Check out more than 60 custom ROMs for LG Optimus Me P350 on Hack My Android Forums.

The Cosmic Experia ROM is one of the best ROMs for LG Optimus Me P350. I was not really satisfied with CyanogenMod 7.2 which did not have good battery life. Though Cosmic Experia is based on CyanogenMod 7.2, this one is much better than the stock CM 7.2 ROM, thanks to Venkat Kamesh.  You need not overclock the phone after this as you can set the frequency from the Settings of this ROM. Below is the tutorial to install Cosmic Experia ROM on LG Optimus Me p350. Before you proceed, let use see what works and what doesn’t. You wouldn’t be dissatisfied with this 😀

What Works?

Everything works well in this ROM. If you face any issues with WiFi, use this Kernel, thanks to vivekalady Venkat Kamesh has introduced some new fixes which include:


After you flash the ROM from the steps mentioned below, you can apply the new fixes by flashing this zip file from Recovery.

Bluetooth Media works with BTMono which can be downloaded from Android Market.

    Installing this rom now.

    Have been having a MAJOR problem with receiving SMS. Modders should take a looks at this flaw. Will see of the problem disappears with this new rom. Will keep you guys posted.

    I would actually hear my notification for new SMS. I could even read its preview in the notification bar, and a notification exists inside the notif drawer. But when I try to access the new SMS, it couldn;t be found anywhere. I’ve tried other SMS apps like GO SMS and Handcent, but the problem still exists. It seems the problem worsens even more with the stock Messaging app.

    Sir Lalit, have you encountered this problem before?

    (Sorry if my post kinda out of place,)

    • chris

      My current ROM is Cyanogenmod 7.2 btw.

    • No it’s not. You are free to ask whatever you want to.

      I haven’t faced any such issues yet. However, I recommend you to use the MIUI ROM which I felt is better than this one. I flashed it today and will be posting a tutorial soon. MIUI ROMS are excellent for the UI and design. Everything works fine with MIUI!

      Let me know what you would like to do 🙂

  • Chris

    Just installed the rom. But i gotta say I liked the cyanogenmod design better than this rom.

    I haven’t checked the SMS problem yet, but I found a few flaws:

    1. Go Contacts EX is not compatible. contacts dont appear in the list, even though contacts appear in the stock contacts app.

    2. Saved times in the stock alarm clock app exist as empty bars. It is there, but has no labels.

    3. Quick pressing of the search softkey for the custom app doesn’t work, but long pressing does.

    Will be updating you guys if I find anymore bugs.

    I will try that MIUI rom. Please post the tutorial as soon as possible. 🙂

    Thank you!

  • saqib

    hey Mr. lalit i have cyanogenmod 7.2 installed and it works awesome but i want to overclock my device and i think its common knowledge now that this phone is reaaaaly slow.. what would u say i should do i if i want to keep my wifi working properly and cant install setcpu cause im too young to own a crd card 😛 i tried no-frills and was able to get my device to 844 MHz and everything seemed stable until i realized everythimg i opnened would just close randomely.. apps, folders, sms

    • You do not need to overclock it on custom ROMs because you have an option to set the frequency. Just go to Settings>Cyanogenmod Settings>Performance>CPU Settings and set the frequency. Not all ROMs support 844MHz overclocking, perhaps it might be stable at 728MHz max. There are more than 60 custom ROMs for this device which can be found at our forums here
