Goyo Posted September 21, 2022 Share Posted September 21, 2022 Hello, new member hoping to get some help, thanks for reading. I am trying to flash a newer BIOS on my P751TM1-G to solve an issue with the display via Thunderbolt, but I have been unable to flash the files I have found with the instructions I have found after two days of research. I have been reading around before writing this post but at this point I feel like I have to ask directly. I have had to research to flash firmware on an older laptop and on my phone a couple of times in the past, I have done hardware repairs and modifications; this time I've been trying and I think the better course of action is to ask. I have downloaded the BIOS 1.07.29 for P7xxTM1-G from https://my.hidrive.com/share/yze8mg-wf8#$/BIOS and EC Firmware/CLEVO/P_Series/P7xx_Series/P7xxTMx/P7xxTM1(G) found at https://clevo-computer.com/en/drivers/ I have tried to follow the instructions from the Obsidian PC video https://www.youtube.com/watch?v=IQIkkr2Zaro but the files they copy into the USB pen are not the same as the ones I get from the link above. I actually got this machine from Obsidian but they seem to have left the Clevo reseller business. When I disable UEFI boot and boot into the USB, "dir" to see the folder contents and try to run the file that looks like "meset" (since my files have no step1.bat) the result is "This program cannot be run in DOS mode."; it doesn't respond to "flash" or similar commands either, but I don't really know what I should be doing here. I have found this other file for this model but it is in the form of a .ROM file and I don't know how to use it https://www.mediafire.com/file/fxnau0mq310462p/P7xxTM1_B0724.rom/file I have also found another download link for .ROM files for a dsanke BIOS but again I don't know how to use them. Apologies for not linking everything, I have 70 tabs open now, I'm also trying to keep the question clear. All this explained, I feel it is more prudent to ask for help here where someone who knows the process could point me in the right direction, how I can flash the 1.07.29 BIOS that I have, or which other BIOS I should use and how to use it. Any help would be much appreciated. The reason I want to update the BIOS in my P751 is that my current one (1.05.10) appears to be lacking a setting to allow display over Thunderbolt (I cannot find DDI Control in my BIOS, which seems to be what I need to change, I have installed TB drivers and researched this process before deciding to update the BIOS because the DDI setting is nowhere in mine). This laptop has TB3 and I get USB and Ethernet signal through it but no Displayport signal (if I change Thunderbolt security in the BIOS from "Unique ID" to "Only DP++", I get no DP and no USB; no TB connection recognized). I am using a WD22TB4 dock which works correctly with my newer laptop, a Clevo L141PU, so the problem is with my P751. I have been using two external monitors connected through DP cables directly to the P751, but I want to use all the setup with the L141 too (all works fine now in the ultrabook with the one TB cable) and ideally plug only two cables TB+power into the P751 instead of the current five cables every time I move it (my problem now: on the P751, TB is recognized but only gives me USB and Ethernet, no display). Thanks so much for taking the time to read. Clevo P751 8700K 1070, Clevo L141PU 1255U. Typing on Plancks, running in Merrell gloves. Link to comment Share on other sites More sharing options...
