So I had a co-worker that got an EVO 4G.  Unfortunately he was still in a contract with the android hating carrier known as AT&T.  He wanted to see what he was missing all the while taking advantage of the 30 day return policy.  First thing he does once we get back to the office from the lunch time purchase was hand me the phone to root.  All I could offer at the time was wireless tether but I couldn’t pass up on the opportunity to hack away at another phone that I never touched before.  It was easy enough to root … Many have done so with the reflash app created by the awesome devs at unrevoked.com … If you’ve been to the site to download, you can see what 5 phones this rooting application applies to.

Needless to say, I had to unroot and bring his phone back to stock.  Understandably, he couldn’t keep up with 3 lines on AT&T and his own line on Sprint.  Searched as I may, I could not find a quick writeup on how to truly unroot (recovery partition and all) and bring back to stock.  This is what drove me to write one up myself.  If all you’ve done is ran the reflash app to gain root and change the recovery … then proceed with the following:

• Download the latest reflash untility from unrevoked.com
• Download the stock EVO recovery.img … The one I’m providing was extracted from the Supersonic_1.32.651.1_Radio_1.39.00.04.26_release_171253 RUU.
• Boot your phone into the recovery console and connect it to your computer.
• Mount the system partition
• adb shell
• rm /system/bin/su
• rm /system/app/Superuser.apk
• unmount the system partition, unplug your phone and reboot your phone back into the full OS.

• Start the reflash utility but make sure your phone is not plugged in.  It should give a status that its waiting for your device to be plugged in.
• Click on File and Custom Recovery.  Point it to the recovery.img file that I liked earlier.
• The bottom of the window should change from Clockwork Recovery to Custom.
• Now plug your phone in and let reflash do its magic.  Once its completed, congrats.

You will still need to manually uninstall your applications that take advantage of root like wifi tether or root explorer.

Here’s a fabulous app that I stumbled upon while sitting in California traffic this afternoon.  I play games … MMO’s, FPS’s, RTS’s … everything.  I’ve wondered if there was a ventrilo application for android phones.  So many times I wanted to listen in on how a raid was going or how someones 2v2′s were hashing out … Wanting to hear the guild douche scream that theres an aimbot on the server or just chatting with friends.

Well my friends we have such an app and its called Mangler.  Its surfaced back around when the moto droid launched and its still in its alpha release.  In my honest opinion, its a solid working beta to me.  The only issues I’ve seen is that I had a force close once after configuring to connect to my vent server … But after relaunching, it went right in.  Another issue is that it doesn’t like being navigated away from.  It will FC if you go to another app with it running.  It works in standby as you can put it an and bring it back out of standby w/o issues.  Other than that, it works great for my froyo’d moto droid running BB v0.4.
