Can I transfer the memory of one iPhone XR to another?

The board itself holds all the data well a specific chip on there holds it… it's not so simple to just get just the data element over to another phone, it's more practical to fix the board…

In order to transfer the data would require a lot of skill havent really worked too much on the xr but I'm assuming it's similar to other iphones, u would need to transfer the eeprom, nand, baseband and cpu to another board and possibly others like wifi if u cant reprogramme the nand. That for data recovery isn't very practical ur better off saying what's wrong with the phone exactly for better advice
