UE40C6700 bricked on firmware downgrade

[juusso]

If I was to downgrade to an earlier version firmware can someone please clarify if I should modify the Version.1 file or should I replace it with a modified Version.0 file ?
Thanks

You have to modify EXISTING Version file (either Version.1 - in your case, or Version.0).
So:
1. connect to TV over telnet
2. modify Version.1 by replacing ID string (just copy-paste in your console):

Code: Select all

echo SWU_T-VALDEUC_001008_I04_ES000DS000KS000RS000_100403 > /mtd_rwarea/Version.1

3. do not reboot TV
4. Attach USB with lower firmware you want to upgrade to
5. Follow instructions on TV screen until TV reboots after successful firmware upgrade.
6. Thats all.

I can confirm, it works.
