Basically, the device wont turn on no matter what I do, no matter what key combinations I use. If I plug it into a power outlet, the LG logo comes up, then the tablet shuts down, then the LG logo comes up, rinse and repeat.
If I plug it into a PC, I get the sound of it connecting and disconnecting over and over, but nothing comes up on the display.
I've never had a bricked device that I couldn't unbrick by going into adb or download-mode but I can't even get into download mode. I'm stuck and ran out of ideas.
Any help would be greatly appreciated! Thanks!
EDIT: I got it to show the charging logo. Basically just left it plugged in doing the logo-loop for about 15 minutes until the battery indicator showed up. Very strange. Hopefully once it's charged everything will be fine.
Have you pressed the volume up key + pressed the power button multiple times over and over, I can get mine into download mode only if I use that method.
When I corrupted my tablet, first it would hang on the LG logo screen and never boot into anything, once, then I got the issue of it boot looping only into TWRP only even after installing ROM's, then flashed TWRP in TWRP, and wala, fastboot boot loop only, for the life of me I could not get it to go into download mode, I had almost given up, but alas the last attempt to randomly smash buttons unveiled that holding volume up + clicking power over and over rather quickly rendered it to download mode...
If your getting the LG logo screen its likely that you can recover it.
As for the connecting/disconnecting, its likely that the device your connecting it to cant provide the power being pulled by the device, I have to use a powered USB hub for my Alienware 17 (R2) early 2015 laptop, as it cant handle the power draw of almost any devices, I have had issues even with self powered USB portable hard drives, so I really can feel your pain.

Here is the series of events. Upgraded to LG optimus G one week ago and that same day, rooted it and installed Cyanogen 10.1. Week goes by functioning completely normal. Today, the battery was down to 5%. Powered off the phone and hooked it to my PC via micro USB cable. Return an hour later to turn it back on. LQ logo appears for a split second then the screen goes dark though still active because of the backlight. Only response I get is when holding down the power button until the screen goes off. It then powers back up and briefly shows the LG logo and the screen is blank again. No response from any other attempt to boot the phone into recovery mode or normal.
Simultaneous power and volume down does not enter recovery mode, nor does any other combination of keys

Are you holding down the power button while still plugged in? In essentially the exact same scenario you are experiencing, my phone will not turn back on if I have it plugged in.
Unplug it, hold down the button until LG logo appears and release while LG logo still on the screen. That's how I have to do it.

Its not going to charge with the battery that low on the computer. you need to power it off (vol down + power) and plug it into the wall charger. leave it for 30 min. unit should turn on at this point. if not read the repair guide in this thread or jump on the irc and myself or some of the other people can help you.

The USB port I was plugged into was a 3.0 which has extra power sent through it via a bios setting specifically to charge phones. Anyway, I disconnected it and it is now connect to an adaptor from a wall outlet. We'll see what happens in the next 30 min.
Hello everyone, thank you for your time.
TL;DR: Phone boots into download mode up until "Downloading...", recovery mode until "RECOVERY BOOTING," and can only boot right when I put the battery in. The battery is fully charged, and I can boot up until my home screen only once so far. Will a jig fix the issue, or should I try to get the phone replaced by TMobile warranty as I have before?
I have a Galaxy S3 from TMobile, and have been running CyanogenMod for about a year now. 2 days ago I flashed a nightly release, which I assume was unstable. Yesterday, my screen was on and then my phone turned off (low battery, but 99% sure it was a crash rather than a power off), and did not boot up again. After attempting to pull the battery out, charge for hours, turn on and plug in (in different combinations), the furthest I could get was a couple of seconds of the CyanogenMod Galaxy S3 logo initial boot screen (not the rotating splash screen).
I took my phone to TMobile today and was about to get it replaced until I realized I didn't mask the flashes.
The last time I was in an exact same situation with the same phone model, and my flash counter was still showing custom firmware, yet I did manage to get it replaced effortlessly, but I didn't want to risk what was a possible fluke again.
I get home, and here's my current situation.
The only way the phone boots up in any manner is when I take the battery out and the charger is not plugged in. Here are the scenarios I run into:
1. Boots into download mode, can press VOL + to get to the "Downloading..." screen, then shuts off 2 seconds after.
2. Boots into recovery mode, only up until "RECOVERY BOOTING", then shuts off.
3. Boot by pressing power button, plug charger in, shows grey battery icon.
3. Boots into download mode, can press VOL -, either shuts off, OR
3b) Only after tons of tries, it booted up all the way up until my actual home screen, then shut off.
I can't have the charger plugged in while booting (pc or wall), and I can only boot right after I put the battery in.
Are there any suggestions as to what I should do? I was thinking of buying a jig from Amazon, but I don't know if it is hard bricked or not. Should I just attempt to get it replaced under warranty once again, even though it shows the flash count?
Thank you very much!
FIX: STUCK POWER BUTTON PROBLEM
So, one thing I didn't check. Take the battery out of the phone, wait about a minute. If it buzzes as if its powering on, that means that your power button (either the actual button itself or the switch on the mainboard) is stuck.
Solution: Smack the power button with your battery until your battery has a (small) dent. If it doesn't work, smack it a couple more times. Took me 2 tries, second try, phone didn't buzz when I put battery in. I press the power button, works like new. Absolutely....ridiculous
I was getting a notice on boot that said "Your device is corrupted and cannot be trusted," so I held down the power and volume down buttons to get it to fastboot mode. However, I couldn't get it to be recognized in fastboot on my laptop. At one point I selected "reboot bootloader" and the phone promptly shut off, black screen and completely unresponsive.
From that point on, I can't get it to do anything. I've tried holding power + volume down for 20 seconds and then plugging it in (as noted in another thread) as well as taking it apart and disconnecting the battery to see if that would reset it somehow. No dice.
Any other suggestions before I give up? Thanks very much in advance...

