Help with format

I have flashed a few of the different builds that have recently become available and in doing so I have had some weird happenings with my internal storage. First I had both /sdcard, and /sdcard/o where everything I had prior to flashing was in /sdcard, but now resides in /sdcard/0. I moved everything back over and all was dandy. However now I have /sdcard and in there is nothing. All my stuff is actually in mnt/shell/emulated??
I know that chadouming and the everyone else that are contributing are working hard to get a stable build of CM10.1 out to everyone, and when that happens I want to start fresh.
Now my question is how do you go about formatting your internal sdcard without screwing everything up?? Should I flash ROM, GAPPS, backup's from Nova, and Titanium then format? I just don't want to be left with a phone that won't boot for whatever reason.
typically in the past I have never done this. But contrary to some of the instructions for flashing ROMs in this forum I used too
Wipe system/factory reset
Wipe Cache
Wipe Dalvik Cache
format system, data
then flash rom then flash gapps. There is a lot I still don't understand about this stuff so any help would be appreciated.

Ah, you didnt said that. You can't simply delete the 0 folder on sdcard. That's how thing work on android 4.2 and it's because of multi-user capabilities. put everything back in 0 folder nad it shoulbe alright. Note that it's zero and not "o"

I can't move things. I am able to select files, but it won't move them. Tried with CM file explorer and with root explorer. Won't work with either. Wouldn't be a problem if I could access them from my computer, but I can only see /sdcard when it comes up, so I can't access mnt/shell/emulated. Frustrating.

I have downloaded a program called android commander to access internal storage on my phone via pc but I can't get it to work. I can't for the life of me even get the drivers for the phone to install correctly. Grrrr. Don't want to lose this data but I cannot seem to gain access our move it.

Yes this is my problem. I can only access the /sdcard portion of the internal memory through my pc. The 0 folder along with the original /sdcard folder is now located in the above mentioned directory /mnt/shell/emulated. It's very strange, and what is more frustrating ifs that I can select the files to move them through root explorer, but when I hit paste nothing happens.

That would be fine but I can't access that directory on my pc. Hence the problem.

[Q] Storage space issues after updating from CM 10 to 10.1 M2

I just updated from cyanogenmod 10 (stable) to 10.1 M2 using goomanager to flash the rom and the 20130301 gapps (didn't set it to make backup or wipe anything). Phone seems to be running everything fine but my storage space is wrong. It shows 2.17 available, 2.20 for Apps, 2.23 for picture and video an negligible everything else. Total space 13.33. Using an app called "Storage Analyser" I can see that in /data/media I have 9.3GB and it has all the old info in it from CM10 as well as the new info in the new "0" folder (which will include the 2.2GB picture and video data above) and 4.85GB in a folder called ".dumpster".
So, I guess the questions are:
did I do something wrong when updating the app that it kept all this old information? When I updated from stock to CM10 it put all the old info into a folder called "0" I think, but I could see that in normal file explorers/windows and delete it easily. Not the case here - I had to go into root mode etc to see the files.
can I / should I be deleting every folder in data/media except for the "0" folder? If not, what should I be doing?
Appreciate any help. Would like to avoid messing my phone up by deleting things I shouldn't and also don't want to have to full wipe and reinstall CM10.1 just to get arround this issue

/data/media should have three folders in it once you're on Android 4.2: 0, legacy, and obb. The "0" folder is what, after fuse mounts and symlinks, ends up as /sdcard and read by Windows via MTP. That's why you couldn't see the other files in /data/media on Windows.
If all of your data is in /data/media/0, then anything other than the three folders listed above can be deleted from /data/media. If you're unsure, don't hesitate to transfer the files to your PC as a failsafe backup (zip, move to /data/media/0, and copy it off via MTP; adb pull it; etc) before deleting.

Accidentally formatted '/System' in CWM

So I'm not panicking as I know this is most likely recoverable, but I do want to make sure I do this right. I was prepping my galaxy nexus to give to my wife since I got a note 2 and was consequently trying to get it completely wiped. I was trying to clear all the user data and was surprised that it was clearing (I think it was because it's is stored in the /sdcard directory). So, I popped into the mounts and storage section and started formatting . Seriously, I'm not sure what I was thinking here. I only got to the /sdcard and /system before I stopped and reconsidered, but it was too late. Because I had already formatted the /sdcard, I lost my rom and gapps zips.
Anyway, I think all I need to do is hop into adb, transfer the necessary zips to my /sdcard directory, and flash them. Is that correct? Also, of the options on there, what can I format without issue? /system is obviously for the rom itself (or at least mostly), so I'll avoid that in the future. What is the /data and /cache used for?

Yes you are correct about your process. I even there myself about five times now not knowing what I was thinking when I pressed all those buttons hah.
Data is used by android for app caches and the cache is for system and kernel caches. May not be entirely correct but they are safe to clear

I actually was trying to format everything to get the GN as clean as possible and ended up deleting everything including my rom that I was going to install(CM10.1). Thankfully recovery was still on there and I just pushed my rom and gapps using adb. I couldn't get the sideload command to work using clockwork so ended up just using the push commands. Make sure to specify the destination folder on your phone with the file name it will be on your phone. I ran around in circles realizing I wasn't specifying the file name in the folder location. Good luck!

[Q] gt18160- adb pull sdcard file permission problem!

