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.

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.
So my stock LG G2 just suddenly stopped working last night. The battery died, and I haven't been able to boot it up since, even after charging overnight. The only kind of response I get from it is if I hold the power button, there is a short vibrate every 2-3 seconds while I'm holding it. Sometimes after ~15-20 seconds it will stop vibrating, other times it will keep vibrating every few seconds until I give up on holding the button. Other than the vibration, there is absolutely no kind of response from the phone, no charging LED or anything like that. The same thing happens regardless of whether it is plugged in and charging or not. I've tried connecting it to my computer, but the device just isn't recognized whatsoever, so I can't use adb to try to boot to recovery or anything like that. I've rooted my G2 in the past, but I believe that I've had it replaced since then and the new device has always been completely stock.
I'm completely at a loss for what to do, it seems as though the device just bricked itself. I'm hesitant to try to get a replacement device through Verizon, as I'm only 4 months from an upgrade and will be getting a completely new phone then anyway. Does anyone have any idea what could possibly have gone wrong or how I could go about fixing it? If I have to wipe everything that's fine, as I was going to root it and install a custom ROM soon anyway.
Right now, my only idea is to get something to hold the power button down and let the phone vibrate until the battery dies, but that will take a while and isn't too likely to fix the problem. I'd greatly appreciate any advice from anyone who might know how to fix this.
My S4 has finally kicked the bucket. It turns on long enough to display the "Samsung" splash screen with the padlock icon that says "Custom." After about two seconds it instantly shuts off, and can't be turned back on.
Pull the battery, the phone automatically turns on, shuts off again, rinse and repeat.
At this point I just want to salvage my pictures and music from the phone; is there any way I can mount the internal SD in the state that it's in? I'm sure this power issue is hardware-based; I can't get into recovery or download mode before it shuts off on me.
I was having this same problem recently as well. It happened on two separate occasions with about a week in between. The first time it came back after a few battery pulls and attempts to boot to recovery as well as download mode. The second time I fiddled with it for about an hour with numerous battery pulls and attempts to boot to recovery and download mode. I even swapped batteries to no avail. I don't know why exactly it finally decided to boot, but I haven't had an issue with it since. Maybe keep trying and hope for the best?
Can you boot and stay into recovery or download mode?
If not, then it very well might be a button issue. Have the phone checked out or you can do it yourself with a voltmeter if you have the knowledge and tech. Otherwise take it to a professional. I paid around 15$ to a button replaced. Which kinda seems a lot, considering a set of 4 buttons costs about 5$ and then you can do it yourself since it doesn't appear to be that hard, especially if you've done soldering before.
Hello everyone!
My parents contacted me asking for help with some phone issues that I thought would be minor but this is now something I have to submit to you guys because I just don't know how to tackle this issue;
I've got an unmodified, completely stock AT&T Samsung Galaxy S4 that has been owned since launch. My parents were initially complaining about how the phone stopped charging and wouldn't turn on. I thought, "Easy, dead battery, it's been 3 years so how could it not? It might not be delivering enough voltage for the SoC..." but i'm not sure that's the full story which is why I want your guys' opinion since this place is a wealth of knowledge.
Things that are known:
When you charge the phone, the basic "battery charging indicator" that is shown when Android is not booted into or powered on freezes, or sometimes does not detect a battery so does not even turn on. Doing battery pulls seems to change how the phone responds. This is what my parents were experiencing. I thought, either dead battery, dead micro-USB cable, AC adapter, or charging circuit within the phone. Since this was obviously a big job, I took the phone back home for this weekend to play with and now this is what i'm experiencing.
So I got the phone to charge using one of my AC adapters for some reason, despite using the supposed broken charging cable to transfer data successfully without corruption using my own phone (LG G2) to confirm if it was just the cable. So now the SGS4 has a battery that is 100% charged, I turn on the phone and tried various methods to get the phone to boot successfully back into android. The first obvious one was to boot into safe mode using PWR, letting go of PWR, and then pressing VOL UP. It booted ONCE or TWICE successfully into safe mode into android, it shut off after 5 seconds being into the system due to low battery. This was BEFORE I was able to successfully charge the battery to 100% with my AC adapter but has failed to boot since.
Now since I've been failing to get into safe mode as when I boot the phone up, the phone freezes or has graphical glitches at the Samsung post/splash logo as seen here:
After some desperation, I considered using KIES/Odin to reflash, but mostly I tried going into download mode to see if the phone would even go into it by doing PWR + VOL DOWN. It did get into download mode but it froze/restarted forcing a battery pull and ever since then I keep getting occasional error messages such as "System software not authorized by AT&T has been found on your phone.", or this screen with a Samsung logo and an open padlock. I notice sometimes that when I'm at this open padlock screen, it sometimes begins to boot into the system but quickly freezes when it plays the boot jingle:
At any rate, I ordered a new battery but I fear this might be EMMC corruption or just something I don't quite understand. The phone has valuable information that I have to recover despite my parents CANCELLING a backup of the phone, they failed to heed my due diligence and are now freaking out about the data (photos, contacts, etc). I just need the phone to boot so I can make a nandroid backup, export the contacts, transfer media off the phone and wipe this thing and start anew. However i've already let them know that it might not be possible. The most important thing is to get this thing out of this soft-brick?
Please help because I have no idea where to steer this ship from here on out aside from waiting to receive that new battery and hope these instability issues are caused by low voltage. I had an SGS2 which had the crazy EMMC bug so I'm hoping its not EMMC corruption.
Thanks for your time everyone! I'll update this thread to reflect new information as I play around with the phone.
Edit: Here is a video, I go through a lot of the same information posted in this thread but here it is.

