[Q] Recover files from internal memory in recovery mode - Android Q&A, Help & Troubleshooting

Greetings,
I'm looking for help in the following scenario: some days ago I found that my Galaxy Note had rebooted, and got stuck at the Samsung logo. The phone has the stock rom, it is not rooted and is running Jellybean.
Recovering from this situation hasn't been possible. I tried:
- pulling the battery
- rebooting from recovery mode
- wiping cache partition.
I haven't tried a factory reset because the problem appeared as I was on vacation and there are some some photos I'd like to recover.
Taking this also as a learning experience, I have read several documents on recovery mode, adb, etc. So far I have managed to access via ADB. I could successfully run adb pull, however it seems not all data came through.
I don't have /mnt visible, no DCIM folder, and sdcard or sdcard1 have no contents. I've attached the screenshot of the Android Device Monitor.
For example, adb pull /sdcard returns 0 files.
I think maybe something is not properly mounted...? I tried to search similar issues it's not clear to me how to proceed. Anyway this is the output of 'mount' in case is helps:
[email protected]:/dev $ mount
mount
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
/dev/block/mmcblk0p9 /system ext4 rw,nodev,noatime,nodiratime,barrier=1,data=ordered 0 0
Thank you in advance for your help!

So after spending some time experimenting and reading about filesystems, ADB, sideloading, recovery mode (even went to a Samsung repair centre (they answered straight "no" regarding getting data from the internal memory)), I had to go with the factory reset.
So I answered 'yes' to all the warnings about losing all data, took a deep breath and waited...
Phone turns back on, usual out-of-the-box wizards etc, and then I start realising some options are the same as I had them... then I open the camera and notice a known picture in the gallery thumbnail... so, in a Christmas miracle, all my photos and personal files were NOT touched by the factory reset! It all lies inside /storage/sdcard0 and apparently this isn't touched by the reset.

[Q] Wrong Partition Type

I soft bricked my Vibrant after installing Bionix 1.4 w/Jacs OC/UV/Voodoo kernel. I used Odin to flash back to stock rom which was unsuccessful. It allowed me to boot to the samsung logo and then go black.
Grasping at straws I used clockwork recovery to do a nandroid restore to the vibrant9 rom I was running before (with the KingKlick kernel, but as I understand it nandroid doesnt backup or restore kernels). I thought maybe the kernel got switched back to the stock one but I'm lacking a ROM? Anyway, nandroid restored the system files but when going to restore data it gave me an error about not finding mmcblk0p2, when I go into adb shell and type mount, it tells me I have mmcblk0p3.
Is there any way for me to fix this so I can restore from my nandroid backups? I have everything in titanium and I can still access all the data on the sd card, but I'd really like to just have things back to how they were before installing the Bionix.
Thanks!
Here is a complete copy of what comes up when I hit mount if it helps. Could really use some assistance here, I try to do as much on my own as possible but I've hit a dead end.
Code:

Ok, thanks for all the help guys....
Anyway, for anyone who is having the same problem, I found my solution to be to get into download mode via instructions here: http://forum.xda-developers.com/showthread.php?t=741027&highlight=unbrick
And then follow the instructions in Fix 1 here: http://forum.xda-developers.com/showthread.php?t=782027
I had to upgrade to froyo then downgrade to get my file system back.
I'm now on stock Vibrant kernel and rom, but flashing Bionix 1.5 in a moment (NO VOODOO!!!)
Exact same thing
i had to do the exact same thing this morning. except mine would boot up fully. i couldnt get the internal memory to recognize at all so i couldnt disable the lagfix
blah blah blah... odin and fix 1 worked. i wished i had backups on my computer i should know better by now too. thats the stupid part. all that data lost.
Yea, I'm not new to this sort of thing, just this piece of hardware. I felt really confident after flashing a few ROM's and always read instructions for each new install, I was really surprised to find myself in that pickle. At least I learned something.
Going forward I'm being very dilligent about organizing a backup of my nandroid backups, different ROM's, everything needed to get back to stock, and most importantly the contents of my internal SD card! Nothing had ever messed with that partitioin before so I thought it would be fine, I also thought that nandroid or titanium would backup all my e-books since they were imported into Aldiko, WRONG-O!, it just saves the library index, gotta re-import over 600 books :O
Gotta love nothing ever being good enuf, now I'm off to fix what I broke on my car...

