This is my story that happened with my LG G2
I recently purchased a LG G2 F320L, a refurbished one, from aliexpress(I think this was the biggest mistake of all)
I got the phone, I started using it, used it for 20 minutes and just installed antutu benchmark and ran the app and started the benchmark.
Firstly, I'd like to mention that the phone just got warm, just like other phones, during the test. While the multicore performance test was going on, the phone turned off, all of a sudden (Battery was as low as 9% when I started antutu benchmark). I thought that, it was because the battery was too low to run a benchmark app and turned on the phone back and waited, it just showed me the LG logo for 5 seconds, powered off, ended up with a bootloop. :crying:
I thought that the OS or the bootloader got corrupted and stuck and also thought that I could easily fix it by flashing boot.img or the original .kdz using LG flashtool.
I connected the phone to the PC, it was charging from 9% (That means, low battery isn't the reason for this problem). I waited until it charged till 25% and tried turning the phone on again, but, the same bootloop happened again. I downloaded the .kdz file for my exact model and prepared to flash it using LG flash tool. Unfortunately, the phone came out of download mode (Whilst the flashing was going on) and started with the bootloop again. I really got scared cause the flashing was interrupted indefinitely. I didn't know what to do and I just googled how to enter factory reset mode and I finally entered factory reset mode and chose to reset the phone completely. But, it has happened for a while and continued with the same kind of beat-up (But I was able to enter the factory reset mode later on, though) I was pretty much scared at this time and I gave the phone to one of my friends. I showed him the factory reset mode that was still working, but not useful, and I tried resetting 3 to 4 times but couldn't come out of the bootloop. But, suddenly I couldn't enter factory reset mode and the bootloop became pretty much faster that before (Just showed me the LG logo for 3 seconds and rebooted with the same bootloop). Now, no factory reset mode, download mode, and no charging either.
I got to know that it was a really serious hard brick that has ever happened to one's phone!
I handed over the phone to another one of my friends and he dismantled the phone and tried something, then connected to the computer and the computer detected the phone and QHUSB mode was saying 'Searching Windows update' with a loading symbol. He just stopped it there and told me to take it to a good service center (An expert, of course), and he also told me that I was supposed to ask him, to make the QHUSB mode work.
But, after he gave me the phone back, the bootloop was still happening, just like before, but, instead of LG logo, it was showing some bluish white lines on the 2/4 on the screen.
I haven't got time to go to a service center till date, as they might cost me more than I invested on my phone.
This is really serious problem and I need to enter the QHUSB mode and I need to flash the stock firmware cleanly. Please anyone give some time to read this thread and help me out in this situation. AGAIN, I have used the phone for like, just 20 minutes when it was in a working condition.
So, I request any experts to help me out, suggest me the solutions.
Sorry for my bad English, though.
Thanks in advance.

Hi:
I have a HTC sensation 4G. I really like the phone. However, about 3-4 months ago, my phone suddenly switched off. When I restarted my phone, it got stuck on the HTC logo and wouldn't go further and switch off. It would start again, show the white screen with the HTC logo and switch on again. It wouldn't go any further and kept doing so in a loop. I thought there could be 2 possible reasons for the same: 1.) software issue or 2.) Hardware issue. I was pretty sure it was not a software issue as I had not made any changes in the software. I took it to a HTC repair center. The repair charges they were asking were freakingly high (300$!!). I didn't get it repaired from them. However, they gave me the exact reason of the problem. They said that it was a hardware issue and often happens with the phones when battery of the phone is removed while the phone is running. If this is done multiple times, such an issue can arise. I had done it multiple times before the phone had stopped working. I then got the phone repaired from another shop paying a third of the price. He didn't give any guarantee if the phone works. But the phone started working after the repair.
Very recently though, I was using my camera and as soon as the flash came on, the flash light got stuck. The phone was, however, working. But I couldn't get the flash to switch off. So I thought of restarting my phone. The phone switched off and when it turned on, it had the same problem. It is stuck in a loop on the HTC logo screen. I think this could be a software problem. What can i do to repair it?
Another thing I want to mention is that I am unable to go even in the recovery. When I try to go in to the recovery, it switches off and shows the HTC screen again. On one occasion when I tried to go into recovery from the boot screen, it showed a message that the battery voltage is low, please change the battery immediately. So i thought it is a battery problem and I looked up on the internet to find a solution. Somewhere I read that sometimes the gold plated contact points on the battery get scratched and corrosion happens. One solution was to clean the corrosion and try again. I did but didn't work. Also, when I try to charge the phone (because the battery voltage is low), even if the phone is switched off, its starts up again automatically without pressing the power button. Then it keeps going in the loop.
I don't know what the problem exactly is. Do i need to change the battery? I am running official HTC ICS ROM. Please help me with a solution.
It will be of great help. Thank you!!

