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…
- 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.
- 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)
- Unzip OmapClock & OmapClockPlus Manual Installation.zip
- Unzip OmapClockPlus_Wm_Smartphone.zip
- 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.
- 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.
- Copy the OmapClock.lnk file to the Startup folder on your Blackjack. (e.g. \Windows\Startup)
- 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)
- Launch OmapClockPlus (e.g. Start > Applications > OmapClockPlus) and click “Register” once OmapClockPlus opens.
- 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!

Please, Help me! A have a BlackJack phone. I am now in Ukraine, the Europe, I have unblocked my BlackJack phone under this card GSM, phone works normally. But I cannot use the Internet as in phone the password of an input in a network is blocked. How it is possible to unblock the password? Problem in that at input of structure GPRS it is impossible to keep the password of the new operator.

Just wanted to let you know, I just followed your instructions for my BlackJack running the WM6 beta, and it all worked to perfection. Program load time doesn’t seem to be much improved, but scrolling using the scroll wheel is much faster. Thanks for putting it all together.

I having alittle trouble getting this to load up on my blackjack. I cant really figure out how to get the file (setup XML) to go on my phone using Windows Mobile Device Center. So I’ve just been clicking and draging the file into my documents but when I open Security Configuration Manager it is still telling me I have a two tier setup. Any help would be greatly apperciated.

I happy to have found this site, I already unlocked my Blackjack, now i’m in the process of installing OmapClock.ink file to The phones windows\Startup menu, how do I do that. I cannot open or view the Windows file on my desktop. HELP!!!!!!!

For those that can’t find the Windows Folder, are you by chance navigating your files via ‘My Documents’ from the My Stuff link in your Start menu? For some reason, someone made the grand decision to only let you view certain file types using the My Stuff file manager. If that is the case then to get the cab file go: Start > Applications > File Explorer. All you need to do is hit “Up” and you should see the Windows folder near the bottom of the folder list. Let me know if this was helpful.

There is only 1 file in the OmapClockPlus_Wm_Smartphone.zip file. Can you clarify?
