Bold 9900 - Won't fully Boot - Stuck at 75% on the boot indicator bar

HI there,


My Bold 9900 will not fully boot up. I have tried several battery pulls including a battery pull where the 9900 was unpowered all night.


When I put the battery back in, close the cover, the Bold 9900 tries to boot up. There is an audio click (which I have never heard before) and then the Blackberry Boot Screen comes up and the indicator bar starts at zero and moves up to about 75% (by the return arrow key) and then stops and stays here. I have left if for 4 hours and it still stays in the same spot.


This all started when my 9900 ran out of battery life and shut itself off. After this I have never been able to boot up. During my several battery pulls I have left the device onnected to power during boot, thereby charging the battery. It seems to have enough power in the battery to do the boot process or the battery would switch off during boot. ANy ideas of what to do? I have also tried to reset it by holding the Back key during boot but that doesn't work either...


I am really frustrated. I am a blackberry fan and took a Bold 9900 over an iphone 4s Q2 of this year. I need a reliable phone for work but this does not cut it.


Thanks in advance to those out there who can kindly answer this post!

Hey krambro,

Welcome to the BlackBerry Support Community Forums.


Thanks for the question.


First thing I would suggest is to check to see if this a software or hardware related issue.  To determine this, I would suggest following the steps in this KB article to reload the device software via force detection: www.blackberry.com/btsc/KB10144


If the BlackBerry® Bold™ 9900 smartphone does load up after following the steps, then it was software related.  If you still experience the same issue, then it would be hardware related and you will need to speak with your network service provider for repair options.


Let me know if you have any more questions.

Hi and Welcome to the Community!

The simplest way is to, on a PC (you cannot do this on MAC):

1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below.

2) Uninstall, from your PC, any BB OS packages

3) Make sure you have the BB Desktop Software already installed

4) Download and install, to your PC, the BB OS package you desire:

  • http://us.blackberry.com/support/downloads/download_sites.jsp
  • 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.

5) 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

6a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.

6b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:

If, during the processes of 6a or 6b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.

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!
