(((SOLVED))) Galaxy S4 - Sph-720T - Failed to mount /efs (Invalide argument) - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

In recovery mode I am not able install any ROMS, theres the error Failed to mount /efs (Invalide argument)
I can only flash stock roms using odin, everything works on stock roms except for the wifi, after connecting/disconnecting multiple times, the wifi stops responding and wont work in the future
---------------------------------------------------------------------------------------------------------------------------------------------
(( SOLVED ))
First thing you should do, is to backup your EFS if you still have it.
I had mine but it wasn't mounting properly.
In order to back it up, please download terminal emulator on a rooted device and follow this video
I would try to back it up, even if you think the efs is messed up... worst case scenario is you end up where you started, not worse off.
---------------------------------------------------------------------------------------------------------------------------------------------
Your device needs to be rooted.
1.) Download SDK tools here - Scroll down to the bottom and "Get just the command line tools"
2.)Install TWRP , Find your device, download the .tar and flash it using ODIN
Boot in to recovery, in TWRP you want to go to mount, make sure system, esf are checked.
3. If you installed SDK tools, go to c:\android tools\SDK tools. hold shift and right click on the area inside the folder and select run command line from here.
4.) In cmd, type
Code:
ADB devices
ADB Shell
SU
mke2fs /dev/block/mmcblk0p10
mount -w -t ext4 /dev/block/mmcblk0p10 /efs
5.) You should be good!!!

Please help me, my boot show error:

Do you have custom recovery? if yes, boot in recovery and access the phone via adb shell and check disk space with df. you will see the percentage of how much disk space is in use. if it is system, try to delete the boot sounds and some ringtones. if its data, delete the contents of /data/local/tmp (i suppose there are many apks there which aren't in use at all).
Hope this helps

Recovery Console / FW Problem

Hi,
well, since i rooted via recovery console (update.zip) and installed rom manager, that i have a droid and a triangle with a yellow exclamation point in the recovery console as background (i already hard resetted the phone, cleared all data, but the triangle still keeps there when i go to the recovery console... is this normal or do i have a problem in the firmware? I tried to install the update.zip from wavesecure from the recovery console and it gave error and didnt install, maybe it damaged the firmware... any tips?
Another question...since i failed to install wavesecure via update.zip, i used adb, copied the apk to /sdcard then i moved it to /system/app, its working now, but one of the commands i used was
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
do i need to change permissions with another command or it reverses that command when i reboot? Because on their site they say to do "mount -o remount,ro 0t yaffs /dev/block/mtdblock3 /system" after copying, but that command is invalid, is not working.
Thanks for helping
bump....Please help, mainly about the triangle with a ! in recovery, because if its an error with firmware i can flash another, im still with the stock one JF5

[TOOLS][ADB][Windows]Push files to device through ADB*now include deodex tools*

See my previous post before in post#2
This is a simple batch file using ADB..
With this you can use ADB to manage your file or APK , Backup, Push Your File to device, or pull file from device..
ADB Work on Stand by Mode (Home Screen) or in Recovery Mode, just set it up..
Extract ADBTOOLSv1.0.1.zip and you will find :
command.bat : Windows Batch Command
_BACKUP_OUT : folder where your backup process done and made
_FLASHING_OUT:
folder for flashing your :
kernel (place your boot.img here)
recovery (place your recovery.img here),
modem (place your modem.bin here)--only for gt p7300
_MODDING_FILE: Folder where your file were created by PULL process
Folder where file for PUSH process should be here
_BATCH_INSTALL : place your APK here for batch install
tools: ADB.exe and busybox binary
success_APK : A folder created for All apk from _BATCH_INSTALL move here after instalation.

Click to collapse
Notes:
ADB can access all file from device from CWM Recovery, especially CWMR 5.5.0.4
ALL you need to do is:
From Recovery menu, you need to mount /data and /system for ADB working..
THEN, From Command Prompt set ADB Mode to "recovery".(This Batch File set ADB mode to "Home Screen" by default)
So when you use ADB from Online device ( I mean a stand by device).. you dont need to change ADB Mode..
After you set up, you can use ADB as you like..

