Yes, this is optimal way!

Maybe it's safer not to do ergn,5 if next step fails region 5 will still be unchanged,
you can then get another chance.
Can someone please explain what are the contents of region 5 ?
Region 5 contains the bootloader, which is responsible for the pre-boot mode and running boot.bin and fw_all.bin.
Also it would be safer to avoid doing "ergn,5". In this particular case the device would be still alive.
@ kunix
Is this the so called "ram loader"?
Thanks,
omg, I was always afraid that all the **** I'm saying about ramloaders, bootloaders, x-loaders is misunderstood.
When I say ramloader I imply the boot.bin, and this is reasonable, because in cell phones ramloaders serve the same purpose.
So, in the pre-boot mode the bootloader (region 5) receives&executes the ramloader (region 12, virtual region, not contained in the flash chip), which in turn flashes (sometimes) the bootloder and the x-loader (so, the ramloader has inside it copies of the bootloader and the x-loader (not always)), and then receives and flashes the other regions.
I don't fully understand what the x-loader (region 43) is needed for, I suppose it executes the bootloader, so it's better to leave him intact.

Hi All,
Thanks, I make a big mistake for wrongly use the command, my bad.
Another one Nuvi 255w will be killed if I power off it.
I attempt another Nuvi 255w with correct command
first I tried only with command
xrgn,5,1:/region_5.bin
Result:
Parsing "xrgn,5,1:/region_5.bin"
Error
2nd tried, erased region 5 and write back command
ergn,5
xrgn,5,1:/region_5.bin
result:
Update.log
Parsing "ergn,5"
Success
Parsing "xrgn,5,1:/region_5.bin"
Error
Parsing "reboot"
Success
------------------------------------------------------------
Now this Unit still connect with Garmin Charger, still Power ON,
if I off it, definitely it will not power on forever,
any idea to recovery it ?

Did you have region_5.bin in the root of the memory card ?
Was the file name correct ?
It should have worked.
