- Here we have an iPhone 12 Pro Max that has no power and not charging. The problem was a shorted capacitor on RF board (C1800). I just removed that capacitor and now the phone is back to life. The hardest part was the reballing process and cleaning the boards. That unleaded solder is not good to use on consumer devices.
Some of the tools and supplies i use all time
- Sugon T26 soldering station with JBC C210-018, JBC C210-002 and JBC C210-020 tips
- Gordak 952-A (I'm using this only for it's soldering iron)
- 8858 Hot Air Station (no name)
- Seek Compact XR Thermal Camera
- Sunshine DT-17N Multimeter
- HY3005D Power Supply (very old)
- Kingbo RMA 218 Flux
- Baku BK-227 Flux
- Cynel Soldering Wire 0.5mm and 0.7mm
- Mechanic XGS40 158C Solder Paste
- Relife RL-404 138C Solder Paste

I discovered an easy way to open the new iPhones 12-14. All you need is a suction cup and heatgun. You just prep the bottom area with some heat for 5-8 seconds. Then put suction cup at very bottom edge and start pulling with firm steady pressure and HOLD the pulling, for about a minute until you see the lcd gap open. Once you see the gap, you use sesame blade to open the rest.
Merci beaucoup depuis senegal 🇸🇳

What schematic are you using sir?
This one: english.wuxinji.com/
which prob to connect to the line and which one to the ground ..always confussing
If you inject voltage - always red probe ( + ) to line and black probe ( - ) to GND. If you measure in diode mode always red probe ( + ) to GND
Great video❤🔥 What flux are your using?
Thank you!
I'm using Kingbo flux - here it is: www.amazon.com/Kingbo-Flux/s?k=Kingbo+Flux
@@PhoneRepairRO Thanks
👍
Nice !! how much voltage did you apply?
Hello,
I injected like 2v at 2amps.
Isn't it generally necessary to replace a defective capacitor?
Not always. This one was on main power rail VDD_MAIN. There are alot of other capacitors on this line!
Awesome hands thanks
Invisibile one 😂😂😂
which stencil u use?
It is something from QIANLI - 10 in 1.
Hi! Amazing video! Do you have a repair shop?
Hello! I don't have a repair shop. I do this as a hobby!
@@PhoneRepairRO 😔 Looks like these iphone12 are all garbage. Mine doesn't power up and overheating. Tried everything. Don't know if I bring it to Apple if they will warranty it
@@rickmucci4785 You might have a short on some nand line or somewhere else.
If it is under warranty go to Apple ( i hope you have some backup on icloud or on your pc ) - they will give you another phone.
If not, go to a repair shop that do microsoldering ( all will say that they do microsoldering - look on reviews ). Where are you from? Maybe i can recommend you some repair shops!
Have a nice day.
@@PhoneRepairRO Thank you so much. No warranty, just heard that since they had problems with these things that they might do the work for free as a recall or some but I think it won't happen in this life time 🤷 Montreal,Canada. Can it be a capacitor?
@@rickmucci4785 If they don't have a recall program, not a chance!
It's a 50/50 the thing with the capacitor, but you say that is overheating - that means the phone try to power up till a point - there are some power lines that come on after you press the power button / or you promt to boot with the charger - so it might be a short somewhere.
You can send your phone here www.ststele.com/contact-us/ , the shop is in Sarasota / Florida / US (much closer to you than Europe / Romania).
Jason is a guru in this industry, is the guy that made Apple to recall all iphone 6 / 6+ that had "touch disease".
How much to repair
