    Hi, everything worked for me, except the last 2nd step

    Now choose “Install ZIP from SD card” and choose the “CyanBook_JB_Beta1.zip”. Let it install.


    installation started after some time

    installation aborted with error

    “symlink: some symlinks failed
    E: Erroe in /sdcard/cyanbook_JB_V2.zip
    (Status 7)
    Installation aborted”

    pls help me on this error message.

    • That’s weird. Because It installed perfectly for me. Please download it again and try.

      • prakash

        Hi Ujjwal,

        Thank you for reply,

        The downloaded zip file is corrupt

        “CRC failed in systemliblibvorbisidec.so. The file is corrupt”

        • That is why I asked you to download again. Have fun.

          • prakash

            Hi Ujjwal,

            I download the file once again(3rd time) still the zip file is corrupt,

            can you download the file by yourself & try to extract the zip file to the folder & confirm me back, if it worked for you.

          • Downloaded and its ok for me. Please check your internet connection.

          • prakash

            ok, i think my internet connection is slow(64Mbps) 🙂

            1 help, can you download this file & re-upload in Mediafire & share me the link( new link)

          • What ISP in India is giving you 64 MBPS?! I still think its your ISP because my 3 MBPS connection downloaded it without any difficulty.

          • prakash

            sorry man if i had hurt you,

            I’m working in MNC company it has 400Mbpsx2, but i get 64Mbps speed,

            for you info ISP is Airtel & Tata & Reliance.

            do not bring my India & I don’t know why you are going out of topic,

            if u do not know about India pls do not talk about India,

            India has very thing, but nobody know it.

          • Great. Anyways, just download it again. The ZIP is healthy.

  • Siva

    Now in this version all the bugs are fixed or srill any bugs and crashes are present ?

  • Sudhir

    cyanogenmod has released the stable version of JB, but i am not able to understand with one to download and can you please help on this.

    Hi! I installed Android 4.1 JellyBean on my funbook and it worket fine for me. But I have some problems. Tata Photon Plus Dongle is not working and every time I tap on Status in About Tablet, it stops working! Please help me. Thanks

  • The amount of RAM shown is usable by other apps and the rest of it by Android System.

  • Looks like its not worth upgrading to this ROM

    • I’m using this as my b primary ROM. Rest is up to you.
