Nice video, it was a challenge and i like challenges :), one of the comments was right, don't heat pmic with heat gun cpu is on the other side and on the 6s it offten shorts, next time use iron with big tip and add solder then lift it the same way you did. Good luck for the next one ;)
Thank for the video. But do you remove C2103 and FL4620(and after it), L5408_RF(and after it), C3008 or even U3000? - its all on this line. And there is a reason to put 3V on this line and see what is heating up of this componets.
Good job, but you forget check other side board, you have line pp3v0_tristar go to R4040 and R4041 and ic u4040 for light control, maybe there is yours short :)
Hi have you ever come across iPhone 7 where the touch wasn’t working at all? The phone had boot-loop, I replaced the audio IC, made jumpers and put a UV mask, the phone switches on but it doesn’t have any touch ( I have tried a know good lcd). I don’t know if it’s related to the audio Ic replacement because the phone wouldn’t switch on before the repair..
I’ve been looking for 512gb 3D nand for the iPhone 7 and I cant find any nor I don’t know what patter this chip uses. Any way you can point me in the right direction?
I ended up with a similar board malfunction on my behalf. My goal was to unscrew the logic board and test it with a new battery since the battery it came with is stuck to the logic board I thought gee, its easier to remove the logic board, I didn’t do it on a ESD surface it was on my bed. and when I connected to logic board to a working battery I forgot to reconnect the power button connector sleep/wake button. I only connected the battery D.C. connector. I’m afraid that I did something really bad to the LB, the smoke came from the front of the logic board under the top metal heat shield cover plate. Not the bottom of mother board with sticky heat shield stickers. There was no sign of water damage, I should’ve took a picture of the mother board before I worked on it to have a record of working components from the before and after the smoke appeared. Did I mess up because I failed to connect the power, sleep/wake button connector to the mother board after I had connected the battery D.C. connector to board?
@@scoopof3d could you elaborate since we are here. I called repair shops but they would look at the board. I asked if they could let me know which parts went bad. But they denied me.
imgur.com/gallery/ULLRoNA lots of missing pads when I used the hot air gun to lift off the old pmic. When I lay the new one down and use hot air to it, will that flow down and create a working circuit or is this board done for?
i think your problem caused by overheating cpu . next use heatsink need skills to replace its so i advice you to remove pm ic using big tip of soldring ion and solder its with heat gun .thanks for sharing video
Reitz this is a heatsink its suck almost the overheat so you need to pay it . Cosmos ® 8 PCS Copper VGA RAM Cooling Heatsinks cooler + Cosmos Cable Tie www.amazon.com/dp/B00637X42A/ref=cm_sw_r_cp_api_tUeUAbMVPR651
Lets see if i got it right. Everytime i need to use heat, lets say to remove NAND or PMIC i stick this heatink to the cpu? Just like a computer cpu with thermal paste? Thanks!
Też się zastanawiałem dlaczego nie ma ochrony CPU. Być może, że w przypadku gdy na procesorze wciąż jest blaszka a pod nią pasta termoprzewodząca, wtedy nie potrzeba dodatkowej ochrony?
Hi, sorry to say this just like a big brother do not share faulty information ! but what I really like about your try is disconecting the PP3V0_TRISTAR connection between Tristar & PMIC ! I like this Idea but all your steps were not true and wish you best of luck trying to get it OFF DFU mode and make it boot again sorry to the dislike ! (I like the cutting idea) !
I did not say FAKE ! I said "Faulty" I mean "misguided" how could it be true to apply 400c to a PMIC underneath it CPU ! that's what I mean is not true your overheat killed CPU I wish you can show us the device working with LCD for at least 10 minutes (I do not mean any harm) but I need to see it works that's all as I said before I extremely like cutting trace idea it's just awesome!
The video shows the phone not working. I never said it worked. 3v0 tristar had 3V again, but the phone didn't boot or wasn't recognized by itunes. I run hot air at 370.

I hope not to have to replace pmic ever again ;) But thank you.

An absolutely 1st class job sir.well done.keep up the great bids.
What about the CPU?,pm ic is always a nightmare to everyone,any way that was great! keep going man
Love your approach to the detail. Thumbs up. Keep going. Liked and subscribed
You should have removed the CPU shield from the other side to let the hot air flow.
agree hehhe
Good job, but you forget check other side board, you have line pp3v0_tristar go to R4040 and R4041 and ic u4040 for light control, maybe there is yours short :)
Awesome video man!
this one the best video because of long video to understanding ,,, thanks man
Your welcome.

I've tried to look my self but cant find any.
I am big fan of you your working style so good thanks again
Was this repair successful?? I don’t see you turn on the phone?
Why not put voltage into the line to find the short?
Did you have some amper before you changed or totally was 0 Amper?
what about the jump .. any short with lenght or by magic not!!

I think the lcd wasn't connected right and it was the fuse blowing up.

@@scoopof3d Smilar to a broke inductor the L4000 out to Chestnut_SW into SW pin U4000?
Hi there , what make the kills or break the PMIC on cellphones, thanks
Good effort man
Nice try bro the PMIC nightmare everyone 😓
Yeah :/
Wha type of lens do you use for your 6300?
Respect only so hard work.
from where to find these diagrams sir?
Highly unlikely it was PMIC mate more likely u3000 to gnd or even another line but good try :)
PP3V0_TRISTAR line was shorted. After removing pmic short was still there :/.
I think you've caused shorts under the CPU or even killed it. You might try a reball but it's a pain in the ass ;)
I thinking about doing it since there isn't much to lose.
Good job man
How many degree temperature use
imgur.com/gallery/ULLRoNA lots of missing pads when I used the hot air gun to lift off the old pmic. When I lay the new one down and use hot air to it, will that flow down and create a working circuit or is this board done for?
how to safly remove ic.. smd heat air .........
so finaly this phone not trn on??
No :(

Could you explain more about that heatsink? Thanks!

Reitz yes if you want iwill send you all details no problem you welcome its will safe work 100%
no damge ram or cpu or others ics 😉

I respect completely 😌 cuz I know how its hard
Wht is tht green gel?!
UV ink

wish you good luck with that 6S plus hope you can fix it !
change GPS IC U5411_RF
Where are you men
That PMIC sucks
To replace
Yup :/ Owner said its ok to try. Cant win them all.
fake video 😡 time wasting
