🔧 What’s New in 3.7.0-9-0

• Updated AOSP base – Synced with the latest Android security patches and recovery frameworks.
• Improved decryption support – Better handling for Android 12 and 13 metadata encryption (FBE + FDE where applicable).
• Fastboot enhancements – More reliable flashing and partition management for devices that rely on fastbootd.
• UI and touch improvements – Smoother rendering and better touch responsiveness, especially on newer display panels.
• Backup/restore fixes – Resolved edge cases where certain partition types (like super, vendor_boot, dtbo) failed to restore correctly.
• Language updates – Various translation improvements across multiple languages.

Key Changes & Fixes

1. Decryption Improvements

• Fixed: Broken decryption for devices using metadata encryption (FBE – File-Based Encryption) on certain kernels.
• Fixed: Decryption failures on some Samsung Exynos and MediaTek devices after Android 13 updates.
• Improved: Support for larger encryption overhead introduced in Android 12+.

2. Backup & Restore

• Fixed: A bug where backing up the super partition on dynamic partitions devices would fail or produce corrupted images.
• Fixed: Restoring backups to devices with different partition sizes (resize2fs issues).
• Improved: Incremental backup speed when using external USB drives.

3. A/B & Seamless Updates

• Fixed: Slot selection reverting after a failed flash operation.
• Fixed: misc partition writes on devices that require it for boot control messages.

4. UI & Scripting

• Fixed: Occasional touchscreen unresponsiveness on devices with Goodix/TouchPanels after screen timeout.
• Fixed: twrp install command in shell ignoring -y flag (force install).
• Updated: BusyBox to version 1.36.0 for better cp, tar, and dd compatibility.

3. Failed to flash Magisk (Error 1)

• Cause: Legacy Magisk installer.
• Fix: Rename Magisk-vXX.apk to Magisk-vXX.zip and flash that. Or use the latest Magisk Canary build. The twrp-3.7.0-9-0 recovery works best with Magisk 25.0+.

Common install/usage steps (concise)

1. Unlock bootloader (device-specific; will wipe data).
2. Boot device into fastboot/bootloader mode.
3. Flash the TWRP image:
   • fastboot flash recovery twrp-3.7.0-9-0-.img
   • Or use fastboot boot twrp-3.7.0-9-0-.img to boot without permanent flash.
4. Boot into TWRP (volume/power combo) and make a full Nandroid backup.
5. Use Install → select ZIP/IMG or Advanced → Install Image to flash as needed.
6. Reboot system when finished.

2. Dynamic Partition & Super Image Handling

With Google mandating seamless updates and dynamic partitions (system, product, vendor merged into a super partition), older recoveries couldn’t resize or flash custom ROMs properly. Build 9-0 enhances lpdump and lpflash utilities, allowing TWRP to handle logical partitions on devices like the Pixel 6 series and newer Samsung Galaxy devices without manual command-line gymnastics.
