[Q] Help! LG G2 wont turn on at all - AT&T LG G2

I have a big problem whit my LG G2 D800. Phones worked flawlessly since the day I got it, and I've had zero problems with it at all. This morning i restarted it, and it didnt turn back on ever. I tried plugging it into a different outlet with a different charge for an hour, tried vol- power and holding power for 5 minutes. it looks like the battery is dead. I apologize for my English , and appreciate your help

I had a similar order of events
A similar thing happened to my G2 as well on April 8th. I held the power button down, selected power off and restart, and it didn't come back on. I tried everything I could think of. Button combos while unplugged/plugged in (AC power and a USB port on a PC), physically pulling the battery, etc. I took the phone apart entirely to check connections and to inspect the board and had my IT instructor do the same, nothing seemed wrong. Also, my LG-D800 was completely stock and not rooted running the latest OTA update from AT&t.
Did you select the same option to restart? Or did you power off then hold the power button to turn it back on? I find it strange that there is another occurrence of a similar (or same?) order of events that caused the G2 to just die. I searched all over and couldn't find a similar story.
I ended up sending mine to LG since the logical conclusion was a dead board. Sorry I don't have an answer, but I thought sharing my experience could help with troubleshooting in some way. I'll update with information if LG gives me any specifics.
UPDATE: Nothing more than "bad component caused by physical or water/liquid damage" from LG, unfortunately. My repair will cost about $70 which isn't too bad. You may want to see what LG can do for you. Good luck!

How To Unbrick Nexus S? Need Urgent Help.

Dear Geeks,
I need your urgent help/advice. i'm three weeks far to my wedding and have a lot of troubles to handle, of course i need this phone.
let me describe the matter i have.
My nexus s is not booting, not starting, nothing.
what i did?
Last night, power button stopped working. I have experienced this 4-5 months ago. I don't know why, the problem has been solved by itself after few days later. i did nothing at those days. the power button came back. (as to my opinion, this is happening due to software problem) Anyway, i have used the market and installed ''fix power button'' application to use volume buttons for opening the screen.
I slept and when i woke up, i saw that phone needs to be charged but i waited. there was %11 something. i tried to handle the power button, pressed many times on it, thought that it may come back again same as 4-5 months ago it happened.
I removed battery and replaced again. i tried this many times. removed, replaced, used the usb cable via AC charger and phone started but there was no result. power button still was not working.
i thought that if the battery runs out, and then, when i charge the phone, maybe this matter may be solved. (ok this was stupid idea)
phone started to charge. when i plug the usb cable, phone was booting and displaying the google and animation and later it was ok to use.
meanwhile i keep on removing battery and replacing battery while the usb cable connected. but when phone starts to boot, i removed battery and replaced again. phone was ok, it was booting. few times it was booting.
but baaaam.
it is now not starting not booting, nothing.
now, when i replace the battery, phone is getting hot, especially sim-card area. i m removing the battery and connecting the usb. same again phone is getting hot, same sim-card area again.
i have waited enough not to connect the battery or usb charging cable. but no result.
what can i do now? what are your opinions?
my opinions/guess:
-i am using 3500 mah lithium polymere battery. maybe the battery died. i m using that battery more than 1 year, around 15 months. i dont turn off wi-fi so i m charging phone everyday.
- phone crashed during booting. and now the phone is totally brick.(i dont wanna believe this, this phone can be usable, believe me i feel it i think whatever happens, this phone can be usable via software installing or rooting... of course if you dont throw it towards a wall etc.)
by the way, my phone was not rooted. no time to root these days. and of course the phone was not starting.
what is your idea? what happened phone? what should i do?
if you reply, i will be appreciated.
A big advice for people reading this, dont remove the battery when your phone is booting.
I hope someone has a solution, since I have the same probelm...
I searched everything and tried every tool in this forum, but no success...

dude, unfortunately those solutions not working on my device.
when i connect charger and i replace the battery, within seconds phone boots itself without power button. it should be this way. removing and replacing the battery helped me to start to boot.
i sense this case a bit different from that solutions.
i need to try with a different battery. my wife has nexus s also. she is very lucky she has no problems i have experienced so far. i will try with her battery.
i think there is a matter with mainboard.
by the way i forgot to say that i dropped my phone last evening. just after then phone was acting that i'm pressing long onto power button. and power button finally stopped working when i remove the battery.
i think this is happened because of dropping the phone from my belly high.
but the last thing i have done which removing the battery while the phone is booting, i wish, i should not have done. i could use it without the power button.

