So last night I had booted into fastboot mode and was going to boot into recovery (TWRP) and I fell asleep while I was on the fastboot menu. The battery was already pretty low so I assume it just died from there. I put it on the charger today and it's blinking the charging batter logo on and off. It won't charge. I am still able to (while on the charger) boot it into fastboot mode so I flashed factory images, but that hasn't done anything different. So it's just sitting here on the charger flashing the battery with the lightning bolt. I've tried all combinations of holding the power button down but it will vibrate, show "Google" on screen for a second, then go back to the battery logo. I've tried powering down from fastboot, but it does the same thing. It won't boot into recovery either. Suggestions?

My phone is rooted with stock rom. The only changes are listed below
Froze bloat that was safe
changed bootanimation to stock samsung
replaced some apps with inverted versions of themselves (ex. google +, stock messaging)
Here goes:
I was using navigation and I noticed that my phone was off after I had finished. Nothing worked at all, I could not boot into recovery or download. I connected the phone to a charger and red led flashes and an empty battery appears. The battery was full. I could reboot the phone while on the charger, but it would shut off as soon as it got to the homescreen. While off, If I pressed the home button, the green battery would appear as if it were charging. From here I could boot into recovery and download mode. The phone will only boot into these modes while connected to the charger. Here is where it went bad. I attempted to restore a backup while the phone was on the car charger and my car charger got pulled out in the middle of a restore. No charger meant that the phone shut off mid restore. Now, when I plug in the phone, the red led appears and the empty battery with a circle inside appears and then goes away. This repeats itself over and over and the phone buzzes when the empty battery reappears. I can still boot into download mode but not recovery. If I try to flash the stock samsung rom via odin, it says that it passes, however upon automatic reboot the samsung appears and nothing else. After the samsung appears the phone just continues to buzz every 5 seconds or so as if it is trying to do something. Could it be a bootloop? I have done a ton of searching here and now I am resorting to help! Your time is appreciated and beers on me if you can help me get my phone back to normal.
What Rom/kernel were you using before this happened? If custom, which one?
I have another thread a few posts down with the same topic. I am going to delete this one. I was stock rom and kernel. For some reason the phone will not recognize the battery. I tried a new one at verizon and the same thing. I can now boot into both recovery and download mode when connected to the charger , but the phone shuts off as soon as it boots and shows an empty battery with a circle in the middle. Sometimes it does not make it through the verizon boot animation and sometimes it makes it all the way to the homescreen and I can make a few selections before it turns off. After flashing the stock kernel and rom in odin I believe i am completely stock, however I do not want to chance sending the phone into Verizon. I believe that I saw a thread before this happened to me talking about having to calibrate the battery in some way and it had an item to flash in order to fix the problem. I can not find it now. Any ideas? Now that I can access recovery is there anything else that can be done? Why won't the phone recognize that it has a battery? As soon as I pull it off the charger it shuts off. When it is on the charger it appears to be charging and the green in the battery appears to be at about 80% but the level does not move up or down at all. Thank you for your help ahead of time.
what am I supposed to do in this instance?

Ok when I leave it there to charge after about 5 minutes it tries to boot up again on its own... its like a boot loop but it stays turned off for about 5 mins in between.
Now I believe its officially stuck at the CM logo screen after the data only back up and restore. It stopped turning off which I think was due to battery and when I plugged it into the PC it turned on and has been at the CM logo screen for about an hour now.
It also refuses to boot into recovery now. Stock or Open Recovery. It only shows the green charging LED and when I do a force shut down it blinks on and back on in about 1 second. I have no clue what the deal is. I'm going to try and flash a stock image with RSD Lite and try it all again.

Your battery is empty. You can't flash anything via fastboot in such state.
When the battery is empty while starting the phone, the bootloader charges it a bit first (that green LED). Only when the battery is charged a little, it switches to boot.
What you want to do is to catch the moment when it starts to boot and hold the volume-up to get to OpenRecovery. OR supports charging so you can let the battery charge more there.

