[HELP] Strange Soft Brick issue

Hello all,
I searched around, but didn't find anything quite like my issue so figured I'd create a new thread.
I work for a company that uses Galaxy Tabs for various purposes. One of our men brought back their VZW Galaxy Tab (SCH-i800) and it was in an infinite boot loop.
I went to recovery and attempted to do a full wipe. This did not work (partitions were all jacked up) so I couldn't get it fixed. I'm not sure if the guy tried to root the thing and broke it or what.
Anyway, I was attempting to root then fix the partitions (then was going to flash a stock unrooted rom) and ended up soft bricking it (Phone Icon -- /!\ -- Computer Icon). The issue I'm having is the only time that screen comes up is when the device is plugged into the wall. It turns on, then off, then on, then off. If I unplug the device, it shuts down with no way of bringing it back up. I've tried holding power for 5 minutes, the same amount of time with power + vol up and power + vol down. Plugging it into the computer's USB ports does not help either.
It's like the battery is drained but it won't charge when it's on the soft brick screen. I've had it plugged in to the wall for almost 6 hours now with no hope in sight. When it's plugged in, I feel heat on the back of the device like it would normally be charging. The AC adapter is also the standard warmth after a lengthy charge.
I was wondering if anybody has had similar issues with this device and if there is any way to correct it.
--- EDIT 8/10/2012 ---
Another thing of note is when the device is charging, I can power it down by holding power for a few seconds, but the Soft Brick screen pops back up almost immediately upon release of the button.
I cannot boot into recovery or the standard download mode even when it's plugged in.

As long as you can get the Phone ! PC screen, your'e good, because this screen IS as a download screen. Go to this screen and flash a known good ROM.

You must not have read the whole thing. Not a problem.
The only time I get the Phone ! PC screen is when it's plugged in to the wall. As soon as I unplug it, it goes away and the device won't start up no matter what I try.

When you connect the tab to the pc, is it recognized by Odin.

No... When the device is unplugged from the wall it is shut down and won't boot back to the download screen, recovery, nothing. It doesn't turn on. There are occasions where the download screen stays up but it appears to just be frozen. The computer doesn't recognize it and neither does Odin.
I left it plugged in when I left work on Friday... Going to see if charging for the weekend does anything.

No dice.. still jacked.
I determined the following scenarios may have happened:
1) The battery died (bad battery) during a software update and messed up the partitions
2) The battery died (bad battery) while he attempted to (unauthorized) root or flash the device, messing up the partitions.
The only thing I'm sure of is the battery is fried so any kind of hacking I can do to the device are for naught. I was able to get it to connect to Odin this morning for about 3 minutes (after having it plugged in to the wall all weekend). During the flash it shut down again bricking it even worse. Now the device won't turn on when plugged in to the wall.
Thanks for the suggestions and help. I'm calling this a lost cause at this point. We're just swapping out the device for a new one. Once that's complete, I may tear the device down and try to do a reset on the main board to see if that does anything, though I doubt that's the case.

Right I had exactly the same problem as you (exactly the same symptoms) but I have now fixed my tablet.
Like you I got to the point where the Tablet had enough charge to actually unplug it and connect it to my PC where I then tried to flash a stock ROM using Odin. About three quarters of the way through flashing the stock ROM the tablet died, disconnected from Odin and I got a message in the task list in Odin advising me that the process had failed. Even weirder my PC did an emergency shut down and restarted in safe mode.
Anyway I tried it again but when I started my machine, once I'd logged onto my desktop I started up Odin as quickly as possibly, selected the .tar file and pressed start as quickly as possible....it worked and my tablet was flashed with a stock ROM. However my battery was still pretty much dead and the first time of charging once it had been flashed with the ROM took about 24hrs plugged in at a mains charger for the battery to reach 100%.
My point is persevere with it and you will fix it. I was at the point where I was about to send it off to be un-bricked but obviously I'm glad I didn't now.
It is a ***** of a brick though, this 'coma brick'.

I've been having these same issue with my friends i800 galaxy tab. Can you chime in and offer some advice?

same problem-solved
I was having the exact same issue. the device screen was completely black when plugged into the computer. I was just about to give up when, all of a sudden the device went to the boot error screen while plugged into my computer. Apparently, it must remain plugged into the computer for about 20-30 minutes. Once this screen appeared, I ran the Heimdall one-click unbrick utility, and like magic, my galaxy tab was working again. Give it a try, and good luck.

I am having this issue with my sch-i800.... phone /!\ pc screen only when plugged into the wall, and no recognition of it on the pc. Any way of fixing it?

Stuck when rooting. Help please!

I was doing this tut, forum.xda-developers.com/showthread.php?t=1852546 , and I was at the part installing JW4. (I dont believe my phone was the i9000) anyway, It says...When it finishes, your phone will automatically reboot, upon which you can unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin.
This did work, and it did say pass. But it never rebooted. When i tried to reboot, it wont turn on. It wont boot into recovery, or download mode. I dont know what else to do at thing point. The battery was charged, and when i plug it in now, no light showing charging etc. Any idea would be great. Thanks.

Try to remove your battery to 15 minutes and then instert it. And launch Download mode again

Tried, still wont boot into anything. Tried every button combo. Tried removing battery and holding power for a minute. I'm still getting nothing though

Has my note hardbricked?

