[Twiz O'meter/BigToM/ToM+] Update to firmware 2.4

You can short the steps, as follow:
1. Update Display OTA 1.7 -> 2.4 (will stay black after that)
2. Update Blackbox OTA 1.8 -> 2.4

Hm. I thought Display OTA does not work prior to 2.3 as it was a new feature then.
Therefore I thought I need to update to Blackbox 2.3 first to enable Display OTA

Opss. You are right!
If fw 1.7 haven't the OTA update for the display (I don't remember), you have to update first to 2.3
Sorry for the wrong information.

So:
1. Update Blackbox OTA 1.8 -> 2.3
2. Update Display OTA 2.3 -> 2.4 (it will stay black after that)
3. Update BlackBox OTA 2.3 -> 2.4

Well…

1. Update Blackbox OTA 1.8 -> 2.3
2. Update Display OTA 17 -> 2.4 (it will stay black after that)
3. Update BlackBox OTA 2.3 -> 2.4


worked like a charm, Display OTA 77 Seconds, the Blackbox updates where like 1 second each.


But than I had the idea to copy the TwizyCfg.ino.bin to the special partition to test higher recup. That also took only about a second and the ToM went black right away.
Unfortunately I have now no access to the ToM anymore. The ToM is not connected to any network anymore and I do not see any Twizy-cfg AP . Power off/on does nothing.

So I guess I bricked my ToM somehow.

No.... it's nearly impossible to kill the ToM!
Give me in private your SN (look at the label on the box) and I'll send you the instructions to revive your ToM.

No, probably not.
ToM is (nearly) "unbrickable".

In worst case you need to flash by usb cable.

Update:
Fabio was one minute faster than me!

And you know it quiet well!

Done.

Well - I already thought I may be able to flash it. Installed driver and right now installing esptool on my Mac.

But wanted to hear what the experts (thus you two ) think the best way to do right now may be.

Basically the FW2.4 will still be there, I would need to tell the ToM to boot from the right partition I guess.

You'll have to flash.
Only the main fw won't be enough.
I'll send later all the needed files.
It's easy, don't worry.
