Huawei Ascend G630 shows on the display: "Recovery image verify failed"
There is a quite simple workaround to solve your problem.


First you should search (on XDA example) and download an original-recovery.bin for your device.
After you can flash it in fastboot mode with the following command:


fastboot flash recovery original-recovery.bin



After this you have an original bootloader on your device.
