How to Install TWRP on LG G3 Bootloop - G3 Q&A, Help & Troubleshooting

Dear all
My LG G3 started to get bootloop and I'm looking for a way to install TWRP that might fix the problem. I know how to install TWRP if it boot into the OS but now it can't boot. Do you know a way?

Flash it by fastboot

adb or fastboot doesn't recognize my phone. I put my phone in download mode, is it correct?

USB-debugging is allowed?

I don't know as the phone can't boot up. Therefore, I can't check or turn it on. Am I stuck?

Clearly you can't check it now. But do you remember that you made developers options visible? Anyway.
1. If USB-debugging is allowed, look on PC-side: does OS give a connect-message when G3 plugging in? ADB-tool ok?
2. Otherwise try to start over by flashing firmware.

When I connect my phone to PC in download mode, a driver fail to install (LGE Android MTP Device). I'm not sure if this cause adb not to recognize my phone.
For the 2nd option, Will my collection of data lost permanently?

1. ADB doesn't install device drivers. So take care, that OS connects correctly with G3. Then ADB will succeed.
2. Probably yes.

Bootloop is caused by hardware failure. I fixed it.

Fastboot mode Started - help

So this morning i thought it would be a great idea to revert back to stock.
i was following the KDZ lg flash tool however while it was flashing (got to about 2%) i stupidly knocked the phone and the usb cable came out....
so now when i turn my phone on it goes to a black screen with
Fastboot mode started
---reset---
---port charge--
i have tried going into download mode again but it still goes into this fastboot mode.
i found a lot of threads on this such as
http://forum.xda-developers.com/lg-g3/help/tutorial-fixing-fastboot-mode-started-t2995854
this got me to install adb/fastboot which i did via
http://forum.xda-developers.com/showthread.php?t=2588979
however when i try and run through fastboot it just comes up as waiting for device
i have attempted to install lg drivers for this but still nothing.
inside device manager it comes up as
other devices - android?
so clearly the computer is recongnising it, i just need a better driver.
I have the ldf ready to go, if only i could get it to recognise the fastboot command...
anyone able to help, i realise there is a lot of information on the web for this, after extensive research everyone seems to suddenly get into download mode each time. which is something i cannot go. and no recovery doesnt work either.
other things to note, just to save questions..
i am running LG D855 16gb.
when i attempt to go into recovery it comes up with the option to wipe device, but when i follow through menu comes back to fastboot mode started.
i attempted to install lg pc suite in hope that it would suddenly pick up the device and go through the fix upgrade errors (to no luck)
so to clarify, i cannot get into recovery, or download mode. my screen is sat on fastboot mode started.
i am running windows 8.1 although i have attempted to plug into a laptop with ubuntu but same story.
any suggestions? i have also seen a through about jtag...but i dont have any screwdrivers at this point so trying to avoid that.
thank you for reading, kind regards
Anyone out there that has any idea on how to fix?
im convinced i just need to turn the "other device - android" into something that can be recognised by adb, but other then the stock lg drivers i dont have anything else.
help?
FIXED - figured it out, i plugged it into ubuntu again and noticed that when it was connected it came up under fastboot with "accepting commands"
i then put my laf.img file into my home folder and
opened terminal
sudo su <enter>
fastboot boot laf.img
phone then went into download mode
as i didnt have any tools installed on ubuntu i then unplugged and plugged into my windows laptop and ran LG Flash tool 2014 and flashed my kdz.
hope this helps anyone who has the problem in future

Big problem

This may be a huge one. Someone accidently resetted my phone. Now i had to start from the start menu. When I connect the wifi after it gets stuck on "checking for updates." So then I wanted to reinstall the rom from via twrp. Now I find out im stuck on this because I have no back up and no extra roms to flash. So I tried to connect to my pc but my phone has issues with connecting on pc. It does not even show up on device manager. No unknown devices no exclamation point. Only way I know it connected is when I disconnect it makes a disconnect sound. Any help? I tried fastboot its a no go, adb sideload just loops on loading, and just recovery and it does not work. Any help please I need this fixed asap.
try to connect on usb2 port. I have similar problems when connected to usb 3 port on laptop or desktop.