Recovery mode and SD Card mounting

Hi folks (this should be in the development forums, but I can't post there yet...)
I booted my Sony Tablet S into recovery mode, then managed to get the SD Card to mount. (Select option 2 and it will mount it up for you ). Using "adb pull" to retrieve /proc/mounts I get the following gem:
Code:
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
/dev/block/mmcblk0p4 /cache ext4 rw,nosuid,nodev,relatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk1p1 /sdcard vfat rw,nodev,noatime,nodiratime,fmask=0000,dmask=0000,allow_utime=0022,codepage=cp437,iocharset=iso8859-1,shortname=mixed,comp_uni,avoid_dlink,errors=remount-ro 0 0
From what I can see, this means if we can convince the system to run executables placed on the SD Card - we should be able to run a suid binary - and attain root (then be able to mount /system rw and add a su binary)
Does that help anyone?

Thank you. I hope it helps to mount sd for app2sd, psxperia, direct media playing soon
Sent from my R800i
How does the system decide if a program can run as root? The location it runs from?
Is there a cron function in the tablets, or ability to add something to the init.d steps?
An application which is both setuid and owned by root (known as setsuid) can be executed by any user and is granted root privileges immediately. That is how "su" (and other similar apps) work.
Unfortunately, i've discovered that the file system arguments it supplies are hardcoded - so whilst it can detect that a SD card is formatted with ext4 - the mount fails as ext4 doesn't support the FAT specific arguments.
So while we will be able to use this to get executables on the system - we can't get setsuid executables on the system, limiting us to executables being run as the "shell" user.
Yes. Ill help. I sent you a pm.
Ok, so whilst the SD Card method has unfortunately not panned out - I have found something potentially interesting none the less.
This lies in the update system used by Sony. I have determined that the updates appear to be encrypted using a Triple-DES key, which is embedded in, or retrieved by /system/lib/libautomagic_library.so.
This file has traces of apparently being written by HTC (the strings HTC_RIL, CDMA and PHONE all appear in it). It also has a reference to the location /data/data/com.sony.automagic.client.app/file/ (which doesn't exist on my device)
This library is used by the updater application itself - through a Java framework "automagic_downloader". Unfortunately, due to the use of the compiled C code for decryption and update verification (which includes SHA1/MD5 sum checks, likely against the previously downloaded info.xml, which it also handles) it is not possible to tell if the decrypted file is the one placed in /cache however.
The key "ro.sony.build.incremental" written in /system/build.prop is the version number used by Sony to determine if the system needs updating or not, as far as I can tell (with the C library being used, it is difficult to tell)
I have also noted, that when in recovery mode, the following two statements are present in /default.props
ro.build.description=nbx03_033-user 3.2.1 THMASU0035 0035.002 test-keys
ro.build.fingerprint=Sony/nbx03_002/nbx03:3.2.1/THMASU0035/0035.002:user/test-keys
I am not sure at this point if this just means that different keys will be used - or if the keys referenced are the ones available publicly in Android's repositories.
Please note that the above, whilst interesting, does not provide a direct path to rooting the device at this time. Note also that I was not able to complete the paths that the updater application takes codewise, so some of the code I examined may not be used - and thus the above may not apply.
However, if correct this may allow for the OTA images to be decrypted at some point, if someone can decompile those libraries (or otherwise extract the keys using a hex editor).

[Q] How to copy an entire folder with adb? "permission denied"

