/sdcard suddenly appears as a file - Android Q&A, Help & Troubleshooting

I just had something a bit disturbing happen and I am hoping someone can help me out real quick. I just plugged my phone into the computer, pushed a file to the sdcard and then unplugged it. When I opened Root Explorer, it didn't default to my sdcard as usual so I opened the built in file manager and it found the card just fine. I checked the /mnt folder and sure enough the sdcard appears in there. /sdcard has always shown in my root directory and has done so up until now. Now, instead of a /sdcard folder, I see a file in the root directory named sdcard. I fear the location change could cause issues (the least of which is tweaking out my OCD). Can anyone tell me why this happened or what to do to fix it?
Further details:
I didn't do anything out of the ordinary. USB Debugging is enabled, I left the phone in charge only mode, I ran the command "adb push C:\directory\file /sdcard" and it appeared to be successful, I unplugged it without using the "eject" function on the computer. I've done this many many times before and this has never happened to me. I have a Droid X and am running Wizard0f0's MIUI build. Again, none of my steps vary from what I've done before. The computer is the same, the drivers are the same, the location of adb is the same, etc.

Disregard this... I shutdown my phone, pulled the card, started it up, shut back down, put the card back in and started it again: everything is fine now. Not sure whether pulling the card or simply rebooting was the fix.

[Q] Bricked and Malfunctioning Partitions

I have a GTab that was running Calkulin + Clemsyn Combo Overclock at 1.5 ghz V8 on the 1.2 branch fine for a couple months now, then something happened today. Woke up to find there was no sound coming from it (I'd left an Anti-mosquito app running all night), so I tried to play a couple music files. Seemed to get frozen instead of playing, so I restarted. That's when it went into a boot loop from 3 birds to the first splash screen of the loaded ROM.
Attempted to do a backup via CWM, and it failed on /data. Tried a data wipe/reset, then reflashing the ROM and finally NVFlash. Still goes into a bootloop. Repartitioning and mounting doesn't do anything; ADB doesn't see the device at all in CWM or APX; /data cannot be mounted and /sdcard mounts only when a card is inserted (doesn't see the internal space) but still doesn't mount USB storage and says: "E:Unable to write to ums lunfile (No such file or directory)"; drive shows in Win7, but is inaccessible;
As mentioned, APX mode and NVFlash along with CWM works fine. And I can mount /cache and /system fine. I've gotten to Code Double Red here and now I'm draining the battery for the next step (really don't want to pull any screws). Also tried the fix here, but it seems that's just for CM7, which I'll probably try flashing some time.
I'm going to return to the 1.1 branch and try a couple ROMs there, but I have a really slow connection and it's taking a while to get nvflash 1.1.
Did a quick search of the forum and didn't find anything quite similar. Obvious question is, has anyone ever experienced this before? What are some other steps I can take to fix this? Is there a way to backup the internal SD before I probably have to wipe it?
Connect the USB cable to the tablet, then boot it into CWM, and run this command on your PC:
Code:
C:\SOME\PATH> [B]adb shell dmesg > dmesg.txt[/B]
Post that dmesg.txt file here. We'll see what's wrong.
Connected the charger long enough to run the command, but all I get is "error: device not found". As I'd said, ADB doesn't detect the tablet, even though Windows knows when it's connected and disconnected. Is there anything that I can flash to get me a terminal? That's the only way I can think of to get that command run and hopefully direct the output to my SD. Thanks.
I now have a completely dead battery. Wondering what to do next since it's supposed to have been hard reset now. Not seeing anything different after booting; same boot loop even though I just flashed a ROM again.

I had seen this thread before where you were helping someone last year. Wish I'd read further to see that he eventually got the same problem I now have. I'm currently working my way through everything. First I need to get ADB running though, so I'm working on that now. Think I may be needing that partition swap trick, but we'll see...
Having issues getting the right USB drivers installed for ADB on Windows 7 64 bit. Using instructions here. But each time I uninstall the device, as soon as I plug in the tablet, it installs the default drivers. Using both Device manager and USBDeview. Updating and other options are also disabled when there is nothing installed. Considering to do a direct registry hack of the device info if I can, and hopefully not break anything important.
Try using Linux.
I finally got ADB working on my system and did some experimenting. Seems there's definitely something wrong with my internal SD according to the dmesg output. Luckily I have a SD which I used in my SG3, and it is already properly partitioned, so I'll try using that. Tried making a fstab file in /etc (mtdblock3) but I got "Magic Value Mismatch" error, so I NVFlashed to return it to how it was. I'm currently researching how to create update files, because it seems that's the only way I can get the SDs swapped. Any guidance is still welcomed. Thanks alot.

