Question update firmware PocketGo2 V2

[retrogamerfan]

I need a tutorial to update the Rogue firmware on New Pocketgo2 v2, I saved the update file on card 2, inserted it in the device, opened the file but it didn't update

in info appears the 2020 firmware

I don't know too much about Rogue, let alone Rogue on the Pocket Go, but if you haven't updated your firmware in a year, it'd probably be best just to do a full reinstall. There's probably been some big underlying change that means the update file won't work as expected.

the file only available for update does not need re-installation because the rom is unique but I don't know how to proceed with update
