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 all, got this board not powering on. it has 4 usb-c port and at start i got this situation:
1 usb of each side was on 5 volt and 120mah drain, and 1 usb of each side had 5 volt and 480mah.
after replacing 2 usb of same side cd3215C00 (should be ok) i had 5 volt and 120mah on all port, but on other side of replaced cd3215 i had one port not worning if cable was inserted one way ( work just opposite side cable)
after another inspection i see one usb not giving PP3V3_UPC_XB_LDO and usb-c getting hot, so replaced the other 2 usbc and finally now i have... -
dear fellow tech enthusiasts, I would appreciate your help ! I have an 820-00850 here that died on a squeezed/shorted charging cable.
I found several shorted ldo's on both U3100 and U3200. I replaced them with cd3215c00 ( originally c00Z )
D3301 was shorted, removed without replacement for now. No other visual / obvious findings. ports look good.
4,86V / 0,23A on usbc meter and ppbus 12.28V, ppdcin_g3h 5V and pp3v3_g3h 3.3V - all ports/orientation. Nothing obvious on a thermal picture, only t2 warms up to 35Celsius.
1V1 LDO missing on u31/32... -
Board couldn't boot due to corrosion under UB090, stuck at 5v 20-30mah. After cleaning that up the board boots and charges, 20V on all 4 TB ports.
Trackpad and keyboard currently don't work due to a failed battery swap that left gouges in the trackpad board exposing traces. Touch bar doesn't work either, haven't started troubleshooting that.
USB devices aren't detected on the JB500 connector. any orientation, either of the ports. Tried known working flex connector. When using an ammeter I see no power flowing out to the USB device, when connected to J3300 5V 200mah goes...
