Hello Everyone,
I am using Samsung Galaxy TAB A6 (SM-T285). I tried to install a new ROM. I wiped the system and tried to install the ROM but it didn't install. I rebooted to find that it was stuck on reboot. Not switching on or off. Not recognized in computer. Just one screen for nearly 3 hours. Find the image
Kindly help me at the earliest.
Not switching on or off? Hold power for 10 seconds, longer if necessary, and as soon as it dies, press vol+ until you see anything different?
Hi @Mr.Pachacouti,
Thanks for your reply. I tried pressing several combinations such as power + vol up + home, power + vol up + vol down but nothing worked.
Fortunately, my Tab ran out of charge and it is switched off.
What should I do next ?
Thank you for your help in advance!

Hi,
I flashed TWRP and CM 10.1 but then I got problems with the phone not charging (still having that issue but will post it in another thread). Anyhow I decided to reflash the the stock rom and during the flash the phone randomly restarted. Luckily for me I was able to boot up and everything is working fine. the only problem is i can now longer access my system recovery (power and vol down) or fastboot mode (power and vol up). When trying power and vol down the phone starts up as normal. when trying power and vol up the phone vibrates, the bottom 3 keys light up and then nothing. I have to then hold down the power button to turn the phone off and back on. I hope someone can help me troubleshoot this as I have no idea what to do.
Many Thanks!

Recovery is accessed by volume up, volume down, and power held down simultaneously for approximately 10 seconds or until you see recovery. Not sure about fastboot. Have you tried to see if your in fastboot by using adb and checking for fastboot devices. You may be getting fastboot mode. I forget if it actually said anything on the screen. Good luck!

sorry was wrong.
try turn phone off, add usb, then press volume up. I think that's it.
Hi
did no work also
I am having the same problem, went to lg service centre, they could not enter download mode as well. I might need to change the circuit board for $321 singapore dollars..
Hi
i think you have to use this fix: http://forum.xda-developers.com/showthread.php?t=2582142
This happened to me,
Try holding the power and volume down hold until lg logo, let go and press and hold the volume down and power again, it should get you in recovery.
It might get you into a screen called "Factory hard reset" Agree using the power button, and it should take you to your recovery, and try flashing a ROM along with the Gapps (if you want, which I did) and then I used a recovery file after booting back into recovery to restore it to my previous state.
Good luck :good:
Shut down phone
From what I got from this, you're having problems shutting down your phone, correct? It keeps booting back up after the screen goes black? If this is the case, hold the power button (and don't let go) until it goes black, reboots itself, then goes black again. Shouldn't take more than 2 seconds after rebooting to shut down. Then, you can do volume up + USB to get into download mode.

Thanks for your help,it sorted out my problem! :good:
Recently tried to flash a new bootloader and modem in my S7 Edge through Odin, but now the screen is stuck in the Powered By Android initial boot screen. I cannot turn it off by using the power button, the only thing that works is if I press the power button + volume down, however that does not take me to the Download Mode but instead just restarts the phone and back into the Powered By Android screen. Volume Up + Power does not seem to be working.
Am getting desperate now, please help!

Managed to fix it
What I did was keep holding volume down + menu button + power without letting go. It rebooted into the Powered by Android many times but after about 3-5 minutes of holding it straight it finally sent me to the download mode where I was able to install stock S7 Rom.

I recently updated my Samsung Galaxy Tab A T280 to the latest firmware and I lost my root. So this afternoon I re-rooted it. Or I attempted to, anyway. Everything seemingly went fine, and I booted into TWRP just fine. I went to flash the ROM and I also selected wipe cache/davlik cache to be done as well, and tapped reboot. My device then turned off and when it started the reboot, it got stuck on the Samsung Galaxy Tab A logo screen and would not move or power off by holding the power button (I tried for a LONG time by using a rubber band to hold it down so I didn't have to, with no luck), and every other combination of buttons wouldn't do a thing, except for holding power + vol down, which made it turn off and back on, but it wouldn't finish rebooting and it just got stuck at the Samsung Galaxy Tab A logo again. So then I thought that maybe plugging it into a charger might not be a bad idea, and after holding down power + vol down again, it turned off and turned on and showed a battery with a charging symbol. I've had it plugged in for an hour and it does not show a charge or do anything except for go back to that boot logo if I unplug it from the charger and again hold down power and volume down separately.
I know it's not hard bricked because it is somewhat responsive so I think there's a chance to fix it, hopefully. I just want it to turn on and fully reboot into anything or in any way that will allow me to be able to fix the issue. My computer will not recognize the device so ADB is not an option right now unless I'm wrong.
Thanks a lot guys, I am so confused and could really use some advice.
What firmware did you install
Try to install original firmware via software "Samsung Smart Switch" on your PC with connected tablet.
I too recommend that you try installing the last firmware that you were on via Odin. Also, when you hit that screen lock issue after a firmware flash, where only the Samsung logo appears do this:
1. press and hold Home + volume up and volume down along with power button (that's all 4 buttons). Hold it there for at least 20 seconds and it should power off.
2. Once the device powers off keep holding the buttons but let go of the volume down button.
3. Once the tablet starts to power back up again release the power button and then in about 1 to 2 second release the rest of the buttons.
This should get you back into recovery. You should at least be able to restore any backup, that you should have already, on your external micro SD.
Good luck.. : )
"Chance Favors the Prepared"
the above post is 100% right. Reboot back into recovery and you'll be good to go. Also twrp has a option to reboot back to recovery so this doesn't happen, just a fyi for future knowledge. Best of luck..
You tried to flash a rom with twrp?
You need to flash stock firmware with odin.
Attempted to flash
[ROM][11.0][UNOFFICIAL] Nexus Stock for 2019 Galaxy Tab A 10.1 [SM-T510]
using TWRP and it rebooted to the G but wouldn't load.... restart and now I'm in a FOREVER bootloop:
Ideas? I've tried holding Power + Vol Up, Power + Vol Dwn, Power+Vol Up+Vol Dwn, connecting to computer for adb which doesnt see any devices so I can't force into recovery... ANY help would be great!
Can you go in the Download Mode?
Nope.... I actually got it fixed LOL.... I had to remove the back, disconnect the battery... hold the vol + and vol - plug battery back in and then attach to computer to power on... THAT put me in download mode to fix..... but trying it without disconnecting the battery... it wouldn't shut down, I could hold the power button for a week and it just kept going through the loop
