SamyGO

Both are ok, these are from different sources. Btw, no info about any exploit or trojan.

I did not notice the size difference.
Looking at the archive contents, it's mainly due to differently sized appdata.img.sec,

Anyway, go with "SamyGo's" T-VALDEUC_0000.zip, it's from a reliable source
and tested by many users...

Thank you very much juuso and Demaciado.

One last question: since my downgrade is aimed at unlocking the service menu and have all of its features available, so that I can change the "Local set" from EU_ONLY to ITALY and have MHP, LCN and EPG Guide fully working on my LED TV, towards which "older" firmware should I downgrade ?
Should I load T-VALDEUC_3005.1 or T-VALDEUC_3008.3 ?

I would suggest before you downgrade your FW you could try the ruTVcommunicator network trick, there is a chance that it unlocks the full-servicemenu even with your current firmware...

"more older the firmware more better"
I'm still on 1016 and happy with it. Furthermore it's easy to make an usb-upgrade if you are not happy with an older firmware. If you want to downgrade you always have to go over 0000!

* "always" applies only to non-rooted TV

Well guys, I'm happy to say that, thanks to your precious advices, I successfully managed to "italianize" my LED UE46C7000WP !

Here is the procedure I followed (I'm confident it might help other people with the same necessities):
01 - turned ON the HOTEL MODE, switched ON the TV in SERVICE MODE and made a CLONE TV TO USB command (just in order to have a backup available): finally I turned back to OFF the HOTEL MODE;
02 - loaded by USB the 0000 firmware (from this point beyond a "NOT FOR SALE" message was displayed in the TV every time I switched channels);
03 - loaded by USB the 3008.3 firmware (the message above disappeared);
04 - turned ON the HOTEL MODE, switched ON the TV in SERVICE MODE and made all the required changes to LOCAL SET and COUNTRY (inside the OPTION MENU) and to REGION and INFO LINK COUNTRY (inside the CONTROL --> SUBOPTION MENU);
05 - took pictures of all the menus and submenus inside the SERVICE MODE MENU (since I wasn't sure that such settings would be kept after the factory reset);
06 - made a FACTORY RESET;
07- switched the TV ON, installed the channels (as it was the first time) and finally had interactive services (i.e. red button on RAI channels) active and channels automaticcally sorted !

Once again I want to thank all the people which supported me on this forum, which is absolutely #1 !

There is just one question pending
Some channels which were formerly available in my previous channel list (compiled setting Spain as country), now that the only country available is Italy are not available anymore (i.e. RAI HD).
Is there a specific item in the service menu which has to be set for this aim or might this depend on the Firmware currently installed ?

Please stop coloring your text.

DONE, also for earlier posts. Sorry

2 final notes:

1) after the FACTORY RESET, the purchase date displayed in the Service Mode Menu had changed from the original value to the date of the Downgrade;

2) since I opened a new discussion with regards to the problem of auto-update of the channel list, this thread might be marked as [SOLVED].
