LG G3 stuck again!

So it's the second time my G3 gets stuck and won't come back to life. 6-7 months ago it was stuck onto the firmware update screen (thou I never messed with rooting and stuff) and I had to send it back to LG Italy since it was still under warranty. They just wiped everything off, replaced something and sent it back to me.
Today's problem: Phone was off this morning and when I tried to turn it on it seemed like battery was dead. Charged it and turned it on after a while, got into home screen and a weird message about whatsapp loading issue because my phone time wasn't correct. On top of that the phone was totally frozen and didn't respond to any imput, so I had to remove the battery and put it back in. From now on, the phone is stuck on logo screen. Tried to put it in download mode, I see the firmware update screen but my computer won't recognize my phone via pc suite. Recovery mode won't even start. Tried to turn it off and just plug it into my wall charger: the empty battery icon with the loading symbol pops up and everything seems to be stuck, even if I unplug it the icon would still be there. I tried with two different batteries getting the same result
Totally clueless about what to do now (the phone is still under warranty by the way).

LG3 wont boot + Blue screen

Hello, i faced a serious problem this evening, just after i finished a call phone, the screen of the phone went Blue and then it went off, i started to put it on again and then it showed the screen with LG and then it went black no boot at all. i removed the battery and i tried again and still the same, so i tried to remove the battery and put it again and plug it with the computer, it went on with charging battery and then suddenly went to blue screen again.
So i tried to put the recovery mode with power down and on/off and it worked i got the recovery mode screen with factory reset but it was only with factory reset, i tried it and then i put yes and it reboot and then after LG screen, it went black again....
so i tried to put download mode with usb cable but it wont, always i got the blue screen. what should i do, where is the problem exactly for people who had the same problem ? the batterye ? the motherboard ?

anyone to help ? i changed the battery and it wasnt coming from it, and the phone showed others anormalies like sometimes u can charge the battery and you see the % and sometimes it goes blue screen and shut down. anyone had the same issue before ?

My LG G3 randomly started giving this problem for 3-4 days till it went completely bad. It just wouldn't get past the Blue Screen. Since I had to take a backup before taking any further action, I have been able to get it up and running for very short durations by keeping the cell phone in the freezer for an hour or so. Yes. I am not kidding. After it freezes, I can get it up on about 5th or 6th attempt. Sometimes even more. Be mindful that the battery is now showing a red humidity marker due to the freezer.
I am thinking of asking LG to repair it. What a piece of crap. Its only 18 months old for me.

S4 mini wont turn nor charge but can connect to pc as qualcomm HS-usb QDLoader (9008)

Ok, so recently i got a replacement for my broken s4 i9505 a samsung galaxy i9195 s4 mini so as soon as i laid my hands on it i instantly went to install the cyanogen mod for the android 6.0 i was constantly updating the phone via the cm updater on the phone. So last night i turned off my phone went to sleep woke up next morning turned on my phone it vibrated and everything i went to eat something and left my phone in the room i came back tried to unlock the phone and found out that it turned itself off randomly so i tought that battery is at 0% so i turned it on again and connected it to the usb to charge it up watched youtube on my pc for about 10 minutes eyed my phone and saw that it was stuck on the first samsung logo the one before the recovery that first pops up when you start the phone so my mind went kinda "wtf" so i unplugged the usb took the cover off and took my battery out placed it back in and tried to start my phone and it doesn't start or charge i tried power + home + volume up that doesn't work so i tried to connect it to pc again and it shows up as qualcomm HS-usb QDLoader (9008) (http://prntscr.com/dcoono) so im thinking that something went wrong or the phone forced to update itself but i don't think so cm updater does it automaticly i've always doing it manualy. The phone bricked itself?

Whenever my s4 mini drains completely I will get ZERO response from it until its connected to a high amp charger for a while or i charge the battery on an external charger first. This really had me scared a bunch of times as well, hopefully that is your case. If you know the battery is charged id start by going into download mode (volume down) and starting over with a new recovery.

Phone was stuck on bootloop, now won't turn on or charge

Yesterday my phone got stuck in a bootloop (wouldn't go beyond the htc logo screen, recovery was still accessible) after turning itself off (from being too hot I think?). I turned it off via recovery as there was no other way and I wanted to look into the problem now, but the phone won't even turn on anymore. It doesn't seem to charge either (at least the LED doesn't light up).
It's running Android 4.2.2 I think (the latest officially provided) and is rooted. I did not change anything system related recently. The last "noteworthy" things I did were updating a game and "playing" it for maybe 30 minutes (I use quotation marks because I think I left the game running but stepped away from the phone for like 5-10 minutes, but I can't say for sure; it was turned off when I came back), until itself shut down.
The only suggestions I could find for phones that would not turn on or charge were trying different cables/power sockets and removing the battery. Tried 2 different cables on 2 different sockets and my PC; removing the battery it not really possible with this phone...
Any way to fix this?

[H815] Phone keeps rebooting when charger not connected

Hi all, I got a serious issue, it's going to be a long post, because I want to provide as much detail as possible, so please read my whole thread!
My LG G4 H815 keeps rebooting whenever my charger isn't connected, effectively making it unusable.
When I unplug my charger, my phone could be OK for like a couple of minutes, but then the screen would suddenly go black, the LG boot logo appears and tries to boot back into my ROM.
Once i'm on the simcard code insertion screen, I would type my code as usual, but upon pressing the check mark, my phone emmidiately shuts off again and reboots again into an endless rebooting cycle like this:
Black screen -> LG Logo -> Custom ROM boot animation -> Simcard code insertion screen -> I press the check mark after typing my code -> REPEAT EVERYTHING.
(Sometimes I'm not even done typing my code and it would still reboot)
I don't have the official charger anymore that comes with the phone and I don't remember what happened to it and where it is (I think it was broken or something), so I've used a very different charger for quite some time now.
I've had bootloop issues before back when I was still on stock LG firmware, unrooted and covered by warranty, I've sent it back for a repair once but now it seems that i'm having a problem again.
My warranty period is long expired, so returning it now would be pointless.
However, maybe the problem could be the battery as well, meaning that it might not be a faulty motherboard after all, but I'm not sure.
I tried shutdowns for cooldowns, a cache wipe, pulling out the battery and putting it back in, charging to 100% while the phone is off but all without luck.
I've had this problem on CypherOS, LineageOS and on AICP (which are all the custom ROMs that I ever tried on my G4)
PLEASE. HELP. I can't take this anymore! I have to constantly use my phone plugged into a charger and it's become impossible to use it without it! :crying:
(EDIT): Nevermind, I solved it by getting a new battery 2 months ago.
