Help, i am unable to mount usb storage in recovery or instal zip from sdcard

After flashing to the pixel 1.60 rom on my nexus s , I am unable to mount any partition(ie system, sdcard, mount usb storage etc) in clockword mod recovery.
I cant boot to recovery then to clockword mod fine but when i try to mount usb storage
i get the following error
E:Unable to write to ums lunfile (No such file or directory)
However by pressing the volume down button and power button I am able to load in to the O.S. fine with everything working including "turn on usb storage".
So does anybody have a clue on what is going on or how i can fix it.
You help in the matter is greatly appreciated. Thank you.

did you try going into the mount menu in recovery and mount the sd storage manually?

Ok I finally got everything back to normal.
It was a weird problem, I restarted into fastboot then into recovery for like 6 or 7 times and then finally I could mount usb storage. Then i loaded and then flashed the phone to the codename android rom 1.40 and now everything is working fine.
The thing is I do not know what caused the issue and how issue cleared up.
Anyone has any thoughts?

Working fine for me. Note also USB mounting in recovery is fully recovery and /boot dependant rather than /system dependant.
Sent from my Nexus S using xda premium

Error may nor be rom dependent.
Ok i do not think the error is rom dependent as it happened again.
This time, will surfing Wikipedia on android mod 1.4 my phone froze.
After plugging out the battery and plugging it in again, the problem appeared again.
1)Phone stuck at " Google" logo screen.
2)When booting into fastboot then recovery, the same problem occurs again
which is I am Unable to mount usb storage or "E:Can't mount /sdcard/" when choosing to load zip from sd card.
Could the problem be faulty flash memory ?
I have only about a month of warranty left.
If you guys think its faulty flash memory, anyone has any tips on how to flash to stock rom and lock the bootloader with the above problem?

/data error format and mounting

Suddenly my tablet went all apps to "Force close" so I immediately reboot my tablet...When I it boots it takes me hours and hours to boot and it doesn't work..
I'm using V8 bootloader when I go to CWM and do some formatting I notice that my /data couldn't perform a format or mount it then when I go to install .zip my internal storage couldn't opened as it recognizes it as /sdcard error mount. Is there a way to put those back again? I'm worried that I couldn't use my tablet anymore

[Q] In recovery: "failed to mount /cache (unknown error 150)"

I have a G2 that wants a decryption password on startup. It's rooted, and with stock recovery.
I reflashed with the LG tool, and did a "wipe data/factory reset" in recovery mode. The password problem remains.
I noticed that recovery mode complains "failed to mount /cache (Unknown error 150)". I'm assuming that's why I can't install custom recoveries or firmware using adb sideload.
Is there a way to fix the /cache mounting problem, or to allow full adb access, or install a custom recovery?

[Help] Yureka stuck at Cyanogen boot logo.

Hello Folks,
I performed wipe cache partition on my device after which it got stuck at cyanogen screen.
Its running CM12.1 and the default recovery. Also one of the main issue is that it is not responding to fastboot commands<waiting for device>.
I also performed wipe data/factory reset and wipe media now whenever i try to update via sd card it gives me error
Unable to detect E:/can't mount like something error.
Any Solution???

Mojo bricked ?

Hi had cm 12 installed it got stuck in a boot loop . I can enter recovery but it won't let me wipe . Keep getting an error message about e: partion . Tried to flash over the top and still get error on install of e partion . I think somehow the internal partitions have got messed up . Any ideas ?

Flash the new TWRP 3.2.1 image (copy it on your external SD card), then enter again in recovery and retry wiping.

Yeah I would definitely try the newer TWRP. You'll probably have to connect it to a PC to flash it though if you're stuck in a bootloop. I had to do this recently myself as I had the same problem. Make sure to read the thread on the new TWRP as you will likely have to select a mount option before wiping.

as soon as i try to mount system it locks up

Don't wipe anything, because you have first to flash the newest TWRP 3.2.1 image
After that, reboot the Mojo again in recovery and try doing the wipe with the new TWRP