If you have not rooted your device, you should have you warranty, right? Take the phone back to the carrier, and tell them about your problem. o.o Sorry, I'm of no help, but you're in a horrible situation. Wanted to at least give a little help.
Same exact problem here.
2nd of August - mom's phone turned of and just would not boot or prompt at all. The modem heats up when power is turned on or connected.
Tried
The unbrickable methods (but the computer would not detect the device in any form)
A JTAG - I was able to write the recovery and bootloader - assembled the phone and it just won't boot or prompt
Need to try
Another battery to see if it solves the issue.
Removing the xOM5 resistor and converting to a development S5PC110
Tried another battery - no luck
Did the resistor removal and converted to a dev board - Unbrickable now detects the board!
trying to get the device into fastboot - will update

I had the same problem few months ago. Power button had died. While I was able to boot with remove battery and connect to charger option and I was rooted. But after a week I decided to take the phone to Samsung service center to get the power button replaced. My phone did not have warranty. Samsung took few hours to get the power button replaced and it costed me about $7. I think that's the easiest method. They did not have a stock of I9020 power button, so they fixed a I9023 power button.
Any update? I'm curious to see if you get it working. Had the same happen to my NS a few days ago and would like to see if I can get it going again so I can give it to my stepson.

I've given nexus s to samsung service. Actually, power button may be handled by replacing with new one, but with no hope, it will not come back when i read messages about mainboard failure. I will update news whenever it's possible.
we'll see.
I would like to hope it is kind of software matter.
Pls god give my nexus s back, i got extended 3500mah battery.
grrr....

So with the hardware mod - instead of selecting Nexus S -> I tied the Galaxy S in unbrickable - first time I've seen the screen alive! - puts the phone into download mode and I can disconnect from the usb and it stays in download mode! .. when i tried to flash odin I get a "There is no PIT partition" error -> this ofcourse is with re-partition and bootloader update UNCHECKED
When I tried Heimdall it wouldnt let me flash without a pit file. So trying Heimdall 1.1.1 - I get Failed to Access device Error: -3
Any chance some one with an i9020T can do me a huge favor? Use Heimdall 1.3.2 - download your PIT file and upload it here?
reaching for string ends out here :/

The power button had to be replaced. I shorted the connection when ever I had to press the power button during the boot sequence. That's how I fixed mine.

[Q] HOX Won't Turn On with Sporadic Red LED

Yesterday, I was using the Navigation app on my phone. It was a busy day, so I think I had left the app running. In my previous experiences with the app, it stays on until I exit the app. Previously, I remember the phone running really hot.
Anyhow, yesterday sometime in the afternoon, I took my phone out and found the screen off. Pushing the power button didn't do anything. So I figure it probably had a drained battery and I plugged it in the wall to charge. About three or four hours later, I pushed the power button again - just to turn on my phone and see if I had any missed texts/calls. Nothing - the screen didn't turn on, but the red LED light was on. So I left it charging through the wall adapter, and went to go do some research about the problem.
Next morning the red LED was flashing. I tried the power button again, but nothing happened. Then I got a little panicky and tried the different button configurations I had read about: holding down the power button for x amount of seconds, holding down the power button and volume down button simultaneously - but again, nothing happened.
Fast forward to tonight - I'm not sure if my phone is charging or not, or if something else sinister is happening to it. I pushed the power button down about a half hour ago, and the red LED turned off. I then, plugged my phone into my computer, and I got a dialog pop-up that said "Device driver was not properly installed" with the driver name "qhsusb_dload".
Any idea what this issue is? Or could you point me to further info somewhere?
Any help is much appreciated!
PS. I got my HTC One X just about 2 and a half months ago at the end of November. My phone isn't rooted, and the most "advanced" thing I did with it was put ADWLauncher on it.

qhsusb_dload usually indicates a hard brick. take it for warranty repair. given what you've described most likely you've had a hardware failure of some sort.
Sounds like you've ended up in qualcom download mode somehow. When you held down power and volume down, was you're phone plugged in? I think I accidentally made it to qdl mode once when my phone was plugged into the wall. Try unplugging power, and press and holding power and volume down, see what happens.. Otherwise you may be able to get help from 18th.abn who seems to know quite a bit about the qualcom download mode. Good luck.

