You do actually need to be sure which HWID you have, MTK chip [1104] or non-MTK [0972]. However, if you try to flash the wrong .rgn, you would normally get this message from updater.exe:

I take it that you don't have a files backup to check which hwid you have on GarminDevice.xml. Are you sure that you kept your finger firmly in the LH top corner at least until the word 'Loader' appeared on the screen? Moving your finger even slightly or reducing the pressure early in the flashing process can cause it to fail but it's so long since i've had that happen that i can't remember the message. Keep trying, and if you get the same error try to make a screenshot and post it here or write down the exact message. Also re-make the cure rgn from scratch just in case something is corrupt in your first attempt. You could try a cure rgn made from the other fw but i don't think that's the problem.
It's possible Garmin could tell you what chip you have from the unit's S/No., but that may take some time.
