Chosen Solution
Hi, My logic board is broken on the upperside, the thinner part on the side, so it does not work the hold, up an down keys, wifi Bluetooth coverage and main camera. Can i swap the necesaries chips (ic) to a another logic board in perfect status? Witch chips need swap? Also i have a empty bare logic board, can i swap all of them instead? My phone A1661 iphone 7 plus 128gb jet black. Thanks. Ricardo.
If the logic board is physically snapped in two pieces, there’s not much you can do to save it. It would be impossible to repair this. As for your other options, transferring the critical IC’s (CPU/NAND/BBCPU/EEPROM) to another board is a lot of work and the potential for catastrophic damage is quite high. Besides, if you have another working board, better to just use it. The only exception here is if data recovery is critical but IMO, the damaged logic board is probably functional enough to get the data out. Finally, bare logic boards aren’t worth much. There’s no guarantee that all of the internal traces are good (that’s probably why it’s available for sale in the first place, part of a defective batch) and even then, migrating thousands of components is not practical and probably nearly impossible to do successfully without automation.
