I'm pretty sure this post is just SPAM.

We are too, but maybe someone will ask a question or provide a solution

Not sure what this thread is about, but if it is useful the S4 do not have any real security and internally it uses a eMMC storage chip that can be removed and read in any commercial eMMC reader via a chip off recovery

No need even to take it out - you can perform ISP on this phone so it will be still alive after full RAW copy

ISP means user would need soldering skills, correct equipment and software and have to know pinout, chip off is much easier option for someone who does not regularly work with handsets for recovery.

I am very impressed with the VR-Table listed at your website, currently any ISP I do is done with wiring but as we get many cases chip off is faster for me!

We usually process cases starting from non-invasive solutions to invasive one - so if we have a damaged phone first attempt is to repair it, then JTAG, SPI or ISP reading, then ChipOff and then if controller is death NAND recovery from eMMC - this is our path.

Performing chip off as a first method is not a good way in my point of view as a first stage. Maybe its faster (no matter if we are talking by coold procedures using sanding/CNC PCB remove from bottom or hot remove using IR/hotair) but not always safe for data ..... what if if you will get disk encryption on Android and you will perform chip off ?? You will need to put back memory to phone. Ofcourse right now it's possible to crack FDE <=1.3 but it takes time and if it's higher then it will be not possible at all. If you use ISP (no matter if you will solder wires or use VR) you will see this very fast since you can scan partition of connected phone and it's GPT to see if UserData it's encrypted or not.... ))
