help for provide rmpp version 3.17、3.18.

[asking002]

I have just installed koreader on rmpp with firmware version 3.18.2.3，unfortunately， the device update to 3.19 automately. Then all effort was in vain.
I find you have a solution to rollback firmware version, but rmpp doesn't support for restore directly, and if reinstall the firmware, the latest version is 3.16, could pls to provide 3.18.2.3, or enable to restore to the last version.
Thanks a lot.

#/bin/bash
OLDPART=$(< /sys/devices/platform/lpgpr/root_part)
if [[ $OLDPART  ==  "a" ]]; then
    NEWPART="b"
else
    NEWPART="a"
fi
echo $NEWPART > /sys/devices/platform/lpgpr/root_part

You can use this script to switch to the previous root partition, with the OS version that is installed on it.

Is it possible to release 3.18 fw later？I can wait for a while, prefer a clean OS.

@Eeems it works，back to 3.18. and still fight to install koreader.