It pains me to read your post because I had the same exact thing months ago. The phone turned off while using navigation and never turned on again. At the time JET didn't exist so there was nothing I could do about it.
Look here and see if it might help your situation and maybe avoid a warranty repair
http://forum.xda-developers.com/showthread.php?t=1982442
I've seen this type of post a few times and makes me think that there's definitely something wrong with the evita that's bricking these phones all on their own. Maybe hardware like someone else suggested so maybe warranty repair might be safer.
Best of luck. :thumbup:
Thank you all for your help and suggestions. It appears my phone is dead, completely. I had high hopes, but now I think I'm wasting energy. I called HTC and they said they'd send me an email with ticket info to return it so they could fix it. But they never sent the email. Now I must chase after them and try to get them to fix my phone. Sigh. I would try JET, but I don't run Linux and don't think I'm as tech savvy as I should be to set it up.
Thanks again!

IMO, if you are bone stock (sounds like you are) its not worth it to mess with JET. Just send the phone to HTC (or your carrier, if they handle warranty matters - they are often easier to deal with than HTC). It may well be a hardware issue, that JET won't fix.

Yea... if you are in qdl download.. sounds like a hardware failure..sending it back to HTC might be the only way to go..
Up and running again, but w/ new phone
Yup, I took it to my carrier (ATT) yesterday and they couldn't do anything with it, so they gave me new phone right there and then, which was great news. Bad news is I have to start from scratch. But at least I've learned to back up early and often.
Not sure if you could have done anything about this as it seems to be a hardware failure

[Completed] LG G2 No power...Constantly Vibrating

Hey everyone 2 weeks ago I was using my lg g2 verizon model running android 5.0.1 lollipop and it felt from my bedside. Note this is not her first time the phone had fallen. I have a tpu case on it and it usually fears very well against occasional drops. That fateful night however the phone fell and when i picked it up it went blank and was switched off. I tried to power it on by pressing the power button but the phone just vibrated continuously on a second by second basis ( literally counting mississippis). I then tried to plug the phone into my wall outlet to force a boot but it just vibrated too.
Later that week i opened it up removed and reattached the battery cable and IT CAME ON!! Two short days after i rebooted the device for a new app but then it didnt power on. The same problem occured. I tried my fix again and after a couple of tries it finally worked. A week later and forgetting my phone problems i restarted ny phone again only to find out that the problem had returned. After trying my quick fix over and over again, nothing seemed to work so i decided to try troubleshooting the device myself. My results have left me baffled.
Ok so before you guys start shouting out solutions, heres what did and found ;
1) Tried a new battery and the phone still vibrated.
2) Unplugged the battery from the motherboard and plugged in my charger and the phone still vibrated. Lead me to believe that its not a battery problem.
3) Removed all un-neccessary components from the phone ( camera, screen, mic, antennas, etc...) the phone still vibrated.
4) Removed the power button module from the phone and it still vibrated when the charger was plugged in.
Note: I disconnected the vibrator behind then motherboard and held the phone to my ear while I plugged it in to my wall outlet. I could hear a faint clicking sound in a cycle.
Im completely lost sorry for the long thread but if anyone can offer some advice please help me i have no money to buy a new phone atm #life
Thank you in advance xD

Hi and thank you for using XDA Assist
Unfortunally for your phone this is indeed an hardware problem and i doubt it may be a software one...
If you didn't "worked" on the device from the software side i think the better way is to take it to an assistance shop or something like that in order to fix your vibration problem.
But for futher assistance i suggest you to ask overe here: Android Q&A, Help & Troubleshooting
Or here:

Good luck!

S6 100% unresponsive with irreplaceable photos contained within... need options

Changing the thread around to reflect the current situation, new text at the bottom of the post.
While out to dinner with my family an hour or so ago, my phone suddenly stopped working. I had been checking some emails when the food arrived, so I pressed the power button to shut down the screen and set the phone to the side. About 30 minutes later, I tried to open my phone to continue where I had left off, only I got no response at all from the device. I immediately tried the normal troubleshooting actions (holding power button for 30+ seconds and attempting to go into recovery mode), but still got no response from the phone. I have since tried charging it at home with it's original quick charger, but even after 15 minutes on the charger, there isn't even a red light indicating it is charging. Is there anything that I can try to fix this on my own, or is it likely that I've got some technical fault that only Verizon can deal with?
Thanks.
PS: I'm 100% sure that no liquid came in contact with my phone during dinner. Even if I wasn't so sure, both the phone and case have been bone dry through the entire ordeal.
New situation:
The "techs" at Verizon were less than useless... While there, they tried fewer fixes than I was able to attempt before telling me that the only option they could offer is to replace the phone. The problem, as I've said a little lower in this thread, is that I've got some irreplaceable photos of my recently deceased cat of 19 years stuck on the phone that I never got the chance to back up before this event.
And so now I need options. I'm willing to do pretty much anything, up to and including tearing the phone apart to manually access the memory unit, but the end result absolutely has to be those photos recovered.
Did you do the hard reset combination (Power, Vol Down?) I've had the problem happen to me before. Usually, what happens is it will lock up when it is having memory issues, freeze, then if I'm lucky, it will come out of it. Otherwise I have to do a hard reset.
It hasn't happened yet since I've been on 5.1.1 but I've only been on that for 3 days or so.
Edit: Just in case you didn't know, the recovery combination is Power, Vol Up, and Home when the phone is actually off. When the phone freezes like that and you don't get a response it's still on but completely locked up until you power off the phone.

