    hey I put this on my k1 with no issues. any idea if this will be made official?

  2. Jason Johnson said... August 12, 2012 at 1:08 AM

    and how often do u imagine it will be updated? I would like to donate to khanning for all his efforts

  3. Satwant Sarai said... August 12, 2012 at 1:23 PM

    Hey Jason;

    From what Krook1 posted on XDA, updates will happen ones a week. I found a link to donate to Khanning and put that up of end of the post above.

    To answer your question if this will be made official?

    If you are referring to if this will become official release from CyanogenMod Team, to my best guess is this will not be a official CyanogenMod release, since this is not supported by that team, this was put together by Khanning and Krook1 and properly will stay that way since its not one of supported devices CyanogenMod supports. But never the less, it has all the features that normally CM roms has backed into these unofficial ports, you will not missing anything, don't let the word Unofficial word fool you, its only there so people don't go to CyanogenMod Team asking for support, since they are not supporting it.

    I hope that answered you question.

  4. Jason Johnson said... August 13, 2012 at 11:36 AM

    Thanks for the comment Satwant, I appreciate your answering my questions. When do you suppose there will be a fully functioning version of this 4.1 release? Sucn as, autobrightness, USB Mass Storage Mode, Incompatible Apps in Play Store, etc..?

    How can I go about getting the weekly updates (does it require me to re-flash everything on a weekly basis or is it a simple upgrade through ROM manager for example)?

    Also, thanks for the donation via paypal link. I would like to support the devs who make this all happen.

  5. Satwant Sarai said... August 13, 2012 at 11:51 AM

    Jason;

    I can not really say when all these issues will be fixed, but with each update it will be one step closer to being more polished. I think ones Khanning start putting his full effort into Jelly Bean (4.1) version for Lenovo K1 and with Krook1 work with this one, i think it will make things go faster. Khanning currently focused on getting Ice Cream Sandwich (4.04) stable before he moves onto to Jelly Bean.

    For weekly updates:

    You can either check this post, because I usually keep it up to date to with most current version, you can check top of this post when this post was last updated (blue color.

    or

    Go to the Original post on xda, that link is provided in my post above. (Check this post for latest weekly updates: Click XDA to go to the link)


    The Update:
    For new updates, good news is that you will not loose any of your settings (home screen/ data/ account information) with each update. Bad news is it will require you to to boot into CMW recovery to perform the update and flash two files. I have updated my above post to reflect if you are only updating. (Option 1: Update).

  6. Jason Johnson said... August 13, 2012 at 2:22 PM

    you good sir are a badass

    thanks for the updates, looking forward to getting 4.1 updates now

  7. Jason Johnson said... August 21, 2012 at 8:58 AM

    Hey Satwant, just curious about this. I had to put the ICS rom back on my K1, and didn't get much chance to play with the JellyBean version. I want to put it back on there but I noticed "the bad" section...can you provide any updates on this?

    The BAD:
    1.) Paid apps - Whats wrong with paid apps?
    2.) USB in mass storage mode (this is not supported on JB)
    Auto brightness
    4.) Rotate lock switch - Does software switch still work?
    5.) Incompatible apps - Amazon mobile (perhaps I need a better signature)- What other apps have you expereinced not working? Any timeframe on getting them to work? Anything I can do to help this along?

    I am not a developer, but an very technically inclined. Is there anything I can do to volunteer my time to make this port successful?

  8. Satwant Sarai said... August 21, 2012 at 9:16 AM

    Jason,

    Since I do not have this tablet anymore, I sold it few months. All the Bad and Good I post is directly from original post from Krook1, I forgot to update my post of bads and goods, according to the latest Version 2 release.



    The BAD:
    1.) Paid apps - Whats wrong with paid apps?

    This was fixed in V2, sorry forgot to update that in my post.

    2.) USB in mass storage mode (this is not supported on JB)

    Internal and external was fixed in V2.


    3) Auto brightness

    According to Krook1 it is still a issue in V2.
    Do it work for you on your device?


