Thank you, Appreciate your help.

is there something else I should do regarding the NAND REPLACEMENT? Should I get a different set of NANDS ?

I have a stable 3V8_AON. However, PPBUS goes high to 12.0V and then drops to 6V or so and quickly goes high to 12.0V. At the same time, I noticed PPDCIN goes up to 20V and then quickly circles down to 5V, which corresponds to when PPBUS circles down to about 6V. I compared diode mode...

Hello guys. Please I need help with a 16-inch 820-02100 board. The Board was working but would restart immediately after the OS started to load, it is the same thing when I try to press and hold down the power button to access recovery, I tried to restore the device in DFU MODE on multiple...

As always, thank you so much, I always appreciate you. will do and feed back

hello guys I have got an 820-01041 with backlight issues. I have replaced the screen cable, and the screen display connector but I still do not have a backlight even though the screen is fully functional, from what I understand, there's no load on the voltage output line, hence the reason for...

Thank you so much for your help

Yes, I tried a USB C cable, but it still 5V, with the same behavior, also when I compared diode mode measurements on the SSD rail with a known working board, it checks out.

Thank you for responding to me. I tried with both battery and charger. When I got it from the client, connecting mag safe 3 has no LED.

Thank you for reaching out, Yes I tried both options : the error I get is 4042

Hello guys Have got a 16 inches M1 Macbook Pro (820-02382) that is stuck in DFU MODE. The Logic board is spotless( very clean ) I went over the board and I couldn't find a short, PPDCIN is 5V PPBUS is 12.32V. PP3V3AON is present, an not sure exactly what method of troubleshooting to follow...

On a side note : Does the machine booting into DFU signifies that all CD3217 are in working conditions? In other words, if I have 5V across but am able to boot the machine into DFU , does this means , my issue isn’t at the CD3217 level ?

Yes : SSD was replaced on one , so what did, was I removed all the SSD chips , but board still boots directly into dfu

good day guys , please I would like to understand this concept, am having two separate machines have started to experience this , one was an A1990 and the other one is an A2141, is this caused by the T2 itself or its PMIC? Please guys , am not looking for a specific solution, I would like to...

Thank you @tcampbell34, not only one Machine? Have had more, and my fellow technicians about 2 shops forwarded me the same issue, one of them just left here not too long ago with the same issue on a 2018, A1990, myself have had it on a MacBook Air and a 16inches and an A1990

I did , I erased the SSD in DFU MODE , but still get the same error message, also other technicians have sent me pictures of the same issues .

Good day guys , I hope you all are doing okay , a big thank you in advance to all of you, for always readily providing support here . So I have started to see a wave of MacBook Pro come through the lab for macOS installation, T2 based macs only , and they are always stuck at a message that...

Good day guys Have got an 820-00163 with no PPBUS voltage , there’s no short on the PPBUS and 2 confirmed isl replacements but same results. Have only got 1.5Von PPBUS. initially, the isl was burnt, so was replaced and also current sensing resistors values were off , so also replaced. The two...

Good day I have a MacBook pro 15 inches A1707 (820-00281) stuck on 5V. One of the ports stays steady on 5V, while the other 3 ports are fluctuating, which I thought suggests the one that is stuck on 5V is the issue, hence the reason why I replaced it 3 times with 3 different known working...
