Level Up - Android: How to Root Nexus 4 on Android Lollipop 5.0 (Easy)

In my last post, I explained how to flash Android Lollipop 5.0 system image to Nexus 4. After I did that to my own device, the next thing I did was root it, using fewer steps than that other post. ;)

Rooted Nexus 4 on Android Lollipop 5.0

This will be a quick walk-through for the steps I took to root my Nexus 4. These directions are extended from the site with the great "CF-Auto-Root" tool that we will use.

Prerequisites:

1. I assume that your bootloader is unlocked. If not, please see my previous post for how to unlock the bootloader.
2. I assume you have `adb` added to your environment variable PATH. If not, please see my previous post.
3. I assume you are running Windows, but Max and Linux users will be able to use these general directions also.

Walk-though for rooting the Nexus 4:

1. Download the LGE Nexus 4 Android 5.0 file from http://autoroot.chainfire.eu/#fastboot
2. Unzip the file. You should see two folders and three files in that folder, one should be called "root-windows.bat".
3. Connect your Nexus 4 device to computer, then run `adb reboot-bootloader` in your computer's terminal. This will bring your device to the "fastboot" mode.
4. Make sure again that your bootloader is unlocked before proceeding (label found at bottom-left).
5. Open your computer's terminal to where you downloaded and unzipped the file, and run `root-windows` (Mac and Linux users use your own variant). You should see a red Android if the process is working.

Congrats! When the script is done, it will reboot your device and your Nexus 4 will be rooted!

This process will install the Root Check app so that you can verify a successful root.

More info:

• I didn't have any trouble using these directions for rooting my Nexus 4, so if you have any troubles with the steps, then I'll try to help in my limited capacity.
• Previously, when I was running Android 4.4 rooted, I used ES File Explorer to browse the root directories. But, it didn't work in Android 5.0, so instead I am now using the Root Browser app successfully.

Level Up - Puzzles: Four Random Cards, Turn All Face-Up, Blindfolded (Solution)

Problem:
You have four cards placed in a 2x2 grid pattern. Each card is randomly placed either face up or face down. Your goal is to flip all the cards face-up. But, there are a few restrictions:

• You are blindfolded and never know which cards are face up or face down. Nor do you know how many cards are flipped either way.
• Your movements for flipping cards are limited. Each turn you can flip either one or two cards.
• You will only be told when all cards are face up. You will get no other notification on how the cards are orientated.

What are the fewest amount of turns required to ensure all four cards are (eventually) flipped face up? And how?


Ascii art on how the layout may look. Each card represents a card:

1 2
3 4

Sidenote: When this brain teaser was first told to me last week, the person explained the possible limited card movements as, roughly, "you can either flip the diagonal cards, a column of cards, or a row of cards. Or, you can flip just a single card.". I'm pretty sure the way I explained it ("each turn, you can only flip one or two cards") is the same and much easier to understand, so I guess that lowers the puzzle difficulty a little bit for you, the reader.


Solution:

Today's post will just be pictures of things that I haven't seen before. So, I'm sharing the knowledge:

Fun puzzle, full of roses, reminds me of my potato chip puzzle like this

Fun*2 jigsaw puzzle, full of the same candy cane, over and over

I've played 3 person chess before, but not a 4-way.

Just a big wine glass holding a lot of aerators. But, I guess I could call this a large decanter also.

Android 4.4 Developer

A few days ago, I had my Nexus 4's OS updated from Android 4.3 to Android 4.4. The system is running very smooth. Two of the first things I did was enable developer mode and then enabled all apps to use the new ART compiler rather than the old Dalvik compiler.

You are now a developer! Again!
