Greetings,

Me and krook1 have been working on a CM9 port for the Lenovo Ideapad K1. This is an Alpha release as there is still a lot of work to be done. I have included instructions to either flash as an update.zip with CWM recovery, or if your still on stock you can use the nvflash package.

I have very limited time to invest to this project so if anyone would like to help please join us at freenode IRC room #ideapad-k1. The source code download link is posted below.

Just installed this, running great.

Installed Apex Launcher (smooth and fast)

Tried Chrome browser, kept crashing

Physical home button doesn't do nothing (no big deal, low priority)

Can't seem to get it connected to pc via usb port.
Storage > USB computer connection > MTP is checked.

This is excellent news.. ! Great to see progress on K1 custom ROMs!

Even though i have flashed custom roms on other android devices, i am a nOOB when it comes to K1 -- ie, should the tablet be rooted first before one can flash this ROM ? (using Root methods mentioned on other threads here?) or just do what is mentioned here ? -- Sorry.., but inputs here will help a lot of us.

DISREGARD THE POST BELOW. BROWSER STILL CRASHES. BUT THIS ONE INSTALLS IF ANYOE WANTS TO PLAY AROUND WITH IT.


Chrome browser works. The problem is the same that all other unofficial ICS builds on other devices have. It has to do with the Device Id Check in the apk from the market. Download chrome from the link below and you are smooth sailing.

Like any Android device, flashing custom rom need custom recovery installed (ie CWM revovery).
And root is needed to install custom recovery !

I am not a NOOB, as I flash roms to my Droid Incredible all the time, but I have found the detail of instructions on flashing/root in the Idea K1 to be a bit confusing.

So any chance someone could add to the detail above, " if not rooted do install process #2 and follow these step by step"

Reads as if we can use the nvflash method, but no mention of rooting before, if that is the case great. I am looking forward to getting a new rom installed on my K1 as the stock is very buggy!

Sorry for not getting back to you sooner. The CWM update.zip is used if you have already used my Honeycomb rom with CWM included. If you are on stock, or unsure, just use the nvflash method. There are no requirements to using the nvflash method because it reformats all the partitions. (root is not required, and it doesn't matter what build you are coming from)

ok, thanks for your reply.

didn't know the nvflahs method; it works on all Android device ?

ps: I don't have K1 but Thinkpad. Is it because Thinkpad doesn't have his bootloader unlocked, so it's not possible to use nvflash ?

Great to hear, is there any special needs for nvflash or is everything included in the nvflash method. I seem to remember in one of the rooting methods reading about installing drivers or related software necessary to use nvflash.

That is exactly what I am trying to find out. I am planning on installing this when I get home in a few hours, but I am hoping that someone can add that detail to the post. I was looking a bit earlier, and found references to making sure you have these apx drivers installed for rooting etc, but no instructions.

Updated the nvflash section with the APX drivers and instructions.

Updated CWM recovery to 5.5.0.4 and fixed Backup/Restore. This will be incorporated into the next nvflash package. For now download the updated CWM recovery .zip in the 'Mods' section of the first post, and flash from recovery.

if you are not rooted and don't cwm on it already. Then just do the nvflash package instructions posted in the op.

    Posted a small update today. Alpha 1.5

    - Bluetooth fix (Audio doesn't work?)
    - Full market compatibility
    - Hardware buttons (Home, Back, Menu)
    - Rotation Lock Switch (Functions, but doesn't notify the SW layer. Need to write UEvent Listener)
    - External SD mounted at /sdcard/external_sd and linked to /mnt/sdcard2
    - goo.im app OTA update compatibility
    - Synced with CM9
    - New CM9 Bootanimation
    - nvflash package includes updated CWM with working backup/restore

    Added goo.im OTA compatibility so you can be automatically notified of future updates using the goo.im app.

    If you are updating from Alpha 1 or if you get errors in the market:
    1. Go to Settings > Apps > All
    2. Google Play Store (or Market) > Clear Cache and Force Stop
    3. Google Services Framework > Clear Data and Force Stop
    4. Restart

    The latest word from Lenovo is that we should have the proper kernel source code by next Friday or the following Monday.

    Here's some tweaks for everyone.

    Download the file linked below and place it in data/local for a corrected boot animation. Leave it zipped as is.

    http://www.mediafire.com/?42rfg769rv33vft

    Change your animation and transition scale to .5x for each in Settings > Developer Options

    Insert the following lines into your build.prop file in the system directory. If you are unsure of what you are doing I would not try it.

    These will enable deeper sleep on your device. Increase the wireless scan interval to 3 minutes. And help the overall graphics rendering and smoothness of the device. It also does a couple other things (removes USB debugging continuous notification, adds home launhcer to persistent memory)

    If you don't want to increase the resolution rendering of your device remove the last line of the tweak with the screen density line. Try it out though if unsure and see if you like it. I think IMO it renders very nice.

    pm.sleep_mode=1
    wifi.supplicant_scan_interval=180

    And i did a new build :)

    Untested, but should work.

    Also rearranged a few things in device/lenovo/k1

    tvd0405 thanks for the feedback

    It looks like it didn't like the fact that the external sdcard was mounted inside the internal storage. Which caused the Storage settings to crash.

    I posted Alpha version 1.6 which corrects the issue by moving the external sdcard mount back to /mnt/sdcard2, and creating a bind mount at /mnt/sdcard/external_sd. You will need to reboot once after flashing the update for the bind mount to take place.

    You now can use the GooManager app to get notifications and download OTA updates!
    If you do use GooManager, be sure to go into Settings and change the download location to somewhere in /mnt/sdcard2 so you will see the .zip's in CWM

    cornerstone looks awesome. Right now any free time I have will be spent trying to bring stability to the port, but I read that cyanogenmod may incorporate cornerstone in the future. That would surely make the process easier :)
