It is a Benq, no rebrand.

Hi i just tried to update my Benq XL2420Z from v1 to v4.

At the last Step i get this

Calibrating delay loop... OK.
Info: Will try to use device /dev/i2c-1 and address 0x49.
Info: Will reset the device at the end.
Error enabling ISP mode: errno 6 & 6.
Please check that device (/dev/i2c-1) and address (0x49) are correct.
Error: programmer initialization failed.

I got no expierence with Linux.

I Just started the whole process again and look its working ! :D
Thanks for the nice and Easy Guide

Hi guys,

I followed the instructions and have a XL2720Z connected with VGA to my Notebook.

Creating the backup worked fine, but I can't write the new firmware:

Code: Select all
ubuntu@ubuntu:~/Desktop/monihack/flashrom$ sudo ./flashrom -p mstarddc_spi:dev=/dev/i2c-1:49 -c "MX25L1605A/MX25L1606E" -w firmware.bin
flashrom v0.9.7-r1846 on Linux 4.13.0-16-generic (x86_64)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Info: Will try to use device /dev/i2c-1 and address 0x49.
Info: WILL reset the device at the end.
Found Macronix flash chip "MX25L1605A/MX25L1606E" (2048 kB, SPI) on mstarddc_spi.
Reading old flash chip contents... done.
Erasing and writing flash chip... Error sending write command: errno 6.
spi_nbyte_program failed during command execution at address 0x0
Reading current flash chip contents...
done. Looking for another erase function.
Error sending write command: errno 6.

No usable erase functions left.
FAILED!
Uh oh. Erase/write failed. Checking if anything has changed.
Reading current flash chip contents... done.
Apparently at least some data has changed.
Your flash chip is in an unknown state.
Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom@flashrom.org, thanks!
Info: Reset command was not sent. Either the noreset=1 option was used, or an error occured.


I tried it several times with unplugging the screen for 15s in between.

Any ideas?
