That makes sense.
Thanx

This is a good guide, although can see how it can be very intimidating, are there any records of permanently bricked monitors?

I've read all the posts in this thread. None. Only the cases of successful un-bricking.

You check how long it takes to read FW. It takes 3 minutes? 7? OK, go ahead. It takes 15? Don't try.
With this precaution, the only way (I GUESS!) to brick the monitor requires having bad luck and problems with electricity. Power outage during flashing might ruin the hardware. And it might not. I didn't tested that and I don't plan to

Bricked monitor is still flashable and unbrickable in 99,9%.

So I accidentally bricked my monitor as well...

I was trying to flash my XL2420Z using Debian and having it connected with DVI cable to my Nvidia GTX 770.
However as I was trying to backup my old firmware from the monitor, I got a read/write error and my monitor didn't start anymore.

Now I booted Ubuntu on my Notebook and connected the monitor directly with VGA. It worked without a problem and my monitor is successfully unbricked.
So maybe Debian or my graphics card is a problem I don't know.
Thanks for the guides so I didn't have to spend money.

Hello,

i cant upgrade my Benq XL2720z. I have so often tried to flash my monitor, but it always fails to hit now. I'm beginning to despair. I have my monitor on the last attempt with a VGA cable + DVI adapter it tries to flash. A gtx 570 is installed in my PC.


Here I want to show you my last try to show you ...

Good, writing to the flash chip apparently didn't do anything.
Please check the connections (especially those to write protection pins) between
the programmer and the flash chip. If you think the error is caused by flashrom

Hopefully, someone can help me with my trouble, greetings from Germany.

Just registered to say a big thanks to pipomolo42 for his work, to Bishi for his post: http://forums.blurbusters.com/viewtopic ... t=40#p5953 and to the site admin for his efforts and the strobe utility.

I was able to flash to V2 firmware on my XL2411z (got it from amazon.de) using a vga cable on a second PC using the ubuntu USB boot.

Hey guys,
unfortunately I'm stuck at :

tristan@tristan-E5010:~/flashrom/flashrom$ sudo ./flashrom -p mstarddc_spi:dev=dev/i2c-0:49
sudo: ./flashrom: command not found

I don't know what i could have done wrong???

Ok I got a bit further after 4 hours. Now after the
# dump current firmware
sudo ./flashrom -p mstarddc_spi:dev=/dev/i2c-0:49 -c "MX25L1605A/MX25L1606E" -r backup.bin
command I get:

FAILED.
Info:reset command was not send. Either the noreset_1 option was used,or an error occured.

Here is a more complete list of where I'm stuck. Please help me
