This will hopefully be useful for someone. I upgraded my CV2 to the newest Nextor Beta 2 and ran in to problems.
Issue 1: after erasing the CV2, I forgot to initialize the CV2. Trying to write the bootblock, I got an error "file not found" and beyond that point, the CV2 was dead, because C2MAN hang. Reboot jumped straight to MSX-Basic because no bootblock.

I created a MSX-DOS 1 bootfloppy with C2MAN, all the required firmware files and booted from that floppy. C2MAN started and I could initialise the CV2. Next I reflashed the boot,IDE and FMPAC parts. CV2 came back to life after reset, but Nextor would find the SD card as master, but jumped straight to MSX-Basic. I remembered that I read that partitions had to be marked active for Nextor to work. So from Basic _FDISK and mark partitions active. My Mac shows 4 partitions on my SD card, and the order is more or less random, so I copied nextor.sys and command2.com to each partition and through trial and error (mark partition 1 active, boot, are the files there?), I discovered that my third partition is the one that contains all my data.

So I short: read the manual and don't forget the initialise step. Otherwise: have a MSX-DOS1 boot disk with C2MAN and required files to save the day.

I don't think you need to erase and initialize just for changing the Nextor though. You should be able just to flash one Nextor rom (renamed) and that's all

Never tried it before, but since there also is a new bootblock, I reflashed all.

It is indeed not needed to start over, just reflash individual firmware is possible with c2man (to be honest, I also reflashed all when the boot block update was delivered)
