My 9700 has pretty much given up due to App Error 523. It just appeared randomly, when no new apps etc had been installed. It boots, and initially went to about 85% verifiying security software, then displayed the error, although it has got as far as displaying the clock (when on charge/usb) for a moment or two before then displaying the error.
I have attempted to use the "restore a nuked BB" instruction without much success, and also the online update service, but it seems that as soon as the error message appears, the process is unable to continue.
It was purchased as an unbranded phone and uses a mobily SIM and I have been trying to avoid using a branded OS download. Does anyone have any bright ideas? I will suffer a branded OS if it means getting my BB back and working!!! (As long as it still connects up with Mobily [Saudi]). I have tried to get the Mobily OS from RIM, but the page displays an error.
Hugely grateful for any help
