Samsung Galaxy Tablet Rooting (and Stuff)

Let's be serious - I've had the damn thing for months now.  Nothing left to do but root the device (and stuff).

Actually my decision was based upon rooting my original Droid, boredom, an app that flatly refused to uninstall, and the desire to break something beyond recognition.

I became an unwitting fan of Slacker when I discovered the Jeff Beck channel.  I became a detractor of Slacker when I noticed the application was always running for no practical reason I could divine.  No matter how many times I killed it, it came back like a good zombie (ten points for the gratuitous zombie reference).  So it had to go.

I tried uninstalling but Slacker was having none of this.   Don't ask me why but for the first time in my three year Android experience, an app claimed it was uninstalled and remained available.  I got so frustrated that I let this be the final shove toward rooting, as Android refused to let me simply delete the app from its directory.

Rooting, by the way, has come a long way from the days of my original Droid.  One was required to perform all sorts of technical and command line gymnastics to root back then.

Let me pause to say a nice word about the HTC Sensation 4G.  This little speed demon does whatever I want and quickly.  I can't come up with many reasons to root it.  I wish I could say a nice word about its provider, TMobile, but I can't think of one.  Eight years of solid service from Verizon and then my company switched to TMobile.  Arrrrrrrrrgh!

I looked around a bit for different sets of instructions on rooting and settled on this page.  There's no point in going through the minutae, as the site has step-by-step instructions.  The important prerequisites here are that the tablet is running Gingerbread and is the correct model (else you'll do Bad Things to it).  Updating from pre-Gingerbread is certainly doable but is beyond the scope of this entry.

You will need to download three files to accomplish this: Odin (sends file from pc to tablet), the correct Samsung USB drivers, and the rooting file.  Links are provided.

NOTE:  this procedure requires Windows.  While there's probably a way to do it with a real operating system (or a Mac), this was the path of least resistance for me.

You install the USB drivers, run Odin and point it to the root file, put your tablet into download mode (power and volume down buttons), then GO.  You'll know almost instantly whether it worked or not.

This method of rooting does not destroy data (but a good back up is always recommended).

NOW WHAT?


Now you can use all of the marketplace apps that require root.  Titanium backup is a long-time favorite which won't run without root (all programs I mention here are free from the market).  After you install, make sure to allow superuser permissions and tell it to remember this.

Here is where the real fun starts.  Titanium gives you an exhaustive list of everything on your tablet/phone.  It will allow you to back up each and every app and also to delete them.  Since I decided to fly blind for the most part, I made sure to back up everything I wanted to delete first.  The app will also allow you to schedule backups.  There are a few valuable features available in the paid version; you should check it out.

Because you are rooted, you have an awful lot of power.  In fact you have the power to completely mess up the device if you're not careful (so be careful, ok?).


Having said that, there are several ways to recover if you manage to brick your tablet.  Google is your friend but with the rooting comes Clockwork, which can back up and restore your device for just such emergencies (user generated or not).


Slacker uninstalled permanently, via deleting its files.  You could always browse the files but rooting allows you to modify and delete the important ones.  Try not to delete any really important ones, ok?  One of my greatest joys here, after Slacker, was deleting the social media garbage that accompanies most if not all devices.


To save you some time, here's a list of apps I deleted (remember: Tmobile provider, ymmv):


  • AllShare
  • Android Live Wallpapers
  • AngryGPS
  • ChocoEUKor
  • Pulse
  • Digital Frame
  • DRM Content
  • DRM Content Launcher
  • DRM Protected Content Storage
  • Feeds and Updates
  • Kobo
  • Live Wallpaper Picker
  • Maps
  • Mobile tracker
  • Mobile tracker settings
  • Music Visualization Wallpapers
  • News & Weather
  • Perso
  • Readers Hub
  • RoseEUKor
  • SNS 1.0  (social/Facebook)
  • SNSAccount (Facebook)
  • Social Hub
  • Talk
  • TwWallpaperChooser
  • Y! Finance Clock

Less fine print:  My idea here was to make the tablet a lean, fast machine, completely without crap I don't use.  The device will run fine without all of the above apps.  If you like blinky lights and flashy wallpapers, adjust your pruning accordingly.  While there are still a few apps I need to research, this is the great majority of them.  Again, Google is your friend (or better yet, Ixquick or Duck Duck Go, which don't track you).

