Hello , funny thing is all the nand lines voltages are normal .

Hello , I was able to get that macbook in DFU MODE , However , i am getting this error message saying system can not be restored on this device, libusbrestore error:21 -ox15(21) I reviewed all the nand lines and they are all fine as we checked last time , but still getting error while...

ok will try that out and keep you posted.

Right, Do you have any other suggestions other than the DFU?

I found it a bit strange too, but around L 9580 I dont have any nands in that area.

L9580 = OL both sides

I have not tried the dhu mode yet , let me check L9580

Here s what i found out , Diode mode reading L9080/81= 0.346 L9020/21 = 0.106 L9030 = 0.321 LB700 = 0.172 L7660 = 0.378 LA350= 0.008 LA300= 0.120 LA640 = 0.000 LA650= 0.000 LA340 = 0.000 L7330 = 0.011 L7231 =0.001 L7221 = 0.001 L7211 = 0.001 L7420 =0.003 L7410 = 0.003 L7030 = 0.455...

Great , will do that and get back to you .

This macbook Came in , customer stated that Juice spilled on it , I opened and cleaned the board, founds some spots with minor stains and some not fully damaged caps , 20V from USBC meter is present But no fan spins and no boot , please help.

When I try classic method , it would give the apple logo then few seconds it would go to the restore screen again and it does the same when i ran the jumpers method too.

I did , and still going not allowing me.

any words for me ?

I have tried all the DFU method and macbook refused to get into DFU, i am not sure if that could be a nand failure , would you suggest some power rails that could be be the culprit? Thank you

Hello, I am looking for assistance for this macbook M1 Pro came in with water damaged and owner waited till after 3 weeks to bring it to repair , the front motherboard was looking fine but the back of the motherboard was looking terribly bad , I managed to clean the motherboard using OCA...

I am not too sure I meant to type .

Just a quick update, I am too sure if it's the battery or I was testing using a 87W charger , I went back to review the area of U7000 And I proceeded to replace R7061 , C7023 ,C7020 as well as U7000 , Now the device behavior while on the USB Amp Meter is staying without battery disconnected...

any suggestions?

U7800 LDOs, SLPS2R and AWAKE voltages are exact comparing to the schematics, I noticed that C7020/3 Those are looking washed away but not shorted , should i go ahead and replaced them ? also U7000 Was replaced by a new chip , You think replacing it by another one reballed from a Donor would...

Will do that.
