Dead GFlex2: get LG logo but no startup (or Recovery) - LG G Flex 2

My LG G Flex 2 H950 was working fine, running google maps and playing music, plugged in to the car charger. Within minutes of leaving the car the phone was dead - I could not power it on. I can usually get it to show the LG logo by trying to start in Recovery Mode (holding the power and volume-down buttons for several seconds) but then the logo just disappears after a few seconds and the phone does not power on. But sometimes when I try this the red LED blinks on the phone screen and the logo may or may not appear. Sometimes (50%) when I plug the phone in to my Windows 10 desktop, the computer plays a tone to indicate a new device has been connected, but no icon appears in the list of hard drives or devices.
I think the battery is charging normally - when I connect the phone to a USB volt meter it usually (but not always) shows a normal amount of amperage flowing, and just now when I tried to start the phone it showed the battery charge icon on the phone screen (it doesn't usually do this) and showed 100% charge.
Is there anything else I can try, even if just to get the phone running long enough to backup my text messages etc?
Is there any way to test what's actually wrong? I'd hate to spend money on a new battery or charging port etc for a slim chance to temporarily fix a phone that seems like it's dying.
Thanks for any advice or suggestions...

Hey, i've got the same problem since today. i was watching youtube videos when the phone suddenly stopped working. did you already find the problem?
Sorry for my bad englisch ( Dutch)

No - not solved, phone still dead. Still would love to hear any advice...

I used to have the exact same problem as you - bootloops at the LG logo, no recovery etc. After some reading it seemed that the battery was the root of the problem, and after replacing the battery my phone was back to life - no issues ever since. I recommend you check if the battery is the issue by connecting it to a normal charger (i.e. not charging from a PC) and powering it on, by holding the power button at the battery charging screen. If it powers on normally then it's most likely a battery issue, which can be easily fixed. Cheers!

[HELP] Stock 5.0.1 phone power up issue

Hello,
I flashed the latest LRX22C image on my nexus 5 today.Had flashed it clean,wiping data,cache and system etc except the Internal Storage.Then I flashed the SUPERSU 2.37 ZIP .Everything was fine for about 4 hours.Then suddenly when I pressed the power button to turn the screen off,it was not turning off and the "Switch off" mode was popping up instead .Then, when I got a call,it switched off.The phone won't turn on again.It starts,the Google Boot Splash appears and the bootanimation starts for like 2 seconds and it switches off.Same thing for bootloader mode.
Please Help me!
EDIT: Now its turning on by itself and switches off in 2 seconds!
Sounds like a bad power switch to me, but of course that is just my opinion. :good:
sounds like a mech issue.
legit isue
I have the same problem on mine now... Basically my phone powered down around 45%. Battery. At the time i thought it was dead... But it wasnt. When i would plug into external power, either usb or through wireless charging it would power cycle continuously at the android splash screen.... (1 to 2 second intervals - even if i booted into fastboot) Interestingly it would never go to the battery charging mode. But automatically boot on charge... It did this for about 6 hours then i gave up and left it unplugged for a day. I plugged it back in and it started power cycling again, however this time on its third boot it came back to life . thats when i discovered i still had 40% battery... I dont know what exactly made it boot but it did. Oddly also on boot, it started optimising apps and finishing install again. I checked the md5 before I installed the update so no issue there. Since it powered up i have powered the phone off using the power button long push and let the phone power down. After doing this when i plug the phone in to usb charge it goes to the charge screen. No issue. That said, if i try to power up while tethered and charging it will not allow it. It just stays at the charge screen. As soon as i unplug the usb the power button allows the phone to power up and work... When booted up it charges as normal when plugged in. Im convinced there is an issue with the power management drivers or drivers for the button controls. My phone worked fine until the 5.0.1 update was installed. On my nexus 5. Anyone else or just us two? Ive had a hard time finding people posting on this issue.

Moto G XT1032 - Can access Fastboot, but it wouldn't work - Bricked?

Hi. First of all, thanks for taking the time to read this. I know it's a long post, I'm just trying to be as detailed as possible.
I've a Moto G XT-1032 that stopped working a couple days ago. It has the original battery, original software. It didn't came with an original charger, so I have been using a Samsung Galaxy Tab one. The phone is almost two years old.
This is how it all started: It had low battery. When I got home it connected itself to the wi fi, and tons of whatsapp messages came at the same time. It went off.
I thought maybe it had drained the battery. Plugged it in to charge, didn't get the led on, and the battery showed 0% for an instant. Then the phone turned itself on, got the M logo and then the screen went black (like... some sort of backlight is on, but the screen is just black)
I turn it off, and it goes back on. No battery image, straight to the M logo, and then black screen. I tried holding power + vol down keys for more than 120 secs, finger pain is the only I got. It can access fastboot mode, but doesn't matter which option I pick, normal powerup, recovery, factory... I select them and then press vol up, but it just goes to the white screen with the M logo, then black screen.
When I plug the charger, and go to fastboot mode, it doesn't show battery charging. Just says battery low (or battery ok). When I plug it to the computer via the usb cable, and access fastboot, it shows battery charging.
The computer doesn't detect the device at all. First time I plugged it, it tried to install drivers, but failed. I downloaded them from motorola's page.
If I open motorola device manager, it tells me there aren't updates for my phone... So... I guess it's recognizing it? But I still can't see it. Windows only shows me my C and D drives, but not the phone. Tried different usb cables, different usb ports. Nothing changes.
I sent it to a service, they tested the battery and charging port, they said those were fine. But didn't find the problem.
Any ideas? Suggestions?
Thanks in advance!