    4.) Rotate lock switch - Does software switch still work?

    Software switch still should work. It's the hardware switch that does not.

    5.) Incompatible apps - Amazon mobile (perhaps I need a better signature)- What other apps have you expereinced not working? Any timeframe on getting them to work? Anything I can do to help this along?

    Apps that listed as Incompatible apps: Amazon Mobile, there might be others.
    Have you experienced this with any apps you use? If so, list them. I'll put them in my post for reference.

    I also posted another version of Jelly Bean Rom, this one by Khanning, and seems like it has less problems with incompatible apps. Check it out at the following link, leave feedback on that post.

    It works great. Unfortunately, does not 3G and that's a shame. And the USB Host function is also missing.

  11. Vishnu said... September 7, 2012 at 11:39 AM

    Hi,

    I tried to download "Nvflash Windows Drivers - md5sum: 9aa3a4814ca63366329d85a22ed01f64", I am getting "The file you requested was not found" Error.

    Is there any link availble to download the drivers?

  12. Satwant Sarai said... September 7, 2012 at 2:46 PM

    Yea, that link is dead. I tried to find the file on my PC and re upload it and i could not find it, but when i do i will update the link.

    But, the drivers you need are also in the K1_CM10_JB_Starter_v2 file as well, download it extract it and there should be a "drivers" folder in there. The reason why another link was provided for drivers, because some might have problems using the drivers included with the kit and for some it works. So give that a shot, and let me know how it goes.

  13. Vishnu said... September 8, 2012 at 4:40 AM

    @Satwant: :( Need help. Process is hanging half the way.

    1.Tried with "Drivers" folder drivers. USB drivers worked fine, but APX drivers were not working
    2. So Downloaded NVidia boot-recovery drivers from http://www.modaco.com/topic/335416-nvflash-setup-instructions-drivers-links-active/
    3. After that I was able to run Flash-win
    4. But the process is stopping at "Formatting Partition 12 UDA Please wait.. done

    - After that cursor is not moving
    I think, i have installed wrong APX drivers. Can you please help me to get correct drivers

  14. Vishnu said... September 8, 2012 at 6:26 AM

    @Satwant..Tried again. Able to install now.

    ROM from the below link working fine.

    http://androidrootaccess.blogspot.in/2012/08/romjbaosp-jelly-bean-411-for-lenovo.html

    I will leave feedback.
    Thanks alot.

  15. Satwant Sarai said... September 8, 2012 at 11:53 PM

    Vishnu;

    Re download the file. I got some files mixed up in the guide, i have updated with the new file.

    The new file is called:
    NVFlash starter v2.zip

    Extract it and should have the file:
    flash-win.bat inside.

    Let me know, how that works out for you.

  24. Ariel Damasco said... December 3, 2012 at 1:35 PM

  25. Nihanth Reddy said... December 4, 2012 at 11:39 AM

    I do get an error "E:\ can't mount /cache/recovery/......"
    I have tried getting into recovery mode after installing JB AOSP.
    If I install V_starter2 version of JB of Cyanmodgen, I am unable to select the "intall from SD card" option. Home/Power button doesn't work for me.
    Is there anyone that can help me with this issue.

  26. Satwant Sarai said... December 7, 2012 at 12:56 PM

    Nihanth;

    I need to know more information, so i can try to help you with this.

    Were you able to successfully run: Starter_v2 ?

    Ones you extract the contents of the Starter V2, you need to put the tablet in APX mode(instruction in the post above). And then double click the file flash-win.bat from the starter v2 you extracted.

    Let me know if you gotten this far

  31. Satwant Sarai said... June 1, 2013 at 12:23 PM

    Adobe stopped support for jellyy bean.
    But you can side load it, here is the link:

    http://download.macromedia.com/pub/flashplayer/installers/archive/android/11.1.115.58/install_flash_player_ics.apk

    Let me if that worked.
    Keep in mind that you might have to enable install from unknown sources. You can enable by going to settings and then security and check allow unknown sources.
