Use the Huawei Update Extractor Tool to extract an original RECOVERY.img directly from the official stock UPDATE.APP firmware file.
Once the extraction is complete, navigate to your extracted_images folder. Among the extracted files, you will find a file named RECOVERY.img . This is the original, unmodified recovery image that should match your device's bootloader. This file is the key to resolving the "verify failed" error.
To attempt this, you must set up a TFTP server on your PC, configure its IP address to match the recovery mode's expected network settings (often a static IP like 192.168.1.100 ), and place the correct firmware file (likely UPDATE.APP ) in the TFTP server's root directory. When you boot the device in a specific way, it will automatically try to connect to the TFTP server and download the firmware. This is an advanced procedure and should be researched thoroughly for your specific chipset. huawei s7721u recovery image verify failed repack
Ensure the kernel.bin , rootfs.img , and app.img are present and uncorrupted.
The mention of "repack" suggests you might be looking into re-packaging or re-flashing the firmware or recovery image to resolve the issue. Here are some general steps and considerations: Use the Huawei Update Extractor Tool to extract

The Recovery Image Verify Failed error on Huawei Quidway S7700 series switches (including the S7703, S7706, and S7712 models utilizing various main processing units) typically occurs during a system upgrade, boot recovery, or signature validation process. This error indicates a cryptographic or structural mismatch between what the BootROM/BootLoad software expects and what the system file ( .cc or recovery package) provides.