my device is for the most part of the time in qualcomm mode, but I managed to have access to the phone 3 days ago, installing apps & stuff, worked perfectly well until I had
the bad idea to try to charge it through the charger instead of charging it through my computer...
how I've done it?
I used the power reboot technic :
1) pressing the power button for 1 minute
2) doing nothing for some seconds
3) pressing the power button again for 1 minute
4) connecting the phone to the charger, the red light flashed
5) the battery icon appeared soon after
6) waiting for complete charge, phone rebooting
it worked once, so I suppose it can work again. fingers crossed.
My Oneplus 3 is currently facing the worst form of boot loop. The phone keeps looping until it drains all of its battery.
This phone has been running like a tank for the last 4 years. When this issue began, it had 75% of the battery at the time. The phones Power button menu got automatically triggered and phone was restarted (all within 5 seconds) and ever since its stuck in a boot loop.
Below is the current scenario
Power off button has no effect, the phone keeps looping since then
Vol+ enters fastboot but I can't select anything, looping continues after 2 secs or so (Device state: LOCKED)
Vol- has the effect that the looping stops as long as I hold the button. After releasing that button the loop pauses for let's say 10secs and the loop continues. Otherwise no effect.
Power & Vol- buttons pressed together leads to a PIN unlock screen after the boot screen, I enter the pin, hit OK and as the Decryption begins.....we are back to boot loop
when plugged to power connection: loop cycle seems to be larger, loop occurs every 10 secs. in between the phone stays off
when the power becomes low, the boot loop continues but with the 'Battery too low' screen and the loops continue until the battery completely drains out
When I hold both the Volume buttons and connect to the PC via USB, the phone establishes a short connection for a few seconds. Not a stable connection, it showed "QHUSB_BULK" port in the device manager and I was able to somehow install the Qualcomm driver.
Post that when I connect, it directly shows a "Qualcomm HS USB QDLoader 9008 (COM5)" in the Device manager but the connection only lasts for a few seconds as the boot loop continues.
The MSM tool detected the connection a couple of times but since the connection only lasted for a few seconds, the tool wasn't able to anything.
I have scoured over the forums for a similar scenario, haven't found any.
Look, the phone has had its fair share of drops and falls over the years and it withstood it all. And this issue happened when I was casually browsing on chrome. I don't know what to say ...Please help!!

Check your power button. I think that it might be stuck in the 'on' position. If you have a case/cover for the phone, remove it and check.
You may also have to open up the phone for checking.
Otherwise, may be a motherboard issue.
Hold the buttons longer.
Try again but don't release until the tool is properly running.

I had the same. The power button broke. He was pressed all the time. Using tape and foil, I changed the contacts with vol + before the new button came.
I am facing the same issue , any solution ?
Update: while I moved on to a new phone, I tried turning on the OP3 once again after 8 months and miraculously the boot loop had somehow stopped and it let me enter the fastboot recovery manager. But my power button is still not functioning so couldn't do much in there.
So while in fastboot mode I connected my phone to the computer and via ADB did a "fastboot reboot" which restarted my phone normally.
Right now..
Power button is dead, so a virtual power button is used, the alert slider is also dead for some reason, so a virtual volume controller.
Whenever my phone shuts down due to empty battery juice or another unknown cause I have to restart it via the ADB fastboot method mentioned above. Other than that the phone works fine.
So this morning my Razer Phone was all fine until it suddenly vibrates twice then the screen goes blank while in my pocket. I once thought it was just ran out of battery so i left it charging for a moment. When i tried to turn it back on, the phone only vibrates once and the screen turns on but appears blank. Even the razer boot logo doesn't shows up. After few seconds the phone comes back turned off.
The charging port is fine so are the charging cable and the adapter. Power button, fingerprint, volume button are all working normally. I also can feel a little heat on the phone while charging just like usual. I think the hardware seems to be just fine. I've tried to get into the recovery mode by holding down power and volume up button for 7-15 seconds but didn't work. It only brings it into the 'blank screen' again like when i'm trying to boot it up before.
I don't know how could this happened all of sudden, i never did anything fancy to it apart from playing games, using apps and such.
Any help would be appreciated.
There maybe two reasons there is a bug with you droid or apps & services running tho or an app or a mod you installed corrupted your systen
did it reboot in recovery or fastboot
u can try to boot to bootloader on PC , turn off your phone then plug in PC by cable, hold volume down + power button to boot to bootloader .
