Sony kdl 40ex720 firmware update

A big thank you for all!
That was the problem: I copied only the file not the folder. And also a good news that, I reformatted my 4GB chinese led stick with RUFUS to MBR partition and USB update went down easily immediately, so doesn't need special low capacity stick for it.

PS: So far I have done many USB update, but almost all need to copy the (bin, pkg, etc.) file to root, not the folder. This is exception.

After a long time with no luck for me, from your success a started digging about that problem again. I tried what you suggested but for me still nothing. Can you please give us the exact procedure how do to the update? Thank you in advance!

As you can read above I made the update a chinese 4GB MBR FAT32 stick. Copied the above folder into its root, and attached it to the TV in power off. Pushed the connector to the mains, the TV was in out of order state. Then I pushed power+source together on TV tast, and then started to blinking Y-G led and the stick too, it started update immediately. If stick blinking continously Wait for long time. I think it restarted 2 times and finally started with baclight and normal working.
(I think the most important that the TV let in Y-G blinking state, the update will start if usb attached before or later.)

So i have to put the folder with the file inside on the root of the usb stick or just the bin file?
