Need some assistance with BIOS flashing with ch341a

[Ferd]

My mission of learning to desolder and resolder would be a complete success at this point.

Again Just make sure you practice on something else , find a dead motherboard of some sort and play with that first, use the biggest tip possible for your soldering iron, avoid heating up the board or the chip for too long, and no matter what happens don’t pull or push anything by force , the solder should melt and become like butter and that’s how you avoid collateral damage to the pcb

No just a small paint brush preferably natural hair as synthetics will burn anyone selling specialist brushes for soldering unless silicone is another scam and don't fall for it

I think you're just angry. No room for that in this discussion. You're looking for trouble and I'm not interested.


I got some paste flux, do you recommend liquid flux, and if so, which one? I saw some tutorials and I didn't see them use paste, only liquid. Thanks!

There is no anger in what I wrote. I'm not looking for trouble.

You came here asking for help, and I gave a solution.

Sense says to chuck the card for frying 5 programmers. Insanity says to continue trying to fix a card that is obviously toast and continue wasting more money by continuing to fry programmers.
(Doing the same thing over and over to expect a different result is the definition of insanity)

So you can continue on the path of ignorance, Your choice.

I did warn you.

Both do the same thing, different products have different quality, there are top tier flux in form of paste , and also liquid one ...
Again this is only going to slow you down , start with whatever you have /you can get I can go all day about which flux is better and why but it won’t help you as much ...
If you can get a genuine Amtech flux that would be great , if not than it okay

CH314A programmer regulator will overheat if you connect the clip the wrong way round. It's sounds to me that what you have done or you have crossed threaded the clip

Ensure you are connecting pin1 all the war back to the programmer pin 1. Watch a few YOUTUBE videos as it seems your need a refresher how to use it.

I thought so too , but then he got it to work with other chips
Either way a refresher is needed indeed

Then OP may also have a broken wire(s) on the back of the clip. Tap it out with a meter & solder it back (if broken). They do break but you can't see it as it's covered by insulating rubber or some-kind of heat shrink wrap.

I connected it properly, 1 to 1, thanks for that info!

The CH341A I had has a jumper pin on it to select voltage, and it defaults to 3.3v. I would think if it was set wrong, you would damage the BIOS chip, not the programmer. I've even clipped the thing on backwards by accident before with no permenant ill effects. Do you have a picture of the programmer you have?

Yeah I have, I'll send it out...

Ok, here's the picture. Let me know what you think! Thanks...

Have you heard those black PCB flashers have a 5v flaw. They are designed to give 3.3v to BIOS chip but can supply 5v if not modified. - https://www.win-raid.com/t796f16-Gu...rogrammer-to-flash-SPI-EEPROM-5.html#msg43126

Could this be your cause of trouble?

EDIT - I guess not, if its frying the programmer. Still, I share and understand your thirst for knowledge. I hate being told to cut my losses and find other projects when I am invested mentally or financially; but that's good advice in this case! Keep on your quest for knowledge friend!

I got all my soldering kit. I'm working up the time to desolder the chip and try the programmer on it. Also my 10 piece BIOS chips should be in the mail soon I can only hope, it's coming from.... China...

That's the same one I have. It's set to put 3.3v out in the default jumper pin position, which yours is in. No clue how a card would be frying it. Probably a dumb question, but you're not plugging it up to a powered card, are you?
