Recover after a failed FW update via Internet

[DorinDXN]

If things can happen they may happen some times.

I have a MECHA test unit with 5000+ updates via Internet so far and didn't failed.

If it happens, for reasons like power OFF when updating or other Internet related causes,
the recovery needs to be done via the provided USB cable and an archive I can provide as support.


The steps are, in Windows

1) unpack the ZIP archive pass: Mecha
2) Do not connect MECHA with usb cable to PC yet
3) Launch the usb-update.bat as admin
4) Follow the instructions on the screen and enter the correct numeric options when you will be asked for

Please ask here if some instructions when running that .bat file are not clear or you need more info.

I tested the archive on Windows 7,
if some MECHA dealer will be kind enough to test it on Windows 10 as well, please let me know.

Also it will be very useful to provide some info of what went wrong in both updating and recovering,
if that happens.

Win 10 is also fine. I switched to Win 10 long time ago.

It will be of great help if you can test the support archive on Win 10.

I'll send it through PM

Thank you!

Hi,

I think I may have bricked my Mecha, I can not connect to the Mecha via Wi-fi on my iPhone as it cannot find or connect to the Mech- device to try again. Where can I download a FW update from the computer via USB.

Thanks in advance.

When start MECHA it blinks like this?

[Brendon G]

Yes, then all 5 lights show then disappear and a sound is made. Then when I go the Wi-Fi settings on the iPhone to select the network there is no Mech device to select, I have manually input the device and tried the Q Code. I get a message "unable to join the network "Mech-######"

[DorinDXN]

Sent the archive but do not use it for now.

First try this.
During the blinking, please press and hold [3] for 3 second until you hear multiple beeps.

Ok, missed this post, updated the FW before seeing the above message. After the FW update - still no Mecha network to connect, however a new networking "starting.." appeared. Tied the password for it - didn't work. then I tried the above - hold 3 during startup. then went to check network setting on iPhone - "starting.." disappeared and within 10 sec the Mecha-###### network reappeared. Connected to the Mecha device and was prompted to update FW. All is working well again. Thanks for your Help.

Hi Dorin.

123123 <Power was turned off during speed calibration.
The battery level was sufficient (about 80% or more).

After that, Mecha C1 does not work normally.

What should I do?

When the Mecha C1 is turned on normally, the battery level displayed in the last step is not displayed.

When the button is pressed, only a beep sounds and it does not work.
The "<" motor also does not work.

Hi Venti

Sent you a PM with an archive for usb recovery.

[Venti]

An error occurs when installing the driver.

[DorinDXN]

I remember you recovered MECHA via USB before, then you don't need the driver

You can use the old recover method via usb cable, the one which worked before, then update to the latest FW, as usual

[Venti]

The upgrade as pictured runs, but nothing happens in Mecha.
Running Mecha again doesn't work.
