Installing WhatsApp on Nexus 7

Nexus 7 doesn’t have GSM facility. So that means installing Whatsapp on N7 shouldn’t be possible. But in my experience despite of it giving warning it installs straightforwardly. Here’s my exprience on how I migrated WhatsApp from my phone to Nexus 7.
1. Install Whatsapp on N7 from market or through APK file. But don’t open the app yet.
2. Create backup of existing Whatsapp messages:
If you don’t want to migrate existing messages then you can skip this step. Of course, there is no reason why you should skip, since its pretty easy. Just transfer the file: “msgstore.db.crypt” from phone to tablet, which resides at “/sdcard/WhatsApp/Databases/”. And keep the file in the same folder in N7. Create the folder database if it doesn’t exist.

Using OTG cable to access external storage and 3G dongle on Nexus 7

In my last posts, I wrote about how to root your Nexus 7 and install Ubuntu Touch. Today I am going to write about how to use an OTG cable to access pen drives and External Hard drives. Also one of the most awesome thing you can do is to use 3G dongle on the Nexus 7. And I am doing it in questionnaire style.
Why use OTG cable?
You can use an OTG cable to attach following devices to your Nexus 7:
1. Pen drives
2. Memory card readers
3. External Hard Drives
4. 3G Dongle
5. USB Mouse and Keyboard
What is an OTG cable looks like?

Yup, OTG cable is that small. Some other variants of OTG cable also comes with no wire. Refer this.

Can any OTG cable be used with Nexus 7?

Installing Ubuntu Touch on your rooted Nexus 7

If you haven’t rooted your Nexus 7 yet, you can follow my previous post and do that easily. This guide assumes you have connected your device with your PC and can use ADB to push commands over to your device. If this doesn’t make any sense, read my previous guide.
In this post I am about to write how can you easily install Ubuntu Touch on your Nexus 7. Before we do that, you can read this article on why shouldn’t install Ubuntu Touch: 4 Reasons Why You Shouldn’t Install Ubuntu Touch on Your Nexus | OMG! Ubuntu!
But since we are dual booting the Ubuntu with Android, the reasons stated above won’t matter!
1. Installing Custom Recovery (Flashing TWRP Multi ROM)
Using adb commands the next you need to do is to flash a version of TWRP recovery which is tweaked for MultiROM support. The file I downloaded was “TWRP_multirom_grouper_20131022.img” from here: [MOD][OCT 22] MultiROM v16a (fix SuperSU for secondary ROMs) – xda-developers, and used following command to flash it.
fastboot flash recovery d:\path-to-recovery\TWRP_multirom_grouper_20131022.img

Rooting Nexus 7 and Unlocking Bootloader

In my previous post I posted a few screenshots of my new Nexus 7 which I bought recently. In this post I am going to write about how you can unlock the bootloader of your Nexus 7. This process can be basically done in 5 steps.
Rooting the N7:
You can live your life with N7 without rooting it. But as one of the Android Commandments say: “Thou shalt not use thine nexus unrooted” I think you need to be awesome instead and do unlock it to get these features to work:
1. Ability to use an OTG cable to connect pen drives to the device, thereby overcoming the 16 GB (13 GB available actually) limitation.
2. Using a 3G dongle to let your device take advantage of 3G (which by default this device don’t have)
3. Take advantage of apps that only works when device is rooted, like Titanium Backup and Cache Cleaner
4. Flash custom ROM’s and/or Install Ubuntu Touch on your device (and be a part of an OS in the making!)
You can read this article that echoes my thoughts, until the part where he used a toolkit to root (I rooted the old fashioned adb way).
Here’s How to Root the Nexus 7 – But Should You? | Android.AppStorm
Anyway, so how actually you root N7?
You can use the most popular Nexus Rootkit to do all kinds of stuff to your N7 including Rooting, flashing zips etc, but if you are geek like me, here is how to do it manually (and its way easier than you think):

My Nexus 7

I bought Nexus 7, 16 GB, 2012 Wifi model from Flipkart a week ago. And I have to say, it is one of my most awesome investment that I ever did. I immediately started my research on rooting it so that I can unlock the true potential of this beast. Now I have installed Ubuntu Touch on N7 and its dual boot with Android. But I faced numerous challenges in doing so, due to lack of experience in this regard. I decided to document my research and finding so that other who may want to unlock the bootloader of N7 and want to flash Ubuntu Touch can do so easily.
I am going to post this guide in three part post. In this first part I am presenting unboxing video and some screenshots of the N7 running Jelly Bean.