Hello guys.
About an hour ago, I tried to access my WiFi configs, and realized it would take me back to the start screen. So I rebooted my phone. The thing is, it is now stuck in the big red Motorola/Intel logo, and keeps looping.
If I try to turn it off by using the Power button, it doesn't work. If I try to reset using Power + Vol Down, it just restarts the loop. I can't get into recovery mode, because it won't turn off.
I really don't know what to do. My phone is still trying to boot for the past hour, and I really need it, asap.
It is running Android 4.1.2. No root. As stock as it gets.
Any advice, guys? Please

I have the exact same problem.
My phone (non rooted, stock Android) has been freezing quite a lot for the past 1 or 2 weeks. Sometimes rebooting on its own, sometimes I had to force it. This afternoon it froze again and I had to force reboot, where it started freezing at the Motorola logo. I cant go any further since rebooting just makes it loop that way.
I waited for the battery to deplete so my phone eventually turned off, charged it back at around 60% and tried to go into recovery mode with power+volume up+volume down. Same results. I don't think I could have failed the recovery mode procedure because I had practiced and knew I would only get 1 chance of succeeding.
Anyone has experience with this ?
I will see if Motorola or my retailer will repair/replace it for free under warranty terms, otherwise I will try opening it up for some cleaning and maybe further attempts with control over the battery.

Well, Motorola did repair my phone for free, but I live in Brazil. It took them 1 day to repair. They say that part of the circuit board was damaged, but I don't know what could be the cause. Maybe overheat? I don't know about your phone, but mine would get up to 50ºC while using Skype.
Dear XDA mates,
I am facing this different kind of issue currently. None of the process on my phone are working. Here is what has happened and what is happening:
What happened:
1. I dropped my phone in water. It soaked in water literally.
2. I dried it off but saw that phone was starting and shutting down automatically. I kept it the way it is so that it can dry off further.
3. Couple of hours after I started the device and it was all working but I wanted to make sure it is working fine so switched it off and kept it to dry off till next morning.
4. Next morning phone was not switching on.
5. I put in on charge and after a while try to switch it on. The phone started but was giving me zero battery alert and switching off. I thought it is a usual battery going dead issue and left the phone the way it is.
6. After one day I kept it on charge again but nothing happened so I finally decided to take the device to service center.
7. Stupid service center technician told me, phone is dead completely and motherboard has to be changed. I decided to not do anything with the phone and brought it back home.
8. I kept it on charge and guess what, phone was full charged next morning and it started again.
What is happening:
1. The phone started but now as soon as I unlock the phone, I start seeing errors. (Unfortunately, Google Play Newsstand has stopped, Unfortunately, com.google.process.gapps has stopped, Unfortunately, Weather has stopped etc etc, the error never ends).
2. Now it thought of doing a factory reset, went to Fastboot mode, selected the Factory option, phone goes to Moto logo and I see the same old lockscreen. Phone is not resetting.
3. I thought of flashing the phone with stock firmware, went on fastboot mode again, tried to go on Recovery option. Phone returns to fastboot mode with error (in yellow font) "Boot up failed".
Now I am stuck, I see some serious problem has happened for sure.
I need some super expert help and need to understand what might have happened to my phone.
Sad for you, mine opinion is it might related to hardware issues. Hope some pros may come up and help you here.

Follow this guide and everything will be good
Tried flashing but nothing happens
I have tried flashing it too. When it fastboot mode, I see that all the processes are running as intended and once the flash is complete and my phone starts with Moto G, guess what - I see the same old wallpaper and lock screen. It means phone is not flashed .

I suppose that either means you flashed incorrectly, the phone is still wet inside or the phone is damaged.
Try drying it on a warm, dry place for another day or two.
Good luck!
Will trying flashing after 2 weeks of phone phones processes has stopped
I will flash it today again.
Which is the best process to flash the Moto G phone. I have followed couple of methods and they haven't worked for me.
It could also because of the battery issue. I read it on another forum that Factory cable might help.
Can you or anyone else point me to Factoty cable. Searched all over ebay and all I could see is Factory cable for Moto Razr.
Let me know guys.
Thanks.

I'm similar situation. Only my daughter's Moto G (android 4.4.4) was not physically damaged.
After sreen unlocking the phone shows errors "Unfortanately [everything] has stopped working".
I flashed stock recovery many times but it does't help.
And one more thing: if the phone is connected to the PC it is possible to run fastboot commands, but the phone filesystem is not accesible.
Is this a hardware problem?
P.s. Sorry for my english