tl;dr
What I really would like is some way to move a file from my phone's internal storage (it's in /data/data/...) to my computer when it's connected via USB. I'll settle for a way to find my SD card directory and move it there. Alternatively, I'd be okay with putting it somewhere that survives a factory reset from recovery mode.
I'm bad with technology. I can only get my phone into recovery and/or download modes, and I want to pull a few files off it before I factory restore. I am on the default firmware (though my phone IS rooted) and I have no interest whatsoever in doing things like putting CWM on here. Thank you in advance for not suggesting anything of the sort!
I have adb installed. My computer "sees" my phone just fine. I can use adb shell and muck around, but I get "permission denied" when I try to look at anything other than the root directory or do anything. How do I change these permissions, or copy an entire folder despite them? I tried looking into it more and got "adbd cannot run as root" as an error, which I don't understand because my phone is rooted and Superuser is installed. Is it just because I can't turn the damn thing on?
I can get to the files (and see them) if I open ADB and use "su -" and remount the system as RW, which I figured out thanks to Google. I can see the file just fine, I just don't know the command to move it. Is it "cat"?
edit: it does seem to be "cat", for moving internally, but I can't move it anywhere that I can figure out how to access. I have an SD card in my phone, and /sdcard and /sdcard1 both seem to exist, but using cat to move a file to either of them won't make it actually show up on my SD card. Also, using ls on /sdcard doesn't display anything at all, so I don't see /sdcard/external_sd which google maybe suggested I should.
edit2: this is what "adb shell mount" returns. I don't think it's seeing my SD card at all:
C:\Users\User>adb shell mount
rootfs / rootfs rw 0 0
tmpfs /dev tmpfs rw,nosuid,relatime,mode=755 0 0
devpts /dev/pts devpts rw,relatime,mode=600 0 0
proc /proc proc rw,relatime 0 0
sysfs /sys sysfs rw,relatime 0 0
/dev/block/mmcblk0p9 /system ext4 rw,noatime,barrier=1,data=ordered 0 0
/dev/block/mmcblk0p10 /data ext4 rw,nodev,noatime,nodiratime,barrier=1,data=ordered 0 0
Click to expand...
Click to collapse
if I use "cd /mnt" and "ls" it doesn't return anything, so it doesn't see anything there.
edit3: I can also move the file with "dd". What a journey of discovery I'm having here! I just can't figure out how to move it somewhere that actually gets it off the phone. I tried exiting the shell (via Ctrl-D) and then using pull, but it just gave me permission denied again. I have it in /sdcard/ and I tried using "adb shell cat" and I created a file that has the only contents "permission denied"
I would also accept a way to just rip every single file, since I know the location of the thing I want, I just can't DO anything to it.
Thank you again in advance, I'm really bad with this stuff and I appreciate it.
Probably a total jerk move to bump this, but I've managed to narrow the topic down significantly, and maybe everyone will think there's a reply and flock in to read it and one of those people will be able to help me!

[Q] How best to use Android's internal partitions efficiently and leverage SD space?

I see various options for converting system apps <==> user apps and moving or linking some to SD. But I don't see a good general discussion of this. Also, I think my old phone needs a more hard core approach--probably one that trims down /system and reduces how much /system overlaps redundantly with updates on /data. So here goes...
First off, these solutions seem inadequate:
built-in apps2sd: it still fills up internal memory a lot.
s2e: an all-or-nothing approach for each category
free version of link2sd: cannot move-and-link app data, nor system apps
I've been fairly happy with link2sd, but it's still not radical enough for me. Can s2e be combined with it to reclaim even more space?
Assumptions about a stronger solution:
It will require root access.
It will break OTA (can this be turned off safely? can someone link to a good overview of problems/workarounds?)
It *might* require a fairly fast SD card (but still limited to an old phone's bus speeds, etc.) Note: I just bought a 32GB class 10 SDHC card (UHS-1 U3) for my s5360.
It might require one or two paid apps (hopefully not)
One of the most promising options I've seen is to convert system apps to user apps and then move-and-link them to SD. For the conversion step, do the following all do the same thing?
link2sd Plus (paid)
Titanium Backup Pro (paid)
System Tuner (paid) -- I've tried the free ones and move (and freeze) always fails.
app mover (free) http://forum.xda-developers.com/showthread.php?t=1999346
And are there rules of thumb for what can be safely converted?
EDIT: I just found this handy list--my guess is that any green or yellow Yes can be safely converted to a user app and even moved/linked to SD, but that red shouldn't, and think twice before uninstalling yellow :
http://wiki.cyanogenmod.org/w/Barebones#CM-10.1_App_list_.28WIP.29
Can apps that were moved to /data still be updated? I'd especially like to target outdated system apps that are have already been updated anyway and are thus running from /data anyway. My understanding is that 'moving' those to /data doesn't increase /data usage and doesn't reduce performance--just slightly reduces permissions--as long as I don't move/link them to SD.
lightningdude said:
In all seriousness, though, I'm not entirely sure the Link2SD has good implementation of this method. You might try Titanium Backup to convert system to user apps, then try linking it with Link2SD. It may still not work, but it'd be worth a shot, I suppose.
Furthermore, I always delete bloatware I'm not going to use with Titantium Backup. If I need to go back to stock for an OTA, I just flash the complete stock of whatever phone I'm on.
Click to expand...