Yesterday i was recording video on my note, and when i stopped recording, it got stuck on the screen. after waiting for some time, i had to hard reset my phone. I pressed the power button for a few seconds and phone shut down. But it refused to start up,however hard i have tried. I tried booting to recovery and download mode....but still nothing happened. It refused to enter recovery or download mode...:crying:
I got home and tried to connect to my pc, nothing hapened. I tried charging it, but no signs of charging. Tried ADB, couldnt recognize my device...
I was on Aylum 4.4.1(6 DEC nightly) using herna's kernel and rooted using SuperSU 1.80. No extra mods installed. Was running fluidly for 2 days...no freezes,etc. And suddenly died....
Please guys help me out. Is my note bricked?

Try removing the battery and waiting 10 minutes. After that then put the battery back in and try to boot it up. If that doesn't work then try a different battery in your phone or try to recharge you current battery through a recharger (you can buy them on ebay)

my phone stop responding sudden death Z3+ e6533

I have Xperia Z3+ dual E6533 that was on custom ROM working fine for almost 4 months.
suddenly after installing Xposed framework second day while on ultra stamina mode once I try to deactivate it and go back to normal it goes into boot loop.
once I turn off the phone and let it charge to 100% tried again to boot but still the same so I left the phone for a couple of hours to be cool down after around 15 min boot loop.
suddenly it's not responding anymore for any key combination or hard reset or reflash.
I tried hard reset by the small button next to sim card slot, by (Power & Volume +), by removing the battery and reinstall it again.
now the computer does not recognize the phone at all and cannot go in flash mode or fastboot mode.
I tried also holding the volume- before connecting the phone and holding it until connecting to PC but nothing showing in device manager.
now all that is coming that once it's connected to wall charger it's blinking red for 2 days now and while pressing the power button the blinking red light turns into stable one not blinking.
I have already read most of the similar issues written for other devices and tried most of them but still nothing.
can anyone help me?

SM-T800 boot-loops and dies the moment you let go of the power button?

I've got an SM-T800 behaving very oddly, hope someone knows what's up!
If you attempt to boot it, it will flash up the Samsung logo, then die, and repeat in an endless boot-loop.
If you hold the power button down, oddly, it changes; instead it will proceed to the animated SAMSUNG logo which will then continue to pulse in and out indefinitely until you get bored and release the power button... at which point it instantly dies and then begins boot-looping again.
If you try to enter recovery by holding power + volume up + home, it will do so, but the moment you let go of the power button it dies.
Thinking it was down to the battery, I tried replacing it, and if anything the behaviour has been worse since!! It was at least possible previously to get the thing to sit in recovery without rebooting, but now it never does if you let go of the power button.
I've also tried reflashing the default firmware via ODIN; the one thing that always works is the download mode (power + volume down + home); I can reliably boot it into download mode and flash via ODIN, but then on reboot, it gets partway through the installation process (like a few seconds in) and then boot loops back to the samsung logo again.
Now it's difficult to get it to even charge; it will keep looping the charging symbol (battery with a lighting bolt on it) on and off the screen unless you fettle the buttons until it just sits at a black screen. I can see from the USB charger it is still drawing charge current.
Any ideas??!

It probably dead. Speaking as someone who had this issue for countless devices, I say that your battery probably can't hold enough charge anymore to completely power the device through.
It doesn't matter even if you charge it to 100%. The battery had degraded to a point where a minimal charge required to let the device pass the crazy power surge required during Android boot is just not meeting the minimum.
Hence it fizzles out. And rebooted.
I kept replacing my Galaxy S5 battery until few months ago, no battery I bought is enough to fully power it on anymore.

Thanks for the response; alas, I already tried replacing the battery; if anything it was worse! I suppose it is possible that the replacement battery was also a dud, though? Unfortunately it may be difficult to do a load test (a lot of batteries might not even provide power without specific conditions being met), perhaps I can probe the pins while it tries to boot and see if the voltage sags or something.

I have the same problem and I found this in Yoube; search for "Samsung galaxy tab s restarting issue" video from "Electronics repair school"
It shows bad contact on battery connector soldered side...

I have the same issue, I can hold down the power button and it will boot up completely. As soon as I let go, it reboots over and over again. So far I've replaced the:
USB Charger Port Connector Module Flex Cable
LCD Connector Flex Ribbon Cable
and the Battery
No change in boot up - The only option left , I think, would be to replace the main board. Any thoughts?

i got that issue too,
i did kind of a battery recalibration
meaning: i fully discharged my sm-t800 (took me some time doing reboots until the tab was totally dead)
then charged it to 100% without booting it
unplug it and reboot.
and well, now it works again
the clue here is:
the system stored wrong battery data over the time, so it randomly thinks the battery is at 0% and does an auto-shutdown. To repair this, you have to reset the system with recalibrating the battery, so the system deletes all old data and starts logging new data.
in my case this procedure worked out great
hope you guys will have the same success as i did

Hello everybody!
I thought I would let you know how I solved this issue WITHOUT having to do a full factory reset...
Or so I thought.
Turns out that it started shutting down and bootlooping after a while again.
Even after I ordered a replacement battery and charged that up. At first it looked like it would work and then it started shutting down randomly and bootlooping.
Probably will have to throw the thing out since it doesn't want to work. Makes no sense how its so uncooperative even after putting in a new good battery in the tablet but there's not nuch more that can be done.
If I just start it *sometimes* it will boot up and get to the android OS. Then work for a while before shutting down.
Sometimes it just bootloops at the Samsung Galaxy S logo over and over.
Holding the power button it does boot but if you release the button it MOST often just shuts off and bootloops.
Anyone know if there's anything to be done to fix this?

I have had the same experience with my T800. What I have been doing is to tape the power button down using scotch tape. The tablet can be waken up by pressing the home button. In my case, I need to remove the button to recharge the tablet.. So far so good.
