[Q] Boot loop: Can't enter Firmware Upgrade mode - G3 Q&A, Help & Troubleshooting

I'm posting a question as I've spent days searching with no luck.
I have an LG G3 that while in normal use got very hot and turned off. Now it gets stuck at the LG logo and doesn't boot. I tried a normal factory reset but this just goes back to the LG logo and nothing happens.
So I'm trying to get into the download mode "Firmware Upgrade" screen to flash the stock rom. I hold down volume Up, and plug in the USB and it gets to the little "Download Mode" icon but does not continue to "Firmware Upgrade" and the computer (I've tried 3 different systems) wont recognize the phone.
Interestingly at some point while being in download mode it switched to fastboot, I have no idea how this happened but I was able to run commands on the phone using fastboot.exe, however I have not been able to get back to fastboot since.
Also I'd really like to be able to recover the data on the phone.
Any help would be appreciated.

Thanks I tried the drivers you've provided but still no luck. The computer won't detect the phone at all, it doesn't attempt to install drivers nor does the phone show up as a generic device.

I hope not, this phone was purchased in Media Markt in Germany and it's not covered by warranty here. LG Australia said it would cost up to $260 for them to fix it and the phone could possibly be downgraded if the mainboard needs to be replaced. I don't know if it would be possible to claim the German warranty.

[Q] G2 stuck at boot logo no download mode no recovery device manager wont recognize

ok i see lots of threads about G2 stuck at LG logo with no download mode etc but none specific to my situation so figured id start my own.
my phone is stuck at the lg logo when i try to boot, when i try to go to download mode it shows the blue dots but windows, flash tool, nothing will recognize the phone as being plugged in, and not even the little sound windows makes when a usb device is plugged in, its been a little while so i cant remember EXACTLY what the last thing i did that bricked it was, something i did on command line with aboot something, i can try to dig it up if absolutely necessary but it would take some digging...when i try to boot into recovery it freezes at the "loading recovery screen, when i try to go to download mode it sticks at the blue dots and wont respond to anything, when i try to do a factory hard data reset it says "hard reset processing" or something similar then freezes there, ive tried reinstalling the drivers, using different pcs, read through countless threads, but have had no luck, any ideas what i can do to unbrick my brand new g2?? thanks in advance

This is what i would do....looks like your cable works, looks like you know how to get into Download and Recovery Mode. You have to get it to be detected, if it boots into Download mode it should work. Try re-installing the drivers.

with the phone off (completely), hold volume button (up i believe), and plug usb into computer. This should bring up download mode. If volume up doesnt work, try volume down. If you get just to the dots, then your download mode is broken.
was just about to start a new thread but didn't want to get into trouble..anyway I am in need of some assistance please.my ls980 has been bricked for some time now been searching all over the internet for a solution to be stuck back at square one.found this video on youtube which is pretty much exactly what my phone is doing.I have used lg flash tool to revert to stock and still nothing I lost root doing that but last night,I managed to regain root access I have no idea how but it happened when i clicked ioroot batch file i went into download mode and it stated bottom left ROOTED in red so i managed that but that is it still doing what is being shown in the video its on youtube

Flash stock zip kernel from artmod thread.
the problem is. I can't upload any files to mobile phone. if i connect to pc, it turns on, goes to recovery, so I click on mount storage, and other mount option, nothing happens. My computer detects phone as F180L with a exclamation mark.
If i go to download mode, and then try to flash any KDZ file from all the f180 KDzs. It gives me errors.
LG Support Tool on entering serial number and model name says "check out serial number and model"
ADB never detects my phone. So I can't upload anything.
No option to upload files via SD Card.
ok, so I have no clue what happened :crying: phone was in download mode. I did nothing, but only installed LG Support Tool USB driver, while the mobile connected.
Then I installed Microsoft .net framework 4.0. And my phone is now qhs_usbdload. it's officially bricked now. I have no clue what happened. This is all that happened before I restarted and selected "reboot to bootloader" and its dead. So there's nothing left to do but throw it out
WTF OKAY! I have no clue!
But, after seeing that qhs usbdload. (i have seen that before with other phones). I complete lost any hope.
So I for feeling contended, downloaded qpst, and emmc software download, and selected MPRG8064.hex and msimage.bin.
Then like I expected it threw an error "image download failed, cookie if present not received"
so I lost hope disconnected my phone and put it there. After a few minutes thought I should try one last time.
so I connect it my pc and VIOLA it turns ON!?
now I have that same rebooting to recovery problem. I have no explanation for whatever has happened to phone in past 3 hours. I have been with phones for years. This is the weirdest thing to happen ever :angel:
Now someone, please help me?
1. Why is this in Development section?
2. You can't mount internal SD as USB storage. Use adb push or adb sideload instead, that will help you to get the files onto your phone.

Some user got that problem before. I am not sure about how they solve it but I guess that they flash their original KDZ back. If your phone can enter download mode, you should try LG Flash tool 2014 and flash your original kdz to restore incorrect system image.
About adb cannot find your phone, try to remove adb driver from device manager and reinstall LG usb driver.

