Error building tree! Work ID: eNOaBx9pRjXLFsO5ReBK

I'm not suprised seeing this, it is a weird device. It uses a allwinner h726 cpu, uname says that it's armv7.

https://www.mediafire.com/file/mhgq1zpom...O.zip/file
This zip contains the boot image (boot.fex), vendor_boot.fex and init_boot.fex (dont know what that is but seems to not do anything)

Would be cool to see this working, also thank you for the twrp builder, it's very useful.

the image i sent to the tool is boot.fex, and there is no seperate recovery partition.

Rename boot.fex to boot.img and vendor_boot.fex to vendor_boot.img.
In our tool, choose

Boot.img + Vendor_boot.img
Android 14

Leave all other fields as they are, then upload both the boot.img and vendor_boot.img (you select both at the same time)
That should build the tree succesfully