I've tried soft reset (hold power only), hard reset, and recovery, all to no avail, and holding each for long after it's supposed to respond (at least 60 seconds).
Volume down and power should simulate a battery pull. If that does not work, I would recommend going to a Verizon store.
Give your name to the concierge.
When they call your name, try the Volume down + Power again.
It should work then.

I'm really hoping they will provide more help than that. There are some pictures of my cat on the phone that I had to euthanize last week after 19 years that I never had the chance to back up.

I'm sorry about your cat.
It was more to the point that what doesn't work when you are on your own, will work perfectly when you take it to the technician.
I used to do tech support for phones and tablets. I've seen lots of instances where the customer tries something with me on the phone that they had tried multiple times before, and with me on the phone it works immediately. Try the key combos with it plugged in, with it plugged in to a different charger, with it plugged into your computer. If none of those work, then take it to Verizon.

All of this was done before taking it to Verizon. All key combinations were tried unplugged then plugged into 3 different chargers and also my computer with 3 different cables and several different USB ports. When I went to Verizon, they tried the key combinations unplugged and then tried plugging it in and seeing if it would take a charge... hence the assertion that they tried less than I was able to attempt at home.
Time to find someone who can repair the phone locally. Any type of warranty or factory repair will cost you the pictures.
Sounds like it's safe to say the phone is beyond simple trouble-shooting. I found myself in a similar predicament last year when I busted the screen on my S4. I dropped my phone on some concrete steps and the screen (in addition to being shattered) went completely black, but I knew the phone was still working because I could still hear the person I was taking to on the phone lol.
I ended up replacing the phone through Verizon. They referred me to some third party company that agreed to replace the phone for $100 and sent me a replacement with a box to put the busted one in. At this point I found myself presented with a unique opportunity, given the fact that I had both a working S4 and my broken one.
Because I didn't have the chance to back up the phone before I lost access to it (it's pretty hard to unlock a phone without the screen) I looked up a guide on how to disassemble the S4 on YouTube in order to gain access to the motherboard. The whole process was relatively easy to carry out and I was able to disassemble both phones, switch the motherboards, backup the information I needed, and switch them back.
Sorry for the long-winded response. I realize this is a pretty drastic measure to take and that you may not have access to a second S6. It's also entirely possible that the motherboard on your phone is part of the problem so switching it wouldn't help much in that case (like I said, I knew my phone was still working despite the screen). Just wanted to offer another option =).
I am in a similar predicament, desperate to get my photos and videos back and have been watching your thread for some ideas. My 7 week old Verizon Samsung Galaxy S6 G920VVRU4BOG9, android version 5.1.1. ceased to do anything on Monday for reasons unknown. It is now back on but it has been wiped clean. I had to do a hard reset. Samsung & VZW tech support were not helpful. May I ask what model your phone is? Provided you are able to get yours back on, I'm wondering if you may have some success with some of the following:
Wondershare Dr Fone for Android
Asoftech Data Recovery
Kvisoft Data Recovery
Ease US data recovery.
I could not get them to work because you must first have a rooted phone to retrieve them and mine apparently can't be rooted. I apologize if this is redundant but I thought I'd throw that out there in case you might have a change of recovering those photos. I'm sorry for your loss. It's very hard to lose a beloved pet.

Nexus S [CM11] - hardbricked, no vigration, no computer detection!

