I have an j-beaked PW with newest firmware 5.3.3. I want to DOWNGRADE to 5.3.1.
Problem: it's not possible...
I used this BIN-file
I chose the 'normal way' (...--> update kindle --> restart)
When restarting, the reader just do not install the older firmware. No dialogue, no message. Just restarting and booting into 5.3.3.
I also made a full RESET of the reader first and then tried to install the older firmware. Same behaviour.
