Under normal conditions all 3rd party apps will be backed up and restored. You'll need to reenter any registration/unlock codes for those apps, though.

If there is a problem with the loader process and you have to start over then you will lose the 3rd party apps but you can manually restore all your data with the automatic backup file.

i asked because i followed the instructions as per the op

i could not get dm4.7 to update the os to 110.

removed and installed 4.6 and although it is a lot slower to work with it did the upgrade.

i may now remove 4.6 and re install 4.7 to work with and then go back to 4.6 for upgrades only.

You don't need Desktop Manager in order to update your OS. Just go to C:\program files\common files\research in motion\apploader and double click on Loader.exe. It does the same thing but without Desktop Manager.

Even though we dont need desktop manager to upgrade have we found out why we are having so much trouble with dm 4.7? I used loader.exe to do my upgrade but also did all your suggestions from the original post. No go. Just wondering if we have found the hidden underlining yet?

Have an unlocked phone, afraid to upgrade
 

am living in India, hav a BB pearl 8100(RED) bought frm USA by my cousin. It is an unlocked one. It has a T Mobile Logo printed below keypad and AT&T logo during logon and shutdown screen. I am afraid that after upgrade it will get locked!!! Please tell me if there is anything like tht.

I also want to know what are things tht I wont b able to do on my unlocked phone when compared to a locked one.

Welcome to the Forums!

It sounds like you have a T-Mobile device that had been previously upgraded to an ATT OS. Pretty common, and nothing wrong with that. Upgrading your OS shouldn't do any harm to your unlocked status.
As far as limitations, it depends on your carrier and the OS version you decide to upgrade to. Most of the time there are no issues at all, but occaisionally, a carrier will not provide the Service Books for another carrier's OS. This could limit your web browsing capabilities as well as have an impact on other features.
This is pretty rare, however. I would suggest you try it, if things aren't working right, you can roll back to your previous OS. The link below should help you with this:

How do I downgrade the OS on my BlackBerry? - BlackBerryFAQ

Incorrect. Changing your OS will never re brand your phone with a different carriers logo. You simply have an AT&T phone that someone has used a t-mobile replacement part on. Once your phone is unlocked changing your OS will not lock it again. Ndub33 was right telling you that you might not get all your servive books. What carrier are you using in India?

Do we lose any of our data or settings when we upgrade? I want to change to a newer version bu dm does not back up my Bold.. Shall I risk upgrading without backup???

Great

Since the OS upgrade requires a backup to take place first as part of the process, be careful.

i would suggest you download a newer version of Desktop Manager and get a backup of your device.

Very nice!

Where did u get stucked, with with BB model??

Blackberry 8300 update
 

Hi,

I have a unlocked BB 8300 from O2.
I have tried updating my BB 8300 after I got a JVM error 102 by the techniques given in all the forum but still cant get it up and working.

After updating it, the device keeps on resetting continuously. I even removed the vendor.xml. Did everything possible that i could find in the forums.
What to do? Please help my device has been off for a couple of weeks now.

Thanks

So is DM 4.7 worth using?

Yes, DM 4.7 is worth using. It works very well. Also, you do not need DM to install an OS. You can use the Loader.exe file that comes packaged with the OS.

I am running DM 4.6. The other day I loaded the latest os for my 8820. Ido china or something like that. Well I played with it for a few days removing files and my ringtomes disappeared. Not knowing which module has them I played some more. Finally I did a factory reset and my ringtones came back. Well at that point I dumped my latest verson and went 1 revision back. I had to reload that update so my loader file was appropriate. (I think that is necessary) Well them I went to my DM, backed up my berry and did an update. It went through the process and added nothing. I did note that when I did an advance update all of the core stuff, MDS, Language an maybe more, no longer show up. My Berry works fine and see no problem on that end. Any thoughts?

Followed the procedures here as well and still my 8110 will not accept an update from 4.3 to 4.5. I honestly think that There is something physically on the phone that will keep this update from happening. After several texts from RIM about how I have to update it still doesn't work. I'd contact them, but unless they find the fault to be with them, which is solely at their whim I have to pay for any advice on their part. However, I don't see how I should have to pay for anything since I've followed all of their and your directions multiple times over the last 3 months and still can't upgrade to 4.5, even when AT&T offers the upgrade, this is ridiculous. iPhone here I come, I think..??..

Follow the instructions above. Make sure the vendor.xml file(s) are deleted then go to c:\program files\common files\research in motion\apploader and double click on Loader.exe to load the OS to your device.

Hi all. I'm new to the BB so I have a problem at updating. So when i want to update everything is going fine till i get to "Connect to the device ROM" after 5 min i get a message "unable to complete the update operation".

You could try moving the USB cable to different port on your PC.
