Get MLB Serial from serial or imei?

You do not need the MLB number for the phone to activate. You just need the Serial number, Blue tooth and Wi-Fi Address. I have never put an MLB number into the JC programmer. If I copy a nand it is there but when I manually program it I only input those three plus edit the region colour etc. The MLB number probably gets written when activated.

Before I got a NAND programmer I use to buy NANDS from aliexpress I would only supply them with the serial number, Wi-Fi and Bluetooth Address and they activated just fine.
