Dell E5470 custom bios issue

[Calgacus]

Hi

I have a Dell E5470. I am trying to re install windows 10. I have wiped the partitions on hard drive and ran the setup. When i get to the network selection screen there is no option bypass where you normally see it down in bottom left of screen.
When you connect to wifi it goes to a custom screen that requests logging into a specific user account on a server.
It's not getting this info from the hard drive as it's wiped. I have read the bios file and attached.
Searching the bios file in hex editor results in showing a reference to the company website in the bios bin file.

I was hoping someone with the correct knowledge can remoce what ever it is thats causing it to force windows install down this path instead of a normal install.
Please advise if you need further details.

Any information on this would be appreciated

Thanks in advance

Re: Dell E5470 custom bios issue

Backup fault. Your bios region's empty.

Re: Dell E5470 custom bios issue

Ok... i will try re read the bios

Update: i am using the RT809F programmer, but its displaying message that the chip ID does not match
the bios chips is Winbond 25Q128FVSQ But this is not in the list of known chips. Autodetech sees it as a cypruss
Not sure what all this means
Any help appreciated

Maybe this time after playing with different version pf software

No, fault again.

Re: Dell E5470 custom bios issue

the re-read and verify went without any errors but i will try again, I did notice the size of the bin file at 16mb but the zipped file was only 52kb which seemed a bit low...is there a option to upload the full bin file ?

Thanks

Try manual chip selection. Do not select auto-detection.

Re: Dell E5470 custom bios issue

Appreciate your help hoaca, i am using the software that came with the programmer its not very good to be honest. I cant see the actual chip listed from the available chip options.

Can you recommend a good programming software alternative
I am using a version of ifix RT809 even the latest version of tis software does not have my chip listed, it autodetects as a cypruss 25Q128BVSQ

the actual print on the bios chip is 25Q128FVSQ

Re: Dell E5470 custom bios issue

I have re read the chip 3 times and its verified fine each time

I have renamed the bin file to zip instead of compressing it as it seems to be very small when compressed

Hope its intact this time

Thanks again

Re: Dell E5470 custom bios issue

Read about Windows autopilot.

And then install either Windows home or Linux

Your bios is not custom, don't waste time on that

Re: Dell E5470 custom bios issue

Hi Rethorical

Never used Autopilot, but have installed windows on lots of systems and never seen this issue before. So it's stumped me. See attached screen shots showing the windows installer screen that it lands on during install after i select keyboard layout etc...
There is no option to create a local account and the "I dont have internet" option is also missing from the account screen.
It cant be getting the company name from the hard drive because it's been cleaned with diskpart prior to install.
That led me to suspect the bios. So i dumped the bios file and searched for the same company name inside the bin file and found the company name located in the bin file.

I can't find anything online about this so was hoping it could simply be cleaned from the bios file to allow me to do a standard windows install

Thanks again for your reply, and further advice welcome

Are you using a sop8 clip to make your backups because they`re all corrupt ? .Post the service tag please
.

[Calgacus]

Re: Dell E5470 custom bios issue

Hi M8

yes, i have been using the clip. not had any issues with it before, but obviously its not working if even the latest read is corrupt. It verified 3 times though.

I will now de solder the chip and read it that way

Thanks for your input

appreciated.

Any thoughts on the bios containing this company name which is the same name as th login its trying to use at first log in on clean install ?

As far as i can tell its just part of a domain ,AMT settings are where its stored. I asked you for your service tag, with that we can look at your laptop configuration. Depending on the configuration you can use another dump with clean ME firmware

Re: Dell E5470 custom bios issue

Hi

sorry mist the request for the service tag m8

here you go

33579617150

in bios setting it reads FFCFQF2

thanks

My rework station is at home so i will do this task this eve

Thanks for your time

Re: Dell E5470 custom bios issue

I would erase the code from the bios dump and see what happens, just out of curiosity

Re: Dell E5470 custom bios issue

Things I have done to try to remove autopilot, the exact same thing you have right now (on lenovo).
New me + main bios, new SN and motherboard SN, new network mac, new windows installer and maybe something else. Nothing helped. Only thing I did not do, which might help, was to replace TPM chip.

As I said, install windows HOME not PRO. In that case, windows will not check if autopilot is installed because autopilot is not a part of windows home.

But if you do find a solution for this, I am all ears. Keeping clear from PRO is just a workaround sadly.

Autopilot is quite a recent thing. It was first implemented last year I think. And first autopilot laptops ended up in my hand at the end of last year I think. And some companies do unenroll from autopilot but others either forget or are too lazy to do it. Sadly microsoft has not implemented any way to unenroll for 3rd party users.

Re: Dell E5470 custom bios issue

It's around 3/4 years old so i don't think its autopilot.

It does allow booting into the AMT setting menu, by pressing CTRL P at first boot...but thats password protected also, so cant change or even browse anythng in there.

See attached fresh bios dump with the chip desoldered.

compressed zip file

Thanks again for advice on this
