try this one http://forum.xda-developers.com/showpost.p...&postcount=8519
am running on this.. it is smooth and without lag.. you might want to follow his thread

personally, i've switched to cm7/r2 hboot. i do suggest you to change to that as well since it gives you a larger partition of internal memory. you can always flash the downgrade.img if you ever feel like going back to stock hboot.

regarding your qs, go to this link, http://forum.xda-developers.com/showpost.p...138&postcount=1
there's a download link for stock hboot. apparently, its for coolsensation v3. the latest version is v4, im not sure whether has coolexe come up with a flashable zip for the stock hboot users or not. you might want to ask around in his thread. 

Dah tua dan bosan dgn GB roms. (Bored of them. AND I can't solve the slow USB problem w/GB despite all the efforts)

Then you aren't searching hard enough.

Use this to S-OFF.

Look for Fastboot Commander and use that during Fastboot mode on your phone (The red mode) Which shows FASTBOOT USB something then on the Fastboot Commander (PC), place your Cm7 image, flash. Done, do not forget to reflash+wipe or you will get bootloop.

If encounter problems, SEARCH. If cannot find on XDA, look @ our first few pages. If it's not there, then only post.
TQ.

Cis, that's even easier !!!!!!!!!!!!!!!!!!!

Just follow the vid Step 4 and then
use what I said earlier about FastBoot.
Please note there's a particular step to install CM7 hboot.
You need to wipe and then flash a CM7 hboot supported ROM, run it once, go back to bootloader, fastboot mode, flash CM7 hboot, go to recovery, reflash the same ROM again, then it should work (maybe need to wipe before reflashing) I forgot the steps but tinker around, a mistake can cause bootloop btw so yeah, just undo and go back to default hboot should allow you to boot if you really stuck.
since your hboot is so old, you can use the older methods (like mine)
Um, my speed after increasing the something from 128kb to 2mb speed went to optimum (around 3.5MB/s on Froyo Sense) but on GB (any) my speed is 750kb/s and is unaffected by the app above .
That's how bloody slow it was.

Try other than F12, F11, F10 etc. Until you get a boot option to choose what drive to boot from.
More importantly is your Recovery, can you do anything with it? When you flash a new rom it shouldn't bother you that much since it will be different.

I'm using touch. I highly recommend it
