 > ## _**I accidentally installed my drivers the wrong way round and when I switched on the mainboard released magic smoke**_
 
-When that happens, you unfortunately have to buy new drivers because at least one and often even several die in the process :( The Trigorilla mainboard can be revived relatively easily, because in 95% of the cases only the Zener diode (5.1V 1W Z-Diode). It has the identifier **733A** which also indicates the type. Here you can now buy SMD (surface mount device), such as the [16X SMAZ5V1-13-F](https://amzn.to/2EosAZQ), or you do it like me and buy a pack of 100 of the [1N4733 glass diodes](https://amzn.to/3l45xnU), snap off the pins and simply solder them onto the board. The design is then not ideal, but they are easier to get and cheaper.;)

 The following picture shows an intact board with the diode still intact:
