[Q] LG G2 Won't turn on, cannot get to download mode

My AT&T LG G2 (plain D800) is rooted, and has Xposed installed on it (I'm not sure if this caused the issue or not), but here's what I'm having problems with:
I was playing a game, when all of a sudden the phone froze (no biggie, it's done it before, I've held the power button to force restart it, and it works), but the phone shut off on it's own, and would/will not turn back on.
Tge LG boot logo comes up intermittently when I hold power and volume up, but only sometimes. The phone has only twice now gotten to the AT&T logo, but freezes immediately and shuts down. I've tried literally every combination of holding buttons, for up to 70 seconds at a time, both on the charger, off the charger, and while plugging into the charger.
I cannot get to download mode, I cannot get to TWRP, and can obviously not boot into the phone. I had made no changes in weeks prior to this happening, so I can't see why or how something with my phone being rooted would cause the problem.
I've left the phone charged overnight before performing the actions (the phone won't even show battery percentage), so I don't think it's a dead battery issue. Everything I've read so far seems to say that the battery chip has died and needs to be replaced. Somehow I don't think it's the problem.
I'm fully willing to completely wipe the rom, and everything on it, as long as I can get the phone working again. However I cannot boot into download mode to use ADB or anything.
Is my phone completely bricked? Or is there a chance that the battery chip really is fried? Please help!
Update!
I left the phone charging some more, and decided to try volume up and power (while plugged in). The phone actually went into download mode for about 5 seconds before shutting off again. I tried doing the same steps, but nothing will come up again. It appears to be an issue with the battery on the device. Does anyone else think otherwise? Or will I have to send it in for a new battery? (The phone is less than a year old so I don't want to void the warranty anymore than rooting, which they wouldn't be able to tell since it won't turn on anyways).
Update Again:
I can get the phone to show the LG logo/download mode on a fairly consistent basis, sometimes showing a static screen (colored noise, not monotone), sometimes a blue screen, but it will shut off after 5-6 seconds every time.

Hey, I do not want to announce bad but by your description it seems that did you mother board, go to the lab to make sure, I had something similar and I replaced the motherboard and my phone came on time, check if the device is still under warranty has a good chance to replace you under warranty, good luck.

[Q] Help with potentially bricked S4 [Xposed]

--- This may belong in the Xposed forum, I am uncertain. ---
Hello. Please forgive my ignorance regarding the technical aspects of methods discussed on these forums.
I have a Samsung Galaxy S4 GT-I9505 supplied by Vodafone Australia. This was received today as a replacement for a screen issue I had with my previous S4. On the previous S4, I had rooted using a Saferoot method as read about on this forum. Later I had installed Xposed to use Keepchat and everything was fine. Today I have rooted this replacement phone successfully using the same method, and then moved to install Xposed. The Xposed application required an update, the very first option in the app was red and suggested an update or a reboot, and the reboot did nothing, so I pressed update. The phone turned off but didn't restart. I tried the usual button presses and battery pulls and finally a simple power up using the standard power button started the phone up. It got as far as the lock screen I believe, before shutting down again. It is now unresponsive. It wont turn on, enter the boot menu (multi button holding method) or charge. I believe the battery is quite low at this point, and unable to charge, causing me some consternation. It has now been over 30 minutes with no response.
If anyone could provide a resolution to this issue, I would be extremely thankful.
Regards,
CaleS

Hello again.
I have an update on my situation.
I left the phone on charge and it eventually turned on by itself. I played around with it for a while and it seemed OK. Eventually it turned off again. I had to pull the battery to get it to turn back on. After starting up again, getting to the lockscreen, it turned off again. This process repeated many times, until I got frustrated.
The next day I thought I'd try a factory reset via volume up + power, and the device managed to stay on long enough for this to complete. After the phone reset, I used it for a while and again it turned off. The same cycle continued.
Perhaps the phone is naturally faulty, despite my rooting attempt, as it was a refurbished model. I am quite happy to return it for another replacement under warranty, however I may not be able to do it as the device is rooted. I would gladly remove the root using stock firmware and Odin, however the phone resets after a few seconds of entering download mode.
Any advice?
Thanks.