Flash the stock rom via fastboot dat could fix the problem:good:
I have only had it for about 16 months now. It is a MetroPCS GS7 so it's a T-Mobile variant if that matters. Never been rooted or modified in a similar way. The same thing happened with my previous phone, a GS4 which never got fixed. I was just using a video downloader app when it suddenly restarted. It only shows the first screen for about 5 seconds then restarts. I have some experience using ODIN and flashing ROMs but I don't know what I should try with a GS7.
After a few tries to get it into recovery, this is what happened. The blue recovery message in the top left showed up but I didn't let go of the buttons this time. Then this rotating white circle showed up and said something like "applying system update". After about 20 seconds then I got a screen with the dead android and it said "no command" below it. Then I don't know what happened but then suddenly the recovery menu showed up. So I picked to just power off so it is just turned off now and no longer in a boot loop. I don't know what to do from here. I won't turn it back on until I get advice on what to do next.
If you just want to fix it without worrying about losing data, see if you can get it onto download mode and full a full stock flash with all 4 firmware files in Odin.
If anything is corrupt, Odin should give you an error message which might be enough of a clue as to where to look next.
OK so I flashed it once and it didn't work, it was still stuck. After that I just gave up on keeping anything and wiped all data. I flashed it a second time and it still got stuck, but after about 10 restarts it finally worked. However it is now on the T-Mobile firmware instead of the Metro PCS one and also I am having weird problems now. I would like to go back to the Metro PCS however I cannot find any firmware for a G930T other than T-Mobile. The problems I have experienced so far is the auto brightness does not work anymore, I have to manually set brightness even when it is switched on, the screen turns on for a few seconds when it's done charging now, and also I restarted my phone to fix an app and then it got stuck in a loop again. It took 10 restarts then worked again, but that is still a problem. I don't even know if I should still be wasting my time trying to fix this. I really don't want to buy a new phone right now but I also feel hopeless in fixing this one.
Hi. My close friend has this issue. I'm posting this because she can't figure it out by herself. A month ago, her phone downloaded an update and she installed it. Since then, the phone has restarted by itself without any reason, just random restarts and the frequency of restarts was more frequent with each day. Fast forward to this day and the phone is constantly turning up and shows the POCO logo and restarts by itself. This loop is not ending until the battery is completely dead. When trying to access fastboot or recovery mode, she can get there but only for few seconds (until the device restarts again) which is not enough time to make any changes / factory reset. She did not accessed developer tools in system, so the bootloader is still locked. Holding down power button does nothing. ONE SINGLE UPDATE screwed up whole phone. Can't do ****. There's no SD card or SIM card in the slot. Is there any "hack" to stop the phone from restarting itself? Note when the battery is completely empty and she plugs the charger, the whole nightmare starts again. I'm lost. Did you guys have any ideas what to do? Or is the repair centre only solution? (She cracked glass of the display, i'm not sure if that voids warranty. [it's not glass COVER, it's the glass which is part of the display])
Is this device unlocked? If not, then RMA.
If it is, my best guess is to get the device into recovery (or fastboot?) and immediately connect to PC.
If it holds, leave it there as it will charge, although at much slower rate.
When charged, use TWRP to try to reboot to system.
If it doesn't work, then factory reset.
Sadly, i can not get to recovery because in about 2 seconds the device will reboot. There's literally no time to make any changes - factory reset. Also the device is not unlocked. I hope RMA accept the phone even though it has cracked screen . Thanks for response anyway
Then RMA it is. If you're in EU they'll have to take it, even with the cracked screen.
But does the reboot happen even when connected to PC? Two seconds is enough to plug it in if you're fast...
Yeah, we tried every possible idea we can think of. Pressing the toggle button from different angles with different intensity to make sure it isn't stuck inside, covering up the proximity sensor (yeah makes no sense but even that we tried, lol). Tried with connected to PC as with classical charging brick. No change. Back in those days where smartphones doesn't have unibody construction and you were able to take down the back cover and remove battery it was way simple. Nowadays it's not possible to stop the phone from booting itself until battery is completely empty. My friend says the problem started about month ago, when the phone annouced that there is an update available so she downloaded it and installed it. Before that, there was no problem with the phone whatsoever. Maybe it's caused by some kind of virus but IDK which apps she was using. She didn't have rooted phone not unlocked bootloader in developer tools. Also i googled that it may be caused by "Airtel Thanks" app which she didn't have installed aswell. I will keep this thread updated as what happend to the phone cause i'm also interested what went wrong and to help future users who will struggle with this problem a solution. Thank you.
CaptainFedora, did you solve the problem? I have the same issue...
Yeah, actually. Sorry for not posting the answer although it was definitely her fault. It was the power button being pressed down (which made continuous bootloop). But the button was somehow pressed deep into the phone's body. So complete dissasembly was needed.
Btw. my friend lives in other country so we discussed this problem over internet. If i could have the phone physically with me i would definitely know what was the problem.
Hi.
Yesterday I had the same problem, the device kept restarting every 10 seconds, it didn't even come to any screen besides the first one with the POCO logo in yellow.
Things I tried that did NOT work:
restart
hard restart
fastboot (it did enter the fastboot mode, but only showing the picture of the 2 robots and after 10 seconds restarting again to the POCO logo image)
plug it to power
plug it to computer
After 3 hours of continuous restarting and trying anything I could find in the internet and I could imagine of (except extracting the battery because it seemed complicated and difficult to revert), I tried randomly something that miraculously worked...don't ask me why.
pressing the power button shortly and quickly around 30 times (it might have worked after 10 or 20, but I just kept doing it a little longer
Afterwards it just started as if nothing had happened...doesn't make any sense, but I just wanted to tell you in case you are in a similar situation and desperate to not lose all the images and videos as I was yesterday.
