Android 4.1 Jelly Bean for Optimus One Sets: P500, P505, P506 and P509

Its quite surprising just how many custom Android 4.1 Jelly Bean ROMs are coming out for old devices like the LG Optimus GT540 or the Optimus One. The Optimus One, which saw the release of a Jelly Bean ROM a few days ago, has now received another custom Jelly Bean ROM.

XDA Senior Member Rashed97 has released an unofficial CM10 (CyanogenMod 10) ROM for the entire family of the Optimus One, which includes the P500, P505, P506 and P509 (Optimus One, LG Phoenix, LG Thrive and T-Mobile Optimus One) variants. CM10 brings Jelly Bean with features such as a smooth interface, advanced voice recognition, improved and actionable notifications, along with CyanogenMod’s customization features and fast performance.

The ROM is currently a work in progress, and the following things work/do not work currently (quoted from the developer):

What works:

  • Wifi
  • Bluetooth
  • 3G
  • Display (obviously )
  • All accelometers
  • Google Apps
  • Most Project Butter related enhancements
  • All native apps
  • All Audio
  • Airplane Mode

What doesn’t work (yet as of 8/5)

  • Camera
  • Google Now Voice (will have to expand the /system partition to fix )
  • Screen on/off animation
  • Probably a lot of little things I haven’t noticed yet

What kinda works (yet as of 8/5)

  • Holo lockscreen animation (lags a bit or doesn’t show at all)
  • Lots of graphics related things lag

Let’s take a look at how the unofficial CM10 ROM can be installed on the Optimus One P500/P506/P505/P509.

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Make sure you have ClockworkMod recovery installed on your phone.
  3. Download the latest version of the ROM from its development page for your device according to its model number.

    In recovery, use volume keys to scroll up and down between options and power key to select an option.
  7. Perform a Nandroid Backup of your existing ROM, so that you can always restore it from recovery if something does not work out with this ROM. To perform a backup, select Backup and Restore –> On the next screen, select Backup again. Go back to main recovery menu after backup is complete.
  8. Select wipe data/factory reset, then select Yes on next screen to confirm. Wait a while till the data wipe is complete.
  9. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the ROM file on the SD card and select it. Confirm installation by selecting Yes – Install _____.zip on the next screen. The ROM will start installing.
  10. After ROM installation completes, select choose zip from sdcard again, then select the gapps-jb-medium-20120726-signed.zip file to install the Google apps package.
  11. After the Gapps package finishes installing, select go back then select reboot system now to reboot the phone to boot up into CM10.
    NOTE: To go back to your previous ROM, boot into recovery, select backup and restore then restore your previous ROM by selecting it from the list.

  • Duffmann116

    So i got this running on my p 509 using the 506 rom because it uses a gsm card as well. It works fine until i lock the screen. After it locks the screen stays black when i try to turn it back on. I dont know if anyone else has this same problem or if ”
    Screen on/off animation” is the same situation. Its a cool rom other than that.
