How to: OS 4.x Upgrade for your Blackberry

twheeler · 07:21 PM

Here's a quick How To on installing 4.x.

Follow these instructions exactly and you should be able to have OS 4.x working.

1.) BACK UP YOUR DATA! - I can't stress how important it is to get a good backup in the event you need to restore your data.

2.) Verify that you are using the latest version of Desktop Manager. Open BlackBerry Desktop Manager. In the Desktop manager program on your PC use the Help menu and select About Desktop Manager. If you need the latest version follow this link.

3.) If you haven't already, download lastest OS 4.x from this link or if available from your carrier its BEST to download here (select carrier)

4.) Install 4.x using the .exe file you just downloaded. If you are downloading the OS specific for your carrier you can skip step 5. I other words if upgrading a T-Mobile BlackBerry with T-Mobile OS then you can skip this step. However, if you have an At&T Wireless Blackberry and the OS is non-At&T eg. from Vodafone, you MUST follow step 5.

5.) Delete the 'Vendor.xml' file ( C:\Program Files\Common Files\Research In Motion\AppLoader ) Or search your computer's hard drive for the "vendor.xml" file. Once you find it, delete it.

6.) Connect the BlackBerry device to the computer. If prompted, type your BlackBerry device password and click OK.

7.) Open Desktop Manager. It should recognize that there is an upgrade for your device. ('Vendor.xml' must be deleted for this step to work).

8) When the Application Loader Wizard is finished examining the configuration on the BlackBerry device, the Device Application Selection screen appears listing the applications and OS version available for installation. The selected check boxes indicate applications that are already installed on the BlackBerry device.

9) If you didn't backup first you should select to do so now.

10) Follow the prompts and you will have OS 4.x installed in about 15 to 20 minutes.

Good luck and of course, myself nor Pinstack.com can take responsibility for any problems that may occur. I will however extend my assistance if you need it.

Note:
If after OS install while connected via USB the hour glass spins allow your Blackberry at least 20 mins to load Do Not unplug

I just finished installing it on my 7100g, It seems to be working fine. Towards the end of the install, my office had a power outage and it didn't finish the install. After everything was back up it just picked up where it left off. I had to do a manual restore. All my info is in it and ready to go.

I have noticed one thing so far, the BB insight-Icon theme makes it run slow. I will try out others and see if there is a difference. I am also going to try to download some and see if those make it slow too.

Next up is my 7290.

Butterfly was GREAT! Good job. What we learned was pretty cool too.

You don't need DM 4.1 for the upgrade to go perfectly.

If you have custom ringtones already installed, they will be retained during the upgrade to 4.1!

Good stuff.
