I have a shared scooter version and i have change serial number to:
N2GEAXXXXCXXXX
The i would like to try to come back to the oryginal number that is:
N2LDCXXXXCXXXX
But then i got three beeps and can not use that number.
Can anybody know what does the three letter mean?:
GEA
LDC
It is good to know, and what is the reason i can not change this letter to oryginal, now.

Is there any way to download 'Ninebot-Flasher' without 'Windows Store'? I'm running Windows 10 LTSC to cut out all the nonsense (Candy Crush, Fakebook, etc) that 'Pro' has, so I don't have 'Windows Store'.

What is it that actually prevents changing of the serial number? Does upgrading to a newer DRV version blow a 'fuse' in the firmware that prevents future changes? Somehow, I think with the XiaoFlasher, I managed to change the serial number from a 'N2LUL' to a 'N2LUK', but it no longer allows the change, regardless of BLE or DRV version - right now my DRV is 5.5.1 (custom) with all registers allowing write, and BLE is 1.0.6 - the oldest that was in the 'IAP Stuff v6' file that was linked in the 'Ninebot IAP guide - how to flash your scooter with a cable' post.

I have 2 years now a ES4.

The internal battery created problems and I open to create a new battery.
Now the internal battery is without BMS.
I created a new Custom Firmware from https://esx.cfw.sh/classic using the ES4 1.5.1 with the StealthMode activated, just to not check for BMS.
After flashing, with the ESx firmware code: sjvpfguhd2 I have 2 problems:
1.- I canot flash BLE. I canot return to original DRV or BLE.
2.- I dont have speed. I press the acceleraton and nothing. I move manual the scooter and the DashBoard show the speed. NO any allarm or error.
I read here that I must change Serial Number. I changed from the original N2LBH1842C0016 to N2GSD1111C0016 but nothing happend.

Any suggestions ???


Thanks in advance,

Daniel
