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 am on stock everything except for recovery, I would like to bring my phone into Verizon to get it replaced because of my myriad of issues, but I am unable to install stock recovery. These are my issues:
1.) Phone is not charging, I have tried the original charger + cable, and at least 5 others, nothing is working. I can boot the phone and use it but its stuck at 0% (sometimes it goes up to 2% but never higher)
2.)Whenever I plug the phone into a power source or to the PC it shuts off and restarts
3.) I cannot get into download mode to install the drivers, I hold VOLUP and then plug in the cable, and it says download mode, but then it shuts off again and gets stuck in a bootloop until i unplug the phone, and then power it up without the cable in it. Which is an issue considering the battery never goes above 2%
4.) Phone is in near-perfect condition, minimal cosmetic damage and no scratches on the screen. So it cant be accidental damage.
anyone have any suggestions? I would just take it into verizon but i have TWRP recovery, and im afraid they will charge me if they find out.
I flashed CM 12.1 a while ago and it would sometimes freeze up so I would pull the battery if vol down + power didn't work (which it usually didn't) and then last night it just turned off and never came back on. Sometimes it would boot into download mode and say "failed to do normal boot mmc_read failure" and others it would boot back up no problem. Now I can't get it to boot into Recovery or Download, I've taken the battery out and help down power for a while, then put it back in and help power for a while, tried charging with two cables that both charge my tablet just fine and in two outlets. When I plug the phone into the computer it dings so the PC recognizes a device is being plugged in but it doesn't show up under the file browser. Am I hard bricked? Can I fix it? Should I try to get a new phone?
It's a T-Mobile Note 4 if that helps. I'm still making payments on it but I passed the year mark in February.

I looked up that error and there was multiple articles thatvsaid it could be a flash memory error of an EFS problem. Hopefully its something different, as both of those are tricky at best. Its a place to start though.
Install Kies and try the emergency firmware recovery.

I have a big problem on my Moto G (2014), I am soft bricked and with 0% battery. I can get into fastboot mode and I'm able to flash TWRP and official roms. But they won't boot. After restarting to recovery or rom it will show the "warning bootloader unlocked" for a minute and then the "0% battery left" screen. After that it boot loops. I think it's because the battery is so low that it can't boot recovery or to official roms.
At this point I'm in fastboot mode and connected to my PC so it's charging but very slowly and often times it exits fastboot mode on its own and tries to boot, how do I prevent that so I could leave it charging for overnight? Or any other suggestions?
Thanks in advance!
Try putting it in the bootloader menu by pressing vol down and power and don't use PC to charge its very slow in these situations and quite inadequate ,plz use a proper phone charger with higher miliamp ratings and it should charge up and let you boot properly. And if it still does not boot then the battery might be gone , have patience while charging it takes a long time to recover from this situation.if all fails then you might try to reconnect the battery header on the phone motherboard but that requires the phone to be disassembled ,check out YouTube for the instruction vids....hope it helps
Try offline charging.
So I dug my old Motorola droid 4 out of my drawer and decided to fix it. I soft bricked it a while back and just gave up on it. However during this quarantine I've been very bored.... lmao. So I replaced the battery. and now I'm still getting this "Unable to program, Battery low". I understand that it needs to be charged, but how? Everytime I plug in the phone it tries to boot, but of course its stuck so it wont. it just keeps cycling with the "M" logo. and it doesnt matter what phone cord I use, it just turns the device on without charging it. is my phone ****ed? or is there a way to charge it? cause it just wont charge.
Have you tried to charge it up after turning it on not by "standard" holding POWER button but after using [VOL+] + [VOL-] + [POWER] key combo?
There are several options there showing up so the device may be able to enable charging with selected one of the options or at least while showing the menu.
I am not 100% sure if this would work but this would be the first place where I would look for ability to charge the battery without any OS to boot up.
I had the same problem some weeks ago and I found two ways to solve it.
Since you can't charge the phone you can only replace the battery with a charged one (type EB41) or buy/build a fastboot cable (https://forum.xda-developers.com/showthread.php?t=1077414).
I had this problem before too. you can make the fastboot cable. USB Micro cables sometimes have the 5th pin populated, and you need to solder the vcc wire to the 5th pin and it will allow you to flash the phone in fastboot mode. it will simply remove the "battery too low" message in the fastboot screen and replace it with "usb connected" or something like that. It's been a long time since I've used it, and I've since found an eBay seller that has bulk OEM batteries so I bought a few and they've been great.
just search for "make your own fastboot cable" because I can't post links here.
