Trying to install a Custom ROM for the first time on Nexus 7 (3G).
I've been using the WF Nexus Toolkit.
I've rooted, unlocked and flashed ParanoidAndroid but I'm only getting a bootscreen loop. I waited 15 min before rebooting the device and attempted to boot into PA again. Still not getting past the Bootscreen.
I booted into recovery; did a full wipe then flashed the PA ROM again... Still not getting past the Bootscreen (waited 30 min before powering off the device)
I've tried to obtain help via IRC before posting here; as well as reading through other post directly related to the problem (even a few that were slightly indirect) but nothing I find is helping... so I've turned to you guys!
I would very much like to get this ROM working, so if there is anyone that can help I would greatly appreciate it.
I just don't know what to do next; I've never had this issue with any device in the past.. I've usually been able to figure the problem out and get it working. But now I'm just stuck.
What is your recovery? What steps did you do in recovery to install the rom?
Try these step may help.
1.Boot into recovery
2.Full wipe
3.Wipe Cache
4.Wipe dalvik cache
5.Flash ROM, GAPP
then reboot your N7.
...
If above method still doesn't work. make sure you have the right version of bootloader and stock image on your device for PA 3.15 or newer it should be 4.18 for bootloader and 4.2.2 for stock image (optional).
And if you've found that you have other version of bootloader than 4.18 check this http://forum.xda-developers.com/showthread.php?t=1907796 thread for how to get it right.
...
Finally if you've done all the solutions above and still in bootloop problem just try to do a factory reset (full wipe) again after finish flashing ROM, GAPP.
That's all I can thinks of about this problem base on my personal experience facing bootloop problem few months ago.
If you are still stuck after trying the above posts. You can just try to get back to stock. Nexus Root Toolkit maybe the easiest way to do that..

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.

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!
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!
I've encountered a strange problem with my nexus 7. As soon as I install a custom rom (I've tried the latest nightly of Carbon and Slimbean) with a full wipe my device does not boot up. It stucks on the carbon, respective slimbean, bootscreen. Another strange thing is that the latest CM nightly seems to work without any problems.
I even tried to flash a factory image and then reflashed the recovery (TWRP 2.6.3) to try the mentioned custom roms again. Still no luck - CM did work again.
So, do you guys have a solution to this problem? I've used both roms in the past as my daily driver, so I am out of ideas for now...
No suggestion, but I just flashed SlimBean on mine from a full wipe, and I'm having the same issue.
I tried SlimBean again, and it worked. Here's what I did:
1. Updated my bootloader. Mine was still 4.13, and it looks like the most recent version is 4.23. I flashed the img from this post using NRT.
2. Went back to unrooted stock with NRT. (I had to update my bootloader to do this.)
3. Let it boot back into unrooted stock, wept with joy, made a nandroid from NRT.
4. Flashed the SlimBean 1.9 weekly and minimal gapps from NRT's advanced area.
5. Watched in amazement as it boots obediently. Let sit about 10 min, and rebooted.
I'm essentially lazy, so yes I used NRT instead of manually pushing everything with ADB. ADB was plan B. It was briefly plan A, but I got tired of trying to convince the Android SDK that I did in fact have the Java JDK installed.
Mhhhh....

I am trying to flash my N4 with cyanogenmod following the official wiki.
I'm at the point where I've installed TWRP into recovery, I've wiped everything (I've even formatted them since I couldn't wipe all of it initially), and the only error I see is "unable to mount /usb-otg".
Then, I've "installed" the CN zip files for the 13 and 12 versions, none of them works in the sense that when I reboot the system, I'm always coming back to TWRP.
What's wrong? Any suggestion?
Thanks
I've the same problems with my nexus 4

Hi gerardgerard,
I also wanted to flash my Nexus 4 with Cyanogenmod 12.1. So I installed TWRP into recovery and wiped everything, like it's explained in the wiki. I can also see the error "unable to mount /usb-otg". When I want to reboot the system I always get back to TWRP. Cyanogenmod doesn't boot correctly. Did you find a solution for the problem?
same problem
Hi
I'm having the same problem. As follows:
Cause (my mistake): I have been using Cyanogen-mod nightlies for a couple of months on my Nexus 4, and made the grave mistake of leaving the phone to upgrade one night but without it being plugged in properly - and it ran out of power part way through! (At least, that's what I think happened).
Fortunately, it would boot into bootloader and I could use adb/fastboot. I (re)installed TWRP 2.8.7.0 (from my Mac, using fastboot). And that works fine - I can boot into twrp ok.
Next I loaded the latest nightly from cm (using fastboot - is this what people call sideloading?) and used twrp to install it. It goes through the installation fine (the only error message is that it can't mount /usb-otg). But when I reboot it just goes back to twrp.
I then tried installing the earlier cm nightly that I know worked, but with the same result.
Finally, before I first installed cm I did a backup (using twrp), and I have tried recovering that. It seems to do all the right things, but again when I reboot it just goes back to twrp.
Any suggestions would be welcome.
Thanks
J
Flash back to a completely stock ROM and run through the set up to make sure everything works. Then copy CM to the phone, reboot to fastboot, flash twrp, immediately boot into recovery using the volume and power button without leaving fastboot, wipe data, cache, system, flash CM, reboot.
If the phone will not boot after flashing a stock ROM, boot to fastboot, flash the userdata.img file, and immediately go to stock recovery without leaving fastboot, wipe data/cache, reboot.
It works now!
I managed to fix the problem ... I found this guide for the Nexus 5:
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
and I applied those instructions. It didn't work first time, so I just repeated them and now it's working. I used the 5.1.1 stock downloaded from https://developers.google.com/android/nexus/images#occam.
I guess this is what audit13 means in their post - so thanks are due there.
I will next reinstall twrp and cm and I don't expect any problems with that (having done it successfully before).
