I have posted this a few places so sorry if this is a repeat from the Phoenix forum, but it has been hard to find good info on these phones so I'm making sure this is easy to find. This walk through assumes you are starting with a stock unaltered Phoenix/Thrive (Froyo 2.2.1) I have tested it on my Phoenix but it has not been tested on the Thrive so mileage may vary use at your own discretion. If you brick your phone its your fault not mine. After reading and searching I have found the easiest way to root the Phoenix, I am assuming it works the same with the Thrive. This rooting uses the Gingerbreak method which is pretty much a one button rooting solution. Any ways here is what you do. 1. First you will need to be able to load non-market APKs you have two options to do this. A) Update your phone to the latest version Froyo 2.2.2. B) Go to your dialer, type "3845#*505#[Phoenix]" or "3845#*506#[Thrive]" then scroll down to "Unknown Sources Test" and check the box (this one has not been confirmed by me so no promises) 2. Download the APK from the following link: http://forum.xda-developers.com/atta...1&d=1303829207 (I emailed the link to myself to make it so I didn't have to browse to it) Note* it i will yell about not knowing what to do with that kind of download but just ignore it and download it anyways 3. Use a file explore (I used ES file Explore) to search for the newly downloaded APK I'm sure someone out there knows exactly where it downloads to but I couldn't find it easily though I can tell you its on the SDcard. 4. Run the APK 5. Turn on USB Debug mode (Settings>Application>Development) 6. Go to your Apps and run Gingerbreak 7. Click the root button 8. Let the phone do its thing (it will reboot) 9. Reboot the phone manually to make sure the root took and you didn't end up with a temp root If all went well you have a fully rooted phone. Here is the link to the original XDA site I recommend reading it over (at least the first post) so you understand what is going on.
