Yes, I carefully read all instruction and did accordingly to them, connected directly to the computer, no HUB. AND FINALLY I WON!!!
In my opinion problem is in newest version of loader (at least in my case). I found older Handheld software for ATT (even Cingular) and inject OS to BB from first attempt! It`s contain a loader.exe version 126.96.36.199. Thereafter I upgrade software in usual way with Desktop Manager. I think will be enough just replace existing loader v188.8.131.52 with older one.
I can`t attach file here, becouse file size exceed size limit for forum and I have to upload here
in case to save your time. Just unzip in C:\Program Files\Common Files\Research In Motion\AppLoader
, prior this rename your existing file (if you wish use him later). All rest according to instruction What to do next if Jl Cmder will not connect and wipe - BlackBerryFAQ.com
. Good luck!
P.S. Power Management of USB was disabled, but I think this is not so very important.
And sorry for my English...
