XG-100M w/ HHCH731 Frozen Screen, No Audio

[PinellasFL_Scanner]

I have an XG-100M connected to a HHCH731 and it was working perfectly until yesterday when I was scrolling through channels and it froze as I passed from the 16th to the 17th channel in a conventional zone. Additionally, there is no RX audio (but I do get a green light on the control head) and it will not TX. I'm able to read/write personalities just fine, but the handheld control head is still frozen except for the volume control. I was wondering if re-flashing firmware might help but am having trouble getting that to work with the control head completely frozen. Any ideas for further troubleshooting / fixes?

Usually just a power cycle will clear a lot of problems, but here, can't ruel out a failure in the HHC.

Thanks for the response. Power cycle was my first thought (including a full disconnect) but that didn't work. I ended up connecting via putty and have an error code:

There have been 1 fatal errors. The last error cod e was 509
Last error code was PI_INCR_PERS_ERROR Increased Personality files are not present

I found another thread that references the same error, but there may have been more going on with the radio in that thread. Looks like the resolution may have been upgrading firmware and changing the mission plan out. I tried making a simple mission plan and loading that, but it didn't work. I don't want to flash the firmware unless absolutely necessary. Does anyone have experience with this error code?

Do you have another control head to test with, maybe a CH-721? I would start there to rule out an issue with the 731. Another option is to wipe the memory using the information I posted here, and then do a reload of the personalities; If there is corruption, this might help: Harris XG-25P Can't put into program mode INV SYS

Swapping out the control head would be the easy solution, but I'm traveling now and won't have access to my CH-721 until mid-April. It certainly could be a hardware failure with the HHCH, but the buttons to put it into program mode are working fine so it's not completely dead.

I tried wiping the memory using the procedure linked above. It succeeded without error, and the radio appeared to be blanked out. I made a new personality with two weather frequencies and a simplex channel and loaded it in, but it was back to status quo--green light for RX, no audio, no functionality with the control head. All of this with multiple shut downs in between steps.

Is there a good way to completely clear out personalities with a serial command? I tried booting into burnapp mode with atz1. I followed the defrag routine from TSM36-02C and ran some other commands that I could find looking for errors including GET_FLASH_STATS, SHOWFLASHNFO. There were no errors. I found erase commands to hit different parts of the memory, but I'm not sure where personalities would be stored and don't want to nuke anything I can't fix.

I falso found this document that references previous size limits for personality files, but that doesn't seem to be an issue with RPM14. I haven't been able to find the maintenance manual (14221-1200-5000, Rev. B) online so I can read up more on that error specifically, but it's weird that re-loading the personality doesn't fix the probem.

I'm using the DB9 on the brick connected directly to my computer without any sort of USB/serial converter, if that matters. Here's what I'm seeing over serial:

You can clear the errors with Putty then see if that 509 error is persistant.

I would also recommend connecting a CH-721 and see what happens. You can chase a lot of other things and get nowhere if its a control head issue so eliminate that as a possibility first.

Thanks for all the replies. I have a CH-721 at home, but will be on the road until mid April. I've reached out to see if I can borrow one before then. As much as I'd like to have a working radio for the next two weeks, I also don't want to risk a firmware upgrade that might not even be necessary.

I did clear the error with Putty, and the 509 error is indeed persistent. It doesn't come back immediately, but after a minute or two it's there again and the fatal error count keeps increasing.

Hmph. That 509 error is sort of a catch all, If you have all the codes handy, you can sift through the log memory and find details.

I was finally able to get back to my CH-721 and swap it out. When I did that, the radio worked so it seems like the issue is probably with the handheld control head. I pulled the firmware version for that, and it shows up as "Not Applicable." I tried running the firmware upgrade for the HHCH, and after running for a while got a "Completed" message but the progress bar didn't extend all the way over. I let it sit for about 20 minutes but nothing happened. Was I just too impatient or do I need to run any commands to finalize the firmware upgrade after loading it from RPM?
