Some serius help needed. Bootloop, stuck, bootloader not working etc..

Hi. To start with I bought a phone from a friend which I knew was faulty but decided to take my chances and try to fix it. He claims he did nothing to the phone but don't know for sure. Phone is in constant bootloop, Goes until splash screen and reboots. Worst yet to come - even bootloader menu restarts on constant basis when i try to get into it. Meaning it goes into bootloader but restarts in few seconds before i can get to factory reset. Computer is not picking up this device but i also don't have any drivers installed but don't even know how to install them with a phone in this state. Is there anything i can do about it? Been with Samsung for the past few years and here is everything completely different so don't know much about adb but am a quick learner and can follow any steps! I can provide picture of bootloader if it would be any helpful.

Send a picture of the bootloader while I find the drivers you need

Seems like battery is completely dead as it only reboots when there is power supply connected, but then it won't turn off (any charging light don't come on, not sure if it should though). Just now i've seen a vodafone logo for a very short second when I connected to pc from charger. But phone rebooted again just after.

edit. downloaded drivers (4.8) but that didn't change anything and windows still doesn't pick up device.
After connecting my one to computer for past 3 hours its started more frequently boot and showing Vodafone menu but still restarts shortly after. Vodafone logo shows on and lights on soft buttons starts flashing like 3 times and than it keeps rebooting. Does it mean anything?

That almost sounds like your POWER button is stuck!! Are you able to completely power off, and it stays off.

I think i know what it is. Power button stuck and keeps restarting device. Although i can feel pressing it, this is what it looks like.

Didn't see your comment but this is exactly how it looks to me. I can't switch off phone and in bootloader it acts like i was pressing power button. Although it operates normally meaning that it can be pressed down. Arranged warranty repair with HTC and they are collecting phone tomorrow.

Good luck mate, but definitely sounds like the power button is stuck

It's been fixed under warranty by HTC. They replaced motherboard on mine HTC. So all good

[Q] [HELP] Something is SERIOUSLY wrong with my Moto G(boot loop)

So. My Moto G is completely un modded, not rooted, and is exactly stock how I bought it and haven't changed any of the software. My Moto G has been getting slower in the past couple of months with everything going slower than usual. I bought my phone in February 2014.
Yesterday while I was at school, in my pocket I had my phone. I felt random vibrations in timed cycles. So I pulled out my phone and had a lol at it randomly rebooted but came back to the home screen. As I started to use it just to send a couple of messages it rebooted again but this time after the reboot animations they just went on and on, what I've found out to be called a boot loop.
So I went home did some research and figured I would have to factory reset. I couldn't get into the phone therefore I had to do it externally. I got the the menu thing ( I think it's called fast boot menu ) and I wanted to select newer bootup or power up just to see if that would possibly stop the boot loop. I selected it and got into my phone, into setting and factory erased my phone.
Well I factory erased my phone and re installed the apps I on,y essentially use or NEED such a social media, within this time there was no unusual activity. Shortly after my phone randomly rebooted ( after downloading the apps ) and turned off, and then went in to the former boot loop! I was furious!
Well here I am, left it overnight for charge and it's been looping for 10 hours. I tried going back into the fast boot menu, the first time I got into it this morning I selected recovery in hope to reset it, however the screen said no command with the android and the exclamation point. The second time I got into the menu I tried 'Factory' and it just rebooted and back into the cycle.
At one point I did get into my phone however shortly after that guess what happened, it turned off and rebooted. And back into the vicious cycle.
I am led to believe it's the power button that's causing the problem ( correct me if I am wrong ) as when I did manage to get I to the phone I did try pressing the power button to investigate this and on some occasions in did lock the phone but in several others it displayed the power off popup and then turned off shortly after indicating that I was holding the button down which I definitely wasn't doing.
So where would I go from this? Do I call Motorola, try flashing a stock ROM ( it's completely stock ATM , I don't know how to do this so if I have to do this can you please explain briefly ) or try going back into the fast boot and go into recovery and try and get rid of no command ( if I can, and how ? ).
Please any help would be very appreciated!
Thanks in advance.
PS you don't think it's the back cover that's doing it because it took that off last night '

Since your phone is completely stock, don't start tempering with it now. Just return the phone. But you have to act quick, warranty is about to expire.

Hi, I had a look online and came across a forum post saying it was a jammed or sticky power button and the poster stated to hit the power button side of the phone on a desk a couple times and it will go back to normal. I'm glad to say it did work after I hit it a couple times, as fast as ever now due to the reset!
I was wondering if I call Motorola would they give me a free new moto g out of it, as I see it as an opportunity to do so, or will they just prompt me to send it so they can repair it under warranty? Is it worth calling ?

[Q] Help! Trying to troubleshoot and hopefully solve problems with HTC One.

Hey guys, could anyone shed some light on what's wrong with my phone?
The initial problem was that it would display a notice that the phone was going to restart, the phone would turn off but not reboot.
When trying to turn the phone on immediately afterwards, it wouldn't turn on. The first thing I tried was seeing if that battery was dead but even when I plugged it in, it still wouldn't turn on nor was the charging light on.
After leaving it for a while, I tried a hard reset but the phone would turn off after 2 seconds in the boot menu. After a few hours and a lot of expended patience, I got the hard reset done and it worked flawlessly for around 30 minutes then turned off again.
Right now, when I turn it on, it shows the HTC screen, the backlight for the icons at the bottom flashes around 10 times and it turns off.
Any idea what's wrong?

Kinda sounds like your power button may be sticking in. Is the device bootloader unlocked and rooted? Or still stock?

