⚠️ WARNING: THESE PROCEDURES ARE HIGHLY EXPERIMENTAL ⚠️ Modifying low-level partitions can permanently brick your device. Proceed ONLY if you fully understand the risks.

Repair Guide[edit]

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[edit]

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[edit]

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)[edit]

Step 1: Create a Bootable microSD Card[edit]

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[edit]

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[edit]

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)[edit]

Principle[edit]

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[edit]

abd shell
# create sd
mkdir /sd

# reset
dd if=/dev/zero of=/dev/block/mmcblk0p15 bs=4M count=10
sync

# format
mke2fs -t ext4 /dev/block/mmcblk0p15

# monter
mount -t ext4 /dev/block/mmcblk0p15 /sd

# backup eMMC
dd if=/dev/block/mmcblk2 of=/sd/emmc_full_backup.img bs=4M
sync
exit

👉 This backup includes everything:

  • bootloader
  • boot
  • dtb
  • recovery
  • system
  • userdata
  • hidden partitions

Step 2: Transfer the Backup to the PC[edit]

adb pull /sd/emmc_full_backup.img

🎉 Full eMMC backup completed.

Restoring the Recovery Partition[edit]

Step 1: Verify Recovery Partition[edit]

adb shell ls -l /dev/block/by-name | grep recovery

Expected example output: 

recovery -> /dev/block/mmcblk2p8

Step 2: Copy Recovery from microSD[edit]

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[edit]

dd if=/sdcard/recovery_from_sd.img of=/dev/block/by-name/recovery bs=4M
sync

Notes[edit]

  • 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
