[Q] Faulty Battery, or Hard Bricked? - AT&T LG Optimus G

Hello everyone. I have a problem and I need some of that friendly XDA assistance.
I have been using the AT&T LGOG for about a year now, and have it rooted, unlocked, and flashed CyanogenMod.
I left my phone to charge, plugged into the outlet. When I unplugged it, the screen failed to turn on, remaining black, but the soft keys lit up. I pressed the power button, but no response. Then the soft keys back light went out. The phone, I guess, just shut off. So, I tried turning it on. Instead of the usual Google bootloader logo, the screen remains black. I hold the power button, and nothing happens.
So I plugged it in, and tried turning it on again. The red notification light on the power button illuminates solidly for a couple seconds, then steadily flashes. I have encountered this before, so I know I have no battery and leave it to charge. After an overnight charge, however, I try turning it on again, but am greeted by the same red flashes.
I've tried charging it with different chargers, cables, plugging it into the computer, using different usb computer ports, all with no change in results. When plugged into my computer, it shows up as unknown device, but when i try turning it on, as the notification light flashes, it changes from unknown device to hid compliant device in device manager, but back to unknown device if i let go. I have tried putting it in download mode, but the screen does not show a trace of life. LGNPST fails to detect the device.
I have searched and found in other threads similar occurences. I suspect the battery is at fault here. But before I do a battery pull, I want to make sure I have tried everything else. I cannot RMA it as it is out of warranty, has a large crack on the back, and has a custom rom.
Assistance is requested and appreciated!

The problem is it had a kernel crash, what you need to do is get a torx screw driver, i recommend buying it at sears they have a small screw driver with changeable screws for like 3$ they come in different colors, open the phone & then you will see the battery they have some screws in it as well, screw them off & un-plug the battery gently as the cable is pretty fragile, then plug it right back in; the phone will turn on
hope it helps

Eh?! Photon won't turn on anymore. White LED when plugged in?

My photon was on 5% about an hour ago... then it turned itself off. I plugged it in to the charger and a "white/faint yellow" LED comes on. Normally the photon doesn't have a charge LED so this certainly struck me as odd.
It has been sitting for almost an hour and still won't turn on.
I took the battery out and reconnected the charger and the white/faint yellow LED comes back on, even with the battery pulled out.
What is happening here? Has anyone seen this?
I've see green/orange/red LED flashes for diff things but never white.
Well I found this thread: http://forums.androidcentral.com/sprint-photon/107931-led-not-working.html#post1147045
Looks like white means very low battery and charging. Now the white light has gone off while plugged in... But it still will not turn on
Turns out, I was plugging it into a PC usb that didn't have the drivers installed. The phone won't charge if the moto drivers are not installed, regardless of the light
I plugged it into a wall charger and viola... its back and running.
False alarm!
Lol, exact same thing happened to me! I totally freaked out, but plugged it in a wall and started working.
same thing happened to me yesterday. I plugged into the wall, NOTHING. I started freaking out, until I pulled the battery and re installed it. LED charge light then came on and all was good. Weird.
Can someone help me i have a photon also but when i plug it up it says failed to boot 2 starting rsd mode battery too low to flash and it wont boot up when plugged up to a computer. also when i plug it into the wall it just boot to the m sign

- Pull battery
- Put it back in so it's off
- Keep it plugged into the wall to charge it
- Once charged, power into RSD mode (power+vol up)
- Plug into computer and start RSD and flash 154_5 SBF to get back to stock
- then flash 198_7 SBF for good measure.
- Reboot
When i try that nothing works, it just stays on the white led light
I just bought mine from best buy and it did the same thing..they exchanged the phone since it was defective..

Photon won't turn on anymore. White LED when plugged in
i have a refurbished replacement photon from best buy geek squad that i got last month. within a few days it was acting strange and randomly/often turning itself off. the battery was fully charged yet the unit would often times power down. this happened a lot the first few weeks. then last week the issue seemed to stop and it stayed on 24/7 as i charged it frequently. all was well until yesterday.
i dropped my phone from about 2 feet. the phone turned off and only the "m" boot up screen appeared after i powered on, then it went black. i had a fully charged battery in the unit when this happened. i plugged the charging cable into the phone and it kept booting up to this static "m" screen then turning off. the LED notification light went red and after numerous times powering on and off and resetting the battery (and sim card) i finally got a "5%" battery screen. a few seconds later it showed 100% battery then kept rebooting to the static "m" screen and shutting off again. then i started getting a "?" screen for the battery a few times and back to the 5% and it changed to 80%/100% very quickly and back to the blank screen. i left it plugged in overnight.
now the LED notification light turned white and the phone cannot be powered on. i tried another battery without any success so that shouldn't be the issue.
any ideas what to try next?

