I've tried to put a new ROM using Clockwork Recovery 6.0.1.2, during process it stuck for 4 hours and was turned off by power button.
After that tab don't react on power button, on pwr+vol up, pwr+vol down, pwr+ both vol buttons, nothing.
It even doesn't show battery icon when charging - screen is always black.
Any advices?
Thanks in advance.
I think the method described here will do the trick: http://forum.xda-developers.com/showthread.php?t=1478361
kallt_kaffe is having the same problem and he describes the procedure as: "basically tape down the power button to force a reboot cycle."

1. Put on your computer headphones and turn the volume up.
2. Plug your tablet into your computer via USB.
3. Hold the power button & Vol - keys together (Volume - is the side that is closest to the power button)
4. Listen for the "USB device connected" or "USB device disconnected" sound on your PC
5. If you can hear that, something has gone bad within the bootloader and the display does not initialize properly. Edit: The ICS installation does indeed attempt to patch the bootloader
6. If there is no sound, then the tablet is stuck in limbo, so go ahead and do the battery drain procedure as described in the above post.
7. If, however, your computer detects a device connecting and makes the sound, you can most likely still enter Download mode. You will have to do it blindfolded though:
-open ODIN 1.85 and see if it shows a connected device. If your PC made a connected sound, then there will most likely be a yellow COM port in ODIN.
- Hold [Power] & [Volume Down] together for 15 seconds or longer whilst monitoring your Device Manager windows to see if you can get the tablet out of APX mode and have it appear as another type of Device. Then press Volume+ several times with 1.5 sec. intervals. With luck, this should get you into Download mode, and ODIN will shine yellow for you.
- While doing all of the above keep your headphones on and listen for connected or disconnected sounds from your PC.
- Make sure you have this firmware for the P7300 which contains a bootloader, which is essential: http://www.hotfile.com/dl/162686792/c693269/P7300ZSKK2_P7300ZZHKK2_TGY.zip.html
- Flash with "Bootloader update" checked in ODIN and see if device is resuscitated. If the tablet boots, it will be in Hong-Kongish, but just select a language you recognize from the dropdown, it has them all.
- It may be a good idea to also throw in a .pit file and check Repartiton
N.B. The firmware link that I have provided is for the Tab 8.9 3G P7300 only! Do not flash it on another version of the 8.9!
You will need to search for a firmware that contains a bootloader.bin.md5 file for your tablet model.
Again, all of this will only be possible if the device registers with your PC on connecting the USB cable.

Ok, I've disassembled the device, and removed a battery connector for a time.
Didn't help though.
When I'm connecting tab to PC and holding pwr+vol_down, I hear that connect-disconnect sound and there is a device called
NVIDIA USB Boot-recovery driver for Mobile devices blinking in Device Manager with those sounds.
Odin shows no yellow com, all are empty, so download mode is not available.
you are stuck in APX mode , First go to this link and follow the instructions : http://forum.xda-developers.com/showthread.php?t=1130574]
if you get this in nvflash :
Nvflash started
rcm version 0X4
Command send failed (usb write failed)
this means your device is locked and the battery draining is that last thing that might work for you .
i still didn't try it, but i only disconnected the battery and connect it again but my device still dead for a month now .

is it possible, that some Samsung Service Center will help me? I think that what I did voids the warranty, but anyway, I'm in Ukraine and getting official support here is almost mission impossible.

unfortunately the sbk (secure boot key) for locked Samsung devices is unknown and i was hoping that someone will be able to provide it since it's now increasing problem for 8.9 and 10.1 tabs especially after ics update . actually this is well known mode(apx) with all Nvidia Tegra devices such as acer a100 tablet and asus transformer ee pad but developers there were able to find the sbk for these devices .
if you are covered by warranty and the battery drain method didn't solve the problem you should go to Samsung and good luck . i am not covered by warranty and the only solution i found after connecting Samsung here in Egypt is replacing the mainboard costing almost as a new device (even Samsung couldn't fix it) .

Sounds like they want to get your cash.
If things went to sh*t software-wise, they can be fixed the same way.
They could just UART into the board and restore the bootloader. I don't have to expertise to do it, but they should have it.

1-7 okay. And device is "NVIDIA USB Boot-recovery driver for Mobile devices", not APX (because i installed special driver).
But nothing happend when i try to enter Download mode.
USB Disconnect > Connect > Pressing power and vol button for ~7 seconds (why 15+?.. So 15 i tried too) > Sound > Pressing V+ 10 times... Nothing glows in Odin.

I had a broken bootloader and my display was dead the same way all of youse with bricked tabs describe.
It appears that in your case the bootloader is so badly messed up, that a fail-safe kicks in and sends the tab into APX mode directly.
Consider disassembling your device to disconnect the battery, press Power a few times with ti disconnected and keep it disconnected for a minute or so to force discharge of all capacitors, then reconnecting and attempting a reboot.
Disassembly is really easy - get a plastic knife and stick it under the display near the charging port and work your way around the whole unit. The entire display comes out of the back cover. Flip the display around and there you will notice where the battery connects to the main board, unplug the connector.
Have you tried?
And wut i must do after that?

Disassemble, disconnect battery, press power, short + and - (on device, not on battery lol)... After that connect battery and connect via usb ... the same. cant enter download menu.(

Hi, may I know what new ROM did you flash? And your previous ROM before flashing. So that we can all avoid that ROM until somebody can fix this mess cause by brickbug. Thanks.
Nah. Samsung service sucks.
They said that motherboard should be replaced.
I don't understand how software problem couldn't be fixed w/o hardware replacement.
Screw that, I'll go get Nexus 7.