Delete all the installed drivers relating to the phone and then connect the phone. Necessary drivers will be installed. If not solved, try another PC, cable, USB port etc.
usbdeview from nirsoft might help you to clean your driver.
When you connect your phone to your computer, is it on fastboot or on recovery ?
You should grab adb and fastboot driver (i'll upload them if needed), go to fastboot and plug your phone.
If you type from command line fastboot devices you should see your devices. If not, driver issue.
If you see it, then flash the official recovery : fastboot flash PathToRecovery\name_of_recovery.img, then sideload latest OB through OP recovery.
I don't know if its the faster option, but its easy as f*ck with that way to come back nearly stock. After that, you could flash twrp and the rom you want.

my pc has been recently resetted its on windows 10. theres no new drivers on it i checked on device manager.
By the way i did bypass the checking for updates. If anyone has a problem go to emergency call and type *#812#. Now I have a situation where I cannot hear anything from music apps. Can anyone help me with that? I tried installing viper4android, Dirac was crashing but not anymore, I installed magisk to fix it, i checked for audio_effects for bak file but nothing just the original. Any help?

Get back to stock and don't use mod, or use a stable ROM. Nitrogen 9.0 ROM havn't got issue with sound.

No ADB. No TWRP. No Magisk. Am I screwed?

Basically, I installed Havoc OS, tried flashing a couple kernels, kept getting systemui crashes, so I decided to dirty flash HavocOS again, and forgot to flash TWRP again before I exited TWRP.
Next, I boot back into my phone, opened Magisk Manager to find that Magisk is not installed, just the manager. I can't install Magisk as I have no TWRP...Which leads me to my next point, trying to boot into recovery brings me no avail as I forgot to flash TWRP. I have zero recovery right now.
Thirdly, HavocOS Suffers from the whole issue of needing SELinux set to permissive, for ADB to work...I can't do that, because I don't have Magisk/root.
Please tell me that someone has an idea here? I'd like to get TWRP back, or back to 100% stock and I can start over, or something other than a custom rom with serious SystemUI crashes and no root...
SOS!
This is not even close to a softbrick. Just boot TWRP using Fastboot and flash the zip from inside TWRP to install it. Also, there are various other solutions to fix your problem. Another one would be to simply use Deuces Recovery Script and go back to Stock.
As d-m-x stated boot twrp with fastboot boot not fastboot flash. Twrp will load into the phone then you can flash twrp and magisk.
I'd tried Fastboot already, will try again momentarily though.

Fastboot hasn't worked either. Unless I'm doing something wrong, but I just get "waiting for any device" despite having adb on/off, being in bootloader/fastboot mode or being booted into android, etc.
For Fastboot to work you have to be in the Bootloader Menu. How did you unlock and root your Phone in the first place? That should have taken you through those steps.
Anyways, it's likely that the computer just doesn't recognize the phone. Connect it and go into your Device Manager and see if it's properly recognized. If not install the correct USB Drivers and try again. If everything is set up correctly you can type "fastboot devices" while in the bootloader and you should see your Devices address which means it is connected and ready. Then boot TWRP as stated and install the zip from within.

Bootloader is unlocked etc. I initially did everything using the P2XLToolskit 2.0
You're correct, I think its simply a case of the PC not recognizing the device. I've already checked device manager, and it's not properly installing the device. I've multiple times tried reinstalling the universal driver, and various other fixes. I think it relates to the whole issue of HavocOS being screwy about USB. Many people have reported issues with USB recognition issues when ADB is turned on. The consensus from how I understand it, is that ADB ON = Phone won't be recognized. ADB OFF = Device should be recognized for file/data transfer...However even with ADB off my PC is still not installing drivers properly / recognizing the device.
The Device Manager lists my device as "Unknown USB Device (Device Descriptor Request Failed)"
Also tried:
1. Go to C:\Windows\INF
2. Find the file "wpdmtp.inf"
3. Right click the file and click 'Install'
4. Once that is done, simply plug your phone and it should work.
^ did not work.

Try these troubleshooting steps:
- make sure you're running the LATEST SDK Tools
- Try diff USB cables (switch from 2.0 to 3.0, or vice versa)
- Try a diff USB port
- Make sure you're in the proper fastboot folder with the fastboot application
- Boot into bootloader type fastboot devices see if you get a serial number
In my sig is a link for troubleshooting, and step by step that includes links to get latest SDK Tools.
If all else fails, I'd reco a fresh factory image install and get back to your cust Rom from there, rather than spend a day or two chasing ghosts.
Good luck!