2n Gen Moto G Boot Loop / Won't Start HELP!!

I have a 2nd Gen Moto G that was pretty much in mint condition & prior to yesterday it showed no signs of any potential problems. Then last night the screen completely froze & wouldn't allow any input. The phone then shut itself off & I figured it would just restart & be fine. Instead it went into a constant boot loop where it reaches the white "M" animation screen then shuts right back down. I played around with it for a few hours today & did a ton of searching on the internet with no results.
I also should state that the battery did not die when this happened. I mention that because there were some posts where people let their battery go completely dead then they couldn't get their Moto G to power back on, however that was not case for me as the battery had well over 50% charge when this happened.
Things I have tried in order to fix this:
Using a different charger (both wall and USB to the computer).
-Holding down the power button for 7-10 seconds while plugged in.
-Holding down the power button for 7-10 seconds while not plugged in.
-Holding down the power button for 2 minutes or more (while plugged in and while not plugged in).
-Holding down the power button and volume up buttons until the phone starts (while plugged in and while not plugged in).
-Holding down the power and volume down buttons for 2 minutes or more (while plugged in and while not plugged in).
Now this step does bring up the fastboot menu however selecting any option in this menu just causes the phone to back into the boot loop. And yes I know how to access options in this menu (down volume to scroll & up volume or power button to select).
So basically everything just sends the phone into boot loop. Is the phone toast? Also I should mention that all day today it would randomly try to start itself & get to the Moto animation screen & then shut down & that was while it was sitting on the desk & I hadn't even touched it.
If the phone is toast is there any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?
Alright so seeing as no one has any suggestions (understandably) & based on the searching I've done I'm assuming that the phone is just DOA. However does anyone know a possible answer to my second question which is, if the phone is un-savable is there still any way I can access files like pictures by plugging the phone into my computer while the fastboot screen is up?

Oneplus One Won't turn on

Hello I am having trouble with my Oneplus One. It won't turn on. Here are the details:
After 4 years of using, my battery could not support my phone. If I was using my battery's power, the phone would constantly reboot. So I plugged it into a power bank 24/7 in order to use the phone. It worked fine. Then, one day it would constantly reboot after the "cyanogen mod ready" screen.
Now, if I try to turn it on without it plugged in, it shows the oneplus logo and "poewred by android" screen, and reboots every 3 seconds with a vibrate. If I turn it on while plugged in, it passes the oneplus logo screen, and shows the cyanogen mod ready screen for ~10 seconds before powering off to show the battery charge percentage screen (at 100%).
I'm not sure how to fix this, but a possible solution is that I may need to replace the battery. I want to know if replacing the battery will wipe the data? I am trying to recover my photos and get my account from the LINE app. So I must be able to use the phone after. Where can I buy a working battery to replace it?
If the battery is not the issue, is there a solution to this?
Thanks so much

Zenfone 5 Selfie/Lite (ZC600KL) stuck on ASUS logo

Hello! I could not find a section for my phone, so I am posting here.
My Zenfone 5 Selfie/Lite (ZC600KL) randomly "bricked". After being left alone charging for 20 minutes, when I came back it was turned off. Holding the power button resulted in the phone showing the "Powered by Android" logo, then the ASUS logo, and stop there.
I don't think it's a battery issue as it always lasted a long period of time; this is the first time anything like that happens, and might be the last. I also never tried meddling with my phone (rooting or the likes of it), so I'm pretty much clueless. I messed around with the phone, turning it on and off for a while, letting it run out of battery and charge it again, leaving it stuck on ASUS logo over night, to no avail.
Here are some things that I noticed that might help solve this problem:
1. After I connect the charger, the screen shows an empty charging battery along with the LED showing the red color (which means no battery). After 5 seconds, the screen turns on again by itself to show the true state of the battery, which is whatever % it is right now and the correct LED light (orange/green).
2. Turning on the phone makes the "low battery" buzz followed by a normal vibration. If it's charging, the "No battery" red LED shows.
3. I can turn on the fastboot mode by pressing Volume + and Power, but it only shows "CSC Fastboot mode!!! Long press power key to shutdown device". While on fastboot, my computer recognizes the phone is connected through USB, but I cannot access the phone's storage.
4. Pressing Volume - and Power does nothing besides restarting the phone.
My english isn't the best, so I apologize. If there's anything that I messed up and you can't understand, please do tell me.
P.S: Zenfone 5 Selfie is the same phone as Zenfone 5 Lite, but it is known by both names for some reason. Thanks for reading.

Exactly the same problem and phone I have here and Google research has been useless plus it appears this model phone has many firmware versions also
I have tried flashing firmware in fastboot mode but the ADB and fastboot tools won't work as it shows write protected as it appears bootloader is locked and am struggling with QPST also got so desperate to get phone working I even checked out some of those android repair software like DR fone then realised they want $70 USD and instantly removed the software haha
Hope we can get answers but seems like that maybe no one has solutions for this
