LG G3 in download mode not detected by Windows - G3 Q&A, Help & Troubleshooting

Dear xda-developers-community,
I'm trying to get a phone of a friend of mine working which just reboots whenever the phone is started. The resulting boot loop can only be interrupted by taking the battery out or wait until it is depleeted.
In order to fix this soft-brick I first tried to use recovery by pressing VOL - & POWER. In the menu, I could select and confirm to recover to factory settings, but after some seconds the boot loop appeared again with (seemingly?) no change having been made. The error kept appeaing over and over again.
After trying recovery mode, I attempted to start the phone in download mode by pressing VOL + on the (switched off) phone and connecting a USB cable. The respective menu also opened, here, showing "Firmware Update" and "Do not unplug the USB connection until the process is complete". According to many tutorials I found on the internet, when having installed the required drivers (I used LG United Mobile drivers from here), this procedure should allow you to flash a recovery image through LG's flashing tool (which one can also find on that page).
However, when I connect the LG G3 (D855) to a computer the driver is installed on, there is no new device shown in the Device manager. I tried this out with Windows 10 x64 and Windows 7 x64 and disabled driver validation on both systems and enabled test signing on Windows 10, respectively. Additionally, I followed these instructions, but in this case the screen stays dark and the device is not detected either. It seems like there are not so many people experiencing this error, but I hope we can find a solution.

This may sound like a dumb question, but have you tried a new battery yet? If it is one of the original batteries it could have gone bad & started bootlooping...like mine did a few months ago.
As far as the PC not recognizing the phone you can try downloading USBDeview and uninstall anything that has the vendor ID's of 1004 & 18d1(pretty much anything that says android or LGE in the description) & reboot the PC. Hopefully it'll recognize your device and install the drivers the next time you plug it in. If it doesn't find the drivers automatically for you then install LG drivers manually.

Good luck :fingers-crossed:

[Q] Download Mode / USB Drivers not working

Hey there,
I press volume up + insert the USB, when the LG screen appears I let go of the volume button and leave it. After roughly 1 minute it says Download Mode however it only stays in this mode for roughly 20 seconds and then it goes into Fastboot mode saying "reset" and "changed port". I got the correct ROM for my IMEI and LGFlashTool however I think the main problem could be the LG USB drivers. When I try install the official drivers the installer says success however windows says not successful.
Image 1 - i.imgur.com/hPkZbLx.png
Image 2 - i.imgur.com/nxdYm39.png
I have tried uninstalling all LG drivers/software, restarting etc.
I am fairly sure I can flash if I can just figure out how to successfully install the drivers or connect the phone to the PC. Anybody have any ideas? I can use linux or try any suggestions/alternative software.
Kind regards,
Desperate G3 owner
Just an update that I was able to manually apply the LGE PORT/COM driver in device manager however the PC only recognises the device when it is in Fastboot Mode. When it starts in Download Mode as stated above, nothing happens, but after ~20 seconds it will automatically switch to Fastboot Mode and then the PC will detect the phone and says Fastboot Commands.
I have tried using adb.exe devices and fastboot.exe devices in cmd but nothing shows up, any ideas?

Boot loop after OTA upgrade

Hi everyone, today my Elephone p8000 with stock rom (no root nor recovery installed) proposed me an OTA update, and I did it.
After installing the update the phone is stuck at the boot animation logo. If I boot in factory mode (volume down + power button) I am presented with a bunch of options in Chinese, which I don't understand. If I go in recovery mode (volume down + power button) it says "no command".
What can I do? What are my options? Is it bricked?
Yup mine too. Mine has root, with no custom recovery. Get the same boot loop and the sad open Android 'no command'.
Haven't had a chance to dig around for a solution but I suspect it is a case of using the flash tool to wipe and load a standard ROM? Hopefully an easier way.

Damn. I had huge problems with the flash tool in the past (I don't have a Windows PC) and the idea of spending the weekend trying to get the damn thing work is not a fun one.
Got this issue too this morning on way to work, I guess my phones useless today until I get home to try and flash it.
seem to be able to get to the boot select screen but nothing is different anyway, also managed to get into a "PCBA" mode that did a load of tests to the phone but thats it.
it now just died, not powering on, think its bricked :crying:

Probably just out of power. Try charging it for a while and/or download and flash entire rom using sp flash except for data-partition so as you don't lose your data.

