A forum thread about repartitioning or cleaning internal memory exists here: http://forum.xda-developers.com/showthread.php?t=2344939
Could a Recognised Developer review this and determine if it really is too risky to attempt? How could it be done? What is the real level of risk?
The posters suggest that just changing to a custom ROM will NOT free up the partition, so reformatting the internal partition appears to be the only way.
Would ADB on a computer with the i545 tethered via USB be a viable way to deal with clearing the partition?
Well for this I think if you decide to try this you're definitely playing with fire. I personally think its a recipe for disaster, but to each their own. You should be directing your question in that thread for support. Xda assist is here for showing you the way, not direct support.
Thank you and good luck.

You may be able to partition your SD card and have that partition be marked as bootable. Tread carefully though if you value the data you have on your phone as anything like partitioning and messing with what's bootable may send you straight to Odin or cause you to reformat your card (or even mess up your phones partition table).
If I recall correctly you should be able to partition your card in cwm or rom manager. That would be a good place to start.
BTW, you may want to clarify your question. On my first couple of read throughs I thought you wanted to boot Linux on your phone. You want a live usb stick kind of thing, correct. Would be kind of cool for fixing messed up computers on the go.

I think the problem would lie around the fact that the gs3 doesn't natively support UMS. If the files are on the ext sd card for the live version than the next step is getting UMS to work. Ever since JB has been released for the s3 I haven't been able to get it to work

Gentlemen
I have found multiple threads covering the aspects of this scenario, but none with a clear conclusion. It might be there, but then i haven't found them.
Long story short, I have been asked to assist with doing data recovery on a Note 10.1 . There is no external SD card, and there is no backup. I´m looking for a small 8kb key file, which was lost during a data crash of another application.
So fare, the task of running a data recovery util on the filesystem (On Track or similar) have been impossible , due to the fact that the device is not rooted, and attatching it as a mass storage device dosent seem to be possible.
From what i found, it´s only possible to get mass storage to work, if the device is rooted, and even so, it will only be the SD card which is accessible
So my questions are:
Is it possible , in anyway to get access to the filesystem, so i can do a scan for lost data?
Has anybody else had luck with retrieving lost data on souch a device?
Thanks in advance
S3 but basics are the same .

Brilliant. This information is so much better then what i found so fare. Thanks!
No support from zeki. They said sorry can't help. And past any warranty to return.
Zeki tablet TBQG884B kitkat 4.4.2
I tried a swap ram thing to try increase memory size/speed.
dev_mount sd card change
I didn't quite know what I was doing. Didn't make a backup, etc.
I rooted tablet with kingoroot it's still on it. So is superuser but it asks to download binary files again, but can't because no sd card mounted. Internal or external.
It won't connect to computer usb debuging or mass storage at all.
I can no longer get into system files file explorer etc., to try to reverse/fix what I did.
It said nand flash something instead of sd in video. I now know I shouldn't of edited it.
Is there any way I fix it. Maybe put a different OS on it? If that would fix it? Maybe something from google/android and kitkat?
It works as far as going online with brower. But not much more. won't mount either sd.
I looked everywhere and trying everything. Please help. Thanks.
It said in video to go into sysytem files and change ...

Hi all, I wish to know what will be the best way to recover the data on my HTC one m7 I before installing custom Rom missed out on taking backup and formatted the SD card partition too, is there any possible solution available to retrieve the data, I'm looking at photos as that is what I have the maximum and of priority and rest all is fine if it doesn't get recovered. Can any one suggest the best option available now?

Sorry but thread closed
I think I have a decent grasp of how the Android system functions, what the partitions are, what's stored on each partition, etc.
However, I've recently been put in a strange situation with my Note 4, requiring me to do a repartition of the internal memory, basically wiping everything and starting from 0. I realised I have basically 0 info on this, except using a PIT file in ODIN, and even then the concept is a bit fuzzy.
I need to understand some things:
- where exactly is the software that allows a connection to ODIN stored? Is it in sort of a BIOS of the phone? Is there an equivalent to a BIOS on a smartphone?
- can the internal memory ever be fully wiped and repartitioned like you can do to a PC's HDD or SSD? If so, how exactly? What are the tools needed? What are the risks?
- I keep reading about soft bricked and hard bricked phones. How exactly does a phone become hard bricked?
- Could you recommend some literature or wikis, forum posts, etc. on this subject?
Thank you very much.

I'm not really a Samsung man but the software used to connect to odin is download mode which I think is the SBL partition (secondary bootloader.) On LG devices it's called the laf partition. That would be the closest equivalent to a BIOS. I found this thread which takes a good look into the partitions of various phones: http://forum.xda-developers.com/showthread.php?t=1959445. (It says it's for the El Grande but it has info for galaxy's, LG's etc).

You can re-partition the internal memory but not exactly like a PC. Some people do it to increase the size of the /data partition with space from /sdcard (internal memory.) For some devices you can use a simple linux utility like parted but for a samsung it's done by editing your pit file. Have a look at these 2 links.

I've never hardbricked a device, even after wiping my main partitions. It's just a general term for when your phone is so badly borked that it's completely unresponsive and you can't even access it by pc. Mostly by hardware failure.

Check out the above threads and just have a look around here yourself for others. If you want to post a new topic it might be better to ask in your device section to get advice that's more relevant to your phone.
Thanks for this answer, I'll read the topics you've posted and see what's there.
Thank you very much Art, I've (finally) read the topics you posted and now have a better understanding of Android partitions.
