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?

sdcard works in recovery mode but not with system booted?

once system is booted it says sdcard is blank or unsupported file system, but the same card works on my Windows machine and my smartphone, and it works on my tablet when in recovery mode, one thing to note when i was formating the system it said cannot format /sdcard/.android_secure
i ran chkdsk in windows and found no errors so i reformatted everything again since i saw an error last time and after doing a double wipe of everything just to be safe then reflashing rom it worked again.

TWRP

Hi, I installed TWRP recovery, but I can't mount storage, when I clickin mount, nothing is happening, PC dosn't see any drive...

Nexus 4 - broken screen, encrypted, can't enter lock pattern at boot

CM13, MultiROM TWRP 3.0.0.0
Touchscreen doesn't react to anything.
I connected mouse via OTG with external power and TWRP can use it, so I can decrypt and mount /data in recovery. But when Android boots and asks for lock pattern, it can't see any otg devices. I tried flashing other kernels, such as Quanta, Revival and HellSpawn, but nothing works. Adding android.hardware.usb.host.xml also doesn't help.
Is there any other option to get phone fully booted?
Thanks.

Phone memory corrupted, 0mb displaying in TWRP, help me fix it

Hello,
I have an old Lenovo A6000 Phone which has corrupted memory i assume. It does not want to flash even after letting it sit for 8 hours straight the download is stuck and when booting TWRP 3.1.1-0 x64 image it displays 0mb internal storage but reads the sd card fine.
It used to work fine, I had AOSP installed in it with the HEX-FIRMWARE-PATCH FOR ARM64. if my memory didnt fail me, it stoped working after i tried to restore it to the original firmware.
NOTE that twrp recovery doesnt boot and its stuck in the loading screen of lenovo, I ACCEESED IT THROUGH FLASHING IT RESTARTING BACK AGAIN TO BOOTLOADER THEN BOOTING IT IN FASTBOOT
NOTE THAT IF I DONT FLASH IT AND RESTART IT DOESNT BOOT FROM THE BOOTLOADER AND IT JUST GETS STUCK.
i have managed to run 3.0.1 x32 and 3.1.1-0 x64 and both show 0mb memory and DOESNT WANT TO REPAIR THE PARTITIONS NOR WIPE THEN AND UNABLE TO MOUNT.
i have an old twrp 2.7.1 but it doesnt work, i guess from the patch.
From what i have read around here, there is a way to reformat or repair the phone through the terminal command but it was for another phone and i am a bit lost what to specify for the partitions on this phone.
If anyone has an idea how to fix it or can just give some hints where i can find the blocks names it would be really helpful. Thank you!
