I'm having a little trouble. I am trying to downgrade my OS from 4.5 to 220.127.116.11. I usd jl_cmder to remove the os and I am now at the 507 screen. I downloaded the 4.3 Alltel OS from the BB website and installed it on my pc. I go in to the app loader folder and delete the vendor.mxl file. I start the loader and it detects my blackberry just fine. But then comes the screen that says it is reading my device service info. It goes through that process and then shoots to the next screen and says it doesn't have any software for the device I have connected. I'm stumped. I checked to make sure that the Alltel 4.3 OS was installed on the pc and it was (even uninstalled and reinstalled). If anyone could help me with this I would really appreciate it. And just so you know I am using Blackberry Desktop 4.6 with an Alltel Blackberry Curve 8330.
