Install Oxygen ROM [Ice Cream Sandwich ICS] on LG P500 Optimus One
Sometime back we talked about installing or flashing a Ice Cream Sandwich ICS ROM based on CynamogenMod 9 on LG P500 Optimus one. Today we will talk about another popular ROM called Oxygen which was available only for Gingerbread till now. But thanks to the Developer popdog123, an unofficial port of Oxygen ROM for Ice Cream Sandwich is now available and you can flash it on your LG P500 Optimus One.
Oxygen ROM is a highly optimized AOSP (Android Open Source Project) rom with only few added features and without any of not so useful features like “Theme Manager” or apps like FM Radio etc.
This Oxygen ROM is only supported on devices which are on New Baseband. If your device is on old baseband, you need to flash it to new baseband. (If you are not sure how to do this, ask me and I would gladly help you out).

The only file that is need for flashing this ROM on your optimus one is the ROM Zip file.

You need not to download the GoogleApps zip file seprately. The ROM zip file has already the Google Apps integrated inside it. This also saves you the trouble of flashing a seprate Google Apps using the Recovery.

OTA (Over The Air) Update app
One of the best things with this custom Oxygen ROM is integrated OTA (Over The Air) Update app which can help you update to a new version the moment a new update to the ROM is available. This means that you can install the new update without the need to download the new ROM zip manually and without using the recovery mode to flash it keeping intact all your data. This OTA app does everything automatically whenever a new update to the ROM becomes available.
