#32This is a joy to watch. And this person had better stay anonymous. If Apple knew their identity, they'd be excommunicated on the spot.
It's a company with a website, https://www.batterymall.com, described on their YouTube channel:
> KingSener is a registered trademark of our company in China, United Kingdom, United States and European Union. Our company specializes in supplying premium quality laptop batteries for global customers. We have more than 10 years experience in this industry，cost-effective products for customers and also produce customized products (OEM/ODM) as per buyers requirements.

#33I started watching this assuming that the nand is either slotted in or would be de-sodered. Then the micrometer scale calibration gauges for the milling machine came out and I realized what was about to happen. Quality work!
Definitely a "wait where is this going" moment.
Had no idea CNCing away BGA chips is a thing

#34The video omits crucial details aside from the physical act of removing the original and soldering the new NAND. I know for a fact failing to copy original details results in failure to restore iOS with specific error codes, so I wonder what this video did. I've successfully done this many times back in the iPhone 6S days where the original chip was desoldered, read by a Chinese-made reader, and finally the identifie…
I suspect they intentionally skipped that part because it contains "proprietary" techniques they don't want to make public.

In theory, it would be possible.
In practice(as a bare minimum):
- you need to patch the firmware for the new display
- patch out the radio
- ? patch battery capacity or re-init
Not sure how much of the patching part is possible atm.

... As I said... it's not enough to just plop on a new chip from somewhere else and do the standard iOS factory image restore process without extracting info from the original and putting it in the new before soldering. This information prior to the milling is omitted from the video.
I’ve seen several videos by reputable fixers that demonstrate empty NANDs working fine with DFU factory restore. Same situation on Mn MacBooks. Would be weird in the actual mass production process if the flash would need to be pre-programmed somehow; one DFU process IMO must be able to do everything needed.
After watching a couple of videos, that works with some older versions of DFU software and not new ones. Might be an arbitrary restriction by the DFU update software rather than the hardware. I'm sure they know this and work around it of course when doing these FLASH swaps.
Also if there are two flash chips they need to be installed in a certain order. Not sure of the rationale behind that precisely. I doubt it's a hardware difference.

#37This is cool, no doubt about that. And fascinating due to the sheer complexity and amount of fine detail work required. But. Uh. For all that work, Why not upgrade it to an amount of storage you couldn’t otherwise get? Or at least max it out?
Because... When you bought the phone 2 years ago you didn't anticipate you would need more than 128GB of storage?

It can do this without even removing the LTE radio.

#39This is impressive, but... what is so terrible about a Micro SD slot? Knowing, of course, that Apple products don't have one as a rule but my current (cheap) Android phone still does, and storage expansion is a matter of spending $30 at Costco.

They show it getting restored to factory image.

There's a tool for that (many, many of them), both software-based and physical-based tools that can copy out the SysCFG block and write it into a new chunk of flash.
