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?
I looked around and seems that I'm not the only one with the problem, but none of the things that worked for other people worked for me. I seem to be another victim of the dying Motorola's.
I had just sent a text on my Motorola after unplugging it from the charger in the morning, left it for half an hour, and when I came back, it wouldn't turn on. Did the hard reset button combo, nothing. Physically disconnected the battery, nothing. Plugged it into the usual charger I charge it with (from a Galaxy Nexus) and nothing but a solid green light. Plugged it into a higher current charger (from a Blackberry Playbook), green light flashes and it turns on, but only to the Motorola logo.
It only seems to either go into the Motorola logo, the boot selection screen, or AP Fastboot. Nothing else. Unplugging the charger once on will kill it, so looks like it isn't getting anything from the battery. And also, once on, it hard resets itself after about 20 seconds. It just shuts off, then green light flashes, turns on, runs for about 20 seconds, then repeats.
I hear a new battery fixes it, but I had already put a new screen on this thing, a new LCD, a new back, and unlocked it, I'm really not inclined to replace another part in it. Does anybody have an idea of what's going on or what I could do?

If you can get into Fastboot, then you are not hardbricked. I don't think there's TWRP for your phone, otherwise you can charge while in that recovery; I think you are going to need to buy or make a factory cable in order to keep the phone on to get it running again http://www.droidforums.net/forum/droid-labs/146492-how-why-make-your-own-motorola-factory-cable.html

Darn. I managed to get an OEM charger for a Motorola (from a RAZR HD) and it does the same thing as the Playbook charger. Turns on, but only to M logo or fastboot, and auto resets after about 20secs.
Ya, the oem cord is not a factory cable

Managed to finally get it working! I plugged it into the Playbook charger and as soon as I plugged it in held volume up+volume down+power to get into boot selection menu, select Recovery, and just let it sit at the red M logo from morning until evening. I went to unplug it, and it stayed on! Held volume down+power to reset, tried turning it back on and success! It works again! :laugh:

I'm having the same problem, I was wondering if you'd be able to help me get my phone working again. It does all the things you described in problem, but I'm not as technologically savvy as I'd like to be and haven't the slightest of how to fix this. Any response would be greatly appreciated!
Hello guys,
A while ago, I was just doing stuff I normally do with my phone. I flashed a ROM and it rebooted normally. I then flashed a MOD using TWRP recovery. As usual, every MOD that uses Aroma Installer has a "Reboot device after install" option so I chose that and then **** happened.
Out of nowhere my One suddenly shuts off (The install was done so...)
I have tried the sensor under bright light trick and my phone does vibrate once but nothing actually happens. Just a black screen and stuff.
Sometimes it does go into this screen where it shows a battery icon with thunder bolt in the middle (Yes I know that is the charging screen. But, I also believe that it acts like a progress bar and it does not do THAT.)
Then again, it dies and it doesn't have the charging LED nor would it turn on.
Help is appreciated. I know basic and complicated android stuff but I can't do any of that if my phone is dead
Edit: When I press the power button for a few seconds, it vibrates but nothing happens. The screen is still off and the charging LED is not turning on as well.
Edit: Okay, when I do get it to charge, it shows that charging screen and when I unplug it, it freezes with the charge light on. The phone is also heating up so that does mean it's charging
Regards,
TAM

No. But I was able to drain the battery and once I plug it in using the original HTC wall charger (which is the one that I always use to charge it.) it charged but the charging LED is blinking (mut have drained it self good overnight) am I making progress or did I make it worse?

It's difficult to say at this point, Personally I would just leave it charge over night. Then try and power it on with Volume Down+Power while still connected to the charger. And it definatly doesn't show up in device manager, not even as Unknown Device or QHUSB_DLOAD? I find that a little odd.
But there are signs of life so I think a good charge may do the trick.

Yes. I did plug it into my laptop's usb ports last night when it still had charge (usb 3.0 if that helps) but it was neither recognized nor visible in the device manager. I hope! I am now charging my phone as we speak. I hope it's not dead too
Okay so...I installed HTC Sync and still nothing. It was not recognized and it's still not booting
Try Windows 7 USB 2.0
just htc Drivers
Try to go to Boot loader and flash firmware
if it show battery with charging sign it means Soft Brick or battery problem
if it showed nothing like no charging light or nothing on screen then its Hard Brick

Then it is probably a soft brick or a battery problem. Because when I got home I immidiately pluged it into the wall charger for it to charge and it charged showing the charging screen with a blinking LED. One more thing, if I press the power button for a few seconds it vibrates and then nothing happens. I am planning to leave it charging over night. Is that a good idea?

can I ask what your flashed before it did this ?
also crazy question, but have you tried holding down the power button till the lights on the bottom flash approx. 12-15 times ? this resets the device, Ive had to do this after many flashes of various things.

I was flashing a MOD then after the installation finished, it asked if I wanted to "reboot now" so I tapped yes then the phone died and it won't start anymore. Yeah but how long should I hold the button? Just to clarify, my phone only vibrates if I hold the power button for a long time. It just keeps vibrating and vibrating

until the lights stop flashing, usually about 12 or 15 times cant quite remember exactly how many times they flash but its quite a few.
I know you said you tried the bright light trick, but you should also try this trick whilst holding down the power button.

