6 hour data recovery. There are chapters below, for your convenience.
In this video I perform data recovery on an iPhone 15 Pro that was severely smashed. This was around 9 hours of work that I condensed into a 6 hour video. There are many factors that caused it to take so long. Removing the RAM, harvesting a PMIC chip, performing a full CPU, NAND, and EEPROM transplant, harvesting a donor RAM chip, and reballing the RAM even though I did not have the proper stencil.
There is some small silver lining in the fact that I will not have to prepare a CPU swap board, harvest a donor RAM, or harvest a PMIC for any future jobs, as once I have done it once I can reuse them in future recovery cases.
While the video does have the most unnecessary parts edited out, I did still leave in most of the work. This is to demonstrate the real and full processes that were required for this job, as well as to demonstrate the patience required to pull off such a complicated and work intensive recovery.
Some of the time was due to being unprepared, such as not having the proper RAM stencil and not have a new PMIC chip ready. However, I cannot allow these types of hiccups to get in the way of completing the job in a timely manner, so must work around them when I have to.
Reading the chapters below can also help to show how long each section took:
