If You tried this on Win8.1, next step is JTAG.

But then its always stop on 60% and nothing changed

I experienced it too,
It was working perfectly,
but now its always says the phone is disconnected.
Maybe this is drivers related?
But im using the drivers on the first page already :(

dude can you help me... i am always stuck at SOFTWARE UPGRADE during download mode..always at 4%.. ok i am using an old one.. LG OPTIMUS G (L-01E JAPAN)

is the cause of this issue the driver?

Hi,it seems there are two 4%!
Mine had stucked in 4% too(approximately 1 min) in the 1st step!
But then I guess the 2nd step started & the tool started flashing from 0 to 100 smoothly!
Im not sure really But I guess you are not stucking in the flashng step but before the flashing starts.
While Im not sure, I guess you might need to try with another pc & also move the kdz into the flashtool folder
You better try other vesions of driver.
You might want to make sure kdz is not currupted(try another one)
actually there are many things to do!

i did try on another laptop now..

ok it went to 4% also but clicking retry..it went to 100%..thought i was about to smile..but instead of the welcome screen wherein we will choose the language..it just showed there something like a problem that i need to do factory reset


tsk tsk tsk....dang! nothing happens on the factory reset button

hoping an issue with kdz

now i use official app..and it detected the phone (i hope) and now downloading latest update as we speek..hoping this time it will be ok


anyway..on my G3... this TOOL is simply amazing.... tsk tsk too bad for the old L-01E of mine :(

I have been using this tool already few times and it works like a charm. Thanks OP ! :)

P.S - If there happens to popup some error during installation, just don't click on anything and leave it, it will complete it!

Hey. A few days ago I flashed KDZ '' V30d-VDF-COM ', the battery life on it is terrible to me. I want to flash '' V30b NEU / EUROPE OPEN ''. Can I do it without losing any data in my phone, and will it boot normally if i do it? I'm on D802

    Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
    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.
