This is a general query arising from a specific issue. I'll try to get to the point as quickly as possible, but I think some preamble is needed. The specific issue: My Note2 has packed a sad: boot stops at logo screen. None of the fallback boot processes work either (recovery mode etc), except the last, which includes the factory reset option, which I haven't yet tried to activate. Now, most of my data is on the micro-sd card, but some remains locked away in the internal storage (e.g. app-specific data, and undoubtedly a few things which I won't realize are gone until I need them and can't find them). I know that this data will be wiped by a factory reset, and I accept that this is the likely outcome, but a couple of things I've read have got me thinking, hence ... The general query: Is it possible (e.g. using Odin or Fastboot, or otherwise) to gain low level hardware access to an android phone from an external device via the OTG port, and then do a memory dump of the internal storage (to a clean sd card maybe, or out via the port)? And yes, I realize that recovering any usable data from such a dump is far from trivial, but at least it's only a software problem after that (and likely quite an instructive one). Given that I've never used either product, my reasoning, based on their descriptions, is that: 1) if Odin allows reloading the OS, it should also allow loading of, say, a custom minimal OS designed simply to accomplish the memory dump; 2) if Fastboot allows the phone hardware to be controlled directly by commands sent from a remote device (or have I misunderstood the description?), bypassing any software on the phone, such commands must allow the necessary access. So, is it feasible, or should I just grit my teeth and run the factory reset?