Hello lovely android people,
I am a newbie, so im guessing this probably isnt the right place to post this type of question. Please feel free to guide me to the right place.
So the question...
I rooted my galaxy ace2 (gt18160) and install Pimp My Rom app from the market. Did some changes with it and now the phone wont start up, stuck in the bootloop where the logo appears and it does not go anywhere from there.
Ive been researching for solution since yesterday, and found out that I could re-flash the firmware using o2 stock using odin.(although im not quite sure this is a correct solution)
Since there's a possibility of all the data getting deleted, I want to get some files out of the device using ADB pull.
I used adb shell to look for the files I need. At first I could see the sdcard in the root directory / but could not access it without su. After doing su command I can go inside the sdcard directory (where my files are), but it appears to be empty.
ls -l /mnt lists the sdcard with unusual d--------- permission.
Im stuck and dont know how I can grab my files from the sdcard folder.
any suggestion will help.:cyclops:
Thanks

mnt/sdcard is only a symlink to storage/sdcard0 (mount for the internal sdcard) so it does make sense that adb can't cope with that path.
Still, it is impossibibble to delete stuff from either of your sdcards via odin or recovery. Flashing via odin doesn't wipe the data partition either, so as ong as u select the right firmware for our phones, nothing can go wrong really

Thanks for your reply Carpe-Dimi.
after checking /prop.partiitons, it seems that sdcard hasnt been mounted.
The problem now is that there are 18 partitions and I dont know which is the sdcard?
I tried mounting the first mmcblk0. Give me the 'device or resource busy' error.
Excuse my arrogance but I would have liked to find out why I cant access the sdcard or why I cant mount the partitions.
...and thanks again for letting me know that flashing does not wipe the data. :good:

SOLVED!
As Dimi said, flashing does not wipe data partition. But I was able to recover my files in recovery mode as it automatically mounted the mmcblk0p8 partition.
Then installed stock firmware.... tried new jelly bean, then went back to stock as its slow and laggy.
Cheers

[Q] Strange file directory structure

I’m rooted and using CW for my recovery. I’m using a pre-owned phone that I (thought) I wiped before rooting. I am running stock 4.2.2, baseband MDL.
Initially all I wanted to do was nandroid to my SD card in preparation for flashing a custom ROM. I have a 32GB card that my phone recognizes just fine, so I thought it would make sense to put the backup there. So I enabled Use External Storage in ROM Manager settings and tried to begin the backup process.
First I tried it using the ROM Manager itself. Got this error message:
Unknown volume for path [/external_sd/clockworkmod/backup/name of the backupfile here]
/tmp/recovery.log was copied to /sdcard/clockworkmod/recovery.log
Please open ROM Manager to report the issue​
Then I tried doing it by going straight into Recovery and initiating it myself. That was in the Backup and Restore menu. The Backup location options were
/sdcard
/storage/sdcard1
Neither of those is the external card. Then I looked at the Advanced menu but there was no option that mentioned the external card. So it seems that the Recovery doesn’t see my external card. And the subdirectory options that Recovery wants to use do not exist on my phone.
At first I thought it was my SD card. I removed it, re-formatted it (non-Quick) on my computer, etc. I was still not able to save my recovery to my SD card. Again I see that CW want to put the recovery in a subdirectory that does not exist.
I was able to nandroid to the internal memory, so at least there’s that. But the file directories on my card are a mess that make no sense and don’t seem to match what I’ve seen on multiple forums.
Using ES File Explorer I see this from the root directory -
/storage/emulated/0
/storage/emulated/legacy
/storage/extSdCard
/storage/sdcard0 – this one has a little arrow at the start of the pathname. Does that make it a shortcut?
/storage/container – this one has a little arrow at the start of the pathname. Does that make it a shortcut?
Also from the root directory I see this –
/sdcard/ – this one has a little arrow at the start of the pathname
Then there are these –
/mnt which seems to have copies of sdcard and extSdCard
/mnt_1 which just has extSdCard, sdcard_1, sdcard_2, and sdcard_3
I’m running 4.2.2, baseband MDL. What I would like to do is get the directory structure back to stock and remove all the multiples of data and folders that I am seeing.
1. If I totally wipe the phone, will the stock file structure be restored?
2. If the answer to #1 is “yes”, what happens if I do an Advanced Restore, restoring Data from a nandroid created with the screwy structure? Does the screwy structure return?
Thanks,
Veronica

If you wipe the phone using it's internal "factory data reset"
(settings>accounts>backup and reset>factory data reset)
It will restore the stock phone's internal sdcard's structures, directories and folders.
But what I would suggest is to download and odin flash the TWRP custom recovery,
that way you will not loose any data or user files and you will not have any problems
making or restoring nandroid backups.
TWRP is really easy to use and basically self-explanatory.
Here is the direct download link for TWRP: http://techerrata.com/get/twrp2/jfltetmo/openrecovery-twrp-2.6.3.1-jfltetmo.tar
Good luck!

Are you saying that using TWRP will preserve the file structures and that CW has some kind of effect on them...or that CW is the reason I can't put my backup on my SD card?

CWM or TWRP do not effect the file structures.
All I am saying is create a nandroid backup using TWRP and then restore
the backup. Then if it works properly for you then keep using twrp.
You will be pleasantly surprised how well twrp works and how easy it is to use.
Good luck!
