Repair Guide
This page provides general information and guidance for repairing Anbernic RG DS consoles. It is intended for users with basic technical knowledge. Some procedures may void the warranty.
Important Notice
Proceed at your own risk. Opening the device or modifying internal components may:
- Void the manufacturer warranty
- Damage the device if done incorrectly
- Cause personal injury if proper precautions are not taken
Repairing Damaged Partitions Using SD Boot and ADB
If system partitions are damaged while attempting to modify the recovery, it is still possible to boot the console from a microSD card. This method allows repairs either by using the recovery environment stored on the SD card or by restoring partitions manually using ADB.
Case 1: Boot Partition Damaged (e.g. flashing a wrong recovery)
Step 1: Create a Bootable microSD Card
Create a microSD card using the official Anbernic flashing tool. Make sure to enable the option SD Boot during the process.
Step 2: Install ADB and Fastboot
Install ADB and Fastboot on your PC. You can find many tutorials online explaining how to install them for your operating system.
Step 3: Boot the Console
Power on the console. If the SD Boot was created correctly, the device should automatically boot into the recovery environment located on the microSD card.
Full eMMC Backup (Recommended Method)
Principle
A raw dump of the entire eMMC is created and then transferred to the PC. This is the safest and cleanest backup method.
⚠️ Requires free storage space equal to the eMMC size
Step 1: Create a Full eMMC Image
adb shell dd if=/dev/block/mmcblk2 of=/sd/emmc_full_backup.img bs=4M status=progress sync exit
👉 This backup includes everything:
- bootloader
- boot
- dtb
- recovery
- system
- userdata
- hidden partitions
Step 2: Transfer the Backup to the PC
adb pull /sd/emmc_full_backup.img
🎉 Full eMMC backup completed.
Restoring the Recovery Partition
Step 1: Verify Recovery Partition
adb shell ls -l /dev/block/by-name | grep recovery
Expected example output:
recovery -> /dev/block/mmcblk2p8
Step 2: Copy Recovery from microSD
adb shell dd if=/dev/block/mmcblk0p8 of=/sdcard/recovery_from_sd.img bs=4M sync
Verify the file:
ls -lh /sdcard/recovery_from_sd.img
Expected output example:
-rw-rw-rw- 1 root root 96M 2025-12-30 21:32 recovery_from_sd.img
Step 3: Flash the Recovery Back to eMMC
dd if=/sdcard/recovery_from_sd.img of=/dev/block/by-name/recovery bs=4M sync
Notes
- Be extremely careful when using the dd command
- Writing to the wrong block device may permanently brick the console
- Always verify block names before flashing
