I would like to take the opportunity to invite again all members to consider a donation.
All members should be aware that there is a real possibility this section of the forum to be closed because the volume of uploaded files is increasing every day, the number of members in it also, but only a few people donate.
Every day we delete files from the old threads in an attempt to save the situation, but this will not solve the matter. I urge everyone to be more active, everyone can afford a small donation, let more people get involved, only this will save us from the possibility of running out of space to store data on the server!

Hello Vesko356, I read all the warnings and also read about the ch341a, I saw that you have to lower the voltage to 3v, but the question I need to know is.
I'm going to remove the chip from the board and solder it to the ch341 adapter, by doing this I save the file and send it here to unlock it? should i lower the voltage to 3v or can i use 5v? I did not find anywhere on the internet anyone doing the unlocking with this programmer.
I'm a little lost, if you can help me!

Yes.
The answers to all your questions are given in the topics I mentioned above.

Once again the answers to all your questions are given in the topics I mentioned above.

...
Likewise, if you want to modify the BIOS to remove a password, it must be done with an external programmer.

When flashing a BIOS always make a backup first. Take 2 or 3 different dumps and make sure they are identical.
On Windows, you can use the command "fc /b" to check if two dumps are identical.
Make sure that the dumps looks good, i.e. not filled with 0x00 or 0xFF. After compression, if the file has a size of only a few kilobytes, the EEPROM was most likely not read properly.

Additionally, please read the FAQ at: https://www.badcaps.net/forum/showthread.php?t=98665

1.1.1.6. CH341A
Supports I2C (24-series), SPI (25-series).

This programmer is not recommended but it is the cheapest programmer available.
It has several shortcomings:

• Limited interfaces support, only SPI and I2C
• Several different software with varying level of reliability and ROM IC support (especially troublesome with 128Mb and larger ICs)
• Several different hardware design, some of them having design defects
• No proper detection of communication issue with the ROM IC

Available software include: NeoProgrammer, Colibri, AsProgrammer, Flashrom…
Read the guide there: https://www.win-raid.com/t4175f16-GU...rogrammer.html

If you have a black PCB, it is very likely that it needs to be modified for 3V operation instead of 5V. Failing to do so could damage the ROM IC.

Watch the instructions there:

Re: Please Help Apple macbook pro A1708 EMC 3164 efi Lock

Hello friends, good morning, I recently acquired an ezp2013 programmer, I removed the MXIC chip and put it to run, the programmer program recognizes the type, brand and name of the chip, but when reading it, it only comes out as ff without any code, I did something wrong? because he recognizes that the chip is there but does not read the files inside.
