Rooting the LG Optimus M

I convinced my wife to let me root her LG Optimus M (stock Android 2.2.1). After the struggle I had to go through to root my 2.2.2 Ascend, rooting the Optimus was a breeze! Here's what I did:

• Turn on the following phone settings under "Applications": Unknown sources, USB debugging (under Development).
• From your computer, search for Gingerbreak and download APK v1.2; here's a Gingerbreak link that currently works.
• Connect your phone to your computer; on your phone, pull down the top menu, touch the "USB storage" message and turn on USB storage.
• You should see notification on your computer that your phone's SD card has been mounted. Copy the Gingerbread APK to somewhere on your phone (e.g. the "downloads" directory).
• On your phone, install the ES File Explorer (or your favorite file explorer/browser) app via Market
• Open the file explorer, find the Gingerbreak APK and install it (make sure "USB debugging" and "Unknown sources" settings are turned on)
• Run Gingerbreak, touch the option to root your phone. Your phone should reboot by itself in a few minutes. If it doesn't reboot by itself, Gingerbreak probably didn't work. After the phone reboots, you should see a "Superuser" app in your list of apps.
• Install Titanium Backup (free version is fine) from Market.
• In Titanium Backup, touch "Backup/Restore", select an app you want to remove, then select "Un-install". Be very careful about which apps you remove! Removing the wrong one can brick your phone. Here is a list of "safe" apps to remove for LG Optimus M.

Here are the apps I removed. I'd recommend that you stop Boingo WiFi before trying to remove it---I kept getting error messages after removing it and had to reboot the phone before I could continue. Also note that some of these apps provide basic functionality; if you ever think you'll use that functionality or aren't sure, don't remove that app.

• Boingo wifi (had to reboot after removing)
• Gameloft free games
• Loopt
• Mail@metro
• Metro backup
• Metro 411
• Metro navigator
• Metropcs easy wifi
• Mocospace
• Myextras
• Pocket express
• Uno
• Virtual card
• Music
• Sns
• RSS reader
• Voice dialer
• Voice search
• Weather

Rooting the Huawei Ascend and Upgrading to Android 2.2.2 (Froyo)

Upgrading was the easy part. MetroPCS has a page of instructions on how to upgrade. I took the "Self Upgrade" option. Note that the actual download is from the Huawei Devices site. One thing I was a little confused about is that after you connect your phone to your computer, you must mount the SD card via your phone. I kept trying to run "mount" commands from my computer...

The hard part was obtaining root. First I tried z4root, the app that rooted Android 2.1 for me. No luck. After some searching, I learned about Gingerbreak. I tried v1.2, then v1.3, then v1.1. None of them worked. Argh! And now my battery is draining like crazy! I'm I relegated to a life of recharging my phone every day?!?! Lots of Google searching just turned up more and more references to z4root/gingerbreak. And, I couldn't seem to find anyone with my problem; until...

...I found this post. tokill88 was stuck in a similar situation... had recently upgraded to 2.2.2 and Gingerbreak wouldn't work for him. The thread was dead---3 months old. I registered and added my sad situation. I looked back a few minutes later and there was a reply from "Senior member" ShinySide suggesting SuperOneClick. Seriously? Could that be it? I had a little trouble downloading it and figuring out how it worked, but this video helped a lot. Note that I couldn't run SuperOneClick on XP, but it worked on Vista (yes, it requires Windows).

After rooting via SuperOneClick, I wasn't sure whether I actually had root. I tried Titanium Backup, which is how I removed bloatware from Android 2.1. It couldn't get root. Huh? I found threads talking about this problem and how to fix, but TB didn't even have the same interface. Somewhat randomly, I tried setting TB to "Force System BusyBox". I then restarted via Menu->More->Reload Application. Viola! But, that wasn't all. TB couldn't find the applications I really wanted to remove, like MetroPCS Easy Wifi. This problem was easier to solve (but more expensive). Install Root Explorer via Market and delete everything in /cust/metropcs/us/app. Done!

Was the pain worth it? Yes. I feel like I have a new & improved phone. Everything is faster. Settings->Applications->Manage Applications is useful; it shows me all running applications, not just the ones I started and lets me "force stop" ones I don't want to be running. I still use Advanced Task Killer, but the "Manage Applications" gives me more control and "force stop" really works.

The one thing I don't like about Android 2.2.2 is that I can't control end button behavior. I used to be able to hit the "end call" button to put my phone to sleep. Now I have to hit the power button. Annoying, but I'll live.

P.S. In case you brick your phone, I bet this post would be useful.

P.P.S. This seems to be a good article on task killers. As noted, CPU is more precious than memory; killing and restarting an app uses precious CPU. So, if an app you don't use restarts itself every time you kill it, what you really need to do is root your phone and remove that rogue app.

Mapping Android Version Names to Numbers

I get confused about what Android release names map to what Android release versions. So, I created this post. I got the list of names from this post. I got some of the numbers from Google search; the last two are the obvious guesses. As you might expect, you can also find this information on Wikipedia

• 1.5: Cupcake
• 1.6: Donut
• 2.0/2.1: Eclair
• 2.2: FroYo
• 2.3: Gingerbread
• 3.x: Honeycomb
• 4.x: Ice Cream Sandwich
• 5.x: Jelly Bean (?)
• 6.x: Key Lime Pie (?)

