G900P Deleted DCIM Recovery

Hi,

I accidentally deleted about ~7 months of pictures/videos from my phone. I have spent about a week trying to recover them, and am pretty confident my specific questions have not been posted previously (or if they have, they are still unresolved), or I would have found them by now. But I could be wrong! I apologize, please point me to any relevant threads if that is the case. I tried to do my due diligence in reading about forum rules and whatnot as well, but I am so exhausted from the past week of ~interneting~ that I could have missed something. Please correct me!

Anyways, I am pretty confident I was able to image the mmcbkl0 thing using ADB (using this). When I run the .raw file through testdisk I get two partitions that show up as Mac HFS that could not be recovered. I have no idea what is going on there. Photorec finds a bunch of stuff but none of my deleted images. Also, the files it does find I am completely unable to open. I've looked into figuring out how to mount the drive in Ubuntu (running 12.04) but I get rather confused.

I also brought my .raw file over to Windows and tried to use this guide (from xda), but I could only mount the drive with NTFS or FAT32 and I am pretty sure it's supposed to be ext4. Regardless, the Recuva program gets hung on ~analyzing files 20 of 30~ or whatever. I let it run overnight and the "time remaining" estimation just kept going up so I killed it.

I also tried everything on just the userdata partition (mmcblk0p26), but it's unclear if the DCIM data is even on that partition. I get similar unrecovered partitions in testdisk. I tried to follow this guide to figure out where my DCIM was, but I am not familiar enough with terminal commands or adb to figure it out.

I am sure you will need a more specific information in order to help me, but I have consumed so much information on android and linux over the past week that I no longer am sure what is relevant. Please ask and I will answer! My phone is currently off, and when I turn it on to hook it up to the computer it's in airplane mode. I had to download busybox to root it, but other than that not much of the data should have been overwritten.

So, if anyone knows how I might troubleshoot the testdisk stuff (my geometries are wrong maybe?), or knows of other disk analyzing software, or how I could mount the .raw file in Ubuntu to further analyze it, or know anything else about where the internal DCIM memory might be, or just have any suggestions they would all be greatly appreciated!

Thanks!
