Firmware | Gamesir T4 Pro Update
The fear of "bricking" the GameSir T4 Pro is largely a remnant of 2020-era firmware tools. The modern CP210x flasher is robust. By staying on factory firmware, you are potentially leaving performance on the table—higher latency, lower battery efficiency, and potential compatibility issues with future games.
In the world of multi-platform gaming controllers, the GameSir T4 Pro holds a unique spot. It’s the Swiss Army knife of gamepads—offering Hall Effect sensing joysticks (on newer revisions), programmable back buttons, RGB lighting, and compatibility across Nintendo Switch, PC (X-Input/Direct-Input), iOS, and Android.

Regarding the patch in the DeployWiz_SelectTS.vbs script, for MDT build 8443 you will have to add an extra line; in “Function ValidateTSList”, after the line that says “Dim oTS” add the following:
Dim sCmd
Dim oItem
Set oShell = createObject(“Wscript.shell”)
The two lines at the bottom are as in MDT 2013 Update 2.

Thanks for this Javier!
