Hi all：

I'm thinking of adapting ArrowOS for my device. Its model number is Lenovo L71091.

and I currently don't find any information about it on github. How can I make device and vendor myself.

The Stock ROM cannot be uploaded because it is too large.

Attached is an image of the boot recvoery dtbo for this device.

Is it possible to extract to “device tree” and “vendor tree” by this how can I do it.

Forgive my english

Any help

Thanks

Do you mind upload the stock rom you have, so I can have a copy?

Just want to have a backup to restore, I'm also looking at trying to do a custom ROM and also dealing with some bugs.

Thanks again.