My phone is acting weird. Sometime it would start. Sometime the red light would blink. Sometimes the red light wouldn't blink at all. Then sometimes, it starts. And then it doesn't.
I have no clue what is going on with it.
But it went to download mode many times again, it would go to fastboot, bootloader, recovery etc. Then sometimes it will not respond to any buttons at all! I know its battery is down, but idk if it's charging or not?
I don't know how to know whether the phone is charging or not. I left it charging for 30 minute, and it didn't even buzz. :crying:

One thing you can do (I've done it in the past a couple of times) is to crack your phone open, disconnect the battery, and charge it with an external charger. That would at least give you a full battery to start with...
Regarding the charging problems, I had that once. I was able to startup the phone by simply using a 2A charger instead of the LG's 1.2A.
When I had this issue it was charging while in recovery. Please look at this post and flash your kdz.

thanks. but after charging it. I couldn't turn the screen off because it goes in recovery. I turned off the phone after good 30 minute charging. Then went to sleep. And in the morning I connected it to pc. by holding volume buttons for download mode. It didn't go to download mode. Only it's red light is blinking. and no display.

Hi, regarding that. I was able to sideload exitrecovery.zip file. It goes to 100% then nothing happens. Nothing happened on phone screen as well.
And can you send me link to that stock zip kitkat? i have a miui.zip and few other roms that I have not tried. thanks
Edit: also what should I do about adb, am i doing correct?
Becuase in adb devices, my device is displayed with deviceID sideload
And i have only pasted adb folder, with a dll and a zip file, there is nothing else, do I need to install SDK?
I tried lg flash tool 2014 again, and it flashed, I swear yesterday I tried to flash it, and after clicking on it, it never showed me country and language selection menu, so it would sit there and do nothing. now I don't know how but it did it :laugh:
thank you so much you'all

I think I might've hard bricked my phone!

I tried uninstalling xposed from my phone by recovery and it caused my phone to go into a bootloop, I entered recovery and tried to do a factory reset to see if that'll fix the problem but now my phone gets stuck on the "SONY" screen and I can't get past that. Even connecting a USB to my computer doesn't detect it, Is there anyway to fix this? :crying: :crying: :crying:
Get flashtool if you don't already have it, then download the firmware for your exact device model, then click the Lightning button and then follow its steps
I've tried that already but my PC doesn't detect the phone, I can't even get it into a fast boot mode. It only charges my phone when I connect a USB. Edit: It's fixed now, I was using the wrong USB. Thank you!

Please help me buddies!

Hello there pals, I have a problem, I have an Lg H815P (Mexico Version), and i was using it normally for about 15 days, then suddenly the home screen freezed, and then the phone restarted, i thougt it was just a lagging issue, but then, when the phone booted up again, after like 5 secs it freezed up again and restart, a infinte loop, then i said, this Rom must be corrupted (Stock TELCEL Rom v20b Android MM), and decided to do a hardware keys factory reset, then the phone restarted but when it was android upgrading apps, it kept restarting, at last it booted up but the problem persist. So im kinda worried, how a problem cant be fixed at a full hard reset? When im trying to flash a KDZ file From lg flash tool, the program fails because cant find phone, a kinda weird thing because the adb detects it sometimes, others not, i booted the phone in safe mode and the problem persist anyway, what can I do? I already have the drivers, the lg up, and the lg bridge apps, they all said that im running the last software for my mobile device, i´ve tried another battery as well, so im kinda lost, another thing, after the hard reset, the phone was able to stay on like 15 mins, sometimes 5, sometimes just secs, dunno what is happening but i really need some ideas, can you help me to work this out?
Greetings pals!

I have had this problem occur because of the launcher. Try cleaning the cache and data and see whether an updated version is available. You could also try a 3rd party one and see if that helps or simply re-install the LG launcher.
If no luck, you could try flashing another kdz with LGUP-NEW: https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
There are a couple of TCL kdz's listed on this site: https://lg-firmwares.com/lg-h815p-firmwares/
Scroll sown to LG H815P Firmware List.
Back up everything first.

Make sure you are using the correct LG Mobile Driver on your PC: LGMobileDriver_WHQL_Ver_4.2.0
If you are using the drivers your PC installs, you will have issues. Check in Device Manager on your PC.
Use LGUP-NEW to install a kdz.

I found the correct drivers and installed a DLL for lg up, so the program now detects my phone, the problem is that i install as Refurbish the same version that i was running, the h815p v20a, but when it finishes it says rebooting, but in the device is boot looped at lg logo and powered by android, the phne used to boot and show desktop, now is bootlooped, what else can I do to make him boot?

