Elation!!!!!!........ I found a fix.
I have a 7290 that was in a loop for weeks. When all else fails...follow the directions. There is an instruction about what to do when JL CMDR doesn't work. I tried it and was able to stop the loop and program the 7290. Well after this I thought I would try this on my 7280 with the 507 problem. It worked.. So, thanks to instructions, the program JL CMDR, and this forum I now have two almost dead Berries back to life.

Can somebody please help me? I've entered 10 times the wron password and now I have the 507 error code. I tried to use te application loader, but there is nothing to load on my pc. Can somebody tell what I need to download? And where? Thx!

i have 8700G that is unlocked...and i used Java Loader to wipe its memory b/c its bought second hand....now it has a 507 error...i have the latest desktop manager and device software...but when i try to install it using application loader it says i have no software for that device...im kinda lost now...do heLp!!!

Delete the vendor.xml file located in c:\program files\common files\research in motion\apploader and try it again.

My blackberry has the icon showing the circle, square and triangle as mentioned earlier, how do i reload the operating system?
I have a blackberry 7280 by the way.

Use the link below. Take the instructions as if you've already wiped the device with JL_Cmder. You'll need to install the OS to your PC in order to load the OS back to the device.
