    I did all steps mencioned here, step by step, or from begin to the end. The diference that I saw is all pictures posted on this website is very very diferent from the phone, I do not why.

    I agree with Vortecduramax, Bara 93, tyler wewsecv, almost said the same thing, I just don’t know what is wrong with KING 3D ROM, even I cannot find out its official website. Now, my phone is broken ’cause of it. It does not power on anymore.

    I’ll send it to Lisbon, Portugal, to be repaired for free without any fee/charge/fare.

    I just wish much luck for who has it on phone and it runs normally, my best.

      First thing disable any Voodoo tools on your phone if any.

      Follow the steps carefully in page 2, if you miss single step it will not be updated.

      Thanks You!

      February 22, 2012 at 11:30 pm

      since its an official update which you tried to update with and it failed, you need to contact the LG Service centre for the same!

    This rom is not Ice cream sandwich – it’s theme!
    And this archive is broken!
    you can find KING_3D_ROM_v2.3 by KING4Developers.
    It’s the most recent ROM for LG 3d.

    I’ve followed all the instructions. My phone is rooted.
    When I run the install rom from SD card, the phone reboots, accesses the ICS rom and then give me:
    Can’t open /emmc/IceCREAMSandwich4.0_for_LGOptimus3D_KingROM.zip
    Installation aborted.

    I have downloaded the rom twice.
    The size of both are 277MB.

    If I try to unzip the rom on my PC it says unexpected end of archive.

    • NeaL Pradeep

    November 7, 2011 at 2:23 am

    nothing to do, neither with data+cache & dalvik clean ! :o(

    everything appear to be ok at restart (ok..ok..) then my phone reboot immediately (i think with an error): where can i find LOG file?

    • NeaL Pradeep

      November 7, 2011 at 2:29 pm

        What can i do ?

    • Andrea

      November 7, 2011 at 3:25 pm

      i try another time following the procedure : everything appear to go but after few second after my LG 3D “unzip” the ZIP file the phone reboot (i think with an error…)
      Can it depend from my “Vodafone” LG 3D (but with rooted + CWM) ?

      What can i do ?

      • NeaL Pradeep

        November 7, 2011 at 4:13 pm

          November 7, 2011 at 7:18 pm

          Ciao NeaL, you appear to be good informed : my LG 3D was Vodafone but i buy it unlocked (Now my network provider now is H3G (3 italia) : what can i do ?

          Its original firmware is really slow, is the worst i ever found…and doesn’t exist the famous very good MIUI for it : i think this is my only chance for now ! =:| :o)

          • NeaL Pradeep

            November 7, 2011 at 11:42 pm
