Hello everyone.
I'm in a very tough spot in the recovery of my LG G2 smartphone.. I've tried every single method under the sun for the G2 (d801) to no avail. My latest attempt to unbrick this thing has been to use the LG Mobile Support tool off of the LG website. I've downloaded and installed the tool, clicked "Options", "Upgrade Recovery", entered my IMEI number in the "Enter the phone info" dialog box, then when it gets halfway through... around 48% complete saying "Checking battery power level" or something along those lines, then fails with the error "Battery level low, upgrade is unavailable. Upgrade halted by lack of battery power may cause serious errors in the phone software. Recharge the battery fully and try upgrade again ".
I am unable to get the device to charge because when I power it off, then plug it in, it begins looping at the LG logo... It'll stay black for 5 seconds, light up the logo for another 5 seconds, wash rinse and repeat... It's been like this for over 3 weeks now... I've left it in the looping state plugged in for about 7 days now, and it still comes up with this error. I've read on another XDA thread that it does charge while looping, but the mobile support tool doesn't seem to realize it.
Anyways, any help is greatly appreciated. My device has been bricked since August 23rd.

Did you fix it/ find a way?
I have the same problem. "Battery level low, upgrade is unavailable. Upgrade halted by lack of battery power may cause serious errors in the phone software. Recharge the battery fully and try upgrade again. "
But my battery is at 100%!!! I tried it at 70% and first got the error. But when I was at 57%, I didnt get the error.
Take your battery out. Put back in. Dont power on phone. Just plug in a normal charger.
See if that charges your bat without needing to turn it on. The screen still turns on to show the %.
(But when I got to full power, the error message didnt go away).
t5678. No, I was not able to find a fix. The G2 is unibody, therefore the battery cannot be removed. I have left the device on the charger for 24 hours, and it still gives me the "battery level is low, upgrade unavailable" message in LG Mobile Support Tool. Despite people saying "Try it in x86", and "try it in x64"... I've tried the exact same method in Windows 7 and 10 and none have worked so far...

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.
Hi,
as some of you I've got sudden shutdowns between 10 - 15 % on my Nexus 6p, which is now nearly a year old. I think the problem started around the same time that I installed Android 7.0, but I cannot pin it down to that.
I've tried the following from here http://forum.xda-developers.com/nexus-6/help/solution-phone-shutting-battery-empty-t3041226
Problem: I don't have that option... tried every other article to completely drain the battery, no luck.
Then after upgrading to 7.1.1 I hoped for it to go away, as it didn't, I did a factory reset, configured everything new. Still the problem persists. I then chatted with Google Support, did another factory reset with wiping everything through recovery first. After that I still had the issue, at 10 - 15 % no luck, the phone will just die.
So I contacted Amazon.de (from whom I've bought the phone). They just send me a new one, that I've received today. So new phone, new luck. After turning it on, it showed roughly 30 % of battery. The Android version is 7.0, while I was installing everything (and downloading 7.1.1) the battery dropped under 20 % and BOOM the problem was there again. Now I am getting really annyoed, but I couldn't turn the phone on, as a red light was blinking and nothing happened. I've connected the phone to a charger, waited a few minutes: Nothing, still red light blinking on the top left corner.
I've searched here a little and someone suggested trying to press Power Button + Volume Down. The phone went into Bootloader and then i pressed Factory (I was thinking about factory reset as I was really annoyed). The phone started, but I have now to strange menu entries (Project Menu and MMI Test).
If I click on MMI Test the following pop up appears:

Warning
Battery level is not between 55 and 80, current level is 5, please check!
[Confirm]
If I click on confirm it goes back to the screen before. If I press on the notification MMI Test again, the pop up comes up again.

