Everything You may need to install android 5.0.1

I'm writing this so that you all will not have to go through what I just experienced when trying to flash the android 5.0.1 OTA manual update. Here are some of the errors I've gotten out of and I will give you some tips to get fix these. I always seem to encounter issues that no one else has when flashing, so here we go.

Tip 1

1.)If you are trying to flash 5.0.1 (tip applies to any version) from the google website here: https://developers.google.com/android/nexus/images ....Make sure your computer can handle ".tgz" files. This took me a day and a half to figure out. If you try to download one of the files off this website without the proper software to do so you will simply get a ".tgz" file that you cannot extract the necessary files from.

*The solution is to download winrar from http://www.win-rar.com/predownload.html?&L=0 this website. Once you do and run it the ".tgz" file will become a folder (icon should look like stacked books) and you can proceed to actually follow the instructions on the page where you downloaded the file from. I learned this the hard way.

Tip 2

If you dont really understand how to us the "ADB" tools or "SDK" and everything related sounds like a foreign language to you then watch this video: http://highonandroid.com/android-ro...r-android-in-a-bootloop-with-no-os-using-adb/. It will explain how to copy files to your device while in bootloop. Pay special attention to the part about making sure your drivers are set up correctly. Drivers always get me when I installs. This knowledge will transfer over to downloading any rom or factory image in the future.

Here are the appropriate drivers for copying files while in recovery to the nexus 5:

Tip 3

The way I installed android 5.0.1 was:

1.)I downloaded the file from the google developer website that i pasted at the top

2.)I moved that file to a folder named "root" that i created on my desktop

*In this folder i have chainfire auto root http://autoroot.chainfire.eu/ in case i need to re-root my phone, I have the adb and fastboot.zip folders in my root folder as well.

3.)I moved the folder inside the FASTBOOT folder and extracted the file that i got from the developer website here. Once this is down there is another

3.)I extract the files here. After you extract there should be another folder called "image-hammerhead-lrx22c.zip." I copied those files to the fastboot folder as well so that they are outside of the zip file. I did not remove the zip file once I copied the insides to the outside. Right or wrong this is what I did.

4.)I used the Command prompt to navigate to this directory. Watch the how to copy files video to see how to navigate using the "cd" command

*basically i typed "cd desktop" which means change directory to the desktop. Then i did "cd root"....then "cd fastboot" ...YOUR PATH MAY BE DIFFERENT.

5.)Once i was here i could follow more of the instructions on the developer website. I could run that "flash-all.bat" command to begin flashing the 5.0.1. In order to run this command you literally type "flash-all.bat."

6.)After it finished it said,

archive does not contain 'boot.sig'

archive does not contain 'recovery.sig'

archive does not contain 'system.sig'

This was okay, what you dont want is falures. While 5.0.1 is being installed, if you notice it say failure in the place where everything else is saying "OKAY" you have a problem. One guy on that xda link said:

"Extract the zip.You will get another file..extract that...keep extracting all the files till you get system.img, recovery.img, boot.img, etc ..then boot into bootloader and Manually flash all the img files

fastboot flash boot boot.img

fastboot flash system system.img

fastboot flash recovery recovery.img"

You can type this into cmd and do each one by one and it may work.

7.)YOU MUST MAKE SURE TO EXTRACT THAT SECOND FOLDER inside the developer file! If you don't you will get failures because the program is looking for them. That's why manually installing them may work as well.

8.)IF YOU SEE THE ANDROID WITH NO LOADING BAR UNDERNEATH this does not mean that you are bricked. I thought it did and kept flashing 5.0.1 over and over and over again. Then i just waited a bit and my phone rebooted and i say the glorious dots rotating on my screen. I lived happily ever after.

9.)Once you are finished installing 5.0.1 you will loose root. Run that chainfire auto root program.You have to boot in to the bootloader screen...NOT RECOVERY...just the screen where you see the android and you can select "start" "recovery" etc. and open up that chainfire program and hit a key to start it. There are instructions on the actual program if you need help. If you are on the bootloader screen that i am talking about and you start the program it will "auto root" that is, automatically root your phone and thats that.

10.)Download root checker off the play store to see if you are actually rooted and have a blessed day. https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&hl=en

Let me know if you need further explanation. I'm no pro but I've failed in soooo many ways i probably could help ya out! Jesus loves you all!
