[Android Q&A, Help & Troubleshooting] skolmin:
Hey everyone,

I got a Lenovo tablet from my friend's company. The employer who has set it up left the company. Now they can't do anything with the tablet.

How can I completely reset the device and delete all passwords?

------

I was able to boot into fastboot, but couldn't do anything there:

./fastboot devices

HA11GFCA fastboot

./fastboot oem unlock-go

FAILED (remote: 'oem unlock is not allowed')

fastboot: error: Command failed

./fastboot flashing unlock

FAILED (remote: 'oem unlock is not allowed')

fastboot: error: Command failed

------

I was also able to boot into Android Recovery. I successfully wiped the cache partition and did wipe data/factory reset. The tablet keeps asking for the password if I boot it.

I tried adb sideload with https://mirrors.lolinet.com/firmware/lenovo/Yoga_Smart_Tab/YT-X705F/ but got the instant error: adbd status 1 installation aborted.

How can reset the tablet to set it up from scratch? I don't care about any data. Just want to be able to use the tablet. I have no access to the tablet, so I won't be able to toggle the unlock oem button in settings or anything like this...