I just had the same problem. Did you solved it?
Like, exactly the same... Crazy
Another one
My p8000 also in bootloop after ota update. Only have an old vista PC w8ll dust it off tonight and see what happens
mines doing the same i thought it was too good to be true and it was lol
Cannot get pc (win 10) to install all the drivers, PC cannot see the phone so unable to run flash tool.
Suggestions? I presume the ROM cannot be flashed through the recovery (standard)?
EDIT: Driver package installed by disabling 'driver verification' setting in Windows. Phone only recognised as a MTP USB Device in devide manager, and flash tool does not seem to want to do anything. Might try this on a Win 7 laptop tomorrow. HJow you guys getting on with this?
Success - I Have a Working Phone
(or, How Chest Pains and Rage Focused the Mind)
So. This is what worked for me. Win 10. P8000 bootloop.
1) put p8000 into recovery, chose 'power off'. (I couldn't seem to stop it rebooting using the power button)
2) installed driver pack by disabling the Windows install signed drivers only setting. Rebooted. This turns the setting back on, but the drivers have alrwady been installed, no issue with that.
3) installed the flash tool. Brief panic at Chinese chars, located English. Calmed down.
4) loaded flash tool, with ROM ready to go.
5) this is the biggie, this is what brought it all together.........connected the powered down p8000 via USB and IMMEDIATELY hit the download button in the flash tool - ie BEFORE a new instance of USB bing-bong-device-connected sound.
6) once all downloaded, disconnect phone, reboot. Took an extended time (few mins) to boot, enough time to almost start swearing under my breath, but it just needed some patience.
Now, what I spent some time unsuccessfully trying to fix - needlessly as it turns out - was what my phone appeared under 'Device Manager'. It still lists it as an MTP USB Device under the 'Portable Devices' submenu. It did not seem to matter, as long as all the driver were installed.
I wish you all the best of luck in solving your issues, hopefully some of what I wrote can be helpful.

I have the same boot loop after ota. I did no backup before, so data partition contains my apps right ?
I never used the flash tool , where should I start , any good link for beginners ?
I read some things about the flash options months ago, must I disable/uncheck some options ?
Thanks for help.
same issue
Hi everyone!
I've got the same issue: I allowed the OTA update to 20151105 firmware release from previous version (20150725), after the upgrade, the phone keeps in a bootloop with a new colored Elephone logo.
I can't find a valid set of drivers, I tried a lot over the night, but windows don't recognize the phone.
PLEASE some kind soul could link a valid driver package to use SP tool ?
thanks a lot in advance!

pretty much did the same thing and it worked!! Cheers!! (also had the rage and it took ages to find english on the tool lol :laugh: )
when you get the android with the "no command" message, let go of the volume and power buttons. Then hold the POWER BUTTON for 1-2 seconds and TAP VOLUME UP while still holding the power button. this will open the recovery options
omg!!
disabling the Windows install signed drivers only setting!!
i thought we wouldnt have to do things like this since Windows 95
Lol
Worked for me
Had I only found this tutorial before yesterday... it took me hours to figure this out.
I can, however, now confirm this works.
Regarding point 5):
(i) Power down phone (ii) start flash tool/go to download tab (iii) select scatter file (iv) hit "download" with no phone attached (v) attach the powered down phone
...and things will be fine. Doing anything fast is not required.
The point is to install SP_Drivers_v2.0 first, as described here. After this, everything goes smooth.

What if no Windows?
Edit: Never mind, I got myself a windows computer and succeeded. Thanks for all the orientation!
Hi all,
Thanks a lot for posting a solution to this problem so quickly. I am affected by the same issue. Looking to buy some LSD to better enjoy the psychtrip my phone seems to be stuck in. Also looking to fix the phone.
Unfortunately, I'm running Ubuntu 14.04 LTS. I did find a guide to use the flash tool on Ubuntu, but my phone does not seem to connect. I'm guessing this has something to do with that pack of drivers 2.0, for which I have no equivalent. I would really appreciate any ideas!
I might end up returning my phone to Amazon, though. It's only been a few days since I've had it, and you can imagine that although I was really liking it, I'm beginning to change my mind.
Your advice?
EDIT: I am getting the following error message:
BROM ERROR: S_COM_PORT_OPEN_FAIL (1013)
[COM]: Failed to open COM port.
[HINT]:
I did some googling, but didn't find anything worth mentioning.

Ahh good stuff. Connect phone last after hitting download - thanks for the heads up. Got my wife's p8000 today so will be doing some flashing later.

Bricked Swift

Hello Everyone!
I recently tried to root my wileyfox swift but failed miserably. I did the following when fastbooting the recovery image -> fastboot flash system ****.img.
However, i realized my mistake too late, and now my phone is all messed up!
The phone doesnt show anything when i try to start it and i cant access fastboot again, to undo my mistake. My device manager recognizes my phone when its plugged in to my computer but i cant access any files.
Am i screwed or is there any solution to this?
Thanks in advance!!
Try to access the bootloader with the hardware button combo first (volume down + power / volume up + power). If you get into recovery, you will be able to get to the bootloader with adb or a menu entry. Depends on what recovery you have installed for the latter.
In case you have no access to the bootloader (proper soft brick), go for the QFIL method. Avoid using it unless there is no other option.
Here is the thread:
http://forum.xda-developers.com/wileyfox-swift/general/how-to-set-device-tampered-to-false-t3276317
Cant access bootloader.
However, tried your second option and it went well until i got "SaharaDownload fail" at the last step, and now my computer doesnt recognize the phone in device manager. It does not show anywhere that my phone is connected.

