I'm trying to flash the BIOS chip of an HP Elitebook 840 G1 and i'm getting the following message (i'm issuing the command - sudo flashrom --programmer ch341a_spi -r new.bin - using another laptop to which i connected a ch341 programmer and a BIOS SOP8 SOIC8 ) :
flashrom v1.1 on Linux 4.19.0-5-amd64 (x86_64) flashrom is free software, get the source code at https://flashrom.org
Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns). Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ch341a_spi. === This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE The test status of this chip may have been updated in the latest development version of flashrom.

i read what it says here ( https://www.flashrom.org/Supported_hardware ) : " ...In general, flashing mobile devices is more difficult ... "
but it would be really really nice if you guys could add HP Elitebook 840 G1 to the list of supported laptops .
Thanks , Nuno Torres
