I have been changing some bios settings and disabled USB 3 option. This now prevent’s me from using USB keyboard at post. I can use it If I boot the NAS using an ssd with windows on it. I tried restting the BIOS but removing the battery does not work. I found a post where it says that only flashing rhe bios solves this. I’ve also found a way to do this but I can’t find the file anywhere. Can you provide me the BIOS file so I can fix may NAS?
Thank you for your help in advance.
Hello
You’ll need to contact QNAP Support to get a Bios for your NAS.
Pls look How to flash BIOS if USB function is disable - QNAPedia
BIOS file : http://download.qnap.com/Storage/tsd/bios/HS-251_QW57AR09.zip
Thank you. Will test this out today. And the bios download link is for the HS-251+ NAS correct?
Yes.
Note, however, that during the firmware re-flash procedure, the firmware of the HS-251+ is different from that of the HS-251. Firmware Recovery - QNAPedia
The firmware recovery I already did some time ago and should not be neccesary. I just need the NAS to recognize the internal USB storage where the Qnap OS is booted from to be operational again 
Check with QNAP support if there is a reset setting (jumper or testpoints to bridge) for the BIOS.
Otherwise leave out the battery for several days (and power of course) and try again
The bios zip file is missing the GO.BAT and probably some other tool to flash the bios. Not sure coz the image is so smal but looks like AFDOS.exe or something like that. Everything else I have already prepared. Do you perhapse know where I could get the correct tool?
That flashrom file looks like it’s a binary but I don’t know how to use it. Just
flashrom QW57AR09.BIN
perhaps?
I tried this by booting to ubuntu and installing: sudo apt install flashrom - which looks like the correct flasher to use. And I ran
sudo flashrom --programmer internal --verify QW57AR09.BIN
and I got a response that the biso is not valid. When I extractd the bios and tried against that it said it’s valid. So now I’m not sure this is the correct bios for the HS 251+?
I kinda confirmed that the bios was walid: QNAP 2-Bay Turbo NAS HS 251+ mit zwei 2TB SATA HDD-Festplatten in Nordrhein-Westfalen - Troisdorf | Festplatten & Laufwerke gebraucht kaufen | kleinanzeigen.de
here this person said he had that saame version on HS-251+ and it fixed the USB. I ran sudo flashrom --programmer internal --write QW57AR09.BIN and it flashed sucesfully.
Now I’m left with one issue - why I disable USB 3 to start with: the ports for USB 3 don’t appear to be working any more. What could be the issue? I know they worked when I started but then just randomly stopped after I booted the device a couple of times. Any ideas?
I’m also in contact with them to see if there is some other resolution to this issue. Thanks for the suggestion.
