Blackberry 8320 CSL Version Upgrade Failure.
 

I have purchased a Blackberry Curve 8320 from China. It stated unlocked and new at a good prices. So I purchased it, and the reviews from all the people where great. It came and as advertised it worked, but when I updated the Desktop Manager to 4.7 it offered me the choice to upgrade to Version 4.5.0.124. I thought great. Because the current version was 4.22.134. During the update it gave and error, something about loader issue. The phone was now stuck in a reboot cycle.

I followed the instructions to repair a nuked bb. and after trying every other version, used back 4.22.134. No other version will load onto the device.
I keep getting errors 317, and 424.

I have tried MFI Multiloader, full clear and it still wont upgrade. I have used the J_cmder and to wipe the unit and it still doesn't upgrade.

Can anyone shed some light on this topic.?