Hey everyone,
I apologise if this has been asked many times before; but I need some assistance with my HTC one M7.
I was using the phone with low battery - with power saver turned on, it turned off completely after a few moments.
I have put the phone on charge, but the LED indicator is not showing up nor the phone turning on or charging at all.
I went through forums, and tried the power button + volume down button to bring up the boot menu, this menu did actually appear - but me being the fool I am - I selected the power down option.
I have been unable to bring the menu up again with the power + volume button combination.
I then connected the phone to my PC - where its installs a driver - qhsusb_dload. I have tried the power + volume button combination with it being connected to my PC - where I hear the device detected bing and device disconnected bing while I hold these buttons down, still unable to charge/power on/ or bring up the boot menu.
I have also left the phone on wall charger for over 12 overs again to no avail.
Can anyone provide any advice - or any method I can salvage the data stored on it i.e. photos?
Thanks for reading - appreciate any help!

If you get it to go into that boot menu again. You sometimes have to hold the power and volume down for about 15 seconds, then release them and again start holding the volume down. This is something I had to do to get into recovery back when my bootloader was still locked.
The power may not coming on, but if you are getting usb sounds from plugging it in maybe the computer you are connecting to could be switched.
I had hard times connecting before from certain machines cause they wanted to run an HTC Sync program. You could try a different machine.
Often people say regarding the behavior of the 3.0 vs 2.0 USB ports, that it is 2.0 that will work. And you might try a Vista machine to get fastboot working.

qhsusb_dload is a well known issue, not caused by the computer you are coonecting to. Its can be caused by a bad firmware flash (flashing an incompatible firmware.zip) or because of an hardware failure. Easy to know what is the cause. Did the phone randomly went in qhsusb_dload mode? Yes ---> Hardware,will most likely need a motherboard replacement. Did the phone went in qhsusb_dload directly after flashing something? Yes ---> Software problem can be fixed with the unbrick project.
So I have been looking for weeks and I have not found a single person with the same problem as I do. Let's start off by saying what's wrong with it. I was on my phone, using it as I usually would when all of the sudden, it crashed and went to the Samsung Galaxy S6 boot up screen (It continued to stay like this forever), by the way, my device is NOT rooted. I'm unable to turn the device off manually so I have to wait for the screen to turn off on its own. When the device is off, holding the power button does absolutely nothing. The only way for the device to turn on is for me to plug it in. The two things I'm able to do is perform a stimulated battery pull (Volume up + Power) and get into download mode (Volume down + Power + Home). I cannot get into recovery mode with the device on or off either (Volume up + Power + Home). I've tried Odin and that doesn't work. It passes, but my device just resets and goes back to the boot screen forever. I've tried Samsung Smart Switch, but cannot do that either due to the program crashing every time I confirm my model number and S/N. I was just wondering if there's any other way I can fix my device on my own without getting a replacement. Thanks.

Same fault
Here's a quick reference for how to reboot and reset your 2019 Galaxy Tab A 10.1 (SM-T510/T515) using the hardware buttons:
Force restart:
- If your device is frozen and unresponsive, press and hold the Volume Down + Power keys simultaneously for more than 7 seconds to restart it.
Boot to Recovery Mode:
- Power off the device
- Press and hold the Volume Up + Power keys at the same time.
- Release both keys when you see Recovery Mode.
Boot to Download Mode:
- Disconnect the USB cable
- Power off the device
- Press and hold the Volume Down + Volume Up keys
- Insert the USB cable
Boot to Safe Mode:
- Power off the device
- Press and hold the Power key.
- When the boot logo appears, release the Power key and then press and hold the Volume Down key.
- Continue to hold the Volume Down key until the device finishes restarting.
- Safe Mode will display in the bottom left corner of the screen.
Since there is no Bixby button, these combinations are different than the Galaxy S10. If you know of additional combinations, please contribute to the discussion below and I'll consolidate here.
If there’s no response on your device or you're stuck in a boot loop, then you might need to wait for the battery to drain. The 2019 Galaxy Tab A 10.1 has a non-removable battery pack, so disconnecting that isn't an option. Hopefully, the system reverts to its normal function with a cold boot. This can take time if the battery has high charge left at time of failure. Depending on how fast your battery drains, this can mean waiting for a few hours to several days.
UPDATE: With the right timing, you can break out of a boot loop into Download Mode...but it's tricky:
Insert USB Type C cable connected to your PC
Press and hold the Power and Volume Down keys for exactly 7 seconds (hard reset)
Release the Power key and press and hold both Volume Up & Down keys (enter Download Mode)
If you don't see the blue bootloader unlock warning screen, keep repeating the above two steps
The trick here is that you're trying to time your switch to the Download Mode keys for the exact moment the hard reset takes effect. If you see the boot logo while still holding the first key combination, it's too late. If you switch too early, you won't trigger the hard reset.

Thanks, that was an error in my initial post. I was figuring these out by trial and error, but it turns out that our hard resets are basically the same as for the Galaxy M30, which also uses the Exynos 7904 SoC and has no Bixby key.

Yes, I did the same way

1. Enable OEM Unlock
2. Turn the tablet off and unplug the cable
3. Press and hold both volume up and volume down buttons and plug USB cable to host computer
4. You will get wipe screen. Long press volume up to unlock the bootloader.
Now I have to find matching ROM and patch the boot.img and flash.
I believe you have to disable Vault Keeper to keep root intact.
Brand new out the box 11am this morning.
Opened the parcel cool no damage. Powered up fine, had a mess with it, no problems check the speakers were fine and no issues plugged it on charge to 100% took it off and left it for an hour or so, went back to it and physically used it to use Facebook and play candy crush cool no problems. Took a few photos and no problems again. Put it on the side still on near 90% and went back to it 30 minutes later completely off and won’t turn back on, tried charging it nothing no sign of life, tried rebooting it and still nothing. Please tell me that this is not the end and I need to get a replacement... ?*
