My phone was stuck in the connect to PC (phone..!..PC) screen after being left in download mode for the night.
I connected it to the wall charger and when it showed that screen, I turned it off, I turned it off a few times and then connected it to the USB and use heimdall "close-pc-screen" option to recover.
Wanted to share this if anyone faces something similar.

Was plugging in my G2 to charge it and suddenly it had this screen. "Firmware Update. Do not unplug the USB connection until the process is complete."
How do I exit safely? Will I corrupt any data or damage anything? I was only plugging in my phone to a wall socket, so I don't know why there would be such a screen. Help anyone? >.<
Someone knows how I can exit safely? >< Please?
That sounds like its in download mode, which you get to by turning off the phone, then plugging in a usb cable while holding vol up. I always assumed the usb cable needed to be connected to a computer for that to happen, but maybe it works if it just senses power.
Anyway, if the bar isn't going anywhere (and it shouldn't be since its not connected to anything feeding it data) then you should be okay unplugging it and turning the phone off, then back on.
Edit: Just tried it with my phone - turned off, then connected USB cable/wall charger while holding vol up and sure enough it went into download mode. I unplugged the cable, then held the power button until the phone restarted. Booted as normal.
My Lg ls740 prompted me to do a system update 3days ago and has not came back om since. It just keeps flashing from LG logo and the android man...i have tried taking battery out...factory reset...and everything above . Can anyone help?!?!
So a few minutes ago my G2 was charging at around 35% when it just shut off. It wont turn on and when I plug in my charger, the light won't show. When i plug it into my computer, it can detect something because it looks for drivers. I can't really find any other cases of this so I'm lost. Suggestions anyone?
The other morning I woke up and my phone would not turn on after being on the charger overnight on the night stand.
I removed the battery, power drained the device and still the device would not post.
So I grabbed my spare battery and tried that, still no post.
I plugged in my device and noticed the charging light was not coming on, so i tried a different adapter and yet again no change.
I disassembled the phone and swapped out the USB flex cable with a new one, still no change.
So I plugged the device into my computer and I received a battery gray battery image that flashes away almost immediately.
I unplugged the phone held the power button down and plugged the phone back in. I received the Samsung writing with the model number but the device just goes back to the grey battery and flash away,
I attempted to boot the device to recovery mode but it just loops back to the grey battery,
I had then decided to try download mode with odin and restore the stock ROM. I can get the device into download mode but no computer recognizes the device in device manager or odin.
I have removed and re-installed the battery while in download mode and any computer will still not recognize the device.
I noticed one strange thing. If i remove the USB cable from the phone while it is plugged in the phone powers off and will not turn on until it is plugged into a power source.
It is almost as if the phone does not recognize that the battery is even plugged in!
If anyone has any ideas or could possibly point me in the right direction that would be greatly appreciated!
Thanks guys in advanced if anyone can offer any information on this issue!
Also, the phone is out of warranty!
My Axon was at the twrp menu at 1% this morning so i went to shut it down to charge it but i havent been able to get it back on since. At first, plugging in the charger would prompt a light vibrate and red LED every few seconds but this has slowly stopped and the red LED only flashes every so often when i hold the power button. I've been trying to get into EDL Mode but with no indication from the phone, along with no indication of connection from the computer, I've been unsuccessful. If anyone could offer me some help to even get into EDL mode so i can flash out of this, that would be great. Thanks
Maybe forcing the EDL mode, using a moded USB cable:

Search for the cable and instructions on that link
It seems like it's trying to boot into EDL mode but the battery isn't taking a charge. Have you tried connecting the phone to the wall charger for like an hour and then connect it to the PC?
Hello guys !
Yesterday I was changing the earpiece on my yotaphone 2 but to test it I've tried to power on the smartphone without connecting the 2 flat cables of the EPD screen and the phone became crazy: bootloop with the "powered by android".
After a lot of Attempts I managed to install RU Lollipop rom (I had MM firmware before) with yotaflasher, but the phone ins't working correctly:
With turned off phone if I connect battery nothing happen, but if I disconnect the battery and then connect usb cable there's a bootloop "powered by android", but if I connect the battery during bootloop the phone starts itself correcly but the battery is 0% (it's fully charged, measuered with tester 3.8V) and if I disconnect usb cable phone turn off because it read 0%.
If turn on phone in fastboot mode and connect the battery it stays turned on also without usb cable.
Additional: if I turn on yotaenergy the phone seems that it's charging (battery % increase really slowly) and if I disconnect the phone it stays on for some minutes.
What can I try to restore the normal behavior?
(tonight I'll try to flash android MM via yotaflasher btw)
Thanks to everyone and sorry for my poor english
