Nice job on the post!

But now I have been using DM 4.7 and just got the DM 5.0. I seem to have the issue of the downgrade of Documents To Go. I tried to follow the instructions on how to disable this issue from the post, but there is no such folder (C:\program files\common files\research in motion\shared\Loader Files.....). Can someone help me to figure out how to resolve this. I have some other Apps I want to load, but because of this issue, I can not proceed. It will either downgrade or remove it. I am unable to disable or delete it from the list.

Please, any suggestions? ( I have read everything I can so far on the web and nothing is helping or working!!

Install your version of the handheld OS to the PC. Then delete the vendor.xml as as explained. Once the handheld OS is installed then you can go delete/rename the DocumentsToGo.alx file to DocumentsToGo.old. Then Docs to go shouldn't want to downgrade.

I prefer the e3 its dosnt budge and gets in there good, but its really what you do good with, everyone is different:cry:

trouble with my BB
 

I recently wiped my BB cause i received an error message(application error205)now each time i try to reinstall the OS i received another error that prevent the OS to be installed.Can somebody help me.

Search your PC for vendor.xml and delete any instance of it. Also, if you could post the error you're receiving, it may help.

For upgrading OS, I have never wiped my phone (there was that time when i thought I nuked it) but i don't wipe it when i upgrade. never had an issue

Mods - please weigh in here if you can - is point 6 still valid in the original post? Is there ANY difference between a beta and official if app/package versions still the same? Many people on bbhybrids and cb are saying there are some differences between the tour .419 beta leak and the mts official release.

OS Upgrade for unlocked BB
 

Hello,

A really comprehensive myth buster.. Thanks! :)

One question though - Will upgrading the OS on an UNLOCKED BB relock the phone? Any precautions to be taken prior to upgrading?

Thanks!

There's nothing you can do to relock your phone.

Read the threads on the latest OS version you are installing. If you're satisfied then go ahead with the upgrade. You can always downgrade back, if all else fails.

thanks for the info

good post lot of people always get scared upgrading from other sites

Re: BlackBerry OS (and "Beta" OS) Upgrade Myths Dispelled:
 

Possible addition --

If you upgrade, some games will lose their progress and you will have to start over. Examples are shoppers paradise, bubble army2, and civilization.

That's not a myth. ;-)

i have brought an unlocked phone blackberry 8830. do i need to unlock it again after upgrading the OS?

Re: BlackBerry OS (and "Beta" OS) Upgrade Myths Dispelled:
 

Nope. Once unlocked, always unlocked. It's not an iPhone.