My phone: Nexus S, 16Gb, Rom CM11, Android 4.4.4 (List of updates: https://download.cyanogenmod.org/?device=crespo)
My story
Yesterday, (about 9.00pm 13/12/2015) my phone got some laggy, so I powered him off. I left it there, 15 minutes later I came back, and I forgot that he had been powered off, so I thought it was just sleeping. I picked him up and press PowerButton. Nothing happended!
Then I got a look at CM rom, found that interesting is my Rom just got a new update at 2.00pm 13/12/2015. I think that my phone has auto-updated!!
In the past, sometime he behaved the same: PowerButton not respond. So, after that 1st press, about 5 sec later, I started to press the PowerButton repeatedly and rapidly, hopefully the phone would wake up.
But no, the reality was that he was being off. There were about 6-7 presses, I will describe slowly below (assume between each press is 0.2 sec):
1st and 2nd press: nothing happened
3rd press: the phone vibrated, and Google logo appeared
4th press: (I had no mean to continue pressing, but it was too fast, I couldn't stop) suddenly, the Google logo disappeared (so the logo stayed on screen just for about 0.2 sec; while normally, it should stay there for atleast 5 sec)
5th and 6th press: nothing happened!
And from then on, no more, anything happened.
What I tried
Hold PowerButton for even 1 minute: nothing happen!
Hold PowerButton + VolumeUP for even 1 minute: none!
Hold PowerButton + VolumeUPandDOWN for even 1 minute: none too!
Connect to charger (wall or pc): no Battery Animation show up! BUT the phone and Battery get warming up!
Take out the Battery for even 15 minutes, then put it back, and PowerButton: nothing!
And the phone not get recognized by PC too.
Sumary
No display
No vigration
No recognized by PC (because of this, I can not follow this method: http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732
More Information
In the past, the VolumeDOWN sometimes seems get stucked, cause the phone silent and auto boot to safemode, after many try to press and reboot, the phone may get out of safemode (because VolumeDOWN back to normal)
PowerButton sometimes not respond.
My Battery is not good, sometimes it drops too much! Eg: having 50%, after reboot, dropped to 3%, and start to increase slowly, max around 30% and become normally.
Hope you guys have some ideas! I still can't do anything, when the phone is not regconized by PC!!
Thanks for reading!
Thank you!
Hey,
2 things come to mind and I bet are both the problems. First off you need a new battery and you seem to know this, very cheap now a days but still buy a good one as cheap knock offs are abundant and don't support the power they say, try mugen, anker or stock oem
Also you need to replace power button, this phone was always notorious with bad ones, a new one is cheap but many often found just a loose connection so if you open up the phone, check the ribbon connections and then throw in that new battery all should be well, hopefully
Best of luck!

Thank you. I'll try your suggest ASAP.
But I'm wondering, that do you think that CM Update maybe also a reason?
I kind of doubt it as that should only effect the software, if you were getting a bootloop or anything to that extant yeah, but being it won't power on at all I doubt it
thank you
Nope, I've seen these symptoms before - exactly the same thing. Dude, I think your phone is Superbricked.
I've got a stack of 3 Nexus S 4G's that have exactly the same problem - the eMMC card is trashed by a buggy "secure erase" implementation. See: https://wiki.cyanogenmod.org/w/EMMC_Bugs
My "working" one was working great, even set it up to sell on eBay, when I went to wipe its data with a factory-reset from the settings menus. When it shut down to reboot, I pulled the battery. That's what bricked it - because the eMMC was halfway through a background erase/rewrite procedure, it wiped out the boot loader somehow and completely bricked the phone. It now does precisely, exactly the same thing you describe - absolutely nothing, except when it's plugged in, it warms up after a while.
Best I can tell, the only way out from here is to use a JTAG device to reflash the chip, but even then, the eMMC itself might be "unbootable" (i.e. can't start up, can't be read or written, can't be reformatted/restored).
I just called it "end of life" for those phones and now they're just a sour reminder on my shelf

thank you!!
my heart just stop breathing :'( :'(
God, I wish there were a solution to it. I'd really like to donate a phone to anyone that thinks they have the tools or skills to make a "how I did it" explanation - involving whatever tools/software are necessary - to bring these phones back and help us all. I bought 2 of those 3 phones as "for parts" on eBay, and it turned out that both of those phones appeared to have exactly this same issue (though one also had a cracked glass). I even verified the issue by swapping in my good phone's eMMC (at least on the NS4G, it's a swappable card module), and the boards booted up. I only needed the one for the good screen (as I had a good board but completely destroyed display panel) - and that's how I got my one working again.
Then, in the end, I accidentally stumbled upon the method by which the previous two phones were bricked - and now there are three. It seems like a fairly common problem. :/
