[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.

[Q] XT894 Charging Issue

I'm new to this forum, and am in dire hopes that a workaround can be resolved for my issue. I've read a lot of posts here, and I've found people definitely know what they are doing here.
I have an XT894 (So I believe this is the right place).
I had this issue before, and I just ended up replacing the battery for a quick fix. The fact that it happened a second time makes me want to have a possible understanding of what I did, and if there's a workaround that doesn't involve me shelling out another 50$ for a new battery.
This is what had happened in the chain of events leading to this (Starting from JB Upgrade):
1) Rooted, and installed a generic Cyanogen mod on my original droid 4 (with Safestrap)
2) Randomly bricked, tried to take out battery without realizing that there were screws holding the flex cable in place.
3) Leaving incriminations out, I attained a second one.
4) Rooted it again using windows utility, and installed Liquidsmooth (Safestrap again)
5) Had the issue again, and bought a factory cable from a vendor in China. Was having a pile of driver issues throughout all this (got a new usb data cable, and used a specific port in the back of my pc that it liked.)
6) Factory cable booted it was able to get it back to normal while it was plugged in. Then swapped the battery the right way, used RSDLite, flashed Stock Rom, and got it working. Several times I've had to reflash.
7) Rooted again, safestrap, then flashed Liquidsmooth again. I had to reflash a few times with safestrap. I am using Rom slot 3 also.
Yesterday I decided to upgrade to the latest version of Liquidsmooth. I did not uninstall the operating system before flashing, and I'm pretty sure I completely ignored the fact the battery was under 1/4th charge.
So aside from all that, this is where I stand:
When using a standard data cable in the favored USB port of my PC, the screen stays blank, but a little green light appears in upper-left corner of the droid.
When using the factory cable in that port it boots, but will not charge. I was able to use AP Fastboot to reflash stock this way. I tried flashing the stock JB ROM with RSDLite initially, and it had an error on stage 6. But I was able to get it using the Windows Utility.
Now the issue is when plugged in the power charger it shows the Motorola logo, disappears, then again non-stop in an endless loop.
I have another charger coming on the way from Amazon (one usb, and one wall one), so that's going to be my next step.
If anyone has any little hidden secret or suggestion that will fix this problem that I am not aware of, please please by all means throw it out there! I would be eternally grateful.

the charge mode is software controlled, if the rom is not correct, battery will not charge

Re: XT894 Charging Issue
Ah, that came to mind. Thanks for clarifying that. That's definitely a good sign.
What actions do you suggest I take to get that part of the phone back to normal again?

try wiping data in android recovery
Hard Reset (Alternate method)- DROID 4 by MOTOROLA - Verizon Wireless Support
if that doesn't fix
reflash stock rom, using .xml file and rsd lite
follow my instructions
How to Use RSD Lite to flash a .XML Stock Rom
also check for Motorola/windows Driver issues

Same issue still
I did the following:
Used RSD Lite, had a successful flash this time using 4.1.2_2.
Took it off factory cable (which always immediately powers off on removal, is this normal?)
Tried booting it off power, no go.
Plugged it into the charger, same issue.
Tried factory reset, couldn't get it passed the Android Andy.
After that, I tried flashing the 4.1.2_1 xml.
Had a successful flash.
Tried to get in recovery, and held both volume buttons. Didn't work.
Then I went into security settings and did a full wipe. Still didn't change anything.
Flashed same rom again, and then was able to get passed Android Andy by holding both volume buttons unlike last time where it was unresponsive.
I wiped the cache, and chose factory reset.
Powered it up again, and still had the same issue.
To clarify a bit on the factory cable: I've used it on 2 separate xt894s. Both devices always powered off on removal even on ones that were working fine. As I asked above: is that normal?
To recap again: it's showing the red circle with the M when plugged into the adapter. Then the screen goes blank. Then while the droid is in the charger, and I tap the power it up again it shows that, goes blank, and again in a non-stop loop. I've also tried holding the top button down as well with no different results.
The battery feels cold (I have air conditioning on), and when it's not plugged into anything the phone pretty much acts as if it is bricked. No red flashing light is shown on charger either, in fact no LED is lit up at all. The red blinking LED only shows on factory cable. I've tried two separate outlets in the room I'm currently in which power up other devices, and that's a no go.
The last time I bricked this phone didn't have that charger. Instead it had a USB charger with the adapter (was the default Verizon one). That one had the same results as the USB data cable I'm using now (a green light that did not flash). I had the battery completely removed, and the factory cable did the same thing as it's doing now.
Also around the time that this happened in Liquidsmooth, the icon showed that the power was charging (but the battery kept getting lower which makes me feel skeptical). Several days ago I left it in the charger for roughly two days as well.
I only have charged this phone with this current AC charger after the brick (I would link it, but the forum claims I don't have 10 posts). It does state that it is legitimately for XT894.
I'm going to leave it in that one for a few hours, and see if anything different happens. I never was able to get the M logo last time which is the big difference.
I ordered a second factory cable just to see what happens then.
Anyhow, does this seem more like a dead battery after my results, or is there another option I can try software wise? Or am I doing something incorrectly?

