UFST BOX dead short

dear supporters,

my UFST box (blue case) suddenly dead during connected P5100 in DOWNLOAD mode (probably due to some short on phone side)
I felt some burned smell from box

my box is out of warranty

visualy no damaged on PCB
just IC U7 looks overheating
and all LED indicators (except RED) are lighting when box is connected to PC
PC can’t recognize my box at all

can I purchase just new PCB? (without HWK and SMARTCARD)
box details (SN, HID) I can share by PM
