☆ Trick & Tips No.2​

Changes "RO to RW Script" or Uses "vndklite variant"

=》 which the way is the best for you ?

》》 vndklite had normal status to "Read only System Partition" .Before we uses it to write status by

mount -o rw, remount /system

Then modify or edit any in /system sub-partition.

And How about free spaces ?

2- Use set of fastbootD command flash GSI ( lineage-20.0-20230324-UNOFFICIAL-arm64_bvN.img ) over Stock ROM above.

3- I had used "RO to RW Script" make " New Super.img" changed RO of GSI-lineage-20.0-20230324-UNOFFICIAL-arm64_bvN to RW and plus 300 MB free spaces to this system sub-partition.

☆ Trick & Tips No.3​

Why Rooted debugging ? and Howto.

Environment: without Root / Magisk.