My previous post
inspiration from congox case
when you got a problem with bootlop and you forget make a nandroid backup
only have file from other ROM with flashable.zip and need to push the file from your computer to device
you have a recovery support with mount /system and mount /data (tested on CWM 5.5.0.4 and overcome CWM 5.1.2.6) and you can enter this menu while bootloop happen..
STEP 1 : MANUAL
Connect your device with computer
From device, Go to recovery - mounts and storage - mount /system and mount /data
From your computer go to adb terminal and type this
Code:
adb shell "ls /data/media/"
If you can see list of file from your device sdcard, so you make adb work for your device ..
Place your zip file on your path, says on C://backup.zip and you want to copy the file to /sdcard/download/ and type this code
Code:
adb push backup.zip /data/media/download/.
wait for copying progress done..
After you done with moving file to device sdcard, check content of your sdcard with this code
Code:
adb shell "ls /data/media/download/"
When you found your file from list, you can flash backup.zip from recovery
STEP 2 : WINDOWS BATCH FILE
I made a simple Batch File for windows (sorry i dont have MAC or LINUX distro) , this file will make a folder with name "emergency" in SDCARD and with your files inside that.
Extract the FLASHER.rar somewhere on your Local folder,example: on your " Desktop" Folder
in folder "FLASHER" you will find runme.bat and folder "files"
Rename your file ((flashable.zip files you want to send through ADB) to "backup.zip" and then Put your file into this path /FLASHER/files/myfiles/ (just replace the existing "backup.zip" with files from yours)
Connect your tab with Computer
Reboot into Recovery Menu from your device
From menu Mounts and Storage choose mount /system and /data
From your Computer go To Folder flasher and klik runme.bat
Follow the instruction on window untill copying process done and device reboot to recovery again (copying process will take a minutes depend on your file size)
Now you can flash a emergency ROM from recovery

Hope this help someone..
Nice guide, thanks!!
I needed some help with mounting the system using adb through a batch file.
I use this command
adb -d shell mount -o remount rw /system
But the mounting fails (I have a rooted phone )
pleas help me I know this is off topic
2 possible reasons for this command to fail:
- /default.prop (on the phone) contains the following line: "ro.secure=1". Then you need another boot.img (in fact just a modified ramdisk). look for "unpack-bootimg.pl" or "unpackbootimage" you may find a guide how to do this manually (not too easy). A rooted kernel would also do the trick.
you can check your default prob with this command "adb shell cat /default.prop".
- in some cases mount requires more parameters. try "adb shell mount" and look for the line containing "/system". In front of system is the "device-name". in my case the mount command would look like this:
mount -o remount,rw /block/dev/mmcblk0p24 /system
hope this helps and sorry for answering off-topic questions....

you can use busybox and call the binary from the shell
i assume that your device in normal mode ( in home screen)..
here some example..
Code:
su
adb push busybox /tmp/.
adb shell "chmod 755 /tmp/busybox"
adb shell "tmp/busybox mount -o remount,rw /system"
after you type "su" superuser will prompt a request, choose "allow".

[Q] [Help]

