How to flash is macbook is dead ?

Problem is to find a donor board? Could I take from 820-2796 ??

i will resolder the old smc....i'm going crazy...with this smc i have S5_PWRGD...but smc doesn't work...

i will go crazy...i've soldered another smc..now i have 3,2 on the other side of r8141 but no power led on magsafe... i have even pwrbtn_l 3,4V!!!!! ppbus_g3h is 8,16, PP3V3_S5_SMC_VDDA 3,4 sysonewire 3v (should be 3,4?!) PP1V2_S5_SMC_VDD 0,9 v!?!?!?!? should be 1,2? (line is not shorted)

tried another u7501, still the same

What do you think: is it better to change u7501 with another one or isolate the pin?

Just to understand: why do you think about u7501? I’ve seen that this line goes under smc also!

yes

PM_PWRBTN_L is 0,3v but it should go to 0,3v when triggered! r1405 is 1k, i have 3,3v on the other side...so i don't understand SMC_ONOFF_L. 3,4v SMC_RESET_L 3,2v

ok now with another u7501 i have pp3v3_s5 0v on PM_DSW_PWRGD SMC_S5_PWRGD_VIN 3,3v S5_PWRGD not present 0v on PP3V3_SUS 0,3v on PM_PWRBTN_L

0,011!! FUCK! how is it possible

pp5v_s5 is not shorted.

U7501 basic voltages; 23, 22, 12, 13, 29, 21: 8,5 / 3,3 / 3,4 / 0 /0,7 /3,3

R7563 15 ohm R7560 9,5k R7561 7k same readings of another motherboard

i'm going crazy..i think i will commit suicide....pleas 2informaticos...forgive me for all this chaos.... i have soldered a BRAND NEW U7501...now i miss some voltages...help :( 3V3_S5 not present 3V3_Sus not present P3V3SUS_EN 0v PM_SLP_SUS_L 0v (no short) PM_PWRBTN_L 0 v SPIROM_USE_MLB 0v...

3V3_S5 is 2,8v r7560/1 1,4v r7563 2,8v

this is the voltage PP3V3_S5_REG_R if i put probes right before connecting power supply https://www.dropbox.com/scl/fi/yi41k...pcctutaa4&dl=0 That it stuck to 2,8v..and i think it should he 3,3

i don0t know what to do

S5_PWRGD is 0,3v.... i cant find where to cut trace...i could put some uv on pin 20 and resolder u7501
