There are two types of T2 capacity: 1GB and 2GB
T2 chip with 1GB capacity can control 128GB, 256GB, 512GB NAND;
2GB capacity T2 chip can control 1TB, 2TB, 4TB NAND.
So when 128GB, 256GB or 512GB NAND is upgraded to 1TB, 2TB or 4TB NAND, the 1GB T2 chip must be replaced with 2GB.
The NAND can only be removed from the Donor board , and a new NAND or mobile phone NAND cannot be used because the underlying data is different.
When removing the NAND from the Donor board , the position of the NAND cannot be wrong. For example, the NAND of the Donor board is U8600, U8700, U8800, U8900. When installing back to the motherboard, the order of NAND must also be installed in the order of U8600, U8700, U8800, U8900. Otherwise, it will report an error "9" "4013" "6"。
