Tips
Easily root Android phone by installing a program

Android Hacks
A blogger has publicized what he says is a “one-click” method for rooting an Android phone, including instructions and files necessary to do so. The author of RyeBrye.com has credited someone using the alias Zinx for a process to root a phone by installing an .apk file on an Android phone that roots the device without requiring additional steps.
The process is much simpler than previous rooting efforts: Install the flashrec.apk, click on Flash Cyanogen Recovery 1.4, and power off/on your phone to ensure that it worked. Just like that, you’ve got a rooted phone.
The danger of rooting a phone has previously been that novice users risked making a mistake that would permanently damage the phone. This decreases the chance of that happening, but Rye says that this process is STILL dangerous and makes no guarantee about whether or not your phone can be damaged.
RyeBrye is hosting the files and explaining the set-up process for a limited time. Read it thoroughly and make sure you know what you’re doing before attempting to root your phone.

Known issues:
* If your phone doesn’t work with cyanogen 1.4’s image (which I believe are 32A based HTC Dreams) you should probably not use this. If recovery fails to boot, you should be able to pull the battery and reboot into the normal phone and then open the recovery flasher app again and “restore” your backed up recovery.img – but no promises… This is all done at your own risk.
* The exploit used (CVE-2009-2692) in this hack is already patched. The kernel was patched upstream on August 11th, so it is likely that an update will be pushed out from T-mobile VERY quickly to help prevent malicious people from using this same exploit.
* Apologies in advance to anyone who has to work quickly and work hard to patch this exploit in the wild. (Although it should be noted that if you just shipped phones that weren’t neutered in the first place, it would save us all a lot of work and help us all be on the same team… but that’s a topic for another post.)Original links:

Has anyone tried this yet? Does it actually work?
Yes, I did this last night and can confirm that the unlocking process works. It takes a little more time setting up Apps2SD (basically, the only reason I did this) but it's not as difficult as previous methods. Here's the tutorial I used for the unlocking part: http://androidandme.com/2009/08/news/how-to-root-…
Andrew,
Do you know how to "unroot" after using this method? I deleted the backup of the recovery image made before flashing the cyannogen recovery image? Do you know if it is still possible to go legit even if I've deleted that recovery image?
Here's a tutorial explaining how to unroot: http://forum.xda-developers.com/showthread.php?t=…
man what phone do u have and do u know if it works with the galaxy
…and this method works for the Canadian Rogers HTC Dream? …
I'm really surprised that more effort hasn't been put into developing an open-source rooting system that works across multiple hardware platforms. It seems like everything that's out there is sort of hackish projects that aren't very well tested or documented … the sort of thing you wrote about here is how things should be (i.e. download + one-click = root).
