Re: Apple Macbook Pro A1990 15" - T203 or CH341 with Mina ?
Has anyone had issue with the CH341A adapter writing to the chip recently?
It used to work just fine and now I am only able to read from a chip but not write to it.
The programmer does not report any error (AsProgrammer or NeoProgrammer).
I am currently trying to flash an AT25SL321 and I can read the content and CRC matches every time but writing to the chip freezes the application.
I am asking here as all the info I've found for this tool are in Russian...
I don't believe the programmer itself has a problem. I am more leaning toward a Windows update that broke the driver or something though who knows.
I've measured continuity on the clamp to the pins, under the programmer, and it is connected.Comment

find a tutorial on the internet ... or use the HxD program, enter in it a bios with the password and one with the password deleted after the site .. make a comparison between them and you have the answer ....Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

Mina isn’t the only one. I currently do not use Mina because they are using checkrains source code to crack this which I think it’s fine however, I personally am waiting for one source to update their code becuase it’s easy to read their source code and figure out what they did. Mina however seems to get these things right but it’s a collective of a lot of people working on the back end of checkrain.sigpic

But this is great news now that we can read who the previous owner was. With that being a thing we can now have permanent removal by reaching out to those individuals.sigpic

Brand: Apple
Model: A1990
Board number: 820-01041
Problem: I am not an Apple kind of guy to start with. But I am quite experienced with motherboard repairs in general. So the laptop is stuck with 5v 0.250A and does not negotiate 20v. Same symptom on all 4 USB C ports. When charger is plugged the amps start at around 0.060 then go trough: 0.100 - 0.180 - 0.230 - 0.244 and stay like this. Laptop responds to the power button: once I hold it long enough current goes down to 0.060A and then up to previous levels.
Board clean, no liquid damage, no corrosion.... -

Hi there,
I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.
You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
This daughterboard uses an interesting...04-21-2025, 11:41 PM -
Hi Gang, Im working on Macbook Pro A1990, the battery connector was torn off during friend trying to replace battery. I soldered on the connector back, and created traces. The battery does charge (according to amp meter), and does power on battery only. But the signal detect line maybe done incorrectly, and the macbook shows "X" over battery icon, and "Service Recommended" on new battery
Can somebody point me to which of these connector pins is responsible for battery detect/data line? Pin 4 on schematic had a nub on the trace, im not sure if that is important,...
