I'm sure it requires you to reinstall the phones firmware. Go to the following link to download the firmware:

Hi,

Error 507 appears when any subsequent attempts to perform an Application Load or upgrading the software
on the BlackBerry smartphone are unsuccessful

Solution :
1. Connect the BlackBerry smartphone to the computer and open BlackBerry Desktop Manager.
2. Click on the Application Loader icon.
3. Click Update Software.
4. Type your BlackBerry smartphone password (if prompted) and click OK.
5. Select Options under the Device software options section.
6. Select the check boxes next to the names of the applications you want to install.
7. Click Settings, and remove the check mark from the check box for Back up device data automatically during the installation process.
8. Click OK.
9. Click Next > Finish.
10. When the process has completed, the message The loading operation was successful will appear. Click Main Menu to return to BlackBerry Desktop Manager.

If it shows the same error then please visit to the nearest Service centre.

well you have done great so far. Error 507 means that JL-CMDER has done its job and wiped all applications off your phone. So just do the next step by connecting it to your 4.7 Blackberry Desktop and select App Loader and install the OS and Applications on the phone. Please write again if you need more help

ur **** get a new phone

507 means no operating system found. You will need to reload the OS.  Device may require a clean wipe and re-install of the OS.

The 507 error means that the operating system is no longer on the device. Any data on the device is gone, too. You won't be able to retrieve it unless you have a backup.

You will need to reload the operating system on to the device. You will need the Desktop Manager program, along with the BlackBerry handheld device software.

You can find the Desktop Manager program here:http://na.blackberry.com/eng/services/de...

You can find the lastest BlackBerry handheld device software from your carrier's site. A list of them is here: http://na.blackberry.com/eng/support/dow...

And you can follow these instructions for upgrading your operating system:

Hi Anand

Practically speaking i spent 3 hours looking for your solution but nothing much even the BB intelectuals failed .Try these steps out it may resolve the issue and lets hope for the best .

This error : 373 : Device Error means that the Timers are corroupted

1. Remove the battery for at least 5 minute.
2. Make sure u have working SIM card, other wise remove the old SIM.
3.You should receive an Hour glass spinning. Give a few minutes, after that u will see a 507 message on the bb screen, (which means there is no app loaded on the bb)
4.If this dosent work
Use application loader to wipe handheld clean and reinstall base software but do backup your data

And please let me know .

you need to reinstall the OS!

Go to blackberry.com and download blackberry desktop manager!

and then you need your phones os which can be found at nextel.com
