I forced it into DFU mode using the jumper method. No DFU mode. Voltages present in the coils. I compared it with another board that works.

Without the F7000/1 fuse, it's 12.3V. With the fuse it's 4.8V. PP3V3_G3H_RTC_X 28mV | diode mode 0.390v I'm using the original 96W charger.

Hello, I have this mac that was working, but stopped turning on unexpectedly. There was no contact with liquid. It replaces the U7000, Q7030/40. C7030, R7030/40 are okay. Voltage: I removed F7000/01, in the PPVBAT_G3H_CHGR_REG mesh there is 12.33V. In diode mode on the PPbus 0.275v

Hello, I have this mac that does not turn on. According to the customer, it was connected to the charger and did not turn on after a lightning strike. There is no sign of burned on the board, but I identified that it has already passed through another workshop. A CD3215 was replaced (U3100), CPU...

Yes, only when I select the "Revive device" option, and the loading bar gets stuck at the end, along with the error message on the other mac.

Hi, I have this mac that won't turn on, however it has all the SSD voltages and the trackpad clicks. When I put the mac in DFU mode and select the "Revive device" option, I get a "Missing data volume" message. The customer authorized the "Restore" option, and although the mac displays the apple...

It was a BIOS problem, thanks for the help. It was a bit tricky to find a working version, I had to transplant the ME region of the client BIOS to a new BIOS version. I will provide the final version below.

I removed the battery, same behavior. No history from the client. L7650: 5V L7610: 3.3V L9900: 1.35V L9810: 0.8V L9820: 0.8V L9740: 0.8V L7310: 1.1V (should drop below 1V?) L7930: 0.9V L7810: 1V L7150: 1V L7130: 1V L7110: 1V L7230: 0V L7210: 0V L8100: starts at 10V and drops slowly to 0V every...

Hello, I have this board that is not turning on. The first LED is stable, the second one turns on for about 10 seconds and goes off. After about 3-4 seconds, the second LED turns on again, but this time it stays on. I honestly don't know if this is the standard switching behavior of this board...

C9101 was missing

Good afternoon this mac I can not format the SSD, already tried good Bios, but without success.

L9400 0V, no pulse LB700 0V, no pulse L7960 0,96V L8000 1.001V L7900 1.21V L8050 1,02V L7270 1,14V L7220 0V, no pulse L7210 0V, no pulse L7410 0V, no pulse L7420/30 0V, no pulse L7700 1.06V L7600 5.14V L7660 3.42V L7030 13.2V L3500 5.24V

Good afternoon, this mac shows no signs of oxidation. Ja put another Bios, but not solved. L7030 = 461 L8410 = 931 L7660 = 408 L7600 = 447 L3500 = 181 ALL_SYS_PWRGD 3,26V PPDCIN_G3H_CHGR = 20 V PPVBAT_G3H_REG = 13 V PPBUS_G3H = 13 V PP5V_S4 = 5,1 V PP3V3_S5 = 3,3 PP3V_S4 3,3 P3V3G3h = 3,4 V...

Exactly. I tested it with two Topcases and it works perfectly. Shouldn't it be 1.8V on pin 20/21? I am testing with the Flat touch disconnected and the LCD of the BAR connected.

J4402 Voltage Diode 20 2,99 0,412 21 2,99 0,411 22 5,13 0,451 No critical software error occurs.

This mac has a bubble on Flat J4402, I replaced the Topcase along with touch bar, in testing it worked, but then it stopped. I replaced the Q4400, but it didn't work. The LCD in the Bar Works.
