I bought this a few years back, this little programmer made us so much money we literally ran our shop for months on the money we got programming chips with it, its my absolute favorite.... Merry Christmas from Zimbabwe 🇿🇼🇿🇼🇿🇼🇿🇼🇿🇼
From where u get the software for the chip
@@abdallahharfoush9449 techpowerup i suppose
how is this profitable
@Ruben Chris Some people will attempt to update the bios on their motherboard and it will fail making the board unusable and most people will say it can't be fixed / it's bricked. If you use one of these programmers you can clear and refresh the bios and bring the motherboard back to life.
Example: I bought a Z490 motherboard for $20 because it had a bad bios. I flashed the bios with my programmer and the board works fine now. I resold it for $100.
Bios also gets corrupted by it's own many times
I am 62 and lack the funds to purchase a Microscope as I am weak sighted, but enjoy your videos so much as it just proves that the world needs common sense.
Example: My wife programmed process controllers without Grade 12 maths and science. I did computer science, but branched into commercial systems. She used Fortran and I Cobol. We now look back after more than 40 years and laugh at ourselves. I was thinking in paragraphs and she was thinking in arrays. I later bit the bullet and went to college to learn C and logic mainly to understand my wife.😇😁
Badass couple
Sorin, that is very well explained how programming, and that you need Ampere, to burn something and not volt, and one should not change anything about the CH341A programmer, people always tend to complain without knowing anything thank you Sorin Merry Christmas to you and your family too, from Belgium
I never had problems using this programmer as it comes without modifiying anythink in it. Thanks for the video.
I need the program for this device please, I want to use the peripheral
So happy and grateful you managet to get the channel and videos back.
Finally !!!! Waited for you to step out and say this to all their faces!!!!!!!! Learn electronics and love electronics allways
Have a great Christmas Sorin and thanks again for the all the great videos you put out.
i really needed to understand this programmer before using it since i never used one and i found no videos about how to use it rather than showing it i mean i need to know all about it before using it and someone really did this and im just gonna subscribe
Glad to see you are back up and running Sorin. I was starting to get worried. A lot of people were missing you.
You are absolutely right, Sorin. A couple of years ago I bought one complete SVOD3, but this one was my very first programmer (BIOS chips only, of course). I had never modified it in any way, and it does work perfectly. The worst thig is the chip clip; it is really bad. You are luck, man! It does work for you in the video!.
I agree, the clips are terrible... I've had 2 sets from AliExpress and one clip worked almost flawlessly on half a dozen PC motherboard BIOS chips and the second set of clips was virtually useless I threw it away as it simply couldn't stay on any chip. If you need to program a BIOS chip urgently then it might be a good idea to order at least 2 clips and hope that one of then is good.
Great to see this channel back up!
Sorin.... you are big!
Thank you for the lots of videos with good sense and a lot of experience...
Greetings from Portugal 🇵🇹
"Hello! We are back"... Really!!! 🍾🍾🍾 Welcome back Sorin!! Happy to see you again!
Another great video Sorin! God bless you and your Family!
good to see this channel is back, you've been scaring me for the last 3 days :D
Thanks Sorin for making that clear. seasons greetings to you and your family.
Great to have you back Sorin!
Merry Christmas my friend, big hug, love your videos.
I also brought one of those. In the old times everything was harder. Now so cheap.
thanks for posting all this year and merry Christmas Soring to you and Diane :)
Happy Christmas Sorin and Diana. Thank you for sharing your skills and experience. One hand washes the other, so one day, i will be able to repay you. Have a brilliant xmas with plenty of laughs, warmth and satisfaction that 100's of thousands of people are happier thanks to your videos. Cheers 🍻 🍷!
Very good video thanks Sorin Have a happy Christmas to you and your family
Ya..🙌 channel is back.. so glad to see you again Sorin 😃👏..
Very informative! A non-low knowlege about ch341a programmer original voltage functions and behavior. Ty sir for sharing this knowlegeable video. God bless your household.
I have a few things to say.
1. Sorin explained nicely in the video that the chip will not fry because the current is not high on the pins and that is correct.
And that Programmer is beautifully designed and does its job..
2. as far as CH341A modification is concerned, it is not a matter of higher voltage in chip frying, but in data transmission on that pin.
5V (4.82V) and 3V (3.28V) voltage injection affects the data transfer pin (read-write)
It is known that voltage and frequency affect data transmission (Example: higher frequency affects data transmission, incomplete transferred content on the chip can occur), which also happened to me, but not always.
So it's not about frying the chip, but a higher voltage on the data transfer pin.
