Yes it does show Firmware mod by MrWalkman, I used your firmware and now wanted to install the latest you made off the A50
It is a NW-A45
Ok, I'm sorry, but what did I say here:
Nothing can be installed (except the external tuning from the second step of the installation process, or the StockRevert package) if you don't revert to the stock firmware first, as instructed there.
There is all sorts of info on each firmware's page, such as how to revert back to the stock firmware:
