- 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.
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. 👍🏻
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.

You are the only youtuber who explain things in a cohesive and efficient way very rare in this industry and I'm learning a lot from just watching you and explaining how things are done. 100/10 sir, greetings all the way from the Philippines 👏
What I realized in your presentation is a different solution. I have learned a lot from watching your videos. I have never seen anyone on youtube who offers a solution like you. Congratulations and stay with you

I like the way you deliver speech and most amazing with lyrics and descriptions, thanks go on👍👍
Nice job. Unfortunately in my experience this doesn’t always work, but can save some of them if not too completely shorted
Basically what you did is bashing Rewa face. lol
Thank you. Love your channel
Hello from Philippines 🇵🇭 Lockdown.
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 🇰🇼
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.
@@Radek__ why didnt he replace the short capcitor instead
outstanding explain and research about the problem ....mind blowing sir god bless you
very well said sir ive learn a lot of things b watching ur videos u gave as hope for us newbie to explore things in easy way i love the way u delivered ur teaching its easy to understand u deserve a million subcribe

Great job and diagnostic strategy
you are best bro :) Hello From Turkiye
This method sometime works, but most of the time, no. Usually the baseband CPU shorted beyond repair.
Another really great video and something new to learn Thanks for the video . Jd from UK
You teach me something and I m very proud of you..tq sir
This guy is genius ..Thanks For The Great info ..love it 😘
I think Apple engineers turn to him for tips.
Excellent explanation.
Pls lim i would love to undergo ur onlime trainning to understand ur SOPs how do i go abt it. U helped me solve a backlight issue following ur SOP. I did try based on my knowledege but afyer watching ur video i solves the problem. So pls whats it gonna cost and how do i go abt it.????
Thank you so much for your video! i learned new things & you explained in detail. Kudos!

Absolutely very good information 👌👌👌👌
Very helpful video every content is vital ifornation.
Thank you so much for the information ill do it with this video when i have the same issue because my iphone 7 unable to activate was overheating so bad idk why but yeah i will try this info ❤
Nice bro. Thanks so much
Bro is Chuck Norris of iPhones. Apple kneels for him fopr advices when something goes bad at the R&D dep. :)
Wow it's amazing, good job Mr. Thanks for the solutions 👍. I'm new subscriber, any friend suggest to watch your channel, so it's live to watching and then wow amazing tutorial. Thanks a lot again 👍
Why the 2.2k resistance?
Good question !
To protect the ram line .
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
good job man! u r the best! very cool organized video
Real Master! Love from Pakistan
Another great video, thank you for sharing it.
Really good info no one can check like this
Thank you for the video

You are genius brother❤️
100 % correct..success with me also...thanks bro
Why didnt he replace the short capcitor

Saya dari Indonesia, apakah bisa repair cpu baseband short iPhone 11 pro ?
How much cost? I got same problem on my iphone 7 😢
What is the name of the second software?
From Where you can see the chips design.... alignments
what do u recommend i learn to understand in iphone repairs . pls answer me ur mode of teach is different
Nice
So.. if cpu bb short, why device cant go to menu??? Just stuck trun off
master
What about if Amux1 line of bb cpu is shorted?
Hello. I followed the step in detail, but the power baseband does not output any voltage. Can you help me?
In a scale of 1-10 u r f*cked😂…… even though it is 2 years later
I have the same problem, sir, the SMPS line is short-circuited, I installed a 2.2k resistor, but the result is "error device didn't accept baseband data", please respond, sir!
Do u offer online trainning/ i want to improve my troubleshooting skills and i have been following ur SOP for a while and ur technics are great. So do u offer training im in Nigeria and what the cost
Hi I’m from Philippines, I also have that same problem, i cant find any phone repair shop that can fix my iphone baseband problem but I’m not sure already because i tried to activate my iphone 7 using my WiFi but it doesn’t work and I didn’t tried to activate it using pc or mac, if ever that it won’t work, can you repair my iphone also? If ever, how can i contact you?
