Error 43 in the CH341A programmer

The other day I ordered a batch of CH341A programmers in China, which are used to flash 24-25 series memory chips.
But as it turned out, when connected to Windows 10 and 7, a message is displayed that "USB device is not recognized."
Initially I thought that the problem was in the CH341A chip itself, but it turned out that everything was much simpler.

Also, in “Device Manager,” Windows defined it as “Unknown USB Device (device handle request failed)”,
and in the properties, writes about the error "The Windows system stopped this device, because it reported the occurrence of problems.
(Code 43) and, of course, the VID and PID (VID_0000 & PID_0002) are incorrectly defined.
Attached Image

Opening the CH341A documentation and looking at examples of schematic diagrams, you can see that 12 MHz quartz is used everywhere.
Attached Image

And on the CH341A programmer itself, the quartz is set to 27.120 MHz
Attached Image

We take a soldering iron and unsolder the wrong quartz 27.120 MHz and solder a new one at 12 MHz.

We connect the programmer CH341A to the computer and see that the OS has a new device with VID and PID wine (VID_1A86 & PID_5512)

Completion of the programmer
In the process of working with the programmer revealed some shortcomings,
one of them: it is not possible to reset / set the QE bit in the second status register.
We read datashit, for example, on the chip W25Q64FV, and we find the puntQuad Enable (QE) ,
in which there is a warning:
WARNING: If the / WP or / HOLD pins are tied directly to the power supply or ground during
standard SPI or Dual SPI operation, the bit should never be set to a 1.

To fix this flaw, you need to detach the legs #WP (pin 3) and #HOLD (pin7) from VCC
and connect them to VCC via resistors 4.7 com.
On the "black programmer" it looks like this:

In theory, I can, without a clothespin, get to the chip on the board through the JSPI connector

Yes, no, on the panel I have already unsoldered the pins. This connector just sits on them. I now solder the ends to the clothespin.

Well, or advise other flash drives from 512mbit and higher (preferably not wson8, but so-8 (sop-8, soic-8 and similar)

In my adventures things are like this:
Half a day soldered clothespin, somehow managed to win it. The fact is that the contact disappears in the most unexpected places. Therefore, wherever possible, you need to apply soldering. I certainly understand that anyway the contact may disappear on the chip itself and even during the firmware, but I will try. In extreme cases, if it does not work out, I'll try it in a way through the JSPI connector.
In general, I collected a clothespin, put in a chip, which I thought he was dead, and about a miracle, he decided. Erases and writes. But not all programs from the caps work correctly for me. On some, when you click on the buttons, you get out some windows and these programs have to be killed through the DZ.
If there are tips on the firmware on the mother, then I will listen to them all with pleasure. So I am an ordinary amateur, but this is a useful experience for me, and it is even interesting. I think that I will even continue experiments with this device.

Sewing with a clothespin on the board is a Kashchunism) when I just started, I also indulged in it, but on the board it never went out normally to flash, I always unsoldered. Write how you will pass)

* goldknight ,
I flashed it, but there are no coincidences. It is on the board which. And which is not on the board of norms coincides completely. I do not know what to do. Re-solder? I have a soldering iron of 60 watts, and I never soldered chips ...
P.S. Errors showed when sewn compared in a hummingbird. Now I have prog 1.29 in auto mode and it seems to be normal. So should write?

The programmer heated up at the port while he sewed. Is this normal or not? Maybe because he sewed a cheoz hub? From the hub to the company two meters cable. Additional power to the hub is not served.

* teodorr, I hope you saved what you had on the chip before the firmware. With firmware on the board, you need to remove the battery. You can remove an ordinary soldering iron from the board if your hands are not crooked and there is an alloy of a rose.

Rep: (8)
* goblin-gramotey, what was sewn there in what format? if bin or rum then normal, if f2, 70.80, cap. it will not work very well. Before the firmware, the data of what was on the hdd computer is saved before. in bin format. Then the button is pressed, then if the erasure lasted at least 20 seconds, the new image is sewn in the bin or rum format and not in the uefi capsule format.
