[https://usermanual.wiki/MeiG-Smart-Tech ... LM750/info] is the link for the download for the SLM750 module, although it doesn't appear to tell you much. I'm still playing around with it, and am grateful for any help, assistance and advice from my fellow posters.
I just wanna get this bitch to run...
The sim card installed in this case appears to be of Chinese origin... dunno how it works here in New Zealand unless its roaming?
This looks like the same model I have, the SJ 2.5. Info I have so far:
  • Just power and serial lines - Kernel Panic
  • Power then Ground for 2 seconds - Additional Boot still Kernel Panic
  • Power then Ground for 5 seconds - DEBUG but still Kernel Panic

I don't have the SIM (decommissioned unit) but from research they should be:

The SLM750 actually runs a full Linux OS, they're somewhat available publicly. But the specific software for programming them does not appear to be.

Hello, i have a full boot.

Could you share how you managed to get a full boot?
As far as I know there are two ways:
1. As written in service manual with magnet, but then you have to have a working SIM, which would mean you have a stolen (not decomissioned) scooter.
2. Other way is to enter "Debug" mode, which is enabled when certain "load" is present on UART lines. I cant remember which one, but either CH340 or CP2102 adapter was recognized as a debug probe.
Option 2 ... My scooter is bought - out of service.
You do not need a SIM card to fully load modem. I used the DEBUG port with the CH340 converter, that's all.
Now I'm rebuilt with another controller.
