this is a continuation to my previous questions. I damaged cpu and nand in iphone 8plus logic board while trying to replace back glass. Can cpu and nand be replaced or fixed, or do i buy a new motherboard? Thank you so much.

They cannot be replaced, that’s for sure. As for fixing them, it depends on the extent of damage, but even the “simple” reball of the CPU is quite a demanding task. The NAND may also need programming tools and skills. In any case you probably need a reputable and very skillful microsoldering tech and some testing to be able to give a definite answer to your question.
