Macbook Air M1 A2337 Stuck At 5V

The flash tools I linked earlier are for 4*3mm. This footprint is present on some current iMAC units and perhaps also on macbooks.

Your UF260 is a 2*3mm footprint. The purple board I am fairly confident also supports this footprint but you must solder the flash to R/W the device. Suggest to purchase both zero force sockets as they will be useful. Purchase the 4*3mm and also the 2*3mm and some good tweezers to use the socket.

The schematic is showing indeed a Winbond part @ UF260:

So Winbond W25Q80DVUXIE will be suitable to use for your case + zeroforce or the purple solder type board to work with your programmer. The VCC for this flash is @ 3v3 so no issue to use with almost any programmer.

Be sure to use the full part # before ordering.

If you do not have a proper dump for this chip, post back and should be able to assist from my database of dumps. I believe they are also posted inside the dedicated bios forum.

Yes, all the dumps from that U301 device are also here. That would not be an issue.
I'll get both the 2x3 and 4x3 adapters. And the purple board. Along with a couple chips.
Thanx a lot.

Got the zero force socket yesterday. The pruple board, for some reason, is stuck on customs.
Opened the Mac again and... my chip is 4x3.
Also Winbond W25Q80DVUXIE, even though that's what's on the schematic, is smaller than the one on the board, with those marks mentioned.
Oh boy.

We ordered 1 of everything. Your purple board will work for you (has all of the footprints) but also suggest to purchase the zero force socket for the 4x3. Apple has used both footprints across different models so sooner or later, it will be used.

Yes. Waiting on the purple board. No idea why it got stuck and the adapter didn't.
Will order the other adapter later.
Was hoping to make it work today. lol
Shit happens.

Hi again,
Well, finaly got the adapter. Took the chip from the board but... neither my EZP2019 or CH341B reads it.
Tried different softwares and different settings. No luck.
Oh boy. Do I have to buy a new reader to me able to this MX25U64 eprom?
