    A1990 (820-01041-07) - PPBUS_G3H = 12.23V

    I have successfully flashed the .BIN file to the SoC ROM. Now im getting the following message in AC2 Unexpected device state 'DFU' expected 'Recovery' (Probably forced into DFU mode externally) [com.apple.MobileDevice.MobileRestore – 0xFAE (4014)] Note: SOC_FORCE_DFU and PP1V8_SLPS2R are not...

    A1990 (820-01041-07) - PPBUS_G3H = 12.23V

    Yeah I have tried both. Sadly I don’t have a ROM Reader/Writer, any recommendations?

    A1990 (820-01041-07) - PPBUS_G3H = 12.23V

    With and without battery, yes. I have removed U6950, same behavior. Edit: Just the T2 is getting „warm“. Edit2: In DFU mode SLPS2R and AWAKE voltages are stable.

    A1990 (820-01041-07) - PPBUS_G3H = 12.23V

    I2C_BATT_SDA_R = 1.8V / 0.456 I2C_BATT_SCL_R = 1.8V / 0.464 I2C_PWR_SDA = 1.8V / 0.455 I2C_PWR_SCL = 1.8V / 0.463 SMBUS_3V3_BATT_SDA = 3.3V / 0.900 SMBUS_3V3_BATT_SCL = 3.3V / 0.942 Edit: It can't complete the DFU restore / revive because the SLPS2R and AWAKE voltages are not stable.

    A1990 (820-01041-07) - PPBUS_G3H = 12.23V

    Sry my fault .... Ignore that. I2C_BATT_SCL_R = 1.8V / 0.456 I2C_PWR_SDA = 1.8V / 0.455

    A1990 (820-01041-07) - PPBUS_G3H = 12.23V

    Hi, i have here a „820-01041-07“ with PPBUS_G3H on 12.23V. When I connect it to the charger (just the logicboard / without battery) I’m getting 19.6V / 0.00-0.05A (it’s power cycling). Already tried a DFU restore via AC2, sadly it ends with an error. (T2 is getting warm during DFU restore)...

    820-02020 (A2338 - MacBook Pro M1) - Battery not recognized / No keyboard backlight

    I have replaced the kb backlight and battery sadly ... both are still not working … any idea, what else I can check? Edit: DP900 is fine. Edit2: I noticed when turning on the MBP after 2-3 seconds it crashes and then it boots up again. (I can login etc.) Still strange why it is crashing at the...

    820-02020 (A2338 - MacBook Pro M1) - Battery not recognized / No keyboard backlight

    ALS is working and KB backlight can be adjusted via OS (but can't say anything on the keyboard - have tested it in a dark area) I have found out that "RT046" was blown, replaced it now I have 5.1V on "PPVOUT_KBDLED" - still no backlight. (KB brightness is set to 100%) Bad keyboard backlight?

    Same voltage. If I need to replace the battery ... which do you recommend? (Location: Europe) Note: The battery board was a little bit corroded at F400 area. (Fuse is OK) Edit: Why is the keyboard backlight not working?

    Hi, I have a MacBook Pro M1 which doesn't recognize the battery (0% - Cross Icon). PPVBAT_AON (with charger and battery connected) = 11.96V PPVBAT_AON (without charger and battery connected) = 1.4V PPVBAT_AON_CHRG_REG = 11.96V PPDCIN_AON_CHRG_R = 20V I assume the board is fine because both...

    MacBook Air (M1 / A2337 / 820-02016-A) - Unable to power USB device on USBC0 port

    I managed to open the .BVR3 file which line should I check? How is it called? UPC0_5V_EN? PPVBUS_USBC0 is only 1.7V (UPC0_5V_EN = 0V) when an usb device is connected, PPVBUS_USBC1 is 5.1V (UPC1_5V_EN = 3.2V) with an usb device connected ... which is normal. So I assume the CD3217 (UF400) is...

    820-00850 (A1989) - PPBUS_G3H looping

    Any idea what else could be wrong? Edit: - 5V / 0.16A | PPBUS_G3H = 12.27V - 19.4V / 0.04A | PPBUS_G3H is slowly going down from 5V to 0V Did you ever seen such a behaviour?

    20V / 0-5mA | 820-00850 (A1989)

    No everything looks fine. I noticed that the diode value of the F7000 is 0.350 … compared with a good one it’s 0.460.

    20V / 0-5mA | 820-00850 (A1989)

    History: Water damage (didnt found any signs), one CD3215 area looked like that: Trace on C3115 to PIN12 was broken, fixed it with a wire (PP1V8_SLPS2R is present):
