[Completed] [Q] How To Fix vold.fstab in Maxx GenxDroid7 - XDA Assist

I have Samsung Maxx GenxDroid7, which has very low internal memory (<200 MB). I have an external micro SD card of 16 GB, but still couldn't install many apps due to insufficient internal memory.
I read on the Internet that if I modify vold.fstab and replace the word "sdcard" with "sdcard2" then my external SD card will act as internal memory.
So I rooted my phone and installed Superuser, but I haven't installed ClockworkMod recovery or any other custom ROM yet.
Problem Description:
I installed ES File explorer on my SD card and allowed root access to it via Superuser. I then went to /system/etc/ from ES file explorer, edited vold.fstab and replaced the word sdcard with sdcard2.
When I restarted my phone the external SD was no longer accessible. ES File Explorer is also gone, so I cannot undo the change that i did. I tried installing ES again from my data connection, but the installation fails (and the phone reboots immediately). I am not able to install any new apps.
I am unable to access my external SD card, so I can't put anything there via PC or via recovery. I tried pressing the power button +Volume down to go into system recovery mode. I see only these options
reboot system now
apply sdcard:update.zip
wipe data/factory reset
wipe cache partition
When I try to select the second option, it says "installation aborted" as the SD card is not accessible. I tried to select the 3rd and 4th options, but that didn't help either - I think factory reset will not reset vold.fstab.
I only have the default apps and Superuser now. I somehow need to find a way to get write permission to /system/etc or to /system/etc/vold.fstab.
Can someone let me know how I can edit this file again? I don't have an original vold.fstab

Hi
Thanks for writing to us at XDA Assist. Have you tried formatting the sd card back to its original state?

Not Work

I think the best idea is to ask the person that wrote the guide you followed in the first place how to reverse what you did.

Clockworkmod 4.0.1.5 can't create backup on SD card

I tried to do a search on this but found nothing, and I'm also apologizing ahead of time if I'm posting in the wrong section.
I am trying to get my LG G2x to a stock ROM using this guide: (can't post link since it's my first post, but it's "how to unroot the tmobile g2x" at the unlocker.
I was able to follow the steps and installed clockworkmod on the phone (v4.0.1.5). I am however having problem on step 6. When I do the the backup on clockworkmod (CWM), it automatically is doing the backup on the phone's internal memory, and not the sd card.
I tried to mount the phone with the PC and cut and paste the folder to the SD card, thinking CWM would pick it up after a reboot of the phone. However, this is not the case. I tried to find the SD card by trying to do "install zip from SDcard" in CWM, but there is only a DCIM folder in the _ExternalSD folder, and nothing else. No matter what I do, the backup is always saving to the internal memory, and not the SD card. If I leave the backup on the phone's memory, it is showing up under recovery in CWM, but I'm guessing it's not possible to flash the phone while it's running from the internal memory.
I formatted the card at least 3 times, and even tried another card just to be sure, but no luck still.
Am I doing something wrong? Do I have to do something to mount the card or unmount the phone memory? If anyone could please help. I have to send in my phone for warranty in a few days, and I desperately need to get it back to stock. Thanks.
Nvflash latest recovery (5.0.2.7 i believe)

Worked like a charm. I guess I had flashed the internal and SD option for nvflash, and that's what was messing up. 5.0.2.7 allows you to save only to SD card, so it worked perfectly. Thank you so much!

Latest also allows you to flash from internal/external.

[Q] Unable to mount SD card

Ever since I first got this phone, I have been unable to detect/mount the SD card in CWM, and under "Storage" in "Settings."
Oddly, I have no issues accessing "sdcard" in the My Files folder, or in Root Explorer.
Whenever I flash a ROM, I have to select "choose zip from internal" instead of "choose zip from sd card."
I have no issues with doing this, however the reason I think that I should fix this is because I keep having problems with Market FC's and "phone is not compatible" error messages when trying to get apps from the market. Also, I am unable to use Nandroid in CWM because of this.
I have followed the instructions here except I obviously was unable to format the SD card.
Thanks for any help!
I got help in another thread and fixed my Market compatibility problems.