Yeah. There are clear error messages relating to the internal SD card. You can either return the tablet and get a replacement, or, use my SD card device swapping technique to use the external SD in place of the non-working internal one.

If you use my files, you don't need to modify anything manually. What're you trying to change, BTW?
I can definitely use some help there. Where are the files? I tried modifying the custom ROM I use by adding a custom fstab and vold.fstab to /etc, an init script to init.d and replacing the /data mounting command with:
Code:
ui_print("Copying Data Files");
run_program("/sbin/mount", "-t", "ext3", "/dev/block/mmcblk2p2", "/data");
ui_print("Mount information:");
ui_print(run_program("/sbin/mount"));
Not sure what you're attempting to do here...
If you just want to use an external SD card in place of your non-working internal one, then all you have to do is a) flash either one of the CWM zip files and then b) flash the SD card swapping zip file right after you install the ROM of your choice. And, if you tell me which ROM you plan to install, I can look inside it and tell you if my scripts will work with that ROM.
If you can read shell/awk scripts, you can look inside the zip files to see what they do and how they do it.

I was trying to make a swap script myself, but it's not working. /system dir gets corrupted. I'm using Clemsyn_Caulkinver8final2, a Froyo ROM.
Look at my scripts. If you have any questions, just ask.
Where are the scripts? That's what I've been asking...
EDIT: If this is what you use, then all should be ok. Let you know the result when I'm again online. Thanks alot for your help!
That's what I was talking about. I modified the device-swapping script today to fix-up an additional shell script, /system/etc/inandop.sh, on the various Clemsyn/Beasty ROMs (incl. yours), so use the newer zip file.

Appears it still doesn't work. However, now instead of having a boot loop, it's just stuck at the splash screen after the 3 birds. I'm going to try combining your script and the ROM to see if I can get better results. I'm also going to try inserting some log/debug messages where I can.

THANK YOU RAJEEV!!!!!!!
Today I got the time to work on my tablet again, since I just restarted college and it's been a bit hectic. Decided to try CM7 since when I looked into your script I saw direct management for it, so I NV'd back to 1.1 (I didn't know what branch CM7 was on, but flashing CM7 on 1.2 gave an error and aborted). The first time I tried the CM7, it got to the CM7 logo, then was there for a while until I only had a black screen. The only way I knew the tablet was still on was because ADB was still connected. Then I flashed your script and VOILA! everything started great. So now I have my tablet again for my classes .
I am planning to still run a few tests to see if I can somehow recover/fix the internal SD, so I downloaded your set of e2fsprogs. Think I'll make a flashable file for the entire package.
Again, thanks for all your assistance. It's much appreciated. I really didn't have that much time anymore to work on it myself too. I will continue to learn more as time goes on though, and I hope one day I'll become a guru like you .

The official CM7 is, right now, only for 1.1. However, since you can replace just the kernel and instantly make a 1.2 ROM, you'll have to look at the kernel messages to tell which bootloader version you have (Note: this is only for pershoot kernels).

This is to be expected. When a ROM first runs, it writes a whole bunch of stuff into /data; but, your internal SD card is messed up, so every write would've ended up with the kernel retrying for quite a bit and then failing.
You should've flashed the ROM and immediately afterwards my script to fix-up the mount points on the ROM--ie. before the first boot.

I doubt if you can "fix" your internal SD card error using any of the e2fsprogs--it looks like a card-controller error rather than a media error. You have one of the non-standard internal SD cards which has caused problems for some other users as well.
Ok. I do have a few issues I hope I can get some help on. For one, flash player doesn't work, and that's something very important. All my browsers direct me to get flashplayer. It worked pretty well in my previous ROM, so it may be an issue with CM7, but I haven't seen any similar issues on their site.
Also, the tablet is less responsive now, though I think this has to do with the /data partition being on external SD, though it's a class 6 card.

