Re: rebootting problem

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:

  • KB17877 How to start a BlackBerry smartphone in 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!

Re: rebootting problem

Unfortunately, you've only given me a listing of new problems...no hint of what you did to cure the first problem, so I am left to guess.

 

Given all you describe, I'd recommend a total OS reload. 

 

Please refer to this official download portal as you proceed. It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.

From a PC, you can install any compatible (e.g., for your exact BB Model Number) OS package to a BB via this procedure:

Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC. After installing the OS package to your PC, please remeber to delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:

  • C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
  • C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML

Be sure that you remove, from your PC, any other BB device OS packages as having more than one installed to the PC can cause conflicts with this procedure.



You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.



You may also want to try the "Bare Bones OS Reload Procedure" to attempt to narrow down the precise causal item:

  1. Load your OS "bare bones"...if anything is optional, do not install it.
  2. If the behavior presents immediately, then try a different OS with step 1
  3. If the behavior does not immediately present, then run for as long as it takes for you to be sure that the behavior will not present.
  4. Add one thing -- no matter how tempting, just one.
  5. If the behavior does not present immediately, then again run for long enough to be sure it will not have the same problem
  6. Repeat steps 4 and 5 until all things are loaded or the behavior presents

When the behavior presents, you know the culprit...the last thing you loaded.

If the behavior does not re-present, then you know that either step 1 or 2 cured it.

If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.



You may also need the use of these tricks:



If you are on MAC, you are limited to only your carriers sanctioned OS packages...but can still use any levels that they currently sanction. See this procedure:

  • KB19915How to perform a clean reload of BlackBerry smartphone application software using BlackBerry Desktop Software

Good luck and let us know!
