Hi! I updated my x470 Taichi from V 3.60 to 10.10. After flashing and restart, my system is stuck in a boot loop. I already had cleared cmos ram, but no success. So what can I do? |

3.6 to 10.10 appears a long jump to me. If so, was there supposed to be any Bridge BIOS in between? Please check the documentation. Switch off mains, remove the power chord from PSU, disconnect all storage drives (SSD/HDD etc) and long press Power On button on the cabinet for 40 seconds and retry. Check if it works now. |

What is a bridge bios? Never heart of it. PC does not work with or without drives, even Dr. Debug shows is off. |

Sometimes the BIOS update page on the vendor support site says that after an x version, before you go to z there's y in between that must be first flashed before jumping to z. e.g. you are say on v4.1 and the latest is v8.2 but there's a Bridge v5.1 in between that must be flashed before you go straight to 8.2 But without knowing the exact board model, i can't comment if there was any Bridge bios applicable. You need to check the support section for your specific model on ASRock site. The long press power button when mains is Off sometimes clears any static on the board that is preventing boot. Not too sure if you tried that. |

| One more thing..does your board support BIOS flashback option? BIOS Flashback is a feature on some motherboards that allows you to update the BIOS without CPU or RAM etc or even if the system won't boot |

Also pls. note BIOS also depends on CPU and GPU used. If the MoBo is the X470 Taichi I would suggest to try flashin with 5.10 ------------- Retired IT Specialist |

As I said before: ASRock X470 Taichi. P2.00 seems to be a bridge version. https://www.asrock.com/mb/AMD/X470%20Taichi/index.de.asp#BIOS" rel="nofollow - https://www.asrock.com/mb/AMD/X470%20Taichi/index.de.asp#BIOS No Flashback, but I tried with usb stick in USB1. CPU is 3700x |

That one is ancient and it was a bridge bios from 1.90 to higher. Your bios 3.60 is already higher than 2.20. So you should always go for a higher one instead of flashing back to that 2.20 as depending on your CPU might not start up again. Go for one of the 4.70 or 5.10 before flashing to one of the 10.x ones. ------------- Retired IT Specialist |

In absence of flashback BIOS update option, for some reasons it seems the board is almost bricked. Did you try the 30 second long press and hold power button on cabinet when mains supply to PSU if off? If that did not work, you may want to re-seat all discrete parts and check again else take it to a repair center. Don't say anything about BIOS update, just tell them that the system is now stuck at boot logo. |

PSU off and battery out for minutes. And there is no boot logo. |

I think you did not get me!! I am talking about the Power ON Switch on the cabinet. Turn off the PSU, remove the PSU power cord from mains supply and now long press the PowerON button on cabinet and hold it there for at least 30 seconds. This will clear any static charges on the board and overall system just in case that's responsible for this behavior. I am not taking about battery out. Battery out will reset the BIOS which you have already tried and did not work I guess. All the best. That's it from my side! |

What CPU do you have? One with iGPU? or a seperate videocard. If you have a seperate videocard the onboard hdmi port doesn't work. ------------- Retired IT Specialist |

You can flashback to a previous bios but you have to prepare a bootable usb drive with fat32 and dos, Rufus can help you with that, see the instructions provided by ASRock. I don't have a X470 Taichi board but I do have a X470 Master SLI one and I have flashed bioses when needed even a flashback but a flashback requires the old method video not required. ------------- Retired IT Specialist |

I have extra Geforce. I looked into your boards manual, says nothing about flashback. |

Its not in the manual. Look at the site with the bioses. ------------- Retired IT Specialist |

Just checked the main site and noticed they removed the instructions how to update/flashback your bios the old way. Found this with an old board but might still work https://asrock.com/support/BIOSIG.asp?cat=BIOS8" rel="nofollow - https://asrock.com/support/BIOSIG.asp?cat=BIOS8 at the bottom they mention how to do it (method2). ------------- Retired IT Specialist |

This is for MoBo's which have the flashback button at the rear I/O shield My ASRock B650M Pro RS board has one. AFAIK AM4 boards are missing this. ------------- Retired IT Specialist |

this is not flashback! How to press F6 when board is dead??? |

This you can use as a flashback. If your mobo is in a bootloop means it is still reacting to something. Otherwise I suggest contacting ASRock support direct as they might have a solution. ------------- Retired IT Specialist |
