[Q] Desire wont start up. The screen just keeps flashing.

So i went out on a night out and my battery went flat whilst i was out. I come to start it after charging it up and it just keeps popping up with the start up screen for a split second and then going off. It keeps doing this until i unplug the charger or take the battery out. I managed to get into the reboot screen and tried starting it from there to no avail. The battery is only a couple of months old so that should be good.
I took it to a phone repair shop and they said the board was gone and that there was nothing that could be done with it. Is this the case?
I don't generally turn it off just keep charging when it gets below 20% battery life. I did however install solitaire since i last powered it down if this might have any influence on the situation.

Check if you can get into the bootloader. Hold volume down and power.

I have tried this but although it comes up with the bootloader screen it flashes off gain as with the boot up screen. It does not give you time to do anything in the bootloader.

Are you sure the battery isnt completely dead? Did you drop the phone or do anything that may have caused this, or did it just suddenly occur?

No i have charged and recharged it until the green light comes on. The chap at the shop tried another battery also and this had no effect on it.
I dont recall dropping it. It is in a substantial wallet holder so i would think that would take the brunt of the blow even if i had. But it worked fine all night until it powered down then it just started to play up.

Right while messing a bit further it seems to me that the on off button is constantly activating. If i just hold the return button it comes up with the reboot screen and allows me to choose the various options. If i hold the volume button the fastboot screen appears but disappears just as quickly. All of this happens with out me touching the on off button so it looks like it is constantly trying to start up. The button does not have any visible signs of damage. Is this a normal failure point for these phones?

If it charges completely while it's off, then the board should be fine. You can check the percentage in your recovery mode if you can get there.
If the board is fine, it either means that the button is stuck or you have some gunk short circuit in the button.
If it's gunk, you might get away with some rubbing alcohol, If it's in a spray can, even better. If it stuck, it should be opened and see what's keeping it pressed.
I hope this helps.

Screen Replacement issues

I recently had a buddy get a screen replace from a place in the mall. The phone display and everything works, but one problem after all of that. It will not stay on and keeps bootlooping ect.... I did a factory reset and still no luck another weird thing is, when it is plugged in the battery will go from 80% down to barely nothing then quickly charges back up. The phone somewhat seems to stay on when it is plugged in. The phone started having these problems when the screen was replaced. Im confused. please help! Thanks!

sure its simple

First thing first do a hard factory reset with the volume down and power button, not work then flash with lg flash tool the model numbers kdz all downloads and guides are posted. let it fully boot power down then fully charge, power up and down several times so the data files understand the new digitizer and resets all problems. Still dont work find screen replacement video via youtube once there whatch how to disassemble cause I am pretty sure it is one of the data cables or connections that is loose but you can never know with software and those are easier to do and less chance of permanent damage.
Or you can mail it to me and I fix her right up lol

Help! Blue screen, no download mode, can't factory reset.

Hello!
A few months back I rooted my Verizon LG G3 without any issue. Worked great, went smoothly.
Last night I was watching Netflix when the phone suddenly shut off without warning. I haven't recently installed anything out of the ordinary. When I tried to reboot, I got the green screen with a HW reset warning. Pressing Vol down to reboot gave me a blue screen. I'm able to reboot using Power + Vol down, but if I try any of the options [including factory reset] it suddenly goes to the blue screen.
I also tried getting into download mode without any luck - you guessed it: Blue screen. If I connect the phone to a PC, it doesn't recognize it. I've tried downloading and running the LG PC Suite, but it can't connect to the phone.
Any thoughts on what's going on and how I might be able to repair it? I've looked through various threads here and anything similar seems to revolve around flashing gone awry...and I'm not flashing anything (nor do I really have the know-how to do so).
Thanks, in advance, for any assistance.

Do you get the blue screen when attempting both recovery and download mode?

Blue screen no matter what I do - recovery, download or normal mode. As a matter of fact, now the phone won't attempt to boot at all.
Really strange.

