Official OS6 on 9700

Hello everyone,


Finally, I got official OS 6 on my 9700. It is from Mobilicity in Canada.


Here are the steps I did:

+ Did the OS update from www.blackberry.com website

+ Did a memory wipe.

+ Restored my old data


I am still getting memory leaks. at the beginning I had 74MB application memory free. but it keeps going down. Yesterday, it reached 6.5MB free memory. Does anyone know how can I restore this leaked memory. Specially that I dont have lots of applications.

Hi and Welcome to the Forums!


Memory leaks are typically caused by badly behaving applications. Diagnosing is a matter of not launching any of your add-ons and seeing if things stay stable. Then launching only one add-on at a time until the behavior returns...at which point you have your culprit. It is time consuming as you need to leave enough time between actions to ensure that memory is or is not leaking.


Further, it is always important to properly close applications when you are done with them. Using the Back or the Red key will not do this -- those leave it to the app to decide what to do...and some will leave themselves resident in memory, consuming resources on your BB, slowing the overall performance. Rather, to close an app, press blackberry_logo.jpg and select "Close" or "Exit"...that will force the application to be closed, freeing up for your new use the resources it was consuming. Some apps will always remain running (typically -- BBMessenger, Browser, Homescreen, Phone, and Messages)...but, you should still close them properly - especially the Browser...if it is left on an active web page, it will not only consume extra resources but battery power as well.


 Good luck!

Re: Official OS6 on 9700

One other thing to do if you haven't already is to do a battery pull.  There should not be that much of a memory leak, suggesting that something is wonky. 


A battery pull may resolve the memory leak, or you may need to reload the OS using the strategy described in the following link.  The website upgrade should work, but there is less of a risk of things going wrong when you use the manual download/installation method.




If you do end up reloading the OS using the method above, you shouldn't really see much of a memory leak.

Re: Official OS6 on 9700

Thanks a lot for your help. It looks like OS6 is not mature enough to run on Bold 9700. I installed on my phone, and did not use the phone for 8 hours (No applications running). And still the app. memory went down from 70MB to 30MB.

I have gone to OS5.

Thanks again for your help