Thanks to Schwaxdoc for that.
So no more issues with the market anymore. I'm still interested seeing if there's anything I can do about my sd card not mounting.
I've had the same issue, ROM Manager tells me that the SD card needs to be mounted when it already shows as mounted in settings OR it says "unavailable" in the space for both internal and external.
I can fix it by removing the SD card, turning off the phone, inserting the SD card, and turning the phone back on.
It almost always reoccurs every time I flash a new ROM.
I'm having the same problem, and I've tried to use seanscreamz fix in the link you posted but that didn't work (but, like you said, since I can't mount the sd card I can't format it ).
Does anyone have another solution? Even after going back to stock, wiping data, cache, system etc. nothing seems to work. I can't use ROM Manager, can't restore nandroid backups, can't mount the damn sd card!
I've attached a picture of the Storage display if it helps (USB Storage appears to be my sd card and the sd card is 0 out of 0).
Woo hooo!!! Fixed it. I can now run Nandroid backups and presumably restore them.
I'm not sure what worked, but I think it was flashing the latest CWM from ROM Manager. The Odin-flashable cwm I had didn't have the options for "Backup to Internal SD Card", "Advanced Restore", etc.
Other things that may have helped:
--Tried seanzscreams repair here: http://forum.xda-developers.com/showpost.php?p=21424179&postcount=1 (but obviously couldn't format the SD Card that I couldn't mount).
--Flashed back to stock, wiped data/cache in 3e recovery.
--Rooted, then clean install of Alien 5.5 rom using DARKSIDE SUPER WIPE first (new! found here: http://forum.xda-developers.com/showthread.php?t=1487706)
But I'm pretty sure that flashing the latest CWM from ROM Manager was what fixed it.

[Q] In ClockwordMod Recovery but no Cyanogen Mod update zip

Galaxy S2 GTi9100
Hi,
I rooted my phone today and am now trying to install Cyanogen Mod. I followed all steps on their Wiki but now am facing a problem.
- The wiki says "Place the CyanogenMod update.zip file on the root of the SD card. "
- I placed the update .zip file on the root of the external sd card. Seems like that was not what was intended.
- I followed these steps successfully:
Boot into the ClockworkMod Recovery.
Once the device boots into the ClockworkMod Recovery, use the side volume buttons to move around, and either the power button or the trackball to select.
Optional: Select backup and restore to create a backup of current installation on the Samsung Galaxy S II.
Select the option to Wipe data/factory reset.
Then select the option to Wipe cache partition.
Select Install zip from sdcard.
Select Choose zip from sdcard.​- The next step is "Select the CyanogenMod update.zip. "
The problem is I don't see the CyanogenMod update .zip file anywhere in that list. Seems like I may have placed it in the wrong sd card?
When I try and reboot it just comes to the screen with the giant S and goes no further.
How can I resolve this problem?
Adding some more information after reading a few other threads.
- Looks like I placed the cyanogen mod update .zip file in the external sd and not the internal one (stupid!!).
Now I cannot get back inside the phone to try and place it in the internal sd.
How do I solve this?
Connect the phone to the PC and mount usb in recovery. You should see a storage device in windows & then just copy the files on it.
Ok. Just tried that. After I select 'mount usb storage', the next screen says on the top:
USB Mass Storage device
Leaving this menu unmount
your SD card from your PC
I then see an option to unmount.
On Windows explorer, I don't see the device.
Thinking back, I may have unchecked 'USB Debugging' before I started the process (for some reason that I cannot remember now). Would that cause a problem?
USB Debugging should not matter because you're in recovery.
I've not understand at well the question. You want flash the CM9 from clockwork mod? I've a Galaxy Gio, but in my case i have only to:
1 - copy the ROM in the root( after flash with manager of Android, with an SD adapter or in the other possible way)
2 - backup the old rom from cwm;
3 - reboot in cwm and if i have mount errors of /cache /data or some other partition i format it and mount it manually from cwm
4 - flash the zip i've copied at step 1
Then you have to wait and at the end, reboot.
What goes wrong in these steps for you ?
EDIT: If you don't see the .zip try to remove SD and use a SD Adapter, so you can copy files manually. Or if you want use CWM you can mount the device connecting device with USB cable, go in clockwork and do "mounts and storage -> mount USB storage" and copy files in the root "/"
You can use adb push command in recovery to push files to the phone.
You can also use fastboot to flash image files to the phone.

