After that, I also had a very strange behaviour vs the third party Drives I installed in this machine (reported elsewhere: Yellow triangles with "!" and an unlocked lock, then Locked and unavailable...)

According to your description, the issue happened after installing the latest BIOS update. I suggest that you may try to use Dell BIOS recovery option to roll back the version.

We now have a formatted flash drive and downloaded bios file. Copy the bios file, A3500_A10.exe to the flash drive. Open PowerShell or Cmd (Windows key + R and type CMD ) and go the flash drive. Run the following two commands to create the hdr and rom file:

Buenas, soy de Costa Rica, pude recuperar una laptop Vostro 3500 Dell, gracias a ustedes. Segu las instrucciones, en mi caso solo tena una USB de 8GB y cuando la formatie en refus 3.17 portable lo hice con la funcin de arranque: freeDos Sistema de archivos: FAT32 con el mnimo de bytes permitidos en el Tamao del clster que eran 2048bytes.

Luego descargu de la pgina oficial de Dell el Bios de arranque Dos la ltima versin segn la etiqueta de mi mquina permitida era la A10 selecccionando windows 7 x64. Aunque ya haba intalado Windows 1064 siempre funciona.

copie el archivo descargado 3500_A10.EXE en la USB luego abr el cmd en modo administrador me coloqu en el nmero de letra asignado para la usb en mi caso F: quizs a ustedes la tenga en otra letra pero de igual manera le ponen los dos puntos despus de la letra que les puso el sistema a su pendrive.

Brother, your solution was very effective, for a vostro 3300, change the names to winery30.hdr and winery30.rom. I followed your steps and it allowed me to recover the bios and even install the bios that had problems.

The accepted method is to update the BIOS with the official A12 version BIOS first and then update the BIOS again using the Modded A12 BIOS version.
Any and all info related to this modded BIOS is in the link shown above and it is advised you read through the posts for such information as you require for your setup and obviously prior to any further updating from A10 version BIOS.

Thank you so much! Why is that information not available at the dell.com site and where did you have that information from? At dell.com is only that: -us/sln300716/how-to-recover-the-bios-on-a-dell-computer-or-tablet?lang=en

Gracias, no he logrado entrar al modo recovery en mi vostro 3700 con otros metodos, voy a probar tus instrucciones: con la tecla fin y el dispositivo usb formateado con rufus en freeDOS. Luego les comento, deseenme suerte.

This instruction is for BIOS update 3500A12.exe, otherwise the same method for other BIOS update downloaded file but obviosly the file name has to be changed in down below instructions for writehdrfile and writeromfile extraction from the exe file.

It is thanks to you Rudy, that I managed to recover by following your procedure, after no success multiple times, I searched for the latest Rufus Software and formatted the dFlash drive to 512, and succeeded recovery.

You could try removing the Hard Drive and following the above Rudy procedure, I formatted the Flash Drive with latest Rufus in 512 bytes, worth a try, Flash Drive I used was 1GB.Hope you have Luck, I have no idea in Flashing BIOS while on Motherboard

Yeah, even tried in Windows XP on virtual as i thought it might be issue with win10 and tried on all BIOS exe available on Dell support (A11, A12, A14) /writeromfile /writehdrfile -writeromfile -writehdrfile and nothing ? just starts flashing software

Hola, s que ya tiene rato este post, pero quiero saber si me puedes decir como lograste hacer que botee desde la usb, tengo la usb formateada con rufus, he intentado con 512 y 4096, tengo los archivos como los solicitan, pero al momento de conectar solo encienden el ventilador y no se ve nada en la pantalla, me puedes ayudar? saludos

Thanks for a great instruction. Just recovered my Vostro 3700 which failed during a BIOS A12 update. Carefully followed all steps and it worked first time using the rearmost USB socket on the right hand side. I will now leave well alone on the original A10 BIOS !

Hi Rudy we copied the files and plugged the USB in the laptop in all 4 ports but still no luck it keeps restarting the lights flash and you hear the fan kick in then it all stops and it repeats the process just wondered if you have any other info that would help us

Hi Rudy and everyone,
I have a Dell Vostro 3700 with this problem. I have followed your instruction and your recommendation but it seems not working for me. But what i found out is that, i do not have amifldrv64.sys in my flash contents.

I have tried with both 2Gb, 8Gb and 16Gb Flash, but all to no avail. I also tried different USB ports on the Laptop. After the Laptop tries to read the flash, nothing happens. I also download Dell Vostro 3500 Bios to see if the extraction would have the amifldrv64.sys but it does not have it either.
