I'm trying to use Downgrader 2.0 on my Paperwhite 2 5.12.2 to downgrade it to 5.12.1
I've downloaded firmware file (from Amazon's servers by editing download link of current FW 5.12.2.2) and copied it to root, then added "downgrader" dir to "extensions". After safe USB ejection Kindle immediately shows popup:
"Update Error. An invalid update file has been loaded on your device. Please go to
www.kindle.com/support to access the Kindle Software Update page or to contact Kindle Customer Service for assistance."
After that, when I go to KUAL and select Downgrader, I'm choosing PW2 but nothing happens - Kindle is deleting "wrong" FW file from root automatically.
Do you know how can I ommit that automatic FW file delete behavior and proceed with downgrade process?
Thank you in advance!
