ASK/ACK Removal Tool for ASTRO25 RADIOS DO NOT BLAME US IF YOU GET FIRED FOR MESSING AROUND WITH YOUR WORK RADIO!!! IMPORTANT: This release is COMPATIBLE ONLY with codeplug/firmware structures of R12.00.00 or NEWER. ONLY PROCEED IF YOU ARE CERTAIN YOUR RADIO MEETS THIS REQUIREMENT. The P25 Forums technical team is pleased to present the following utility which will modify the codeplug partition of ASTRO25-family radios to remove the Advanced System Key (ASK) or Advanced Conventional Key (ACK) write-protection restriction. First, there are some things you need to know before using the attached utility. Technical background: This mod works on ALL ASTRO25-series radios. The ASK and ACK restriction is meant to restrict WRITE ACCESS in a CPS session, to authorized users only. But what happens if you purchase a used radio and it comes with the ASK or ACK protection enabled? You're screwed. Not anymore! The mod simply removes the "write protection" flag as set by the ASK/ACK. It's a one-bit value, contained at block 10, offset 48, inside the codeplug partition. Enabled is "4" (0100) and Disabled is "0" (0000). That's all! Nothing complicated. It's a very simple change to the codeplug which will not affect any other setting or programming configuration.
