3 parts exchange: charging dock, speakers, and back panel
My back panel had been cracked for a while, and the speakers eventually crapped out. But that didn't justify the expense. The charger was slowly working less and less until it basically finally stopped. I had a refurbished phone and I think that's why things went awry so quickly.
I quoted a shop, $50 for just the charging dock. For $80 I can get all the parts and tools to fix all three problems. No brainer.
Dissassembly was a bit tricksy as it was my first time working on a phone, but it went off without a hitch.
Reassambly does NOT mean "follow steps in reverse order" unless you remember all the orientations of every part you dissassembled.
There were definitely additional steps in reassembly that I had to look up on youtube, in particular the orientation of the gold pin.
Also the microphone cover wouldn't fit anymore because there was an additional gold part on the charging dock. But the mic still works so who knows.
I kept my screws organized by drawing a grid on paper and writing the step and the size of each screw in its individual cell. That helped a LOT.
Also, if you are new to this, do your best to note orientation of the smallest things you wouldn't expect because ifixit doesn't necessarily provide the information.
Youtube videos, somehow, illogically, will be blurry the moments you need to see clarity, and sometimes go off-screen when something intricate is going on. I.e. if you can FIND the job for the model, don't expect it to be professionally produced.
That all being said, fixing something yourself is doable and HIGHLY satisfying, and I couldn't be happier with my choice. Fiero is a powerful and fulfilling emotion.
