[Q] TWRP nor CWM will successfully wipe/format data

First, I searched and read all relevant threads concerning this issue. The five threads that showed up in the search did not help me solve my issue.
So on to my problem. I can no longer flash any rom onto my device. I attempted to flash the first official CM10 nightly (which I recently found out was not flashing properly for others) and had no success. I simply got a black screen and nothing more. I eventually got back into TWRP (v2.2.1.4) to try and Nandroid restore, but I noticed that /data was not formatting and the restore failed. Every time I would slide the bar across to confirm the restore TWRP would reboot itself. I then flashed CWM (v6.0.1.0) and the same problems were there. After that I flashed an earlier version of TWRP and successfully restored the backup. I'm not 100% sure how it was successful. So I decided to try flashing another ROM and no go. Same problems. Anyone have any ideas? When I was using CWM I got the error message below.
Code:
E: unable to locate volume information
E: unable to open ums lunfile '/sys/devices/platform/usb_mass_storage/lun0/file'
E: unable to format data
I'm running Bugless Beast with Motley #219

I'm having similar, if not identical problems. After flashing TWRP 2.2.1.4, I tried flashing a rom and gapps; the tablet would boot endlessly into recovery. Nothing I did would do anything, so I flashed the stock image to start over. This time, I used CWM 6.0.1.0 touch to make sure that it wasn't the recovery that was causing the problem. However, now after flashing the rom and gapps, instead of booting into recovery, I got stuck at a black screen and had to hold the power button in order to get back to the bootloader.
Now, like you, it seems I can't flash any roms anymore. It's frustrating to say the least.

So do I.I attempted to flash the first official CM10 8.18 nightly and had no success. I just got a black screen.Even more I boot into bootloader and choose to boot into recover but just stay at google logo.I try to flash recover once more,but just can't boot into recover!!

I have the same problem, i flashed the cm10 nightly which I learned would not boot. No I have no backup to boot to, and cannot even push a new rom to the storage to try to install.

There is a bug with the Nexus 7 where you cannot access the recovery through the bootloader. To fix this, boot up into the bootloader on your nexus 7 and, without doing anything, plug it into the computer you used for rooting it and then select the option Restart bootloader and press the power button. Once it gets you back into the bootloader again select Recovery mode and press the power button. It will now get you into the recovery and once you're in recovery you can unplug your tablet from the computer. Note that this fix is not permanent and you will have to do this every time you wish to access your recovery via the bootloader (and this problem is not relevant to the OP's problem).

Thank You Very Much!!!

I am having much the same problem as the OP. I finally rooted my Nexus 7 using WugFresh's Nexus Root Toolkit. It seemed all went well. I chose to use TWRP in a first attempt to install a ROM (I was on rooted stock), and following the instructions for installing my chosen ROM I went into it to wipe cache, Dalvic Cache and data. Both cache and dalvic cache wiped without issue, but when I attempted to wipe /data TWRP simply reported that it failed. With that failing, I did not attempt to install a rom. I was still able to boot out of recovery, but even with repeated attempts wiping data always failed. Is any one aware of any solution or have any suggestions. Thank you!

[Q] [Solved] Factory Rooted

Hello all, I just had a quick questions for those of you who have unlocked / rooted your Nexus 10 and installed the factory image:
1. Did you all use the toolkit in the Android Dev Forum for Nexus 10 to achieve the root?
2. Once you flashed a custom recovery was installing the factory image as simple as downloading the zip from google (https://developers.google.com/android/nexus/images#mantaray) and then flashing it via recovery and rebooting AFTER you unlock the bootloader etc?
I was under the impression that once you Unlock / Root, you have no OS on your device, is this correct? Or can I root and Android 4.2.1 will still be there, albeit completely wiped of my user data from before.
Thanks for the help, don't wanna get started on this until I know what I'm doing! Don't want a $400 makeshift frisbee disk

You can achieve root in a number of ways including flashing the SuperSU zip found in the How-to Root thread(s) or flashing a ROM with root already built in through the custom recovery.
Unlocking the device does not usually (is not supposed to) remove the OS but it does wipe data back to factory default. There has been, however, an issue with 4.2 on the N10 that causes it not to boot until you go back into Recovery and either factory reset there again or flash the stock image from Google.

Thanks! I think I will go through with using the toolkit tonight and see if I can get it to boot into the factory image. Glad that it sticks around (hopefully) if not I can just flash 4.2 from google via TWRP...thats what I needed to know

So really all I need to root is this:
1. fastboot oem unlock
2. fastboot flash recovery [recovery.img]
3. Boot into recovery
4. Flash SuperSU.zip? --- Where can I download SuperSU.zip ?
5. Wipe Cache / Factory Reset via TWRP wipe data
6. Reboot
7. Profit?
I won't use the toolkit if I don't have to since I am familiar with some fastboot stuff

Sounds like you know enough to do it without resorting to a toolkit, yeah. This zip file from http://forum.xda-developers.com/showthread.php?t=1997227 is one place to get fastboot drivers and the SuperSU.
http://downloadandroidrom.com/file/Nexus10/Nexus10RootNew.zip
I'd recommend (although it may not be necessary) making sure your devices fully boots after unlocking and wiping before going back to recovery to flash SU. Again, this is just because of the unlock boot loop issue that didn't happen on pre-4.2 nexus devices like the Galaxy Nexus.

