Can choose the place to backup ?

i want to backup nandroid also fail because seems like sdcard missing...or unmount

For your information, nexus 4 never have sdcard..
so missing seems a bit weird

The error message during nandroid backup fail is?

u did remove ur google account and then clear data for both google framework service and play store?

yes..i know about that..Just the /system/Sdcard is missing..smthing like unmount..i cannot access my data,backup or restore...

E:Unable to create folder ../data/media/twrp (errno=30)
E:failed to make backup folder

I just tried clear data for playstores and now I lost my play store apps. omg. what to do right now ?

I suggest you flash back the stock rom
Use the nexus toolkit to do it

i thought can be flash by goggle apps?

Sorry Im new to android.
Where to the flashback for stock rom ?Where is the nexus toolkit ?

Look in TWRP pages, see if there's an option to "mount /sdcard"

yes..but i cant check on..

Did you select external storage during backup? It should be the default one, internal storage.

yes..is internal storage..i tried to flash using nexus tools also fail.seems like i only can access roots files.

E:unable to mount '/usb=otg'?

Toolkit

Download the stock google image here

https://developers.google.com/android/nexus/images#occam

Install the Nexus toolkit in PC. Select install the phone drivers after launch
Copy the downloaded stock image ( a tgz file) to the subfolder " put your stock google image here " in the nexus 4 toolkit folder in PC
Choose flash stock image from the Nexus 4 toolkit menu
Your phone need to be in fastboot mode and connected to PC

Just reinstall your TWRP recovery and try again

reinstall TWRp using nexus tools?

You want better assurance do it from terminal:

Downlaod the latest img file from http://techerrata.com/browse/twrp2/mako

Switch off your phone. Boot to fastboot mode . Plug the phone into your computer. If you have the right drivers installed, your screen should now say FASTBOOT USB. Run the following command via the command line:

fastboot flash recovery recoveryfilename.img

Note that you will need to change the last part to match the name of the file that you just downloaded

hmm..mine keep remaining fastboot mode..that mean my driver wrong?
