Re: Apple Macbook Pro A1990 15" - T203 or CH341 with Mina ?
I wish and hope soon there will be a solution for "newer" BridgeOs , to be broken.
For now i just have it fixed and sitting around doing nothing, because the lock is still on...

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

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.... -

I have changes the keyboard and the touch id. on 14 inch Apple M1 A2442,
"option stuck "
It did not help because the lady was playing intensive games on the laptop : The issue with the Option (Alt) key is related to the Mac’s HID system (Human Interface Device), which manages how macOS receives input from the internal keyboard.
The Option key is not physically stuck. Due to intensive use of the Option key during gaming, the internal keyboard sometimes sends an incomplete input signal, causing macOS to think the Option key is still being pressed....01-31-2026, 07:16 AM -