Step 1 went wrong
I copied the ROM in the external SD instead of internal sd. Now trying the adb option to push the ROM into the device root. Hoping that works.

This guide is same as my gio guide. The ROM goes in the root of external sd, not in internal memory. Try to reinstall CWM if you don't find the zip.

Thank you my friend. This worked!
Little did I realise that this simple sounding statement above would require me to set up a complete android development environment on my computer.
I'm still not sure if all that was needed but I was finally able to get the files on my device by doing an adb push.
Lovely education for me today!
Glad it helped. Sorry I forgot to mention that ... it's kinda natural to me (having the sdk installed).

You should use the CWM 6.0.1.0 version. Also, the best idea is to use a secondary SD card, not the internal storage. You will notice that in the recovery, the option names are wrong. The one that says "external" is actually your internal storage.

You need to copy it to the external card if you're staying stock, either in /extstorages or /emmc, depending on hc or ics. Sdcard is your internal partition

Here is what worked for me. I got a lot of help from a lot of people on this site, so I want to share the knowledge.
I downloaded two files (which are attached to this post).
Put both files on your EXTERNAL SD CARD. If you don't have one, get one.
Boot into recovery mode. To do this, shut off your tablet and then press the power and volume up button at the same time. When you see the Samsung logo, let go of the power button only. When you see the next graphic with the android you can let go of the volume button. You should be in recovery mode now.
Use your volume up/down button to highlight 'apply update from external storage' Press power to select
Use your volume up/down button to highlight cwm.zip and press the power button to select it
** When cwm appears DO NOT use the volume +/- buttons anymore. Instead use the touch screen to do the rest of the procedure
In CWM use your finger to choose 'install zip from sd card'
Now, (not sure why) use your finger to tap 'choose zip from internal sd card'
Use your finger to scroll down until you see the root.zip file that you copied to your sd card and tap it
From here, you're good to go. I have no idea why I had to choose the option to choose zip from INTERNAL sd card, especially since I didn't do so. But, regardless, this worked for me. I installed Superuser and Titanium Backup without a problem.
I hope this helps you. I am by no means an expert at anything Android, but this site did go a long way with helping me out. I hope I was able to do the same for others.
One thing I did not understand is why, when I was asking for help with rooting my tablet, people suggested I use Mobile Odin. Mobile Odin requires the tablet be rooted to use it, so using Mobile Odin to root isn't possible unless I am misunderstanding something.
Edit: Now I am embarrassed. I just found this, after the fact.
You're almost there!

I got confused with that too, but I succeeded:
Sorry, Christiaan, but YES, there on the bottom you will find INTERNAL CARD too.
When you choose INTERNAL CARD, in fact it uses you SD CARD.
After choosing INTERNAL CARD, you will see your SD CARD folders. Then you will be able to root it!
go ahead, man!

[Completed] Wiped all system data, now stuck on cwm custom recovery mode

I am a complete newbie to rooting. I followed the kingoroot guidelines and rooted my Idea Aurus 3 phone. Root was success. The next step I did was downloading custom recovery and cyanogenmod ROM from here to my memory card
I flashed the custom recovery with flashify. The next step I did was wiping all data from the device by entering in to recovery mode (including cache and everything)
I was hoping I could simply install zip from sd card. But when i click on this option, I cannot find my sd card nor zip file (I checked most folders including emmc, etc, sd-ext and couldn't find SD card. The custom recovery name is Phylz touch 6
Now basically I have a phone without OS and all I can do is accessing custom recovery. I don't have a back up too
I can also see an error log "Cannot mount custom path"
I formatted the memory card to exFAT from exFAT 32 hoping that would work, it didn't help as well.
Also tried to connect phone to pc using USB (thinking I can move rom to system memory), but wouldn't detect phone memory
Now, is there any way to get this fixed? Any help would be awesome
Thanks!!!
