• 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.

I finally decided to call Joey at Atlantic Radio. He issued a RMA to get it repaired. This seems to be a known issue. Thank you @Muxlow again for your assistance.

I've had the same experience as some of you described here. What is the bottom line solution? Can you reshare that firmware @Muxlow? Is Hytera planning on releasing a fixed firmware for this?

Hytera should have a updated fw out in 30 days or less

I had one of my HP782's fail and was just a black screen. Shut the radio off. Held the PTT and...orange? button i think while turning it on and the red light flashed then went solid and i was able to redo the fw upgrade and problem solved on that one radio

Thank you @Muxlow

That folder appears to be empty?

I've also tried this:

And finally am getting the Firmware Upgraded Successfully message, but after the upgrade I'm having the same issue.
I'm wondering if there is a new method of 'exiting' the DL mode on the radio?

Fixed

The H series upgrade process is in 2 steps. It will do its 1st part then say success on the batch upgrade program then have to click upgrade again to do the second part. This only applies if you have the manual box checked in the top right.
If you use auto then it does both parts by itself and you should see on the screen on the radio upgrade complete and shows the new fw version on it and a option on the radio to click ok

If you dont get that msg on the radio it didnt upgrade correctly and just try again.

Still getting the error that the bluetooth file does not exist. I guess I'll have to wait for the new firmware to be released.

so I don't get the 2 step process. It's only one step on my end, the radio doesn't reboot or anything.

Unless I'm missing something very obvious.

Your trying to update the HP not a PD?
When i updated 40 HP radios i loaded the terminal batch tool. Clicked AUTO in the top right. Plugged the radio in and hit upgrade. Started its process and after 60 seconds ish it said upgrade success or something similar and it was starting the second part that took alot longer.

Dont have a radio with me at the moment or id reload the fw and get a video of it. But if you click auto and retry the process again and wait until the radio reboots and shows the upgrade was success on the screen and shows the firmware version and push the - - to confirm

Will have an entire new look on the display and icons different. So if the display looks the same then it didnt take. Only have 1 issues out of the 40+ radios iv upgraded

What I did was the manual process, got the BT error, waited, and errored out. Then again, same result. Tried a restore, errored that can't roll back a version. When I power on the radio I get 3 red flashes on the indicator light, and a blank white screen, till I power it off.
No matter how many times I try the manual or the automatic process, it says it succeeds with the upgrade, but nothing changes on the actual radio. It's in a stuck state. No errors, no radio :)

3 red flashes means its in FW upgrade mode. Programming cable your using. Does it have a switch on it? one that says CPS and the other FW? If so make sure its in FW mode for doing upgrades. And CPS when not. Change the switch when the radio is off not on too

Whats the model number of the radio? See if i can get you a different restore file

The cable doesn't have a switch. I always upgraded these by pressing the PTT+TK buttons while turning on.

It stays on this mode even when the cable isn't connected. Just standalone.

Model is HP-782 BT/GPS

The PC152 cable does not have a CPS/DL switch. Or is there a version of this cable with a switch?

Hi, I have problem too, when I was trying to upgrade my HP685 to FW V3.0.12.015 first i had successful information about upgrade L2 and my hytera has reset to white screen, but I had to upgrade L3, so I took out the battery and put it back in and then my PC said "Unknown usb device (device descriptor request failed)" and my CPS and DMR Upgrade don't se connected hytera. Anyone had this issue ? What I can do with this?

No matter what I try, the system remains stuck in this state. The Upgrade tool doesn't appear to attempt an L2 or L3 upgrade. It simply runs, reboots, and displays "USB:2(1.0) Upgrading Finished." In Auto Mode, it keeps repeating this cycle endlessly.

Here is the latest FW that just came out
ver 3.1.20.006

Also here is what my batch upgrade window looked like after i did the update.

Upgrading L3 boot finished (took about 30 seconds)
Then radio reboot and went solid white screen with solid red light on top.
At times it seems like the program freezes at 95% but then after a couple mins it starts up again
Start to finish took 6 mins to complete and get the upgrade finished!

Radio reboots and shows Upgraded to A3.1.20.006 wtih a solid amber light and the option to confirm on the screen

Thank you, @Muxlow

Unfortunately, I'm not seeing the same results on my end, it's possible the radio may already be bricked.

Here's what I attempted:

Installed the 3.1.20.006 updater

Connected the radio via the appropriate cable

Powered on the radio while holding the PTT and TK buttons (device successfully entered DL mode)

Launched the software and confirmed it was set to Auto Mode

Upon attempting the upgrade, received the error: "Upgrade Failed! Query radio user define data error!"

At this point, it seems likely that the unit may be beyond recovery. We may need to proceed with an RMA.

Unfortunate, but it is what it is.

Interestingly, After using the tool you provided earlier, I imported a restore file from a previous version. Now, I'm essentially back to square one: the upgrade completes, but when I power on the radio, it only displays a white screen with a solid indicator light and it stays stuck in that state indefinitely.
