Hi all,
I bought a white N4 today since my GNexus died on me.
I played a but with the phone and went on to rooting.
I unlocked bootloader, but now the phone won't boot!!! it doesn't go pass the Google coloured cross.
I can still go to fastboot, so I flashed CWM recovery. Tried to wipe data, but it seem it can't mount /sdcard . . .
Please help I have no clue what's going on and fear I bricked a brand new phone
Thanks

Boot into CWM and wipe cache. If that doesn't work, flash the stock recovery, boot into the stock recovery, and wipe cache.

No luck with wiping. I flashed stock recovery, but when I boot to it I get a laying down droid with red exclamation mark...

That is the splash screen for the stock recovery. To access the menu, hold the power button and press volume up.
Then wipe cache and reboot. If that doesn't work, factory reset and reboot.
ok got it.
Flashed stock recovery, wiped everything, locked bootloader. I guess I am 100% stock now.
Phone is booting ok.
I will try to use Nexus root toolkit to
1, unlock
2, flash CWM recovery
3, flash superSU
Hope it will work ok now.
What is your take on what happened ?

What method did you use to unlock the bootloader the first time?

Have a read of the "return to stock" sticky in the General section. Sometimes the N4 won't boot if you have flashed images. You need to either format userdata (i.e., factory reset) or wipe cache.
No need to use a toolkit to do what you want.
1) Unlock the bootloader: fastboot oem unlock
2) Flash CWM: fastboot flash recovery cwm.img
3) Boot into recovery and flash a superuser zip.
everything is now fine!
Thanks Efrant!

Hello!
I was on the HKTW build as of yesterday. I have Tenfar's recovery and CWM installed too.
I attempted to install Kennith Penn's Alien Rom V2 and it seems like its flashing no problem... However, I get stuck in a boot loop.
I tried restoring to a previous back up , and that loops now too
So, I attempted to flash 2.3.4 Fruit cakes ( http://www.multiupload.com/U1EOJVAKPO ) and it seems that it is flashing it properly, because I got back my stock "AT&T" boot logo (from the factory) but, that goes into a boot loop too...
Can anyone please help point me in the correct direction of getting my device to boot the rom/ image properly? Is there a setting I need to ensure is checked on CWM (like mounts or something?) ... at this point, I cant even boot into Tenfars recovery... just CWM...
This sucks!
Thanks in advance for any help!!!

Bootloops in 99.9% cases means that you need to wipe.
1. Go back into CWM, wipe data / factory reset, wipe cache, go to advanced and wipe dalvik cache.
2. Flash the desired rom.
3. Go into CWM again and do all the wipes again.
And you should boot no probs.
p.s. these 3 steps should your blue print to installing any rom btw. even you want to backup apps - use TB.
thank you for your help....ive actually dome all of that and still no go

Have you tried wiping via fastboot?
moto-fastboot -w
p.s. do you have the latest CWM recovery? there can be problems if you arent using the latest one.

+1. i was having the same problem not too long ago and that fixed my problem.
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!
This isn't my first android root but I'm stuck. I followed the video for rooting my Nexus 10. Got stuck in a boot loop but was able to flash cwm but still in boot loop. I tried doing the factory reset and now cwm is gone too and still stuck in boot loop. Do I need to reflash the stock recovery and if so where do I find that to download?
flash tbe cwm recovery again via fastboot, transfer your custom rom of choice from your desktop to your device, wipe data (factory reset), then flash that rom via cwm. btw, this is a galaxy nexus forums

and the recovery flashed fine? did you "fastboot devices" to make sure fastboot can see your device? sometimes these recoveries need to ne flashed a few times before they take. try flashing it two or three times in a rom. did you try twrp recovery? you might like that recovery better.
op, rename/delete /system/recovery-from-boot.p and reflash your custom recovery;
RANT: GOD DAMN IT, WHERE'S MY NEXUS 10!!!??? BEEN WAITING FOR 2 GODAMN MONTHS! - Sorry, it's just that I've been going through some **** to get my hands on one - AND THERE'S PEOPLE WHO'S GOT 2!!!
FOLLOWUP:
I ran MSkip toolkit and it repaired everything. I got a failed on renaming my recovery images so my stock recovery images are just gone I guess? Anyway I'm good. Rooted and repaired thanks to Skips toolkit.
Thanks for all the help!
-------------
It appears to be flashing fine and yes it sees my device. I tried multiple reflashing this am and still no joy.
I reposted in the right place and got some help but not done yet. I think mod might delete this thread since I have the other one going.

I tried doing the factory reset and now cwm is gone too and still stuck in boot loop. I tried reflashing cwm. When I try to access recovery I get the red triangle with ! on it. And I'm stuck in boot loop. I went here and tried to reflash recovery.img and no joy. Still no recovery access and no boot. ((
accidentally posted this in the samsung nexus forum #whoops
Boot back into recovery and press all 3 buttons (power, vol +, vol -) simultaneously until the menu comes up. The timing has to be very exact so don't worry if it takes 10+ tries. Then select factory reset and it should boot up properly.
I never could get CMW to stay. So I flashed TWRP as the recovery instead. Also follow wireroid advice about getting out of boot loop. If you want to SEE that method, check out the rooting N10 vid on youtube by qbking777.
some progress!
Ok I got back into the tablet with wireroid help YAH!!
I have a system update pending but when I tried to install it I got the red! with 'no command' ... after a near heart attack I did the factory reset again and got back to where I was before.
Now I need pointed in the right direction. So right now I'm unlocked but that's it. I have no custom recovery and presumably no su access because all I successfully did was unlock the bootloader.
I downloaded the nexux10 toolkit. Do I need to flash a recovery first? Do I try CMW again or go with TWRP? I've only used CMW in the past.
Do I ignore this Jelly Bean system update for now??

Try this toolkit by Wugfresh. http://www.wugfresh.com/nrt/
It's what I used and I went from locked and stock to unlocked, rooted, and with TWRP as my recovery in less than 15 minutes. I unlocked and rooted my GNex the "old-fashioned" way but wanted something easier for my N10.
Also, here's a YouTube video from QBKing77 walking you through the process using the above toolkit. https://www.youtube.com/watch?v=YtLvlrUDB04&feature=youtube_gdata_player
Since you're already unlocked you should be able to just skip to the part where root and a custom recovery are flashed (you'll end up with TWRP but you can always download ROM Manager and flash ClockworkMod if that's your preference).
Good luck.

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.

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
