I don't trust the shop with my data.but if you dont say the other party also wont know right ?
Btw some shop charge a fee to transfer data from old hp motherboard to your new one if the old one screen spoilt . $40 for android. Apple not sure .
On my old Note4, I managed to desolder the flash chip and transfer to a microsd emmc board. After that I was able to access the data like in a thumbdrive.
Once data all copied out, formatted the chip and used it as a flash drive for mp3 in car.
