Guide to Install Android 2.3.4 Gingerbread Custom ROM on LG Optimus One [Step by Step Instructions]
>> DON’T use the device much at the moment as you need to flash 3 more small but essential packs to power the custom Gingerbread ROM. Add-ons pack contains some default apps like Browser, Google Talk, Email, Music Player, FM radio, etc. which are not there in the market and are also not included with the custom ROMs.
To Flash Add-ons, connect the phone to computer and transfer the rest 3 zip files (File 2, 3 and 4) to SDcard that you downloaded before. Hold the power button and select Reboot, then choose “Recovery” from 3 listed options as shown:
Phone will now boot into Recovery mode. Select “install zip from sdcard > “choose zip from sdcard” and then choose the void- forever-addon.zip file to apply, select ‘Yes’ to confirm. Now reboot by selecting the ‘reboot system now’ option as done before.
Similarly, install the voidAddonsPack.zip file and after that the stock.zip file.
Note: Always remember to flash ONLY ONE zip file at a time (i.e. reboot between flashes). NEVER attempt to flash 2 zip files together without rebooting.
That’s it! You’re done with installing Android 2.3 on your Optimus One. Now you may want to customize the screen, add widgets, change themes, modify lockscreen & display and try those various brilliant tweaks listed under ‘CyanogenMod Settings’. Then sync or import contacts, download favourite apps, add media and photos to your SDcard that you backed up on your system. It’s a custom ROM, you can do anything. 🙂
