LG G2 D8023D stuck on LG logo !. Goes into Download Mode but both KDZ and TOT failed to install.

Hi Guys,

I have my LG G2 D8023D handset which restarted all of sudden and is not stuck on LG G2. My phone is already rooted and I've tried flashing with KDZ file as well as TOT file but they failed to install. Also, in my device manager I noticed that there is some problem with the drivers, I tried installing them too but no luck.

Can you guys please help?
Best Regards,

 

Hi Leo,

Yes, I'm using LG Flash tool to flash these files. Now, whenever I boot my phone I shows a green android sleeping with red exclamation and restart automatically after some time.
When I try to Flash KDZ file, the tool stucks at 4% and then asks to retry
When I try to Flash TOT file, the tool shows an error message "LAF Memory Size" error.

Can you please advice?
Thanks,