Hey i have really messed up my nexus 4.Please help.I'll tell you my problem in short:I have flashed recovery.img onto userdata by mistake using quikIMG.So now the phone got reset and the whole phone was seemed wiped.There was nothing on the phone.Thats what i assumed after peeking into galary/music etc but when i connected my phone to the pc it is showning that the phone's 10gb is used.Basically it is showing that the data is still there.Can you tell me any way to bring back the data?
Try factory reset
This may or may not work, no guarantees. This will be difficult, time consuming, and you must do everything exactly as written; so read it first and ask questions before you begin. I am using a Windows PC, most of these commands will be similar on other OS's, those when in the adb shell are identical. This will require adb and a custom recovery (I use TWRP, so I'll be able to offer TWRP specific help quicker), find a method to flash that before you begin, and find where that recovery keeps it backup files. Also this will require you to flash a rooted ROM, of the same android version you had before: if you had stock, I recommend you flash stock and root it; either way, have that ready to go before you start. Lastly, the worst case scenario will require you to have a linux system and possibly some kind of removable media (USB stick, external HDD, etc), you can just boot a linux live disk, and that's what I'll be doing with Ubuntu; again, have this ready first. There will come a point about mid way through, where, depending on the results you may need to wait for me to follow up with you, I will try to do this in a timely manner, but I can't promise anything.
Basically what we are going to do is explore the file system in an adb shell while it is booted to a custom recovery, hopefully from there your /data and /sdcard partitions will still be intact; if they are not we may still be able to recover some of your data. If they are intact you can simply use the recovery to make a backup of them.
And so, with your phone connected to your computer, boot to recovery. Then open a command prompt and enter:
Code:
adb shell
cat /proc/mounts
The output will look like:
/dev/block/mmcblk0p23 /data ext4 rw,relatime,data=ordered 0 0
/dev/block/mmcblk0p23 /sdcard ext4 rw,relatime,data=ordered 0 0
/dev/block/mmcblk0p22 /cache ext4 rw,relatime,data=ordered 0 0
Click to expand...
Click to collapse
First is the block, then the mount point, then the file system type, last is information about how recovery treats it.
If you do not see /dev/block/mmcblk0p23 associated with a mount point then enter:
Code:
mount -o rw /dev/block/mmcblk0p23 /data
mount -o rw /dev/block/mmcblk0p23 /sdcard
If you get an error on both of these then skip to the breakt.
Now check both these directories to ensure it is the data you expect it to be, enter:
Code:
cd /data
ls
cd /sdcard
ls
Maybe go down a few levels to confirm your data is really there. If the output doesn't look right, then skip to the break.
Otherwise, enter:
Code:
exit
Use the phone screen to navigate to the backups menu and backup data.
When the backup is complete use adb pull to copy the backup onto your computer, this may take a very long time.
Code:
adb pull /sdcard/TWRP TWRP
Now flash your ROM, including a data wipe, and boot it, once it is running fully, reboot into recovery and push the backup to the phone.
Code:
adb push TWRP /sdcard/TWRP
Use the phone screen to restore the data.
--------------------THE BREAK, cause XDA automagically made these two posts one, ****ers--------------------
Hopefully you got this sorted out with the first part, this part may not work at all, and it will be a lot more tedious if it does. So, at this point something happened which indicates /mmcblk0p23 really did lose the data, so we'll just copy the whole thing and explore that copy in linux to extract what data you can.
With the phone in recovery, and a command prompt in an adb shell:
Code:
dd if=/dev/block/mmcblk0p23 of=/tmp/userdata.ext4
This may take a REALLY long time. When it is done, enter:
Code:
exit
adb pull /tmp/userdata.ext4
This will take just as long or longer. Transfer userdata.ext4 to your removable media device. And boot to your linux setup. Open a terminal window in the directory with userdata.ext4 enter:
Code:
sudo mkdir userdata
sudo mount -o loop userdata.ext4 userdata
cd userdata
ls
Now if any of your data still exist in a form I'd be able to help you recover, it will be in this directory, userdata. If you see something that you recognize, or that you know you need, copy it and save it to the removable media. After that you can reboot your system.
Go ahead and flash your new ROM now, let it fully book, and then copy back whatever you managed to save.
I kinda lost steam there toward the end, sorry, it's 0316 here. If anything is unclear ask away. Good luck.

How can i copy Rom zip to phone, i formatted, no rom to flash but i have recovery

I deleted Rom file in sdcard. I cant flash a rom. I have recovery, root and Philz Touch.
How can i copy Rom zip file from computer to Phone? Any idea. I have rooted KK, i dont want to do all things again.
How to: Copy ROM zip file to the freshly wiped device
I found and share with you, it worked.
Have you ever been in a situation where you mistakenly (or not) wiped the content of the internal storage (including system partition and virtual SD card) on your phone or tablet and unfortunately it doesn't support external storage? Now you can't flash desired custom ROM because you removed it and the device can't be booted due to wiped system partition. Don't worry - it's very easy to fix!
Here are the steps you need to follow to copy the correct rom.zip package to your internal storage:
Download this mini-sdk package and extract it to c:\mini-sdk
Rename the custom ROM package you want to flash to "rom.zip" and copy it to c:\mini-sdk
Connect your device to the PC
Boot your device in recovery mode
Open a command prompt on the PC (cmd.exe), type and confirm each command with ENTER:
cd /d c:\mini-sdk
adb shell
mount /data (error might mean that /data partition is already mounted)
on Android 4.2 and above: mkdir -p /data/media/0
on Android 4.1.2 and below: mkdir -p /data/media
exit
on Android 4.2 and above: adb push rom.zip /data/media/0
on Android 4.1.2 and below: adb push rom.zip /data/media
Wait for a few minutes until the file is copied. It will looks like command shell is not responding, but that means it's still copying. Wait patiently until you'll see blinking cursor again.
Depends on your custom recovery, use the navigation keys to flash the custom rom.zip package in a typical way you used to flash custom ROMs. It should be on your internal storage now. Done! http://android-revolution-hd.blogspot.com.tr/2013/12/how-to-copy-rom-zip.html
easier solution:
*bring device in recovery mode
*open cmd, go to adb.exe
*type adb.exe push *filename.zip* /sdcard/your path **/sdcard is already linked to /data/media/0
*wait after pushing the file, reboot recovery again
*choose file and flash
*** other method ***
*use the sideload function in recovery
*adb.exe sideload *rom.zip* in cmd
it says usb device descriptor failed...is it due to bad cable??