If you're like me, you'll want to disable any of the tracking, GPS, or location-based features.  Yes, I know they're terribly neat and awful convenient, but they're not called tracking for fun.  And no, this won't stop a determined law-enforcement agency from warrantless spying, but it will make things that much more difficult for them.

After you're rooted you can also experiment with overclocking.  This is where you can make your device faster (or slower to save resources) with software.  I used an overclocking widget, available in the market, with my original Droid.  I installed it on the Galaxy but have to experiment a bit more with it before I can recommend it.  It had some nasty side-effects which may take it out of the running.  Research is best before overclocking anyway, so my screwups work for your benefit.  Then when you're done, you can overclock your home pc [insert evil laughter].

Go for it - you'll enjoy the power and freedom to set up your device the way you want it.  If you have any questions, ask!

Further Reviews of HTC Sensation and Samsung Galaxy Tablet

It's been a while since I got my grubby paws on the Samsung Galaxy 7" tablet, as well as the HTC Sensation 4g phone.  I wanted to update my impressions on the devices, just in case anybody's reading.

HTC Sensation 4g

My boss keeps telling us he will always have more G's than we do and to date it's been a factual statement.  I suspect this has more to do with our carrier being T-Mobile than anything else, but it's not like we have a control sample to test out this hypothesis.  Suffice it to say that the coverage was much better with Verizon, our previous carrier.

This phone has largely been a blast.  It's a speed demon that has required very little instruction or maintenance.

My favorite/most useful apps:

  • Opera Mobile - a fast browser
  • WiFi widget - to turn off/on wifi quickly
  • gStrings free - excellent, free guitar tuner
  • World Newspapers - great source of news, albeit a little unsteady
  • TV listings - for obvious reasons
  • Wolfgang's Vault - classic rock streaming
  • Slacker Radio - the Jeff Beck Channel... say no more.
  • ES File Explorer
  • ConnectBot - ssh
  • SysAid/PRTGdroid - work apps
  • AK Notepad - a yellow pad
  • Timeriffic - controls functions by time to extend battery

I could obviously do without the T-Mobile crapware but I have not rooted the device (yet).  I am waiting until others do to see if the gains are worth it.   I am very satisfied with the default messaging and email apps, which is a miracle in itself.

The battery life is so-so, but definitely better after applying Timeriffic.

Samsung Galaxy 7" Tab

I am very specific about this model because there is also a Samsung Galaxy phone and a Samsung Galaxy 10" tablet.  It makes ordering accessories a bitch sometimes.

Given the choice, I'd rather have a 10" tablet but I couldn't argue with the price of this one.  This is a completely different device one may think: in essence, it's a very large phone.  The technology is a little older and a bit slower than the Sensation.  While it doesn't have a phone, it has a phone number.  I guess I could make calls if I rooted, which I haven't.  It will message.

I will get around to rooting the tablet, if for no other reason than the operating system's willingness to allow any program to start itself for fun.  Task Killer has a busy job killing all of the self-starting programs.  These can be killed or frozen when the Samsung is rooted.


My favorite/most useful apps:

  • Advanced Task Killer
  • Xiaalive - radio streaming
  • Android Assistant - takes the place of many utility apps
  • 1Page BBC - BBC news
  • Drudge - Drudgereport.com viewer
  • Astro File Manager
  • Zeem Launcher - small, fast replacement for stock Droid launcher
  • PremierGuitar - guitar magazine reader
  • Scanner Radio - listen to radio scanners all over the world
  • Sparse rss - rss feed reader
  • Yahtz Me - Yahtzee clone for my wife
  • Angry Birds - my nephews would kill me if I didn't have this installed
  • CPU Usage Monitor - cpu graph

I like my tablet and will continue to use it.  It is just the right device for when I need to spend a little more time on a larger screen than on my cell phone.  I check my rss feeds in bed and this is a pretty good device for the task.

I noticed that charging seemed like a day-long affair.  My advice is to charge this only via the supplied charger, not the usb cable, as the supplied charger puts out twice the current and this is a rather large battery.  If you turn off wifi when not using it and can calm the apps down, the battery will last a while.


The thing that irks me the most about Android devices is the programs that start on their own.  There is simply no reason for it.  If I have disabled GPS, why does TeleNav start by itself?  If I don't get push mail, why does Mail start?

Samsung Galaxy Tablet Review

I have been playing with a few tablets lately, trying to figure out where they fit in my bag-o-tricks.  At work we got a Samsung Galaxy (7") and a Motorola Xoom (10"), both through Verizon, our carrier.  My boss gravitated to the Galaxy and me to the Xoom almost immediately.

