UA40C7000WRXXA Reboot Loop (Bricked)

Hi Guys
I have long enjoyed my hacked UA40C7000 running SamyGO extensions, but in an attempt to install a Netflix widget I played around in the Service Mode menu and changed my region and after switching my TV back on it just restarts after 15 seconds and there is no reponse to the remote evening after cycling the power.
I read up and saw that this problem can only be fixed by reseting the eeprom. I have attched two pics. I think I have identified the eeprom I just wanted confirmation.

you have to reset it again. And perhaps you`ve set wrong values for your TV.

take spootlight, blindy enter to factory menu from standby mode and check your TV screen. sometimes some text is visible because of lcd backligt is off. Maybe it is your case.

Thanks juuso
I managed to reset the eeprom again, the tv is working now, the only problem I have now is that whenever I switch on the tv it gives me the error "Mainboard has been changed..." even thou all my settings have been saved and are working fine.

you have to enable extended service menu and set proper values. Seems somewhere you have "none". Check service menu...

All 100% TV is working nornally again Tahnks juuso
I have another issue now I cannot rehack the TV it won't read the settings from the usb
I read that you need to reformat using the ex-link cable
My tv has an ex-link port (looks like earphone jack) can I still use the usb TTL method via the vga?