Try to fully charge your battery using portable battery charger.
When battery full charge, try to entering recovery mode. From off condition, press both power and volume down, press down until you find android recovery and press volume up button. After you see exclamation logos, press both volume up and down. Then select wipe data. Hope fully you can still entering recovery mode.
If you cannot enter recovery mode, try to enter RSD protocol.
step is, connect your photon to PC using cable data, press both volume up and power, wait until it show RSD Protocol, than flash it again.
How to flash using RSDLite is in development section, you can read there.
Hopefully its can work

[Q] HELP! Atrix does not power on!

Ok so I was at work listening to music when my phone froze. Pulled the battery, which was only at about 85%, and tried to restart. And, nothing. No green light, no dual core screen. Tried four different chargers, including OEM Motorola charger, and tried hooking up to my home PC. Only thing that happens is when I hook up to the PC without the battery in the green light comes on. Power button still doesn't turn the phone on. Just turns off the light. I tried to search, but the closest I found was people stuck at the dual core screen or people who didn't realise their batteries were dead. If it helps, I'm unlocked, rooted, and running GingerMod 2.3.6. Any help is appreciated! Thanks!
Sam issue
I am having the same issue with my wife's phone. We both have Atrixes and I have tried swapping batteries and her battery works fine in my phone. I still can't get it to start up. No green light when plugged into the charger but a solid green when plugged into usb on my PC. How did you end up solving your issue?
I got this problem once. To fix, pull battery out, plug in wall charger to phone (without battery), should boot to the battery with question mark icon, plug battery back in.
I work at a cell phone repair store , and from reading your symptoms I think you might have an issue with the flex cable running your LCD. In the atrix if you drop it there is a possibility of shaking the flex cable off your board, and its a matter of micro soldering or just connecting the cable. I DO NOT suggest doing it yourself. If you want it done professionally call my work. 6053350411

I solved this problem with wall charger
Will anyone here elaborate how to fix it again?
If I plug it in wall charger, no response and no light.
If I plug it in USB, green lights on without battery, no light with battery.
In any case, pressing the power button cannot power on the device.
Please help. Thanks.
Sounds to me like your battery is having issues. Maybe try getting a new battery?
Thanks for your quick reply. I have actually got a new battery already. Still the same behaviour.
Then I can only assume it's the phone. Perhaps the charging circuit. In any case, sorry but I have nothing to recommend. :dunno:
If the plugging it into the wall without a battery in it didnt work... then try waiting for the phone to boot (assuming that it still is and the LCD is disconnected) and swipe where the unlock button normally is, pressing volume up or down, or perhaps try ghosting to adb and run adb devices in the command line... or simply try calling it lol. Also a good piece of information to get... does the backlight come on? If you can prove that the phone is in fact running, then it is most likely the lcd cable as someone said...

Thanks for your advice. I didn't drop the phone before it went to "no-response" status. I just put it on a HD dock for charging and the next day it doesn't boot anymore. I have put in HD dock for charging for a few weeks already.
My phone doesn't boot at all. I don't see any backlight or any special response. Or It does something that I don't know. I tried to plug into USB after pressed the button. If it's on, the computer should detect a device, right?
Any ideas are welcomed, i will try all.

