For me, when I try the ZV9 root method, the cmd keeps saying "Mount: Permission Denied"
and other lines saying how the files are read-only or something like that.
I am on the new JB firmware (E97320H) that I flashed using the KDZ flasher.
Any help?
Usb debugging on? As well as unknown sources?
LG Optimus G E971/3/5/7
I had a similar problem, don't know if this will help but it worked for me....When it asks to change to MTP disconnect the USB cable, disable USB debugging, re-enable it, then plug the phone back in. Archie87 was the one who gave me this tip.

Here is a photo of the error.
WORKED!
I downloaded the ZV9-ZVB files from http://forum.xda-developers.com/showthread.php?t=2050582
IT WORKED LIKE A CHARM!
I guess the ZV9 files were not working, but the ZV9-ZVB files did.
Thanks to all those who helped

I realized I was not in download mode. Now i am currently downloading the factory image to flash
Hello,
I have LG G3 D855 32 GB not rooted, dropped in water but now it's dry, it was giving me a green screen says "kernel crash". anyways, i have installed the LG drivers on Win7, all the drivers installed except the MTP one to try to fix it through LG Flash Tool but it didn't communicate with the phone because the MTP failed to insatll, no luck with usb cable. I Don't know if it's possible to boot/install anything from Micro Sd Card?? I have the .kdz .tot .dll files for it
I would appreciate any help
Thank you in advance.
It's not possible to install any firmware directly from the phone. Try anyway to connect your G3 with your computer and use the LG Flashtool to flash a kdz or an tot file. If it isn't successful you have to send it to LG for repair.
MTP Failed
Thank you Der CaRl fro the quick reply,
the phone can go to firmware update mode, but as i said the MTP driver couldn't be insatlled. i don't know if there is a way to make the phone in usb debugging mode from pc by commands or something??

Did you try the download mode (hold volume up then plug-in to PC), wait til the PC recognized your phone, then flash your rom via lg mobile tool or update via server.

Thank you for the reply
Yes I've tried it, and this is one of the main problems, when i go to the download mode and plug the phone it keeps searching for the MTP driver and failed to install it. I've tried all the solutions on the internet but with no luck.
Recently after trying to upgrade my LG G4 to android 6.0 by flashing the zips in recovery, I encountered a boot loop. I have tried many thing like using the LG Flash Tool, I also tried booting into recovery and restoring a backup I made, but none of this made any difference. Please I need help.
LG G4 H815 android 5.1.1 or 6.0 (not sure) I'm not sure because I tried to flash the zips fro android 6.0 via recovery and didn't work, then I restored my phone and tried to boot up but that failed to work as well.
Try to use the LG bridge tool.
Start lg bridge.
Connect your device while off with your usb cable.
It will start - nevermind, just keep it going.
Use the "solve update issue" option in the bottom right corner of the software update screen in lg bridge.
It will reinstall 6.0 without data loss.

It does not detect that the device is connected, even when it is.
Takes some time to detect. Worked for me an hour ago...

I might have fixed it using a different method.
Wich method?
I have the same issue.. I send my phone to the repair center of amazon. Let´s look what they can do.
Not necessary, in bootloop, just connect usb and start lgup, when it detect it, (and it will as unknown mode device) tap com port it was found on and ui will open, then click on phone info, it will connect and establish a valid usb connection to phone and open new prompt with phone info...... Then start adb command prompt and enter 'adb reboot recovery' and bingo you're in recovery.... Solves every bootloop!

I've got an LG G Pad 8.3 and I deleted all my files with recovery (stock) by accident. And I didn't made a save from them. I want to recover my files, but I can't do this because it can connect to PC only by MTP and If I wanted to root it via adb, adb said my device is offline. Can anyone help me in this problem?

You mean you Factory Reset so that your internal storage were wiped, right?
There's probably some Android apps available to undelete files, but I have no experience doing so. You have USB Debugging enabled? Also, some LG devices have a solvable "bug" (at least after rooting) that after every reboot, USB Debugging is turned back off. If yours has that problem, the way to fix it is to turn USB Debugging on, hook the device up to the PC, change it to PTP mode, then back to MTP, then disconnect. From now on it should be good again until certain circumstances cause it to start happening such as after flashing a KDZ or TOT and then re-rooting.
Once USB Debugging and you try to access the device via ADB, you'll have to confirm the ADB authorization dialog on the device. Select the checkbox to remember the authorization.
Thank you

No idea what else to suggest. I'd probably have to be there and fool with it myself to get any ideas.
Did you look for any undelete apps in the Play Store?

Hi,
What kind of MTP workaround did you try?
Good luck...

Hello,
What happens in "Device manager" when you plug your cable in? Is it listed?
Good luck...
I was having an issue like this with my previous 3XL. It would say Unknown USB device (Device Descriptor Request Failed) . I tried multiple PCs and nothing worked. Ended up using my extended warranty and paying the deductible to get a replacement which is working fine.

all that is coming up is google nexus ADB interface, it seems like the drivers will not install properly. I cant get it replaced under warrantly as i had to get it second hand due to lack of money. It connects and windows makes the noise to inform its detected the device but no matter how many times i manually install the driver it does not work and windows does not seem to auto download the driver, this is something ive noticed on all machines I have
