ผมไปอ่านเจอมาครับ ไม่ทราบว่า มีใครเคยใช้บ้างหรือไม่ น่าจะสะดวกดี ไม่ต้องใช้ PC ก็ upgrade firmware ด้วย Odin ได้

Description

Mobile ODIN – Full firmware flashing straight from the device itself!
Mobile ODIN is the on-device firmware flasher of choice. Just throw those firmware files on your (internal or external) SD card, start Mobile ODIN and flash away.
!!! Your device must be rooted to be able to use Mobile ODIN !!!
If you use the EverRoot option, Mobile ODIN will root the firmware while you flash it. Checking out that new leaked firmware? No reason to lose root!
Currently supported devices:
– Samsung Galaxy S2 GT-I9100
– Samsung Galaxy Note GT-N7000
– Samsung Galaxy S GT-I9000 *NEW*
– Samsung Galaxy Tab 7″ GT-P1000 *NEW*
More devices to come!
Flashing with Mobile ODIN does NOT increase your custom kernel flash counter or make the yellow warning triangle appear.