I tried this with my "old" Nexus 6p, and can reproduce this error. So I guess there is something wrong with both phones. Can anyone with the suddon shutdowns between 10 - 15 % also reproduce these steps? Is there a way to fix this error message? Sadly nothing I've searched for provided any hint. This message seems completely new.
For anyone who wants to try it:
Shut down the Nexus 6p
Go into bootloader (Press Power + Volume Down for 3-5 secs)
Search for factory with volume down, select it with pressing the power button
Wait for it to start, and then click on "MMI Test"
The pop up should then appear
Seriously, I'm completely clueless and not sure what has happened here. Remember, the phone is now factory new! I haven't had it with me for more than 2 hours!
Did any body have any idea was is going on with here?
Selecting "Factory" from bootloader boots into a diagnostic mode. It's used to test aspects of the device if you send it in for repair. Whatever test you're trying to run must require a minimum amount of battery, so when you're trying to run it - it gives you the error since the battery isn't above the required threshold. Like for example, if I factory reset my Android Wear watch, it won't let me pair it to my phone without 80% battery. It'll just pop up and say Please charge to 80% or something like that. With the phone charges some more, you won't face the error since the battery will be charged.
Sucks to see this many people with your issue, though. I actually found an app from the 6P subreddit called "AccuBattery" which gives an estimate of your overall battery health. I've had my 6P since February 2016 & my health is reported at 93% after using the app over a week and 7 charges. Looks like I got lucky.
So Sunday night, my phone as at 34% charge, I went to plug it in with the same Samsung charger I've always used and I noticed a moment later it started to re-boot itself. Found it odd but then it was stuck at the white "T-Mobile" screen for some time, and I removed the battery to re-boot and this time stayed at the Samsung screen. Following troubleshooting tips, I removed the battery and held the power button down for 30 seconds, replaced the battery and tried to power on and now it won't do anything. No boot, no load, no power. Unable to even use recovery mode. I tried 3 usb chargers all with no sign of life on the device.
Thought perhaps the battery was shot, went to two t-mobile stores who were no help, eventually went to a battery/phone repair store and tried a new battery, still nothing. The person said it could be a board issue or software problem (but they did not test it other than putting a battery in.)
Is this thing bricked now? Or are there any options I may have to repair/recover anything on it.
Never rooted or anything, stock S5 with the push updates from t-mobile and such.
So. My phone has this problem, and its pretty weird (IMO). It is possible that it is a hardware problem.
I going to work and I dropped my phone. Didn't think much of it. The phone worked fine for several hours. It started around 40% and only declined somewhat, until about 2-3 hours later where it dropped rapidly to 6%. It was in my pocket when it dropped. I figured at the time that I had just forgotten to turn the screen off, so it drained much more battery. I then plugged it in, and it charged for a little while on a non-turbo charged cord, getting to 21% (which is what it said when it was off). After I turned it on however, it was only at 12%. I didn't bother with it at the moment, but after about 5 minutes it dropped to zero in about 5-10 seconds from when it started dropping. This was concerning, but I had to go back to work so I plugged it back in. When I came back and rebooted it showed 11%, and it stayed at 11% for several hours while I was using it, even though I wasn't charging it. Then randomly it dropped super quickly and died. I turbo charged it overnight. In the morning I booted it up and it immediately shut down claiming there was 0% battery life. It will not boot up without being plugged in. This goes on.
Usually, I charge it for a while and it will give a higher number than it will say when it boots up. It sticks at that boot up number for longer than it should, then dies rapidly. Occasionally it will boot up to be 0% and immediately die. I have tried turning in on and off again (without it dying) and it wont turn back on claiming too low of power regardless of how charged it said it was before. I have tried various charging cables and wall outlets. I have tried several battery repair apps, which did nothing. I was going to try and do a root version, since I figured that would be better but cannot root it. (Using adb to sideload comes up with an error (signature verification failed), trying to flash twrp fails (pre-flash validation failed) and normal root methods fail.) Oh yeah, and I've also factory reset it a few times.
So it seems to me that it's a software problem, namely the battery driver, since it appears to be charging and holding a charge for the most part, but then shutting down randomly due to the driver saying it is at 0% battery life. Alternatively, it could be a problem with the battery or charging port, although nothing seems to be wrong with the charging port visually.
Also potentially of note is that my normal turbo charger, when plugged in, puts a lightning bolt icon in the battery symbol, but on battery usage it says not charging. This could also be the chargers fault, since it had begun to fail previously (only working at certain angles) but it worked earlier the same day and now doesn't.
I didn't install any new updates to the OS or installed any new apps before this occurred either.
Any idea whats going on and how to fix it?
EDIT: I've been trying to look up and see if there was a driver or something for the battery that I could reinstall but I couldn't find anything. So, I ordered a replacement battery of Amazon. Now the question becomes will that fix my problem if I replace the battery?
Think so this might solve your issue ,but getting it checked before ordering would be wise.
Going through your rooting steps , i didnt see that you unlocked your device thats why you are getting errors of signature verification failed.
There is no separate battrey driver for Android its the part of OS itself so you dont need to mess up with that area
Uh... yeah well, Droid Turbo 2's can't root. It wont work. The bootloader is locked up tight, even if you select it in developer options it does nothing.

HI,
has your problem resolved after replaced the battery?
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
