At me a problem: earlier бб wrote a error 365. I did not touch its couple of months and have now included and it writes a error 66. Now I connect it to пц and it constantly does restart that пц cannot define it. And when I disconnect that writes a error 66

Has noticed such thing 1. That when on PC it is not established Desktop Manager that BB in restart does not go at his connection to PC as soon as I establish Desktop Manager so starts to go to restart. 2 could begin installation OS but at a stage " wait for device initialization " to me writes " unable to reconnect to the device during a multi-stage load operation " as it can be bypassed or what will advise to make?

You need to connect the BB to a different USB port. Do not use a hub. Try another port and start over.

Connected to different ports USB then connected still to different Pc. The situation identical before installation Desktop Manager is defined normally and as soon as I establish Desktop Manager so begins constant restert bb. Who can that advise?

wipe handheld then reinstall system software
