[G2 Android Development] Sohnay:
after disconnect inter same problem there.[IMG="problm"]http://file:///C:/Users/st/Desktop/Capture.PNG[/IMG]
[G2 Android Development] Bangash737:
Actually it is due to different kernals / files that custom roms uses which leads to such error. This server connection error means that Flashtool unable to recognize your phone model.

Solution is simple= if your TWRP rec is working, Find Factory Stock rom (i prefer Lollipop) in ZIP form in accordance with your mobile model, flash it and then try Flashtools.
[G2 Android Development] Sohnay:
Sir I am alrady on stock rom. 4.4.2 KK. D858HK. lg g3.

I mean fresh stock zip covertd out of kdz file of a specific model like Stock zip D858HK which contains no recovery nor Superuser.
[G2 Android Development] Sohnay:

[G2 Android Development] Sohnay:
have u solved ur problem i have same problem on my lg g3 d858hk. plz help me if u have solved.
[G2 Android Development] Lucas_Skyline:
Yes, I solved some months ago. I remember that was a problem with the LG driver. Try to uninstall everything you have from LG in your PC and installing again. When you plug your phone into the PC (in download mode), check the status of the driver in the Windows Device Manager, under the Portable Devices option. If there is an yellow exclamation dot, it wont work.

I made this process several times before it worked.
[G2 Android Development] jean luc Rio:

Thanks, your tool just saved my ass my G3 was stuck in fatsboot mode, and the other LGFlashtool didn't work for some reason. This tool was my last hope.

I have D852 LGG3, although the flash tool gave me a connection error it still ran all the way through in the background.

Thanks a million

I had the %2 error issue after flashing Cloudyg2 3.1. When I tried to go back to stock flash tool stopped at %2 and no flashing was possible. Thanks God I had TWRP. My solution was to flash the flashable zip stock rom I downloaded from the below link. After installation I was able to use KDZ method again with no error.

Uhh well, I bricked my phone trying to install some mod and well, I used the LG Mobile Support Tool once and I restored my phone but now I can't.

I can go to download mode as well as TWRP, but the LG Mobile Support stuck at 2% and the phone doesn't show COM and a number, it's just there at download mode. If I install CloudyG ROM the LG logo appears but just 1 second, then a black screen and I can't do more than turn off the phone and try to enter again to TWRP or Download mode. Can, please, anyone give me a solution? Thank you.

Hey, hoping someone can help. I have an LG L90(D415) and its stuck on the LG screen. I can boot into download mode(firmware update) and I have the latest drivers and kdz file. But whenever I use LG Flash Tool is gets stuck on 2% then says “upgrade stopped due to an error”. I went to device manager and the “LGE Android MTP Device” has a yellow exclamation point next to it, not sure if that’s the issue or not. I’ve tried this on Windows 7 and 8.1 computers, same results.

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.

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

http://winmd5.com/

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

[G2 Android Development] Langz:
So you first flashed stock lp trough recovery and then the kdz with the flash tool? Or just straight ahead LP kdz?

If so you first flashed stock lp trough recovery, what zip did u used (because I was partially on that way but the original LP rom without losing recovery did not work out)..

Update: It finally worked out! I think part of the problem was a buggy usb port on my laptop. Procedure: first flashed stock LP through recovery with a .zip file, then flashtool with original kdz.
