Go to Solution.
517 is unrecoverable. Your carrier will need to replace the device if it is still within the 1 year manufactures warranty.From RIM KB Article directly.http://www.blackberry.com/btsc/KB19442
Can I install a new software ?
Its already more than one year actually
Yes you can try it. And try different updates till you get it right.
