Latest is p1.0-109-g3bcd922 by @flashrom. It definitely works. I attached all 3 versions to an earlier post:

I recommend using the latest version by @flashrom from #214 linked above but if anyone needs it I am attaching a single ZIP with all the 3 versions that were posted in this thread so far: p1.0-109-g3bcd922 (newest), 0.9.9-97-g29333a0 (previous), and v0.9.9-r1954 (oldest).

Must be something about your local setup.

• Is the driver installed (need to go around signature enforcement)?
• Can you see it in Device Manager?
• Did you connect to a separate USB port, not through any hub?
• Is the SPI flash chip properly connected (it'd also show this error if it weren't)?
• From my experience the last thing is the most likely reason but I've also never got this kind of error message like you quoted, so if it's not any of the 3 things above, then maybe this discussion will help: https://github.com/libusb/libusb/issues/...mment-368224551

• driver installed
• I see in Device Manager
• connect to direct USB (no HUB)
• SPI flash chip properly connected - Windows CH341A v1.34 programmer detect and work OK

What exactly version of Windows does it work on

I see in Device Manager [...] SPI flash chip properly connected - Windows CH341A v1.34 programmer detect and work OK

---

Hi ,
my chip is Winbond 25Q128JVSQ and there is no such type in software, I tried versions 1.18, 1.29, 1.34
Is it a matter and which type to choose or use autodetect?

Moreover, if I read the chip by CH341A programmer and then run check (i.e. in software I press Read button and then Verify button), verification passed only with 1.18 ver. while under 1.29 and 1.34 it says that chip is in disagreement

Please advise, before I proceed with flashing, how to be 100% sure that I have a proper dump and which software to use?

@Hyppo - Try 1.30 and 1.34, use ID W25Q128FV, then do same in ASProgrammer 1.40, compare all three dumps in hex, or send to me.

If you can't get it, the only one I've found that has all the JV variants in it's programmer list is FlyPro, you can get these on ebay I'm pretty sure

@Lost_N_BIOS
It looks like there is a bug in 1.34 version?

I tried following combinations
AsProgrammer_1.4.0 with W25Q128BV profile
AsProgrammer_1.4.0 with W25Q128FV
AsProgrammer_1.4.1 with W25Q128BV
AsProgrammer_1.4.1 with W25Q128FV
CH341A_1.18 with W25Q128BV
CH341A_1.34 with W25Q128BV
CH341A_1.34 with W25Q128FV

And as I see in Winmerge only dumps from 1.34 are different and in addition they don't pass verification. While all other dumps from 1.18 and 1.4.0/1.4.1 are identical.

Does it mean that I'm good to go with 1.18 dump?

Thanks

Could be bug in there, but I've not had issues (with other chips), however it's not compatible with this chip by default so that may cause this.
It also may very well be the opposite, and 1.34 is the only good one! 1.18 is very old software, I wouldn't expect it to even have W25Q128 anything in it, so you surprised me
That package is too much for me to download just to inspect this, remove the BV dumps for now... Hmm, actually, please send me these, in a 7zip archive with max compression set

AsProgrammer_1.4.0 with W25Q128BV
AsProgrammer_1.4.1 with W25Q128FV
CH341A_1.18 with W25Q128BV
CH341A_1.34 with W25Q128BV
CH341A_1.34 with W25Q128FV

Yes but at least 1.18 passes self verification



while 1.34 doesn’t



And I didn't get how verification in AsProgrammer works, when I press button Verify IC it just says that process completed but with which result?



I also repacked dumps as requested @Lost_N_BIOS, 5 dumps are 11.6 mb, it is under this link
https://www.sendspace.com/file/wjt44f


PS And here is datasheet
https://www.winbond.com/resource-files/w...2018%20plus.pdf

@Hyppo - Self verify cannot always be trusted, this program can verify a all FF or 00 dump or write. It may be verifying it's own read error, while 1.34 isn't allowing that, so the bug may be in 1.18.
But, looking at your dumps, yes, 1.34 are both bad dumps, however this does not mean others are OK yet. I need to see stock BIOS for this system, please link me to the exact version 1.06 from the manufacturer (not you upload the file, I want the manufacturer package etc, so I can keep in proper folder)
On ASProgrammer, if there is error it will show error in red, otherwise OK.

@Lost_N_BIOS hi, stock bios you can download using this link
https://www.acer.com/ac/en/US/content/su...roduct/7983?b=1
it is version 1.06 from 2019/08/19

And regarding the dumps, I can confirm that those made under 1.18 and Asprogrammer are correct one. I also found another program for flashing - it is Colibri ver. 1.0.1.62 and it also recognizes only BV or FV chips but dumps made by it are also matched to 1.18

And main thing, yes 1.18 can make the dump and it can successfully erase the chip. But when I tried to program - it immediately thrown an error about timeout and didn't do anything. I tried many times with it but no luck. And it was quite scary minutes))
But then I tried Colibri and yes, it works and flashes ok in about 2 minutes! Then I can open again 1.18 and make verification and it is all passed. There is also verification procedure in Colibri which also passed.

PS I didn't try asprogrammer so can't say whether it can flash ok. But Colibri is fine.

computer: Lenovo D30 Thinkstation
BIOS chip: MX25L12835EMI-10G, 16pin SOP

I have a CH341A programmer. How do I attach either a SOP8 clip or SOP16clip to this? If you look at the schematics, even though there are 16 pins, only 8 pins are actually used, I'm not sure why Lenovo chose this configuration. The problem is the pins with data are separated by NC pins. Do I just wire then individually? I don't think I can use a SOP8 clip? Can I still use the CH341A?

@Hyppo - can you link me to this Colibri software version, or upload a copy for me, all places I find I need to join to download, I could only find 1.0.1.62
If you ever do test ASProgrammer writes, let me know outcome so I can keep in my notes for your BIOS chip ID W25Q128JV

@nikey22 - pin one is where green dot is, connect pin one of SOIC16 clip (red wire usually) to this pin. Yes, you can use CH341A, and this is common about only some pins being used. You can't use SOIC8 clip, it's not wide enough.
Here is common pinout for SOIC16 to use only 8 connections to CH341A - https://www.osresearch.net/SPI_flash + See also - https://nsideattacklogic-tech.blogspot.c...f-embedded.html

Actually, see here in the PDF for your chip - https://media.digikey.com/pdf/Data%20She...MX25L12835E.pdf
Page 7 has the pinout, you connect that to the CH341A pins on side w/ same labels, or you could insert into socket as well like regular BIOS chip / DIP8 if you wanted

@Lost_N_BIOS, thank you!
Should I use ASProgrammer for writes/reads b/c this is a 128 type chip or even the Colibri software that @Hyppo is using? From the previous posts it looks like the base CH3341A software doesn't verify these chips correctly. Thanks.

I have some doubts that Colibri erases chips well but it writes definitely fine.
And a program which can do everything good in my case - i.e. erase, write, verify - is AsProgrammer 1.4.1 so I use it for everything
If you need Colibri @Lost_N_BIOS you can register on their site and download from there (free)

I scanned the attachments on post 1 on VirusTotal.com and got bad feeling after it showed tons of hits (probably false positives).

Anyway I saw ASprogrammer 1.4.1 on GitHub includes working drivers that show up completely clean so I gave it a shot and had success reading/flashing a GD25Q64B chip on a Asus z97 board.

Hi all, now I cannot open AsProgrammer 1.4.0 in my PC (win10). Can someone give me the link to download v1.4.1?
Thanks very much!