If this can all be done successfully, can the internal partitions then be resized? That is, if we safely shunt some of /system and /cache off to SD, can we then let /data steal some space from both? (My s5360 has this by default: /system 230MB, /cache 40MB, /data 197MB)
My old s5360 seems to get full almost immediately after flashing a cm11 rom (LolliKat) and minimal gapps onto it, although I plan to try again with a version of minimal gapps that installs to SD.
For that matter, can some ROMs be installed primarily to SD? I get the impression that that's how some dual-boot (multiROM) approaches work, but I don't really know.
I've also seen one guide for permanently mounting /system as read-write. I think I'd be ok with that (are the security concerns truly awful?), especially if it meant that system apps would update themselves in-place without impacting /data. But I'm guessing it's not that simple.
can't create /system/... Read-only file system
I found another cool feature of link2sd to "integrate update into system", removing it from data and eliminating the double use of space. The free version includes this feature, but unfortunately it always errors out for me:
`sh: [51]: can't create /system/app/Music.apk.t: Read-only file system`
I tried upgrading to link2sd Plus, since that's the version that includes a convert feature, which requires write access to /system:

But that feature failed too, for the same reason. So I tried all of the following--granting each app superuser access for 10 minutes each time--and they also failed to successfully mount /system as RW:
X-plore - long press the / folder and choose System Shell, then enter `su` and `mount -o remount,rw /system /system`. It gives no error, but if I then immediately `cd system` and try to `mkdir xxzz` it gives an error: `can't create directory 'xxzz' : Read-only file system`. If I use the GUI, I can apparently create a folder under /system with no error, but if I browse up and come back, the folder is gone.
ES File Explorer (free version) - menu, Root Explorer, Mount R/W. I tried running it multiple times, setting both `/` and `/system` to RW. After doing this a couple times, `/` showed up as already RW, but `system` never did. I immediately retried link2sd Integrate--fails with same error.
mountsystemrorw - this app is dedicated to this one task, and when I click "MOUNT /system RW" it claims success ("Your system is now mounted RW!"); but it actually fails. (At least, link2sd Integrate and X-plore still give the same error/failures.)
AnExplorer - menu, Root. I don't see 'mount' options.
Has KitKat made it nearly impossible to mess with /system, even as root? Or am I doing something wrong?
Just in case, I tried re-running "recreate mount scripts" in link2sd, which had worked before, and this time it failed too! `can't create /system/etc/init.d/11link2sd: Read-only file system`. So maybe something has changed since I first installed link2sd. Hmm. I do see this in a thread on stack exchange, "Write access to the system partition is usually blocked by the kernel at boot." But "recreate mount scripts" worked before, *after* I'd flashed the current kernel (Kernel Bangprovn#1.zip) and ROM (LolliKat Stable 2.zip). That's how I got the ext4 partition working for link2sd in the first place.
I'm getting frustrated and don't want to have a big fight every time I want to integrate or convert an app. So I'm wondering just how feasible the following might be...
I've also seen one guide for permanently mounting /system as read-write. I think I'd be ok with that (are the security concerns truly awful?), especially if it meant that system apps would update themselves in-place without impacting /data.

I'm guessing they wouldn't simply self-update. But if I could easily run the Integrate step without this RW battle, that might be enough.

using bin/mount rather than xbin/mount
I finally found a solution: remount by explicitly using `/system/bin/mount -o ...` rather than just `mount -o ...`. I'm guessing that at some point the version in /system/xbin started taking priority and for some reason that version fails silently. More info here:

YP G70 read only??

Hi all
I have in my hands a Samsung YP G70 with this problem: I need to format it, clean it COMPLETELY.
I tried the following things:
1-Using the stock recovery, clean data and cache
2-Flash via Odin (different processes): his original firmware (same version), another firmware, a Kernel that should included the CWM Recovery
3-Root with Kingo
4-Tried to flash the TWRP flashable version into his stock recovery
5-Restore at factory default from the player
No one worked
After the reboot I will always have the same data (same accounts, same photos, same apps)
If I add a file, after a reboot, the file disappear; if I delete a file, after a reboot, the file re-appear.
So: how can I completely clean it? Or should I trash cause the memory allocator gone crazy?
Thanks a lot

5-Restore at factory default from the player
No one worked
After the reboot I will always have the same data (same accounts, same photos, same apps)
If I add a file, after a reboot, the file disappear; if I delete a file, after a reboot, the file re-appear.
So: how can I completely clean it? Or should I trash cause the memory allocator gone crazy?
Thanks a lot

Please post the output of "mount" after a normal boot ( not in recovery )
You can do this in adb by doing:
adb shell
su
mount
or in a terminal app
su
mount
Then copy the output here or a screenshot with the info is fine...
$ su
su: not found
$ mount

So even if you flash a kernel it does not change?
Nope... Tried but not works... Same kernel after the reboot from Odin
