Sounds like your SOIC8 clip is faulty. You can desolder and resolder the chip onto an adapter board that should have come with your CH341A, and program it like a socketed chip without extra voltage. Be careful not to lift a pad on your motherboard when desoldering.

To be serious, I thought so too! I´m now waiting for a hot air soldering device and will inform afterwards!

Thx and best regards,

cyanno

do we need to remove the CMOS battery before we attach the clip?

My asus x555lb laptop bricked and I can look up the hardware. Can I use CH341a instead of service center. My chip is gigadevice 25Q and there is a g letter on the chip.

@_haru,

could you please have a short look on the latest screenshot attached hereby. I´ve unsoldered the BIOS chip and soldered it on the adapter. In your opinion, what could be the reason: A bricked BIOS Chip or a faulty CH341A programmer?

Thx for an answer,

cyanno

@cyanno - Programmer initiation error? I've not used flashrom before, but that could be faulty CH341A, I'm sure _haru will answer shortly on this.

Also, that chip you soldered on possibly does not look like BIOS chip to me, looks too narrow (ie not squared) and may be some other IC/controller etc. Can you read what is written on it?
* Edit - Looking back at your post #91 and I think this is the issue, and probably why your clip attempts failed too! uP0104P is not a BIOS chip, this is a DC-DC converter (voltage regulator), linear regulator etc

@Lost_N_BIOS,

yes you are right. I switched the layout of the motherboard with another one. Sorry about the inconvenience and thanks for the help.

cyanno

It is still hurting to admit such a mistake regarding the mainboard. Nevertheless, can someone tell me where to find this BIOS Chip on the mainboard A55M-P33?

@cyanno - it's OK, don't feel bad, we all have to make mistakes and learn sometime! Show me image of the actual motherboard and I will show you which is BIOS chip.
Actually, I looked at MSI Stock images, the BIOS chip is here, directly above SATA ports, right beside JSPI1 header

#99 RE: Failed to read the BIOS Chip from a MSI motherboard A55M-P33 using the CH341A programmer, any suggestions? by cyanno 11.10.2019 11:14

@Lost_N_BIOS
yes, I found the BIOS chip, thanks. As you can see in the attached foto, there is not enough place to fix the SOIC8 clip, I therefore removed some of the plasic body from the nose and tried again, unfortunately again without a result. The programm is not recognizing a BIOS chip. Perhaps a last question, same question a asked by nikey22 in post 93: shall we remove the CMOS battery or is this of no concern?

Yes, you may need to shave/file down the clip some and try to make it fit. MSI Always does this, usually it's too close to PCIE slot
Maybe you are not getting good connection yet? CMOS Battery does not need removed, but board may need power connected (24+8 pin), or may need it removed.

If you have wires and a spare BIOS chip, you can use JSPI1 header, here is pinout info - Flashing BIOS chip (MX25L3205D) with CH341A progammer - can't detect chip
You will need to solder wires to spare chip, unless you have a spring loaded socket like seen in the link above.
You need to program the BIOS on the spare chip with CH341A, then connect this programmed BIOS to the JSPI1 header, then boot to BIOS and while in BIOS remove the connected chip from the JSPI1 header and reflash BIOS from M-Flash

@Lost_N_BIOS,
a very helpfull information. Now I need some time, for safety I ordered another CH341A programmer and also a cable suitable for a connection between the JSP1 header and the CH341A:

Hope that this time it will be succesfull and will report later on (which could be about one month).

#102 Need help for flashing Intel motherboard by Prasanth 12.10.2019 18:58

Hi All, I am very new here and also flashing bios.
I have two doubts to share, It will be very helpful if anyone can support.

1) I would like to flash my Intel motherboard. I have only the ".bio" file (955 KB size) not the ".bin" file. Can I Use this ".bio" file to flash?
( My pc is very old one DG35EC)
https://downloadcenter.intel.com/downloa...8?product=34689

2) Did the device and software support the chip in the image, and is it the correct bios chip?

@cyanno - very nice, looks like reports are good for this cable working. I've never seen flash possible like that, usually needs to be pre-programmed chip on other end of cable to JSPI1 and BIOS boots directly from this, but sounds like it works this way somehow. Look forward to hearing how it goes

@Prasanth - you cannot flash .BIO files from Intel with programmer. To fix your board you need to dump the current BIOS contents, make sure someone checks to be sure they are valid BIOS contents and not corrupted dump, then you can pull serial or MAC out.
Then you need another dump from same system, put your details back into it and then re-program back in.

That looks like correct chip. What is the problem with this system, are you recovering it from bad BIOS flash or something like that?

#104 RE: Need help for flashing Intel motherboard by _haru 13.10.2019 02:39

Another option is to use the Recovery BIOS method described on the site you linked.

#105 RE: Need help for flashing Intel motherboard by Prasanth 13.10.2019 09:30

@Lost_N_BIOS

Thank you for your quick reply,
I will try to explain the exact problem. The first thing is my system is working fine without any issue, the only problem is I can't update my bios.

My system is pretty old ( Over 10 years ). Each time I try to update my bios I will get the error message please check the below screens.


I tried to update with bootable USB, and find out my bios id is blank.


I also tried to update with recovery, which also failed.


Please see how my bios information displaying in the bios, system information and CPU-Z





After some research, I find this video. In the video, he is flashing the bios chip with the ".bio" file. But using different programming tools and software.
https://www.youtube.com/watch?v=ENchKl3a1L0

Then I find out CH341A after lots of research.
In simple words, I want to update my bios but now it is nearly impossible. So thinking about reprogramming the chip. Please also guide me if I can solve this problem without reprogramming.

Please also check the motherboard images.



Thank you so much for your time.
