[Knowledge] Know what you are mounting?
So there has been a couple issues I have seen where people are mounting random numbered "blocks" as read/write....
This may not be good.....
So I offer upon you (the reader) the break out of the blocks!!!
########### Start Break Down ##############
dev: size erasesize name
mmcblk0p17: 00040000 00000200 "misc"
mmcblk0p21: 0087f400 00000200 "recovery"
mmcblk0p22: 00400000 00000200 "boot"
mmcblk0p25: 35dffe00 00000200 "system"
mmcblk0p28: 001ffe00 00000200 "local"
mmcblk0p27: 1b4ffc00 00000200 "cache"
mmcblk0p26: a7c00000 00000200 "userdata"
mmcblk0p29: 014bfe00 00000200 "devlog"
mmcblk0p30: 00040000 00000200 "pdata"
########### End Break Down ##################
Please be safe and do NOT do ANYTHING unless you are 100% sure of what it is you are doing!!!!!!!!!!!!

I provided a warning with this information because i thought it mandatory on some level. The end result (in my head anyways) was for people trying to break into this game would see the above info and further google to find out what each is for.
I guess in a perfect work it would work as "I know i need to do/add/remove xyz file, but the I cannot because it is read only. I just did research and found where it needs to go" Not "hmmm... lets mount block xyz as rw and see what happens!" (hence the reason i said "... unless you are 100% sure...")
If someone thinks this information is too harmful, then by all means request this thread to be locked and deleted.
On the other hand, the fine folks of andIRC are stressing to use their method of rooting so people know what is really going on with their phone. I agree. But part of the root is pushing files to certain blocks. Why those certain blocks? The above info is a good jumping point for research.
Again, I stress: If someone thinks this information is too harmful, then by all means request this thread to be locked and deleted.

You can access this information posted in the OP by opening a terminal shell on your phone or through adb and typing "cat /proc/emmc".
Since the Thunderbolt came out, I've spent hours on IRC helping idiots root their phones... Idiots who either can't read or don't care to read. All of this stuff is not difficult once you learn and if it is difficult to you, don't continue attempting to root or do other things and then come crying to a developer to fix your "bricked" phone.
I believe that everyone deserves a fair first and second chance to learn something properly, which is why if I see someone who is a little lost but has the idea right, I will spend my time teaching them how things work. When you give someone the right tools to empower themselves it goes a long way and generally that person will continue to self-teach and pass his or her information along to the next n00b.-Nexus 4 running stock 4.3 and faux kernel
-iMac 21.5" Early-2009 running 10.9
I was googling all over the place trying to find this info (even had corninacakes looking too :P) and could not find where this info was. Jeffnucci, I actually think it was you that finally steered me in the right direction to find this info (thanks btw )
I thought about giving a brief description of what each block was (cuz i researched it after finding emmc) and adding that, but then figured it would be better if the people researched it for themselves.
People, don't get me wrong, I am ALL about helping!! But as Jeffnucci was saying, don't come and ask for help if you have no idea what is up from down. The people that help need information on what happened to the phone or rom or whatever... That is where a decent base knowledge is pretty much required...
I was hoping (i even had my fingers crossed) that the first post (no offense Droidxcon) was going to be something like: "Ah sweeeeet!!! I've been searching for this info! Can you please tell me where you found it?"
I thought having the knowledge out there was good, but what really thought that having the knowledge out there would inspire people to find out where that info actually came from (cuz this stuff just doesn't just magically appear on the internet when a phone comes out - someone has to find it!)
