Thanks for the helpful feedback. One thing I emphasize in OP is that since this ROM comes from a different manufacturer (and hence a different device), arbitrarily flashing zips and addons intended for that device to the Atrix is not advisable. For example here is a portion of vincom's "themeing_v8.zip" updater-script:
Code:
mount("ext4", "EMMC", "/dev/block/mmcblk0p24", "/system");
package_extract_dir("system", "/system");
unmount("/system");
ui_print("Done");
Note that for SGS2 Skyrocket, the EMMC device name for the /system partition is: /dev/block/mmcblk0p24, whereas for Atrix it is /dev/block/mmcblk0p12.
Same issue for multi-language keyboard.
So we would need to port theming and keyboard to the Atrix as well.
[UPDATE 08 Mar 2013, 1320 PST] And here they are, tested working:
Theme: http://www.mediafire.com/?a0a2vq134hu1aok
Keyboard: http://www.mediafire.com/?jjdd7io6jssn4ue
Combined, these two files would add another 15MB of compressed system files --- almost all of it for keyboard.
FYI, I decompiled the LatinIME.apk inside the keyboard zip and could not find Chinese language. I also looked at epinter's CM10 and could not find it.
[UPDATE 08 Mar 2013, 1350 PST] Correction: It appears that Chinese language is stored under LatinIME/res/values-zh-rCN though it does not show up in System Settings > Language &input > Language menu.
Note: Here, "theming" is just the theme infrastructure, not a package of one or more themes. There are many offerings for CM10 theme packages.
Thanks again!
