LG G4c H525N locked with custom app - LG G4c Questions & Answers

I've came across a LG G4c which has some custom restaurant software in it. Nothing of android is visible, no back button, no status bar. If I hard-reset the device, the same application opens. I can't connect to the device using adb, can't install any software. LG UP doesn't recognize it, I installed the manufacturer's USB driver.
Can you suggest any way to install ROM to this phone?
Thanks, Vilo

Drivers won't install F320S

I have tried to connect my brand new (bought tonight) LG G2 F320S to my computer to update the OS. (kitkad is now available here in SK)
It won't automatically install the drivers. I have downloaded new drivers at the LG site. I have installed PC suite. I have gone to the device manager and tried to repair or update the drivers there. Nothing is working and it won't connect to the computer. Any ideas? Not looking like a great choice so far. (never had problems with my samsung galaxy phone) Thanks.
no ideas? I just updated the pc suite on the phone itself. Still won't work.

[Q] Can't get LG G2 back to stock / unrooted

Creating a troubleshooting thread to see if might be able to get some help on a big problem I'm having with my LG G2...
I'm trying to restore my VZ LG G2 to stock so that it can be returned (audio input is malfunctioning). I am currently running TWRP + CM 11 Nightlies on it.
When I enter download mode, I see the screen "Firmware Update" and it says "B99" and "Rooted" at the bottom.
When I use the R&D Test Tool + LGMobile Support Tool to try to restore to VS98011A_01.kdz, the software update runs on my computer as if it is pushing the update to the phone, but the phone itself shows no actual status change. It just sits there with 0% on the status bar.
When it finishes on my computer it says (on my computer) that the software update was successful. Unfortunately my phone boots into CM just like it normally does with all my apps and data there.
Based on some suggestions I have seen, I have tried manually changing to COM 41 and disabling the device as a modem in device manager -- does not make a difference.
I have no idea why no actual change is happening on the phone. Any suggestions?
Man, this is brutal. I thought that maybe the issue was that I was using the 3.10 LG United drivers instead of the 3.8 drivers, so I uninstalled 3.10 and installed 3.8.
Unfortunately now the LG G2 is recognized when it is in normal mode (running CM 11.0) but Windows shows "No drivers found" when I put it in download mode:
USB Composite Device: Ready to Use
CDC Serial: No drive found
CDC ECM: No driver found
LGE Android Phone: No driver found
Network Controller: No driver found
The last four all show up under "Other devices" in device manager with an exclamation.
Previously I was at least able to see the LG Android VZW etc. etc. under COM/Ports with 3.10 drivers installed.
I am burning so much time trying to figure this out. Mayday, mayday!
For anyone that may come across this thread in the future, I want to share what ultimately worked.
I followed the TOT method instructions in this thread: http://forum.xda-developers.com/showthread.php?t=2448960
It was just as easy as the KDZ method, but actually worked! Here are the two things that seemed to make a difference:
1. I installed the _Verizon_ LG drivers referenced in that thread
2. I manually changed to COM41
Following all instructions in that thread everything worked like a charm.

LG G2 bricked, can't fix

Hi all,
I've broken my LG G2. I made an edit to build.prop and the phone stopped working. It will display the LG logo but then the screen goes black and the LED slowly flashes green/blue. I was running stock Rogers firmware, rooted, with a stock recovery.
I've performed a factory reset. Didn't fix anything.
I have tried to connect via ADB and fastboot but the phone isn't listed as a device.
I've tried using the LG Update program. The phone connects and is recognized but fails when reaching 4%.
I've used the LG Flash Tool 2014 but that fails at 2%.
When the phone is plugged into my computers, device manager shows it as: LGE AndroidNET USB Port (Com3) and LGE AndroidNET USB Modem. There is nothing else listed. I've tried installing all the recommended drivers; there is no change.
I have no idea what to do next. I'm hoping someone here can help.

Have you tried this driver? http://www.koushikdutta.com/post/universal-adb-driver As the page states, even when the manufacture offer their own drivers, ADB still won't recognize your phone as a device, sometimes. I had a similar experience and after installing this particular driver from Koush it recognized it. Hope it helps.

[Q] LG L5 E610V Bootloop

Hi Guys,
When updated my LG L5 E610v with LG Mobile support tool, it stucks in 'Download is in progress. Don not disconnect cable.
Tried a lot to fix this problem, no results.
I figured out that using adb, fastboot, PDAnet, LG suite, LG mobile support tool, kdz updater, a lot of different usb cables, button combinations, shake the phone, etc, my pc (and all software I used to connect) do not recognice my phone properly or not. For example: using adb, i get: device not found, etc.
I installed the right lg usb driver properly and see on device manager 'Modem' and 'usb device' installed. Seems to me, no proble at all !!!
Who wants to help me to figured out this problem ??? To say this, I am a noob with this problem.
Thx in advanced,

LG G2 not recognized by PC after unbricking

Hello, I recently rooted my LG G2 d802 phone because it got a little old and the Lollipop update was overheating the phone while multi-tasking.
Unfortunately, i bricked it by mistake. Afterwards, I managed to fix it using SRKTool and installed the official and latest Blisspop ROM. The phone is working great except for one thing, it is not recognized by any PC anymore. The LGE Modem Driver and LGE Mobile USB Port got installed, but I can't see the device in My Computer, nor the LG support or LG PC Suite or LG Bridge apps can.
I installed every driver for d802, even adb or android universal ones. No luck though.
Not even the download mode is recognized by the PC anymmore.
What can I do?
Thank you very much for your time!
