I get <1oHm (short)
reconnect the battery and measure voltage on pin 1 - I get 4.0V
Well?

Have the same with yours
The randomly went into boot loop. I followed this guide suggested by @blackhawk in this thread https://forum.xda-developers.com/t/mystery-stuck-at-boot-screen.4518803/, still no use.
I tried the following things:
1. Connected the device with pc and pressed the volume up and power button to get to recovery mode(no response ).
2. Performed soft reset by pressing volume down and power button(still went back to boot screen).
3. pressed tried to get to recovery mode by pressing power button and volume down after the screen went blank pressed volume up and power button to try get to recovery mode(went back to boot screen).
PS:
The device was working fine until it went into this button in a bizarre fashion.
The device has only play store approved apps.
No attempts were made to unlock bootloader or flash custom rom.
Battery is known to be good right? No rear cover bulging? If any doubt, replace it. A fair amount of power is needed to boot.
Otherwise...
Try to get it to go into safe mode, if that fails...
Factory reset from recovery menu. If that works the data user partition was corrupted likely by a 3rd party app or malware.
If that fails reflashing the rom is the only thing left to try. If that fails it's a hardware failure.

First of all thanks for the response it really means a lot
The response to the points mentioned:
1. The device looks healthy with no rear cover bulging.
2. I am unable to get to the recovery mode at all, any combination of button I press gets me back to the boot screen.
3. my laptop is not recognizing the device so i am not sure how to go about reflashing the rom.

You're welcome. Sorry to hear of all the trouble you're having.
If you can't access recovery mode ie boot menu you have big problems. Try to do it again plugged into the PC; the newer ones need this to access recovery mode on the Android I think.
Make sure the button sequence and timing are correct. Sometimes I goof it twice in a row
Try removing SD and sim cards. Does charging show on the display? Make sure it's at 70% or more.
Otherwise could it be a failure on one of the buttons? A cable may loose? I don't think a C port failure would cause this but not sure if that's always true. Unless dropped or water damaged mobos rarely fail but this is a possibility.
Maybe someone here has a better plan...
