<Solved> Bricking P-01s with PCMhammer and Unable to Recover

[antus]

You would be able to fix the bricked P01 with a uLink-NT from https://www.usbjtag.com/ but it requires the hardware and soldering or at least electrical connections. That hardware connects in to a debug port (BDM) on the CPU and you can re-write a flash chip directly without the PCM running. See https://www.youtube.com/watch?v=vNw7D10Znmo for an example, and note that he is using the older USB-BDM-NT and the pins on the device are in different locations to the current uLink-NT, so you'd need to check the 'connections' information in the software when wiring it up rather than copy the device side connections from the video if you bought the newer tool.

Thank you for that, I'm going to watch that video and if the hardware is "cheap" or I can see other uses for it my tinkering side might have fun with that. All that said, a quick gut check tells me that spending $40 at the scrap yard and calling it quits on the bricked computer if I want a spare might be the right call... I'm not sure this will be worth my time right now but it is good to know that there is an option to recover it. Thank you for the insight / information!

Yeah that hardware is $72 USD in their store at the moment so if you can get another PCM for $40 and its a one off, then not worth it.
