MTK JB版本的recovery mode下使用外置T卡升级

1、请您将Recovery.fstab (mediatek\config[Project])中mount point 为/sdcard的项修改为如下内容：
/sdcardvFAT/dev/block/mmcblk1p1 /dev/block/mmcblk1
2、请将alps/bootable/recovery/roots.cpp 下353-357行：

#else
} else if (!strcmp(mount_point, "/sdcard") && has_fat && strcmp(device, dev[FAT_INDEX])) {
device_volumes[num_volumes].device = strdup(dev[FAT_INDEX]);
device_volumes[num_volumes].device2 = device2 ? strdup(device2) : null;
#endif

修改为：

[hide]#else
} else if (!strcmp(mount_point, "/sdcard") && has_fat) {
device_volumes[num_volumes].device = strdup("/dev/block/mmcblk1p1")
device_volumes[num_volumes].device2 = strdup("/dev/block/mmcblk1");
#endif

3、重新编译整个工程new
