IPhone 7 and 8 eeprom ic


hi

on iPhone 6 and 6s we had eeprom ic so if we swap CPU and NAND to different motherboard we still need to swap eeprom ic so the device can boot without restoring the device and loosing the data. but on iphone 7 and 8 it seems there is no logic eeprom anymore only baseband eeprom is there? so if we only swap cpu and nand flash to another board the device will boot without restoring?

If you change only the CPU and NAND, then the device will not boot, you need more ARB to download, and in order for the data to remain, then NFC, since a strip will go with someone else's NFC with an attempt to restore data. Sorry my bad eng.