Did you partition the external SD card correctly into 2 partitions (the first as VFAT and the second as ext3) before you installed CM7? I'm not sure what steps from my post you followed and what steps you skipped: you mentioned you were planning to modify the scripts/ROM, right?
It is also possible that my script is not doing the right thing on CM7 since it doesn't touch the vold.fstab on it. Get me the output of a mount command in CM7, and these files:
Code:
/system/etc/vold.fstab
/system/build.prop
Also make sure that you, or the ROM provider, haven't enabled the SD card switching in Settings > Cyanogenmod settings.
The SD I'm using was in a SG3 using this ROM, so I think it's correctly partitioned. I've accessed the partitions before and the correct names are associated with the contents. I only followed steps 1 & 4. The option to use removable for apps and media is disabled.
build.prop
mount.txt

[issue] all files on sdcard disappeared

i tried to copy some music but it blocked, i tried several times but same issue. then i unplugged the phone and replugged it. i could still see all files but not access anything. i just reboot the phone and there all files on the sdcard had disappeared !
i plugged again on the pc, i could see a few files that i don't see on the phone with a root browser. i unplugged and plugged back and there no files anymore even on the pc (of course on my options i can see hidden or system files).
Strange enough when i check partition size on the pc it says i have over 500Mo used and when i look on sdmaid (android app) it tells me that mnt/sdcard is 543Mo size. but me i can't see any files. Apps using the sdcard (like evernote) had to recreate a new folder on the sdcard and i lost my datas. if i check folder by folder it tells me only 2.6Mo used... (LOST folder being empty)
i guess it is possible to recover all as i can see the used space but i don't know how.
i tried recuva or testdisk but it does not detect this kind of partitions
i searched on xda/sonyforums/google but did not find anything relevant
does anyone know about this issue ?

I had this problem and had to reflash a stock rom. That fixed it but I lost everything on the card. Not a big deal though since I had backed stuff up. Seems like it may get corrupted somehow.
i tired some recovery softwares, it did not really work (hexamobile found a lot a of things but not the ones i needed and undelete found almost nothing) but i noticed with "undelete" that it proposed me 2 "mnt/sdcard" path with different results, so i guess the problem is here ! Also when i plug to my computer i don't see the folders created today, only the ones created yesterday :/
thanks for the feedback Mr Satan, i chek a bit if i find a better solution but if not i will have to do like you did

[Q] Vibrant Slim Bean Issues

Recently I decided to try Slim Bean on my phone, seeing they released a new version a few days ago. I had been running Cyanogenmod 7 but decided it was time for a change. Initially, everything worked great, I was able to reinstall all my old apps, send texts, and things functioned well.
About 12-14 hours after doing this however, my phone stopped having signal. I didn't reboot it or anything, just no longer would it pick up a signal. Checking the about phone revealed it saying it had an unknown baseband and IMEI, I wasn't too concerned, I had backups of the EFS files, so I turned on USB debugging, plugged my computer in, and used an adb shell to move the backup to the main system. However, this still didn't work for my phone.
According to the Slimrom's FAQ, there are two solutions to this: delete the 00check and 98tweaks files in the system/etc/init.d folder, or just reinstall the ROM. However, using an adb shell or a terminal emulator on my phone, both with superuser powers, I can't remove those files. chmod spits back that they are read-only files. lsattr shows only the A tag active, which shouldn't be standing in my way. I seem powerless to get rid of these, and I can't find any guide as to how to do so. I've tried restoring to factory defaults and reinstalling the ROM, and this time I don't have signal right from the start. Can anyone help me figure out what to do about this? I've searched around and can't find any answers, which is making me think I'm just missing something really stupid. Any help would be appreciated!
Update: Figured it out. The system partition was mounted as read-only, and I thought I had tried remounting it but must have tried a higher level directory or botched the command. mount -o remount,rw /system gave me the ability to delete those files. Sorry for the trouble!

[Q] I think I killed it.

