jdFlasher with K770i (CID 53) problem

I'm trying to install a flash menu into my K770i mobile.
When I try to connect via FAR, it gives the following error.
I'm using FAR version Far Manager + JDFlasher T6 + CID52 Patching + CID53

Can anyone figure out what happened and what to do?

you should select "db2020" and not qa2020 and make sure that you have reinsert your battery and follow the complete procedure for customization

after this, I also tried db2020, but had no luck :(

try a fully charged battery, your problem might be with the battery
