[SOLVED] Problem after updating fw to 3011

[nachips]

Hi, i have samsung UA60C6900 tv. I've updated my tv to fw 3011 and after the update my tv got a problem. When i tried to change the country, the option list is invisible after keying in the pin and i checked most of the option for plug and play are also invisible. I've tried to factory reset the tv but it does not work too. So i hope with all your expertise in this, you can help me solve this problem. Lastly thanks for the help.

you have to enable extended service menu. Check c series wiki for tuto...

I still can't change it after going to the service menu. Here's a screenshot of what the problem is:

Looks like your appdata.img was not properly written. As you see -fonts are crappy, like some of them are missing. I mean - firmware upgrade failure.
To correct this you have few options:
1. Do firmware upgrade trough USB or internet
2. Flash required image manually trough telnet. But root access is needed and this is for advanced users only, you can damage tv easily with wrong/incorrect command.
3. Toggle to alternative firmware. Root access is needed as well.

Issue is 100% to be fixed using root access. I don`t know if widget way to get root will work on T-VALDAAC (this is your firmware name?), try first.

I'll try to do option 1 later on. And my firmware is T-VALDEUC. Thanks for the help, will update the outcome.

For T-VALDEUC you can use zero firmware for downgrade, T-VALDEUC-0000.0. After this you can install any firmware version you need.
