MD782 U(2) firmware upgrade path

[dcathxt]

Hello,

I recently acquired a bunch of MD782 U(2) radios from a school district; I build low budget racecar radio setups for hobbyists.

Many of these radios have very old versions of firmware (some are V4.5) and I'd like to get them up to a more current version so I don't have to constantly install/uninstall different versions of the CPS to program them, maintain different program files, etc. The issue i'm having is that if you don't choose the right firmware upgrade path, it seems as though the firmware application won't even recognize that the radio is connected.

I have the 5.05.14.004 firmware upgrade but it won't seem to recognize the V4.5 radio. I have a similar problem upgrading from V7 firmware as well. I've had success going from V8 to V9.

It seems as though I'm either doing something wrong or there are a bunch more intermediate versions of the firmware that I don't have. I'd love to get them all to V9 of the firmware for commonality purposes.

Please note - I am not asking for free firmware. Being that this is a discontinued radio, I don't know how to get it legally from Hytera - I would love some advice if i'm wrong on that as well. I'm just not sure if my problem is that I have the wrong firmware.

Has anyone experienced this that can offer some advice?

You have to find a compatible version of upgrader. Hytera upgraders DOES NOT work like this: one upgrader upgrades from any version to related version, NO! They work like: "I can firmware upgrade from this low version to this upper version"; e.g 6 to 8 or 8.0 to 8.5

That means you have to upgrade several times if you want them full updated.

BTW I am surprised that upgrader v5.05.14.004 did not see your radio

Do you have the right programming cable? You have to have the one with the built in switch! I have the next version up and it goes down to like ver 4.0

Yes I have gotten all they have.. however they don't seem to have all of them.
Also having trouble going from 8.01.03.005 to 9.02.03.005. I don't have anything in between.

This shows my issue - I have the radio plugged in via USB and I have the programming cable switched to 'DL'. I've also tried with it switched to CPS and a programming cable without the switch altogether. The software seems to be in chinese but I think the dropdown would list the COM port if it was recognized.

Any further tips?

Click on these two chinese characters. It shouls give you a drop down box allowing you to switch the firmware upgrade to English.

Plug the programming cable in to both your computer and MD782. Then turn it on. You should be in firmware upgrade mode. Red led on nothing else I think from memory.

You should be able to select a programming port and really mess up your radio.
