RAM Memory Motherboard

Hello and thanks for posting.

If you wish to replace the memory on the logic board of the iPhone, this is nearly impossible to do.

I would take it to a certified service centre and have it fixed.

You may be able to find another logic board on a 3rd party site such as eBay tho.

I hope this helped, and I wish you the best of luck.

No, the RAM and cpu are a single integrated circuit soldered directly to the logic board. And those include the Secure Enclave system, and only that chip can work with that logic board storage ROMs.

The whole point of Secure Enclave and encryption tied to both firmware and passwords, as well as dedicated hardware, is that you cannot mix and match device components at that level.

Apple doesn't sell or distribute original spare parts to anyone, except their Stores or Authorized Service Centers.

That being said, at your own risk, you can go to a 3rd party repairer and ask them.

Regards

Giulio
