Hello does anyone have the UF260 firmware for the A2338 M2 model?
The logicboard # is 820-02773.
The USB-C chip for the A2338 M2 is a CD3217B13 and not CD3217B12
is the UF260 rom the same as the A2338 M1?

Hi,
Here it is the original rom from this macbook mother board with a very strange behavior. I included the A1990 UB090 file that I found here in the forum, thanks for that. I can see that the content of the files is different, probably too different for just being than mine got a bit corrupted.
The behavior is that al four USB C ports negotiate the 20V completely fine and the computer boots. Connecting a USB hub, the sd card reader works, the Ethernet port works, HDMI works, but connecting a simple mouse does not work. The working functions of the USB Hub mentioned only work on the... -

Hi everyone. I need a help with this Mac, please.
The logic board shows no signs of life , is clean with no liquid damage, and is stuck at 5V and 0.294A on all ports.
DFU attempted, but it stalled halfway through the system installation.
Mac turns on with a working battery, but doesn't charge it.
With a Working battery the voltages are 20V at 0.0300a
PPBUS_G3H - 12.28V
XB, XA, TA, TB are all measuring same voltage.
PP20V_USBC_XB_VBUS - 5V
PP3V3_UPC_XB_LDO - 3V
PP1V8_UPC_XB_LDOA - 1.8V
PP1V8_UPC_XB_LDOD -1.8V... -
Hello friends, it's been a while.
Model A2141 came to me for repair.
I confirmed that there was a short in the ppdcin line and that the capacitor was blown.
All the short line capacitors seemed to be in bad condition, so I replaced all c7043, c7024, c7026, c7027, c7029, and c7042.
The short is caught and the power is turned on.
However, when the power is turned on with the battery installed, only one charging port works and the other three display 20V but 0 amps.
If you plug in the charger when the battery is not installed... -
