ICS 4.0.4 LG3 UI Custom ROM for LG Optimus One P500

LG3 UI ICS ROM for LG Optimus One P500

We just posted about the Jelly bean themed ROM for LG Optimus One, but it isn’t fully stable – there are hardly any custom ROMs that are completely stable perhaps because they are developed by individuals and not the manufacturers. In that case, you may wish to revert back to a stable ICS ROM for your LG Optimus One and this post would be of great help if you wish to do that. The LG3 UI custom ROM is an Ice Cream Sandwich ROM for LG Optimus One P500 which is based on the previous releases of CM9 for this device.

Since this is a customROM, you may face some bugs. To know more about this ROM, read the intro and features posted by the developer on the original thread:

This is my very 1st ICS MOD and I themed it with the popular LG 3.0 similar UI for ICS, and also did some tweaking stuffs since ICS is not really comparable regarding on Gingerbread’s performance and smoothness for our beloved device, I tried hard to make it more smooth and similar to LG 3.0 basically as what I can gather for now and hopping to give more stuffs and improvements in the future.

That was a short intro about the ROM. The developer also posts answers to a few questions that you may have about this ROM:

Q: Why based it with PARANOID and not just CM9?

A: Ok may be you’ll wonder why I based it to PARANOIDANDROID, basically because of the feature per app density changer, I completely configured system and app density included with this ROM for the best result, and I had disabled the feature of PARANOIDANDROID which is tablet UI because I believe it wasn’t really meant for such small screen device, ONLY advance users can touch the configurations if you still want it, though you can switch easily because of my modification just enable tablet ui on paranoid settings and set system ui dpi to 120 under hybrid settings and you’ll get the right sized tablet ui.

Q: Where the HELL IS DSPMANAGER! UrGGhhh!?

A: Since I’m trying to make it look like LG 3.0 UI, I have to clean some icons that weren’t on the actual UI, DSPmanager is included and I just hide from the menus, To access it.. go to the music player, play some songs, press physical menu button, tap on Equalizer and there you go! DSPmanager!

Q: WTF! CAMERA Flickers!

A: Yes It does flick because of the auto Overclocking values I set, by default its 729Mhz at maximum So to resolved this issue, step down your max CPU frequency to 691Mhz below

Q: What about the annoying BUGS!?

A: All ICS bugs for our devices is present since I’m just using our great developers port, Well there also unique bugs only with this ROM, and thats Launcher random FC, but it loads again.. it just happens no big deal.

Q: This ROM is for those who?

A: Basically for an ICS lover users, who dont mind good video playback and uses their phone more often for basic use not more on gaming and benchmarking purposes.

  • dK

    Thanks lot. At last found the BEST rom for my lg optimus one p500. I have tested different roms like MIUI snap series, hephappy,oxygen tiny stream etc. But found ICS-LG3 UI based rom most suitable with all things working to high satisfaction. Only the camera is flickering a bit even if underclocked to 691mhz.
