Android Central forums member ItsAllAndroid brings up some really good questions -- which root method (temporary or permanent) is easier, and what are the advantages of permanently rooting your phone? For some of us, the obvious answer is to perma-root and go, but not everyone is comfortable with the methods, or potentially canceling the warranty on their $500.00 Android phone. Let's take a look at each method, and maybe it will help you make your decision, after the break.
We're always talking about root, and probably confusing the daylights out of many of you guys and gals when we toss it around like everyone knows exactly what it is. If this describes you (and there is no shame in not knowing), we have a pretty nice resource you need to read. Have a look at it here, then come on back. We'll wait, :)
So now, hopefully you have a better idea of exactly what we mean when we say "root your phone." But if you still don't, that's OK, too. There's a lot of questions that could be asked, and the Android Central forums are full of helpful members and Advisers, ready to discuss. So hit them up until you're comfortable with the idea of rooting.
These are usually one-step apps that you install on your phone, and they give you root access until the next time your phone is restarted. They are a great way to get your feet wet,and you can do a lot with them -- both good and bad. The ease of use makes temporary rooting pretty popular, and it's a fine choice if your reasons for rooting are to use root-enabled apps from the Market.
That being said, some apps just aren't going to work unless you go all out and permanently root your phone. This depends a lot on which phone you're using, as manufacturers have an endless supply of dirty tricks to keep the hardware you paid for under lock and key. You'll either have to ask users with the same model as you're using, or use trial and error. The good news is that the popular root-enabled apps, and the ones you're most likely to want to use should work without a problem. Titanium Backup, Wireless Tether, Root Explorer and the like should do just fine.
The last thing to keep in mind, is that not all changes will be permanent. For example -- using a utility to "freeze" bloatware (applications from your carrier that you don't want or need) may not keep them frozen and hidden after a reboot. Also some of the newer HTC phones have
an evil little bug a feature that reverts any changes you have made to the system, bringing it back to the way it was before you started hacking away at it. In those cases, the only fix is to perma-root your phone.
This is where things get a bit hairy. Some phones, like the Nexus One, don't need to be rooted -- they can be unlocked via the Android SDK and modified at will. Other phones, like the OG Droid, are really easy to root, and will only take a few minutes. Finally, some phones, like the T-Mobile MyTouch 4G force you to jump through flaming hoops and follow often cryptic instructions, laden with warnings about bricking your phone. That's a whole 'nother rant for a different venue, but it does need said so that you know what you may be getting yourself into. You'll need to do your homework, ask any questions you feel are unanswered or are unsure of, and weigh all this into your decision. Everyone who says "It's easy!" (including me) really means they found it easy -- that doesn't necessarily mean you will.
Now that I've sufficiently scared you, it's time to talk about why anyone in their right mind would go through this. Besides the advantages of keeping changes persistent between reboots, and those few Market apps that won't work with a temp-rooted phone, you have what many consider the best part of owning an Android phone -- custom ROMs.
To flash any custom recovery, kernel, or ROM, you're going to need to have permanent root access to your phone. Flashing new firmware is very low level stuff, and you need read and write access to everything. The good news is that usually the rooting is the most difficult part, and a custom recovery gives you access to a tool that can take a snapshot of your system, and save it as a restore point. That's a good thing, because once you start flashing, you're hooked -- and a single command restore is priceless.
Hopefully I've helped a little in your decision making, and remember -- there is always help in the Android Central forums. Find the specific area for your model of Android phone, and look for the link at the top to the hacking section. Those guys live for this stuff, and will steer you in the right direction.
