Customer came in with computer consistently restarting and shutting down, they took it to Apple and they said DFU restore should fix this computer. Attempted the DFU restore but it refuses to restore. I was curious if his board was water damaged so I took it out and inspected the board, no water damage or liquid damage. Put board back in, battery holds a charge it seems and works fine without power. Tried DFU restore but no avail, it goes into DFU but it won't restore, it resets then it goes to RESTORE screen on computer. But it keeps restarting. I was wondering if his lid sensor is faulty because when I close the lid, it does not shut off and stays on, would the lid sensor cause issues with restoring the computer if its faulty? I am ruling faulty board or bad lid sensor. Would like some input.. so far nothing can be done to this computer at the moment.

Re: A2442 MacBook Pro 14" M1 Pro issue
This is the error message I get when trying to restore.
Failed to restore device in recovery mode, libusbrestore error:21 [com.apple.MobileDevice.MobileRestore – 0x15 (21)]
Researched this, and it seems it is going back into recovery once it starts loading the installer to restore. It goes in DFU then it goes into recovery once it tries to restore. Why is this?Last edited by Stephen; 10-02-2023, 01:08 PM.sigpic

Re: A2442 MacBook Pro 14" M1 Pro issue
read that thread doesn't seem to address a way to resolve this issue.
Going to try MrMacintosh method with IPSW being dropped into DFU. Crossing fingers and making a sacrificial lamb to the Apple Gods.
UGHHHHHH....now the DFU keeps disconnecting and connecting. WTH AppleLast edited by Stephen; 10-02-2023, 02:53 PM.sigpic

by StephenCustomer came in with a board issue, board looks clean, board turns on, he did a software update and he got the infamous Apple boot loop logo. He took it to Apple and Apple said he needed a new board. They attempted to DFU revive restore etc no luck. The board is stuck on the (!) point. I tried DFU myself and no luck. Nothing, board boots up goes into DFU computer turns on with Apple logo when applying the patch and nothing it gets stuck at halfway point and hangs on. I was wondering if anyone has had any experience with this particular issue. Board isn't liquid damage from what I can tell...

by arahbanHello Gentlemen,
I am working on an apple MacBook A2442 board pn 820-02098-A with a visible short on the PMIC U7700 MVK-PLUS as per the schematics
I have a donner board from apple macbook pro m1 A2338 PN 820-02020 and I saw that the PMIC U8100 TMLT46B0-JPE could be a possible replacement for the U7700
Can you please help me confirm if the U7700 can be replaced with U8100 ?
APL1098 is it the same as APL1096
Thank you very much in advanced

by pcbmaniacSubject: Help Needed: MacBook A1278 (3115) No PPBUS_G3H Issue
Hello everyone,
I'm working on a MacBook A1278 with the 3115 logic board and facing an issue with no PPBUS_G3H voltage. Here's what I've checked so far:- U7000 Measurements:
- Pin 3 has 0V, even though R7012 shows 16.5V from PPDCIN_S5_CHGR.
- Resistors:
- I measured R7010 and R7011 with one leg disconnected, and both tested OK.
Based on these findings, I believe U7000 needs to be replaced. However, I have a related question:- If I also decide to replace the SMC, do I need to order it pre-programmed,

by soflesHello there
I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.
I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.
