Ok so what Jason has shown here is a more accurate representation of what actually happens in real life instead of these 5 min DOOF DOOF videos well done Jas the Ace ;)
And great video Jason! I think I've watched everything you've published at least once or twice. Really got me to get out of my own comfort zone and just start learning. Now I'm doing audio IC'S, NAND reballs, and running jumpers like a pro! Thanks for everything!
I seriously enjoy this unedited videos much more than if you turned it into a 20 min video, so many details lost hahahah
Would like to see you continue with it Jason, as time permits. Life comes first, bills to pay!
This is a great video series, you should keep making them (as long as you can, of course). Many people like myself are starting to practice CPU reball and every experience, every last bit of info is so important
7am enjoying the vid! Like I’ve always said keep em coming. Much support here from South Florida!
For me at least and I know for other techs we would love to see the end. At the end of the day if you dont try you fail and even when we fail we learn. By posting you teach and share the journey. I love your style, skill, enthusiasm look forward to the next video in this series and more of your everyday repairs.
Have you considered investing in a 5.5 or 6.6 digit multimeter? Not sure if this method would even work on something as tiny as cell phone guts but I can usually find shorts on pc board with my 5.5 digit meter. Mainly because there is a big difference between reading 0.000 and 0.00089 ohms. So if I have something like 0.00088 from ground to v1, I'll start looking something lower. Sometimes old tricks are the best tricks. Good luck with that phone.
I actually laern a lot from these video. Thanks Jason this is my first comment to your videos though i have watched many. keep up the good work we appreciat you
Cool video. Thanks for the walk through. Even failure can teach us something !
All cool! Dont give up love watching you try !
Videos like these are honestly almost more valuable than the quick successful repairs. That is what the most beginners will start out with
Nice job Jason. Keep trying with this board to make it boot. You have to desolder cpu again and find the shorted pads. Measure the sorted line (on board and cpu) before reball again the cpu. The second attemp will be easyer. Good luck! Thanks for sharing your "FAIL" videos. Apple logo on the next video!
Jason, you are great at what you do. Hello from Pilot Knob,Mo
Super Video.Danke!
Patience is a virtue that Jason certainly has ! I'm guessing that you are learning a lot win or lose.
really liked the video ,, since it shows the reallity...not fake edited perfect ending videos,, thanks jason i learn lot from your videos..youre amazing,, god bless you!!!.... was it finally repaired ?
Another Great Video. Thanks.
Amazing my Jas,
Luv
You man 😘
Jason: *puts 2 volts on a .9 volt line*
Jason: *bumps off 10 caps from the board and doesn’t care*
Jason *scratches the board in multiple places*
Also Jason: well I need this board to work at the end!
I'm gonna wind up re-re-balling this one but for now, it's gotta go on the shelf for a while. I'm just gonna have to know if it will boot after fixing my little solder bridge. :D
@@ststele Guess who placed the tweezers on top and squeezed?
STS Telecom try, fail, try, fail, try, succeed!
New T shirt "I need a NAND job"
Pure gold right there! :D

monthy python
That's is really a good one, most people won't get it while for the "insiders" it is a pretty flat joke
hahaah
Remember that what you consider easy to do now was difficult before. There's a learning process for everything; once you're past it, the difficult will become easy.
Thanks for uploading that , youllbe improving that skill every time you attempt it
Failures only mean you’re about to learn something. Keep at it. Also a quick way to determine which side of a coil a short is on, is to remove it and diode mode each pad. You’ll know what to chase
Hi jason! the camera that focus on you is recording at 30 fps and the one that focus on the blue matt is on 60 fps right??... why?? i need to know!! haha great video!
i learn more idea on this trouble shooting thanks to your video
unedited videos are the best, I'm sick of perfect videos with successful endings, in real life there are fails and from fails we understand better and learn faster
".....guess we don't need those caps either" The ultimate in kicking you while your already down... lol
That scratches are pretty helpful I think, to get a feeling for if you touch the pcb at all and how hard you push, and also just shows how steady and sensitive your hands are.