I don't care how much of an old wives' tale it is, size matters.  Upon first glance, there was simply not enough screen real estate happening for me on the Galaxy.

Fast forward some time and a change of carrier (T-Mobile).  I am loving my HTG Sensation 4G.  The phone is full of features and a real speed demon.  Unfortunately 4G is nowhere near as easy to pick up as top speed on the Verizon network, but we were expecting this.

I also received a Samsung Galaxy.  I would have preferred the upcoming 10" model but that's not what I got.  The Galaxy is a 7" model and only does 3G.  I can summarize the review thusly: it's a very large Android Phone.

I am intimately familiar with Android, which is a good thing.  I had the first Droid, which I mostly liked.  With reference to the Galaxy being a large phone, the one really weird thing about it is that a few of the programs from the marketplace (it uses all the stock Android apps) are sized for cell phones and thus don't take up the entire screen.  I guess the programmers have to put in an option for a larger screen (don't ask me - I can't program), which wasn't available when the phones first came out.

The device came with all the expected goodies: headphones, charger, and the obligatory special cable that converts the Galaxy to regular old USB.  I hate proprietary cables.  When looking for accessories, remember that there is also a Galaxy phone, so don't get them confused.  Your first purchase should be one of the shell cases with a kickstand.  You might also want some screen protectors and a spare proprietary cable.

Very important to me is performance and the Galaxy performs decently.  This is a slightly older device so it does not perform as well as the Xoom or my Sensation dual-processor phone, which is a little disappointing.  The manufacturers also need to get their stuff together with button placement: the Sensation and Galaxy have the Android buttons in different orders at the bottom of the screen.

The  audio is decent, although it could be louder.   The screen is very nice and, as usual, rotates.  It is not too heavy, although it probably could be slimmer.  None of these are deal-breakers.

There are five default screens, which seems to be a good number.  You can obviously make all sorts of changes to wallpaper and appearance, as you could with any Android device.  Remember that live wallpapers eat processor and battery more than static wallpaper.

It plays nicely with linux, which the Xoom didn't.  Just plug in and the device asks whether you just want to charge or appear to be a storage device..  Nicely done.

The wife and internal kids went nuts over the game selection.  She recently got a Crackberry Torch [the first was bad out of the box and the second seems to be headed in that direction too].  Although she enjoys the Crackberry, she really seems to be an Android girl, preferring the selection and instantly understanding the controls.

MANDATORY PRIVACY ALERT:

Like any other cell phone, it has all of the regular privacy-eating features, like GPS tracking, credential-remembering, and general tracking.  Some people find this convenient: I do not.  Do not be fooled by requests to divulge your location for 911 purposes: you can be tracked quite well by cell tower triangulation as it stands.

APPS:

No matter how many Android devices I have, here are my favorite apps:

  • Timeriffic: set up profiles to control the device's functions by time of day and day of week - saves battery life by shutting off phone in the wee hours.
  • Scanner Radio: listen to police and fire scanners, locally and across the world
  • Xiia lite: listen to streaming radio stations
  • Wifi Widget: turn wifi on or off with one button
  • Opera: a great, fast browser
  • World News: read news and feeds from all over
  • Reason/Drudgereport/BBC News apps
  • gStrings Free: my favorite guitar tuner
  • Sparse RSS: no frills rss feed reader, imports .opml files from your main rss reader
  • AndFTP/AndVNC/ConnectBot: ftp, vnc and ssh connectivity tools, cross-platform
  • Maildroid: a decent email client which doesn't start by itself, like K-9.

 WELL?

The Galaxy 7" tablet is pretty cool.  As I mentioned before, it's just a very large cell phone.  What you can do with a very large cell phone is up to you.  I am experimenting with taking it to meetings for notes, although I prefer my Ubuntu-powered 12" netbook.  It definitely gets a lot of use at home, where the cell phone is too small and a laptop isn't handy.   You save a lot of time over devices that have to boot.  And everyone seems to love Angry Birds.

While I do like the tablet, I miss the Xoom's performance, OS, and extra screen real estate.  I do not miss the Xoom's not-ready-for-prime-time experience though...


Here's a minor niggle: every Android device I have used cannot tolerate recording at above voice levels.  Even acoustic guitar tends to distort the inputs.  I'd like to record my band but the sound is completely distorted.  As a coworker beamingly pointed out, his iDevice made a great sounding video - no distortion at all.
