Hi Joy,

Many persons seems to have a problem with this last firmware.
Especially with the sound volume : when start the amp the volume is on defaut volume but when trying to change it, the sound become imediately at maximum or at zero.
The only way to solve this is to make a factory reset from the app, but the issu still coming back every day.

R.B.

Hello Joy,

After the Update, I have to do a factoryreset to be able to listen via Bluetooth.

After the next powercircle, I can connect to the device but no music is playing. Only after a factory reset, I can connect AND listen to music - until I switch the device off and on again.

Furthermore the web interface is not working and therefore it is impossible to connect to my own wifi. So basically with the update, the thing is bricked and not usable.

Is there a fix for this or a possibility to downgrade to the last firmware? The last one worked like a charm. I’m using the amp V4

Cheers Simon

Hey @Joy,

Will there be a possible downgrade? Like I said before, the device is now literally a brick.

Hi Simon, could you please help to try this version? And see if the problem fixed.

Hey,
this beta fixed basically all my issues. Thank you. Do I have to set the OTA mirror back to the default somehow?

Cheers

Hello,
I have no idea why there is a firmware upgrade because every time there is my device becomes a brick. I just thought I was purchasing a device that would work. If it works then stop trying to fix it.
This is the third time it stopped working for me. First time I found a step by step solution. Second time, after a few days it started working. Now, I have know idea what I’m supposed to do even with what you told SimonA to do???
Very frustrated with this device and company.

Hi, I suppose you’re also suffering for the volume issue. I’m really sorry for all the mess, and have pushed the new udpates for AMPV4, and will update others soon later.
Regarding the upgrading. We keep working on upgrading firmware to fix issues and new features, maybe they’re not desired for everyone, but we’re trying to make it better. And because we’re working on a some what open board to let user customizing with many configs, and that makes the system a bit complicated for fully testing.
And, don’t feel frustrated, enjoy the pain and joy of DIY :slight_smile:

Well…I tried to reset the device to factory settings and that didn’t help. So is there any way for me to fix this with instructions or am I supposed to wait for another update?

I suspect the cause of the volume issue and maybe some other strange behaviour is that memory overflow while composing a reply message for EQ groups. Did you ever save different EQ groups with ACP tool? If so, could try reset factory on ACP tool and check. I’ve expanded this tmp buffer in firmware and also will check bundary to avoid problem.
