Sir, how much air, temperature and timing have you kept? Please tell me sir
hi , is the CPU you did change that you fix again or new CPU are fixed ?
grand salute sir
It must be hard to repair it when you have to sit all the way back and not get a close look so your head doesn’t get in the video. I had to do the same thing and I nearly broke my iPhone 6 I was refurbishing.
Practice makes perfect. It seems they have many good masters! lol
Ooooooooooooooooosome!!!
Fault finding Great nice 👍👍👍
did you measure every little capacitor for voltage on those 16 power rails? and they all had the value that was saying on the schematics? For example, schematics call for 6.3 on C1719 cap at 1:45 in the video, is that what you got? did you check all 19 caps on that pp3v0_nand rail? and did the same for all the others?
1st comment to idol 😊

Hello I have one Question ?
What bonding pastr are you using?
I wonder that technology still not changed, i showed Nokia UEM Changing method in 2010-11 at my old channel *pakfones old* with basic tools.
But i liked and enjoyed the method of soldering CPU same as i done in past without attending any mobile repair training institute.
2nd
Is the temperature used to remove cpu the same temperature used for removing any other ic on the board or do you go higher for cpu?
Yes it is just use a Heat Tape to protect tge surrounding area

Please sir upload video about basic method of motherboard tracing how do you know direct where is exactly fault plaese tell me about sir I am half technician of mobile
You don't need to trace the motherboard, just search up a schematic of the iPhone you want to fix. Make a list of the 16 power lines, and then CTRL-F to find which parts of the board you can access them. (And of course, find a ground point as well.) Once you find the part on the schematic, find it again on the PCB layout.
Hope this helps :)
Me watching 2024😂
Hope it can still help you acquire new knowledge.
What time is it plaisé
Why do you remove the black sticker from the shield before removing the shield? It will still pop off with it attached
withouth the sticker hot propagates easier, so less time applying hot and lower risk
Juan Issa I’ve tried both ways and there’s no difference in time

Sir i have iphone 7 with baseband ic issue which shows unable to activate screen and shutdown, if i borrow same chip with another iPhone 7 will it change imei? Or i have to program it or anything like that?
Yes, needs to be programmed before install.
@@peverellpoulin5087 do we get orignal motherboard of iPhone 7?? Or if we fix chinese motherboard for iphone 7 will it work smooth like new?
@@peverellpoulin5087Most of the chips on an iPhone are interchangeable. But he CPU, the baseband CPU and the NAND will have to be from the same device since they are encrypted together.
The NAND is a special case. With a NAND programmer, you can read, write, alter or transfer data from the NAND. But dimoly changing the info on the NAND will not work. All three, the CPU, the baseband and the NAND all need to have the same data.

What temp for using the wick to clean pads?
For reference only, with our equipment and environmental temperature, the solder iron temperature we applied is about 400℃.