There is a lot to explain depending on the use of the Programmer and its connections, i.e. the resistance of the accessories (Examples: a clip with a longer cable or the length of the cable by connecting to the chip)
3. You don't need to modify CH341A works perfectly.
If you decided to modify, in my opinion, the best way was modified by Georgdev. You can look at (eevblog.com-forum-repair-ch341a-serial-memory-programmer-power-supply-fix)
with this modification, you regulate 3V and 5V on the switch.
when it is put on 5V switch it is in factory condition..
Sorry for my bad english writing, Regards..
I have a question
If I need to reprogram a Lenovo Bios Chipset, do I need to purchase any program/firmware in some scenario where the exact firmware is not available?
Phenomenal explanation, I bought the same complete one but I was years behind in studying how to program it now, I am an amateur but you have to check the bios IC datasheet and the clamp or socket have specific positions because usually these products do not come with good manuals.
Hi Sorin! I'm so happy to see that everything is back to normal!
glad to see the channel is back hope you are well Sorin 🥰
Thank you a lot for this videos evrey time we learning new things from you 💪👍
Just purchased the Programmer from Amazon to make it a little easier for me to program the chips.
I do have the means to air unsolder the chips but hopefully with this programmer this will cut the soldering step.
Great video.....
👍
Subscribed! You saved me from stupid unnecessary modification.
Thanks for this video. Im a lot more confident after watching.
Happy cleared review, happy Christmas in advance ♥️
Wishing you and your family a very Happy Christmas.
hi sorin, were happy your channel is back...
Thank you just got mine today and i didn't change anything and i will use it the same way you just did :D
Nice wish you a happy and Merry Christmas sir
Great video thanks merry Christmas
Happy Nativity Sorin🙏🧡💚
Great video
I did the mod before your video but thanks for sharing your knowledge
Super useful video, thank you very much!
Merry christmas sorin 🎉
nice to see you again man
Merry Christmas, we need a real expert like you Sorin to clear the confusions on our community
real expert🤣🤣🤣🤣🤣🤣
YOU ARE THE ONE SIR...LOVE FROM INDIA
awesome video. thanks for the explaination
Great, I needed this on a bios for an old laptop that's a paper weight and its bios has been corrupted for years, I will try it, very informative piece here Sorin. watch your youtube channel all the time and never miss an episode. Greetings form an old Romanian from Sydney Australia that left Romania in 1960, I was born in Petroşani and still can speak a little Romanian, but I forgot how to write, so sorry that I can't write to you in Romanian as using google translate is just not on, keep the great work up but please stop the bogginess 😁😁😁 with not replacing capacitors 😁😁😁👍👍👍
and finally ordered. Many thanks
I have this programmer with green pcb...is very good! With neo programmer v2.xx is excellent tools. Programming avr processor...arduino and other !
But tnx for every video who you make i learn from you a lot
Nice explanation !
Merry Christmas and Happy New Year to all
This is a great video we can use this.
Perfect explanation..!
Good luck sir 🎉
A great little programmer, the only two issues are speed (it’s a little slow) and the black peg/clamp is terrible. The pin are so hard to line up and get a good connection. I ended up buying the blue pegs which worked so much better! I have bought a faster (more expensive) version to speed things up. But the one you tested is a great device.
Could you post a link for the blue pegs?
what pegs are you talking about?
Mulțumesc Sorin
I have used this with success and have never modified it, as the seller from Alpress told me that no need to modify. I even sent him link which said it had to be modified. His answer was they have sold so many and no need. Trust me friend, he said lol. Good one and have a very happy festive seasons.
Hey man, thanks for the knowledge!
I have a question, I am about to do my first spi programming on a lenovo Ideapad 3 (got my brother's computer bricked by a wrong bios update 😮💨) and I wonder if there's a name for the circuit you spoke about that may unable writing to the spi chip on-board, because if there is one on the motherboard I'll have to buy soldering tools also and finding-out if this circuit will be a problem before my spi programmer-arrives might save time.
Welcome back ❤️💙
Great video thank you
great video! Where do you find the bios file? And what is his format? .bin?
What programming software are you using? I'm new to EEPROM programming and I like that interface a lot.
Thank you
First time watcher. Liked and subscribed. I like your manner of teaching.
The "Mod" refers to using the programmer for automotive stuff that requires 5v instead of c.a 3v in order to work. Modding them allows you to read/write 5v stuff. Hence "no need" to mod for laptop use - but need to mod for automotive use.