Alright, so this is going to take a bit of explaining, please bear with me.
I got this phone a couple of weeks ago, subsequently rooted it, and shortly thereafter decided upon Viper for my ROM. After playing around for a bit, I took a look at Beastmode kernel yesterday. I backed up my phone, installed the new kernel, and everything went to hell shortly thereafter. Upon rebooting, my phone no longer detected a mounted SD card. Along with this, it also doesn't have working audio. I tried rolling back to my restoration point, but I cannot find it now. While digging through directories in recovery, I've found two things out.
1: There is now a storage/emulation/legacy folder with (almost) every folder that was in mnt/sdcard.
2: My restore point is gone, and I don't have the original kernel on my phone
I figured this wouldn't be THAT big of a problem, connect my phone to my PC, go into ADB and try to push the stock s-off kernel. Next set of problems.
1: /mnt/sdcard is showing as a non-directory, insists it doesn't exist.
2: storage/emulation/ shows as read only, and all lower subdirectories are coming up as not existing (I believe it to be an issue with folder naming, legacy is actually 0 on my file explorer on the phone, I think?).
Where I stand now::
At this moment, I have the HTC Droid DNA Toolkit running, the stock s-off Kernel, and a phone that doesn't cooperate with anything.
Also; I tried downloading the .zip directly on my phone, but because it doesn't think there's an SD card, it's refusing to let me download it. It lets me download apps from the market, though.
Any ideas?
PS! Forgot the biggest SNAFU in all of this. On my phone are about 200 pictures from my vacation which I hadn't put onto my computer yet because I am an imbecile. This is keeping me from wiping the phone down to brass tacks and starting all over. If someone can find a way for me to pull said pictures from my device, I can wipe it and see if that helps.

Have you tried using an OTG cable to mount a flash drive? That's what I do when I backup/flash anything, I keep all my roms, kernels, backups, basically anything flashable on a flash drive, and use an OTG cable in CWM.
For the pictures:
Step 1; adb reboot recovery
Step 2; adb devices (to make sure it's detected)
Step 2.1: If your phone isn't detected, open sideload in recovery, adb devices again, then close sideload
Step 3: adb pull /sdcard/ C:\<username>\Desktop\sdcardbackup\
To fix everything else you'll probably need to wipe everything and flash a new rom.
EDIT: For future "snafus" the sdcard is on /sdcard/ not /mnt/sdcard/ because it's on internal memory, not mounted memory.

Well, I feel silly for that confusion. I've pulled everything from the sdcard, which honestly mattered more to me than fixing the phone. I'll putter around with getting the ROM and kernel operating correctly in the next couple of hours.
UPDATE!
Once I had the adb pull command corrected for me, pushing the new ZIP on there was an instant success in recovery. SD card exists correctly once again, installed Viper ROM over, full functionality once more.

you can always do this too as long as the device is recognized by adb
Code:
adb shell
this will get you into the actual device where you can navigate around by using the " cd /dir_name " command and to go back up a dir use " cd .. " (a space and 2 "."s are needed) or just " cd " to get back to the starting point... if you know how to navigate through a unix terminal then you will know what to do here...
some other useful commands
Code:
ls, ls -a, ls -l, cd, cp, mv
ls = list (lists files/folders) "-a" means all, "-l" just makes it look neat and laid out better.
cd = change directory aka "dir"
cp = copy /path/to/file.ext /path/to/where/you/want/to/save/it/file.ext
mv = move (same as ^ ) except it just moves it and doesn't copy
oh and to exit adb shell just type "exit"
Honestly, just grab a working kernel. And use fastboot. Especially since you're s-off
fastboot flash boot boot.img should get you back in working order.

Unable to mount internal storage after flash? Here's how to fix it

You have never seen me here, though I have been lurking for quite a while. I don't know that much about how Android works and usually leave everything up the pros. Recently, as in 1 1/2 hours ago, I tried to flash CM 11 through 4EXT. Well... it failed. I was stuck at the HTC loading screen and couldn't access the internal storage. I dug around the internet for a while and, while I did find some work arounds to fix it, they were lengthy and didn't work on Windows 8.1. So, being the impulsive person I am, I attempted something extremely stupid to hopefully solve my issue... and it worked! So, here goes:
1) Boot in 4EXT (not sure if it works on other recoveries)
2) Press the USB storage button
3) On your computer, open up explorer and find where the device is connected (there should be two partitions, D: and E:\)
4) One of the two will have files while the other one just shows a device (for me, it was E:\). Right click, hit properties, then format it. Yes, your read that right: Format it.
5) Reboot your phone into recovery. You should now have access to the internal SD card.
Nice helpful first post. Next time I get stuck like that I'll have to try. It beats the heck out of reinstalling.