Spoke with Google; getting the phone RMA. Blatantly told the guy it was rooted previously, bootloader unlocked, and running a custom ROM. He said it didn't matter. I will report back on this thread once I have new phone in hand, just to confirm all went well.
Reporting back.
Brought phone to virgin mobile, obviously still heavily modified.
Was given a loaner phone. Signed a paper saying I'd pay 150 for the loaner if it broke. Broke loaner screen same day.
Just picked up a brand new pixel 2 xl they shipped (phone only) because mine was considered unrepairable. I was charged 169 for the loaner phone, to my account with virgin. No cash transaction.
All in all, they honoured googles view of not minding the modifications so long as it's an issue they don't feel is related.
Cheers.

Bricked already, Access to Fastboot. EDL Mode Seemingly Inaccessible.

I hadn't tried rooting my phone until recently since I didn't trust myself, should have gone with my gut and waited longer since this is the only half decent phone I've got. I tried flashing mauronofrio's magisk patched boot image for 10.0.3 without realizing my phone had updated to 10.0.5. I didn't think to fastboot boot because it's been so long since I've rooted a phone. Afterwards, all of my network protocols such as wifi and mobile data no longer worked and although I could text, I could not call or receive calls. So, in an attempt to fix the issue, I used the experimental TWRP via fastboot boot in order to flash 10.0.3 since I could not find a boot image for 10.0.5 which didn't work. Then, I stumbled upon this post and downloaded the pre-compiled files with which to flash the stock fastboot roms. Obviously, I was very upset with myself for failing to read and process this information thoroughly enough and for that very reason I ended up making a far more rash decision in order to repair this issue. I ran the flash-all bat once with no difference, and a second time to get stuck in a bootloop. I have access to fastboot and the stock recovery, I can fastboot flash still, but I haven't been able to come up with a solution. If I did, I wouldn't trust myself to carry it out without confirmation from someone else. Anyone feeling generous enough to help?

I had a similar, but not as terrible experience when first attempting to get root on the 7T using the patched boot images that you used. I tried several other patched boot images, but none of them would allow the device to boot. I downloaded the full update of 10.0.5, then extracted the boot.img and it allowed me to boot the device again. Then I patched it in Magisk Manager, and everything went fine and I have root. If you have fastboot access, you can try booting your device using these images with the command fastboot boot boot.img or fastboot boot magisk_patched.img to see if your device even boots up from the images. I got stuck booting from partition b at one point, and used the command fastboot getvar current-slot to see the active partition, then I used the command fastboot --set-active=a to set partition a instead. If those commands fail then you need to update to the latest adb and fastboot and the commands will work.
This is the stock boot.img for the H1905 7T update version 10.0.5:

This is the Magisk patched version of the same boot.img:

My first try with the unbrick tool didn't even sense my phone. I saw the FAQ and then tried to find the Qualcomm drivers in my device manager to no avail, although I did find Kedacom drivers which I could not even attempt to flash over since Windows told me that the driver I was trying to push was out of date. Here is my original post on that thread:
Raeffion said:
I see neither QDLOADER 9008 nor QHUSB_BULK in my device manager and my device is not detected by the MSMDownloadTool. I do see, however, a Kedacom USB device in my device manager titled "Android Bootloader Interface". I just want to be sure that I should download the driver you provided onto my phone before I brick it any further.

As you can see, I did not yet mention that I still tried pushing the driver since I haven't had a reply yet. I don't want to double-post there but I'm getting no luck elsewhere. I really want this tool to work, is there some way to force push these drivers or is that a bad idea? If it is, any other ideas?
EDIT: Nevermind. I think it's bricked pretty good, I'll probably have to give up on this. When I plug it in, it only goes to bootloader, doesn't boot into recovery, system, or even show the battery percentage when charging. Bootloader hasn't been giving me many options either since the commands I've tried aren't going through. Updating ADB right now, don't know if it's likely that it's causing issues right after I already updated it.