Sounds to me you have a faulty power button. It's somehow stuck that's why it even reboots in download mode. It's a common problem for the S4. Try to wedge it or replace it.

if it is refurbished model it might as well be dead battery.
battery sensor detects "low battery" state and shutdown phone saying battery 0% - to protect battery against fully depleted state (damaging to max capacity or even impossible to charge at some point)
if you power it on again it will boot and say it has like 1% left and you will be able to use it for few more moments, but doing so will degrade your battery.
powering it on, going to lock screen for it to shutdown on its own again sounds like weak power source
imagine above scenario happening several times (previous owner of the phone kept "reviving" it after shutdown due to battery 0%)
that would resulted in battery able to hold only fraction of its standard power - allowing you to just boot your phone before it shuts down.
I had similar situation with my laptop battery (this one was on AC all the time) - battery was so damaged that laptop was shutting down at windows login screen - if booted on battery alone.
When booted on AC and unplugged it said 100% battery, that went down to 0% in a matter of around 2 minutes, when laptop shuts down.

Samsung S4 VE I9515 wont turn on

Hello,
So let me give you a brief so you'd know everything - a few days ago, I'm gonna call it day 1, I walked under light rain with the phone in my pocket, it worked until the night of
Day 2 - started to lag a bit, it was like I was running some heavy apps and like the ram was insufficient. Restarted the phone, everything seemed normal.
Day 3 - Phone went off while was browsing. So I have to make a note here. I was running cm13 with android m and twrp 2..something and there were occasional reboots by itself rarely prior to Day 1. Also, I was using a supercharger (or whatever it is called, it is a charger that charges faster) for about a month.
So when the phone went off while I was browsing, it started by itself and stuck on the android loading. I restarted, cleared dalvik and regular cache - still stuck on boot. Flashed many times, changed the recovery to twrp, and still was stuck on rebooting and occasionally it didn't turn on. There were random occurrences of errors on flashing roms, which never happened before (for example, "cant mount system or data"). Within the time passing by, the phone started not to turn on when I tried to. By this time rarely got stuck on the first boot screen saying with the text "Samsung S4". Yesterday, Day 4, the phone never turned on, except one time. I don't remember doing anything special. I just pressed and held the power button and it turned on, but went off shortly after the android boot animation appeared.
Also there was times on Day 3, when I was trying to boot into the system, it got stuck on the android booting animation.
On and prior to Day 3, while I was charging, whenever it is on or off - I had the indicator light for charging. Now when I plug it in to charge - nothing happens.
To skip any unnecessary questions, I will make a short QA.
Q: Did you tried to boot into recovery/bootloader?
A: yes, nothing happens
Q: Any sign of life on adb while connected to a pc??
A: no
Q: Is battery dead?
A: I don't think so, but actually I'm not that sure. When I connect a separate led light to it, the led lights up Whatever, if it was a faulty battery when I plug the phone on the charger, it should've worked fine.
Q: Why don't you just buy a new phone?
A: I was planning to buy a new one, but after just 4 months when I have to renew my contract. I don't want to buy a phone off contract.
Q: Are you stupid, if you can't manage to fix it by yourself, why don't you give it to a repair?
A: I truly believe that the professionalism of repairers doesn't exist in my country via old experiences with them.
So in the worst scenario I will loose time by trying to fixing it and for 4 months I will use my old android phone.
In the best scenario, my almost 2 years old phone will revive.
Also, I have a multimeter - I can check the electricity. Just tell me what to check.
Thanks.

Probabily the rain damaged a part of your hardware. Did you solve?

If the battery is dead, the phone won't work.
The battery needs to have at least a bit of charge in order for the device to work, even if it is plugged in.
If the battery can't hold the charge, and the device uses more power than it gets, it turns off. I speak from experience.
These devices don't seem to work without a battery. Power goes to the battery, and the phone takes the power from there. Power doesn't go straight to the phone.
Anyway, I don't think a bit of light rain hurts the devices, especially if it was in your pocket. I walked through rain with my device in the pocket many times and no problem.
It looks to me that the hardware is failing. I don't believe that a faulty battery can cause a bootloop. I also don't believe that the power button causes a bootloop.
What I suggest would be:
1) Try going back to stock ROM.
2) Maybe try to get an S4 with a broken screen and switch the motherboards.

