How to fix an iPhone CPU - Full Transfer for Data Recovery

It is great to want to learn microsoldering, but you DO NOT PRACTICE ON CUSTOMER DATA JOBS. A shop in Florida (who I shall not name), decided to try their luck on this water damaged iPhone 12 pro max. They were unable to split the sandwich and they overheated the CPU. When this customer called me, she was desperate and crying because she wanted her baby photos so badly. When I told her that the last shop overheated the CPU and potentially killed her board, she was devastated. I very much hate having my customers cry.

The worst part about it is that this would have been an extremely easy job had it not been touched by an amateur board tech.

It is even likely that this was THE 5G ANTENNA and didn't even really need board work.
This is why it is so important to learn how to properly diagnose, rather then just going straight to your worst assumption. I often preach diagnosis over CPU swaps, etc. But that also applies to simpler things like board splits, especially if you are an amateur.

There are a lot of resources for learning microsoldering nowadays. That has its benefits but also its drawbacks. In many ways, it has given the false assumption that anyone can do microsoldering when I don't really believe that is the case. It takes a particular type of person to really become a master at microsoldering. It is also not a quick or easy thing to do.

People think that if they spend $2k+ going to a week long course, and then another $2k buying equipment then they have everything they need to do the work. That is not the case.

YOU NEED PRACTICE.

Some people have only a few hours under their belt before they start taking customer jobs. Some people have 30 or 40 and think that is good enough.

Conservatively, I would say I solder about 4 hours a day, 5 days a week. Some weeks it is much more, but there have been times it is less. That is 20 hours a week. But that is every week for the last 7 years. That is 1000 hours a year, or 7000 hours over the last 7 years.

When people ask how I know what to do, or why I don't mess stuff up, it is because I have put in that time. So again I will say:

YOU NEED PRACTICE.

I bought my own water damaged devices and painstakingly tried to figure out what I was doing for an entire year before I ever touched customer devices. That is because I didn't want to ruin other people's property.

Anyways, sorry for the long rant. It is just sad to know that many wannabe techs ruin boards when they should have had the foresight to know that it is not as easy a pros make it look.

In this video, I fix the mistake of the last technician with a CPU swap and I secure the data for this grateful customer.

Thanks for reading 🙂

On minute 44:17 was scary when the eeprom blow up. Thanks GOD you got the eeprom on the tower. Good video

i watched a few of your videos and think u explain things well i'm new to this about a yr and a half i done through hole soldering and sm back in school porter & chester learnning computer electronics, went to pitney for about 17 yr, pm machiens, learning the ipads, but this is very interesting i have watched videos so much to get what i can from them, hours and hours and more hours going back and a very lot of notes, i went deep in this hobbie and now need to learn more, thank you and to all who take the time to support the customer they keeps us going

hi can you share your temp and air in hot air for reference, and also the brand of you reballing stencil it very precise...thanks

[ajaysharma-guif]

Nice job 👌👍❤️
BTW r u work from home?
Your daughter is so cute 🥰

[sudheerm.s]

Next time please mention about the temperature and air at the side of screen for reference n educational purposes

[carmelorossitto]

It's an extremely difficult job. I wish I were at your level

[sudheerm.s]

Is the old board reusable by uv curing ?.

What happened there.
Peeled of pcb layer?

I think that beautiful little girl want to heat CPU again😂😂 but well done bro you are my inspiration ❤

[massakutv]

how many degrees Celsius does the blower heat? Hello bro, I'm from Indonesia.. Your video motivated me to learn to use the CPU👍🙏

[chamberlynibenyeh]

Im having issues improving my reballing skills, when taking out CPU I loose pads on CPU itself and not on the board. I use a SUGON 8620DX. Heat 380°C and Air flow 30... Pls are there any recommendation or Guide u can give to

[kingragnar]

sir please I need help. I have an iphone 12 pro max and sometimes appears like pink squares for only a second and when I try to play pubg mobile it crashes so much like every 3 minutes less or more it keeps crashing again all the time, and I'm not able to bring it back to apple for many resons. Can you help me with an app on the macbook or PC to solve this problem without opening iphone hardware parts ?

Hi Aaron what is the CPU holder and stencil you are using please?

[daviddenson]

Wish you had shown how to unsandwich the logic board

[daviddenson]

How did you power up the phone? Was that the positive lead of the DC power supply?
Also, what do you connect to the phone to get to the data? And how?

[tonyboytv]

sir may i know the temperature used to remove the cpu

[marsss]

My iPhone xr has been serviced by the baseband but the technician said there was a crack in the baseband, and the data could not be copied, how should I do it? Thnk you

[teamgiveaway]

What solder paste do you use to reball iPhone 12 & 13 sandwich board?

[teamgiveaway]

What stencil did you use for the CPU reballing?

[Bc-vbdo]

bro how temperature delodering this cpu and air flow?

[iphonemechaniCc]

How much heat and air have you used to remove the cpu! You are not here to teach you are just making your content
