Hey guys, this is my first post on XDA forum.
So I've recently bought a nexus 7, I used wugfresh's root kit to root my nexus but then it didn't work... so I've tired the auto root by chainfire. Then I was able to get root. So then I went to playstore and downloaded rom manager to install CWM. I went to recovery then I get this message:
E : Cant mount /cache/recovery/log etc.....
I've tried everything I can do such as researching, changing recovery, and watching a youtube tutorial but nothing helped.
Thanks.
I would start over from scratch using fastboot to flash a factory image and stock recovery. If your bootloader isn't unlocked already, unlock it.

I tried to format using wugfresh couple times but still not working...
DO NOT USE TOOLKITS. They cause too many problems. Learn to do things the proper way using fastboot. I agree with the poster above, you should flash a factory image to start over. Download the system image from here- https://developers.google.com/android/nexus/images
You need to unlock your bootloader-
Code:
fastboot OEM unlock
Then run the flash_all.bat. That will automatically wipe and reflash everything to get you back to square one.
Then you need to flash TWRP (don't use CWM)
Code:
fastboot flash recovery recoveryname.img
TWRP will automatically prompt you to flash SU when you reboot. Choose yes, reboot, then install SuperSU from play store, update the SU binaries, reboot again, and then you're done.

I highly advise you start from scratch so do what I told you to do in my last post. I promise if you do it the correct way (ie. without using toolkits) it will work.

It's in the file that you should have downloaded from the link I posted in my first post. The instructions are at that link as well.

Hey I tried the following:
oem lock
oem unlock
flash-all/flash_all.bat
flash recovery(TWRP)
but then when I reboot into TWRP I don't get a message saying you to install SU... And when I go to 'Install' in TWRP I don't see any internal storage available(0mb). With this error I cant install any roms which is boring.

Hmm... Can you even boot into the stock ROM at this point? Try formatting /data (done in TWRP). Did the system image flash successfully?

Well then I don't know what to tell you at this point. I know Lollipop has been causing issues for some N7 users, but I also know that wugs toolkit causes problems too so honestly I'm not sure what the root of your issue is. I think someone with more experience with Lollipop is gonna have to chime in here, I'm still on 4.4.4 on all of my devices. Sorry I couldn't be of more help.

No, you can only flash custom ROMs if you have a custom recovery.

Are you sure that you can't reboot in twrp ..did you already try to do it manually ?
anyway if you want go back stock and you aren't able to use again NRT you need to flash manually a factory image from Google .Here is a the link with instructions ;
https://developers.google.com/android/nexus/images
if fastboot flash doesn't work you probably have fastboot locked.

Are you able to get back into system? If so, run this command with an active ADB connection.
Code:
fwtool vbnv write dev_boot_fastboot_full_cap 1

Hi. I was wondering if you know how to fix this only through fastboot. I get the same "remote: unsupported command" message when flashing partitions and "remote: image verification failed" when using "fastboot boot twrp.img" command. Right now, I have no recovery and cannot boot to system. Locking and reunlocking bootloader doesn't change a thing and I do have the latest drivers.

No, I haven't gotten it to work. As far as I know, there is only one way to fix it and it involves opening up the tablet, as per this post.

Unzip it, open the folder until you see a bunch of files.Click the back button, select the folder, press Shift and click the right side of the mouse, and select open command window here.use the command fastboot devices and report back.

Unfortunately the picture is too small to read from it. It is great! It means your device can receive fastboot commands! I can guide you how to install stock Oxygen os 3.2.7. That also means you lose your data from internal storage. Do you want Oxygen os 3.2.7?

Fyi, if u decide to go back to 14.1, you will need to flash modified twrp http://forum.xda-developers.com/devdb/project/dl/?id=21065&task=get
Then recovery will stay intact
Hello,
I unlocked the bootloader and when I want to boot into twrp (not flashed it, just with fastboot boot recovery.img) the computer says it was ok, but the op logo and "fastboot mode" appears on the phone's screen for a couple seconds and after that nothing. What did I do wrong?
