    Default MOD: 2000 Modes for ASTRO25 Radios

    2000 MODE ENHANCEMENT FOR ASTRO25 RADIOS


    IMPORTANT: This release is COMPATIBLE ONLY with codeplug/firmware structures of R12.00.00 or NEWER. If you have FPP+Trunking and a CPS R09.0x.xx configuration, this WILL cause a codeplug error. ONLY PROCEED IF YOU ARE CERTAIN YOUR RADIO MEETS THE REQUIREMENTS.



    The P25 Forums technical team is pleased to present the following utility which will modify the security partition of ASTRO25 series radios to support 2000 modes.

    Motorola does not offer a 2000-mode Flashport upgrade; They should thank us and take notes.

    First, there are some things you need to know before using the attached utility.


    Technical background:


    This mod works on ALL ASTRO25-series radios. Portables and Mobiles. All ASTRO25-series radios use the same mode-provisioning configuration. CPS does limit the ASTRO Spectra Plus (4M and 8M versions) to 512 modes; there's no way to change this unfortunately.

    In the ASTRO25 Feature Descriptor Block (FDB), which is included in the security partition, Motorola has configured mode-provisioning like this:

    Block 4101, Offset 23:

    7 6 5 4 3 2 1 0
    0 0 0 0 0 0 0 0

    7 -
    6 -
    5 -
    4 -
    3 -
    2 - 1024 Modes
    1 - 512 Modes
    0 - 256 Modes


    Block 4101, Offset 25:


    7 6 5 4 3 2 1 0
    0 0 0 0 0 0 0 0

    7 - 128 modes
    6 - 64 modes
    5 - 32 modes
    4 - 16 modes
    3 - 8 modes
    2 - 4 modes
    1 - 2 modes
    0 - 1 mode

    Motorola provisions XTS2500 M2/M3 for 870 modes, and the XTS5000 M2/M3 for 1000 modes, by enabling certain bits in the mode-provisioning fields.

    The mod simply changes the values of offsets 23 and 25, to 07 and D0, respectively. This adds up to 2000. (The maximum limit is 2047, but we won't be greedy)

    >R12.00.00 Firmware and CPS support the changes without any problems whatsoever.

    Be aware CPS reads WILL take longer, IF you are USING a large number of modes. The additional time is related to the extra CPU cycles required by CPS, to unpack the codeplug after a read has taken place. If you DO NOT USE a ridiculous number of modes, it will not take any longer than normal to unpack the codeplug. We're just adding the capability to use the extra modes, if you choose to do so.



    Anything else I need to know?

    Yes. The change is permanent. There is no way of reverting, unless we choose to release another script which will put the maximum modes back to default specs. Do not perform this modification if you are prone to "post-mod remorse".

    The change does NOT make any "weird" or "hacked" changes to the codeplug, which could impact normal operation of the radio.

    FPP is still limited to 240 channels (15 zones of 16 channels), but you will be able to utilize 1760 other non-FPP modes. This mod does not add FPP.

    The mod is more of a benefit to trunking users than it is to conventional applications, as you can take advantage of all the extra talkgroup capacity for multiple-system monitoring.

    The mod WILL NOT brick your radio so long as the >R12.00.00 requirement is met.


    How do I use it?

    IMPORTANT: This release is COMPATIBLE ONLY with codeplug/firmware structures of R12.00.00 or NEWER. If you have FPP+Trunking and a CPS R09.0x.xx configuration, this WILL cause a codeplug error. ONLY PROCEED IF YOU ARE CERTAIN YOUR RADIO MEETS THE REQUIREMENTS.

    Download the attached zip file and install the CPFix application. It is not compatible on Windows 7 64-bit computers. Sorry.

    If you have already downloaded and installed the TMS-to-PWR mod from another thread, you do not need to download the entire installer again. Simply download the file called CpFixFilePackage_2K.zip and unzip the file called CpFixFilePackage.enc into:

    C:\Program Files\Motorola\CPFix\

    It will prompt you to overwrite the existing CpFixFilePackage.enc file. You may choose "YES".

    Beware you have just overwritten the script for the TMS-to-PWR mod. If you wish to utilize that file again, make a backup of the C:\Program Files\Motorola\CPFix\CpFixFilePackage.enc file first.

    Connect a radio to the programming cable.
    Connect programming cable to computer.
    Run CPFix.exe
    Select port which radio is connected to.
    Click "GO".
    Wait for the progress bar to complete.
    Click "Cancel" to exit the program, or connect another radio and click "Go".
    Done.



    Mod is temporarily removed until our coding team can resolve a problem with 9600 trunking compatibility, which is causing some errors.
