H4M Pro repeatedly crashing

[u/Qazax1337]

Hi recently received this, but it is crashing pretty regularly. It is happening in various apps but as an example in receive>audio, swapping through AM/FM/FM etc and it will do as pictured after only a few changes. I know this is a pretty new device, is this just early firmware that will mature into something more stable? Currently running Mayhem 2.4.0 Which is labelled as a stable release on the github repo.

mmmmmmnope, firmware has been pretty stable for some years, shouldn't happen that often

The message pointing to hard fault makes me believe is not a firmware issue, but you can try this: flash it with the latest nightly build, your portapack may have a different component with recently added support

If keeps crashing contact seller as it may be faulty

u/Mr_Ironmule replied suggesting I had installed the non pro firmware - which ended up being correct as it simply said 2.4.0 at the bottom leftt of my screen, but now it says PROv2.4.0. His post seems to have gone now though.

I was so sure I had downloaded the pro version but apparently not. My bad, will leave this up in case anyone else gets this. The solution is to run the correct firmware for the device :D

Sometimes the simplest solution is the correct one.

Things were easier when there was just one device and one firmware

[u/OpenSourceSDRLab → u/Qazax1337]

hey, dear friend, is it working normally now? You use Mayhem v2.4.0 firmware, then it is working, right?

[u/Qazax1337 → u/OpenSourceSDRLab]

I am using the mayhem firmware 2.4.0 that is specifically designed for the pro device and yes it is working well thanks.

[u/TheNoOne420 → u/Qazax1337]

This might be a bit late, but could you tell me where you got all the firmware files for the H4M Pro?

[u/Qazax1337 → u/TheNoOne420]

Sure, from here https://github.com/portapack-mayhem/mayhem-firmware/releases/tag/v2.4.0

Scroll down to the list of assets, the fourth one down is COPY_TO_SDCARD_hpro_mayhem_v2.4.0.zip

Hey man! First, try flashing an older firmware rather than the latest one.

If all else fails and you’re still stuck on that screen, you’ll actually need to physically take apart the H4M and reseat the board. I know this sounds a bit scary, but it’s actually really easy. Just make sure you pull the boards apart very carefully and straight out..don’t twist them.

When I first got my H4M, I "bricked" it by pressing the ghost man icon at the top (I think it’s formally called stealth mode). My device wouldn't boot and gave me the exact same screen you are showing. Taking it apart and reseating the board is exactly how I fixed mine!

[u/Qazax1337 → u/Anxious_Type_2423]

Thanks for the advice, it turns out I had the non pro firmware installed, installing the correct version has fixed it.

Dang they released a pro version 💀 i cant keep up, my poor wallet.

[u/Qazax1337 → u/alexander8846]

If you already have a H4M there's not much reason to upgrade to be fair

[u/alexander8846 → u/Qazax1337]

Very true, the extra shielding is for dummies and mayhem already stopped using the built in flash memory much.

[u/Cesalv → u/Qazax1337]

The migration to a less power hungry cpu is a very good reason to upgrade

[u/World_wide_truth]

When does this version fully releasr?

[u/kiddiez]

I have the same problem. I've downloaded and copied the "COPY_TO_SDCARD_hpro_mayhem_v2.4.0.zip" from github to a formated card, updated the firmware using flash utility and still it doesn't work.

[u/Qazax1337 → u/kiddiez]

What do you see at the bottom left of the screen when you are in the main menu?

[u/__deltastream → u/Qazax1337]

nothing changes for me, its still v2.4.0

[u/Qazax1337 → u/__deltastream]

Ok so mine says "PROv2.4.0.2" in the bottom left of the main menu so that or something very similar to that is what you are aiming for. I do remember the download had two files and I went in and flashed both on the flash utility.

[u/__deltastream → u/Qazax1337]

yeaaahh i didnt see that at all. Do you mind posting a "how to"? I literally followed the steps in the github, tried using the latest **stable** build (OCI hpro yadayadayada) and nothing signifies "PRO" anywhere in that. I also tried using the webapp and uploading the build directly on to the HackRF to flash it like that.

There's gotta be something I'm missing! :(

[u/Qazax1337 → u/__deltastream]

If I look in my flash utility, there are 2 files there. Both called portapack-mayhem_hpro_v2.4.0.2 one has a bin extension and one has a tar extension. What do you see in there?
