  • I unzipped the file you sent using winrar and opened command prompt as admin. Ran the H2OFFT file and it did not work. screenshot attached is what I got.

    Believe me, this is already hard enough, I am by no means trying to overcomplicate anything. Would really love a simple solution.

    I tried to run my own modified 1.12.0 where I changed the version number to 1.13.1 using cmd prompt in admin and it did not work, just auto restarted again....

  • I highlighted the changes I made to the flags in the isflash.bin. Did I make the changes in the right place?

    I'm not sure for "Bios_Version_Check" if the flag is where it says "Flag=" or below that at where it says "default". On the other one, Project ID, I could not find a "Flag=", only a "default". Unless I was supposed to change the "Flag=" immediately after "Platform_Check" to 0? I set that to zero too just in case.

    Also, under "ForceIHISIVersion" I wrote version 1.12.0. I am trying to...

  • Ok so it did not brick it, but I had to "CRTL-ALT-DEL" to get it to boot windows again. It just restarts the laptop as soon as you tell it to flash the bios. So I can confirm that method does not work.

  • I made an SFX executable. It just created a new folder with the original .exe in it. When I unzip the .exe, I do not see a platform.ini file.

    However, searching for "platform" in the hexdump shows like 50 instances. I found two flags by searching for "version check" and "platform" that I flipped from 1s/2s to 0s to not perform checks. I read in the hexdump it does a version check by BIOS version as well as by application.

    This did not help though I still get the same error message when trying to flash the bios to a lower version. Could you...

  • Both of those files you uploaded are identical to the bios files created by using the extractor tool. Hope you did not pay much for them....

  • Tried to reflash bios back to 1.0.1 using a bios image I made with the extractor tool. What I write to the bios chip and what is actually written to the bios chip are two different files. The file called "read_file_11" is what I read after I flash the "BIOS-UEFI" file. Tried to boot the laptop on 1.0.1 and got the same problem. Rainbow keyboard wave, max fans, black screen, 2 red 2 blue flashes indicating bios problem.

    I tried flashing a bios image of the version my bios is currently on (1.13.1) from Dell's site, and it did not work, still does not boot.

  • I tried to re-read my bios to make a backup before writing, and everything came out to all zeros. I may have worn down the pins on my bios chip too much to rewrite it... I cannot test out that new bios version. [USER="354913"]JJong[/USER] for the M18 specifically you have an EC chip that is flashed alongside the bios. However, the M18 only has one version for the firmware called "Axiom_Infinity_FW13_1zone_FW_0_2_4_webpost_20231205.exe". I think this is beyond me. I figured all I'd have to do was hook up a chip and be done in 5 minutes.

    Edit: wait the clip unplugged...

  • I've tried to run BiosUtilities by platomav before. Someone else posted it on this forum a while ago. It just says "Done!" then closes without actually creating a bios image or giving an error. I managed to get it to work w/ your instructions.

    The bios I extracted from Dell's .exe for 1.13.1 using a hex editor is the same as the one that is created using BiosUtilities, however, the bios for 1.2.2 is not. The bits are shifted 5 to the left in the one made by BiosUtilities vs the one I extracted and flashed with a hex editor. Meaning I missed the first 5 bits and last 5 bits...

  • The raw .rcv file is is 33.96MBytes, too big for the chip to hold. The file you flash needs to be 32MBytes exactly. I don't think the version I tried to flash was the issue. It could be an issue with the EC chip, but I don't think that is the case since I could not find an EC image in the bios file. I think the M16 might not have an EC chip.

    I think the problem is something to do with one of the other images to flash. A "CTRL-F" for "IFLASH" through the the bios file reveals that there are more images than the bios image.

    There is a 'DRV' drive image,...

  • I got impatient and tried to flash bios back down to 1.2.2. I ended up bricking the machine. I restored the previous bios file I had backed up earlier and that un-bricked it. Whatever I did to make the bios image file was not correct. That or I went back too many versions at a time, though I don't think that would be a problem.

  • piernov[USER="169897"]piernov[/USER] Is there anything I need to know for flashing the bios? I've made 4 backups of the bios file. A few bytes (108,847) changed from the 1st backup vs the last 3 which are all the same....

  • Some good news and some bad news.

    First of all good news: I can confirm that is in fact the bios chip! I was able to read it using the adapter I bought. >98.8% match of all bytes.

    Downloaded AsProgrammer from GitHub and installed the driver that was included before starting the .exe (don't forget that). Took off back panel, unplugged battery, selected the matching chip in AsProgrammer (MX25U25673G) and used the probe to read it. I used ImHex to see any differences in the bios files that I read vs the bios image from HxD I pulled. I also used a Python script to find...

  • Alright, picked it up. Will take a week to get here, and I'll try to read that bios chip when I get the probe.

  • Would a WSON8 Chip probe like this work for flashing the bios? Here is the link: [url]https://www.amazon.com/WSON8-Probe-Write-Burning-6X8mm/dp/B0BJ2682MG/ref=sr_1_5?dib=eyJ2IjoiMSJ9.SZbMJaGdSUBGuqdezPn8VnaUOuvxMsl2JlQgzLdUWYodY-kB6q_SC7gU7UgAK6NX_TM10DaRgn2pGqqTwthWmkax2-k9g5k3mMvjZtvnyWyNAV1j-N2yoCgR9haybhHr5ACWg4LAPQYZW9UwUfvsRwiF1VVm55Lpnw-mvGl86funhHzUT7Suf6KyAtWPAHxtx05Ol5mUtfX9azD7V5xSHbh5kO2i-oUdAwtYULDK-PDgYTW9s3jhluGxrJoPVKkoA_v95vaEj3nxKInEtk_byMaMePTvVA3bQu5wYEkgSmw.cR72YDux7xZi_06selMhZBOQ1FuAawJxelzpXifkPbs&dib_tag=se&keywords=wson8+6x8+probe&qid=1717264962&s=ind...

  • I will get my CH341a programmer in a few days and will see if I can come up with some creative way to connect to that chip that does not require temporary soldering of a wire to each of the pins. I'm fairly certain that's the bios now, seems like something Dell would do to make flashing it tedious....

  • Were you able to put a CH341a and do a dump on the chip in the red here? (It's on the side of the motherboard with the ram, so just need to take the back panel off.) I went on win-raid (bios modding forum) to ask where the bios chip was, someone suggested that is the bios chip. I don't have my ch341a programmer yet so I cannot check, but [USER="169897"]piernov[/USER] thinks that was the chip as well. The chip has "256" written on it, that may be its storage size, 256MBit = 32MByte. Test that one if you can manage to get the ch341a clip on somehow since it is kind of wide and...
