Re: Dell Precision 7510 7710

I run a ubuntu system on the laptop, so I used a usb stick to update the bios.
Everthing rans without any errors. All flash processes were done, then the automatic reboot and from there on I have this issue.

This was one of my first actions before I decided to use the flashrom method.

So, the first time you updated the bios it was from USB or through windows,did you use the USB only for the recovery ? What did you see on the screen during the update ,did it stop with an error message at some point

Try a bios recovery, download the bios update then rename the exe to BIOS_IMG.rcv ,copy it to a flash drive and put it into one of the USB ports.Take the main battery out and charger,press and hold CTRL + ESC ,plug the charger in and see what happens.

I soldered enamelled wire on the flashrom pins, the end are leaded out of the laptop to a connector that I can connect to a raspberry pi for the programming via flashrom. The verify process is always valid, and the laptop is complete assembled with all its parts.

Hi, SMDFlea I flashed your file, but always the same behavior of the computer. Every 17s a reboot.
Do you have another idea?

Did you use a clip or desolder the chip.Maybe you damaged something or a part such as a resistor has gone AWOL

No, it is not working. Always the same every 17 seconds a reset.

Bios version 1.3.12

Ok,wait for someone to post another bios.As your original version was quite old it might be better if someone posts one with an older bios region,as the EC would be old too.

When I flash peste's rom file, and power on the laptop, starts the updating ME process automatically or is a special key combination needed?

No special key presses needed,just press the power button once and leave it for a few minutes. If it isn`t working let us know.

Re: Dell Precision 7510 7710

Hi peste thanks for your file,
I flashed it, but it changed nothing. Still black screen, no beep, no fan. Only the hard disk starts and after 15s the power button led goes off and on, the harddisk turns off and on and the laptop is trying to start again.
With a pressed D Key before the powering up, I can see the color LCD Test. But this works also with a cleared Bios Flash Rom.

Is it possible that the BIOS update damaged my hardware?

When the ME firmware has been cleaned you need to leave the laptop alone for a few minutes,it will reboot itself.