Umm...but the buttons don't light up when I press the power button for a long time.
It does this but when I unplug it, it freezes like that with the LED on.
Edit: When I plug it in the computer it doesn't show up (I think that's good because it's a sign telling me that maybe the phone just needs a long ass charge). Now I will be leaving my phone to charge over night and hope that it will boot up in the morning. The phone becomes hot too while it's charging.
Note: I also do not have access to RECOVERY, BOOTLOADER and FASTBOOT.

if your phone is in warranty you should go to service centre
This situation is quite confusing
as not accessing bootloader is not good sign

Okay so I plugged my phone into a laptop with USB 2.0 ports and it showed up in device manager as an "Unknown device". Not sure if it was caused by the phone showing the battery charging screen but anyway that happened. Is that a sign of life? What should I do about it?

What version of ubuntu do you recommend I use? I will be installing it on my flash drive so...
Hello folks. thank you in advance.
I'm 99.9% sure my phone is done. I checked the forums and found similar issues - but nothing exactly like mine. after five day here is what happened, and my troubleshooting steps.
the issue started five days ago. my phone was plugged into my HTC wall charger, which was plugged into a power bar connected to the wall. I made dinner, ate, and came to get my phone.
the lights under the back and home buttons were lit up, but the screen was not. I pressed the unlock button
nothing happened.
I did it again
nothing.
seeing no other alternative I held down the power button until the lights flashed and the phone should have rebooted - instead, it shut off and never turned back on.
I pressed the power button. tried the volume down + power to access the bootloader for an FDR. but the phone still wouldn't power on.
I figured something was up with the battery. I plugged it in for a few minutes but the charging light never came on - it never even blinked.
so I charged it overnight.
the next day, the same thing.
no power, no charging no blinking.
I tried the wall charger, I tried my PC.
that was when I got a ray of hope - my laptop made the USB-connected jingle when I plugged the phone in. so I let if charge, but there was no light
this was when I turned to the forums.
I tried resetting the charging logic - charge for 10 min, unplug, hold down vol+ vol- and power for five minutes
five minutes and three very sore fingers later nothing happened. I tried the same thing holding the proximity sensor under a bright light (super blackout flashlight).
after this, I resigned myself to plugging the phone in for four days. it has been plugged into the wall charger since Tuesday. no red blink, not green light and still not powering on.
i'll also note that when the phone is plugged into a PC it show up in the device manager under the section "ports (com & LPT)" and is called "Qualcomm HS-USB QDLoader 9008 (COM4)".
i have also tried to boot the phone manually the ADB but it just says device not connected.
thank you in advane!
From what I know, if a phone is called Qualcomm HS-USB QDLoader 9008 (COM4) (or anything with he first three words), then it has a hardbrick or is (sadly) dead... I can't help you, because I don't know how... I never had such a problem [emoji52]
Your phone can go in QHSUSB_DLOAD mode for 2 reasons:
Flashed an incompatible firmware ---> Recoverable
Hardware failure ----> Phone is dead (or will most likely need a new motherboard)
Since it went in this mode itself, then its #2.
Hi,
After many years of enjoying this magnificent phone the disaster came.
The phone discharged overnight and switched off. In the morning I had to send some texts, so plugged the wall charger into USB socked (a weak one ~500mA), after few moments a charging icon appeared and stated that battery has 1%. Ok, I really had to send those messages: I've pressed the power button and phone started to boot.
Sony logo: OK, purple wave, OK...
After 10-20 seconds it suddenly switched of, red LED started to blink.
I thought: OK, system startup needs a lot of power, maybe a charger is too week to keep up.
So I left phone for few more minutes to charge, but without success.
That was the last time I saw screen was on.
Phone is a C6903, running on a stock, rooted 14.6.A.1.236 with the recent XZRecovery.
Bootloader has been unlocked.
For the moment I've tried everything but opening back and doing the testport-trick.
When I connect the power only red led blinks (I left the phone charging overnight, no change).
When I try to enter flash mode: nothing happens but red blinking light.
When I try to start phone nothing happens at all.
But there is still hope:
I connected the phone to 2A charger using a magnetic cable.
Then I've connected normal USB cable to my PC, strange thing started to happen:
When I pressed volume Up (even after few minutes of connecting power+usb) the phone suddenly jumped to fastboot mode (blue led, it was discovered by PC, fastboot terminal was functional)
When I press power button, phone vibrates for a second, then the led pattern changes to: 1s red followed by 0.1s green, then long red, then it repeats...
I'm still unable to enter any recovery nor flashmode...
I'd really appreciate any help, have you got any ideas left how can I revive my phone?

Hi, this just happened to me, my phone has been dead for over 4 weeks with just the red led blinking. i tried the test point thing with no success at that point I gave up but last week i decided to get a new genuine battery and it worked it booted up. Your battery is just completely dead thats why it won't boot up!

Yup! That was it (at least I think so, I don't have new battery yet)
The Al part of positive battery terminal was broken: I have no idea why, maybe because of age, oxidation and high currents that were drained from this LiPo cell...
Anyway I've managed to temporarily join two broken Al parts, kernel and recovery booted successfully.
Now I need to wait for a replacement battery.
Phone is alive again, thanks tilakpatel for help!
But the magnetic cable trick might be useful in other hardbrick cases: just connect magnetic charger, connect normal USB cable to PC and hold volUp. Phone should be able to enter fastboot even with completely drained battery...

Anyway I've managed to temporarily join two broken Al parts, kernel and recovery booted successfully.
Now I need to wait for a replacement battery.
Phone is alive again, thanks tilakpatel for help!
But the magnetic cable trick might be useful in other hardbrick cases: just connect magnetic charger, connect normal USB cable to PC and hold volUp. Phone should be able to enter fastboot even with completely drained battery...