I feel you. I started a thread about my issue but sadly no one helped...
Seems like you got a "bricked" phone though Qualcomm phones are theoretically unbrickable.
I was in a worse situation than you, I think my board fried haha, but i'll try my best to help you here
Do you have a custom recovery?
IS there anything else showing on the blue screen? (example: Factory Reset Status)
also does your led flashes?
If you can't boot, or flash through download mode (KDZ and TOT method) I think either your bootloader got messed up (for no apparent reasons apparently) or it's simply a physical defect.
Are you sure your PC doesn't detect your phone's USB after installing the appropriate drivers?
Or does it detect the a device as "QDLoader 9008"?

I appreciate your help - thank you. For what it's worth, no - there was never any text on my blue screen, and I couldn't ever get it to get into Download Mode. Plugging it in to a computer did nothing except give me a blue screen, and the computer never recognized it as a device.
I ended up getting a replacement G3, so [for now] my troubles are over. Thanks, again, for your help.
(I guess this thread can be closed now.)

Quick update: I just learned today that a co-worker who also has a G3 (T-Mobile) also got a blue screen last week. He was told that this was a "known issue" with this phone...but they wouldn't provide him with a replacement, which also seemed strange.

Glad you got it replaced!!
And a shame for your friend :/
In my case, it was practically hopeless, nothing seemed to work, eventually i had to have the motherboard replaced. It was clearly a damaged bootloader, yet, they repaired it under warranty! funny
I doubt you can damage a bootloader without root or stuff.

I wonder what would suddenly mess with the bootloader after months of no issues?

I'm having the same issue. Or rather I had the same issue but I was able to get it back to stock through all the various .tot methods and using download mode and everything. I had no issues so I rooted it again, installed the 35B firmware from xdabbeb, as well as his 46A so everything is still stock, and running the latest android update, but the phone is still rooted. In any case it has been working fine for almost a week. Today it shut itself off again and now only blue screen when I turn it on. It barely gets past the LG logo before it blue screens again. I can't enter download mode because while installing the device on the PC it blue screens and crashes in download mode.
So I'm not sure what the deal is. I have the extended insurance and warranty but if you pull the battery for a couple hours and put it back in it will boot past the LG screen and start the OS, but the boot loading screen shows "Android" instead of "Verizon" so they'll know it's a custom firmware and do nothing for me. If anyone has any ideas I'm open to them! I would love to revert back to stock but with it crashing in download mode I can't even do that.

try these things but g3 is crap phone
you can try these things: use stock charger and try to boot then, i think its a 2amp charger. if it boots then swapping out battery with good one will likely cure it. its hard to find good new oem batteries though. usually that only works if you see a blue screen with a number on it. if its just a flat blue screen and connected to stock charger wont improve anything then its likely corrupted bootloader (hard brick). i currently am trying to resurrect one that is acting the same, it will only randomly turn on to blue screen, sometimes after days left with battery in while turned off. all the tricks like taking battery out, connecting to charger or computer without battery or holding power button to drain capacitors with batt out dont seem to help really. i am trying to get it to turn on into download mode at which point i will flash stock kitkat but seems like it wont happen. seems like lollipop 5.0 has something to do with this issue. there is an outfit on ebay that fixes it for 29bucks in texas. you will find them on youtube. g3 is crap. g2 was excellent except for touch screen issues.

can you explain what outfit in you are talking about? i am facing the same problem,

Sorry "outfit on ebay" means seller on ebay. Don't remember what their name was. With the g3 it's like this: bootloop is usually fixable with a new battery. If it loads with charger connected, then definitely try new battery. If blue screen without a number, it's likely faulty motherboard. It may still boot occasionally, after leaving batt out or putting in freezer (yes freezer). If it does boot then do a backup immediately but phone is likely in need of new motherboard.

