[Q] LG G2 Stucked in Bootloop topic

Hey guys! First of all, sorry for my english, i'm from Argentina. I bought a used G2 last month, and in the box says it's a D806 (Argentina version), but in the options menu into de OS, it says it's a D802. I thought the guy who owned it before flashed a kitkat rom for D802, it worked fine. Then I installed CloudyG2 without problems, but today I asked myself if the phone was really a D802 or not. So I installed D806 KK baseband and a stock KK D806 rom through twrp, and when the phone started it didn't have any phone signal. I mean, I can't call, it says 'Service Disabled'. IMEI it's null too, but I have an efs backup.
When I try to get into twrp I realize I can't get into it. The white hard reset screen doesn't appear, I think I pressed the button combination (Vol - + Power) like 30 times. Then I tried to install twrp with the pc and debugging mode, the installation looked OK, but then the phone rebooted and the android robot animation appeared.

I'm stuck here guys, please help me out. It just stays there, I can't get into recovery mode, I only can get into download mode, but I also tried to install a kdz file with lg flashtool but at 2% of installation it crashes. An error appears and I can't do anything else.

I readed something about TOT files, but I'm really tired now, tomorrow I will keep trying, no recovery, no phone, no kdz flashing, I'm desperate.

Sorry for my english again, THANK YOU ALL! Please help me out :(
