That is not a GT Media Finder Pro2.
Is that the chip programing adaptor?

This is the adapter for charging the GT Media Finder Pro2 after 1 hour of use. I had not used it before because the GT Media Finder Pro2 battery arrived charged.

At least with it being C type USB, you can use another charger.

i found my V8 Finder Pro (1) charged best on a 12v USB adaptor in the car.
Using 5v USB type C and the finder Pro does not fully charge and go from red charge LED to Blue/green.

Good luck. not a good start.

Watch if you fully discharge the finder.
See my battery fire here.

The Finder V8 Pro uses a 25Q64 memory chip. This is an EEPROM flash memory chip with a capacity of 64 Mbit, which is equivalent to 8 MB.

I had to unsolder the chip to get a better picture of it. This is a UC25HD40. I don't think this is 8MB (64Mbit). The programmer keeps showing me that the ID is B3 60 13. I tried programming it with EZP2019+ and with CH341A, but without success. I wonder where the program is stored. I don't see any other chip except 24C16.

This flash memory is 4MB

This flash memory is 4MB

OK. Then tell me which part of an 8MB file should be written to this chip.

Lining can give you that information.
