Check that you have deleted ALL the vendor.xml files on the computer. thsi is necessary for making the connection of mobile phone with this laptop system. try this and check the mobile phone connections. if your mobile connect try to do the update task on it.

if main problem is related to connectivity of the mobile phone with your laptop, i recommend to replace your USB cable. yes, it might be possible that problem is being present on your cable connections. try this and check what things happen onto it. it could be fix your connectivity problem. if mobile connected to laptop, try to do this BB OS 7 update task with the help of BB desktop manager.

if still it gives similar problem, there is necessary to confirm the BB mobile phone is being compatible with this BB OS 7. if you confirm about this compatibility, then try this update process. otherwise all are just waste.

Thanks Donatien, I've now followed your advice in the first post and it works to get more information about this smartphone. With the help of this checking confirmation task, all the result helps me to perform this update task in proper way. Then i download and install this updated BlackBerry os 7 on my smartphone.
