Let's see the device still have any meat left for me to eat or not...
The device has been in many places before my hand. I don't get my hope high if too many attempted repair Baseband before my hand. Let's see...
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 3 года назад

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 3 года назад

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

@icity7341 3 года назад

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__ 3 года назад

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.

@angelodemichele Год назад

I didn't understand, in the video you show that even if there is a short you have 1V stable on the capacitor. Why spin on another power supply? If you do it is because the low impedance makes you sit pp_1v0_smps but in the video it remains stable. thanks for your videos

Just repaired my iphone 8 plus (IMEI doesnt show up) and keep searching for network even there is no sim card. It wokred fine. But the problem is my phone carrier signal is weak as compared to my old iphone 6. sometimes it even got no service in some area. But my other iphone is just working fine when im using the same sim card. any comment?
