Testing

The tablet builds are new and nobody has booted them on a real tablet yet. If you own one and want to help, join the Discord and ask for the test image.

Device Chip Status Notes
Lenovo Legion Y700 Gen 3 (TB321FU) 8 Gen 3 Testing BOE and CSOT screens both supported
Lenovo Legion Y700 Gen 4 (TB322FC) 8 Elite Testing Chinese model only. The TB323FU is a different chip and isn't supported

How It's Different

The tablets don't use the ROCKNIX ABL and have no microSD slot, so they work a bit differently from the handhelds:

  • The image goes on a USB drive instead of a microSD card.
  • You start it from a PC with fastboot boot, using the boot image in the drive's tablet folder. This needs an unlocked bootloader.
  • From there you install it to internal storage. This replaces Android's user data, and Android's boot image is saved so you can go back.
  • There are no built-in controls, so use touch or a Bluetooth or USB controller.

The Gen 4 copies the firmware it needs from the tablet's own Android, so don't wipe Android before the first boot.

Which Gen 3 Screen Do I Have?

The Legion Y700 Gen 3 comes with a BOE or a CSOT screen. The boot menu has an entry for each, BOE first. If you get a black screen, restart and pick the other one. In Android you can check with getprop ro.vendor.display.paneltype over ADB, 1 means BOE.

USB Drive Not Showing Up?

Both tablets switch one USB controller between their two ports. If the drive isn't seen, try the other port.
