Hello. My name is Michael. I can help you with your question today.
What is the exact error you are seeing. Is the script errror?
When that particular script error happens, it usually means you are going to have to do a fresh flash - earese, flash, erase, and do it with the entire Android image, not just the incrementals. That's what I would suggest doing - it would be best for the long run, as well.
It might be the process you are using.
First, do you have a custom recovery installed?
This is where I would start from:
The process, especially on older devices, is fairly complex. You must unlock the bootloader, flash a custom recovery, then you can restore a backup copy of the OS, or you can flash the OS from the custom recovery. I'm not sure exactly what procedure you are currently using with the PhoenixCard... but using flash_tool.exe is the most straightforward way.
