I uploaded the ZWA-2 repeater firmware, tried to setup some routes with this repeater, but got "failed route" every time. So I wanted to change back, according docs, first step is "Install Z-Wave Controller Firmware". Hooked up the ZWA-2 to Mac, using Google Chrome. I can select the ZWA-2, but when I try to upload the firmware, I get the error message "Failed to enter bootloader mode". What to do??

correct, I installed repeater software on the ZWA-2. However, now I want to go back, so I need to install the Z-Wave controller firmware. But when I try to do this, I get the error message. (Whatever I try to upload new, in all cases I get the same error message. In all cases I do see that the installed firmware is the repearter firmware)

i have the same thing overhere, i bought it just to use it as a repeater. first i couldn't find the "5 digit" code to add it to HA, the added it without security. that worked but:
it's just doing nothing nothing, no zwave devices are using this repeater

Yes, I had the same, doing nothing. I even tried to force routes through the device, but also that failed. Now I want to use the device again in “normal “ mode, but it fails to install the controller firmware.

well, if you find out how the reverse back to the controller firmware, just tell us 🙂

@tiny sparrow @analog ruin You can force the ESP into bootloader mode by manually pulling the GPIO0 pin low by shorting it to ground.
There is an example on how to do this HERE which was in response to a similar problem.
I was reading the thread and thought that if gpio0 was exposed it would be possible and then ran into the example whilst looking for a clean photo of the pcb to see if it was exposed. If your not a hardware person it can seem a bit daunting but it is a very simple process.

👍

for the moment i hope for an update that it actually works as a repeater, that is the only reason i bought it

@oblique epoch Thanks for your reply. Unfortunally, this did not work. If manually pull GPIO0 pin low and then try to connect to Chrome to install controller firmware, Chrome now even fails to find the Serial port. If I disconnect GPIO0 again, it does discover Serial again, but now again it fails to find the bootloader.

I solved the issue, ZWA-2 is back in original ZWave USB hub mode.
I downloaded the .gbl file for "hub mode" from Github.
Connected the ZWA-2 to a Windows PC, running Tera Term.
In Tera Term, set serial port speed to 115200.
Type "bootloader" in the terminal window, ESP goes into bootloader mode, select 1 in terminal menu.
In Tera Term: File->Transfer->XModem and select the .gbl file. Upon completion of the upload, restart the ZWA-2, and done.
