[@paulmendes9315]

Great job, just wondering how he made the first conclusion that the main power IC was not working and from then on how did he know that the clock oscillator was not working?

[@omarlakhdari5186]

I'm not sure somebody can correct me but i think he tried all possible places this problem could be coming from and then he left with this two things so he went for it , i don't think you can check them for sure

[@freakbot1056]

He could've checked for VPH at the power switch line and assumed VPH is ok and good and concluded it to be a problem with the PMIC .

hi nice video. by the way, i found a lot of samsung dead, and current consumption after power On is around 0.3~0.4A , and stay there, not boot up. The CPU is very hot, i dont know if there is short in CPU or because cpu was trying to boot up repeatedly. Can you give me advice ?

[@CINOTechnology]

Power supply short circuit, especially the outer parts such as camera power supply.

Did your all files recovered?

Power managemen unit IC is bad, but first of all, allways need to check crack condensator, varistor, temperature sensor. Vbat, Vsens, V_core, V_reg, rtc frequency, V_sim, thats value need to check before change pmu, need to use osciloscope

Hi does it remove all the data in my phone if i get my old motherboard replaced with a new one or is there a way to replace it but not delete all the data in my phone?

[@CBAN_]

You have to resolder the internal memory onto the new motherboard to keep your data. And if done incorrectly you can damage the chip and lose all data.
