Oh sorry, I missed that the incorrect file has one more digit in its size than it was expecting (e.g. 2MB instead of 256KB). So I see now, you've got the wrong flash chip configured. You have it set for a flash chip that's only 256K, while the firmware file you're using is 2MB (8 times the size). That 256K chip is probably some configuration storage or maybe HDCP-related chip it found in the monitor, unrelated to what you want to do.

Thanks alot my friend! You've saved me
Apparently I've selected the wrong BUS. Now everything worked perfectly and I'm on V2.
Thank you for your help.

Id'like to thank you very much.
It worked perfectly for me.
I was using my desktop gaming PC.
I disconected my Ati GPU (R9 290X)
I pluged the XL2420Z on the intel's cor i5 VGA ouput and a second screen ont the intel's DVI output.
I installed the last available version of ubuntu.
For those who are not familiar with linux don't forget to install theses packages :
sudo apt-get install svn
sudo apt-get install i2c-tools subversion libpci-dev
Video output for the 2420Z was disabled (display menu in ubuntu) and screen was in standby mode.
I followed the blog's instruction : don't forget to download and use the proper firmware at this step : dd if=
XL2420Z_V2_20131209_4D1F.BIN of=firmware.bin conv=notrunc . The firmware shall be in the /flashrom directory)
And that's it.
Again thank you very much

Oh lord, after reading every single comment on this post I really want to try updating my firmware, to bad I'm not man enough to take a chance on bricking my 500$ monitor. Guess I'll just keep my monitor on V1 and hope that I'll meet a person familiar with linux in the near future or man a bit up.

You won't brick it. go to page 3 or 5 and follow the instructions for the umbuntu flash boot disk.

I'll probably go for it after I call the place I bought it from to check if they can do it by any chance, a slim chance, but still a chance worth taking as I think if I do it myself I could have some warranty issues.

Hello, and thanks for the instructions. I've currently connected my XL2411Z this way:
Graphics card DVI output -> DVI to VGA adapter -> VGA cable -> XL2411Z VGA input
Following the steps here, I've been able to successfully complete all of them up to the last one, where the firmware writing occurs. Before proceeding, I thought I'd ask you to be sure if it's okay to do this, as I'm not using the recommended (?) pure VGA connections.
