@master Liu I bought a Macbook from someone but it has remote management lock on it. (A1989 model). If I change the serial nuber, will it permanently remove this lock? If so where do I get the new serial number?

T56 and RT809 can't do it,because the T2 ROM input voltage is 1.8V, so only BY-T200 can do

Also this tool is unnecessary as you can use ch-341 with 1.8v adapter for about 10 dollars to do this

[@krazycoloured1]

When I saw this I thought the same. I thought a Sofi SP8-B and a 1.8v adapter with one of those test plates to rest the chip on would equal this. Are you sure? I really want to order that 1.8v adapter because I already have the Sofi

[@mbuter2553]

Changing the serial will result in not being able to activate the MacBook after resetting or updating. It will display: unable to connect to activation server. Please be careful with this. Activation needs a valid serial in the T2 ROM and matching uuid, board id etc. This can brick your device. Trust me I have tried. And it will only activate with the original serial.

friend can you help me to do the reading i already removed u4770 i have the programmer ch-341 with 1.8v adapter i don't have the pinout

[@mbuter2553]

@@Maria-do6ln hi, in my case it was the macronix mx25u3235F, however I don’t know if other types are used in other MacBooks but I think the pinout is the same in this case. Just google this chip and you’ll find the data sheet with pinout.
Be sure to make a backup of the original data :)
