[MeMO Pad 7 General] lambdadroid:
Thanks a lot! Do most of the consumer tablets use the same GUIDs? Here are the GUIDs used by the ME176C (as far as I could figure out, I used blkid) in case you need them:

/dev/mmcblk0: PTUUID="2174eed4-de7b-ce63-a050-23ee9834bad2" PTTYPE="gpt"
/dev/mmcblk0p1: PARTLABEL="reserved" PARTUUID="80868086-8086-8086-8086-fffffffffff0"
/dev/mmcblk0p2: PARTLABEL="metadata" PARTUUID="80868086-8086-8086-8086-000000000001"
/dev/mmcblk0p3: LABEL="ESP" UUID="FDF8-379F" TYPE="vfat" PARTLABEL="ESP" PARTUUID="c12a7328-f81f-11d2-ba4b-00a0c93ec93b"
/dev/mmcblk0p4: PARTLABEL="boot" PARTUUID="80868086-8086-8086-8086-000000000100"
/dev/mmcblk0p5: PARTLABEL="recovery" PARTUUID="80868086-8086-8086-8086-000000000101"
/dev/mmcblk0p6: PARTLABEL="fastboot" PARTUUID="80868086-8086-8086-8086-000000000102"
/dev/mmcblk0p7: PARTLABEL="reserved_1" PARTUUID="80868086-8086-8086-8086-0000000000ff"

gdisk output: (for some reason the method above didn't show all partitions)
