What kind of device is using this currently? Seems to be challenge/response SPI flash and would prevent copying and unauthorised updating. No data sheets so difficult to know.Comment

I also found this: https://forum.reveltronics.com/viewtopic.php?t=972
All W74xx can be programmed as standard 25 series SPI FLASH devices. It has even the same chip IDs as W25xx. The difference is in authentication layer. W74M stores up to 4x SHA-256 keys for authentication procedure. What's important - keys are not used for encryption. Keys are one-time programmable - once programmed, it can not be changed. It's usually used for anti-clonning protection.Comment

I apologize if my post is in wrong forum. Okay, i have this problem with winbond w25q16dw ic. It is 1.8v from nvidia rtx a2000 gpu card. It is crazy tiny chip. The problem is that i can not erase it. It only erases something like 2%. I have tried with ch341a and svod3. I do not even know where i could buy this kind of chip. Any ideas how to get it erased? -
Hello folks,
(First post of mine, after introduction).
I came here to seek help for a board SPI reprogramming.
The referred board belongs to an Archer C9 V.4 EU router, which I believe, is bricked, (I was the one to brick it during a flashing operation with custom dd-wrt firmware upgrade).
The IC that I want to flash is this one:
Datasheet for the IC in question .
The one in the motherboard has 16 pins. (There are other IC in the motherboard, with 8 pins each, but I am almost positive that the one that will... -
Dear friends, I want to share my experience repairing an ASUS TUF FX506L gaming laptop motherboard: DABKXDMB8E0_F_BKXD. Boardview and schematic are available, as well as the BIOS and ITE ROM.
When the customer brought in this laptop, it was initially dead; it showed no signs of booting for any reason. After hours of measurements, checking each stage, MOSFET, and seeing if there was a short circuit in any capacitor, I discovered a strange 0.7V leakage voltage on the 3V_S5 rail, particularly on the PL9 coil, with the board not powered on. There were 3V_LDO and 5V_LDO voltages, which... -
Hi everyone,
I hope someone can help me.
I have an Asus ROG Strix Scar 18 (G814JZ) laptop with a Winbond 25Q16JWNIG chip on the motherboard.
Unfortunately, I flashed the wrong file (BIOS/EC/other region – I'm honestly not sure anymore), and now the laptop is completely dead: no display, no fan spin, no reaction at all.
I have a CH341A programmer and I'm able to read and write to the chip. However, I'm not sure which software is best (AsProgrammer, NeoProgrammer, etc.) or if there's anything specific I should watch out for.
A valid BIOS/EC backup... -
Hello, first of all, excuse me, I am using the translator, English is not my native language.
I have a Lenovo ideapad 330S - 14IKB laptop.
The tablet did not recognize me when I connected it, so I checked the device manager and I realized that there were many with the exclamation mark, so one by one I began to update their drivers until the sign disappeared of admiration, I even updated the BIOS, and the laptop rebooted normally and worked, so far so good, but the tablet still did not recognize me, I read on the internet that it could be due to a...
