| I have an ASRock X470 Master SLI/as with a 7 2700 cpu and BIOS 3.4. I want to replace this cpu with a 7 5800XT and I know I need to update the BIOS with the 7 2700 installed first. Can I jump straight to BIOS 10.08 or newer without having to use a bridge BIOS version? If not, what steps do I need to take? Thanks. |

Using instant flash from within the UEFI (BIOS) you typically don't need to worry about what versions are needed or update order. The UEFI won't let you update to a version that requires another version first. When it scans your USB flash drive it will simply show no viable updates available if the version you have on the drive is incompatible. I typically download the latest BIOS, unzip it onto a fat32 formatted USB drive then go to instant flash in the BIOS. If it lets me update I continue with updating, if not, I go and download whatever version is needed (almost always listed as a "bridge BIOS"). In your case I don't see any bridge BIOS versions listed. Make sure to load factory defaults and reboot the system before updating to ensure a smooth update. -------------

| Thanks for the reply and sorry for the delay in responding. Updating the bios went as planned and I?™m happy to say that everything is running smoothly. I appreciate your assistance. I didn?™t think that there was a bridge bios that I had to use(I couldn?™t find one on the website), but I wanted to make absolutely sure. I was getting some conflicting results in my Internet searches. Thanks again. |

I'm on X470 master SLI with bios version 1.40, about to upgrade from 2600X to 5600G. Does the step is exactly same£ Some said that I have to go 1.90 first then few bios versions until 4.40, then I can jump to 10.60. But other said otherwise, which makes me confused  Thanks in advance! |

1.90 isn't a bridge BIOS so shouldn't be necessary. So yes, the same steps should work just fine for you too. Good luck with the upgrade -------------

Thanks for the advice! I thought the 1.90 is necessary since 3.20 up to 3.40 suggested it. Just to anticipate in case bios update failure, any methode to flash the bios without external tools£ |

Unfortunately no, BIOS flashback only became a more common feature with the 500 series. The update will typically list a previous version if it needs it. In other cases there may be "bridge" BIOS version/s that are required but these will always have "Bridge BIOS" in the description and are always x.00 BIOS versions. As with the OP, all you need is the latest version. So long as you take all the usual precautions, reset to defaults and reboot before updating, you should be just fine barring power outages/external factors that interrupt the update. If the update fails for any reason you can always check your local tech stores/ service centers and see if they could reflash it for you with an external tool. The tool is very affordable however and can be purchased off places like AliExpress or Amazon etc for likely less than the labor charge from a store. Failures are very rare however and usually result from mistakes made during the process like powering off the system (intentionally or accidentally). I have also always been paranoid about updates but, touch wood, in almost 30 years I have never had a flash fail. Good luck, let me know how it goes -------------

Hi again. The CPU just arrived. Still using 2600x, I'm able to update the bios up to version 3.50, can't go more than this. It says "Secure Flash check fail!". Here is the error message. https://imgur.com/a/sN4pHzn" rel="nofollow - https://imgur.com/a/sN4pHzn |

Make sure you are using a USB 2.0 port (top ports on the rear IO panel where you usually connect keyboard and mouse). Use the clear CMOS jumper to properly reset the BIOS then go into the BIOS and load defaults, save and exit. If that doesn't work then try downloading the next 3 BIOS versions past 3.50 and extract them all to your flash drive then try update again. The board should detect which version it wants. If that succeeds then grab the latest version and try go directly to that. As I said earlier in this thread, your board will detect BIOS versions that it is able to update to from your flash drive. It won't allow you to update to a version that requires another version first. Good luck -------------

Few days ago, I had no choice but to bring my pc to the local pc shop hoping they can help me to update the bios. Unfortunately, technician also said the "Secure Flash check fail" prevented them from either updating or downgrading the BIOS to any version

Contact ASRock Tech Support directly: https://tw.asrock.com/events/tsd.asp" rel="nofollow - https://tw.asrock.com/events/tsd.asp They should be able to help you out. That tech sadly wasn't very competent or lacked basic tools. A ROM flashing tool with a clip type connector can recover even a completely bricked BIOS. Here is a youtube video of the process that outlines the tools and steps needed: -------------