Possible loose connection inside the phone? Was the phone every bumped, dropped, or exposed to moisture?

Not that I know of. I'm going to check the water damage stickers if I can to ensure that's not the case but i've been told it was sudden. It had been dropped once before but had been working fine for quite some time up until recently.
Maybe the effects of the drop and manifesting themselves now?
Hi people.
So i'm having a problem with my S7 Edge and i don't think it is common. A few weeks back I was using my phone and it would suddenly turn off and the battery would be drained too. After this first incident with the problem it happened more often, and the phone would start doing boot loops to the point where the phone just froze and turned off. When these problems occured it will usually need to be a problem where I do a safe boot (Volume up, Home button and power key), and everything will be fine (or to charge it if the battery drained), but recently, the phone just didn't work at all, to the point I waited for the battery to drain (10 hours), and try charging it, nothing happens.
So firstly I was watching a video and checking my CPU/Battery tempretures to see if that was the problem (the tempretures at the time were around 31 degrees), and mid way through the video it bugged out through the audio in a high screech and turned itself off.
I tried turning it on again but no response to the screen, i tried safe booting it, or every alternative booting option, it did not work at all.
Here is all the diagnostics and repairs I did, but no luck:
- Tried turning it on
- Different boot options (Volume up/down, Home button & power key)
- Cleaning the port for moisture detection
- Replacing the battery for a new one (Genuine one)
- Doing all of the above, with it on charge
- Connecting to a PC, but no detection
One positive I found was that when i put the phone on a wireless station, it would change colour to show that the phone is charging. I have however took the wireless out of the phone as it was in the way of the battery, and safely in my draw.
Before this final fault happened, I did do a recovery to a previous Android version, just incase if it was a software fault, but it wasn't. The phone is not rooted and I had it since September of 2016.
Is there any alternative options to do? As i'm running out of ideas to do as every solution on the internet is to turn it on, which i can't whatsoever.
The warranty is voided also as there is a crack on the screen lens, and it's way too much to pay for a repair.
I need some explination of why this is happening, so I can go in the right direction and not to waste money if i was going to a repair service, or purchasing the parts for myself.
Any help would be highly appericiated.
Check your installed apps to see if there any viruses on your phone. All you said are signs that your phone might have a virus (check how to remove it here: https://www.unlockunit.com/blog/how-to-tell-if-your-phone-has-a-virus/
However, there is a chance that you do not have any viruses on your phone, but at least you have to isolate this possibility.
Did you recall installing any app prior to this behavior?
This may be the case, however i can't turn on the phone at all. I tried every possible reboot possible, download mode, bios mode, safe boot, reboot, but nothing happens unfortunately. Unless i can do it whilst it is turned off, i can do something. I have a PC if i can do anything else with it.
I don't think I have installed any weird apps on the phone.
sounds like a brick to me. Not a lot I can thing of you can do.
If you place the wireless card back in does it boot?
IT sounds like you've messed with the internals, so possible you damaged something?
I don't particularly think that I broke it from the inside as it was behaving the same before i opened it. And when i used the wireless charging, it will only indicate it was charging or getting detected on that charging pad and not on the phone regarding a red led, or the charging icon
Have you tried holding volume down + home + power for 15 seconds and try turning on the phone again?
As mentioned in the description, I have unfortunately
