Hi all
I asked for bios dump for dell latitude 3520 bios locked
and onizzbox told me to dump my bios and give him to be unlocked.
He unlocked the bios but he put password on bios dump unlocked file. I don't
understand that situation. The rule on this forum is all action is free and don't need
to pay something. So I resume, if onizzbox want that I pay his action, why He don't tell
that. I know also ho to unlock bios but I don't have another bios dump for this laptop.
Wait for the reflexion for this guy

You ask for help, now you claim to know how to solve???
The file was posted by you in the follow-up #3, how can you not have the file anymore??? Dell BIOS should be unique to each device, it should NEVER be shared, people with technical skills know this!!!

Unfortunately it's hard to know who we can help... Not even a simple thank you or feedback.

I think there are some privacy implications of publicly disclosing your Service Tag.

The Service Tag uniquely identifies the device (not only the configuration).

1. On the https://www.dell.com/support site, anyone can find out the hardware configuration, the software initially included with the device, warranty information, date of purchase and the country of purchase of the device.

2. On https://www.dell.com/support/inciden...4/email/stolen, someone could falsely report the device as stolen, possibly causing some minor trouble when the real owner calls Dell for support.

3. Dell recommends not to share/post service tag number on public forums (https://www.dell.com/community/Lapto...t/true#M651153). In fact, if you post it on Dell forums, it will be removed by the moderators (search for "Service tag removed per privacy policy").

You also included your contact detaiils which is against the site rules. Password protecting files is against the site rules.

The service tag can be found by searching through the bios dump with a hex editor.It saves time if members post the service tag,it can be entered at the dell support site to find the right bios.The service tag given is generally from the case, the service tag in the bios dump does not always match.When the service tag does not match we know that the member or another service has flashed the wrong bios,sometimes from a completely different model, or has the wrong ME firmware version, and so on.

Posting the service tag does have some privacy implications i suppose.

It's not me saying, it's the manufacturer himself!!

PM exists on forums to provide privacy between members. Although I didn't find it in the forum terms and conditions. Protecting a file due to the manufacturer's recommendations, I don't think it's a mistake. But that's ok, rules are rules... Next time, I'll send the file in PM, without password, directly to the requester.

Hi onizzbox
thank you for your help. As SMDFlea said, in this forum
the rule is don't crypt the file. I've asked on forum to remove password
and everytime I'll get file without password.
So, I'll test this file and tell you the result.
Thanks

Hi onizzbox
I'd tested the modified dump but this is what happen:
the laptop boot 3 times , the light screen is on but no display and it shut off.
It seems that the procedure of reseting the bios is executed but at the end it
shut of abnormaly.
what you suggested to do. You proposed me another dump.

Joke! The bios used is the original, your problem is another.

Hi onizzbox
this laptop had no problem with the original dump
except the bios is locked with 8fc8 suffix
I don't know why your dump don't work. I haven't desolder
the eeprom. Maybe when I programm with the eeprom on the board, the content
was corrupted

Review the burning process, your BIOS is perfect.
