Update Studio 1747 to Revision A10 with 1747A10_W32-64.exe After running in the troubles described above I fortunately found this post. So I first could successfully recover the BIOS rev. A7. (The extraction of the BIOS1.WPH file did not work for me on DOS with the revisions A08 and A10). After having a running system again I opened a command shell and started the 1747A10_W32-64.exe. The installer starts without asking the flash process; please note where the extracted files are placed (C:\Users\Administrator\Local\Temp\WinPhlash64 or something like this). After extraction of the files and before touching the BIOS the installer stops with an error message. I simply took the BIOS1.WPH file and did the work described above with this file. Now I have a running system with the newest BIOS version. I hope this helps everybody that will probably fall into the same trap.
Thread revival....So the 1747 blue screened during a BIOS update and when I start it up its just a blank screen with 3 beeps. I found the latest BIOS A14 from dell, extracted the BIOS1.WPH, renamed it, ran the wincris.exe and created the USB. When I plug in the USB, hold END and turn the computer on the USB drives flashed for a minute, then nothing happens. Is this thing truly bricked?
Have you contacted Dell at all for technical support? That should always be number one on your troubleshooting list before coming to the forums (even tho this whole website could kick any OEMs but lol)
From the avtivity you describe I suspect it is not "truly dead".... something is wrong with your procedure. I suggest trying different type things such as releasing the "end" key faster or waiting slightly longer, trying different usb ports, how is your usb drive formatted? The previous post suggests his included some form of mini dos, does yours? (I think wincrisis.exe installs it, doesn't it?) Maybe try a different version of the mini dos, it should be very plain, no extended memory if mine serves me correctly... no himem.sys file (I think that is what it is called), no fancy drivers...
My 1747 got bricked from a failed BIOS updating. When I try starting it up normally, the screen stays black and I just get a repeating 3-beep error (1 long beep immediately followed by 2 short beeps). I've tried flashing the BIOS with a USB drive dozens of times, and I've tried doing EXACTLY what you've said to do here several of those times. It's still not working and I don't know what else to do. The only thing I can think of that might possibly be preventing your instructions from working is that there's a Dell Recovery CD in the disc drive. When I try flashing the BIOS, I see the LED on the USB drive blink for a few seconds, as if it's being read, but I can also hear the disc drive spinning. I can't get the disc out, the eject buttons on the keyboard don't respond, and there's no pinhole for manual ejection. Could this be preventing the BIOS recovery? Is there something else I can try? Or am I really going to need to physically replace the BIOS chip?
