I have a friends Blackberry Bold 9000, and I am trying to fix it. The device is unbranded from RIM. And currently when plugged in states "No application linked (Factory OS)"

I followed these steps:

1. install the correct device software for your blackberry
2. delete 'vendor.xml' from 'C:\program files\common files\research in motion\apploader'
3. take battery out of Blackberry
4. connect USB cable to BlackBerry & PC
5. Open the command prompt
6. type in the command prompt: cd C:\program files\common files\research in motion\apploader
7. then type loader/nojvm
8. Click Next in the window that pops up
9. Click next again even if Correct PIN is not detected (UNKNOWN or FFFF..)
10. wait till app loader menu cames up and select components you want to install
11. Click next then again
12. wait for set to boot up
13. problem solved

The Application Loader comes up but is empty even though I have the OS 5.0 installed and ready to go. I tried downloading OS 4.6, but it still isn't working. "The blackberry desktop software does not have blackberry device software for the device that you have connected to your computer..."

On top of all this, the phone constantly resets itself every 15-20 seconds unless I use Desktop Manager or Application Loader to enter the Device ARM.

In Desktop Manager, I get an error saying that the device is unrecognizable and a "no pin" status.

The blackberry's pin is unrecognizable.

Any help would be appreciated!

"No application linked" - this means that MFI was used to unbrand it.
Is that correct?

The phone is from RIM, an official unbranded and unlocked phone.
Well that is what I was told.

Sorry for the scepticism; sounds like the phone was unbranded by using some software that was illegally obtained from RIM - that's the only time (ever) that I've seen or heard the "No application linked" error.

That process has been known to brick BlackBerrys.

Keep trying the process again (over and over) and it may work.

Will keep trying. Thanks!
