Hello, my friend's lg g2 keeps rebooting while plugged on charger, i even can't enter recovery mode or download mode, it reboots somewhere in the middle (for ex. text "loading" comes up and then phone switches off).
if i press power button the same happens but it doesn't loops as it does while charging.
i think is is mostly hardware problem because the battery is swollen, so am i right or not?
and also the screen is broken but i don't think i is the reason of problem

My phone won't turn on and when i connect it to the charger sometimes it shows the charging icon and then goes into a loop, and sometimes it shows the charging icon one time only and then it dies.
Also if i try to boot into download mode, it works but it stays for like 10 seconds and then reboots, so i guess maybe the power button is faulty and always pressed?
What do you think?

Hello Guys
My lg g2 has a very strange problem !!
Every thing is operating normally in the phone till battery reachs 60%
Once it be 60% the screen stuck in black most of times
Knock feature doesn't wake up the device, also the power button
After pressing 10s times on power button and knocking on the screen sometimes open sometimes not.
It needs to be plugged in wall charger to operate semi normal (it works good in the charger but it do stuck for one or two times only)
I noticed that the screen is Lighting up but it shows black only no data at all
And some times gives black only.
I tried to restart my phone. It restarts normaly but the screen still black even lg logo didn't appear but it opens with black again.
The screen is working i can hear my touch sound ( swipe look, answering phone call, volume up and etc.)
All this happened only once the battery reachs 60%
My devise not rooted, updated to lollipop, i did hard and soft reset, connected the devise to lg pc suite
Nothing helped. Also my battery is draining super fast even in charger !!!
Do you have any ideas? Is it battery problem or cables or what?
Any suggestions??
Hi,
I have a problem regarding my unit. I am not very good in this stuff because I just started. I had someone root my phone for me and I learned how to flash custom ROMS. I had a custom ROM flashed and my phone was working fine. then I got bored so I flashed a different ROM but then I noticed some annoying features of the ROM so I switched back to last custom ROM I had ( the first custom ROM I flashed). One night my phone got fully drained so it turned-off. When I plugged the charger in the phone showed a symbol of a battery charging for about 3 seconds then it turned off. It did not turn on again even after I pressed the power button. I took out the battery and plugged it in the phone and then the phone automatically turned on and showed the name of the unit only (white text on black background: "SAMSUNG GALAXY S4") and on the top left of the screen appeared some text ("kernel is not seandroid enforcing" and below it is " set warranty bit: kernel"). I cannot access recovery and download mode( in a way) because when I plug in the battery and hold power + home button + volume up, in the top left corner of the screen, it states that it is in recovery mode but even before the TWRP could start, the phone would turn off immediately. Same goes for the Download mode. I can reach up to the part where I would choose whether to continue or not to download mode but even before I could make a choice, the phone would shutdown immediately. I have been using custom ROMS for almost a year now and never had a serious problem (aside from the part where my phone at times suddenly reboots for no reason at all) until that night where my phone ran out of battery power. Now i tried charging the battery using a clip charger because I was thinking that maybe the charging port of my phone is defective, but as it turns out, I didn't have any luck at all. I tried to plug in the battery again and the phone turned on automatically (without pressing the power button) but the problem remains the same. can anyone please help me regarding my phone problem? it would be very much appreciated.
Thank you

Your power button is stuck/faulty.
It's common problem on the s4. Try to wiggle it loose or replace it.

It's the power button.
Your device will not turn on because the power button is stuck in the pressed position.
Replace or try to loosen it.
I have a galaxy s4 (i9500) and got it in used condition, a year ago. Never suspected a single problem in it.
Today I powered off my mobile for charging then after 25 minutes I took it off. I held the power button then I saw my boot logo(Where there is written Samsung Galaxy S4 GT-i9500). That logo kept showing as usual for 2 seconds and screen went black and again that logo appeared for 2 seconds and screen gone black and again it appeared, so, I'm stuck in kinda loop not a bootlooop exactly(maybe because bootloop refers to being stuck on boot screen while in my case its boot logo). I then removed the battery and inserted it back after an hour and as soon as I inserted it back the mobile itself turned on as if I held power button but this time again I was stuck in that loop. Moreover when I tried going into download mode, I didn't even need to hold the power button along with the volume down and home, it itself proceeded to confirmation screen of odin mode. And after that confirmation screen appeared saying that whether I really want to boot into download mode, disappeared itself after like 3 or 4 seconds even though I didn't press any key. And in case I press vol up key confirming to boot to download mode, then it again takes me to that loop. I'm too much confused . I can't even flash the firmware as it won;t boot to download mode neither am I able to boot into recovery.
Now do u really think the problem might be the power button(Which is maybe stuck in the state of pressed).
Or else it can be the battery coz my battery is also just average not too good?
I also inserted the command( in build.prop file) for enabling nav. bar and the code was correct but I never rebooted after inserting that. this was the first time I rebooted after that.
SOrry for some bad English.
Do you have something like this? I'm now having problem with getting my phone back to work...

From what you say it seams like power button problem, try to start the phone and connect it to the charger. When it start take out the battery, it will be powered by charger and you will eliminate battery problem.
Hi, I've got an LG G6 smartphone that got the wrong flash method. It turned off and it did not turn out any longer. It showed me how to deal with its boxing and flashing. After a while, it suddenly turned off, and it was not turned on again, just when I plugged the phone into a charger. The red question mark that appears in the middle of a battery. Even when I connect it to my computer, it shows the same symptom and my computer does not detect the phone. You can easily retrieve the phone, but the phone can not be flashed. Saying the slave problem. Please inquire. The phone is now totally silent. When charging or charging, I'll show a red question mark in the middle of a battery Does not respond to any buttons. It does not scroll to fast boot or recovery mode. May it be a battery problem. Thanks
