It is possible to flash a backup from another TV?

Hi All,

it is possible to do a Backup of /dev/tbml8 and /dev/tbml9 or rather /dev/tbml10 and /dev/tbml11 Partitions from one TV and flash this on another TV?

I guess yes if they have same model and firmware.
This could be crucial on CI+ models because of authld.

My problem is, i've flashed my /dev/tbml10 and /dev/tbml11 Partitions with 3000 FW by Hand, this cause the Problems with the authld.
On my /dev/tbml8 and /dev/tbml9 Partitions i have the 3001 FW that i've flashed by TV internal flash routine.

I'm seraching for a way to revert my FW back to the good one with PVR Function.

Oops.
That come in my mind, even you have chance of successfully recover your partitions.

You needed to try external boot with USB Flash. Once you booted older version via externalUSB, I guess you can update your TV flash from std menu.

Also this might help:

Hi Erdem,

I thought usb boot method works only on non CI+ TVs isn't?

It sounds good that some people works on deactivate or to fool the authld.

It works on CI+ devices too. I think authld don't kill us if you boot external linux kernel because there is no authld on kernel
But don't know exact instructions about it.
