E6 - Opera Mobile crashed and took numerous applic...

Question

At a certain point of time 3 days or so back, Opera Mobile showed one of the many "General .. Memory full" errors. After a few minutes it just froze along with the OS. I had to long press the power key for >5 seconds to shutdown the phone and restart it.
Now I have seen that more than 10 various applications have simply disappeared from the phone. Eg:
1. Opera Mini
2. Opera Mobile - Its icon is there but it is not launching
3. Facinate
4. Nokia Drop
5. NSR Reader - Free version
I am sure some more are lost because the number of icons in my applications folder is less than what it used to be.
I also have 2 more unknown "?" mark shortcuts on one of my homescreen shortcut bars. (Right now I do not remember which applications they connected to)
I have reinstalled some of the missing applications resulting in a few shortcuts coming back to life.
But I had to manually download from Nokia Store and install them direct as .sisx files because whenever I tried to do the same using Nokia Store application, it failed leaving behind the Smart Installer icon active in the Applications folder. If I tried to continue the installation as advised, it would just dump me back to the same Smart Installer.
Any help, suggestions, similar experiences?

Answer 1

Thanks for the suggestions. I really regret not doing bi-weekly backups.
I have a few concerns though:
1. I had failed to mention in my post above that I am still running Anna. I do not plan to go Belle until most of my concerns are addressed by a future update or I change my mind
If I use Nokia Suite to reinstall the firmware, will it push me into Belle?
2. I have many applications installed from outside the Nokia Store such as mIRRGI. I may not have the installers for all of them now.
3. I may have more than 50 applications installed from the Nokia Store itself. It will take a longtime to cull them from my tried applications list of more than 200 and install.
4. I had organised my applications into folders such as Games, Office, Internet, Media, System etc. Moving all the reinstalled ones to that structure is another hour at least.
5. I had saved text messages into organised folders. Nokia Suite does not respect that and it will restore them where ever it feels like, not always completely.
With my tinker and learn mindset, I find this wipe and reinstall kind of solutions less palatable.
I suppose we will all be more wiser if a specific diagnosis be made and a solution found.
Until then I will either keep exploring or failing which --- Wipe and Reinstall ha ha.