Phone suddenly wont turn on

I woke up this morning after realizing my alarm on my phone didnt go off. When I went to check my phone, I found that it won't turn on.
I tried the Volume Down + Power for 15 seconds, 30 seconds, and 1 minute. I also tried safemode Volume Up + Power for 15 sec, 30 sec, and 1 minute.
Tried connecting to the computer to see if I could adb reboot it but the phone isnt being detected by adb. I can hear it connecting and disconnecting constantly from windows.
I put the phone on the charger last night at about 60% charge, so it should have had enough battery to sit unused for a few hours but it was only about 6 hours later that I noticed it wouldn't turn on.
Right now I am just hoping the battery bugged out and drained so the phone is sitting on the charger charging up but there's no signs of life. My phone has been fine for a month with the September patches and fine before that. I havent taken the october patch yet.
My phone is a little bit over 2 months old.
What else can I do and what would have caused the phone to suddenly not turn on?
Update: Phone has been charging for about 2.5 hours. It is charging at a constant 11mA (0.11A) and has taken in about 220mA. The screen still hasn't came back on. Email sent to Essential a few hours ago, no reply yet.

I'm from Mexico, but I do not know if my equipment is still guaranteed, is there any way to check if it has a guarantee? because I do not want to have a nice paperweight.

Phones purchased in the US come with a 1 year warranty.
I would assume Mexico would get a similar warranty.
You will need your original proof of purchase.
Contact Essential and explain your situation, they will probably be able to come up with a solution for you.

Click the “?” In the lower right corner and send them an email that explains your situation.
Couldn’t find a Mexico support link. Even using my VPN set to Mexico, it gave me the US support page.

I thank you for your attention, I let it be completely discharged and I have connected it to charge right now and on ... I am happy !!!!

Same problem here, actually my phone was on but screen would not come out of wake. Screen would brighten slightly when combination of buttons pushed,
This happened to me after about two weeks of use, first time it happened I was able to make it come alive by playing with buttons. Than about a week later after having it charging it would not become active.
Emailed Essential with problem, they sent out a replacement unit.
First time I had problem, I was on PIE non rooted, when it finally died I was stock rooted PIE. I don't think rooting had anything to do with problem since it happened even before root. Network Sprint

good morning to all, I hope and can help my team last night when I was watching videos after 2 hours the screen froze so I decided to force a reboot with which I thought the problem would be solved, but to my surprise it was not like that, the phone when turning on did not give imangen only the screen cleared so I knew it had been turned on, but never gave an image, I let it completely discharged thinking that with that it would be fixed and nothing, I put it on and when I turn on the same thing happens it clears the screen but it does not give an image, try the button convention and nothing that solves it, someone has had the same problem? the phone and try tentadilla unlock and put music in spotify so the touch and sound work, also frame and enter calls as well as calls by messenger! help

Mx10 Pro strange behavior

Hello to everyone.
I have an android box MX10 PRO that used to work for 1.8 years. 3 days ago it started to restart himself end never stayed on but kept doing it. I turned it off. Now the strage thing is that it start and you can use it for 10 min. Than it turn off. I re insert the power and the blu light indicator is very low, than it goes away and the device does not start. I let it cool because i thought it was for the CPU temp, but does not start. The next day it started again. You can use it 10 min and goes off again. It seems like it want to work only 10 min a day . Very strange. I want to say that till now the device never had heating issue. I was impresed about that. But i'm not understanding the problem now. I think we can exclude the firmware because the device cannot even power on, so it is not firmware. I was thinking about the CPU. But does not seem overheating problem.
Anyone has faced similar issue? Any idea?

Yesterday i reinstalled the ROM to be sure is not a firmware issue. Nothing changed. But, the thing i noticed was this. The device can be power on by the USB port. So i tested a phone charger 5V-2A and the device start till the ANDROID logo, than it restarts everytime. With the power supply the situation is the same. It works after about 10 hours and for only 5-10 minutes. Than it does not power on at all.
