So I was trying to install Marshmallow on my SM-T800 and got stuck on the Samsung splash screen. When trying to get back to recovery mode I accidentally booted into download mode. I exited download mode but now the tablet is stuck displaying the battery charging image, even when unplugged, and I cannot get it to boot.
Any ideas? Should I just leave it alone for a few days to let the battery drain and then try booting again?

Have you tried all the key combinations?
Do you have a USB JIG?
I'm not sure how installing a rom has affected the bootloader as that's pretty much impossible.
Regardless of what's on screen now, hold POWER + HOME + VOL DOWN until download mode appears.
If still no response you may have to wait until the batter dies.
So earlier today I plugged in my charger into the phone, and it gave me an error messaging saying something about the cable being damaged, and System UI crashed. I unplugged it and made a mental note to buy another charger.
The device was having some issues with SystemUI properly rebooting, so I restarted the phone and got caught into a boot loop.
The device will not go past the HTC splash screen, just rebooting every few seconds.
It doesn't reboot when I go into the white screen bootloader, nor does ADB or fastboot oem detect it.
If I select download or recovery mode, one of two things happens:
1) It displays the monochromatic HTC logo for a few seconds and then reboots back into the normal bootloop.
2) It stays in the monochromatic HTC logo without doing anything else.
ADB does not work in any state, nor does trying to flash an RUU.
I've tried sticking an RUU with an SD Card and going into download mode, but nothing happens.
The device was running Leedroid at the time.
The bootloader is unlocked, and it is S-ON. It is a T-Mobile device with the Marshmallow Firmware installed.
I would very much appreciate help for this as I've been searching for solutions the entire afternoon.
I don't quite understand how a faulty cable would cause a bootloop but not completely fry the device.
Thanks.

So you can't even get to download mode by holding power+vol down for several seconds?

No, it just brings up the same issue of it getting stuck on the monochrome HTC logo.
no idea as i've never had this happen, but when i've had issues in the past i'd let the battery drain completely, then charge it a little, then try booting to download mode. maybe you could try that? did you have twrp or any custom recovery installed?

I've tried that, and I have the latest TWRP.
hello, I need all help, please!
my htc 10 has bootloop, logo htc with black background and reboots, I have no recovery nor download mode, it does not let me use adb commands, I can not use ruu for low battery, when I load the battery it reaches 1% and it reboots and it returns to bootloop, apart I have the bootloader unlocked
Hey!
My P8000 (running Cm12.1, Twrp) is stuck in a bootloop because of xposed. I know how to fix this, if I could enter recovery, but I can't because my battery is to low. I only can enter the bootloader (where you can choose recovery mode, fastboot mode or Normal boot). But if I choose one of these nothing happens and the screen turns off. If I plug it to the charger it boots and is stuck in the bootloop, and draining the battery.
Anyone an idea how to get my elephone charged?
If a factory reset is necessary, that's no problem, just tell me how to get there!

Hey guys,
I started having this issue randomly start occurring a few hours ago and so basically the phone keeps boot looping. This is not a normal boot loop as I can get into fastboot but it still keeps restarting once I'm in it; as if the power button is stuck. I have tried to power down the phone but couldn't so I just let it drain itself over night. I have tried to charge it and I have noticed that the charging icon is in a sort of loop where it tries to turn on then goes to the warning page of an unlocked bootloader and then boot loops. I have no idea what caused this and I can't follow any of these other solutions as I can't stay in fastboot long enough to use adb.
Edit 1:
Just tried to quickly flash the stock bootloader while simultaneously holding power+down to stay in fastboot but still boot loops. I cannot even toggle through the settings of the fastboot mode and the screen just keeps 'refreshing' every half a second so I can't really do much.
Edit 2:
It has just fixed itself overnight and I am able to boot normally after flashing the magisk_patched boot.img
OS: Android 10 stock
Rooted: Magisk latest
