    This is only meant to be applied to be Coby MID7015 stock firmware, or custom firmware based on the original shipping MID7015 firmwares. If this is flashed on another Telechips device, it may very well result in a bootloop (such as the M701).

    This update.zip contains a fixed GPU driver (mali.ko). It is meant to be applied in recovery mode, and fixes graphical texture problems in the Coby MID7015 shipping firmware in games such as Angry Birds.

    You are not expected to lose any data with this patch, but please Nandroid to be safe.

    Requirements
    Coby Kyros MID7015
    Clockworkmod recovery installed, or device rooted
    Root required VM Heap Tool is to be used

    Download

    Download universal version here
    md5sum 7D571762481B3B3A5A19A69E1AFE9399
    This just replaces mali.ko, not build.prop, may require manual dalvikvm heapsize edit.

    You might be able to use VM Heap Tool (XDA) (Android Market) to set your heapsize to the recommended 24m.

    Download here for Watery Kyros 1.2b
    md5sum 73BF418EDC9A93CFAA575141B9990452
    This update.zip contains a fixed GPU driver (mali.ko) and a tweaked build.prop with LCD density set to 200 as in Watery Kyros, and dalvikvm is 24m. It is meant to be applied in recovery mode, and fixes graphical texture problems in the Coby MID7015 shipping firmware in games such as Angry Birds. Should also work on a fresh 7015A.

    Installation

    To install,
    Place the file onto your sdcard, then reboot to clockworkmod recovery
    To install in recovery mode, select 'install zip from sdcard', and select 'choose zip from sdcard' to proceed.

    You can use adb to push mali.ko to the location /system/lib/modules/ manually. Also make sure that your /system/build.prop has the property: dalvik.vm.heapsize=24m

    One tip: if you start seeing force closes on boot after this, increase dalvik.vm.heap in build.prop to 32 or 48. This value is the memory allotted to each instance of the java virtual machine. Hopefully this won't cause any issues with the graphics driver.

    Is this expected to be compatible with watery Kyros?

    Would we need to set permissions on this file? I don't see that in the updater script.

    Default is 644, which is fine.

    You guys this works fantastic even on stock 2.1. Glad to see you have hooked up with Fun_, he is a good resource. I did boost up to 32 instead of 24.

    Thanks

    so cool! It works! Awesome! Thanks!

    I thought it might also fix the issue of the picture of friends not showing in Facebook but in vain... but I'm more happy that Angry birds now works!

    Thanks again

    l_n you should apply this in your next build.

    Can I find a reason why my mid7015 will not find my recovery_image file while terminal mode?

    It was labeled beta because we had no guinea pigs to test before posting.
