Selecting the right ROM is very important. If your phone is carrier unlocked and it does not have any carrier branding then you can download ROM of any country that is not branded.

Are you sure you are installing the right firmware?

Yeah, I think so, because it says it is for my device’s model.
Now I have tried odin307, flashing completed and odin said passed, tablet restarted and came up, but after awhile same error is back. Is my device hardware faulty already? Is there anything else I can try to fix it. Thanks again.

If you installed the firmware successfully and you are still getting this error. Most probably it is the hardware issue, or your device is too old now and its hardware has malfunctioned.
