“NAND replacement on an iPhone 11 involves removing the original embedded NAND flash memory chip from the logic board and installing a new one. The process requires reading the original boot data (including firmware, serial number, IMEI, etc.), transferring it to the new chip via a NAND programmer, and then re-soldering it precisely on the board using micro-soldering techniques. Proper thermal control, fluxing, cleaning of contact pads, and verification of boot and system integrity are essential. If the boot data is not migrated correctly, the device may fail to activate or boot.”
