don't post your imei number here my friend.
are you flashing a tot or a kdz file? what OS are you using? did you install the drivers?
did you do a factory reset after flashing?

Remove your imei, someone could report it as "stolen" and you won't be able to use your phone again.
Your imei is private.

Download mode doesnt work.

Hi guys, im having a big problem over here.I have European d855 g3, 32gb version.When i turn it on phone freezes on lg logo and restarts.I thought it is a soft brick so i tried everything to flash it to stock and fix it with all flash tools , and i had a errror like "MODEL INFORMATION CHECK FAIL"" that is with LG flash tool ,When i try to get into download mode phone stays there a while and just restarts, stock recovery is stuck on logo too.So i thought it was battery and i bought new one.Problem is still here.Then i tried on my friends battery too.Nothing helps.