S3 suddenly wont turn on, bottom lights and charging led work

Hi All,
I was out a couple of days back and my battery died. No trouble, come back home and charge it up. Worth noting that in recent months battery performance has been poor with a full charge only lasting about 8hours or so. I put this down to a new ROM I flashed as well as natural deterioration (18 month old S3).
Plug into the wall, red charging LED comes on, but the battery splash screen does not. Tried another charger...same. Thinking nothing of it I go to bed and wake up next morning to be greeted by a green charging LED. However, still no battery splash screen. I try to boot...it doesn't. When I "power on" the bottom LED buttons do light up white and go off after a few seconds. When I press the hold button again, they also come on for a few seconds. If i press the hold button while the button LEDs are on, they go off.
This makes me think the screen has broken as both the hold button and the charging LED is doing what it would do...but without any screen activity. However, it was not dropped or put under any pressure in any way. I have opened it up and also made sure the ribbon is undamaged and connected properly. I have tried calling the phone to no avail. It also does not vibrate or make any noises. Perhaps the battery doesn't have enough juice? Its as if its on the battery splash screen, I just cant see it.
I should mention the screen is infact cracked from an incident about 6-8 months ago. It was however, fully functional. Presumably, this will unfortunately stop me from sending it in. It was also using a flashed rom (CM11) and a flashed kernal (Boeffla).
I used a multimeter and measured 3.96v across the battery so that's fine. I can't test the current as I cant break into the S3 circuit and I dont have a resistor on hand to put some load on it.
Next steps?

Try to put it in odin mode (power+vol down+home then press vol up to agree that you are now in odin mode). You should see it in odin.
If you dont see it, your battery or energy system of your phone is broken. Otherwise your screen is probably broken?.

I've managed to get it into download mode and too show up in odin. I can also get it to show the files in Windows if i wait after holding the power button.
This all indicates it is in fact booting up and the screen is broken...
...BUT...no sound...no vibration...and no calls received
Its as if its only half on. Beginning to suspect a catastophic motherboard failure. Is it possible the battery is at fault? Its as if a whole power rail providing for the phone receiver, loudspeaker, vibrator and screen has gone.

S6 - Bricked - Black screen and Solid White LED

Hello, friends
Out of the blue, my S6 Edge tried to restart, but got stuck in a loop at the Samsung Logo. One or two times it went to "insert pin" and then restarted again. I tried to Force Restart and it didn't solve the problem.
After a few tries, I managed to wipe the cache partition. Now it's simply bricked with a black screen and a Solid White LED. I can't restart it, enter download mode or safe mode or anything. Odin doesn't recognize it at all. Is there anything I could try?
The phone is not rooted.

Thank you! Tried it. Doesn't work. It's beyond my understading why would it behave this way after I managed to clear the cache. At least before that it went into download mode or safe mode. I still suspect a software issue.

So vol down + home + power will not get you to download mode?
How about recovery? Vol up + home + power?
This happened to me before and the way i got out of it was hold only vol down + power as soon as the screen went off completely (no led lit) switch to download mode combo.
Tried both of the commands. They didn't work. I will let it drain the battery completely and then see what happens.

reminds me of the bad emmc memory like the note 4s had.
some times completly letting the battery drain can fix it being "stuck". then recharge for 20 min or so then trying to turn on.
if u plug it into pc does it reconize anything in device manager
even unknown device or descriptor failed anythiing at all?
This morning the LED was off, so I tried to recharge it. Nothing happens. Also, the PC doesn't detect it at all. I think it's safe to assume I need a new phone. Too bad...at least if I was able to recover the data on this.

you can thank sammy for no ext sd card for that one or more than likely pics would be on sd
now one last sollution is to try buying a cheap battery my note 5 had a issue it shut of one day and wouldnt do nothing i understand ures was blinkik and trying at least
so its a leap but last resort
same problem here started over a week ago - samsung S6: black screen, constant white led. tried all variations of resetting with buttons. over a year ago i replaced the battery, and its been fine since. when this no boot issued happened i also tried changing the battery to a known good one. on inserting a battery and then pressing the power button the indicator led will go to green for less than a second before changing to constant white, and it stays that way no matter what until the battery is drained or the battery is removed. Strange thing is there is no information from samsung on what this behaviour means, but I've come across dozens of other S6 owners on the web with the same problem, so this is obviously diagnostic behaviour designed by samsung - but no info from samsung. the phone has never been damaged or watered or rooted so I'm at a loss.
Confirmed diagnostics:
The phone will respond to the power button and attempt to turn on
The phone will charge a battery, so the charging circuits and battery circuits are working.
The phone does not get picked up by a Windows 10 PC with Kies installed in any state - other samsung phones get picked up no problem.
Same here
I have the same symptoms. When I hild the vol up+home+pwr I get a green let for 1/2 sec then white. No other combinations do a thing. I swapped the battery for a new one. No luck.
Mine started a few days ago. The phone was 50% charge and i plugged it in for two hours. Came back and it had a solid red led. After a few hours the red light went off. It was then 100% unresponsive. I then took it apart and disconnected the battery. When I reconnected it, it started to do the white let thing described above

