Wondering if doing this changes any bytes in the image?</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size:
13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">Also, I'd like to see if the few bytes after id (AH015) are indeed sub-model specific,</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">as I have seen those change when one fools with configuration diodes such as US vs EU</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">(and - cough - widebander mods...).

You can do a mod, reset,</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">and the bytes will change. Old image (without modifying those bytes) will fail upload.</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">However, what is interesting is, that if you dont reset, the previous image will continue to run</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">(and radio will use that software configuration, despite hardware
diode config). </div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;"><span style="background-color: transparent;">i.e., you can do the following:</span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">1. do the hw mod and <span style="background-color: transparent;">reset</span></div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">2. download the new, empty image, populate channels, and reupload</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida console', sans-serif; background-color: transparent; font-style: normal;">3. undo the hw mod, but dont reset</div><div style="color: rgb(0, 0, 0); font-size: 13px; font-family: 'lucida
