ok after I did a lot of research and testing I found the issue was that the programmer don’t make a good contact with the NAND just put on the NAND piece of paper and close the lid on it and it’s work perfect now Thank you so much:)

Sure its show the message on all the nand that I put in it so I tried another pc and different usb cables same result

yep

I’m trying to figure it out but still same problem...

Yeah in know that😊 I’m using from board that have nand shorts on R side and I’m thinking the good one from L side

I’m using with adapter BGA110, date is ok and I’m working on A2141 512gig and I’m removed nand from same model and capacity, And I’m trying to make all of the nand with the same calculation

Yep its show on p15 screen the model: TSB 4227 and 128g and when I reading this show bin files

HI all, So I bought also the p15 and it’s not working like it’s supposed to be, it’s just read the nand and can’t write data to the nand all the time its show(nand repair failed) I tried different nands and still same issue, some know what is wrong with it? thanks

R8260 removed same result, 0.161 u8100 in place

Thank you very much i test the correct value on good one and the correct need to be 4.337k ohm and diode mode 0.434 L8260 as been removed: pin 1-167.1 ohm / diode-0.163 pin 2-261.7k / diode-0.526

hello, Macbook M1 Pro (82002100) came in with water damaged and completely dead liquid around U8100 i put new one from older board and then the mac boot normal, but U8100 getting hot. after several tests on coils find the L8260 have low resistance 166 ohms and diode mode 0.163 looks like m1...
