9930 freeze when without USB connection

my 9930 only works once USB cable connected or charger. without these connections, screen are dimmed or freeze...cannot do anything.

I have tried with many OS, but cannot fix. Not sure it is hardware or software issue?

Current OS: from verizon


Anyone has the same problem?

Re: 9930 freeze when without USB connection

Hi and Welcome to the Community!


That is a very odd symptom...I'd recommend trying a couple of things...


I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.


If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.


You may also want to try a device OS reload.

At the top of each device forum, there should be some "sticky" threads that discuss the OS levels available for many models. If they include your model, then please use those as reference as you proceed. Otherwise, you will have to dig through the official download portal for OS packages for your model:

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. If that OS package is from a carrier other than the carrier for which your BB was originally manufactured, then 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 this procedure to perhaps 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.

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!

Re: 9930 freeze when without USB connection

I have had the same problem now for weeks and i am about to throw the phone against the wall!


I will run through the suggested options with bare OS load etc. but my patience is thin.


trandat: did you get resolution?

Re: 9930 freeze when without USB connection

Working my way through this.


Safe mode does not resolve issue.


I am successful at getting my 9930 into safe mode (only after required battery pull) but seems to lock up same as before within a minute or so of startup if not connected to USB.


i also get the following error reported after every startup which i have been getting for a long time and have not thought may be connected to issue:


---Application terminated: MPTT has been denied the "Cross Application Communication" permission---


i will next run through the OS load procedure no having success with safe mode.


Any additional insight would be most welcomed.
