Windows OS cannot do all for VCM 2

I’d have to answer that not everything can be done from Windows operation system.

For example I can’t modify and rebuild initrd, rootfs, or the kernel from windows.
Sure, I can use winimage (or the like) to read files but that’s not everything and honestly it’s more effort to achieve even that level of access on windows than using it natively on Linux.

I am very comfortable with Linux having done minor development for a distro. I don’t have a automotive background, but instead an IT background. I realize that not everyone has Linux experience and that’s fine. But it’s a highly effective and versatile tool platform.

FYI, I was able to restore my VCM2. If you find yourself in the same situation:

1 Download and use ExtraPuTTY (Use Ymodem mode for transfers)

2 Download firmware from https://mega.nz/#!utIHlA7b!0EA9jWLptCtQx1-Rlxh5KwcytGsxsS1aGqpZjZKBVG0 (Big thanks to baner)

3 Connect to the serial bootloader

* Be careful to not mess with the fsboot/mtd0 & boot/mtd1 partitions. If you do you’ll need to use a flash programmer or JTAG to recover your VCM2.

If there is any interest, I expect to write a slightly modified version of the most recent firmware that doesn’t block WiFi, always boots to testmode, and has some additional utilities in the web interface (change VCM type, spoof version, web based firmware update. I’m open to suggestions).

@mattydr67 & baner
I’ll be glad to as soon as I have some info to share.
