IM-A820L用CWM时开启自动更新造成Recovery循环的原因（其他泛泰机型可参考）

造成循环的关键代码在phoneinfo分区中，也就是mmcblk0p10中

这段代码的作用似乎就是开机进入Recovery，也就是说造成循环

解决办法就是将其全部置零

dd if=/dev/zero bs=512 seek=264 count=1 conv=notrunc of=/dev/block/mmcblk0p10

对CWMRecovery的修改，只要添加文件sbin\postrecoveryboot.sh

#!/sbin/sh

# get out of recovery loop
# by SuKY
busybox dd if=/dev/zero bs=512 seek=264 count=1 conv=notrunc of=/dev/block/mmcblk0p10

如此便可自动跳出Recovery循环

提醒：使用CWM虽然不能自动OTA，但是我没记错的话OTA包其实就是/sdcard/image/update.zip

奉上个人使用的Recovery，根据本人的机子修改了时间

若要修改，只需要改init.rc中的

	sysclktz 0

将0改为合适的数值即可（换算很麻烦的，还是自行尝试吧）
CWMRecovery.img

恩，你没看错，下面的的确是binx刷机包哦，本人试过，求测试
CWMRecovery.binx
