By now, the latest kernel edition is: 2.6.32.9-g82fb087. To update to chinese offical release edition (this rom include 2 Languages: English and Chinese and does not has google service, that means you need to install it yourself), you need to: 1. flash chinese offical xt702 sgc1260/2040/3040 sbf image. The link of SGC3040.sbf is http://file.geeka.net/system/20107131112.rar 2. download offical update.zip. The link is http://www.motorola.com/Consumers/CN...entPages/XT702 method:reboot the mobilephone, use rsd lite to flash the sbf, then put the update.zip to the root of sdcard. Then press x or camera button to the recovery mode. Select apply update. Waiting. Then select reboot. Now you have offical 2.2!!Now I supply a nandroid recovery file. You just need to use nandroid -> restore then select this document. Your kernel will be the latest-----------------------------------------------------------------------------After two days test, I'm sure this is still a test edition, not final edition, it is still has DSI problem, in other words, it is still not stable. Also, China has canceled the update link.
