New ROM gives Optimus G users a taste of official Jelly Bean

If CyanogenMOD isn’t your thing, a new ROM based on the shipping Jelly Bean ROM for the international LG Optimus G E975 is available, and it’s very, very fast.

Unlike CyanogenMOD 10.1, which is a bit hacky and removes NFC and capacitive button support, the new ROM is LG-built and sanctioned. That means it closely resembles the finished product we’ll see in Q2 when Rogers, Bell and TELUS push their respective updates to devices. It’s based on Android 4.1.2, so it isn’t quite as new as CM10.1, but having everything working is a nice change of pace.

I installed the ROM onto my Rogers Optimus G and found that LTE on the 2600Mhz band worked perfectly. The company has expanded its QSlide apps feature and has integrated Google Now and expandable notifications, but otherwise the software looks unchanged.

What has been changed is the speed; the ICS ROM was never slow, but on Jelly Bean the Optimus G shines. We’ll bring you a review of the ROM when it hits Canadian devices officially, but if you have the know-how to dive into the guts of your phone, take a look at this one.

If you haven’t checked out our initial review of the LG Optimus G, give it a read, too.

    Now THAT is how you appease the power users.

    What 4.1 gives, 4.2 shall take back.

    4.2 isnt THAT buttery, IMHO

    I’ve been following the ROM for a while now and it sounds like there are still a bit of bugs to work out. I dunno… Still running ICS right now because I’m too scared to upgrade to JB, even though I’ve flashed tons of custom ROMs with the Samsung Galaxy S and Galaxy S2.

      The bugs are mostly with CM10.1 (and also present in stock 4.2, i.e. Bluetooth bugs).

      I wouldn’t be afraid to grab CM10.0 stable (based on 4.1). That has never given me any issues. I would hold off on any 4.2-based ROM for the time being though.

    I’m currently on the International version of the ROM and I have to say that I am extremely impressed, with both the developers and LG. It is super smooth and the International version at least for me is bug free. It doesn’t have the common bugs that version2 of the ROM had with WiFi passwords not saving and whatnot. Experienced flashers, give it a whirl and you will not be disappointed.

    Anything similar to this for Samsung Galaxy S II X?

  • Kezghan

    Using this rom the first version right now, other then the wifi password not sticking its an exceptional rom. Makes my LG E971 a much nicer phone to use. Better battery life as well.

    Are you sure it was LG that built it? I know they sanction it (even sending free devices to legendary developer Ricardo Cerqueira) but I’m pretty sure that credit should be going to the CM team, especially Ricardo.

    This ported E975 JB ROM from LG is worth a try. De-bloated of carriers custom software is a plus! Those are two big reasons to go ahead and root! Knowing LG, this version is as good as it’s going to get whether for this market or not.

    Hey guys, Id like to see a direct comparison of Jellybean Optimus G vs ICS Optimus G vs Nexus 4… to evaluate the software differences LGs new update is going to/is making.. and how it compares to the stock ROM.. (Ive heard I think, that the Optimus G w/ Jellybean is faster and less draining on the battery than the NExus 4, and it would be really interesting to see what an in-depth analysis will reveal.
