How to flash BIOS via EZP2010 + SPI pin?
Hello, I have a laptop (Lenovo G510), you need to flash a microcircuit (to remove the white list of hardware) BIOS without soldering (hands are crooked for soldering). For these purposes, an EZP2010 programmer + a clothespin for SOIC8 was purchased.
Actually the problem: I cling to the microcircuit with a clothespin, turn on the programmer to the USB port, Power is on and Run flashes, I launch the program (which is complete) and press Detect, in response I get a chip detection error (the chip is alive and working) and Run stops flashing (it goes out). Microchip Winbond 25Q64FVSIQ I
thought something with a clothespin - each contact correctly rings with the other end.
Accordingly, both reading and writing do not work. I connect correctly (the first leg to the first leg, according to the numbering)
Please help.

Better late than never - the problem turned out to be in the EZP2010 itself, or it gave the wrong voltage or got caught, in general, I took CH341 and immediately flashed
I advise you to straighten your arms, solder the microcircuit and program it alone on the programmer. The use of the Rose alloy greatly facilitates soldering.
To explain what is happening briefly, when you try to program a flash-memory chip with a clothespin, at the same time the programmer tries to power a number of other microcircuits that are powered by the same power bus, for example, a multicontroller, some hub blocks, or someone else. The programmer is not only not designed for this, but often carries protection against increased consumption of a programmable microcircuit. Plus, all those microcircuits that we inadvertently powered up begin to live their own lives and the multicontroller that turns on can begin to read its firmware from the flash drive, and the programmer tries to program it.
Is there a list of 25 series chips in the programmer software?
Here they write that if they are not there, then you can’t decide automatically.
