"Couldn't open the port"

I have tried the LG G3 firmware root instructions. Everything seems to work until I get into the Firmware Update mode. Port.bat shows that the phone is on COM7, which is confirmed in the Windows 7 Device Manager. However, when I run the Send_Command.exe portion I am told "couldn't open the port"

Thoughts?

I faced similar problem. Just unplug your device and connect it again and then try. Worked for me.

If it doesn't works, then try disabling USB debugging and then re-enabling it.:)

[Android Q&A, Help & Troubleshooting] Sarakin:
OK, I have the ATT D-850 with 20F firmware. I tried Purple Drakes root tool as well and it tells me the phone is not vulnerable so it cannot get temp root, the unplugging and disabling usb debugging options doesn't work for unjustified_devs tool. I seem to be at an impasse.

Still no luck

Tried it again over the weekend with the 1 click method. After having trouble for awhile, I got to the part where it is supposed to run the root script and it just sat there with the # and cursor blinking after. Left it for 10 min and nothing happened.

Also tried to use the old method, no luck that way either. Any suggestions?

[Android Q&A, Help & Troubleshooting] doctazz:
It could, but some of the commands, like the Send_Command and ports checker are Windows only. The original dev would have to (or get someone else to) recompile or rewrite the source code of the Windows commands to work in Android or any other OS.

Has anyone noticed the benefits of upgrading to ZV5?

I'm only asking, as I tried to upgrade to it myself. At first, I didn't know that TWRP needed to be overwritten with stock recovery when I attempted the first time. I followed wajiema's (?) TWRP boot loop guide and was able to install stock recovery, then unroot. I copied the update zip from internal /cache to /download on the external SD card. I then tried to upgrade to ZV5. For some reason it didn't work. So I deleted the update zip and tried to get the phone to redownload the update. I read that post about using the Autorun Manager and Disable Service apps. Made sure those options that allow the update to download were checked. One of them was unchecked, and so I checked that. Then I rebooted, and waited a few minutes... nothing. Tried to copy update.zip back to internal /cache and then update. Again, nothing happened. :(

Right now my phone has been rerooted, and once again is using TWRP as recovery. Still on ZV4. I guess I can live with it for now. I usually prefer OTA updates installed, as long as I can have root access.

One other thing, I noticed that after installing stock root and stock recovery (and later rerooting and putting back TWRP), I can no longer update PRL, profile, Firmware, and UICC unlock under System updates. (Not that I need to do UICC.) This might be a problem if I need to reconnect to VM if the phone somehow falls off the network, and I don't want to (or can't) enter the usual info through their web site on a PC or tablet using my account. I would need to at least be able update PRL and the profile to reconnect the phone. Is there a hidden menu I can access for these options?

Thanks for reading.

flashed lg g3

So my phone is an LG G3 (VS98512B) which is verizon, but it is flashed for t-mobile and i was wondering if there would be any conflicts from trying to the one click root guide. Also, i dont have the original cable. Can i use any other usb cable to root or will that increase chances of failing?

edit: The root was a success! I installed both(LG VERIZON, LG) drivers provided, had to switch to PTP, and after watching the video i noticed i had to manually set my phone to download mode and reboot. All that with a samsung usb cable.

Download mode failing - VS980

I can't, for the life of me, get this method to work. I'm trying to update a Verizon LG G2 (VS980) that received the latest Lollipop (5.02) OTA update, and I always get to the step in which it's looking for a serial port. That detection fails, and so I'm instructed to manually enter download mode. I do so and get to the phone screen that says Firmware Update. Unfortunately, it fails to copy anything over at that point (percentage indicator remains static at 0%).

The bottom box on the screen says the following:

VUSER_G2 B24

MODIFIED

Not sure if that information is relevant. The "modified" is in red, which makes me feel uncomfortable. :P

Problem getting Windows 7 to recognize my LG g3 (LS990) over USB

I'm not very familiar with Windows and am running Windows 7 in a vm (inside VirtualBox on Ubuntu 14.04).

I'm pretty sure that VirtualBox is passing the USB device along properly as I have a Windows XP guest vm as well that recognized the device once I installed the drivers mentioned in the guide here (The reason I'm trying with Windows 7 now is that the guide in that URL wants me to look at the registry keys to get the com port for the device but no such key seems to exist in Windows XP).

When I tried to install the drivers in Windows 7, they install fine but when I connect the device and pass it through to the guest (windows 7), I get "Device driver software was not successfully installed". I also get a popup telling me that the device could run faster if I attach it to a USB 2.0 port, but I assume that's just coincidental.

I tried reinstalling several times and tried my phone in MPT mode, and with/without usb debugging enabled.

Any suggestions would be appreciated.

I ended up going back to ZV4 and then rooting and flashing CM12.1, but in the process I discovered that there seems to be a difference between using Windows in a VM and using Windows as a host, when it comes to USB devices. I ran into a very similar issue to this while trying to flash ZV4 on a Windows VM but when I tried it on a Windows host, it worked fine. My takeaway is that some of these methods probably can only be run on a Windows host (not inside a vm).

Rooting from Linux

I am trying to root my Verizon LG G3 (VS985) running 5.0.1 (VS98523C) from my laptop which is running Ubuntu 14.04. I noticed that in LG_Root.zip there are files named adb-linux and fastboot-linux which would indicate that this process is workable on linux. I was able to get through steps 4 and 5 sending the commands through the terminal with adb instead of adb.exe . I got my device into Download mode but my issue comes in steps 8 and 9 with finding the COM port and Send_Command.exe . I am able to get Send_Command to run if I use wine. I get the output:

fixme:heap:RtlSetHeapInformation (nil) 1 (nil) 0 stub
Author : blog.lvu.kr
SPECIAL COMMAND : ENTER, LEAVE

Couldn't open the port \.COM0

I tried this with all of the port names COM0 - 30 and ttyS0 - 30. I do not know the exact port as I cannot get the batch file to run on Linux, even with wine. When I removed my phone from Download mode my software status says that it is modified but I do not have root access when I checked with supersu.

Update: I believe that I have found the proper port argument (/dev/ttyACM0). When run with wine, Send_Command.exe still gives the fixme line. However, now after the special command line there is a # indicating root access but immediately following is:

wine: Call from 0x7b83b6ae to unimplemented function msvcr100.dll.get_s, aborting
wine: Unimplemented function msvcr100.dll.get_s called at address 0x7b83b6ae (thread 0009), starting debugger

and a wine program error pops up saying that Send_Command.exe has encountered a serious problem and needs to close.

Is there anyway to run the root script not through the terminal?

PreReq:

Make a nandy backup before you edit ANY system files. (You should always have a nandroid on hand.)

Now, to actually fix your borked/slow GPS!

1.) Download this here handy-dandy file -> https://www.dropbox.com/s/8uu3eeud4m9ptn9/gps.conf?dl=0

2.) Either "adb push" that file to your phone OR just download it from your phone directly.

3.) Open a file explorer (I personally use ES File Explorer)

4.) Go to wherever your downloaded gps.conf file is

5.) Copy gps.conf

6.) Go to /system/etc (you will need to grant root access)

7.) Paste AND REPLACE gps.conf

8.) Reboot

9.) Profit

This method worked on my Verizon LG G3.

Note:

This adds A-GPS support and access to the GLOSNASS system, certain devices may not be capable of taking advantage of this.
