Hi! I am trying to use the scripts in esc-tools to read the 4in1 esc for the voxl2mini 
and it seems like only 1 of the 4 escs is detected:

```
voxl2-mini:/usr/share/modalai/voxl-esc-tools$ python3 voxl-esc-verify-params.py 
Detected Python version : 3.6.9 (default, Mar 10 2023, 16:46:00)

```

@tiralonghipol 

Sorry about that!

Please check the recovery procedure i just described in another thread (bottom) : https://forum.modalai.com/topic/2897/voxl-mini-4in1-esc-and-voxl-2/8

@Alex-Kushleyev  thank you for the fast reply!

I (apparenmtly) solved the issue after upgrading everything to latest version and uploading the correct params for m0129 v3 from my laptop
interestingly the mini2 detects the complement of what my usb-uart cable detecs

but yes thank you for the tools, otherwise I had no idea how to recover a bricked 4in1 lol

@tiralonghipol , great to hear! if you have this issue again, you should be able to recover the ESC using the steps I described.