I have one that behaves exactly the same I changed the battery and didn't make any difference. my next step is to replace power management chip. I'll let you know.
Any luck on this?
Mine has been like this for a couple months, kind of gave up on it, but decided to give it a go again!
Same problem here, just happend after switching the battery. Anyone have solved this?
I found a kinda solution, plug your charger in and charge past 30% then unplug charger. then use just vol down and power button for 7-10 seconds, after 7-10 seconds just release the power button while still holding vol down button until you see samsung logo, you can tell if you did it wrong by the solid led being back on, repeat until success, once you have it on do NOT press the power button or it will RESET back to solid led/black screen.
I have the same problem with my s6 active and similar story to dbeeheim. Has anyone fixed this? And can anyone confirm that enzo13's solution works?
Much thanks in advance!!
i have same problem!
Suddenly my S6 dead, battery was ~80%, no charge
yesterday i try to change battery, after that if push power button, LED small light comes but in white with purple, then stuck. (it's small Notifications LED)
and i chnge the screen, but no more than white/prople LED.
(no any thing on screen, always black..)
what is the problem?
i think it's battery because it last month didn't work good, and it's old 3years battery.. but no idea..
Hello guys my Samsung S6 sm-g920f has the solid white led and black screen. Really no fixes?
thank you
Same issue
I have the exact same issue. My Galaxy S6 Edge (G925F) suddenly died and won't get past the 'Galaxy S6 Edge Powered by Android' screen.
I am unable to reach the recovery options. I've tried flashing two different stock ROMs with Odin which succeed but without successfully turning on my phone. I've also tried flashing TWRP with success in Odin but it won't get past the 'Powered by Android' screen before turning off after +-4 seconds. The white LED is on even when the screen is black.
Just had this same issue, my battery died and I forgot to charge my phone overnight, woke up and it would not turn on, black screen. I did manage to replace the battery and do several diagnostic tests on it. My battery was receiving about half the power output it should be (this is normal it's a 4.5yo phone) and when I replaced the battery with a new one, it did not turn on. With wireless charging I can tell I am receiving a charge and with standard I can not. The screen does not indicate it is charging with either method but my wireless charging pad lights up indicating my phone is being charged. I think it may be the processor or screen itself. This really sucks because I lost all my data on my phone and data recovery can be over $500

Xperia Z5 Compact fully charged but not turning on

Hello,
My phone's battery was starting to have issues so I bought a new one and replaced it yesterday. I've done it recently on another phone (same model) so knew what I was doing when reassembling it, with the right adhesives and everything. Then I left it plugged for the night as this was advised by the new battery's seller. But this is what happens this morning when I try to turn it on:
- Phone doesn't vibrate when pressing the power button, neither when holding different combinations of Power + volume, etc.
- When I plug it this is what happens: imgur[dot]com/fByubwN The screen turns on as it would normally do, displays the 100% charged battery logo and then just dies (with the green led remaining). The only way to turn the screen on is to unplug and plug it again. But the phone itself isn't booting.
Any thoughts appreciated!

I'd say that the battery is at fault. It can be two things:
- it is not correctly plugged (maybe the connector is not perfectly aligned, or one of the pins is bended)
- it is completely depleted, so won't charge at all.
Disconnect phone from charger and try to test voltage on the motherboard with a voltmeter. If you can't read anything, disconnect the battery and test it directly.
Personally I would say the first problem is more likely - a completely bricked battery is not that common.
Actually the battery was fine. I've opened it again and turns out I've kind of messed up with the flex connectors of the motherboard.
So I was able to boot it while it's open but as soon as I reassemble it, the controls are not detected anymore. It's a matter of millimeters, some parts probably don't sit properly, etc.
We spent some time on it with a guy at a local repair shop, the conclusion was that I had to get a new phone, or a new motherboard which is almost the same haha.
Thank you for taking the time to reply!
