Important Disclaimer: Repacking firmware often voids warranties, violates EULAs, and can brick devices. This review is for educational purposes regarding the technical structure of the device.

5. Summary of Risks

| Risk Factor | Severity | Description | | :--- | :--- | :--- | | Hard Bricking | High | If a repacked firmware fails to flash and the device enters a "Qualcomm HS-USB QDLoader 9008" state (EDL), you may not be able to recover it without authorized service tools. | | Warranty Void | Guaranteed | Flashing unofficial firmware triggers the "System has been destroyed" flag or updates the Knox/Hardware fuse, voiding warranty instantly. | | DRM Loss | Medium | "Repacks" often break the Trusted Execution Environment (TEE). This results in Netflix/Prime Video playing in SD (480p) only, not HD. | | Banking Apps | High | Honor's security is tight; even with Magisk hide, SafetyNet/Play Integrity checks often fail on repacked firmware. | firmware+honor+pad+x9+repack

3. Step-by-Step Repack Procedure

3.2 Extract Images

• Open Huawei Update Extractor → load UPDATE.APP.
• Extract:
  system.img, vendor.img, product.img, cust.img, boot.img, recovery.img

Phase 3: Repacking the Image

Unlike standard ext4, repacking erofs requires the mkfs.erofs tool. Open Huawei Update Extractor → load UPDATE

1. Unmount the image: sudo umount /mnt/system
2. Repack using:

   mkfs.erofs -zlz4hc -d system_new.img /path/to/contents/
   

3. For cust.img (which is often ext4), use make_ext4fs.

Legal & Ethical Considerations

Repacking firmware for the Honor Pad X9 exists in a gray area. While modifying your own device is generally legal in most jurisdictions, distributing repacked firmware containing copyrighted Honor system apps is not. Use your repacked firmware only for personal use or authorized repairs. Moreover, this voids your warranty. Phase 3: Repacking the Image Unlike standard ext4,

4. Theoretical Repacking Workflow (Unsupported)

If you had an unlocked bootloader (impossible via official means), the steps would be:

1. Extract: HuaweiUpdateExtractor on update.app → get system.img_erofs.
2. Unpack: erofs-unpack system.img_erofs system_mnt/
3. Modify: Add/remove APKs, edit build.prop, or add su binary.
4. Repack: mkfs.erofs -zlz4hc system_new.img system_mnt/
5. Hex Patch: Update the image_header CRC using a custom Python script (Honor specific offset 0x400).
6. Flash: fastboot flash system system_new.img (requires unlocked bootloader).

1. The Firmware Structure

To repack, you must first understand the raw update package (usually update.app or full OTA update.zip).

• Format: Honor uses a patched version of the Huawei UPDATE.APP format.
• Partitions involved:
  • kernel (boot.img)
  • vendor (vendor.img)
  • system (system.img – often in ERofs format)
  • product
• The Block: Honor pads use CRC verification on every partition header. If you change 1 byte, the tablet refuses to flash via stock recovery.

Phase 2: Mounting and Modifying

1. Create a directory and mount the SYSTEM.img (read-write):

   mkdir /mnt/system
   sudo mount -t erofs -o loop SYSTEM.img /mnt/system
   

2. Make your changes:
   • Remove bloat: rm -rf /mnt/system/app/facebook*
   • Add root: Copy magiskinit and magisk.apk into /mnt/system/xbin/
   • Edit build.prop: Add persist.sys.root_access=1 or change region codes.
3. Note for beginners: Avoid modifying the framework res if you don’t understand dependencies.
