After replacing the battery my phone stopped working. To be exact the phone shows the following behaviour.
I press the power button and everything goes fine until the phone boots into android. Then a message appears saying that the device will shut off and as you can easily guess the phone shuts off. This is the same message as the one appearing when the battery is low.

I removed the new battery and installed again the previous but the exact same thing happens.
If I connect a charger cable or on my computer the phone starts booting but this time everything goes super slow. When it boots into android, this time the phone does not shut off after the popup message but reboots again. And as long as the usb cable stays connected the same thing occurs again and again. Tried entering recovery/download mode without success.
The huge problem with that situation is not the phone itself but the data that I have not backed up yet.
Any help is welcome.
My phone is an lg g2 d802 running stock 4.4.2 rom, unrooted.

When I try to start the phone, it vibrates briefly, but does not switch on. I tried to remove the battery and try afterwards, but didn't work. Vol Up / Down + Home + Power didn't work.
If I leave it untouched for 10 minutes, finally starts, but this thing is disturbing. The phone has root, I want to unroot and send it in warranty service.
Solutions?

are you sure you still have battery?
otherwise, with the phone shut down, try to connect to PC USB and see what happens.

try starting with Volume Up/Down + Power or VolumeUp+Down+Power.
do you remember installing something before (that needed a reboot), or similar?
Finely, the phone switched on, I reset the counters with Triangle Away, I did unroot complete from the SuperSu, but now appears in Download Mode Knox Warranty Void: 0x1.

I've probably used the LG Flash Tool 10 times the past week on both my home and work computer with no problems. Last night I flashed the KK bootloader and a stock 5.0.2 ROM (after tot'ing back to 4.4.2, rooting, etc).
It hangs at the LG logo and that's where I'm stuck. I tried going into Download Mode, but suddenly both of my computers won't see the phone and give me an error in Device Manager. I've tried uninstalling / reinstalling the drivers as well. Why in the world would that happen unless somehow Download Mode was corrupted, possibly? But it goes into Download Mode fine, and appears to look right...
I've tried getting into recovery but can't. When it should load up TWRP (after telling the G2's "stock" recovery screen I do want to reset), I get the green spinning Android (not the red exclamation) for a second, then it tries to boot up.

Any advice would be appreciated as I've never run into this before.
So when the green Android popped up, I tried to hit a combination of the volume and power keys and WAS able to get into recovery. Unfortunately, it appears, somehow, TWRP was overwritten by the stock recovery. I have no idea how that could've happened. Or does stock recovery technically stay in place since this is "loki'd" and not actually unlocked? And if so, is there some way to get back to TWRP that I'm unaware of?
To add to the weirdness, when I plug it in to charge, it doesn't pull up the battery like it usually does when powered off, it just tries to boot up again...
If I could just get the computers to recognize it again...
Installing the LG PC Suite got my drivers to a point where it could recognize it while in Download Mode. MTP still didn't work, but that didn't matter for Download Mode. Not sure what happened, but at least I was able to flash it back again.
My device will only boot up when it is connected to a power source and after a few minutes of being plugged up it will stop charging and turn on
I recently flashed my device and after flashing, the touch screen will not work.
I have been trying to fix it for a while but I think the problem is i cannot get it to charge at all, so if anyone knows how to make it charge without booting up, please let me know and what i am trying to do is use fastboot to flash another rom that works on my device but i can't because it says Low Battery is this why?

try
Booting from AP fastboot to charging mode
If the Device will only boot to AP Fastboot and it says Battery Low
Connect the phone/Device ato a Wall Charger (not PC)
-In AP Fastboot Mode hold Volume down& power buttons at the same time for +10 seconds
- When screen goes black...release power button
-Then IMMEDIATELY press and hold Vol - and Vol+ to boot to Boot Menu.
- In Boot Menu scroll down with volume down to BP Tools, press volume up to select
- Device should boot to Charging Mode with battery icon
- Once battery is charged, try flashing in AP Fastboot again
This will only work if battery charging Firmware is still preset and not corrupted
If Motorola Device will not boot to Charging Mode, a Fastboot cable will be needed.

Dear crowd, I need support with my Samsung Galaxy Tab S5e/SM T-725 (it is my first Samsung device).
I unlocked it and tried flashing it (with Odin3). This was not successful and now I do not manage to get the device to boot into the Download Mode anymore.
The device does not switch on anymore - only with charging cable connected. In this case it turns on and off eternally showing the below screenshot.
Connecting a USB-C cable while pressing combinations of Power+ any volume key combination does not lead to any result. Only pressing Power+VolumeUp+VolumeDown brings is for a little moment to the screen where I chose to unlock the device, bot after one secons it turns off again being in bootloop subsequently.
SmartSwitch as indicated on the screenshot below does not do anything as the device is constantly turning off again.
Does anyone have a clue how to convince the device to finally allow me flashing TWRP and a custom ROM in this situation?
Advice is more than welcome!.

This warning screen is still download mode. Try flash stock rom via Odin.
Chosse exact firmware, when start flashing you will see the white bar below that text.
Unfortunately, it does not work as the device switches off too quickly. Odin3 then just reports failure.
I wonder if there is a way to prevent the device from switching off so quickly.

so sorry, mine stuck at warning sreen so i can easy flash back.
If your tab fast switches off then maybe it got bootloader damaged, you need research flash by Qualcomn flash tool like QFIL, flashsing for Qualcomn chipset device when it in QDLoader 9008 mode.
After unlocking bootloader I attempted to flash TWRP onto the T510, but now I have managed to soft brick it. Smart Switch did initially connect to the device, but no longer does so, even after reinstalling the device driver from within Smart Switch.
The tablet is now stuck on the screen "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software". The emergency recovery doesn't work as Smart Switch will not connect to the device, although when I plug the tablet into my PC I can hear the sound Windows makes when it detects a new device...
I can't power the tablet off either, not even holding the power button down for 5 seconds, 10 seconds, even 30 seconds does absolutely nothing. Have I properly bricked this?

I had to let my device just drain the battery before being able to boot up into recovery, maybe just let it go flat and try again

I left it overnight to drain the battery. When I woke up the screen was off, yet as soon as I plugged it into my desktop to try again with Smart Switch, it goes straight to the "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software", like in the last pic in my previous post.
Smart Switch still does not recognize the device and it is in exactly the same state as it was before - I can't do anything with it.

Have you tried booting it into safe mode and resetting it from there?
