Nice
Bro what software do you use to open a Network locked phone??
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
Fera!!
Goog work

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℃.
Looks so easy but when you try, it's really hard..
Still practicing!
Needs a lot of patience.
But I can still learn a lot !
干得好兄弟！
Soooooooooppererrrrrrrrrrrrrrrrr
I wish i have that kind of hand
so easy 😁

Hello I have one Question ?
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 :)
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 solder paste you use what brand
For the detail fo the solder paster, please check this link ( shop.rewa.tech/detail/low-temperature-lead-free-solder-paste-oem-new.html ) as a reference.
How much hot/tem or air???
Rewa👌🏻👍🏻😘
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
I thought it was the ram on top, cpu is the bottom layer? Am I wrong?
Hi sir
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
Broken CPU possible to repair and get the data from iphon
А ОЗУ получается не нужно катать? Как без подогрева они сняли проц не «завалив» оперативку?

OK. Then please fill the application form here: bit.ly/2VDxJ4c.
I took my broken iPhone to a phone repair company, they told me the cpu is bad. Can a cpu be fixed to retrieve data?

щас пионеры посмотрят это видео и побегут валить трубки,подумав что все так просто и легко сделать)
I can't didn't find your number
I had iPhone 3Gs with same problem, just dead already. Should i reball the cpu ?? 😂😂😂
Try to troubleshoot before reballing CPU.
😘😘😘👌👌👌👌
First!
Any company’s in uk doing this ?
Got a dead iPhone 6 anybody fancy the challenge of repairing it
Me watching 2024😂
Hope it can still help you acquire new knowledge.

1 unlike by apple employee
Two apple employees now. 😂😂
I dont understand a damn thing!
Unprofessional! No need to break the shield to remove U2 and even tho no need to replace with the new one to see if it’s ok! Just remove it and turn it on if it’s the u2 then the device turns on and enters a loop, anyway you could realize the cpu issue by measuring the feedback line when it’s not connecting to the cpu right then fb line is 4V !
Can you explain a little more this:
"anyway you could realize the cpu issue by measuring the feedback line when it’s not connecting to the cpu right then fb line is 4V !"
Thanks
