If I'm not mistaken, that's the reason why you flashed this firmware on your drive. However, that firmware version is considered as the "latest one", just as the RG21 version, because the only difference is that it disables this feature.</P><P></P><P>Nevertheless, once the firmware has been updated to the "latest" one, it's not possible to downgrade the firmware of the drive. In this particular case, you would not be really downgrading the firmware version, but as the RG2P firmware is considered as a latest firmware version, you won't be able to flash any other firmware, even though it's the RG21. That's the reason why you are getting that message.</P><P></P><P>However, as I mentioned, the only difference is the DEVSLEEP feature, which is disabled, but the drive should work fine and you should not have any issues with it.</P><P></P><P>I hope this information answers your question.</P><P></P><P>Have a nice day.</P><P></P><P>Regards,</P>Diego V.

Thanks. In future, if there is newer version, probably then can switch it back, to regular version.</P> Tue, 23 Oct 2018 17:09:15 GMT https://community.solidigm.com/t5/solid-state-drives-nand/535-ssd240gb-switch-firmware-rg2p-to-regular-rg21/m-p/10411#M2097 idata 2018-10-23T17:09:15Z https://community.solidigm.com/t5/solid-state-drives-nand/535-ssd240gb-switch-firmware-rg2p-to-regular-rg21/m-p/10412#M2098 <P>Hi SimeonGG,</P>That's correct. In that case, if there is a newer firmware version in future, you should be able to update it. Regards,Diego V.
