Back to Stock and Unroot on Nexus 7

My Nexus 7 is more or less a development machine, and as part of my development process, I need to test a tool called Mobile Iron.  It's the security solution that our company used.  So installed it, and it refused to install secured apps because it detected that my Nexus 7 has been "compromised", probably because it's rooted.

So to continue my work on it, I need to unroot it.  BUt how?

I used my office machine Dell Dimension M6600 running dual boot (Windows 7 Enterprise edition and Windows 8 Pro).  But then both failed to run the Nexus Root Tool 1.7.1 .

Then I realized that I successfully used a Netbook Lenovo S12 running Windows 7 Pro with Nexus Root Tool.  So I yanked it out, and sure enough it worked.

And so I carryout the unroot process, which is actually pretty simply:

• Launch Nexus Root Toolkit 1.7.2
• Click [Backup] to backup your device
• Click [Flash Stock + Unroot]

During the process, I needed to follow whatever instruction that came up on screen, but never the less, at the end, I have an stock Nexus 7 device.

2 more video player apps out of my phone

I loaded some Chinese dance videos to my andorid phone.  Some are flv, while others are avi and on.  I tried to play them, and found MoboPlayer and mVideoPlayer failed to load some of the videos.  And for that, they will stay out of my device.  DICE Player, BSPlayer and MX Player are still going strong.  So ... great!

Just because I uninstall you doesn't mean I hate you

Here's yet another round of my massive android software uninstall from my Galaxy Nexus phone.  I have this crave to keep my Galaxy Nexus lean and mean for several reasons:

• It's not a high end phone, so having lots of background process can seriously slow it the phone down.
• I don't see myself upgrading to another phone soon.  I like my Galaxy Nexus and I found it do great enough job to assist my daily life.  
• The more apps I have, the more time the phone will spent on updating.

So these are the apps I uninstalled recently:

Musical Instrument:

• SPC Demo, Real Piano, RD4 Demo : these are new breed of apps that provides digital musical instrument with low latency.  Finally Android has potential to do what Garage Band did on iOS device.  But then, I already have an iPod Touch generation 5 with Garage Band and other great musical instrument apps.  I don't need some promising but inferior apps on Andorid.

Explorer

• File Expert, File Manager, Astro File Manager: they are .. fine, but just not as awesome as ES File Explorer.  I still keep FX (File Explorer) because it doesn't have ads to annoy me, and it has some cloud access capability.

Wall Paper

• Mario Live Wallpaper, PhotoWall:  Yeah they are cute for a while, but eventually I got tired of them.

Voip:

• Line, GrooVe IP Lite, Kakao Talk, Viber, Bobsled Calling: I mainly use Talkstone, and have GV Phone as my backup just in case.  That should be it.

Audiobook: 

• Music Folder Player Free: it could be a good app, but I don't have time to play with it yet.

Time to pay up for Android apps that I like

I have $20 Google credit that I need to spent before Sept 30, and that spanned me to start looking various Andorid apps and see if there's any of them worthy to pay for.

The first one is DoggCatcher.  I've been keep looking and looking, and still found DogCatcher the best podcast app on Andorid.  Worthy of my $2.99.

For local network browser, I have to say that the free ES File Explorer still beats the rest of them hands down.  Here's why I have problem with the others:

• FX+ : The + feature cost a few bucks, which is fine if it works.  But it doesn't.  Network connection takes like forever to complete.
• FileExpert: Tried the network feature, and just keep giving me "Cannot Open"
• File Manager: Same ultra long network connection problem.
• Astro File Manager: Got the error "DUP_NAME"

At the end, I settle with ES File Explorer.  Oddly enough, the product is free, and I don't know how to pay for it.

Next stop: Video player.  Once again, there are lot of apps, and I settled with a free one called Dice Player.  Don't know how to pay for it.

Then, audiobook player.  This one is odd, because I tried to pay for MortPlayerAudiobook, but then found Akimbo Player does a better job.  Both are free.

Next, VOIP.  I settled with Talkatone because it has both iOS and Android version.  And by paying US$9.99, I can ultimately get rid of ads on both the Android and iOS version.  Great feature, gotta say.  I also like GVPhone, but since I already paid for Talkstone, it doesn't make sense to pay for another one unless I found something that I really hate about it.

So there it is.  After researching for whole day, I ended up paying 2 apps.  Hopefully, I can find more apps that worthy to pay for.

Another thing I learned about Google Play: if you buy something, the among will be instantly credited from your account.  But if you cancel a transaction, it actually takes quite some time to credit the amount back.  At least I haven't seen it credited back to my Google Play credit yet.  Either that or the amount credited back to my another credit card.  This is so freaking confusing.

(Update) The refund finally comes back to my Google Play credit.
