Windows 10
Gecho App v0.61b
Clicking the 'check for updates' option then checking for available firmware returns a message to the effect that current firmware is 0.223 and that an update to v5.0 is available.
Update process appears to run [clearing memory and writing several sectors of data, handshake LED activity as previously seen]
After 'update' checking for available updates shows that Gecho still has firmware v0.223 installed.
Repeating process appears to give identical result.
Channel 112233 reports 223
Or so it appears here.
If I can give any further info please let me know, thanks!
