Hi, I have an iPad Pro 11” (3rd generation – model A2377) with a non-functioning Face ID. It consistently displays the message: “Move iPad higher/lower” during setup. When inspecting the TrueDepth system with an infrared-sensitive camera, I noticed that the dot projector is not emitting any...

Same behavior with the new daughter board. I suspect the issue is related to the sleep/wake sensor, which doesn’t seem to be working correctly. Example: When the MacBook is closed and I plug in the power cable, it automatically boots up. The display doesn’t go to sleep when I close the lid...

I took the measurements again and updated the values above. (with keyboard and trackpad connected) The diode value for SPI_IPD_MISO_CONN is 0.100 lower than the source data you provided. Other than that, everything seems to be OK. How would you like to proceed?

Device was water damaged at Trackpad connector, Keyboard daughter board and Audio area (Audio already fixed).

Hi, I have a MacBook Air M2 with a non-working trackpad and keyboard. I tested it using a known-good trackpad and keyboard, but they didn’t work either. Based on this, I suspect a logic board failure. Here are my measurements so far: UT3A0 Output: TPAD_KBD_WAKE_L = 1.8V UT320 Output...

NAND BOM group: 1TB_KX

After replacing all four NANDs with known good ones, I was able to successfully restore the device via DFU (using Finder, not Apple Configurator 2). Note: The logic board was installed in the housing. A power cable (external charger, not a USB port from another MacBook) was connected. NAND...

Maybe Firmware related? SPI_NOR? Edit: I have removed UN100 and UN300, power cycling stopped - so maybe bad soldering job (blame on me) or one of the NANDs is faulty as well ….

I have checked those pages and compared them to the donor board (from which I pulled the NANDs). Both boards now look identical, except for the missing NANDs on the donor board. What am I missing? What else should I check? What about the power cycle topic? It's still occurring. Furthermore I...

Page 98 and 99 are for the BT/WIFI module. What exactly?

The NAND pages show some configuration resistors at the bottom. Where do you see them? Are you referring to the ‘Board Rev’ table? (Page 152) Furthermore, I have checked page 108—RP003, RP004, RP005, RP010, RP011, RP012, and RP013 are also present on the donor board, even though they are only...

It seems like the board was ultrasonically cleaned due to water damage. Yes, the battery is good, and I have also tested it without the battery. I noticed that this MacBook had five NAND chips (UN000, UN100, UN200, UN300, and UN500), which seems unusual for a 512GB model, doesn’t it? (Edit: In...

Hi, I have an A2442 (820-02098 / MacBook Pro 14 M1 Pro) that is power cycling every 3 seconds. The USB-C meter shows the following sequence: • 5V (PPBUS_AON = 12.26V) • 19V (PPBUS_AON = 11.96V) • Power cycling occurs (PPBUS_AON = 6V), and the cycle restarts. I have noticed that...

Seems like something in WIFI chip area is draining the battery, see here: (Thermal picture was taken while MacBook was in sleep mode)

Hi, I have an A2337 (820-02016) which is draining the battery while it is sleep mode. (Like 20-30% during the night) Note: - Battery has 100% health, so basically new.
