Overclocking HTC Dream from 528Mhz to 614Mhz (Plus other tips of increasing device speed)

Requirements:
Rooted phone and custom ROM

My Device:
I am using

Once you have all that, all you have to do now is to modify the kernel of your device’s ROM it is running. To do that, download damien667’s boot image here: http://www.mediafire.com/?tzjgtdaydtz .

Copy the boot-OC.img to the root of your sdcard. Then issue these commands from the terminal emulator.

Code (type the following and press Enter after each line is inserted):

su
flash_image boot /sdcard/boot-OC.img
reboot

By now, your phone will reboot and voila. Test it out using Linpack or Benchmark Pi (free applications to test the speed of your device). It rocks.

At the moment, my Mflops (calculation using Linpack benchmark testing) is 4.2+ at the maximum. This is very far from what it used to be before any JIT and overclocking (at a paltry 2.2Mflops). The improvements have been seen and tested by utilising yxflash’s media player and playing DIVX unconverted at HD quality. It plays it at any resolution (as far as I tested). Of course at the higher resolutions the player drops some frames but everything is smooth with no stuttering or lags.

Using Gameboid now is very smooth, especially on games that were lagging a bit in the past, e.g. Alien Hominid.

Conclusion: Worth the effort to apply this. But as usual, do this only if you are familiar with your Android device (this guide is only for HTC Dream and not any other). This can work for the Magic, but you will need to do more research.

Repair Unallocated Space from USB Flash Drive

Often when you are into using some ‘special’ software that enables you to do fancy things on your desktop, your most trusty device is that USB Thumb Drive. With its huge storage capacity, no wonder people are using it as a boot device! Some of us might have used that to run Google OS or to load Operating Systems unto tiny Netbooks. The problem comes after we have written the image unto the Drive, only to find that there is no way to retrieve the unallocated space left by the written image. In my case, I was using the NetbookInstaller for Mac OS X, which only took 50MB out of the 3.75GB storage on my thumb drive. Naturally, right clicking on it would not allow you to recover anything (whether through ‘formatting’ or ‘property changes’). After struggling for some time, I found the answer:

0. Download the Lexar tool and extract to your PC – Click here to download: http://www.911cd.net/forums//index.php?s=386ac2de1215bfae9adb0d2fdadacd77&act=attach&type=post&id=369
1. On Windows 7, remember to right click and “Run as Admin”.
2. Select your thumb drive letter, and click on the ‘Non-Active’ radio button at the bottom of the window
3. Now click on the ‘Format’ button
4. Remove and insert back of your Flash drive
5. Go back to disc management and reformat the flash drive again and you will get the whole space again

Voila!

Thanks to Chrno for this tip:

“One problem though was BootIt crashing while formating even with admin [privileges]. Seems running it in compatibility mode for XP did the trick.”

You can do this by right-clicking BootIt and choosing “Properties” and going to the “Compatibility” tab, tick the box on “Compatibility mode” Run this program for: Windows XP…

Enjoy!

Journal on Sunday School Stories

The special thing about Sunday School (‘ss’ for short) is this: the teacher has the opportunity to present spiritual lessons at its most fundamental/basic form. There is no one single approach to it. Not everytime does it necessarily be evangelistic in format, though it should not be neglected. Some may focus on the ‘action’ of a passage. Some on the issues presented in a passage. Still others on relevance to the children itself. Well, a good balance is needed, not only for each ‘meal’ but the whole course too.

It is with these thoughts & prior experience in both receiving & teaching in ss that I am starting a journal, of sorts, to tackle some hard passages from the bible for a ss target audience. Too often, teachers rely only on set passages that are ‘easy’ & deemed ‘acceptable’ to children. I believe it is more often to do with the teacher’s desire & ability than anything else. Teaching children challenges mature Christians in conveying the gist of the spiritual lessons from the bible text. How do we make Revelation understandable to children? Too many shy away & find it too deep for children to understand. On some levels that is true, but on some others, not so. Excluding many bible passages because of the age level of the target audience waters down the fact that all spiritual lessons are applicable to all sinful human heart, and thus conveyable.

Will we shy away our children from the realities of the deceitfulness and destructive nature of sin? Thus I am starting each page of my ‘journal’ with short lessons from books of the bible that are usually deemed hard for children. As in all my dealings with children, there will also be accompanying art to help convey such things as necessary. This is more of an exercise which I hope will help family worship once my boy grows up to the age where he begins to understand words and thoughts.

I’ll try to snap a photo and post those that I think are interesting 🙂
