Overclocking the Blackjack

You can safely overclock your Samsung Blackjack up to 252 MHz.  The default processor speed for the Blackjack is 216 MHz. I haven’t heard of anyone having issues once they overclock the phone. I’ve had mine overclocked for weeks with no problems. I bumped mine to run at 240MHz and have seen very little impact on the battery life of my phone. Don’t just take my word for it Google It (Overclock Blackjack) and do your own research to make sure you are comfortable with this.

You may ask yourself… How can I overclock my Samsung Blackjack? Let me explain how…

  1. First and foremost you’ll need to unlock your phone. Read my earlier post on how to unlock your Blackjack. If you do not unlock your phone none of the following recommendations will work.
  2. Now that your phone is prepped for overclocking you’ll need to download a few applications. From the research I’ve done, there are a hundred ways to do this, but a developer by the name of Tom Gech has created a nifty little application to speed up the process and make overclocking your Blackjack a breeze. Tom created a program called OmapClockPlus which is a helper file for an application called OmapClock. OmapClock does the actual overclocking of your phone, here’s the readme file translated from Russian. You’ll need both these applications to set up continuous overclocking on your Blackjack. Go to this post on forum.xda-developers.com and download the following (2) files:
    • OmapClock & OmapClockPlus Manual Installation.zip (13.4 KB)
    • OmapClockPlus_Wm_Smartphone.zip (4.3 KB)
  3. Unzip OmapClock & OmapClockPlus Manual Installation.zip
  4. Unzip OmapClockPlus_Wm_Smartphone.zip
  5. Create an “OmapClock” folder in the “Program Files” folder on your Blackjack (e.g. \Program Files\OmapClock) and then copy the OmapClock.exe and OmapClockPlus.exe from the OmapClockPlus_Wm_Smartphone.zip file to this location.
  6. By default the overclock speed for this setup is 240MHz. If you want to increase the speed to 252MHz open the File: OmapClock.lnk with NotePad or some other text editor and change the “-clock 240″ to “-clock 252″ and hit save.
  7. Copy the OmapClock.lnk file to the Startup folder on your Blackjack. (e.g. \Windows\Startup)
  8. Download the following file by right click the following link and click “Save Target As…”. Download File: OmapClock Shortcuts.zip . Unzip and copy the two files to your Blackjack’s Start Menu folder. (e.g. \Windows\Start Menu\Applications)
  9. Launch OmapClockPlus (e.g. Start > Applications > OmapClockPlus) and click “Register” once OmapClockPlus opens.
  10. Exit & restart your Blackjack. That’s it! If you want to make sure everything took go to OmapClock (e.g.  Start > Applications > OmapClock) and it should say “Current Clock: 252 MHz”.

I hope find this helpful & happy overclocking!

Unlocking Your Blackjack

Before you can optimize and configure your Blackjack to run at optimal speeds you must first app unlock the thing. App unlocking means you can run unsigned 3rd party software on your Blackjack. If you don’t application unlock it’s security settings, any changes you make that is registry based, will not be saved.

NEW: Please note this not a SIM Card Unlock, this is an Application Unlock. Please read the post “Unlocking the Blackjack SIM Card” to learn how to do this.

Here is the easy steps:

  1. Download and install Device Security Manager Powertoy for Windows Mobile 5.0 from Microsoft. This is a nifty utility to show what security policy is in effect. If you connect your Blackjack to your PC, you’ll see two tier security policy is in effect.

  2. Download and copy secpolicies.cab to your Blackjack using ActiveSync. I got this from sems.org who got it from Telus support, after following a post on qusers.com.

  3. Run and install it. This allows you to install third party SSL Root Certs.

  4. If you run Device Security Manager Powertoy for Windows Mobile 5.0 now (it is listed in Start - Programs as “Security Configuration Manager”, you’ll see now you are using One Tier Prompt. Select Security Off and click Provision. It will install tool.cab to your device and then provision the settings.

These instructions are based on the ones found for the Motorola Q provided by sem.org.