But the "Oops, I guess we won't need all the caps..." was so funny 😂 You are always so cool from the outside, are you the same on the inside or do you count all the bad words even in languages you never heard of? 😄
Like the others said to learn, but also just for satisfaction to see this work, every second is important, so don't think things like someone loses the interest, as more complicated it is, as less you need to cut the video, side effect is you safe a little of the time on cutting you lost on the repair and don't need to watch the misery again 😄 easy jobs can be short.
Loved your honesty. I tried four-time reballing A11 and A12 cpu with no sucess yet. i don't know what I'm doing wrong.
This is why I love watching your videos you don’t edit out the mistakes out and it show how difficult this actually is and that it takes practice even being skilled doesn’t mean it’s any easier always learning something with you factual information great work Jason 👍🏻👍🏻👍🏻👍🏻
continue with my idol Jason
Brill video Jase. Though 400mA isn't a short if you're psu is set to 3.2A?
You may have not been successful, but glad you posted the attempt anyway. I wonder if for really tough shorts like this you could use something like an old Keithly 196, which can be found pretty cheap on ebay. It is able able to measure down to microvolts, microamps and milliohms. With that you could follow the resistance or voltage drop along the traces to the location of the short.
I like the way you troubleshot this (i mean without the 2 volts) anyway nice try Jason. Without failure we cant succed. Keep in mind. Thank you my friend, as always Great Job
Like a baby learning to walk a couple steps before a wabble & fall...but they get back up & try again before success keep at it bud (you know the mistakes you were making but were getting urself wound up i do the same & i either walk away or i make a silly choice...I've tried to stop allowing the rushing into a mistake & make the right choice when i see it)
I think it was too much flux under CPU that caused the error but you seen that😉
Please keep it up bud & remember to take a breath when u get that urge & it will help, we're all on the journey with you man stay strong & pay the bills looking forward to the next 1😎
Keep going my friend 👏👏👏👍👍🎉🎉🎉
Not a fail jason, the board layout is so crushed up that even a tinyest imperfection can cause a problem.
Keep going, you will beat the little shitbag lol.
cool setup
On your microscope view, ask Paul Daniels about his setup, he has a lens which replaces that tube thing that goes between the camera and the port on the microscope. Its still not perfect, but is much better.
Jason, you need to stay professional ,you are a very clever guy I fully enjoy your video's but please don't rush any work you are doing for the benefit of us watching!
Always produce the best work you can even when practicing soldering techniques, knocking components off putting them out of alignment does not advertise your work too well, we who always watch you know your work is normally excellent but for the new watchers and potential customers who may consider sending you work may be put off.
Keep up the excellent work, cheers
Try also do give temperature from soldering and hot air, will be really help a begginer like me :D
its very hard to reball a chip, especially CPU, at least you have tried, no matter the outcame .
Good job
The fail doesn't matter
Try and try you will overcome
Don't worry gohead
The next video Jason finds a sturdy tree, buys a rope and starts to learn knot tying. Find a less stressful job instead. I like your videos.
LOL..I've had many a conversation like that with Alexa.
But Jason, those GLON videos make it look REALLY easy!
@Kevin Jalali Haha I already don't! Interesting to hear from someone that knows though.
Any details of your experience? He does make some good tools 👍🏻
Kevin Jalali Interesting. Could you explain why it was useless?
i don’t understand a think youre saying but holy crap this is fascinating
I Like it, you tried it.
Sometime you lose sometimes you win, thats Life.
I learn Form your mistakes, i try.👍
Fix or no fix, try to reparier it.😊👍
Jason did you remove the diode and check it
Jason, did you get that copper wire from an overhead stanchion for an electric train? That's what it looks like under the 'scope. :)
Sorry, but did you say that was your *first* attempt as reballing a CPU? I thought you would have done 5 or 10 practice runs first. When we went for our pilots licence we used to have many practice attempts at all maneuvers, especially engine failures, because there was no way you could get them right first time or even the 2nd or 3rd times. We did get better with each attempt just as you will with each attempt. Do you remember your first screen change? Was it as easy then as it is now? I bet the answer is no. I bet you could almost do them with your eyes closed, hell you may even be able to do them with your eyes closed. Do *not* get discouraged by any setbacks Jason because you cannot buy experience; it has to be earned on each different maneuver or part you work on. Just look at what you have accomplished so far with the CPU. It's just incredible.
