    Macbook A2251 SSD Not Detected

    Hi guys, as the title. It turns on, charges, etc, but boots to the flashing ? folder. Once in recovery mode no drive is detected. I also noticed that the wifi signal is very weak. If it's over 2-3 meters from the router it will lose connection.

    No signs of liquid damage, or anything obvious. All power rails are present with voltages and diode readings matching the boardview. Same with the following SSD related points:
    I2C_SSD_SCL
    I2C_SSD_SDA
    P0V9_LX0_SSD0
    P0V9_LX1_SSD0
    PP2V5_NAND_SSD0
    PCIE_CLK100M_SSD0_23_N
    PCIE_CLK100M_SSD0_23_P

    Sound like a NAND/controller issue?

      Doesn't make sense to me. SSD controller is the T2 and it needs the SSD to at least boot. I would probably try a DFU restore.

          Thanks for the help, I'm not familiar with Macbooks. I do have a working A1706 so hopefully that will be capable of the restore, will give it a shot tomorrow

              Macbook Pro 2019 A2141 NAND Shorted
              by tech_guru
              Hello. If you could please help me understand what I am doing wrong...

              This model, Macbook Pro 2019 16" A2141, 512GB, EMC 3347, with T2 Security Chip, had 4 NAND Chips shorted in 1 wing (U9100, U9200, U9300, U9400) and it has 1 more in the 2nd wing (U8600) BUT NOT shorted. All chips are TSB4227 TOSHIBA-KIOXIA SN4192TWNA12014 BGA110 128GB. I got 4 new nand chips for 1 wing and programmed them by specific position of course with JCID P13 programmer.

              I also replaced the tps power ic for the ssd.
              Now all rails come up, including the ssd rails 0.9v, 1.8v, 2.5v....

              MacBook Pro A2251 - 820-01949-A not charging
              by MikoMiko
              Hello everyone, I have a MacBook Pro 13” 2020 (Four ports) (Model A2251 with the 820-01949-A logicboard). It had some minor liquid damage but I carefully cleaned the logic board with alcohol and let it dry as needed. Now I encounter following situation: The MacBook does start but the Battery is not charging when a cable is plugged in any of the ports (I use the powerbrick and cable that came with the device). It had some charge left, so I could safe some data, but I was limited my the 13% and the speed of airdrop. The liquid-damage is almost only limited to the side of the logic board where...

              Macbook Pro A1990 - Battery not detected after connector torn off
              by silver60618
              Hi Gang, Im working on Macbook Pro A1990, the battery connector was torn off during friend trying to replace battery. I soldered on the connector back, and created traces. The battery does charge (according to amp meter), and does power on battery only. But the signal detect line maybe done incorrectly, and the macbook shows "X" over battery icon, and "Service Recommended" on new battery

              Can somebody point me to which of these connector pins is responsible for battery detect/data line? Pin 4 on schematic had a nub on the trace, im not sure if that is important,...

              Macbook Air M2 A2681 NAND upgrade error 35
              by kuba2102
              Hello people. I have undertaken an upgrade from 256GB to 512GB. I have another A2681 board that I sourced NANDs, resistors and capacitors from. Yet when I try to restore the firmware in FDU mode I get the error 0x23 (35) (error formatting the NAND). Could it be the faulty NAND or I have missed something? Thank you...
