How to Install Custom Recovery (TWRP) on Samsung Galaxy A72: Step-by-Step Guide

Understanding Custom Recovery

• 💡 A custom recovery like TWRP offers more options than the standard recovery mode, including ADB sideload, installing zip files for custom ROMs, and advanced wiping capabilities.
• 🚀 Custom ROMs are unofficial versions of the phone's system, allowing for different user experiences and potentially newer software versions.

Preparing Your Samsung Galaxy A72

• ⚠️ Before proceeding, back up your phone's data and sign out of your Google account to avoid potential issues.
• 📌 Verify your phone's model name; this guide specifically covers the A725F, and different models will require different files.
• ⚙️ Enable Developer Options by tapping the build number seven times in 'About phone' > 'Software information'.
• 🔓 Within Developer Options, enable OEM unlocking and ensure it's grayed out with 'Bootloader already unlocked' if you've previously unlocked it.

Unlocking the Bootloader

• 🔌 Power off your phone, then boot into download mode by holding Volume Up + Volume Down and connecting the USB cable to your PC.
• ▶️ When prompted, press Volume Up to confirm unlocking the bootloader. The phone will restart, which may take some time.

Setting Up PC Tools and Files

• 💻 Download and install Samsung USB drivers and Odin (version 3.14.4 is recommended) from hardreset.info or similar sources.
• 🗃️ Extract the downloaded Odin executable and the custom recovery files (TWRP and vbmeta disabler) for your specific model.
• 🔄 After installing drivers, restart your computer to ensure they are properly recognized.

Flashing Custom Recovery with Odin

• 📲 Boot your phone into Download Mode again (Power + Volume Down, then connect USB, then Volume Up).
• 📂 In Odin, click AP and select the TWRP file, then click CP (or the relevant slot for vbmeta) and select the vbmeta disabler file.
• ❌ In Odin's 'Options' tab, unselect 'Auto Reboot' and any other pre-selected options.
• ▶️ Click Start in Odin to flash the recovery. If it fails, try again or ensure the phone is properly recognized.

Booting into TWRP and Next Steps

• 🔄 After flashing, disconnect the phone. To boot directly into recovery, press and hold Power + Volume Down until the screen turns off, then immediately switch to holding Power + Volume Up until the TWRP recovery screen appears.
• 🛠️ Once in TWRP, you can perform actions like ADB sideload, create backups, or install zip files for custom ROMs.