Yeah, tried it again for good measure. Is there any chance I could get this issue resolved spending less than $100 by sending it to a OnePlus repair center or elsewhere? I'm not sure they do software repairs such as this, I didn't purchase a warranty since I figured I'd root this phone and I no longer know my IMEI since I can't access the phone to check.

Ive never sent my devices in for service so Im not sure about that. The fact that you have access to fastboot still though makes me think that you arent totally screwed yet. When I had stuff go wrong and I went to use to MSM tool, I didnt have the proper drivers installed, and my device never showed up in device manager. After installing a different set of drivers and rebooting my pc, the device showed up in device manager under the Ports section. I was able to get back into my device without the unbrick tool by switching the active partition. Did you say you already checked your active partition with command fastboot getvar current-slot? If you are on slot a, have you tried setting slot b as the active and seeing what happens? This is the command fastboot --set-active=b.
Here is a driver for the unbrick tool to recognize your device that might work for you. https://www.dropbox.com/s/lgt1qanfqs8pvbe/QDLoader HS-USB Driver_64bit_Setup.zip?dl=0

I did try setting the active partition to slot b as well, I was getting pretty much the same errors as attempting to boot from an image file. Although, I just now tried setting the partition to b and it worked. I'll try rebooting the phone to partition b now as well.
EDIT: Thankfully, setting the partition to slot b worked! My phone now has access to system and recovery once again and boots as normal. I am still in a bootloop though, so I'm attempting to install the drivers now.

Awesome, installing those drivers right now. The link provided in the beginning of the thread for the MSM Tool just wouldn't work for me since my device was detected as something that wasn't mentioned in the entirety of the thread so I couldn't install it directly via device manager as directed. This should hopefully get me up and running on the tool, I'll update this post once the drivers are installed hopefully.
EDIT: I installed the driver but nothing has changed from before. The MSM tool still doesn't detect my phone, I made sure it was run as Administrator. My device drivers are still Kedacom which I attempted to update the driver using a file on my computer once again and Windows wouldn't allow it. Am I simply looking in the wrong place to manually install this driver? My device manager is set to view devices by type and plugging in my phone causes only the Kedacom USB device to appear, so I assume I don't have QDLOADER 9008 or QHUSB_BULK devices listed there. I can provide screenshots of my device manager window if it helps.

EDIT: Thankfully, setting the partition to slot b worked! My phone now has access to system and recovery once again and boots as normal. I am still in a bootloop though, so I'm attempting to install the drivers now.

Hooray! Almost haha! It is the worst feeling when you mess up your brand new device, but as long as I have fastboot I dont stop trying to fix my mistakes. You should be able to fix it for sure.

Awesome, installing those drivers right now. The link provided in the beginning of the thread for the MSM Tool just wouldn't work for me since my device was detected as something that wasn't mentioned in the entirety of the thread so I couldn't install it directly via device manager as directed. This should hopefully get me up and running on the tool, I'll update this post once the drivers are installed hopefully.
EDIT: I installed the driver but nothing has changed from before. The MSM tool still doesn't detect my phone, I made sure it was run as Administrator. My device drivers are still Kedacom which I attempted to update the driver using a file on my computer once again and Windows wouldn't allow it. Am I simply looking in the wrong place to manually install this driver? My device manager is set to view devices by type and plugging in my phone causes only the Kedacom USB device to appear, so I assume I don't have QDLOADER 9008 or QHUSB_BULK devices listed there. I can provide screenshots of my device manager window if it helps.

On my pc, I didnt have any issues with the drivers, but when I was helping a friend over TeamViewer trying to do the same thing you are trying to do, the drivers just didnt help no matter what and it wasnt listed in the device manager. I was able to make it show properly on his pc by using the steps explained in this article. https://docs.microsoft.com/en-us/wi...boot-configuration-option?redirectedfrom=MSDN After restarting his pc, the device showed up properly in device manager with test mode enabled.
Are you able to access adb now, or still only fastboot?

I embarrassingly don't even really remember all the specifics about how ADB works, although I don't think I have access since I'm in a bootloop when I launch Android. Unless I have access to ADB via fastboot or recovery, I don't think I do.

