BlackBerry® Curve™

[cassie46]

Today I downloaded a app and then I decided I didnt want it so unistalled it in which it then said I needed reboot/reset so I clicked yes and then it will not come back on now. At times the light flashes red but nothing happens. I have tryed charging it, taking battery in and out. Any advice would be grateful it is only about a month old.

First, remove the battery for about five mins and reinsert to try a reboot.

If that works, good.

If not, see below.

If your BlackBerry stays powered off with a black screen, follow the instructions below. The only indication of life might be the blinking red LED light in the top corner. Nothing seems to wake it up and Desktop Manager doesn't recognize any device is connected.

1) Make sure you have Blackberry Desktop Manager installed.

2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):

"c:\program files\common files\research in motion\apploader\loader.exe" /nojvm

3) The Application Loader Wizard will appear -- click "Next."
4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. 

Just don't disconnect anything and let the lengthy process finish completely.

NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device.

Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.

I have tried downloading the operating system via the link provided I select orange uk network and then click on download blackberry device and desktop manager it then asks me to select my product which is not on there (8520 curve) any suggestions

[cassie46]

This is what I have done up to now. I have downloaded desktop manager and the message came up no software found so followed instructions on the note section. When trying to download desktop software it was not coming up with the 8520 so I have skipped this as I presume this is the same as the desktop manager is this correct? I am now in the process of downloading this onto my computer )see below for details) is this correct? Then I just re follow previous steps?
