This is on latest Lineage 20 on OnePlus 9 Pro, which has vbmeta as shown in the ab_ota_partition list, and previously passed the old detection with vbmeta_a. So you might need both prop and path?

How about checking ro.product.ab_ota_partitions for ,vbmeta,? Still prop-based and works unrooted.

getprop | grep vbmeta

This is on my A11 stock rom:

Infinix-X695C:/ $ getprop | grep vbmeta
[ro.boot.vbmeta.device_state]: [locked]
[vendor.boot.vbmeta.device_state]: [locked]
Infinix-X695C:/ $ su
Infinix-X695C:/ # getprop | grep vbmeta
[ro.boot.vbmeta.device_state]: [locked]
[vendor.boot.vbmeta.device_state]: [locked]
Infinix-X695C:/ #

Tried this too:

Infinix-X695C:/ $ getprop ro.product.ab_ota_partitions | grep -wq vbmeta
1|Infinix-X695C:/ $

No vbmeta traces

Hmm, well what's there now, and what will be added with my PR is still better than the broken path check from before.

@Stillhard your device definitely has a vbmeta partition? Is it an A/B device or A-only? Can you provide a full unrooted prompt getprop output for your device?

Infinix-X695C:/ $ getprop ro.build.ab_update
true
Infinix-X695C:/ $ getprop > /sdcard/Download/getprop.txt
Infinix-X695C:/ $

I wonder if first_api_level could be useful to us here. 🤔
