I just received my VIM3L HTPC Kit and I am excited to start exploring. I have already burned the latest CoreElec Stable version to a MicroSD card and it boots perfectly. The version on the EMMC also boots but it is an older version.
I have burned Krescue to another MicroSD and booted into it to take a look. First thing I did is write the current EMMC contents to the MicroSD card. If I decide to install a different image for example Android Pie once I have finished experimenting can I write the image I backed up on the MicroSD back to the EMMC thus restoring the VIM3L to the state it is currently in now?
Is there any limitations I should be aware of? I saw in another post that someone had trouble booting back into Krescue after using Android TV. I am not sure however if he used the image available within Krescue.
My apologies, I have not done this myself and so cannot offer advice on it.
It maybe that the Android TV image used is a custom ROM and uses a different version of the bootloader and may interfere with booting from card. Just speculation.
Not likely you will hard brick any of the Khadas SBCs, they are very tolerant.
@Richdem Is there any way you can share with me the original EMMC contents that you write to your MicroSD card? I also just bought a VIM3L but I ruined it before I backup the original content.
If you download & burn the Krescue image you can create a rescue MicroSD Card. You can then boot into Krescue and flash any of the available images to your EMMC. I tried a few different ROMS over the weekend and it works perfectly. I ended up with the latest CoreElec installed to the EMMC as my VIM3L is going to be used as an HTPC.
