hello every one , i hope some one can help me my kids got hold of my bb7290 and now it shows a message 507. what does it mean and how do i get it working again.help!!!

Had you done a search on "507" you would have found that it means the OS is either missing or has corrupt files.

You will need to wipe the device using Jl_cmdr and then reload the OS. Make sure you install an 7290 OS and remove the Vendor.xml file before you try the install on the BB.

You find Jl_Cmdr info in our FAQ. You will find OS info also in the FAQ.
