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. I think it is not a hard brick because it is still giving signals of life. Sorry for my bad English, but i desperately need help! :crying: :crying:
