• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

HT1250 Firmware Help Needed

I have an HT1250, version 1 firmware. I want to upgrade to the latest firmware, 05.13.04. When I try, I get a checksum error from the radio. The radio is old but I called the Big /\/\ and was told that I should be able to upgrade the first HT1250 that was made to the current firmware. I do not have any firmware versions older than 5 series. I thought maybe it needed to be updated in steps? (1 to 3 to 5) or something like that.

Anyone with experience doing this have any suggestions?

I got it done. For reference if anyone ever gets to this page via search or Google:

R01.xx.xx cannot be upgraded directly to R05.xx.xx. You need to go through an in-between version. I dug through our old CD's and found R03.01.03 and upgraded to that firmware which worked fine. Then I upgraded to R05.13.04 and it worked just fine.

At one point, Motorola included updated firware versions on the CPS CD's. Fortunately, I found a CD from 2002 which had the R03.01.03 version on it.

I have a quick question about the HT1250 firmware. I have a R01.xx.xx radio. My dept just received a handful of new HT1250s with R05.xx.xx firmware. I don't know if we have any firmware on CDs. If we had a radio with R03.xx.xx firmware, can the firmware be pulled off the newer radios, or do you have to have a firmware file from Motorola? Thanks.

You need the firmware file, you cannot copy it from an existing radio. You also need the HLN9742B flashing adapter. You can make an adapter, the pinout can be found on Batlabs. The R01.xx.xx needs to be upgraded to R03.xx.xx and then both R03.xx.xx radios can be bumped to R05.13.04. Once you bump the firmware to R05.13.04, you MUST use CPS version R06.09.06 for programming; older CPS will no longer work.

OK thanks for the info. I didn't realize how old my radio was until we got several new radios and updated CPS software, as it refused to program my radio.

I have done several of these that were R1.00.05 with lab tool. These early radios sucked but the firmware update is the way to fix it.

If you want to pay shipping, I'll update it to the latest firmware.
