Question Recover data from a p11 tablet without the password

Hello hello

I have a Lenovo P11 android tablet and don't have the password anymore (the owner of that tablet died and we try to get access to the data on that device). I try to download the data to my computer but actually I'm out of ideas.

We tried:
- adb connection to the device via recovery mode (device is not being detected, seems like adb is not active in recovery mode)
- same with fastboot mode. Also "fastboot devices" doesn't show any device.
- we also found a modus called "meta mode". This seems to be something Lenovo specific, but we didn't find any further information about this mode and also failed to establish any connection to that device.

Does someone of you have any idea on how to access the data on that tablet?

Years ago I was doing a lot with android devices, adb, fastboot, custom rooms etc. But that's years ago, so maybe some things changed or I forgot some things.

We are happy about any hint that you can provide us with.

oh that's a pity. But thank you so much for your quick reply!
I thougt maybe it might be possible to sideload a custom recovery with adb access via fastboot, then connect and then try via adb.
What do you think? Not a chance or worth a try?

Greentings!
