 In the case of a bricked ESC/Controller/Control Board, STLinking can save the controller from needing to be replaced in some instances.
-For this process you will need:
+{{ STLink Materials List }}
-* Windows computer
+For the Ninebot ESX Series/[[Ninebot SNSC 1.0|SNSC 1.0]], use the guide at: [[STLink Ninebot ESX ESC]].
-* STLink (Decent quality clones will work)
+==Identify Which ESC Generation You Have==
-* Tools to disassemble the scooter and access the ESC
+Check out the difference between the [[Ninebot Max ESC Generations]] and use the steps below depending on which one you have.
-* Dupont male/female jumper cables
+There are 3 different board layouts.
-This process can be dangerous if done incorrectly so take caution when performing these steps and make sure you use a computer you are comfortable possibly destroying.

-===Accessing the ESC===
-Start by removing the 18 Security Torx T-15 screws on the bottom.
-[[File: NinebotMaxBottomScrewLocations.jpg|thumb|center|400px|The locations of the 18 screws.]]
-Using an M4 Allen/Hex wrench or bit, remove the two screws holding the ESC in place.
-[[File: NinebotMaxESCLocations.jpg|thumb|center|400px|The ESC after being removed.]]
-Carefully unplug each of the connectors.
-You may need to scrape more rubber potting compound away from some of the connectors in order to unplug them.
-===Accessing The Pins===
-Carefully scrape away the potting compound, making sure not to remove any of the small surface mount components.
-[[File: NinebotMaxDebugPins.jpg|thumb|center|400px|Be very careful not to damage any of the smaller SMD components.]]
-==Software==
-Download [https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stsw-link004.html#get-software STM32 STLink Utility] from the ST website.
-Scroll down and click "Get Software" and enter your email to receive a download link.
-Install it and open it.
-==Flashing==
-Connect the STLink to the ESC according to the diagram below.
-The BMS port red and black wires can also be connected to provide power instead of using the BMS connector and ground point.
-[[File:NinebotMaxESCSTLinkPinout.jpg|center|thumb|400px]]
-*Open STM32 ST-Link utility and connect to the ESC using the plug at the top
-*Press Target->Connect from the top menu
-[[File:StLinkUtilityNinebotMax.png|thumb|center|400px|No error messages about "Unable to connect to target" should display.]]
-*Press "Open File" and open [[File:NinebotMAX FULLESC126.bin]].
-[[File:StLinkUtilityNinebotMaxESCProgram.png|thumb|center|400px|At this point a red LED should light up on the board.]]