If the phone is still recognized on your PC, see if you can get into download mode. If you can, try re-installing the KDZ from there. Make double sure it is the same kdz that was installed on your phone when it worked.
The other option is to see if you can get into recovery mode and try a factory reset.
It is possible that the freezing you were experiencing before when it booted up was, as raptordd suggested above in post #4, an early sign of the hardware bootloop issue that has now manifested fully. The only real option then is to send it in to LG for repair and tell them your phone, you believe, has developed the hardware bootloop issue. Even if out of official warranty, they should replace the motherboard in that case, at no cost to you.

Now that u mention that, the phone was recognized by pc, but i installed a lot of kdzs, and none of them made the phone boot, every one of them were for h815p v20a, the one that was installed, but now i connect it to pc and then says download mode but doesnt enter and then the lg logo appears again, even the charge is meesed up now, i think i screwed the download mode and the charge mode, is that possible? but i tried the factory reset when i had the working firmware but the problem persists. Now im thinkin my only option is to use a octoplus box to revive it, but dunno if that will fix the restart problem, about that warranty stuff, i can send it to lg mexico and they should change my motherboard for free? That sound too good to be true.

See if you can enter recovery using the hardware buttons and try executing it again.
LG has been replacing motherboards in a lot of cases where the issue is attributable to their own hardware issue (ILAPO). You don't really want to discuss the things you have done to get it working again with them ... if you get my drift, i.e., play dumb ...

Ok if none of the baove works, ill do that, but no, it has no recovery neither, not even stock, i read about a bootloader way to fix the download mode, im gonna try that but i doubt i can cuz bootloader is factory locked cuz is latin version.
No luck at all, phone is still bricked, is there any way to flash stuff via bootloader or abd without bootloader unlocked or root?

unbrick oneplus 5t, stuck in waiting for device in msmDownloadTool

Hi Guys,
Yesterday during an official update of my oneplus 5t (using the update manager from the phone itself), the phone got bricked and i dont know why....
So after some research i found it is hard bricked ( basically i cant do nothing, power on i cant, power +volume UP/DOWN too, and even when i plug the charge cable i have neither vibrations nor LED on)
So i follow this tutorial to unbrick the phone:
https://forum.xda-developers.com/oneplus-5t/how-to/oneplus-5t-unbricking-tool-confirmation-t3733012
I could get the phone recognize by the PC by pressing UP to see the phone as QUSB-BULK and then QUALCOMM QD LOADER after driver's update.
But when i run MSMDownloadTool ( V4.0.27 dumpling 43_0.36_180613) as administrator and click on start, the process get stuck in "waiting for device"
the status of connection before click on start was "connected" and after click and some process it turn to N/A
the status of communication is "memory size....."
status of last communication is "waiting for device"
I have tried several time and always the same result..... stuck in the waiting device
does someone have an idea on how to solve this? because i really need to unbrick the phone....
thank you in advance
EDIT:
I tried another version of MsmDownloadTool (dumpling_43_O.06_171206) and this time, the downloading of cache image failed....
I dont know what to do
You were in a custom rom or kernel when you tried to update from the official channel?
Your phone was rooted? Magisk installed?
Battery percentage?

Thing are much easier with the unlocked bootloaders!
Charge your phone all night long even if you don't see any sign of life (green or red led light).
Then hold together the Volume UP button and the power button for few seconds into the fastboot mode (hold both buttons for at least 10 seconds) and let me know.

I tried this before and nothing happened....
then when i connect to the pc by pressing UP+ power button, the pc detected it as QUSB_BULK then i install the qualcomm driver and finally i could see the phone in the usb device.
But after MSMDownloadTool step, the process got stuck and display "memory size" as explained in the thread.

Follow the instructions for the adb drivers installation.
Once done that, let me know

I know this is an old thread, but I'm hoping you have an idea. I have bricked my rooted OnePlus6. I did have Magisk installed. Bootloader was unlocked. I was able to factory reset the phone, but the bootloader was still locked (I had TWRP installed and factory reset using it). I then used Fastboot to relock the bootloader, and that's when my troubles started. I could only get into Fastboot. I found a solution on the web, installed the Qualcomm drivers (and they recognize my device, which I connected by holding down the volume up button before connecting to the USB cable), and started the OnePlus 6 (MSM) unbrick tool. However, it just sits there saying "waiting for device". I actually seem to have two entries for the device, one saying Index and one saying "1" (although I think the device is on COM3). Should it take forever? How can I get it past "Waiting for device". Thanks.

I contacted OnePlus and I sent them the phone and they reinstalled the operating system. I was never able to fix it myself. I even had an online session with OnePlus and they couldn't get the MSM software to recognize the phone (even though it was truly connected to my laptop). I also had an issue with my OnePlus 8T that got messed up doing something with Magisk, and OnePlus reinstalled the operating system as well. I still can't boot from the A partition though; just the B partition.

Okay, for anyone facing same problem as me, i found solution (working for me). Before using MSM Tool, you need to install Qualcomm USB Drivers.
During instalation you need to choose second option "ETHERNET-DHCP"!
At first, I chose WWAN-DHCP - which caused problem with connection
