I'm curious what the reason for wanting to downgrade. I think you lose the 'morecontrol' dev mode but should still be able to use the old dev mode (i think somewhere in this thread someone posted the steps to get into dev mode if you aren't upgraded to the newer software). That said, I would...

I looks like you have some other issues talking to the programmer, but once you get that sorted out, be sure that you have the correct capitalization on the hex file name when trying to flash. On my b20, the file is 'Control....', not 'control....'. I think some other people had this...

I did the manual SD card update on my ebay unit (copied from my 'factory-updated' B20), then flashed the microcontroller firmware to get things working correctly (post of page 57). The only issue i have noticed now is that during a full clean, right after it transfers the cleaning water to the...

I tried something like this to get better efficiency and try and get the step mash temps to hit more accurately. It was a first test run that didn't go perfectly. I 3d printed an elbow to fit into the mash inlet port and ran the hose up over the top. I used PETG which is generally regarded...

Typically, a cheap multimeter will show 0.5-2 ohms with the leads shorted (poor calibration/crappy leads). A good thermostat would be right around there when below its cutoff temp. I would expect the heater to show probably in the neighborhood of around 10 ohms if its in good shape. If its...

Definitely replace all those wires, terminals, and thermostat for good measure. Clean the heating element terminals very well before putting the new ones on. The insulating pad looks quite dark as well. Wondering if there wasn't a run away heating type event. If you can get your hands on a...

Another thought is if you go to the Google drive's repair docs I think there are images for both the b20 and b20+. You could try uploading the latest b20+ files to your brewie and trying again with one of those. There may also be some b20+ specific instructions on those files - I haven't dug...

I've only done it on a b20. I would try opening the brewie-upload-fw file itself in a text editor. They may have changed it a bit for the b+. On the b20 it basically calls the avrdude programming files with a few options and uses a config file to set the serial parameters. There may also be...

The b20+ likely has its own hex files on its SD card image. I have a feeling if you dig in the same directory you'll find analogous files (you can compare file dates and sizes as a sanity check). I doubt they changed that much of the command and control scheme (Linux image sends very basic...

after flashing the sd card i just popped it in and it booted up fine. I'd play with it for a bit like this before going on to the next stage. maybe a test brew. To fix my other issues (update the microcontroller) here are the steps that worked for me: These are windows based instructions. If...

Have the folks experiencing water measurement issues updated their sd card with a new version? I'm wondering if the water issue is related to a mismatch between the software version (sd card) and the firmware (microcontroller) version. There is an update script on the SD card image that can...

With a kill-a-watt hooked up to mine (b20) it draws just under 1500w total when a burner is on.

Gusius also has a mod to add another inlet for filtered watered for the brew side of things. This way he's not using his filtered water for the cooling circuit. Its pretty well documented, but i think some of his product links are now defunct as a result of turnover on aliexpress. If you dig...

Thanks for the reply. The thermal switch only controls three temp if it overheats and shuts down. These are automatically resettable switches (they open the circuit and then once cooled back down they close again - I'd guess bimetallic element inside). On my first unit it would get to around...

A quick update on my ebay unit: I flashed a new SD card with the Maibock (dev mode) build and used it for troubleshooting. Got everythign working and during a test brew, the preboil stage will only get to 200F. It seems that the machine will heat to 200, turn off until 199, then turn on...
