The subtitle is available.
P/S: I'm not the one who invented the solution. The trick is from one of China's master many years ago. But I do know how the trick works.

The reason this fails is the feedback circuit and the lack of resistance on the pground pads. If the 1v feedback is missing then the smps5 output rises to Vdd main voltage . The ground jumper is to prevent the feedback loop from failing and bbpmu sending the output of >4v down a 1v0 line eventally blowing the modem.

[@iPhoneServiceMalaysia]

Yes. That’s why I mention not every ground is useless and it’s a prevention. About the Pgnd u said I already cut it out due video I explain it too long. Nice quality comment. This comment will be pinned. 👍🏻

[@iPhoneServiceMalaysia]

By the way, due of that flaw, the damage can be different. Sometimes it lead to us believe this is one of the reason why they started to take Intel Baseband only in certain models. XS 😂

Hi, I did a detailed write up on this a few years back on my blog illustrating the fault condition , solution and mitigation. Great videos btw, keep it up. Its refreshing to see methodology and working conditions being taught in your videos. Regards Dee

[@santho8958]

He is genius becoz mobile technician will understand

[@shaikmultan2830]

You are just Genius man

[@icity7341]

Thanks again lim for sharing actually I not understand why you but resistance 2.2 between capacitor it’s same voltage you are my master lim big van from Kuwait 🇰🇼

[@Radek__]

I think he did it for protection. -if the value of resistor is more close to zero then partial-short after that resistor can heat it too much and beak it or that source line where that resistor is connected can be pulled down with that partial short. So for protection he used high resistance, so even when the ic will do a full-dead-short then it will not affect the source line (on capacitor) because of that resistor and higher resistance.

[@randomdiaries1478]
