Asus Prime z370-p bios update.

[thekalu1989]

Alright, bought a prime z370-p motherboard for my custom project and all was working fine until i decided to update it from bios version 2801 to latest one (3004 i think) to support windows 11.Loaded bios flash file to usb flash after i formatted to 32, entered bios and used ez flash.Watched how the update was going and no error, i used a g5400 cpu  and after restart i've received no signal and mobo restarting continuosly after 5 seconds with no video signal.

Ordered a CH341A programmer, did all the steps and now it doesn't start/stop and goes continuosly but the same issue i have no video signal and i tried both integrated and dedicated video card.

Note: CLTR reset and CMOS(battery removel).

Hello, @thekalu1989 

Considering the situation you've explained, if you've followed all the steps in [Motherboard/Desktop] ASUS EZ Flash 3 - Introduction and still cannot complete the BIOS update, we suggest contacting your retailer or ASUS official service center for additional assistance or repair.

Thank you.

My retailer does not exist anymore and the the bill i lost it because was bought in 2019, the update process is going well what i do not understand is why with g5400 post going on a loop with no image and with i3-8100 does not stop and still no image.

Motherboard serial:  HCM0AB146***

Hello, @thekalu1989 

Due to the sensitivity of personal information, we advise against disclosing your product serial number in public comments.
Therefore, I've helped obscure the last three characters.
Since your motherboard is already out of warranty, it may be ineligible for an RMA request.
We recommend referring to the troubleshooting steps outlined in [Motherboard] Troubleshooting - No Power/No Boot/No Display to try isolating any potential issues.

Thank you.

Update: the bios chip is using 2.7 to 3.2 volts, the programmer 5v...so i fried the chip.

 

This is my first attempt to do an bios reprogramming so i have to be more careful next tine and do some documentation before.

Ordered the original chip and now i will try again.
