  I have used the above online keygen to downgrade my buggy v3 firmware on my T12 Soldering iron that I purchased from AliExpress
  
  Firmware from links on this site : - https://mysku.ru/blog/taobao/48640.html
  
  If anybody wants any more details on how to do the upgrade I'll post up further details.
  
  The photos are of my pcb, but the firmware is compatible with another pcb.

• Hi there. If it isn't too late to remember, then please post here more details about how to do this process. As some of us have the v3.0 board and would like to change / improve the firmware. Thank you.
