Hello, I just bought an EZ Flash IV 2015 version (black shell).
I've downloaded kernel 1.77 from Ezflash.cn site, copy the ezfla_up.bin to the SD card root folder and power on the console with R button pressed directly into GBA mode.
So, 'ezfla_up.bin' is detected, updating process erase...
I've been playing fallout4 all day, I went into a elevator and it kept going, never stopped, waited 5 minutes, must of been a bug. How bout you, whatcha do today?