Does the phone give any indication of being connected? Notification light, starting the display, etc?
If yes, make sure the phone is in the correct mode and check the drivers - some of the other forum members mentioned this and the gymnastics around the battery. This would be on my to-do list. The device might come up on the device manager as different one, so monitor the manager for any changes once you connect the device.
If you happen to have Windows 7 device laying at you house, you can try with it (if only not to worry about compatibility and sporadic Win10 behaviour).
It will be a good idea to check the turkish website for General Mobile 4G (one of the Android one derivatives of the hardware) where some people have faced similar problems using the same tool.

Bricked my LGG3

Hello everyone,
so here's my problem:
Wednesday morning i took my phone out of my pocket and had a blackscreen. I tried to restart it and took out the batterie but i always got stuck in the LG Logo or a bootloop. Since i had TWRP and lineage OS installed, i tried to go into the twrp menu with the factory mode (power button + volume down) but after the "double yes" i always got a blackscreen.
So i went into the internet to fix it myself. I tried the "LG Flash Tool 2014" with the kdz. reset & the other Flash tool with the tot. reset. Both didnt recognize my phone. At this point, the only thing that worked was the download mode BUT not the recovery mode that usually comes after it. It just showed the download mode for some seconds and then a black screen. Later i noticed that my phone showed as a "qualcomm device" in the device manager, and the internet said that this was bad. So i used "Board diag" and "Smart boot diag" to fix it, but at the point where the device should have restarted, and the download mode should have worked WITH the recovery mode, i always ONLY had the 6 second download mode. After messing a bit with "Board Diag" i even got it to show up as LGE AndroidNet USB Serial Port in the device manager, which apparently was even more bad and only way to go back to qualcomm was to shorten the pins which i did. And it worked BUT now i was back with the qualcomm stuff.
So as you can see, i've prety much run i circles since wednesday... Iam now at a point where 3 different thingscan happen when I try to put my LG into download mode (volume up + usb cable):
1. Its recognized as a unknown device which is constantly connecting and diconnecting, so iam assuming my phone is bootlooping with a black screen.
2. The download mode icon shows on my phone and disappears after some seconds but my pc fails to recognize it.
3. Nothing happens and the screen stays black
When i only connect the usb cable, it shows a stuck charging icon for some seconds and then goes black. Connecting without a battery shows the "missing battery icon". I tried with 2 pc's, both having the LG mobile driver 4.2 and the qualcomm driver installed AND beeing in testmode. Both don't recognize the device. I also tried 2 batteries on my phone but it changes nothing.
I have a D855. And i know that my situation is pretty f*cked but maybe someone i able to help me anyway. Thanks alot.

Phone Not Entering DA mode.

So Here are the steps
1. My bootloader got unlocked.
2. I Installed factory preloader and lk images.
3. Rebooted to Fasboot and flashed TWRP 3.3.1-0924 by wzsx150 (the only Android 9 recovery that didn't get removed immediately after flashing and rebooting for 1st time to get to recovery).
4. Formatted Data, Closed AVB 2.0 and Signed TWRP.
5. Rebooted to Fastboot and flashed stock EEA Android 9 (11.0.3.0) from Global (11.0.6.0) and reflashed factory preloader and lk.
6. Rebooted to recovery, Formatted Data, Closed AVB 2.0 and Signed TWRP.
7. Using ADB sideload from Twrp Installed EEA Android 10 (11.0.2.0).
8. Rebooted into fastboot Installed Updated TWRP-3.3.1-1210 (by wzsx150).
9. Rebooted into fastboot and flashed misc.bin from same zip (according to bat file inside it should get flashed after recovery but I forgot.)
10. BRICKED. Booted to Redmi logo for 3 seconds and rebooted infinitely.
This type of brick in 4pda.ru according to google translate can be mitigated by letting battery drain and then enter DA download mode using SP Flash Tool.
I've Used the tool several time so I thought Okay no big deal.
So This is what I tried:
11. Pressed download button
12. Connected USB Cable to phone.
13. Device pauses a second (Probably for SP Flash Tool to respond) then doesn't enter DA (Unlike previous times) and screen brighten for a second or two but then turns off and repeats this process forever.
I've been using Drivers provided by Microsoft Update Catalogue but tried all the drivers on 'MTK Usb Driver v1.0.8' and 'Mediatek_Driver_Auto_Installer_1.1352.00' after disabling Driver Signature Enforcement. but even though drivers are installed they don't get loaded and after force installing them in add legacy drivers they are their but have yellow triangles and their Location lists as 'Unknown' and status as 'This device cannot start. (Code 10)'. Tried Removing them after adding them as a site suggested but that didn't work either.
I learned the hard way to never mismatch partitions with this phone. I thought having the factory preloader and lk1/2 would protect me but no.
When you say brick, do you mean you have a completely black screen with only the notification LED turning on when you plug it in?
Grab a bootable Linux image and use that on a USB stick to eliminate the driver issue you're having. Interface is identical