Ah.... Chanel is back... good to see you sorin... Don’t Scare us again
My boss bought one of this for us to use in the shop when we were just getting our feet wet with programming SPI chips and such - it paid for itself tenfold ! Soon we were fixing laptops and TVs with corrupted firwmare like there was no tomorrow.....and I never ONCE even thought about the voltage it used :))) It just worked :)) Ok, I never went as far as to program a 1.8v chip with it, but aside from those, 3.3v and 5v chips worked perfectly fine and to be fair, for a good while, I just assumed they ALL chips ran at 5v, until I looked at the datasheet for a 3.3v chip more carefully and had a "whoops" moment, realizing I've been pumping 5v into them for years on end :))) That's when I knew they can take it without a problem :)
Great video Master...as always thank you for the insight!
That little programmer repair me frozen bios on Lenovo G50 80 with Intel I5 processor which I sell later for 300€. Still use HP NC 6320 which had power on password for car diagnosis. Neat little programmer. I read and write everything with clip, no soldering.
What software did u use to program and how did u extract the bios capsule I never got far into repairing my laptop
Merry Christmas too all
I've tested it my self - especially I've bought a 1,8v adapter. The programmer software says "Chip not responding" - in 1.8 adapter, but same chip in same adapter works ok straight in CH341a, so what was the point to buy a voltage converter?
great information do you have a link for the software your using..
Thank You !!!! 🤩🙏
@electronicsrepairschool Thanks for your videos, I'm just an electronics fan and I learn a lot, a pity they don't have the option of translating the subtitles for all the videos.
settings > set english first > then set auto translate > then choose your language
@@suediem9315 Thank you, at the time of writing my message it was not possible to activate it, now I see that it is.
So happy right now👏🥳🥳🥳🥳
Hi Sorin. Can you send me a link to download the program for CH341A . Thank you for your time
Sorin. When the BIOS is flashed, the serial number of the machine is lost or replaced with another incorrect one. There is a procedure for writing the serial number in the bios file.
Do I need to install the CH341 Drivers included in the AsProgrammer ZIP file? Which one should I install, the Parallel one, or the Serial one, or both?
What program you using? I hit the wall with mine... i have 1.3 which is looks difrent than what you show
תודה!
I am absolutely new to bios chip rewrite but I have heard that we should always remove the cmos battery. Is that true? Thank you Sorin. Love your videos.
Hey Sorin maybe we should start over in 2023 with new beginner series. Best wishes!
TL866II+ is the cheaper one the works without issues and there are monthly software upadates ... I use this one only as a COM interface to program seagate disk paramaters ( smart etc etc )
Hello @Electronics, what programmer are you using i don't recognize it.
Crăciun fericit
I've purchased the programmer from your Amazon link but I cannot find where you download the software from :(
i love this chip just add a 74ls244 between spiflash and the chip you can use it as level chifter with 2 regs 1.8 and 3.3 volt
HAPPY CHRISTMAS to you and your Family SORINand i have also got the same programmer and found no Problem with it but thanks for the video as it confirmed my findings
Mrs. Sorin pin number 1 red wire should connect it on the gate ??
Hi one question, with this program could I updated a bios? Example my mother boar is a z370 and only have the F5 bios version, and my cpu is a 9th gen, but I don't have a 8th cpu gen, and its support page says that if the mobo is updated to the f10 will work with 9na gen
What about 16 pin chips? Is there a 16 pin clamp that works with this, or only if I solder the chip directly onto the back of the programmer?
Salut! Am o nelămurire, am luat acel programator dar fara acel adaptor albastru deschis pe care il vad acolo si l.am conectat la un cip MXIC de 1.8v, inseamna ca am "ars" sau nu cipul ?😊 Mersi !
hi sir. what is voltage jomper duty ? i mean , in what condition should they be , 5 or 3.3? tanx.
Everytime i connect it to the bios chip i get the usb disconnect sound in Windows. I did everything right and the 3.3V fix but i dont understand what i am doing wrong.
I just flash a Asrock bios 1.8v no problem without 1.8v adapter. thanks.
Sorin = perseverance ✔
Hi can I know the software you are using for this bios programmer? Can u leave a link on this because I used it before but I think my software is wrong I can't programme a bios chip. Thank you and happy new your
I tried this exact method, verbatim, to read a MX25L3206E BIOS chip, using the same exact programmer, ribbon connector and orientation etc. It detected the right device, and even partially read the data, but stopped after only reading 6% of its contents. I disagree that it's impossible to kill the chip with 5v, because after this attempt, the supply is now being shorted to ground through the chip. Prior to detecting the device, the default supply was 5v.I think the safest method is to prevent the 5v completely, when reading or writing to MX25Lxxx, but obviously not for all EEPROMSs!
Merry Xmas..🇵🇭
I think you're right
