Hello, thank you so much for the useful tool.
Is there a way to re-sign a signed img after using?
Or to unsign the entire ROM so that won't brick when I flash unsigned img?

packing doesn't work, if you really need to reflash the un-signed image then unlock bootloader of the device and flash the image using fastboot

unlock bootloader ; see https://www.hovatek.com/forum/thread-19578.html
flash through fastboot e.g
fastboot flash <partition_name> <path_to_file>

certain tools can't work with the signed images until you've removed the signature
