How to Install LineageOS Android 16 Custom ROM on Samsung Galaxy S10+

Unlocking the Bootloader and Prerequisites

• ✅ Uncheck all options in Odin's Options tab except for Auto Reboot, then click Start to flash TWRP.

Installing LineageOS and Google Apps

• 🔄 After flashing TWRP, boot into recovery mode by holding Volume Down + Power, then quickly switching to Volume Up + Bixby when the screen turns off.
• 🔒 In TWRP, format data by typing 'yes' and then run the multi-disabler script.
• 💻 Copy the LineageOS ROM and MindTheGaps (Google Apps) files to the phone's internal storage.
