How to downgrade if you already have telnet access and your run.sh is being executed:
1. fil-up run.sh with this code:

   #!/bin/sh
   if [ -f /mtd_rwarea/Version.0 ] ; then
   echo SWU_T-VALDEUC_001000_I04_ES000DS000KS000RS000_100205 > /mtd_rwarea/Version.0
   else
   echo SWU_T-VALDEUC_001000_I04_ES000DS000KS000RS000_100205 > /mtd_rwarea/Version.1
   fi
   sync 

2. Do not reboot TV, attach USB with firmware version you want to install (T-VALDEUC....)
3. Go to "Help -> Software Upgrade -> USB" and TV should accept firmware to downgrade

• Attention - code above only for T-VALDEUC

• When editing scripts, always make sure line breaks are done with unix style "LF", NOT Windows' "CRLF"!
