DNS does not work.
Do you have root on your TV?

If you have console access, then we have some experimental lib, which unlocks downgrade. Tested and is ok on E/F/H series (available in Extra section), but it wasn`t fully tested on D series. lib was checked on D6500 but only up to final step (press yes to upgrade).
Risky thing, but i`m sure, it will for 99 percent work, just no proper TV to check. In the other hand - no garantee you don`t brick your TV without possibility to repair - only mainboard replacement is possible in this case.

lib was checked on D6500 but only up to final step (press yes to upgrade).
on TV - T-GASDEUC-1018
on USB - T-GASDEUC-1016

Code: Select all


no libFWdowngrade.so:

[AP_SWU/Fatal] 583 : [ProcessCheckUSB][line:1098] USB Version is Fail
[AP_SWU/Fatal] 584 : [IsDualBSP][line:1440] This is Dual BSP!!!!!!!!!!!!!!!!!!
[AP_SWU/Fatal] 585 : [m_CheckEmanualList][line:9087] dir [/dtv/usb/sdb/T-GASDEUC/image/eManual] is not exist
[AP_SWU/Fatal] 586 : [CheckFileList][line:5545] /dtv/usb/sdb/T-GASDEUC/image/ is not exist

[AP_SWU/Fatal] 592 : [ProcessCheckUSB][line:1165] There is no USB SW Image!!!! 
Result - Popup - no file available to upgrade...

Code: Select all

with libFWdowngrade.so

[AP_SWU/Fatal] 684 : [IsDualBSP][line:1440] This is Dual BSP!!!!!!!!!!!!!!!!!!
[AP_SWU/Fatal] 685 : [m_CheckEmanualList][line:9087] dir [/dtv/usb/sda1/T-GASDEUC/image/eManual] is not exist
[AP_SWU/Fatal] 686 : [GetSecureImageVersion][line:4677] USB downgrade stop 1.2 version GetSecureImageVersion
[AP_SWU/Fatal] 687 : [CheckFileExist][line:1646] IS_STANDALONE_APP is 1. File Check will be skipped
And the result - popup appeared on the screen - "valid version on USB found, do you want to proceed with fw upgrade? yes no."

Seems, with lib TV recognized lower firmware on USB and asked for installation of new firmware.

I wonder if I didn't remove D code in lib to protect the innocent, possible you've got a "special" version (I don't have anymore :D )
You can publish it here anyway, I leave thread in Extras section because of fw download list. Lib has less value now almost all E/F/H have 0000 fw...
I do NOT receive any PM. Please use forum.

I have that special version on my tv. Since DNS trick for D series downgrade does not work anymore, lib is only option for downgrade now.
I just curious about how root works on D8000 on latest firmware which needs to be downgraded...
