Hi this should work like this.
THis code should be changed at the widget to only copy the Version.1 to the TV:
Code: Select all
Replace this:
FilePlugind.Copy("$USB_DIR/sda1/usb_mount", "/mtd_rwarea"); //???????? ????? ? ?????? usb_hotplug.sh ?? ?????
FilePlugind.Copy("/sbin/usb_mount", "$USB_DIR/sda1/test"); //???????? ?????? /sbin/usb_mount ?? ?????? ? ????? test
FilePlugind.Copy("/sbin", "$USB_DIR/sda1/test"); //???????? ?????? /sbin ?? ?????? ? ????? test
FilePlugind.Copy("/mtd_rwarea", "$USB_DIR/sda1/test"); //???????? ?????? /mtd_rwarea ?? ?????? ? ????? test, ??? ???????? ?????? usb_hotplug.sh
with this:
FilePlugind.Copy("$USB_DIR/sda1/Version.1", "/mtd_rwarea");
Version.1 has to be at the root of the USB stick ...and has to contain the information of the previous FW version.
Probably $USB has to be raplaced witv /dtv/usb/ if it doesn?t work ...
Should be working like this.
Regards

Bastler, do you know, how to know what is alternative firmware if tv has not been upgraded after it has bought? I mean, what identificator is needed to write to Version.0 (or Version.1)?

@ Juis
What do you mean exactly ?! Do you mean how the TV decides if it is able to have an alternative Firmware or if this feature is diabled ?!

I mean, how do you know what firmware ID you need to write in Version.x file to activate alternative firmware. What if here is no alternative fw or it is others.

Ah I see ... hm that?s a good question, bust as far as I know or have seen the TV?s already had FW Versions > 1008 ... so I think the 1008 alwasy is a good solution for the Version.1 file if downgrading is whished

Theoretically the
partially automated way might work, i think. Run revert.sh script from console... Who can confirm?

Hi,
what do you want to achieve ? Why not just downgrading Firmware by Version.1 method ?
