Hi,

I know it’s a bit late to install 2.3, but that’s the only I can install on RD-PQ, 2.4 is not supported.

I follow the steps properly, but lthor does nothing, hangs:

$ sudo apt-get install lthor

And it hangs here, nothing happens.
The phone has 2.2.1 and is in download (U-Boot) mode (vol down&power), and connected via USB (I can also see on phone screen: Cable is connected)
I am tried on Ubuntu 14.04 and 16.04 – same. At this step lthor hangs, no error, no progress, just does nothing. I have to Ctrl+C.
Same happens if I try to flash the boot image and the platform Image first, without bootloader.
The current 2.2.1 is not touched at all, it still works – so lthor does nothing.

.

Also same happens even if the phone is not connected to the PC!! No error message, nothing.

.

Any suggestion, what to check, try, see?
Thanks.

Edit:

I tried “lthor -c” with phone connected via usb in download mode, and I got:

.

$ lthor -c