[Bug] Phone crashes during loading

I do not even have my S4 mini for two weeks, and I've allready problems with bugs
The problem is that sometimes (tonight it happened the second time), when my phone charges overnight (~7-8 hrs.), at the morning the LED lights green, and the phone does not respond to anything. I've tried to press every button, the emergency power off combination, wait for 10 mins... but the LED is still green and nothing happens.
After taking out the battery it works again.
Only thing I did was taking out the Battery in order to be able to take out my SD-Card and copying some music to it.
Is anybody else facing this issue too?
PS: I haven't installed the latest firmware update, since I always wait 1-2 weeks before I install it

Lets check a few things first:
1. It's the S5 mini forum, so I assume you have one and not S4 mini;
2. Are the battery, charger and USB cable originals? If not, try different one, Samsung preferably;
3. Did you try removing the SD and/or SIMs for charging?
I would update the firmware as it may fix the bug that may cause the problem, if system related. To make sure it's not hardware, back up your days and do a factory reset, and if you are not on stock firmware then revert to stock first.

1. Yes, I do have a S5 mini now, my old S4 mini has died (hardware)
2. I mostly use the orginal charger or the one of my S4 mini. But yesterday, when it happened again, I'm 100% sure that I used the S5 mini charger
3. I will try this tonight
As I found out after my first post, this does not only happen during loading, but also when just having the screen off in your bag.
Upgraded Firmware yesterday, my brother plugged it in (I don't know which charger he used), and BOOM it happened AGAIN. Just like one day before I took out the battery, this time to copy maps to my extSDCard. And later, when sitting in the sun, it happened again, the battery was warm but not hot (I have an App that calles my at 41°C, but it seems like this has not been reached and the phone also didn't powered off when it had 44°C)
I will try to charce without SIM and SD-Card today, even if I don't think that it'll change anything.
PS: The emergency power off seems to work, I probably just waited not long enough

Note 4 from ebay: sometimes doesn't recognise charger/won't boot ; mmc_read failed

So i bought this note 4 off ebay. My other note 4 is busted (screen popping out, turns on and off) and i didn't want all the stuff i had for it to go to waste, i have a newer S8 too but i need a spare phone.
And off the box it would not turn on! This was fine you know because i was used to my old note 4 needing to be perpetually charging to stay on. That's just how it is i guess.
But to my surprise the real issue came up.... It wouldn't recognise charging! I put its battery on my old phone it had like 78% charge and was able to charge. I tried my old battery on it and it also wouldn't charge or turn on. So... i took the phone to a shop and was turned away cause they gave up and the other offered to replace the charging port for $150AUD then $120AUD (seemed like a an obvious scam).
They were able to boot the phone! Just from messing around with the battery more. And it seems if the phone is able to boot it can charge. I also did rigorous tests at a local food court like fingerprint, nfc tap and pay and flash photography is fine. However.... even though it was plugged into a power bank and was at 70% battery the phone died... And guess what it wouldn't boot and it wouldn't charge again.
I took it home.... My friend lent me his note 4 on the way with a newer battery. Over the night i got down a method of mitigating the issue... It seems the phone has an inability to initiate the battery to charge when it dies. By that i mean 100% of the time if i can replicate the issue by letting the battery die from there it won't charge the battery or boot. So the most reliable way to restart it is that you need another note to initiate the battery any note 4 even my busted Note 4 would do and you charge it for like 5 seconds then you plug that battery onto this note 4. I made an imgur post about it imgur.com/a/wxVj4AE
This makes sense of why the phone booted at the repair shops as i had initiated the phone on my old phone on the way back by chance. The weird screen also confuses me. Odin i recognise as custom rom thing perhaps it was previously rooted then improperly installed with stock samsung rom.
30% of the time there is this bootloader screen that comes up. "Could not do normal boot", "ddi: mmc_read failed", "Odin mode (high speed)", "system status: custom". The appearance of odin mode and system status = custom leads me to the idea that this once was rooted then rooted back to stock android. With further research i have also discovered that "ddi: mmc_read failed" is a system wide issue which i can maybe fix by 1) re-flashing with stock android and hope that fixes it 2) sending it to samsung to repair or replace for like $70 US 3) have some app to keep it awake almost all of the time in some form.
However i haven't seen this mmc issue be connected with ignoring chargers and not booting.

Soft bricked with charging issue. Need help.

What a nightmare. A friend asked if I could try to fix the a T813 which was stuck on the Samsung logo. The reason it ended up like that wasn't clear but I now believe it must have corrupted the firmware because of a battery issue. I am not sure.
Anyway I assumed a reflash would solve everything, but I encountered a number of problems and now I believed it's nearly bricked.
The battery initially charged but the tablet would not turn off. So it ended up staying stuck on the Samsung logo till it discharged. I tried to charge it again when I was going to begin flashing and it wouldn't. I thought maybe the battery had died so I replaced it.
The battery came with 50% charge and seemed fine. I tried to begin flashing and it had some issues to begin with, stuck on initialisation, then it got half way through and decided to fail. Nightmare
Now it comes up with the blue screen saying software failed blah blah blah use Smart Switch to repair and I was able to get into download mode.
However Smart Switch doesn't recognise the device.
I wanted to attempt more firmware flashes but the battery died. Now it will not charge.
It loads the screen and turns off. I have no way of knowing if its charging at all.
Does the battery need software to charge? Or do I have a charger problem? I know if the battery had charge it would only be soft bricked and I could continue to try and fix it, but until I can work out why it won't charge. It essentially bricked.
It might be important to add that the only thing I have to charge this tablet is a s9 phone cable and charger brick which is 5v 2a I think. Is that enough? Because of this the tablet turns on the screen and uses the power its gained showing me the blue screen. I am wondering if I am fighting a battle between drain and charge. Anyone got any advice on what I can do?
