Firmware upgrade using Linux tool, requires no hardware

Discuss BENQ Blur Reduction (strobe backlight) and the Blur Busters Strobe Utility. For Z-Series monitors (V2 firmware) on XL2411Z, XL2420Z and XL2720Z.

Hi,
That looks like a winbond flash chip. I believe when I flashed my Asus VG248QE with the Mstar ISP device, the Mstar ISP also identified the Asus with that same flash chip. That's really strange.

I wonder what the RT809F and Mstar ISP device (I own them both) would identify your XL2720Z as. They both identify mine as MX25L1606E.

I just successfully upgraded firmware to V4 for my secondary XL2411Z, using my main desktop with GTX970, DVI-DL cables (no laptop, VGA available, and couldn't be bothered with SSH).
Primary monitor (again a XL2411Z) did not show in i2c functions. I'll probably switch the cables around and re-run to do the other one.

The reason I'm posting is simply to advise that I had to update one of the steps as I was unable to connect to svn://flashrom.org, so if you're reading this and having issues with step it might help you too.

Code: Select all
#svn co svn://flashrom.org/flashrom/trunk@1846 flashrom
# updated to ->
svn co https://code.coreboot.org/svn/flashrom/trunk@1846 flashrom

It would be lovely if it's possible to create an ISO image (thumbdrive compatible) that automatically boots up Linux & launches into a menu to automatically flash the monitor with minimum steps. Automatically boot, automatically detect, and then display a menu (confirm before flashing).

-- Easy to read select-an-option full screen menu with no technobabble.
-- Including backing up, and selecting between multiple ROMs (V2, V3, V4) to flash new firmware.
-- The ISO should contain ALL BENQ firmwares in existence *and* ability to add new firmwares (query a folder/directory full of firmwares).
-- Can upgrade any firmware-upgradeable BENQ monitor with appropriate firmware upgrade
-- Safeguards against bricking a monitor (will refuse to firmware-upgrade wrong monitor)
-- Including a HELP screen (e.g. help.txt)
.......e.g. display tips such as cable swaps, using correct cable, etc.
-- Including a diagnostics menu
.......e.g. recommending cable swaps, retest, reprobe, display output of monitor probes
.......In the background, every output should be logged to a file. Diagnostics menu should be able to display contents of log (using a page by page viewer such as 'more' or 'less')
- All the above should be easy to later customize by a programmer for future firmwares & possibly other Linux-upgradeable monitors.
- Add a neat Blur Busters cameo of some kind (ASCII UFO, etc).

A good bash script programmer should be able to do it :)
Then users can just can burn the ISO, and then boot into it to (mostly) automatically flash a BENQ monitor.

The menu should be usable to non-Linux users, of a lesser computer experience, so that it's mostly burn-an-ISO operation.

REWARD: USD $75 Amazon gift certificate from Chief Blur Buster, for an ISO to the first person that posts a link to a safe, trusted, verified ISO that does all the above /safely/ and /automatically/ with just one keypress (without bricking a monitor from a wrong keypress). Please also post a secure hash for the file (e.g. SHA-2) for safety purposes.

I have the zowie XL2411 with V006 firmware, i could try to upload it here if someone is interested. (Need instructions to dump it though, got a debian VM running)

Try this from here:

viewtopic.php?f=13&t=779&start=200

These instructions should still work with Ubuntu.

BTW if anyone has XL2720 V6 or newer (if it exists; Zowie rebrand) please post.

The i2cdetect asks me to scan bus 0, but then doesn't find anything. This is with debian jessie...i'll download ubuntu 14.04 and see what happens (doing this because i read that proprietary amd drivers do not expose i2c bus)

If using Ubuntu and my instructions, it will work perfectly. You may have to check from buses 1-6, depending on how many ports your video card has.
