**update**

I’ve tooled around with some REXX code to recreate the a.zip.pdb files from a custom ROM I created to remove PocketTunes, Addit and some other junk, and I’ve manually edited the MD5 checksum to match the new custom ROM. I just need to finish copying them to RAM and I’ll try what I believe to be the first custom ROM created for an unlocked GSM Treo 680 !

Yes, I have a custom ROM working, next on the list is recovery methods should anything go wrong.

    The FIRST custom ROM created for the 680, not possible before the above information and method was discovered and modified by myself and then shared to MFB and jamesgangut. Lest anyone forget :)
