Re: CH341a SPI / I²C programmer
tried with the same result. One of the backup EEProm chips has lost one of the legs. I'm giving up. At the very last attempt I tried even with hot swaping hoping to fool asus flash tool, no sucess but nothing damaged.
BTW how to navigate dlcdnet.asus.com for new bios? Their regular site does not show 2604.

Re: CH341a SPI / I²C programmer
To answer questions:
I have original chip working, dump from it does not work on other chips.
Both flashers broken- possible but that would be a bad luck.
Spork Schivago seems to be right. Original chips with extra data are working that is why there are so many positive results in the net.

Re: CH341a SPI / I²C programmer
Hi
Tried with the dump from original w25q128FV with removed CAP. same thing.
What i've noticed that none of the flashing programs are reading all the areas of the ROM. The part FD44 is missing. I have one dump from original ROM with this data but I'm pretty sure that it is not being written to other chips.
Summary:
I think that the original chip has some info written in area not seen by programming soft.
At the very begining I played with the original chip and bricked it. Reflashing...

Re: CH341a SPI / I²C programmer
Tried flashrom_CH341A for flashing. Verification passed. Same symptoms at boot. Maybe there is a boot section which need special care?

Re: CH341a SPI / I²C programmer
Thanks but it didn't help. Tried to erase the chip and fill it with EE values. Looks like some areas are not reprogrammed. Checked it twice and the areas are not the same- at least few. Looks like problem with CH341A driver/ software....

Re: CH341a SPI / I²C programmer
Hi,
Trying to activate Intel Speed Shift on my Z170p d3 led me to buy CH341A and two W25Q128FV to try.
In all scenarios I removed the CAP header using UBUTool.
Modified 2021 (not sure) bios file with AMICPB 5.02 by changing the access to USER for Intel Speed Shift Option.
Problem:
No matter if I write vanilla bios to [B]new[/B] EEPROM or modified one my mobo starts for 2 sec then switches of for 3 sec in a infinite (max 20 tested) loop. No display no beeps.
Tried CH341A v 1.13 and 1.29 - same...
