BlackBerry® Curve™

[mairay]

I was just using whatsapp before this and it was going very slow and then when i would click on whatsapp, there would be a message saying uncaught exception or something like that so then i pulled the battery out and it never started properly after that but would just load the bar about 2/3 of the way and then stop.

i've tried charging it, it was fully charged before though and i've left it out the whole night and it still isn't working?

its a Curve 8520 with OS v.5

Hi and Welcome to the Community!!

There's pretty much no diagnosing those -- they are the equivalent of the random errors in Windows for which tracing the root cause is fruitless. Basically, these are the last out in the programming code -- some event occurred for which there is no handler in the code. The fix is a code update that handles the event...but, again, knowing what the event is is pretty much impossible. So, there are a few things to try:

---

Sometimes, the code simply becomes corrupt and needs to be refreshed -- just like a reboot:

• Anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop 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 it won't boot up cleanly, then you may need to try Safe Mode:

There might be an updated code set from the carrier -- check them via this portal:

The toughest possible cause is a badly behaving app. To find it, there are a couple of options. One is to see if you can read the log file:

Go to the home screen. Hold down the "alt" key and type 'lglg'. (You will not see anything while you type).This will bring up the log file. Scroll down (probably many pages) untill you see a line that says 'uncaught execption'. Click on this line. The name of the app will be in the info. Alternative methods for bringing up the logs are in this KB:

• KB05349How to enable, access, and extract the event logs on a BlackBerry smartphone

The other method is to remove apps one at a time, waiting a while in between (I usually recommend a week), until the problem ceases...thereby discovering the offending app. Still another method is to reload the BB OS cleanly, leaving some time between adding other apps onto the BB so as to be able to determine exactly which one is the cause.

Good luck and let us know!

Hi and Welcome to the Community!

Well, if you have the same problem, does not the reply, just above yours in post 2, also apply to you then? As such, you should read it and attempt the various remedies that it contains, reporting back with specifics of how things work or do not work.

Good luck!