Using Compass and GPS While Hiking

My wife and I hiked up West Tiger Mountain #2 and #3 today. #2 is an elevation of approximately 2700 feet. The most popular route is to take the West Tiger 3 Trail (WT3T) up to peak #3. But, we decided to do a loop, following the Tiger Mountain Trail (TMT) up to peak #2, over to peak #3 and then following the West Tiger 3 Trail to get back to the trailhead. Here is a nice map of the trails around where we hiked. Purple is the TMT; green is the WT3T. I printed out a guide with latitude/longitude and brief descriptions of intersection points and we drove to the Tradition Lake/Plateau Trailhead

The reason I'm telling you about this on a mobile blog is that the Compass app was extremely handy for the hike. I used it for (1) latitude/longitude to match with the guide, (2) compass to make sure we were headed in the correct direction, and (3) elevation to know how far up or down we still had to go. I'll definitely make sure my phone is fully charged for my next hike.

Another reason I'm glad I had the Compass app is that our planned hike was interrupted. Half-way up the mountain, we saw a sign telling us the TMT was closed ahead. It told us to use the K-3 trail (purple dashed line on the map) to access the peaks. The Compass helped me figure out where we were on the map I printed and how close we were to the planned trail. The K-3 turned out to be a great alternative as it took us up to the old Railroad Grade (black dashed line) which reconnected with the TMT. Fortunately for us, the trail signage was quite good, providing trail names, directions to peaks and even distances, occasionally.

I can see why most people stick to WT3T. The TMT was somewhat narrow, steep and overgrown, but it wound through some gorgeous parts of the park, including across two ravines via wooden bridges with streams below. We were pleasantly surprised to find many foxglove plants which we learned about in our daughter's Fancy Nancy books. In contrast, the WT3T has wide, well-defined trail and is never particularly steep. They even had stairs built for the one steep portion. In contrast, the TMT had a number of steep sections with switchbacks built to make it easier to climb. There were a few parts where it took leg strength to pull myself up. We never saw anything like that on the WT3T. We didn't see a single other hiker on TMT; we saw 20+ other hikers on WT3T. Of course, we started the TMT at 8:20am and started hiking down the WT3T around 11:30am. Overall, I like the TMT better as it seemed like an interesting hike versus the WT3T which was more like an exercise walk.

Huawei Ascend Android 2.2 Upgrade

Finally!  It's out.  Here's the official MetroPCS Android 2.2 Upgrade announcement.  But wait.  I've rooted my phone.  Is the upgrade compatible with a rooted phone?  I'm skeptical.  This post describing a bad experience with upgrading after rooting worries me.  'course, it's possible this person wasn't super careful, or the Cricket upgrade is somewhat different from the MetroPCS upgrade.  Does anyone have experience trying to upgrade after rooting?  How did it go?  Which process did you follow: (1) using the App, (2) Self Upgrade, or (3) in-store Assisted?

I'm looking forward to the "Enhanced Processor Management".  Can't wait!

Rooting the Huawei Ascend

I just root-ed my Huawei Ascend. It was surprisingly easy. Tokenpoke at Android Forums provides an easy step-by-step guide to customizing the Ascend. I found it easiest to do everything from my phone. Here's a quick summary of what I did:

• Download the Skyfire browser from Market
• Use Google to search for ascend customization guide; click on the link without a page number.
• Download MetroStockRecover.7z and z4root.1.3.0.apk
• Follow Tokenpoke's instructions for rooting your phone and deleting apps.

I chose not to delete the Metro Web and Android Keyboard apps. I may delete the Metro Web app if I decide I like the Skyfire app better. But, AFAIK, I don't have a keyboard app other than the Android Keyboard and I don't want to be stuck without a keyboard! Is there a build-in keyboard that Android would use if I delete "Android Keyboard"?
As Tokenpoke notes, deleting Boingo and MetroWifi are probably the largest benefits since they will run in the background and you can't permanently shut them off (without rooting your phone). I'm already seeing benefits to rooting my phone and deleting apps. When I play Angry Birds, the animation is much less choppy. Also, interaction with the phone seems to be snappier.
Note that you delete applications from the "Titanium Backup" app. Click on an application, then click the "un-install" button. For reference, these are the apps I removed:

• Boingo wifi
• Loopt
• Mail@metro
• Metro backup
• Metro navigator
• Metro 411
• Metropcs easy wifi
• Mobile Im
• Mocospace
• Myextras
• Pocket express
• Swype
• Uno
• Voice dialer
• Virtual card
• YouTube

I didn't see the Google Skymap app.

Update 7/6/11: MetroPCS has released the Android 2.2 Upgrade.  If you've tried this on a rooted Ascend, please let me know by leaving a comment.  Thanks!

Daylight Savings Time

I got my wife an LG Optimus M when she decided to switch over to MetroPCS with me. Except for the slightly smaller screen size, it seems to be better than my Huawei Ascend especially with respect to responsiveness. The hardware specs aren't too different, so I'm guessing the difference is Android 2.2 (vs. Android 2.1).

There has been one serious disappointment, though. When Daylight Savings Time rolled around on Sunday, the LG Optimus M was still stuck in Standard Time. I checked Date and Time Settings, but there was no option for controlling the clock at all (not even whether the clock should be updated automatically or not). Fortunately, I found a thread on the DST issue where someone suggested rebooting and briefly pulling the battery when the phone is off. I'm not sure why I didn't think of that earlier. But, the good news is that it worked. Now the LG Optimus M is finally in DST. I wonder what the problem was. Did the phone receive a DST update, but it couldn't be applied until a reboot? Please comment if you know.
