My N7 ended up in a boot loop after the 5.1 update. I can get to the bootloader and I can get to recovery. HOWEVER, the bootloader is still locked and the debugging mode is not enabled.
In fastboot, I can send the OEM unlock command, but the N7 screen just blinks and comes right back to the bootloader screen saying that the current status is locked.
I can go to the recovery screen and get to the option to sideload, but when I try to sideload the system file, it always says that the footer is wrong and that the signature verification failed. I've tried several different files from the Android factory images.
I've also tried the Nexus Root Toolkit and the SkipSoft Toolkit and they don't seem to work either.
ANY help would be appreciated.
Welcome to the bricked N7 club. Same thing happened to mine after taking the OTA 5.1 update.
+1 Also the same here Lock state - Locked nothing works, also the recovery mode is not working on mine (think I wiped the device somehow)
Anyone know how to fix the recovery mode also? I cant Flash recovery as the bootloader is locked?

I'm still struggling with this. I've tried the Nexus Root Toolkit v 2.0.5 and it doesn't seem to do anything. I can tell it to unlock the bootloader, but at the top of the screen it just says "unlocking now........" and never unlocks it.
Starting to get really frustrated......

Hey all,
I just got my nexus 7 wifi, rooted using Wug's tool kit, installed TWR latest version and installed CM Rom.
The problem I'm facing is that when I want to boot into recovery mannually, i.e. powering on the device with holding volume down and up, I succeed into booting to the bootloader. However, when I choose the reovery Mode option, the nexus enters into a boot loop [ if that's what you call it ].
Yet if I use the toolkit, or use the commands in software like goo or ROM managers to boot to recovery, the phone does boot into recovery.
So I'm fine for now, but if anything goes wrong in future, I will get stuck. I tried, but Even the toolkit couldn't get the nexus into the recovery mode when it's in bootloader. It has to be open, and Not in File transfer mode.
I'm very noob in these things, so I would really appreciate you explaining in simple terms.
Thanks in advance.
Update to latest bootloader version 4.23 then erase and reinstall TWRP.
Thanks, I did update I can boot via bootloader now.
I recently just picked up a nexus 4 and i'm trying to get a custom ROM on it. I updated it to 4.3 and that was fine. Went to install custom recovery and every since it will not boot! I've reverted to factory 4.3 using fastboot, and relocked it and locked it but still will not boot. It gets stuck at the X logo. Left it for an hour and won't get past it. If i install a custom recovery, it'll boot into the custom recovery no problem, but won't install root as it can't mount the SD card. I can get to fastboot mode no problem and flash stuff in fastboot but will never boot up. I'm puzzled as to what to do. I'm going to try 4.2.2 factory image here shortly and see if i can get it to take. I forgot to enable USB debugging so i think thats why i can't get custom recoveries to work. I tried pushing a ROM using ADB push but it wouldn't get there. Maybe it did as it said it did on the computer but the recovery won't read the memory. Any ideas as to what to do
UPDATE: Ok after flashing stock 4.2.2 from fastboot it boots.
UPDATE: turns out just having USB debugging was the culprit of everything. So make sure USB debugging is enabled before starting the whole process!
Hey everyone, recently I've bought a nexus 4 that was soft bricked, I can access the fastboot and recovery, I tried flashing using The nexus toolkit to flash but its always stuck at boot loop, I tried using commands to flash , it will loop boot, I tried factory resetting after each flash but nothing helps..I am able to see the phones storage too, any ideas how to get past the loop? Thank you in advance!

Just flash a factory image straight from google. Need to be more specific with errors if you want help. Did the bootloader unlock ok? Was it already unlocked?
Try flashing 4.2.2 image rather than the latest, some hardware issues can prevent the newer firmwares from booting.

I tried flashing 4.4.4 then the first jelly bean, it was already unlocked , im able to access the download mode, fastboot and recovery, like i said I tried 4.4.4 and oldest jb but its still in boot loop, any ideas?
There were no errors at all, using the nexus toolkit or using commands
Lock your boot loader then reboot. Is the padlock gone? If it is unlock the boot loader and retry. If your boot loader will not relock or unlock after relock you have an emmc issue. If it all goes through fine but still won't boot it's also probably a hardware issue but maybe fixable.
Ok- I need some help. If anyone cares to comment or point me in any direction it would be greatly appreciated.
TL;DR - tried to flash stock image and it still doesn't work.
My phone basically committed suicide last week for no apparent reason. No physical damage with the device that I am aware of so I presume it is just soft bricked. I attempted the usual clear/wipe cache and the stock recovery factory reset to no avail.
After turning it on it will just be stuck at the red Motorola "M" logo. Right before it got put in this boot loop a few system apps crashed so I rebooted (Google Play, Google Chrome), and the phone never came back up.
I do not have root, nor an unlocked boot loader, which seems to be why I can't load any custom recovery stuff (tried fastbooting the Clockwork Recovery image).
I've attempted to flash the stock image (VZW_XT907_4.4.2-KDA20.62-15.1_CFC_1FF.xml.zip) from sd_shadow's stickied post[1]. According to RSD lite the flash is successful, but its still stuck in the boot loop
One thing I noticed is that the AP Fastboot screen doesn't actually print out anything other than "usb connected" during/after flashing. I would think it should print some diagnostics, or at least a success message. I'm suspicious because the AP Fastboot screen will print security or sizing error messages when it fails.
flashboot screen reads:
PHP:
AP Fastboot Flash Mode (S)

Nope, and my guess is I would need the bootloader unlocked to get any further. The Razr M doesn't show up on this list so I'm not even going to bother

any Motorola with Droid in the name, and Verizon on it, will not have an official unlock option
Sent from my XT1080 using XDA Labs
I had been using my phone with no issues for some time (on Nitrogen 7.1) and at dinner I took a picture and then tried to upload it to Facebook. It froze when I tried to do that and ever since, it has bootlooped.
It shows the unlocked bootloader warning and then Google splash screen and that's as far as it gets. I can't get it to boot into TWRP via the volume buttons, but I can get it into the bootloader. It also wont boot into TWRP via the bootloader menu option. I re-flashed TWRP from fastboot but it didn't change anything.
I realize I should be able to factory wipe it with fastboot, but is there any way I can recover my data or better yet get recovery going again?
