    [ThinkTank] CyanogenMod for CMP741e

    So today I began playing around with CyanogenMod for the CMP741e.

    I believe it would be smart to first start off with CM9 versus CM10, as our device is already on ICS.

    So first thing I did was try to create a compatibility pack, I dumped the bootloader and got the script files from my running device:
    adb shell
    mkdir /sdcard/nanda
    mount -t vfat /dev/block/nanda /sdcard/nanda
    adb pull /sdcard/nanda
    From there I was able to get the script files that are made I was able to make a compatibility pack similar to a few other devices:
    Dev-Host - cmp741e-compatibilityfix-v1.zip - The Ultimate Free File Hosting / File Sharing Service

    From there I decided to see if we had a touchscreen, in which we did not, so I flashed the kernel from the device originally and that seemed to just boot to a blackscreen.

    At this point I am reinstalling my Ubuntu VM to play with our kernel to see if there can be some ramdisk simple edits that can be done to modify it to boot properly.

    As always I am making this thread to bounce ideas with others and others throw out their ideas. This has worked previously on other devices I have worked with so here's for the same!

    Looking at the script file from the dump after modyfying them to .fex I find the following:
    [recovery_key]
    key_min = 4
    key_max = 6


    Might be something interesting....

    Script files also confirm:
    ctp9_name = "gt811"


    Playing with Keytest.apk I found out the following:
    Power Button = Key 26
    Volume Down = Key 25
    Volume Up = Key 24

    Back button (circle) = Key 4

    So it seems that nothing is programmed at key 6...

    Nonetheless, if we change the script file it might be possible for us to do key 26+ key 25 and boot into recovery....
    What does everyone think?

    Thanks

    Thanks very much for this. As someone who is new to CM, can someone identify if this port has any issues on this device? Also, with this device, whats the process for installing this port?

    The only problem I've just found is that the system partition is full I have to investigate that but all the hardware does work.
    The Thunderbolt port does not have this problem. As to install it you need the custom recovery in the tut on how to install gapps
    copy the zip to your sdcard reboot into recovery do a factory wipe then install from zip and reboot system

    Unfortunately it continues to have a non-touch touchscreen issue. Would you care to share what changes you have done for the ports so others can try to work on it also.

    Thanks!

    Changes I made is that I made a copy of my boot.img and replaced the kernel modules with the ones from the factory image copied the idc files and placed them in /system/usr/idc. It seems that maybe my cmp741e has a different touchscreen driver than everyone else, mine seems to use zet6221 driver. Finally I replaced the /system/lib/hw/ audio related libraries with the one from the stock image
