  • Cynagen

    Zip is corrupted, and don’t tell me to redownload cause I have a business connection with 0 issues with everything else on the web, so frankly this makes me weary of loading this up onto my phone. And I so want ICS damnit.

    • http://www.androidadvices.com/author/neal Pradeep Neela

      you can download the same again or from the source link below

  • IceMan_DX

    This is not the offical ICS OS Fools but a Rom !!!! Now your fucked over and cant even have the phone repaired under warrantie !!!!

  • Claudia

    OMG i just put it on my phone, n now it has random flashing boxes and i can’t click on anything, Can any one please help? thanks

  • Jordane Quissanga

    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.

    Hi, nothing..my LG 3D doesn’t install THIS ROM so yesterday evening i try to install the famous KING ROM 3D 2.2..and it’s OK !

    There is anyone that try this (and explain us if this started immediately or what to do) ?

  • isokpan efe

    how can I upgrade lg p970? or can I use this?

    • http://twitter.com/pradeepneela NeaL Pradeep

      no, p70 is a different model you cannot apply this procedure!

  • Andrea

    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?

    • http://twitter.com/pradeepneela NeaL Pradeep

      you cannot find the log file!

      • Andrea

        o no…shit ! So i can’t find where is the problem ! :(

        What can i do ?

    • Andrea

      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 ?

      • http://twitter.com/pradeepneela NeaL Pradeep

        its not recommended to update the n/w locked devices!

        • Andrea

          Ciao, mine is unlocked : my network provider now is H3G (3 italia)

        • Andrea

          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)

          • http://twitter.com/pradeepneela NeaL Pradeep

            you can apply this, let us know if you face any issues!