Thank you again for your responses.
I was thinking along those lines... But it seems like as soon as it gets a charge that it goes right into the boot logo. There doesn't seem to be any middle ground to go to any recovery mode. I was stuck in a similar situation before but it wasn't constantly trying to boot.
Here is what happened:
When I flashed data only, I selected "reboot after" option so it is constantly trying to do that re-boot but since it cant boot it stays at the CM logo I guess until the phone dies. Then it charges for a while with the green LED and then it tries to boot again. I have tried to access all kinds of recovery and fastboot and everything at the usual intervals and I cant get it to start any recovery mode because it is still following the re-boot command from Open Recovery.
I will keep trying but this time seems different than when I had low battery/no recovery in the past instances. Something is overriding my recovery and I think it has to do with the Open Recovery reboot after flashing command.... I even opened up the back of the phone and disconnected the battery and its still not working.

I got fastboot working by plugging the phone into a dedicated AC power charger, not one with a USB adapter. Then I let it sit on the boot screen for a couple hours. This way it fully charged the battery and I could bring up fastboot.
What was happening with the USB adapter was that it would try to boot, die, and refuse to go to fastboot, over and over again. I would not have got it working without a dedicated AC power charger.
That literally happened to me a few days ago. Fastboot will say a warning on the screen, somewhere around the middle, "Battery Low" or something along those lines, I paid it no attention, as I knew it was plugged in and should've been charging through my processes. Well, the battery has to be at least 50%+ charged before fastboot will allow any connectivity or communication with ADB or Fastboot on pc. Facepalm.
Always double check battery charge at least 60% or more to be in the safe side, or you risk to soft-brick to even hard-brick your phone.
Hello guys, hope someone could help me.
I have a Moto G that has a bootloop, I cannot get into bootloader menu either. I've tried combinations that worked for me previously (Power + Vol Down, Power + Vol Up + Vol Down) in different time intervals (Up to 2 minutes) and when I release the buttons the screen blinks and it starts again with the looping, like it tries to enter and fails. When I plug the charger it shows the battery logo and 0% and it loops in that screen too, it just won't charge. I was able to charge the battery externally and it's still bootlooping and no bootloader menu. What could have happened? I didn't install anything new, the last thing I did was plugged it with a car charger it was like 20% and it restarted and started looping. I've tried everything I could find on the Internet but I couldn't find someone with my same problem. Please help.
I completely drained a OnePlus 6 (6 gb) running Lineage OS 18.1 with Magisk root. When I plugged it into the OnePlus charger that came in the box, it started to boot loop, showing the 1+ logo, the unlocked bootloader warning, then "Battery is too low" warning (red text, different languages), then shutting off to repeat that. Sometimes it would not do the "Battery is too low" warning.
I've left it to charge for 2 hours now with no luck. After a while it stops boot looping then just stays black. When I click the power button once it shows a charging screen, a circle with a lightning symbol and shows a charge going into the circle.
It does not boot when not plugged in.
When I try to boot it and it goes onto the 1+ logo screen or any screen, then I unplug it, the screen will completely turn off.
I've tried to access fastboot mode and change chargers but both don't work. Holding the volume button and power button just starts the boot loop from a black screen.
Is there anything I can do to fix this problem? Or another forum that might have a solution? Thank you.
Edit:
I am able to get it into fastboot mode, but I cannot boot into twrp through "fastboot boot" or from the recovery mode option.
When I use "fastboot getvar battery-voltage" I get either 4329 or 1802.
This phone is used by my mother, she said first is cannot be charged, then the phone low battery shutdown.
I replaced the USB-c port and change the new battery, what happens when I try to boot in the list:
When I try to power on, the phone just shows the logo than shutting down.
When I try to connect to the computer, the phone screen just has an animation of flesh charging and an orange light.
The phone can go into fastboot mode but not recovery mode.
So what should I do to save this phone? or just let it go?
