Chosen Solution

Im looking at changing the following chips between two matching iPhone 6s.CPU chip, Qualcomm baseband ic, nand memory chip, my question is after getting them both finished will i need programming tools? For each chip? When i first researched this it looks like you can just switch them and turn them on. Now I’m being told differently. Also I was just told I’m missing a piece. Yes this is for refurb of phones with iCloud activation lock. Clean imei not stolen

That’s an awful lot of work to “remove” the iCloud lock. If you have a perfectly good logic board that is not locked, why not just put the whole logic board in the good housing? If it’s just a memory capacity issue, you can upgrade just the NAND. Don’t be fooled by the apparent ease with which the tech does the swap in the linked video…these guys are insanely skilled and they have done this hundreds of times to be that good. If you have never done anything similar, you will not succeed on your first attempt.

See this video. Hope it helps. https://www.youtube.com/watch?v=G-tbLa7e
