Can I solve a network lock issue by changing parts?

I have two iphone 5's, the first one is a 64GB from a friend japan, works great except that it's locked to KDDI in Japan, the other is unlocked from Aus but only 16GB and extremely laggy and headphone jack and volume buttons don't work.

I want the unlocked phone with all the well working parts and ports from the other, but will this ultimately be a fruitless task by moving the same unlocked issue over to the other device??

Is this a good question?

No, but realistically it's impossible for you to swap the whole nand flash memory chip and CPU.

Which is a nightmare / almost impossible to do even for someone that does board level micro soldering repairs daily.

@ben I bought the stuff to try this. Since apparently I'm a glutton for punishment.

I'll update once I fail miserably :)


ok, well let me try and ask it another way... for the buttons ans headphone jack parts, i should be able to swap out right??

then what about performance, is that due to the logic board?? if so, can i swap that just like the jack and buttons??

the thing is, i don't actually need to solve the lock issue, i just need to take bits from the locked phone and put them into the unlocked one, all without transferring the lock issue, does that make sense?

thanks for your comments so far :)


Shouldn't be an issue to do that. The only reason I'm not committing is that I have never torn into an iPhone from Japan, so I can't say yes or no based on experience.

The lag probably comes from the board but it could be as simple as needing a restore. There are other reasons that it could be lagging but its normally just an app that is hanging in memory.
