I recently found one of my old Android devices (Orbo Jr. w/Rockchip ZX-2926D, Android 4.4.2), charged it, and turned it on. After exploring the settings, I found it had an IMEI number of
012345678912345 - definitely not unique. After some research, it seemed to belong to Android-x86 devices with tons of hints to Virtualbox and QEMU in its system file names.
Looking up the number on imei.info ends up with "Invalid number".
I would dial
*#07# on its Phone, but there is no phone. Although (about every 6 months or more), it gets malware calling itself "Phone".
It has been factory reset twice before looking at the IMEI number.
I found how to (semi) change it here, but am having an issue getting it to root (even if I wanted to use it, I couldn't). Towelroot says "your device is not supported", and KingRoot says "Rooting error".
Why does this device has an invalid IMEI?
