Re: BATTERY DRAIN

You'll need to do a clean OS reload.  

 

From Control Panel >Add/Remove Programs remove any OS installation packages you may have installed.  Then do the following:

 

1. First locate your carrier and the OS file you wish to use.

http://na.blackberry.com/eng/support/downloads/download_sites.jsp

2. It doesn't hurt to do a manual backup of your device first, using Desktop Manager > Backup. Close Desktop Manager upon completion and unplug BlackBerry. You can get BlackBerry Desktop Software here http://us.blackberry.com/apps-software/desktop/

3. Download the OS file from step 1 to the PC then install it to the PC by running (double clicking) the file you downloaded.

4. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml." Also check the following locations for vendor.xml files and delete any instances of the file:

On Windows Vista/7 navigate to C:\Users\YOUR_USER\AppData\Roaming\Research In Motion\BlackBerry\Loader XML (Where "YOUR_USER" is your username)

On Windows XP navigate to C:\Documents and Settings\YOUR_USER\Application Data\Research In Motion\BlackBerry\Loader XML (Where "YOUR_USER" is your username)

5. If you're simply updating the OS to a newer version skip this step. If doing a clean OS reload use BBSAK from BBSAK.org and wipe the device (after doing a complete backup) then after you get the error 507 (no OS installed) then proceed to next step.

6. Plug in BlackBerry and double click on "Loader.exe." It's located in c:\program files\common files\research in motion\apploader

 

you can then reinstall any applications and restore the backup file.

Re: BATTERY DRAIN

Not really. You can skip the bbsak wipe if you want and try to do a downgrade rather than wipe and reload but I've found that causes problems sometimes.
