Then it must be a HWID 580 zumo 5xx not a HWID 1796 device. The big giveaway is Updater's report of Version 5.00 which is latest version for zumo with HWID of 580, the other has V3.30 as latest. With 'safe-naming' of the RGN (XXXX01000xxx), Updater.exe queries the device's HWID and refuses to do the flash if the first 4 digits don't match the device's response. Not a big deal with QuickCure3 because it's universal but it can be disastrous if an unsafe-named RGN containing full foreign firmware is flashed to incompatible hardware.

The calibration screen should appear after a set time if no flash is initiated by Updater so that shows this device is probably otherwise healthy apart from a dodgy format.

So just rename the QuickCure RGN file to "058001000500.rgn" and try again. This time hopefully you'll succeed and it'll enter mass storage mode.