BSOD is not so BSOD as you might think. This is actually the default view of the screen controller. It just means.... well... basicly... you're ****ed....
Something in the hardware doesn't fire up as it should and it's usually the SoC.... or the so called processor. Heating and baking might help if the problem is with low temperature welding but again it might not. And even if it does... it will be totally temporary (most cases weeks) because of the rapid increase/decrease of the processor temperature and thus welding joints... I'm basically in the same situation right now with the same phone... he fought well as it is 2014 phone after all but in the end it died heroically.... ;(

Can't boot Verizon G3

Having major problems with my G3; started last night. I noticed that my phone was on the LG boot splash screen and was unresponsive. I reseated the battery and it seemed to be working fine after that. However a couple hours later it was completely dead. If I reseat the battery and turn it on now, The LG screen comes up for a couple seconds, then shuts off. Never get the Verizon screen. I tried to do a factory data reset on it, and get the menu but once I select Yes, the phone goes back to the LG screen for about 2 seconds then shuts off. I got it to go into TWRP once, but it shut off before I could do anything with it. It'll boot into download mode, and my system detects the COM port, but almost immediately the phone shuts down. The phone was running fine before this happened. Any thoughts? I'm really scratching my head over this one.
TLDR:
- phone rebooted last night, won't boot now. Keeps shutting off before I can get anywhere.

Sprint too
Same thing happened to my Sprint G3 on Saturday. Had over 90% battery and was texting a friend back and forth. I put it in my pocket and about 20min later when I took it out it was dead and wouldn't power back on. I took the battery out and put it back in hit the power button and the LG splash screen comes on, then phone dies and can't get a response from the power button. I can do that over and over, but it never gets past the splash screen. Tried to get into recovery, but when I do, buttons are unresponsive and then it just turns off.
Stock ROM, never rooted.

I don't think this is a battery issue. I have 2 batteries and the problem persists using either one. The first is the original battery that came with the phone and the second is an LG stock battery purchased through LG in April (only 3 months ago).

Update 7/12
I followed kp263's advice and ordered a new battery. Put it in the phone and plugged the charger in for a bit and..... same problem. Won't boot past the splash screen. Just turns off.
This is more than just a battery issue. Hopefully I can return the new battery I purchased.

Nexus 5X randomly dies and then I can turn it on again only when its battery hits 0%

I have a N5X, unrooted, bootloader locked, 7.1.2 stock. It happened twice in the last week, the phone used to work perfectly before that. I just pick it up as usual but it doesn't turn on anymore, I tried multiple times to boot it normally or in bootloader mode but nothing happened; then the next morning I plug it into the wall the led flashes red and it reboots normally. I thought it could only happen once but it happened again yesterday night and as usual this morning it booted up. Does anybody know what the problem may be caused by? What can I do? The phone still has warranty and if no solution is found I'll send it back to Google. Sorry for my english.

I have had the exact same problem, mine only occurs when the phone is ran down to 0% and powered off. I never let that happen but I have a 3 year old son who repeatedly does it, and every time i hold my breath, praying it will come back on. Well i am holding my breath and praying once again this morning,hoping it will power back on. Do you think it could be some kind of "protected mode"to keep the battery or something else from overheating or whatever?

If you need the phone and are confident, try unlocking the bootloader, reflashing stock factory image and relocking the bootloader again. You will lose all the data, though.
If you can live without a phone for a while, just send it to Google/LG. Nothing else one can do imho.

When my phone was in the last steps of dying (eventual bootloop), I could disconnect the battery and it'd get farther through the boot cycle, or even once booted. Basically, after it wouldn't react to any buttons or combos, I would disconnected and reconnected the battery. Then I could give things another shot. So I'd start it, it'd make it to the colored circles, or I could boot to the recovery menu, and try some things, but at some point it would go black. Then it would not react to anything unless I disconnected the battery. Then it would react to the buttons again and eventually one of the steps would make it go black. And then take a disconnect to get another try.
It sounds like your phone may be close to dying.
By the way, I only opened it up since I was past the warranty expiration date, and LG extending the warranty to about 18 months wasn't a known thing at the time. It is actually easy to get everything apart, but hard not to make dings in the plastic cover even using plastic tools.
I would say, back up everything you can from it and expect it is going to get worse. Redoing the OS didn't save mine.
