The exact steps should work on a CECH250.A shouldn't they? I first did the steps manually, then ran the script but both resulted in seemingly encrypted garbage (no strings found and nor were erk or the riv saved on 0x00-0x20), I'm using the 3.55checkoff.pup from the "Downgrading with NOR flasher" talk page which seemed to have the SS patches because that is how I retrieved my eid0. --Afiser 01:46, 2 January 2012 (CST)
Metldr dump can be achieved without using Otheros++:
- Install Red Ribbon (even on external HD).
- Enable SS patches.
- Follow the rest of steps.
