HI s1fw ,
I downloaded this firmware. After that I made connection between the pins on one side of the chip and installed USB 2.0 (FS) ADFU Device, after that I started Mp3 player upgrade tool ver.3.86, selecting H45-3+FM-Giantplus KFM136F01-1b.bin, clicked on the button "recover firmware". In status I saw 'scanning the firmware' and after 1 minute I saw this error: Read or write device information failed! Please exit the program and check if device is connecting!
When I tested with full 3.5.37 firmware I finished upgrade process successfully but the device is not working.
