How to Flash Custom ROM (TWRP & LineageOS) on SAMSUNG Galaxy A72 (A725F)

Unlocking the Bootloader

• 💡 To begin flashing a custom ROM, you must first unlock the bootloader on your Samsung Galaxy A72.
• 🔑 Ensure you are connected to Wi-Fi and enable OEM unlocking in Developer Options.
• ⚠️ Unlocking the bootloader will erase all data on your phone, so back up anything important.

Preparing Your PC and Phone

• 💻 Download and install Samsung USB drivers and Odin (version 3.14.4 recommended).
• 📁 Obtain the necessary files: TWRP custom recovery, vbmeta disabler, and the LineageOS custom ROM zip file.
• 📲 Boot your phone into Download Mode by holding specific button combinations while connecting it to your PC.

Flashing TWRP and VBMeta

• ⚡ Use Odin to flash the TWRP recovery and vbmeta disabler files to your phone.
• ⚠️ Ensure Auto Reboot is unchecked in Odin's options to prevent issues.
• 🔄 After flashing, manually boot into TWRP recovery using a specific button combination.

Installing LineageOS

• 🧹 In TWRP, perform a Format Data and an Advanced Wipe (selecting all partitions) to prepare the phone.
• 📲 Method 1 (Easy): Copy the LineageOS and GApps (MindTheGapps) zip files to your phone's internal storage and install them via TWRP.
• 💻 Method 2 (Advanced): Use ADB Sideload to transfer and install the zip files from your PC if the first method is not possible.
• 🚀 Once installation is complete, reboot your system and set up your new LineageOS environment.

Post-Installation and Stock ROM

• ✨ LineageOS offers a faster and cleaner system compared to the stock ROM.
• 💡 If you wish to revert to the stock ROM, a separate video guide is available on the channel for Samsung phones.