The phone has been unlocked to be used with SIMs other than from AT&T but it hasn't been bootloader unlocked or rooted.

Ok I would recommend you check warranty to see if it is still covered. To try a software solution will mean unlocking the bootloader which will void warranty. And may not fix the problem. As I say it seems like the power button is stuck in.
When the capacitive buttons flash like that it is because of a forced reboot by holding in the power button.

Major problem. Phone Stuck at start up logo

This morning during a call my phone shuts off for no reason. It is not rooted no physical or water damage. I tried to power it on it will vibrate than attempt to start get stuck at boot screen than eventually turn black. I tried booting into recovery to hard reset I will get to the menu do all the prompts and get the lg logo and back to black screen. I don't know what is going on. Is this a common issue? Admins if this is in the wrong section feel free to move it.

Not sure what caused the issue but if wiping from recovery doesn't work I would look into restoring phone with kdz file. Sucks to do that seeing as all data will be gone but hopefully you have a backup. If restore doesn't work you need to call T-Mobile for replacement
Sent from my Porn Infested G4

The replacement has been processed. Unfortunately trying to factory ? reset doesn't work because the phone ? wouldn't stay on long enough for that to happen. Love to know what actually caused this issue. Kinda kicking myself for not doing a weekly backup.

I actually got the same problem on mine but mine is rooted and was working fine but then randomly my phone is doing bootloop. I don't have terp installed and I'm I only able to boot up to software upgrade mode. Ive tried the step for format everything with holding the volume up n on button but after I did the reset stuff still does boot loops. Also another problem is that whenever I plug in phone to computer it doesn't show up, so I have no option to add roms or anything like tht to internal or sd card. Is there anyways too flash anything of the software mode, if so can you plz let me know thank you.

H811 won't boot after multiple battery pulls... HELP!

So I can't boot my phone. Previously stable h811, unlocked bootloader running latest 20i Extreme 3.3 MM with G4 Tweaksbox. I have a Qi/NFC sticker on the back, but which has worked flawlessly and was not in use when the phone died. Here's what happened and what I have attempted.
Problem began when phone simply went black. The only thing running was Maps, which had a route displayed but was not in navigation mode. The screen went dark like normal, and when I went to wake the phone, nothing happened. I was in the car and tried plugging in the car charger and did not get a charge light. Pulled the battery and was unable to get a response. The phone and battery were quite warm.
When I got home, I tried a different battery, and the screen turned on to the LG initial boot screen, but nothing else happened.
After many battery pulls and attempts to boot into recovery, I tried it with the phone plugged into the computer. Finally, it showed the charging screen and light, and after several more attempts- pulling the battery and inserting it, then powering on, it appeared to be booting, (boot animation started, but then looped and froze on the initial boot screen (with bootloader state: bootloader unlocked in the upper corner). After another round of attempt/battery pull, it booted all the way up, but at that point I had my sim pulled. Pulled the battery and tried to restart and it froze on the initial boot screen again. Haven't been able to get into recovery at all, can't get into download, can't boot past the initial LG screen. Sometimes it loops, sometimes it just hangs. Nothing I do pressing combos of buttons, plugged into computer or unplugged, seems to change anything. The very farthest I've gotten is the breathe blue light before the boot animation, but then it looped. Now it's boot looping plugged into the computer.
Any ideas? I'm at a total loss.

Black screen of death here too
Yesterday, I was using Chrome, site loading, screen just went black. I had about 1/2 battery at the time. I figured maybe the battery was just reporting wrong. When I got home, swapped batteries, same issue. I've been able to get into recovery and attempt a factory reset a couple of times (after many frustrating attempts.) The phone seems to only be able to be powered on for about 30 seconds before it goes black again. I'm going to attempt to fix with download mode now. If anyone else has solved a similar issue, any tips would be appreciated.

Hardware appears to be at fault!
Check this out, people!

Spread the word. Sounds like this is our problem. Apparently affecting mostly models with serial numbers starting 505xxxxx... which is what mine is. Called LG and they issued an RA# and shipping label to send it to them for service. I'm a little concerned since I didn't buy mine through a carrier, but this seems more like something of a soft recall than strictly a warranty issue, so I'm hoping they fix it no questions asked. I'll keep you guys posted on the progress.

Same thing happened to me today. My phone randomly shut off and it won't boot. Its stuck at the Android logo. I wasn't messing around with it. Just normal use (Snapchat, youtube). I tried booting into recovery but it just goes back to the android screen LG logo and keeps looping. I at least want to wipe the phone before I send it (personal info).

Same here. Mine has serial number starting 505, was purchased back at end of 5/2015 with not problems until this. I filled out the warranty repair form on LGs website and they sent me an RMA with label to get it fixed. I sent it in, they sent it back, and the only thing I see is on one sheet they printed out and included in the package said 'replaced board'. However, when I started up the phone it looked like new initialization with xx of yy apps initializing and then it began bootlooping with the LG splash screen. So frustrating!
So, this time I contacted t-mobile via their online chat, and did a warranty exchange through them. They will send me a replacement LG G4 next day ups air and I will send them the defective one for them to claim warranty themselves. We'll see where this goes. I might just take the replacement unit and do a tmobile jump exchange to another device. I wanted to wait for the new line of HTC nexus phones that are rumored for this year (and was loving the LG 4 until it died), but I might need to just jump twice this year and go for something like the new Samsung S7 of new LG G5 now and then again switch to HTC nexus once that comes out.

Sent mine to LG, and they fixed under warranty with no questions asked. Got it back within a week. All good now.
