Nexus 4 bootloader unlocking, rooting and installing a new ROM

Thu, 04 Apr 2013 00:17:00 +0100

I just got a Nexus 4 :)

Time to unlock the bootloader, install a new recovery, get root and install a new ROM.

Android SDK

Download the Android SDK from here and uncompress the zip file. I will be using the Linux version.

1mkdir ~/Android
2cd ~/Android
3unzip adt-bundle-linux-x86_64-20130219.zip

USB Debugging

In Android go to Settings>About>Build Number and click seven times to unlock the Developer Options. Then go to Settings>Developer Options and check USB Debugging.

Install atom422 in Galaxy Nexus

Sat, 16 Mar 2013 21:31:00 +0000

I’ve been using atom422 ROM with Ak Kernel for a week now, and I must say this is the best ROM/kernel combo I had in my Galaxy Nexus. And it’s underclocked!

I will be using atom422 v9 and Ak Kernel 731.

Backing up your device

Backup using Titanium Backup
Backup Nova Launcher settings
Backup SMS using SMS Backup & Restore
Reboot into recovery (I have ClockworkMod Recovery v6.0.2.3)
Backup (backup and restore > backup)
Go into “install zip from sdcard > choose zip from sdcard” just to guarantee that ClockworkMod Recovery is accessing the storage
Plug the phone into a computer (I’m using Ubuntu 12.10, and have already android-sdk)

Go into your android-sdk tools folder

1cd Android/android-sdk-linux_86/tools/

Go into adb shell and list the directories in your “sdcard” to decide what to backup
```
1sudo ./adb shell
2ls /data/media/0
3exit
```

Pull all the directories you want to backup

1sudo ./adb pull /data/media/0/examplefolder sdcard/examplefolder

The previous example will create a sdcard folder in your tools folder with the data folder pulled from your phone

Change the owner of the pulled folders

1sudo chown -R youruser:youruser sdcard

You can also backup using FTP for example. I normally use WellFTP Server.

Install Ak Kernel in Galaxy Nexus

Sun, 10 Mar 2013 22:06:00 +0000

I started using Ak Kernel after installing Xylon, as I talked about in my previous post.

I will show how to install Ak Kernel coming from another kernel an how to simply update Ak Kernel when a new version is released.

You can also read the kernel FAQ here.

Ak Kernel

Ak Kernel comes in two flavors:

Purity edition, the stable version
Cylon edition, a experimental branch

Install Ak Kernel coming from another kernel

If you are installing Ak Kernel for the first time in your ROM, follow this steps:

Install Xylon in Galaxy Nexus

Sat, 09 Mar 2013 22:43:00 +0000

I was having problems in AOKP, so I decided to try a different ROM and a different kernel.

I’ve decided to go with Xylon and Ak Kernel.

What is Xylon?

“A Generally based of many kinds of features around the Android Development and fits into minimal customization. It may act up like AOKP, but totally not at all. Overall, we’re still in work in progress state of changing the base to slightly minimal like FNV before. This ROM is built off with GCC 4.7, O3, Linaro Strings enabled. (Galaxy Nexus Kernel, fusion with anarkia’s horn, O3 and Linaro GCC 4.7.3 enabled.).” from xda-developers

Low RAM problems after AOKP Build 3 update

Sat, 23 Feb 2013 17:33:00 +0000

After updating AOKP to the latest build 3, my phone started to get really laggy. Digging around in Google I found others having the same problem.

It seems that the SystemUI has a memory leak, and starts consuming an abnormal quantity of RAM. This means that apps will start to be killed and relaunched, including the UI. The consequence is the sluggishness of the phone. Rebooting solves the problem, but it’s only temporary.

Updating AOKP in Galaxy Nexus

Mon, 11 Feb 2013 22:48:00 +0000

AOKP build 3 is out, and after showing how to install AOKP from scratch, this is how I usually upgrade a ROM in my Galaxy Nexus.

I only use this procedure between builds of the same ROM, and typically when the base Android version is the same (in this case 4.2.1).

Backing up your device

When upgrading I usually only backup with Titanium Backup and within ClockworkMod Recovery. Usually I don’t copy the backups to my desktop.

Reinstall Oxygen ROM in HTC Desire

Mon, 02 May 2011 21:12:00 +0100

I’m currently using the Android Oxygen ROM in my HTC Desire.

As the version 2.1 just came out, I’ve decided to wipe my device and do a fresh install. Also I took the chance to post the procedure.

Note: I have root on my device.

Backup before wipe

I used Titanium Backup to create a backup of my apps
I used SMS Backup to backup my sms to GMail
I backup up my sdcard using rsync in Ubuntu

1rsync -axS --delete /media/sdcard/ /media/backup

I’ve manually kept a list of all the apps I want to keep. I will installed them all by hand, as needed, and restore only a list of selected ones

Download ROM and prepare for installation

Download Oxygen ROM v2.1 from xda-developers forum
I’ve formated my sdcard (Settings > Storage > Erase SD card) so I’ll have a really clean install
Copy the ROM zip file to the sdcard

Reboot into Recovery and backup entire ROM

I have the Clockwork Recovery (installed via ROM Manager), so I rebooted into recovery by long pressing the power button and rebooting into recovery
In Clockwork Recovery interface:
- backup and restore > Backup
- reboot system now
After rebooting backup from sdcard (/media/sdcard/clockworkmod/backup/)

Reboot into Recovery and install

Reboot into Recovery
In Clockwork Recovery interface:
- install zip from sdcard > choose zip from sdcard > update-oxygen-2.1-signed.zip > Yes - Install update-oxygen-2.1-signed.zip
- press back button
- wipe data/factory reset > Yes – delete all user data
- advanced > Wipe Dalvik Cache > Yes - Wipe Dalvik Cache
- advanced > Wipe Battery Stats > Yes - Wipe Battery Stats (if your battery is 100% and charging)
- press back button
- reboot system now
