Does anyone know how to brush firmware for cluster
 

I saw someone say that different versions of clusters can firmware each other

like normal brz cluster brush STI's firmware normal gt86 brush GR version firmware
I can't find any information for it . The only guy who can do this want 1200rmb(aroud 170 usd ) to do this and he quit already

so hope someone can tell me something about this . because my cluster is RHD and my car is LHD （2015 brz swap 2017 cluster）. when i open the left door , the cluster shows the right door is opening. This makes me feel very uncomfortable。

（sry for my english , its not my mother language）

兄弟，要刷挺麻烦的，可以考虑卖给我。

Hi bro, not a bot. He's from mainland China, so I assume he speaks better Chinese.

He will need to desolder the old eeprom chip & rewrite with a eeprom programmer & resolder back it. I just suggest him to sell the RHD cluster to me and get a LHD one instead since I was looking for a RHD cluster :)
