I tried to flash cyanogenmod 12.1 with TWRP recovery, but when I try to install it, it shows an error- unable to mount '/usb-otg'. I don't have my phone plugged into anything, not my PC, no usb drives. I don't know what to do! Can someone help me please?
It shows that with every rom I flashed....with no problem at all.
So I ignore it and just flash away..
I am having the same problem. Any solutions yet?
Hi to all.
I'm using TWRP recovery system in my Nexus 4 phone, and I'm trying to downgrade from Lolipop 5.1 to Kitkat 4.4.4. When I'm at recovery trying to
flash my ROM and install Kitkat OS, a error message appears at installation telling "unable to mount e:/usb-otg", and the process to install stops.
Now, I've not got any OS at my movil phone, what can I do ?

hey guys, im back with stupid questions...
I wanted to upgrade my Nexus 7 32gb UMTS to 4.3 and used the Nexus 7 Toolkit (by Mark Skippen).
I was on a custom Rom and wanted to get back to Stock, so i could just use the update process by Google.
Downloading and Installing the ROM (including wipe of user data) by the Toolkit seemed to work and didnt show any error messages.
As is tried to boot my device into Android I got stuck in the bootloader.
When I tried to start it, a small white message "Booting failed" appeared in the top left corner. Nothing else happend.
I did everything again, no changes.
Next step was to google for a few mins, then I tried to install a custom recovery via Toolkit (which worked) and install a zip-file Rom via sideload.
Connection was there, the files got pushed onto the device but then "An Error Occured" popped up and everything stopped.
Installing a zip via usb-otg seemed promising, but this got me errors like "unable to mount /system" and "unable to mount /cache"...
when I tried to reboot from TWRP or ClockwordMod Recovery (tried the earlier described things with both recovieres) I got a message saying
"there is no OS installed, are you sure you want to reboot?"
Please help me, I really dont know how to fix this and I will need my Nexus 7 in 2 days (thats why I tried to reinstall and polish everything )
thanks for your help, I really appreciate it
Edit: tl;dr
Stuck in fastboot, no OS is installed. sideload / installing ROM via ADB / installing ROM via usb-otg doenst work, most certainly because /system and /cache cant be mounted
so AFAIK the real problem is that I cant mount those partitions, otherwise I could install a ROM and get out of fastboot/recovery easily. (just mounting them in custom recoveries didnt work btw)

Well . what you can try for now is download the latest factory images and flash them manually via fastboot .. See how that turns out. You can install any ROM via fastboot .. No issues what so ever.
In the factory images there will be a bootloader IMG.. Flash that first and then flash the remaining images ( I suggest manually or via the .bat or .sh files ) and then see if you can boot up android. Mostly should be possible.
And did you try rebooting inspire of the message " no is installed " appearing on the screen ? Maybe it will boot a ROM ? I remember facing this message after just flashing a rom sometimes. So don't worry.
As long as you have access too fast boot everything can be fixed at least w.r.t software.

It worked!!! Thank you so much.
Still wondering why it didnt flash the factory image as a whole while flashing every part step by step worked perfectly fine...

Hello XDA Developers,
I had a device that was rooted on stock rom and recovery. What happened was that an OTA was installed and it went to the "boot verify certification" screen. I had to install Ubuntu to get TWRP running again.
I'm able to boot into TWRP, and I tried installing different ROMs, using adb sideload, from Stock ROM, ParanoidAndroid, and Madri-ROM.
The first one was able to install, but when I reboot the phone, I get stuck on the LG logo. I wait for an hour and it still does not do anything.
So now I try the other two custom ROMs, and I get an error saying "E:Error executing updater binary in zip "... .zip".
Then it reads "Error flashing zip '... zip'.
My question is: What else can I do to get this phone working again? I would like stock ROM, and preferably stock recovery back (Recovery is secondary).
Thanks in advance,
DaAznMan
Note: When I use adb sideload, the .zip file that gets transferred becomes a file called 'sideload.zip'. Is that correct? If not, what do I need to do to fix it?
Hello,
I'm trying to install a custom rom on my note 4.
I rooted successfully, and installed TWRP through flashify.
First issue I ran into is that the phone got stuck in a bootloop after installing TWRP. All fine I said, it's cool since I want to flash a ROM anyway.
I downloaded the ROM for my device, and after I clicked factory reset and tried installing the ROM, I got the error
Code:
unmount of /system failed; so such volume
I looked around online, some posts said that it's fine, the ROM will install anyways, but that's not the case. The ROM didn't install (the process is finishing way too quickly), and I'm still stuck at bootloops.
I'm running TWRP 3.0.2.0 (newest version), android 5.1.1, on my note 4 N910H.
I have access to TWRP and to download mode, and I can move files between the PC and my phone using an external memory card.
PLEASE HELP ME :crying:
Hey, people.
I've looked for another threats on this, but seems like others really don't work, or I did something wrong.
So, I had Cyanogenmod for 6 months in this device but I wanted to reset it to stock rom. So I flashed it using Odin and, it was failing all the time for some authentication error. I flash stock recovery to if it would do any difference but no. I installed back TWRP and it was saying "E: Unable to mount '/data'" and '/ storage' too.
Now I cant even boot cyanogenmod because it never quits of "starting apps" after the boot loading.
Soooo... What should I do to resolve this?
Please any details? Did you try to reflash TWRP? Where did you find stock firmware?
You know i flash my device through odin a plenty of time and had no problem at all.

Hello all, I unlocked my nexus 4 installed TWRP ( tried several versions) currently 3.0.3 and now TWRP bootloops..
Any thoughts or fixes for this ?
I added a screen capture, " could not mount /data and unable to find crypto footer" unable to mount storage, etc.
Did you try 2.87? Is the phone encrypted?
I haven't tried 3.0.3, but 3.0.2 works flawlessly on my N4, with device encryption.
TWRP seems to be failing at decrypting your data partition.
Does Android boot in normal mode?
I will try 3.0.2 and report back... thanks for the help!
