hi bpb,
I tested the command, it succeed erased the region 5 and also succeed to write the Region 5, see below.

Report on one Nuvi 255W was killed.

I did back up 2 Nuvi 255W all the region, which same HWID 827.
attempt to erase the region 5 and write back the region 5 which from other Nuvi 255w,
command as below:
ergn,5
rrgn,5,1:/region_5.bin
reboot

update.log
Parsing "ergn,5"
Success
Parsing "rrgn,5,1:/region_5.bin"
Success
Parsing "reboot"
Success

Nothing change, but once I switched off the Nuvi, it's dead, no power on, even connect with Garmin charger or USB cable connect to PC, still no Power on,
May be can announce that "it's Dead", Sorry for hear that.

If you want to WRITE region 5 from other Nuvi you must use xrgn instead of rrgn:
ergn,5
xrgn,5,1:/region_5.bin
reboot
BTW ergn,5 it's not obligatory. By xrgn,5,1:/region_5.bin you will overwrite the region 5.
