Hello,

I followed the tutorial in this forum to flash my K800i to K810. It works ok with they SIM from the original provider, but won't accept any SIM from another provider. I tried following the tutorials in here, but for some reason it just won't work. Everytime I try to flash the vkp patch, it gives me the error "can't build loaders chain". I try to flash via USB.

I've used these files to convert the phone to K810

K810_R8BA024_FS_EUROPE_2_RED53.fbn
K810_R8BA024_MAIN_GENERIC_SM_RED53.mbn

Here's the Identify log
