Pico C 'Failed Update' Error

[RoundRockBrewer]

Have a brand-new Pico C connected to my Picobrew server. It connects goes to update and gives a 'failed update' error message. I can't proceed past this error. I have looked everywhere online I can think of for a solution, for two days, and can't find anything about it. Can someone please help me out with this?

I believe you need to add the machine UID to the config.yaml (/devices) since the server has no way to know whether the device is a C or a Pro/S (which have different firmware).

[RoundRockBrewer]

Makes sense. Where do I find the config.yaml to add the machine UID? And where do I find the machine's UID?

Thank You Bucko!

[BuckoWA]

The machine ID can be found by starting the machine in Service Menu. To do that, press and hold the dial knob on the front and then power on the machine. Press the knob once and the machine ID will show up.

The easiest way to add the machine ID to the config file is through the server's devices page. In the upper right hand corner, under System, pull down and select Devices. Then press the green + Add Device. Select Pico C, add the machine ID, and give it a name you'd like and press Save. This will add to the file. You can also manually add to the config.yaml file in the picobrew_pico directory, but that requires using a linux text editor to add it. Much easier through the server itself.

Good luck.

Well that worked for the update. Showed updating, restarting, showed garbage on the display then went blank. That's all it does now. Is my machine now bricked? Any suggestions?

[BuckoWA]

Hmmm... Haven't seen that occur. Are you able to boot the machine into the Service mode again? If so, you can factory reset in that menu. Exit Service menu and try again.?

[RoundRockBrewer]

I can't see anything but garbage on the screen at startup then the screen goes black and never comes back. Would upload a video, but don't think it will help beyond my explanation. If the control knob/button are still working but I just can't see what it's displaying, can you walk me through it 'in the blind'? Worth a shot I guess, otherwise I think I've probably got an expensive brand-new boat anchor.

Here's how to do the Factory reset, although I'm a little skeptical about this working in the blind as you say.

Power up in the Service menu by pressing and holding the knob and then pressing the power switch. Wait 5-10 seconds.
Press the knob 3 times.
Scroll knob right 5 times.
Press the button.
Scroll knob right 1 time.
Press the button.

Hope this works.

Well that did something. It makes some crazy loud noises like an arm is rotating for 10-15 seconds then just hums continuously like a pump motor or something is running. Wonder how a firmware update could cause this to happen and what the solution is to fix it?

[BuckoWA]

Maybe the file was corrupted during the download. Let's see if anybody else chimes in here. Otherwise, I may be able to salvage a PCB from one of my units I'm using for parts and send it to you.

You can program the firmware via USB serial if you take the LCD off, if needed.. not near a PC at the moment

[RoundRockBrewer]

I can certainly do that if I have the correct firmware and know where to plug the USB in. I'm in no rush at this point. Just want to get her up and running. Thank you!

I believe scroll knob left vs scroll knob right might end the prompt at a different utility. The pumping and sounds heard sound like there was a test session, rinse or other recirculation utility triggered perhaps?

Are you sure you have a Pico C vs Pico S/Pro? I ask cause it has been reported that if the wrong device type firmware is loaded the device has either an oversized or undersized display. Maybe you have the oversized display where you can't really read or see what is intended to be shown due to the bevel of the display board?

[RoundRockBrewer]

Yes. Here's a pic of the back placard.

Good point. Scroll right in the directions there. Sorry - should have specified. Here's how to do the Factory reset, although I'm a little skeptical about this working in the blind as you say.
