upgrading/downgrading 8330 for blackberry sprint

[bakso]

I have sprint 8330 but when I have wiped the device it turns out that I can only upgrade or downgrade 8330 OS released by Sprint and can not use other carrier's version.

However, If I use verizon, I have managed to downgrade/upgrade using different carrier's OS release version.


Can you guys tell me what happen to my phones? i tried 2 phones and they ended the same.

You have to delete the Vendor.xml on your computer.

I have deleted the vendor.xml but still when I run the loader.exe but still unable to upgrade/downgrade using other carrier's OS version

What version are you trying to install?
What exact steps are you following?

[bakso]

After I wiped and do a factory reset i install the other carrier's OS and then deleted the vendor.xml file. after that I run loader.exe but when the program went to chose the app selection there is not a single app that I am able to chose to install and the option is only to cancel the upgrade/downgrade process.

What EXACT device OS version are you trying to install?

[bakso]

I tried installing with various OS but no luck, the only successful install is if I upgrade using blackberry desktop software by downloading the upgraded OS. Somehow the desktop software ignored the local version of the upgraded OS. Below is the screen shot when I tried to upgrade locally.

Are you disconnecting from the internet before deleting vendor.xml? What version of windows are you using?

[bakso]

I use windows xp sp3. I have tried in the two different scenarios (connected and disconnected from the internet) but still no luck

[kbz1960]

Have you searched your entire hard drive for vendor.xml?

[bakso]

I just tried it now and did not found such file in my hard drive. But still I experience the problem. out of 5 phones, 3 are acting like these.

[kbz1960]

So you have successfully upgraded 2 of 5 exact phones with the same OS you're trying to install?

[bakso]

yes, the same model from sprint. Don't know what is wrong with the other three. they only succeeded when I connected to the internet and download the sprint's release (no other release can be installed)

[kbz1960]

Are you using the newest dm? I've heard if you're online it will redownload the vendor.xml file.

I don't really understand why you were successful with 2 and the other 3 will not using the same process. They are bis and bes with it policy on them?

[bakso]

yes I use the latest BB Device Manager but I double checked the vendor.xml file inside the AppLoader folder before up/downgrade.

about the it policy i'm not sure how to check it. can you tell me how to check it?
