Are you in the right place?
You can use pwd to see what directory you're in, and ls to see what's there.


I've been two days with this and I can not, I do not know how to load the bin, I'm new to linux but I came well in the part where it is used *. / flashrom*, that is, if I have an answer from my monitor, if it is correctly identified, please help me

Code: Select all
pwd
is the command to show the present working directory.
Code: Select all
ls
lists the contents of the current directory.
Code: Select all
cd [directory]
is the command to change directory.
Code: Select all
.
is the shortcut for the current directory, so if you try to run ./something then that something should be in the current directory.

Either the program isn't where it's supposed to be, or you're in the wrong place to be running that command. With the information you've given, we can't tell which.

Re: Firmware upgrade using Linux tool, requires no hardware

Did you download the flashrom folder from one of the links I ve given, copy it to your user-folder or whereever to the ubuntu system and run the following commands:

Code: Select all
cd flashrom     <<< or whatever neccessary is, to change inside the flashrom folder
make -j

I can't see this part in your log, which you have posted ...

Ready, you can update my monitor, the problem is that I was using Ubuntu ver. 16 ..... and download version 14 .... and I could read the FLASHROM folder without problems, only that at the end when the verification was made, I throw ERROR IN VERIFICATION, I was scared because I did not turn on the monitor, but if did it and if it appears with the V004 watch, would there be a problem for it?

Re: Firmware upgrade using Linux tool, requires no hardware

Guys, i need some help please.

I have just bricked my xl270z and i think it has something to do with the flash chip name. In my command i used "W25Q16.V" which was the only chip i could find in the command to list chips.

During the process i got a few "spi_nbyte_program failed during command execution at address 0x0" errno 6.

I have two questions.

- How can i unbrick it, even if i end up rolling back to v2?
- Is there still a way to actually flash V5?

Btw, i used an i5 laptop and a vga cable.

Thanks in advance

EDIT: Ok i just tried the exact same procedure using a DVI port and even with some errors verifying the final state it worked! I am on V5. The only issue is that i still get the same "no signal" bug using display port, very weird no?

try reflashing again.
You should not be getting errors and the no signal bug was fixed in firmware v4. If you still have it, something went wrong.

Make sure you don't mix up XL2411Z and XL2411P firmwares.

Trying XL2411Z firmwares on XL2411P can disable the DisplayPort.