In the words of Albert Einstein, _A person who never made a mistake never tried anything new_ .
Google' if you don't shut TF up, I am gonna rip you a new one :)
Remember Jason, a "failure" is just one more step towards a success
3:41 look away children, we've got ballage squeeze all over the place
Oh thank goodness, someone is _thinking of the children_ (and in a good way).
You need a toneohm! Sensitive low-ohm meter will tell you when you’re closest to the short.
More please!
I like nitro cold spray idea
Nice try bro good job 👏 👍
👍❤Super ❤ 👍
no no no jason keep to the easy jobs lol.
Google needs a re-ball.
Just noticed, you have a QUICK hot air station on your bench, but cheapo listed on your Amazon affiliates tools list. Why?
Total accident. I’ve been using the quick for about a year I guess but at some point in time, I copy and pasted an old description block. Now I have recent videos with old tools listed. I have to make time to go back through and update all my links and video descriptions anyway.
Continue please!!
I am big fan
I have iphon 7 plus. It sometimes flickers while doing screen lock on and off. What may be the problem? Plz suggest..🙏🙏🙏🙏
Have you tried restoring your iPhone to factory defaults? If that doesn't work, try a new screen that you knows work, or put your mother board into a different working housing. If it still doesn't work, you have a logic board issue
What the name of that software?
Now you got two ripped pads on your nand!
scraping the CPU pads is not a good idea
i want to see more plz.
practice makes perfect!
Soon I will post updates to these failed CPU videos. :-)
@@ststele Cool bud, will keep my eyes out for them.
I was doing my first repair yesterday. It was on an iPhone X with a short on Vdd Main and at one point I accidentaly gave it 5V (instead of 4V) from a Power Supply with max Current of 12A :( It let out some smoke and I pulled the connection well before a second passed but now it takes 0A... Does someone know what part was most likely to burn through and break the connection?
First try a new dock, battery and multiple charge cables. Still not charging:
1.) Visual inspection of the battery connector.
2.) Diode reading on the VCC Main line at the battery connector.
3.) If "OL" or significantly lower than .350, move to the Charge IC.
4.) Visual inspect Charge IC.
5.) If there IS no visual damage to the IC or surrounding components, remove Charge IC.
6.) Check Diode readings for all pads. If there are any abnormal readings, test components on that line.
7.) If readings are normal replace Charge IC.
8.) If the device still is not charging, replace Hydra.
Shouldv checked resistance under nand
I would look at it with a thermal camera - but don't have a single working ios device within reach... Reballs NAND so he doesn't have to stand up. Spoken like a true technician haha
oof and nand removal didn't fix the short -_- F in chat for STS Telecom
Literally LOL'd at this. I wound up using a thermal camera on the very next phone. A working ios device was closer than I thought. Wishing I would have bought micro usb version!
@@ststele usb c version ? its buggy as hell im regretting getting mine lol :D
just put a wood stick in it and call it i-scream

Remove the shorted cap!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
wassup Jason!
Hey!
heya I can "see" that you would lose some steam I would if I was you but I also would try to vigger it out wen I would have some time left so to say because if you would succeed that will put you 2 lvl's higher
Nice try Bom back to life is waiting
Short pmu… reball
This parcel short, because the voltage not drop at all.
please whrere schematic
🤔🤔🤔🤔🤔🤔
😅
I said before the cpu is shorted itself
Stop trying just pay $ to learn the correct way
When I have time, I will get back to this. There is not only one way to do it and paying money is not the only way.
@Ahmed Alijarah....Jason is too polite, so I'll say it. Shut the F..k up!
I like your videos but after this one i would not give you my phone to repair sorry so unprofessional.
