Dell XPS 9310 Stuck at logo Blinking 3 amber 6 white. What's Wrong? 

All windows machines have the OS license in the BIOS since the conversion to UEFI. Exceedingly rare to have anything come in that's older these days, at least for me.

​@@x8jason8x Yup. Since backup was not made, any chances of retrieving the OS license from the original BIOS and transferring it to the candidate firmware is gone. But the best way to go through this is to backup the original BIOS, then clean the ME Region from that as it has the highest percentage of working as opposed to an unverified dump from the web. In this case, more damage was actually done to the laptop and it is permanent since you cannot recover the already overwritten original BIOS firmware.

@@lazal3m The licence isnt stored in the BIOS, the identifying information, called DMI strings are), Windows reads these DMI strings and that causes Windows to activate if they find a match in the Microsoft Activation servers. All the BIOS needs is the appropriate DMI strings which usually include 3-5 values including model number and serial number programmed into them either using a DMI tool or in some cases the BIOS lets you add the values directly. I had a HP AIO come in the other day which was citing it didnt have correct DMI values (every value was blank), it needed a Model Name, Model number, machine Serial Number, a unique identifier for the model (check byte i think), and a mainboard serial number. We had 2 more of the same model in the store at the time, so we verified that both had the exact same SKU and looked in the BIOS for the unique identifier, saw they were the same on both units. I then added into the unit without any info its main unit model name, serial number, model number. I copied the check byte (i think it was called that) which was about 50 characters from one of the other units. I then after having opened its cover located the mainboard serial number printed on it which is different to the machine serial and entered that in. Once the values were accepted and the machine rebooted, the Windows 10 Home on the machine immediately activated using a digital license without troubleshooting or changing any keys. Typically so long as you have the ability to enter the DMI information into the new BIOS chip and you have the correct details to enter in, Windows activates no problem. Just depends on manufactuer if it needs a proprietary software utility or if it can be done directly in the BIOS menus. With most HPs I have found it can be done directly, but the section of the BIOS that allows it is only able to accept new values if it detects there is a value missing. Basically it tells you values are wrong or missing and offers the chance to reboot and enter a mode that allows you to enter data to those specific values. Entering wildly wrong values though tends to make it not POST without fully resetting the EC data. So if you dont know what they are, best to leave them blank until you know exactly what to type in. You have to do this every time you replace a mainboard in a system using the new digital activation system from Microsoft (basically every machine from Windows 8 onwards).

Yes all technician should know this.👍

@@MrGeneralScar thanks for explaining further! So the DMI string is the calculated product of model name & number, machine serial, mainboard serial, and check byte. This further complicates the repair process and chances are if you miss a character or typed in the wrong case, the resulting DMI might not even match anything stored in the activation server. You would have to re-program the flash chip again and do the same steps until it matches/activates successfully?

Same goes with apple phones replace the batt yourself or have a certified repair shop do it it will still fail startup boot message for the remaining life of phone cause certified apple has keys to punch into the hashes

To me it looked that the BIOS chip was blank and contain no data

hey! you're right 😀

It was already blinking amber and white?

he did mention that the battery is faulty it could of been blinking because of the battery

100%. We do this for every laptop. When laptop is handed over to big boss, he doesn't leave anything untouched.

Notice the flash process consists of 3 steps - erase, write, verify. You know the purpose of the last step.

Yes i know. If the file is verified correctly it does mean the ic will work .

Googled and always takes me to universal bios backup tool. Do you have any link for that program?

He stated in the video that the bios file he was flashing had a clean ME.

Dell XPS RAM is not replaceable, it is soldered onto the motherboard. But I do not think the issue is a faulty RAM chip.
