I just got back to KK stock rom few minutes ago, from CM12.1 ;). [1] Installed USB Driver from the official LG site, [2] enter into Download mode and.. the first attempt, after click on Start and OK in the language window with FLash Tools, it doesn't recognize my phone. But I saw that in the end, after all the steps, it open LGMobile Support Tool program, so.. I [3] closed Flash Tools and opened LGMobile Support Tool, without disconnect the phone... I wen to "Install USB Driver" and wait until the program recognized my phone.. If there is some drivers to install the program will do for sure, in my case, wasn't necessary. After that, went [4] back to Flash Tools, started all over again.. and Voila!! :D:D

Strange thing, on windows 7 i installed the program without any problems but on windows 10 the phone isn't recognized by the flash tools :/

Anyone have success on Windows 8.1 ? I'll try tomorrow on a machine with this version of windows.

Yep.. like @GameTheory. said before.. Download LG USB Driver from their site.. Even if Flash Tools does not recognize your phone at first attempt, then open LGMobile Support Tool, and click on "Install USB Driver", it will recognize your phone. After that, go ahead with Flash Tools again ;)

Win 10 - d858hk - upgrade to 5.0.1 successfully

Hy, the application LG Flash Tool 2014 worked well, did all the steps to upgrade my LG G3, only after I passed out the second screen I encountered a small problem, the words did not appear on the application, only "????" . I think is do to the language that wasn't supported by my win 10. I wait for it to finish, and then force-close the app. Thank you!

FOR ALL THOSE WHO HAVE CONNECTION ERROR

I had the same problem and I was at my wits end what exactly to do. I even unrooted my device. Flashed an older firmware and then flashed the same firmware. All worked fine.

Actually I found out that I could flash 24A while couldnot flash 39A for my device.

Then I checked the MD5 checksum and it DIDNOT match for 39A and that's why it was not being flashed.

So next time check it and try again.

Here is the link for free md5 checker

Also, make sure you have all the drivers and you put your phone into download mode (power off completely. Then while holding volume + button, plug in via usb).

Download KDZ file via simple FIREFOX if it is a direct KDZ file. Else you may use softwares like IDM etc for ZIP / 7z formats. What I found interesting was that every time i did with IDM, it would give me error when it was downloaded around 70-90% and the reason for error was that data doesnot match the previous data received.


Sometimes you can not flash fromm one firmware to another directly. Like you can not jump from 24A to directly 39A. You will need 27A boot for that. Just if makes sense to you

Good Luck

I had a p769, with same "no connection to server" with LG flash tool 2014.
I left that window open and started searching online. After abt 10 mins, i heard some tmobile jingle. The phone restarted!!!
Those who get that error, try leaving like that for 10min or so. :laugh::good:

My phone got stuck in download mode after the update failed and froze at 12% with this app with a little "rooted" warning in red in the box

...used the latest LG support Tool which downloaded the latest firmware and updated the phone with a full wipe

    CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.