I just finished successfully rooting...got hung up after I unlocked the bootloader and flashing TWRP but all I had to do was Format the Data and wipe cache after to successfully boot into the OS. After that I was able to load SuperSU to my SDcard and then flashed it, reboot, did root-checker and I'm all good! Thought I was screwed there for a sec cuz I didn't pre-load SuperSU or the factory image in-case it hit the fan and I wasn't able to mount my SDcard storage via TWRP...Figured it all out though thanks for the help! Glad I was able to do it without the tool-kit!

Lack of recovery

Hey guys, I'm a longtime XDA browser but hardly ever post. I have the MXPE rooted with the newest TWRP build and has been running great since I got it. last night flashed the Deodexed 6.0 build from AICPs 5.1.1. I had some issues with the SD card being mounted as internal storage and erasing something so I tried to flash back to stock as my nandroids weren't seen as usable.
Long story short when I flashed back to stock, the recovery would never take. I've flashed the stock recovery and twrp to no avail. For some reason it wont actually stick. Everything else is back to stock but that. When I used the win toolkit and tried to flash twrp again it said something about the folder locations so I'm wondering if I messed something in the partitions.
Question is, have you guys ran into this issue or have any insight on where to go from here? I've looked around but I couldn't find a post that the same as this issue. As a side note, I can get into the bootloader just fine.
I appreciate any info that someone can provide.

Flash twrp. Reboot back to recovery from recovery. Reboot system.
Hopefully it's that easy. Stock os flashes stock recovery on boot. Rebooting recovery from recovery prevents that from happening.
From TWRP:
"Note many devices will replace your custom recovery automatically during first boot.... Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install."
mxpe 6.0

Thanks for the info ffejy462. What happens when I try to flash TWRP and it doesnt stick? I know for a fact that I can boot into it temporarily with fastboot boot and the recovery file. Should I just flash it from there?

I'm sorry I didn't see this sooner. Flash recovery with fastboot. Boot into recovery. From reboot menu in recovery, select reboot recovery. Twrp will patch so recovery isn't lost again.

Please help, possible bricked phone???

Hey guys so my phone appears to me to be bricked. I have a rooted angler on stock 7.0.0 (NBD90X, Oct 2016). I have ElementalX kernal.
A few weeks ago I was looking in to putting on MultiROM. After I flashed the custom TWRP recovery for MultiROM, the recovery wouldn't work. It just goes to the TWRP blue startup screen and freezes. I have been procrastinating on flashing a functioning recovery ever since. I know, I'm an idiot. Lesson learned. Well the November security update was pushed to my phone a few days ago. I ignored it. Last night I wanted to see if the update included 7.1 or if it was just security update, so I tapped on the update notification and it automatically downloaded the updates without prompt (which I did not want to do.)
Well an hour later my phone died. When I plugged in to the charger, it immediatly started up by itself and booted to the non-functioning recovery and froze. It does this every time I try to boot the device now. I booted in to the bootloader and tried plugging in to my PC to flash a working recovery, but the device will not get picked up by the PC anymore. I don't believe it's a driver issue I use adb all the time with this same device and pc.
Also want to add, factory reset from bootloader went to google startup animation, but then just shut off as soon as it was done. Also, when I select shutdown from bootloader with it plugged in to charger, it will turn off and stay off but does not appear to be charging in any way.
Well that's the backstory. Any help you all can provide is very much appreciated. Turns out the battery in my backup phone is only good for a couple hours anymore. You all know how helpless we are without our phones, ha! Please help! Is it bricked?

I'm confused. How did you factory reset from the bootloader? That's done from recovery. Also, when in the bootloader you use fastboot, not ADB. ADB is not used from the bootloader. Only while booted into android or from recovery.
Use fastboot to flash factory images and you should be Okay.

I meant to say fastboot. Thanks for the clarification. When in the bootloader, scrolling through the options with volume rocker is a "factory" option. I assumed it meant factory reset?

