According to another .85 Thread, .85 is a very good release. It just depends on how you wipe and flash your Storm.
One person flashed it 100% successfully with no problems. I fallowed his steps and this is what I did.
If you are experiencing increased heat, very poor battery life and overall instability, UNINSTALL .85 NOW before it permanently damages your device.
Here are the steps I took:
1. Uninstalled all BlackBerry Software, including the option "remove all user settings".
2. went to the directory c:\program files\common files and deleted any blackberry or research in motion left overs.
3. went to directory c:\program files and deleted any blackberry or research in motion left overs.
4. Rebooted PC
5. Installed .85 package
6. used JL_Cmder and did a clean whipe on 70% battery power (100% recommended)
7. went to c:\program files\common files\research in motion\apploader and deleted the vendor.xml file
8. Now to install the firmware properly, I fallowed the steps from
This Thread.
9. Once that finished, I then installed Desktop Manager Software 4.7. Got the 1904 error.
10. Rebooted PC
11. Fallowed steps in
This Thread to fix the 1904 error and register DLL's manually.
12. Rebooted PC
13 hookup the Storm to Desktop Manager and restore your backup config, if you have one!
And your done! device is now working 100%. awesome battery life, good speed, no signs of over heating or any of that nonsense.
