B550-F Gaming Wifi no post and no flash

Vulkaros
Level 8

I'm trying to resurrect a said to be bricked Motherboard, B550-F Gaming Wifi, that does not post to bios when mounted with CPU, correctly placed and working RAMs, and a GPU, also a good working power supply. Whenever i try to Flash the Bios using an USB formated to FAT32, and correct file, it blinks 5 times then goes static LED. Is there any way i can flash this bios into the motherboard somehow? Is there a way to change the USB port needed for the USB Flashback in case the USB Port is damaged in some way? Or is the Motherboard bricked forever?

Hello @Vulkaros 

Thank you for reaching out to us.
Based on your description, may I ask if this motherboard has previously been diagnosed as failing to power on or boot?
According to steps 7 and 8 in [Motherboard] How to use USB BIOS FlashBack™?, after pressing the flashback button, the indicator light will start flashing and the BIOS update will begin, turning off once the update is complete.
The time required for the BIOS update can vary depending on the motherboard model and the version gap you are updating.

Regarding the inability to boot or display, if the system still fails to boot with minimal hardware setup: only a CPU that supports integrated graphics, a single RAM stick in the DIMM_B2 slot, and power cable connected to the PSU, we recommend considering sending the motherboard for repair to receive further hardware diagnostics.

Please refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display if needed.

Thank you.

As the local holiday is ongoing, there may be further delays in responses.
We appreciate your patience in advance.

Hello. I really don't know. We got this Motherboard for a build and it didn't flash (5 Light Flicks then staying on forever), and never posted to BIOS, so we discarded it and got new one right away. It was there until i picked it up to try solve its problem. 
I've tried the Ram Sticks, ive tried several GPUs and CPUs, tried also several Power Supply, varying from 650W to 1000W, every single one Gold Certificate. It simply doesn't post. Tried flashing with only Power Supply, tried flashing with rams only, GPU only, CPU only (also Power, ofc), and with everything built like in a normal PC. Tried flashing in all USB Ports and also USB Ports of a working case. Nothing seems to work. This Motherboard doesn't flash, or even boot to BIOs.
Also i've tried, not successfully, bios updates flashing for different motherboard versions, like the normal B550-F Gaming, and the Wi-Fi II.
