iPad Rehab

Legos. Truly Legos.

I might have to fix a water-damaged keyboard in the morning if I keep crying on it like this.
For those of you who follow me (ibjessa) on Instagram, our new YouTube channel, and the iPad Rehab Facebook page you've watched these last few days as I've finally mastered bga repair. (Those square black chips that sit on a ball grid array)  

I struggled with it for a long time, and a turning point came when my good friend Louis Rossmann got tired of listening to me complain about it.  He made a plan to pack up his own personal Hakko 801 hot air station--that he uses daily for his own repairs---and send it to me for a weekend just to try it.  I had the supposedly better digital Hakko 802, and was finding it hard to believe that it was so out of calibration that it wouldn't do bga at all.  He was so serious that I thought he might *actually* send me that thing, so I bought one on eBay.   BGA was instantly within reach.  Quality equipment that won't let you down is everything.

A few weeks with 100% success on my bga repairs, and I graduated from the small U2 ic chip to the bigger PMIC chip on the iPhone 4.   I did an iPhone 4 data recovery job, and then while I had the iPhone 4 stuff out, I thought-----I wonder if I could get that original "toilet phone" working again.  I had tried and failed many times.

The original repair story for that phone went like this:
Girls flush phone.
I sledgehammer toilet on the lawn to retrieve phone.
Rice (I was a fool!!!)
Cleaned board with alcohol, new battery and dock connector.
Board turns on, but won't charge
Head to and learn about the charging coil on the board (Thanks OldTurkey!)
Decide to learn microsoldering--how hard can it be---and order the AOYUE 968+ (which is not a great tool, btw)
Spent a year or so with Filip Pusca online (find talented Filip at
Tried to change the charging coil on this board--it didn't go well.  I didn't know enough to use a tiny nozzle, and had too low heat/flow--I roasted that board trying to get off that coil.
Replaced the coil and board was now dead---I burned the PMIC while making board s'mores
Put it aside for a few months and came back--tried to replace the PMIC.
Replaced it kinda/sorta, but now the Skyworks chip got hot and phone registered a full short.
Made some jumper from a local component by the coil---because I was too dumb to realize that you can revive a corroded pad, it doesn't mean that the pad is gone.
Put it aside.

Until tonight.  Still working under the theory that motherboards are just fancy lego projects, I....
Replaced PMIC with a new one
Removed Skyworks chip and replaced with one from a donor board
Replaced charging coil again
Replaced a few local caps, including the one with the unecessary jumper.

Put back together and.....

It is alive, it charges, it is working!

Which just goes to show that yes, anyone can learn board repair.  And at the end of the day, all phones are just legos. If you really care about a phone, you can switch out bad part for good part, all the way down to components on the motherboard.  It may not always be feasible (avoid those rabbit hole repairs!) but it is possible.

This journey into board-level repair has been such a great ride.  It has taught me just how connected the world really is. Information can flow around the world so easily, making repair accessible to everyone.  So many of us are natural-born "fixers"
Even this news of the resurrection of my toilet phone, one small day after Easter, has already traveled to my microsoldering family--to Texas, California, Moldova, Australia and back---yet the sleeping family upstairs is yet to know.  How fitting, that an hour before this repair tonight, I spoke with Kyle--iFixit founder.  Now I am more excited than ever to join the iFixit team to help encourage the DIY and Pro communities to keep stretching the boundaries of what we can accomplish in repair, and sharing what we learn with the big wide world.  What an adventure!

Now off to dig up that old iFixit thread and update this repair--it's fixed!


Go Back

Thanks for your great work - Samsung phone repair


I'm really truly inspired to learn and do what you do... so i am thinking to buy equitment like yours jessa what brand and model no. Do you use and tools as well if you don't mind me asking pls. And thank you


I take a bow for such strong dedication to repair even "almost dead" hardware. That's way beyond my actual capabilities.


Thanks for your great work and inspiration to so many


Hi,i can see your good jobs,can you help me with a video repair of iphone 6 no sim solution




Jessa, I came across your youtube channel that leads me here.. I watched your water damage video and I learn more than what the instructor thought us in the repaired class I went to last year.. Thank you. keep up the great videos. I'm more confident now that I'm going to take another look at 4 water damage iphone 4s I have setting here that I bought.. Will post my results on your channel comment area..


Persistence! Great Job!


I second your opinion.
Great job... Im gonna blow some dust off my haako and go fry a couple boards again :)


Probably the most rewarding repair of all times, right? So nice!


Dear Jessa,
You, Louis and oldturkey are a inspiration to me. As someone who started with a simple iphone 4s screen repair because my girlfriend broke her phone to someone who can build a phone from scratch from orderd parts and any repair that comes inbetween. And now my goal in life is to learn microsoldering. I live in in Holland and there is only 1 comapany that does it but without gaurantee and absurd prices. Please carry on posting as any time i see a video from one of my guru's i just have to fix something.

Kindest regards from Amsterdam,
