install TWRP Recovey, get in Recovery mode, choose Backup, tick EFS box, wait and done, reboot..
and then make a copy of efs on your emails, burn in CDs, save to a floppy disks, print the hex code on stone, always store in safe places...

Recovery file manager

Would like to point this out to peeps in our corner of the community.
I'm in no way involved in this.
It is fully touch based.
i just moved svoice from the sd card to system app with it, all while staying in twrp recovery.
You're first time you will have to change it's settings to mount all on startup
Just exit, then "flash" again

How to delete all files from phone?

When I wipe using TWRP, I still have some files left over in root directory. Do I have to clean those too to get a truly clean phone? Don't those files accumulate over time?
I can see those files in the TWRP recovery's file manager. How should I delete them? Some of them do not delete manually...

[QUEST] CWM backup from Nexus 4 to System

Hello guys ,
How do i copy the backup created using CWM to my system(laptop) ?
As i understand the latest CWM backups are stored in locations which cannot be accessed by users . Is there any other way it can be achieved ?
Also please do provide the restore procedure for the same.
On nexus 4 running stock kitkat.
CWM version : 6.0.4.3
Any help would be greatly appreciated .
they can be acesses by users, at /data/media/clockworkmod or /sdcard/clockworkmod, u can use root explorer or adb to get them.

Just plug your phone to your system(laptop) and look for the biggest by size folder. That should be your cwm backup. Also mind the name. I am not talking about /Android!!! Just copy it somewhere the regular way and then delete it. The restore is simple but you have to have it back on the same place in the phone's memory. The restore process is carried out from the recovery. GL.

AFAIK this partition is an exclusive partition on Samsung devices...

Yeah you're right! Is it a spelling error? Never heard of esf...
Nexus 4 doesn't have a efs partition.

If your friend is lucky few ROMs will take EFS backup in SDCard and there are tools which can restore IMEI number. If you do flash other roms then better take a backup of efs folder. using root explorer you can archive and store efs folder.

There isn't an efs partition on nexus 4. It's a samsung thing. Galaxy nexus had it because it was made by SAMSUNG
Backing up ur ESF Partition
U need Root,Android Terminal Emulator and busy box to successfully backup your ESF Partition. Type the following codes to backup/restore the ESF partition.There is another block mmcblk0p10 which contains the m9kefs3.img however the same is blank(So backup not mandatory). The m9kefs2.img contains the IMEI information. Also kindly backup the same to ur PC / Email or Drive
Also these codes remain the Same for Android 4.4(Kitkat) & 4.2(JB). However for Android 4.3(JB) change the storage path to storage/emulated/legacy
Code:
su
dd if=/dev/block/mmcblk0p8 of=/storage/emulated/0/m9kefs1.img
dd if=/dev/block/mmcblk0p9 of=/storage/emulated/0/m9kefs2.img
Restore.
su
dd if=/storage/emulated/0/m9kefs1.img of=/dev/block/mmcblk0p8
dd if=/storage/emulated/0/m9kefs2.img of=/dev/block/mmcblk0p9

Error during cwm backup

I keep getting this error when I try to do a backup from the ROM manager app.
E:unknown volume for path [/sdcard/clockworkmod/backup/1.2014-06-15-22.24.53]
Using the app to make a backup used to work. Trying to save to external.
How do I specify the destination?
I can the backup manually, which I've done via rebooting into recovery and choosing the option to install to sdcard1.
Idk what to do to have the app select the correct path.
Any help appreciated.

You don't say what operating system you are using and what version of CWM.
Edit: Your other post says you are now running CM11 and CWM v6048. That is why it is different, you just installed a new CWM. v6048 uses a different path for backup. I don't know how to fix it for you with ROM Manager.
