Dell OptiPlex 5060 - orange power led blink - 1 long 2 short

You should measure the circuit to the SPI when CMOS battery is present.
This is a 1,8v IC if not mistaken…not reading upper posts… the PSU should be 3,3v stand-by power and this always the last thing to try. Theres the risk of damage to the CH341 or IC.
Many Macs and pc laptop boards require PSU on but this is desktop motherboard with 3,3v CMOS and it all depends on the motherboard circuit design.
You should confim this with that user from the thread i previously linked.
He did tried with PSU and no results.
He confirmed the connection established after post #15

Even with a brand new set as you just build, theres still the “tiny” issue of correct contact, it may look correctly connected… very common on this clips.

Do please keep in mind that all my guidance is given by general knowledge and i im not going to confirm it personally all this details, every time a user asks help on a subject… i would not live my personal and professional life if i were to loose time to this forum or any other forum with such technical details to each user/issue, im sure that you know and understand what i mean…
Regards.

EDIT: Ok when the IC is 2,7v to 3,6v.

Thank you very much for following my attempts to access the IC W25Q256JVFQ.

As the CH341A operates with 3.3 V, there is no risk of damaging the IC, ok? Or am I wrong?
I’ll keep trying to access the IC. I will report here.

Hey guys

I couldn’t read the IC soldered on the motherboard.
To test I bought 2 chips 25Q256JVFQ (same as on the motherboard) to try to read.
On the first try, the CH341a detected and read the IC normally.
Now I’m going to try to unsolder the IC from the motherboard to try to make the backup.
If it works I would like to have your help to try to record the new one, because it seems to me a very complicated task.
Thanks

Same post as 3 days ago? Read the chip and attach the dump of your chip to a post.

Read the chip at least twice, you need 2 a 100% identical reads to be sure that they are correct. Check the structure with UEFIToolNE.

Hello
I removed the chip from the motherboard. I read and wrote 2 files.
File 1: dell_5060-1.bin
Hash MD5: 7e69d050a4d1ed04ee30db278ef374d7

File 2: dell_5060-2.bin
Hash MD5: 7e69d050a4d1ed04ee30db278ef374d7

I can’t attach the dump file (32768MB).

Good to hear that it seemed to work!

@Keppler

I can’t attach the dump file (32768MB).

That’s tragic. Should normally have acceptable size zipped? Heard of splitted zip archives or file hoster services?

[Keppler]

Sorry, I forgot to try to upload the compressed file.

Thank you for being patient in helping. I have no experience performing this procedure.

The firmware looks fine, one slight difference to stock I can’t explain in code areas:

Otherwise both NVRAM filled with a lot of a little ‘rare’ identical entries in the end, but nothing really obvious.

Try that file:
dell_5060-1_natbreg_ME.zip (9.3 MB)

That’s your firmware with a stock bios, DVAR block transfered (0x1081000, size 0x10000), ME clean / freshly initialized according to

[Guide] Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization

Guide-How To: Clean Dumped Intel Engine (CS)ME/(CS)TXE Regions with Data Initialization Last Updated: 2020-07-22 This guide is relevant to those who need to clean the DATA section of an Engine (CSME, ME, CSTXE, TXE) Region, which is part of a dumped SPI/BIOS image, in order to flash the latter on a different machine of the same OEM model. It is not meant as a guide on how to completely transform a dumped Engine region into a stock Intel-provided one. Although the guide can be used for that some…

After programming dump the chip again in a separate process, save the dumped content with another name, and compare it to the original file. They should be a 100% identical.

(If this works and in case you should have to work again on the firmware- it’s the folder with “2 CombineBiosName…”)

[Keppler]

Thank you very much
I recorded the file you sent in a new chip and soldered it on the motherboard. Then post the result here.

Hey guys,

After several attempts the board does not work. I come to the conclusion that it must be a hardware problem. Electronics.

I thank everyone who helped me. I learned a little more from you.

Thank you so much.

Thanks for the feedback!
