ATT 8310 Reinstall Original OS using a Mac



Carrier: ATT

Curve: 8310

OS: 4.5

Problem: No network connection


One of my 8310's has beeb acting up. After connecting to my Mac's BB Desktop manager, it showed OS upgrade avail. Did it, BB worked fine.  Next day however it showed "SOS" and now no network connection.


So far I 've tried:


- check all settings, all seem ok, connection turned on, etc.

- Tested SIM card, Ok, tested in another 8310 works fine.

- Did both soft, hard resets, no luck, no network connection

- Checked netwrok settings, no network shows ups (again SIM ok in another device)


** I did notice 3 service books missing compare to my other BB 8310: BBIM Config, CMIME, OTASL


Best I can come up with is delete and re-install OS. Can you help as to how? (using my MAC ?) or is there another solution?


Thank you

Hi pespinoza,


Welcome to the BlackBerry Support Community.

Try backing up your BlackBerry and following the steps in this article to clean reload the device software.  http://bbry.lv/izhqIz When the software reload is finished, before you restore your backup file, try to register in the Host Routing Table to receive your service books. http://bbry.lv/pTiRCV  Then test further network connectivity before restoring any information from your backup file.


Hope this helps.
