Install Busybox.
Install Terminal-Emulator.
In Terminal-Emulator write:
Code:
su
guarant root access
then type
Code:
busybox dd if=/dev/block/mmcblk0p1 of=/sdcard/efs.img bs=4096
You´ll have efs.img (your backup) on your internal Storage

In mounts and storage select mount USB storage. Plug your phone into your computer and it will pop up as USB storage and now you'll need to do a quick couple of folder creations as follows:
clockworkmod needs to be the root folder, inside that a folder called backup and then inside that put your backup (assuming you just have the folder for your backup and not the whole cascade of folders.
Once you've done that simply restore the backup and you're golden.
Also, thank you for posting this in the correct section!

Only CWM on my TF101G B90...

Hi all,
I'm here because I need your help...
Days ago I installed on my TF101G the recovery CWM 5.8.1.8...
now I can just go into recovery mode and if I try to mount /data I receive the message "no location found"...
how can I push a Rom on my TF to try to install it?
thanks in advance for your help
how to flash a ROM
The ROM to be flashed must be cwm flashable, you cannot flash official firmware unless it is repacked to be cwm flashable.
Your ROM must be a zip file, do not unzip it.
Copy (or adb push) the ROM to /sdcard/
Reboot tab into recovery.
Follow cwm flash instructions. There are many such a manual available on-line, one of them is:
http://www.addictivetips.com/mobile...-and-how-to-use-it-on-android-complete-guide/
You can just jump to section "apply update from sdcard", which tells you how to use cwm recovery to flash a ROM
One thing you should pay attention is:
if the ROM to be flashed is only a update to your current ROM, do not do any wipe work.
If it is a new ROM, you must do the wipe.
You can also try this....
hi Fenice82,
read this forum
http://forum.xda-developers.com/showthread.php?t=1213723
and read message 1 and 313 for mounting and the adb commands for sending cmw flash file to your internal card of your TF.
Make sure you have the cwm flashable rom file on you computer in the adb dir.
good luck.
I'm hege again...
thk nlheiz for your post...
I push the rom in my TF... I tried different location...
data/media
or
data
or
system
or
sdcard
or
sdcard/rom
if I go in adb shell and I use command mkdir to make a new folder like system,data,sdcard I see the the file already exist...
but my tf "can't mount /sdcard/" and at the same time if i try to mount /data from recovery I see the message
"Error mounting /data!"
what can I do now?
edit... maybe this can help you...
via ADB shell
mount data
mount: mounting /dev/block/mmcblk0p7 on /data failed: Invalid argument
How about restore stock recovery and ROM? Here is a recent guide for root/unroot/downgrading:
http://forum.xda-developers.com/showthread.php?t=1622628
I don't have experience with cwm 5.8.1.8, I stayed on 3.2.0.1 because it is possible to flash from external sdcards.
cold you try this:
put our tablet into cwm (volume - plus power and when asked volume +) and connect it to usb on pc.
then on your pc:
adb devices
this should give you a serial number back.....
then try this:
to mount the internal sdcard so that you can push a new rom- use
adb shell
mount /dev/block/mmcblk0p7 /data/
ls /sdcard/
exit
then from your pc, type:
adb push /path/to/your/rom.zip /data/media
I found this here http://forum.xda-developers.com/showthread.php?p=23256536 in post 3......
let me know if this works

[Q] ADB Push and internal storage

Hi all,
I accidentally deleted internal storage while I was trying to flash paranoid android on my Nexus 5. I then managed to push the ROM.zip back into my phone's internal storage using ADB Push. I installed the ROM but after the ROM installed, the zip file is no longer in the internal storage. What happened to the zip package? Where did it go?
Thanks for your help in advance.
/data/media
Sorry
The media dir is blank. I used the command as ADB push ROM.zip /sdcard

It isn't blank. You're just using a file explorer without permissions to view it.
If you used CWM recovery when you adb pushed, its as already state by @Aerowinder... . In /data/media because CWM recovery still mounts /sdcard as /data/media instead of what android 4.2+ mounts it as which is /data/media/0

I used TWRP v2.6.3
I will look in TWRP Mount settings if I can configure the permissions.

What permissions?
Sent from my Nexus 5 using Tapatalk
You're right. There are no permissions to configure in TWRP file explorer.
Should I switch to CWM?
Just boot into android and use a proper file explorer with root access.
Or you can use adb and Linux command line to
mount /data
ls /data/media
To see if the file is there.
Also I know with Philz recovery when you formatted /sdcard, the 0 folder from /data/media/0 was gone leaving only /data/media (until a commit was made to recreate 0) so its possible TWRP does the same making /sdcard temporarily mount to /data/media
Anyway not sure where it is if its not there
No don't change to CWM

Samsung Galaxy S6 failed to mount EFS ! Please help !

Hi,
My device is kind of bricked, since it doesn't boot up due to EFS mounting problems.
I tried to restore through adb but there is no /dev/block/mmcblk0p3 location.
Any ideas how I should restore the EFS folder (i have an efs.img saved in my pc) ?
Thanks !

There is no mmcblk0p3 for galaxy s6.
Efs mount can be found in the block > /dev/block/sda3

Dont forget to mount /system partition in custom recovery before doing adb commands

Thanks a lot!
I managed to make it boot, now is usable but still, if I type *#06# it shows me a generic IMEI 3500...06/02 and my SN disappeared, and when I flashed a stock rom have the same problem (stuck at logo).
I've been flashing UniKernel again with odin and all was good.
Is there any chance that I can run stock rom and kernel, and make this go away?
Thank you again !
Hmm ur imei i guess is broken. Did you tried to backup first and restore the efs?
Im not sure but im unable to get my phone to stock . Only custom recovery works for me.

Is it possible to restore dd backups with fastboot?

Hello every one,i recently became familiar with the "dd" command which can backup any partition on ur device e.g you can backup the recovery image to your sd card using dd if=/dev/block/mmcblk0p21 of=/sdcard/recovery.img now my question is,since my phone (Vodafone smart grand 6 vf-696) doesn't have a custom recovery and root and can't restore using "dd of=" since this one writes partitions and requires root,can i make "dd backup" images of my system partition and restore them using fastboot since they are image files?

yes, but you arent going to be able to pull the img's without root.
Alright thanks for the answer..my last question:.. I have a Sony Xperia C with Cwm recovery,i wiped it recently and now i can't mount data,cache and system and in the log in says "cant mount /system:invalid argument".. Can i use the " dd command" on another xperia c to copy the data,cache and system partitions in /dev/block to restore them on my device?
