Multi boot image EMMC- Android-ok Ubuntu-ok EXTSD- LibreELEC OS-false

Flash Vim_LibreELEC_V170116 to SD card by using Win32DiskImager.
On Android we offer the possibility to reboot LibreELEC but after the reboot boot back to Android
Please tell me what I did wrong thank you

Hi, Reader5:
Actually, nothing you did wrong to switch from Android to LibreELEC, it’s our release LE ROM still doesn’t support the triboot yet.

Before our new LE ROM updating, you can take a try with Balbes150’s ROMs, he did lot of great ROMs on Khadas VIM, you can check the topic for further details.

1.Android on emmc
-flash via USB_Burning_Tool_v2.0.8
android (Vim_Nougat_170321.7z) to emmc

2.Libreelec (from balbes150) on (USB1 or MicroSD1)
-flash whit linux tool( image (LibreELEC-S905.aarch64-8.0.2.img.xz) delete dtb.img whit multiboot activation

3.Ubuntu (from balbes150) on (USB2 or MicroSD2)
-flash whit linux tool( image (Armbian_5.27_S9xxx_Debian_jessie_3.14.29_xfce_20170323.img.xz)

dualboot work Android(EMMC)/Libreelec (USB1/MicroSD1) or Android(EMMC)/Ubuntu(USB2/MicroSd2)

So I am satisfied it’s almost like a triple boot

Hi, I have bought a used standard vim that has no operating system installed. I would like to install Android + Openelec + Ubuntu + Buildroot Multi - OS. My Windows PC does not recognize the vim when connected by usb or usb-c, so I will use a micro sd card. Any help would be greatly appeciated.

It’s off topic here, so I will move to a better place.

If you want to install multi OS, the only limitation is the VIM devices don’t have enough storage room, normally, Android will need 6GB+ room, and Ubuntu with desktop also need 4GB+ room, and OpenELEC/LibreELEC require 2GB+ …

Of course, you can try install some O/S on eMMC, and others on uSD card, you can looking around the forums for instructions.

We’ve release Android + Ubuntu DualOS for VIM Pro, you can refer Firmware Pages for the details.
