If you try to flash any other OS, then there is a good chance of bricking the PCM. The best course of action is to read the 0411 PCM with this flash tool, and then to only reflash the PCM with the base calibration previously read out. You can alter this base calibration as necessary, including swapping various segments.

Also, if you try to flash a 9354896 PCM (1999 & 2000), which is often used as an 0411 replacement, there is a good chance of bricking the 4896 PCM.
So you're saying the OS's don't work on that hardware, or dimented's program is flawed?
The program is a flash tool, and a binary is a bit perfect copy of the data, so if the flash chip is identical, why would the difference in OS matter if its copying the whole contents?
Also the first PCM was the 411pcm and compatible tune, theOS that brickjed that was the 12208322.

I know the fault was mine four trusting home brew software instead of buying the commercial option, but I thought he had put together a working program.
