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.

Hey guys, wondering if this great site can help me out. Just got a phone off of eBay (White HTC Evo 4G) However when I plug the phone into charger(s) it doesn't light up, display any LEDs whatsoever. furthermore if I try to power on the device it does the usual display of the HTC EVO 4G Logo on the whitebackground but then the screen quickly shuts off.
I then try the power+vol up key to access recovery menu. It will finally display the menu BUT THEN quickly the screen shuts off.
I then try hard reset, holding power button + vol down button. Same thing, menu pops up, as soon as it does the screen shuts off.
Connecting via USB cable of course windows does not detect it, it wont even boot up for that matter period via this method. lol. Any suggestions?
Send it back .... fast.
Hello,
I am having an issue with my S 3. It is not booting up as it should. The model is SGH-1747M.
I have tried the following and have had the following results:
1) The phone is non-responsive when attempting to power it on with the power button.
2) If I remove the battery, with the phone not plugged in, and then put the battery back in, the phone begins to power on by itself. It vibrates once and then loads to the Samsung screen and then goes off.
3) If I plug the phone in without the battery, the phone vibrates once and the red charging light comes on but then goes off after a couple seconds.
4) If I plug the phone in without the battery, and then insert the battery as soon as the red light comes on, the charging screen comes on but then the phone goes off after a couple seconds.
5) If I put the battery in with the phone unplugged and hold Volume Down, Power and the Home Button, the phone boots to the screen where you can push up on volume to flash new firmware. If I stay on this screen without pressing anything, the phone turns off after a couple seconds. If I push up on the power button, it goes to the screen with the green android man but then turns off after a couple seconds.
6) If I put the battery in with the phone unplugged and hole Volume Up, Power and Home and then release them on the Samsung screen, blue writing pops up in the top left corner (I couldn’t read quick enough what it says) while still on the Samsung screen and then it loads to a screen saying Samsung Galaxy S III and then the phone turns off.
These problems started when I attempted to connect my phone to my laptop to transfer songs over to it. I connected the phone and the battery was charging, but it wasn’t showing up as connected on my laptop. So, I turned the phone off to restart it but when I went to turn it back on, these issues started.
The phone was rooted and has been for the last 7 months without any changes to the firmware or updates to the firmware in that time period and has not encountered any problems prior. I’m not sure what firmware the phone was on prior to this.
If anyone could offer any assistance with this it would be greatly appreciated.
Thank you in advance.
Hi,
I'm no expert, but it looks like a faulty/stuck power button. It's normal for the phone not to completely boot up when it is powered off and then plugged in to USB. But it is not normal for the phone to reboot itself when in recovery or in Android. That's why I think the power switch might be the cause.
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
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.
I hope I'm posting this in the right place but I'm desperate for help.
My phone, HTC 10, froze and then the screen turned off while I was taking a picture.
The charge should have been around 80%.
Symptoms:
The screen is unresponsive.
Couldn't get the home button/finger print sensor to turn the screen on.
Couldn't get the power button to turn the screen on.
A call to my phone could not reach my number as well.
When plugged in to a wall charger or laptop no indicator light turns on.
When connected to a laptop, the laptop makes that connection noise and a long name with QualComm in it shows up.
Tried Power Button + Volume Up for 10 seconds but didn't get any result.
Side note:
The power button was a little faulty before as well.
You have to squeeze it a certain way to make it work.
I need to somehow restart my phone. Any ideas?

Try to clean all buttons really well, if it keeps failing to boot and the phone is still recognized as Qualcomm it's probably bricked.
Simple explanation of the word bricked :
When the phone doesn't boot, when you can't access the bootloader, download mode or recovery it's bricked!

Strange turn of events: I plugged the phone to my laptop because I read somewhere that it drains the battery. Just for the kicks, after a few hours, I unplugged and re-plugged my phone. Suddenly, there was light. The battery light came back. I immediately switched to the wall charger and once I did that the battery icon appeared showing 1%. Now, it's peacefully charging away. Will see if it actually turns on later on once it's charged about half an hour.