So I tried Ubuntu. Problem isn't from Drivers. It's because my Windows or linux didn't ever got a chance to enter fastboot so they can load preload drivers properly.
In Windows, Mediatek USB Port is the only driver that get loaded, and that for only an instant then it disappears in Device Manager.
In Linux according to this Tutorial everything is fine but SP Flash Tool gives me a " ERROR : STATUS_ERR (-1073676287) , MSP ERROE CODE : 0x00. "
Based on this chinese site I should find my Vendor Id and Product Id specific to my system (or is it my chipset?) and then change some files but how do I get linux to recognize mediatek usb device first when It needs to enter fastboot for that to happen.
Is there any way to manually add it?
EDIT: So After some reading I realized that I have to get my phone to fastboot first to get the drivers recognized. In windows as far as I know there is no way for manually adding 'Location' to Drivers. what about Linux?
I think you're talking about a soft-brick and I'm talking about a hard-brick. If you can get to fastboot, it's a soft-brick.
Hold the volume down and power buttons simultaneously for 1min and see if your screen changes.
Don't worry about the Linux drivers, if your phone is in the correct mode, it'll work.
I don't think it's a Soft-Brick (unless Hard-Brick means even the display not turning up at all), Holding them for a minute with battery charged doesn't do anything. As soon as it boots back up it starts getting caught in Booting until Redmi logo and staying there for 2-3 seconds then reboots. I tried to hold Volume Down + Power for 3 minutes while caught in this bootloop but no fastboot. I'll retry when battery discharges again. first without usb cable attached then with.
Thanks for taking time to work this through with me. Nowadays with all service centers being closed it's really a nightmare to have something you need on internal storage and not being able to access it. First thing I'll do after this is to buy a 128GB SD card to store the important stuff.
By the way should I just use the Live Ubuntu or Install it to see if the problem is from being a live image.
When I hard bricked my phone, I didn't have anything but that white led when I plugged it in. If you have the redmi logo, should mean there is hope. I've only ever entered DA mode when I had a hard brick.
This might be one of those situations where letting the battery drop to 0% would allow you to access fastboot. MiFlash only works in fastboot and DA mode I believe. What happens when you hold volume up and power for a minute while plugged in to your computer? Run "ADB devices" to start the adb service first
I doubt it would make a difference live to installed, but it's your call if you have the time.
With Phone in Bootloop mode Holding Either Vl+ and Power or Vl- and Power doesn't make a difference.
With Phone Off and USB detached It's the same.
With USB attached Vol+ and Power for over 3 Mins result in Device Manger listing 'Mediatek USB Port' for as long as display remains 'dark but bright' (for 2-3 seconds then shuts down and turns itself back on). removing it when phone suddenly shuts down. when USB is detached phone remains shutdown.
With USB attached Vol- and Power for over 3 Mins result in Phone's Display Brightening for 5 seconds no device listing in Device Manager nor entering fastboot or being recognized by adb or fastboot (set on a permanent re-checking by a cmd script). then phone shuts itself down and back on.
LED situation:
With Vol+ and Power with USB attached LED when phone is Off is Fullbright. When Display Brightens It turns off.
With Vol- and Power with USB attached LED when Phone is Off Blinks Once Fullbright and then remains Semi-bright whether phone is on until shutdown and the Blinks Fullbright again.
I Live in Iran and with sanctions there is no way to pay anyone overseas. Unless they're willing to risk accepting cryptocurrencies from an Iranian , my only chance if I can't work it out is to wait till unofficial service centers here open.
Your phone only being detected for 5 seconds is supposed to happen. It checks for a signal from so flash and if it doesn't see it, drops off.
I'm not sure paying someone to remotely flash your phone will work if SP Flash isn't even trying or detecting your phone. With mine, it would detect and try to flash (red bar sitting at 100%) before throwing an error.
Try letting your battery die, if that doesn't work, maybe the test point mod will work. Otherwise, I think your only option is a service center.
