Re: Help needed to upgrade OS on 9530
The 9530 uses both CDMA and, if unlocked, on GSM. Poor signal strength is a local issue and has nothing to do with CDMA.
The Vendor.xml blocks you from installing operating systems that aren't specifically branded for your (Telus) BB. Deleting it lets you install any 9530 OS, regardless of vendor branding. In other words, delete it and don't bother trying to understand what's inside the file.
