[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] Nexus 7 - Stuck in Boot Loop

Device Model: Google Nexus 7 16GB
ROM: PARANOIDANDROID 2.99 PIE3.1 (4.2.1)
Recovery: Clockworkmod Touch Recovery 6.0.1.9
I installed this ROM at the root of my SD card and wiped the dalvic cache. When I try to boot it, I'm stuck at the "X" boot screen. I've already reflashed my device 3 times and this bug is still there. I was just curious if anyone has seen this issue and if there were any workarounds?
I'm able to flash my device back to Stock but I really want to get this ROM working so a little help would be appreciated!!

First of all, that's not a brick. Not at all. You need to read the installation instructions, which would have told you that wiping data is a must.

Re: [Q] PARANOIDANDROID 2.99 - Bricked Device
You don't need a workaround. About a million purple have installed PA. What ROM did you try and flash over and are you sure you had the right file for your android version?

Not a brick. If you can flash something else it's not a brick.

Before I flashed anything, I was using Stock 4.2.1 but once I started flashing ROMs, I've been stuck at a boot loop even though I've wiped the data and dalvik cache. I seriously can't figure out what's going on.
ROMS flashed: CM10, LiquidSmooth, ParanoidAndroid, MIUI, SmoothROM
Recovery Tools: CWM 6.0.1.9, TWRP 2.3.2.1 (I have tried both recovery tools for each ROM when performing installation)
Each time I've been stuck at the boot, I had to reflash the Stock Image to recover. After I flash the stock image, I would try to flash another ROM. It's not like I have any data on here either so wiping the data isn't really helping as suggested...
The steps that I've followed:
1. Unlock bootloader
2. Root Device
3. Flash ROM using either CWM or TWRP.
4. Wipe Data + Dalvik Cache
5. Reboot System.
Is there something wrong with the steps I'm using? I've been using the Nexus 7 Toolkit 4.0.0 to make things quicker but it seems like I should just use the adb shell and manually trace it step by step.

Nevermind, I figured it out. I did a factory reset before the flash and then wiped all the other stuff in order for my Nexus 7 to boot properly. Thanks for the feedback!

Android 4.3 stuck at "Android is upgrading"; "starting apps"

My friends, who is miles away tried upgrading nexus 4 through official OTA but during the process, phone stuck at "Android is upgrading".."starting apps". It been in this state since an hour. It's not even showing how many apps have been upgraded out of the total apps.
The phone is fully stock. Not rooted. USB de-bugging not enabled.
Can anyone please help?

First to a hard reset/reboot, if not working:
Go into recovery > wipe cache.
If its not working wipe data (factory reset)
IF that doesn't work, try flashing stock images.
IF that doesn't work, flash a custom recovery and wipe cache dalvik cache and format/wipe data(I prefer twrp) (when unlocking bootloader and flashing recoveries I also recommend using the fast boot commands, not a toolkit)
If that doesn't work, then flash a ROM?
Flashing stock images should be your second to last last option though,
Flashing custom recoveries/roms IS your last option.

Bro thanks lots for your response. However nobody here replied so i took a guess avid asked her to reboot the phone and see if it starts up. Fortunately it did and luckily it updated the OS. I wonder why it stopped at upgrading apps then?
However her camera ain't working, which was already giving lotsa problems on 4.2.2.

[Q] Yellow Brick?

Just recently rooted my s4, was working fine or so I thought, went to flash NamelessROM, I don't think the rom is the issue, I had my s2 rooted and flashed on a weekly basis so I know about wiping, data cache, and dalvik, I flashed Rom then Gapps, and it was stuck on boot up, of course I made a nandroid and restored, but now I'm stuck on the yellow sprint screen, did my research and found it it's called a Yellow Brick, or referred to as. Found out a possible fix was downloading the kernel so I've chosen the Rooted NoData kernel to download and flash via odin. Is this what I should do or is there a better fix out there?

Sounds like you wiped everything. Can you boot into recovery?

Yes I can, and I tried to restore back from my nandroid which is how I'm stuck on yellow sprint screen now versus stuck on the boot for NamelessROM.

Do a factory reset in recovery and see if it boots.
That will wipe your accounts and what not but you can't boot anyway.
If it won't boot then you'll need to flash a ROM to get running. Do you still have the ROM you wish to flash on your SD card or internal storage?

Just got me stuck on NamelessROM boot up so I'm restoring off nandroid again. I think that flashing the kernel will fix it.

I'd get the ROM booting then play with the kernel. That's just me though.

I'm trying to push a kernel through odin, I could possible try to find a way to put a kernel on my extsd and try and flash it through twrp? Would I just have to wipe cache and dalvik and flash? because when I try through odin it fails.
EDIT: I found a fix it involves unrooting most likely, but if I do I'll be back at VPUAMDC (Android 4.2.2) so could I still root with SafeRoot? Or what would be the way to root from that version?

Which firmware version did you root from? If it was MJA or MK2 you have to use one of those, you can't downgrade to MDC easily.

I think my system portion is corrupt... Any chance of saving it?

I have a 2012 Nexus 7. At the time it had a locked bootloader but it was rooted with cm11 & TWRP on board. I downloaded the Nexus toolkit & tried to upgrade to lollipop when it was officially released. Somewhere along the line, I think the system partition got corrupted. I can manually flash all IMG files except system. I can get into bootloader & recovery. I even tried flashing TWRP again to reflash cm. TWRP took but cm failed to install. Anyone else have this issue? The tablet appears to boot but it just gets stuck at the Google screen with the lock at the bottom. Never goes past that point. Any help to revive this tablet would be much appreciated.

Can you enter recovery or fastboot mode? If so, use either to attempt and repair (format) the system partition, then reflash the ROM of your choice.

In Twrp recovery,
1. go to wipe menu and advanced wipe.
2. select system partition then tap repair.
3.Flash your rom

Ok so that worked to flash cm but will this continue to happen if I try flashing the official lollipop update? I'm trying to return to stock so I can give the tablet to my nephew. I don't want him jumping into recovery or bootloader & wrecking it for good