Never messed with that so I'm not sure. Since your bootloader is unlocked just download and install what you need. Start by downloading and flashing TWRP. In the 6P original development section, find the thread and search it for 3.0.2-3. It's an unofficial version that fixes the issues since (-1). After you flash that boot into it and go to 'Wipe' > Factory reset. You can also do 'Wipe' > Advanced and select system, data, cache & dalvik. Do not select internal storage. After that download a factory image zip. Extract it and flash the bootloader and radio images from fastboot. Now extract the 2nd zip inside of the 1st one and in that folder you'll find system.img, boot.img, vendor.img, cache.img, recovery.img & userdata.img.
Flash those with the exceptions of userdata.img, cache.img & recovery.img. No need to flash recovery if you plan on keeping TWRP. Cache was taken care of from TWRP in the previous step and flashing userdata will wipe your internal storage. Plus you don't want to flash that anyways if your storage is more than 32gb. Refer to Heisenberg's guide for more info.
Edit: If you can boot to bootloader your device should be read with 'fastboot devices' - if it isn't, delete any Android / Nexus / Google drivers. **Reboot your PC** and install them again. After you install them again reboot your PC one more time and try again.

I can't get the PC/fastboot to recognize the device. I've never had a problem getting my pc to pick it up before. I even reinstalled the drivers.

How are you installing them? Using a toolkit? If so, stop and use the instructions in this thread. You shouldn't have any issues. Make sure you're rebooting your PC after deleting all Android / Nexus / Google drivers before installing them again. Install using the guide and reboot again.
http://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/page508
Edit/addition: Toolkits often use outdated or incomplete ADB/fastboot drivers. Always always always use the Android SDK to install them. That way you will always have the latest versions. If you ever have issues detecting your phone, just open the SDK and check for updates.

Okay so I left the phone on the charger with the frozen screen in twrp multirom edition. After that rebooted in to the bootloader. I then selected the factory option. If loaded the google animation like before, but this time actually booted up the system. The notification bar had two diagnostic tools that said tap to run...one was called sims i think? Anyways I held power button and did a hard reboot. It booted up fine. I then used twrp manager to install 3.0.2.2....then i used fastboot to flash 3.0.2.3 that i had a copy of. Things seem to be working fine now. Close call. I'm not sure what the factory option is in the bootloader, but it's not factory reset and it was the only way I could boot. I think the phone was trying to boot to recovery to install the latest updates and I had to boot to factory to get it out of "update mode," if you will...
Does anyone know what the factory option is in the bootloader?
Thanks for your help RoyJ

Factory options is meant to restart the system with some manufacturers apps available just so you can test certain functions of the phone, mostly to see if all sensors and hardware are working properly.

TWRP Stuck after upgrade to Nougat

Hello everyone,
i just flashed the newest Pure Nexus Rom and everything went fine.
I forgot to flash the SuperSU Zip so i tried to got back into TWRP, but now it stuck.
The System boots normally, only TWRP wont boot.
Anyone had that problem too?

if anyone else has the same issue, here is the answer:
I forgot to erase the userdata or cache.
If you have the same problem use fastboot!
fastboot format cache
fastboot format userdata
Then it should work again.
(Everything on your own risk)

If you dont flah SuperSU asap, TWRP will not stick on reboot (w nougat). That was the issue.

No SuperSU was not the problem.
It happened before i flashed the SuperSU zip.
As far as i know, there is a problem if you upgrade to Nougat and dont format the userdata and cache because of the encryption or sth like that.

Exactly. It happened before you flashed SuperSU zip. Not flashing SuperSU caused your problem. It needs to be flashed the first time you go into TWRP or you won't be able to boot back into TWRP. The previous poster is correct.

Maybe we talk about different problems
Ive formatted cache and userdata yesterday,
now i can go back into twrp.
(SuperSU is not flashed now).
Just tried it, works perfectly!

I never, ever flash userdata, and never had an issue.
We can agree to disagree. Either the other poster and I arent understanding your question, or you arent understanding our reply. It's cool, it happens.
But TWRP not sticking is due to not running SuperSU at the end of the install process. It wont stick.

And now i know the misunderstanding!
My sentence was a little bit silly formulated:
It didnt stuck by flashing SuperSU. I just forgot to do that and when i recognized this, i want to boot into recovery. Then i recognized the bootloop.
So SuperSU as itself was not involved. By the way BeansTown wrote in the Thread for PureNexus Rom that you have to format your userdata (normally over TWRP).
Shame on me that i didnt read before start flashing

So I followed the guide and updated to 7.1.1 and did the normal "fastboot flash recovery xxx" then "fastboot reboot bootlader" then rebooted it via phone I go to "Recovery" from my phone and I get a screen saying "No Command" I tried to flash twrp-3.0.3-0-angler.img
Did I miss something?

After flashing TWRP from the bootloader, go directly into recovery and flash SuperSU 2.78 or newer to make it stick permanently.

Hmm. If you are on stock, reflash the boot, system, recovery, and vendor from the factory image that matches your stock, security update. Restart the phone and boot into Android. Restart into the bootloader then fastboot flash recovery TWRP-angler.img. See if it lets you boot into TWRP then. If not, try an older version of TWRP and see if that will flash and allow you to boot into it.

Tried that, ended up going down an update in TWRP and it worked, weird....

I had a similar issue and I had to go back in and reflash Recovery image to recovery partition and all was well
