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
cd Android/android-sdk-linux_86/tools/
- Go into adb shell and list the directories in your “sdcard” to decide what to backup
sudo ./adb shell ls /data/media/0 exit
- Pull all the directories you want to backup
sudo ./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
sudo chown -R youruser:youruser sdcard
You can also backup using FTP for example. I normally use WellFTP Server.
Don’t forget to backup at least your “clockwork” and “TitaniumBackup” folders!
Note: clockwork backups are located in “/data/media/clockworkmod” and not in “/data/media/0/clockworkmod”, at least at my system.
Check in what folder you have the following folders: “backup” and “blobs”. That will be the correct clockwork backup folder.
Wiping your device
- Format /data and /cache (wipe data/factory reset)
- Format /system (mounts and storage > format /system)
- Format /sdcard (mounts and storage > format /sdcard)
- Wipe Dalvik Cache (advanced > wipe dalvik cache)
After these steps, your device, including the “sdcard” is cleaned without ROM or files.
Installing atom422
I will be installing atom422 v9 (ATOM422_maguro_v9), based on Android 4.2.2, Google Apps (gapps-jb-20130301-signed), a productivity pack provided for this ROM (Email/exchange, thinkfree document software, video editor) and Ak Kernel Cylon edition, version 731.
- Create a new folder in your “sdcard”
sudo ./adb shell cd /data/media mkdir 0/0.ROOT/atom422 exit
- Push the ROM, Google Apps, productivity pack and the kernel into your phone
sudo ./adb push ~/ATOM422_maguro_v9.zip /data/media/0/0.ROOT/atom422 sudo ./adb push ~/gapps-jb-20130301-signed.zip /data/media/0/0.ROOT/atom422 sudo ./adb push ~/Productivity.zip /data/media/0/0.ROOT/atom422 sudo ./adb push ~/AK.731.CYLON.zip /data/media/0/0.ROOT/atom422
- Install the ROM (install zip from sdcard > choose zip from sdcard > 0 > 0.ROOT > atom422 > ATOM422_maguro_v9.zip)
- Install the Google Apps (install zip from sdcard > choose zip from sdcard > 0 > 0.ROOT > atom422 > gapps-jb-20130301-signed.zip)
- Install the productivity pack (install zip from sdcard > choose zip from sdcard > 0 > 0.ROOT > atom422 > Productivity.zip)
- Install the kernel (install zip from sdcard > choose zip from sdcard > 0 > 0.ROOT > atom422 > AK.731.CYLON.zip)
- Reboot (reboot system now)
Restoring your “sdcard”
- Reboot into Recovery
- Push your backed up folders into your “sdcard”
sudo ./adb push sdcard/examplefolder /data/media/0
- Reboot (reboot system now)
When restoring I tend to use WellFTP Server.
Restoring your apps
- Restore apps using Titanium Backup
- Restore Nova Launcher settings
- Restore SMS using SMS Backup & Restore
Ak Kernel settings
To change Ak Kernel setting use Trickster MOD Kernel Settings. Don’t forget to donate to the developer by purchasing the premium key.
I’m using the settings showed in this post by Nephilim. Yes, it’s underclocked but smooth as never before.
