Just posting an update because the last comments on the XPR8300 is wrong. The latest CPS 15 firmware is R02.40.20. The latest CPS 2.0 firmware is R02.09.00.13. Just obtained the info from Motorola. They no longer support it and recommended I contact a local dealer because they usually have copies of the firmware. you cannot download them from myview. This is based on the conversation I had today with Motorola Mototrbo dept. If anyone has anything different please site the links from Motorola proving otherwise. I'm probably going to leave my firmware alone unless there is some special benefit going to R02.09.00.13.
By the way the information you quoted is mostly just plain WRONG ---
If you go to the release notes for Version: R2.9.7 Date: November 9, 2018 you will see on Page 5 --
Repeater – XPR 8300/8400 -- R02.09.00.12_R19.00.03 (XPR/MTR) for CPS Version - CPS V16.0 Build 827
If you go to the Release notes for Version: R2.10 Date: May 13, 2019 you will see on Page 7 ---
Repeater - XPR 8380/XPR 8400 -- R02.10.00.05_R20.00.02 for CPS Version - CPS V16.0 Build 828
NOTE THE change between XPR-8300 and XPR-8380 specifically between the two releases.
CPS 2.0 is a M2020.01 (New release notation) child. An while you can usually update/program subscribers and repeaters on older firmware with latter releases of RM/CPS, this is not always the case.
