Either someone is playing with you (i.e. someone at home controlling amp remotely), or you have defective unit. If i were you, i wouldn’t try to downgrade firmware, but instead i would listen to Arcam’s advice and send it back to them to get it properly tested and fixed. Latest firmwares are really solid, with only some minor glitches in beta releases some of us are testing. Never heard about it changing sound from great to awful. Of course, i also have days when it sounds worse, but it’s more psycho-acoustics than amp itself. ---

I would have thought the same thing if it wasn’t for that noone has access to it remotely and the source was my turntable (if it was streaming there could have been a glitch elsewhere). You’re right - it is most likely a defective unit, but I figured I’d still follow their last resort advise and see what happens when starting from scratch. I vaguely recall it behaving a bit odd when doing an automatic update - the very first one I think, after I got it in the summer of 2020. Then again that was a long time ago, so perhaps it doesn’t matter. I’m a bit reluctant to drop a $3,000 unit in the mail but that’s probably what it’s gonna come to. I guess as it is now it’s pretty useless anyway, so… ---

Have you actually tried resetting it to factory defaults (System reset AND NET reset)? To be honest i don’t think downgrading to 521 firmware was what they meant by “starting from scratch”. What i would try instead, as a last resort, would be to re-flash latest firmware, perform full reset (system and net) and check if it helped. I don’t know if you did reset after automatic update, but if not, this might be your issue. There has been significant changes in the firmwares, and for some intermediate versions reset was Arcam’s requirement. Might be you’re just experiencing issues caused by those changes performed without reset. So re-flash, reset and try from there. If it works, great, if not - send it to Arcam. ---

I have tried everything I possibly can (I think?), aside from reverting to the firmware it came with. Net and system reset after each update,.except for the very first automatic one - since it doesn’t say anything about updates in the manual I had no idea that needed to be done the first time an update was made. I have tried to reflash the latest firmware but it gives “update failed”, which I figured was because it already has the latest firmware. I did successfully install the new beta firmware today and am currently trying it out, after doing a net and system reset, and with max volume set very low… I have had long conversations and discussions with Arcam about this unit, so yes, starting with the first firmware is what they meant… ---

This worked out! I think the trick was in filename and lack of feedback from the amp that it actually started reprogramming. **Attention!** When I left the amp turned on after step 8 and went to kitchen to cook the breakfast, the amp rebooted and started playing smth on extremely high volume (I think around 50) and then turned off in a couple of seconds (possibly after overload protection was activated). So I think that step 0 of the manual should be “ **unplug the speaker cables** ” ---

In this link below there is all the previous firmware’s and I have now added a pdf with instructions from Arcam on how to do a service reset.

Hi Paul, Although I have followed the recovery steps, when I turn the amp on while pressing the service button, it says “net updating” right away and then “net update fail”. And then the messsege disappears, there is no firmware change. My main problem is that ARC ver is 0.0 and ARC connection does not work. I also tried ARC recovery but nothing changed. Please help…… ---

I would contact Arcam in that case [Previous page](https://arcam.discourse.group/t/how-to-do-a-full-reset-and-reload-of-firmware/293.md?page=1)
