BB 8520 @ MTN - BB APP WORLD DISAPPEARED.

[ Edited ]

I have upgraded BB8520 TO V.5 AND.... the BB App World and the n Browser has disappeared.I decided to RESET the BB and reinstall The BB HANDHELD SOFTWARE onto my Phone via the DESKTOP Software.

I have even downgraded the OS to version:4.6 and same.On the Desktop Software it shows it is there, but on my Phone nothing.I have never Back up THEIS PHONE, THUS i CANNOT RESTORE.

Re: BB 8520 @ MTN - BB APP WORLD DISAPPEARED.

Hi and Welcome to the Community!

I suggest a very clean OS reload. The simplest way is to, on a PC (you cannot do this on MAC):

1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below. As you say, this is now moot in your situation.

2) Uninstall, from your PC, any BB OS packages

3) Make sure you have the BB Desktop Software already installed

4) Download and install, to your PC, the BB OS package you desire:

  • http://us.blackberry.com/support/downloads/download_sites.jsp
  • It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.

5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:

  • C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
  • C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML

6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.

6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:

If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.


 

Once complete, the first thing to do is with a strong carrier network signal (e.g., not merely WiFi), I suggest the following steps, in order, even if they seem redundant to what you have already tried (steps 1 and 2 each should result in a message coming to your BB...please wait for that before proceeding to the next step):

1) Register HRT

  • KB00510 How to register a BlackBerry smartphone with the wireless network
  • Please wait for one "registration" message to arrive to your Messages app

2) Delete and Resend Service Books

  • KB05000Delete the service book for the BlackBerry Internet Service email account from the BlackBerry smartphone
  • If you have no CMIME entry, then skip the deletion
  • KB02830 Send the service books for the BlackBerry Internet Service
  • Please wait for "Activation" Messages, one per already configured email account, to arrive in your Messages. If you have no already configured email accounts, please wait 1 hour.

3) Reboot

  • With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes.
  • See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure.

If BBWorld is still not there, then please try this sequence:


1) Remove AppWorld from your BB

  • KB10040 How to view or remove installed applications on a BlackBerry smartphone
  • If it requests that you reboot the BB, do so

2) Do a Batt-Pull reboot (power on, remove battery, wait, insert battery, wait), even if redundant to the one you did in step 1.

3) Install (on your BB) a fresh copy of AppWorld

4) Do another Batt-Pull reboot

5) See if it now works.


 

If all fails, then contact your mobile service provider for formal support.


Cheers!

Hi alimayet,

 

After the 02 options given to you before are done if you have the problem.

There is an IT option which is in 4.6, which can be removed through bbsak.

also load the latest version through

.

you may have your problem resolved.

Do write back if resolved.

 

Good luck
