SKUID

SKUID is the value used by FIH Mobile for defining the contents and overlays for the phone, so ODMs can use the same firmware for multiple regions.

Definition

 * 1st character: Targeted OEM
 * 2nd-3rd character: Targeted Carrier
 * 4th-5th or 4th-6th (for ODMs other than FIH Mobile) character: Targeted country or regions

How to change SKUID
If you have service permission, you'll need to use following command to change SKUID.

For FIH Mobile models:

fastboot oem CustomerSKUID set [new_skuid_value]

For other ODM models:

fastboot oem repair skuid set [new_skuid_value]

But if you don't have that permission, you have to utilize either EDL or root permission to change the partition listed above.