Yeah I had no idea what Windows test mode was. Before I rebooted just now to install the drivers you provided, I actually launched into Windows test mode with no command from me telling Windows to. I thought Windows invalidated my license yet again tbh, glad to know it didn't. I don't think I'm in test mode now, so I'm giving that a go right now. My computer takes a while to warm up so I'll let you know the results in a bit.

It will just make driver installing issues less likely. When you boot your phone, what happens on the screen? Does it get stuck on a certain screen or just restart over and over? You can see if adb can see your device with the command adb devices, and it should list your device. If not, try fastboot devices and it should be listed. You need to put the device into EDL mode for the unbrick tool to work, and for it to be shown in device manager. My friends device manager listed Kedacom just like yours, and I didnt do anything to that at all. I just used test mode, installed the Qualcomm drivers, put the phone into EDL mode and the unbrick tool should recognize it. If your phone is listed when you type adb devices, you can use command adb reboot edl to enter that mode needed for the unbrick tool.

Sadly my drivers haven't changed. I uninstalled and reinstalled the installation file you gave me since I first installed it via WWAN-DHCP instead of ETHERNET_DHCP. I use a VPN so I figured that may have affected the installation, although for some reason I didn't think to just turn off the VPN when I reinstalled. Regardless, I don't think my VPN or the way I installed the driver is the cause of the drivers mentioned not being found in my device manager, so I'm likely not going to bother.

Another problem that can cause your phone to not show up in device manager is the usb port you are using. Have you tried any other ports? Are you able to shut your phone all the way off by holding power until it turns off? If you can unplug the phone and turn it off, then hold the volume up and volume down buttons together, then plug the cable back into the phone and it should put it into EDL mode.

It just shows the boot animation, it doesn't restart.

ADB shows no devices attached, fastboot shows my device.

I seem to have been missing a vital part of information. I don't know why the term "EDL" just went over my head, I probably just associated it was fastboot mode when I looked it up. How do I get into EDL mode? Is it safe to assume the method listed here works for the OnePlus 7T?

Fastboot mode and EDL mode are two different things. I have never used the fastboot to EDL method, but I have read about it and I assume it should work atleast on some devices. Unplugging from pc and turning the phone off, then holding both volume buttons and then plugging the cord into the device should enter EDL mode without commands.

I must have assumed that it was fastboot mode since when I held those buttons and plugged it in, I'd always launch into fastboot mode. Perhaps it's different with the US version? That's the version I have.

The only version I have used at all is the US one. You could try holding both volume buttons for a few seconds before plugging the cable into the phone, but if that doesnt work you can try the fastboot to edl method. I have no experience with it at all though so I dont know if it works with this device or not, but you would just open the edl.cmd file and it should put the phone into edl mode.

It just boots me into Android sadly. I don't know that there's any way to get into EDL mode for me. Possibly due to my use of the experimental TWRP and mauronofrio's Stock Fastboot ROM tool.

What happens if you use command fastboot boot boot_stock_10.0.5_US.img using this file?

No dice.

PC No Longer Detects Phone After Rescuing with Stock OTA File

My problem started when I attempted to bypass the FRP by flashing a custom TOT file. I neglected to notice the file was specified for a 32GB version. I flashed it on a 16GB version using LGUpgrade Tool. The phone then froze at the splash page that just says "Google" . I thought I was fortunate enough to be able boot to recovery mode and so I flashed the stock firmware through ADB - the same ROM version that was previously on my phone and from a copy which I had used in the past with no problems. Everything seemed to be working again except my PC doesn't detect the USB connection anymore. I've tried the same procedure but now the command 'adb devices' doesn't list the phone. However, there is a point when I boot to recovery mode the PC makes a sound as if it detects the phone but then moments later it makes the other sound as if it gets disconnected. As I stated earlier, my phone seems to be where I was stuck at FRP with Android version 7.1.2 but my problem now is I can't get the PC to detect the phone when it's plugged into its USB connection. Nothing shows in Windows Explorer as well as Device Manager? I tried re-installing the drivers. Stopping and restarting the ADB server... still no detection. Is there a way to set USB mode to MTC while in FRP mode? Should it matter in Recovery Mode?
I'm going to wait for a response before I attempt to flash again but this time through the SD card because this will be a first time for me using that method and I hope there's a less risky solution.
