troublw with firmware

Hello, help me please

I'm having problems after updating the firmware.
The problem is after binding the transmitter and the receiver (fixed ID)
The receiver does not receive a signal from the transmitter when i try start motors (Both sticks to the lower left and right position). The motors dont run.
In the original firmware is no such problem.

And another problem, when I back to the original firmware, the fonts after the firmware becomes unreadable. I donr know why.

Thanks for the answers

For your ID problem: as far as I know the fixed IDs from the Walkera stock firmware have to be reset in the rx (bind with deviation without ID), then set a new one with deviation.

model: Walkera Devo 10
Protocol: DEVO

Yes I did as you say(you need Upgrade firmware and library).
But after the upgrade is what I see on the display:

rbe2012,
maybe what you say, but
the problem is that the receiver is not to see the transmitter and constantly flashes red (signal detection)
