:laugh: Sorry I misunderstood your question :o

The answer your looking for is "sgdisk" but be very careful with this tool it can fry you partitions if you do not know or understand the cmd's

Follow my example below ( sgdisk --print /dev/block/mmcblk0 ) from adb shell

F3111:/ # sgdisk --print /dev/block/mmcblk0
Disk /dev/block/mmcblk0: 30535680 sectors, 14.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): 98101B32-BBE2-4BF2-A06E-2BB33D000C20
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 30535646
Partitions will be aligned on 512-sector boundaries
Total free space is 13245 sectors (6.5 MiB)
