Not sure why you are restoring system or what you are restoring it from.
When you are stuck on the Verizon logo do you have ADB access still and can you boot back into recovery?
If you can successfully boot back into TWRP, I would suggest:
1) Downloading/installing the restocked 1.2 kernel
2) Flashing SuperSU again
3) Clearing cache and dalvik
4) Reboot system and see if everything is working.
If you are unable to boot into TWRP recovery (either through ADB commands or using the hardware keys on boot up) then you'll need to take extra steps.

so I could use some major help! I received my new nexus yesterday and I believe i've already soft-bricked it somehow but I can't seem to recover it. I've read that you should change the APNs from the cingular ones to the new att settings. I did this, and then I rebooted phone, but somehow it got stuck in a boot loop. so i was like S%^T, and all. so like a moron I started messing around in fastboot and I unlocked the bootloader through cmd line. I found this article http://forum.xda-developers.com/showthread.php?t=2010312 which I figured was my best chance for a recovery. I also tried the Nexus Root Toolkit v1.7.1 and told it i was softbricked / bootloop scenario. I've tried loading the twrp, cwrm, stock recoveries, but evertime I try to boot to the screen is on, but blank. i dont get the android with the !..
NOTHING is working!
I think my major problem at this point is i NEED usb debugging enabled, but I cant get into android gui itself to enable this option.
Believe me ANY help is greatly appreciated and I'll but you a pizza and have it delivered to your home...:laugh:
This should be easy, just put your device on bootloader and use this tool, make sure you have the ADB and Fastboot files with it all.

Done this also. I used the 4.2.2 files for Mako. Then followed the link instructions that I posted from that link.
1) Make sure your computer recognizes your device by typing: fastboot devices
2) Unlock your bootloader (if you have not already done so): fastboot oem unlock
3) You will see a prompt on your device. This will wipe your entire device (including the /sdcard folder). Accept. Note: you use the volume keys to change the option and the power button to accept. You cannot use the touch screen.
4) Reboot by typing: fastboot reboot-bootloader
5) Flash the bootloader: fastboot flash bootloader bootloader-mako-makoz10o.img (or whatever the name of the bootloader image that you downloaded).
6) Reboot: fastboot reboot-bootloader
7) Flash the radio: fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1700.48.img (or whatever the name is of the radio image that you downloaded).
8) Reboot: fastboot reboot-bootloader
9) Flash the system partition: fastboot flash system system.img
10) Flash the data partition: fastboot flash userdata userdata.img Note: this command will wipe your device (including /sdcard), EVEN if your bootloader is already unlocked. See note 2 below.
11) Flash the kernel/ramdisk: fastboot flash boot boot.img
12) Flash the recovery partition: fastboot flash recovery recovery.img
13) Erase the cache partition: either a) fastboot erase cache OR b) fastboot format cache <<== the second option seems to work better for most people. Thanks joostburg.
14) Reboot: fastboot reboot
15) Done! The first boot will likely take quite a bit longer than you are used to, as Android builds the Dalvik cache.
At step 8 it doesn't reboot saying it failed and I have to hardboot back into bootloader from every step forward where required. Eventually I can flash all the img files and reboot phone. I'll then see and android logo with a blue rotating sphere and status bar, then reboots. it does this several times then screen goes blank.

Well I was able to run the "flash-all" batch file with success, no errors or bootloader reboot issues. Phone rebooted again and now I'm suppose to be waiting for Dalvik Cache to rebuild. This is about 10 mins ago though, any ideas how long it takes to do this??

Should take around 10-15 min. If its taking more than 20 minutes i would suggest going into the bootloader, then into the stock recovery and doing a factory reset from there.

USB Debugging is just really a ADB switch for the OS.

Installed 4.4.1 via TWRP this morning, but it is stuck in reboot. Just keeps doing the colliding circles!
Tried rebooting a couple of times. Can get to fastboot, But device isn't seen by adb, and fastboot only shows start (no recovery option)
Any ideas at this point?

I would recommend flashing the 4.4 stock factory image from here in fastboot mode. Then once your device is booting up properly again I would recommend taking a look at this guide to properly install the 4.4.1 update.
You MUST either side load or safer still, un-root(if rooted) and flash stock recovery and sideload and then re-flash custom recovery and re-root if needed.
If you are able to get to fastboot:
Fastboot flash recovery recovery.img ( use stock)
Fastboot reboot-bootloader
go into to stock recovery - wait for dead droid, one you see him, go into recovery by holding volume+ and power at same time
follow the orange instructions to sideload via adb - which should now work
reboot and validate all is well
reboot into bootloader and re-flash your custom recovery and root (if needed)
Enjoy.

If you mean stuck at boot animation, then I suspect you used TWRP to flash?
I found that TWRP was not able to clear caches, so I use CWM instead. Worked like a champ...

No I used the adb sideload command for the OTA. That all went well but now I'm stuck at the google page even before the animations begin!

Hold volume up and power to get it to recycle, and immediately hold all three buttons down to get to bootloader. Try clearing your caches from recovery

Hi,
Try flashing it fresh stock again, factory reset your device from recovery, download the stock image file from here, untar it, then unzip the zip inside the tar and you'll get some files (.img). Copy those files to your fastboot folder and then open a cmd there. (Guessing that you're using Windows)
Code:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot flash cache cache.img
If you're using Linux, do the same, but instead of only fastboot use:
Code:
sudo ./fastboot
Then boot it. I had the same problem when I updated mine to 4.4.1, but I did one thing a little different... Instead of fully "stocking" it again, I flashed back 4.3, flashed 4.4 OTA and then let it boot, without wiping my data, after all it was running like this before. Worked. But as I'm unsure of your situation I think it's more secure and easier to fully stock it again.
Hope this helps,
~Lord
PS.: Remember to put your device in fastboot mode!
Need help here!
My Nexus 10 was with stock 4.4.4, rooted with TWRP. I decided to flash the factory image files by removing the -w in flash-all.sh. However it ended up with being stuck with the rotating balls. After about 45 minutes, I decided to go to the fastboot mode (pwr+both volumes), then select recovery (I planned to do factory reset and clear cache). After trying to reboot into recovery mode (pwr + one volume button), it now shows an open bootloader with following message below the bootloader (the bootloader seems still unlocked):
Dowloading...
Do not turn off target!!
What does it mean? What is it exactly downloading? And what should I do? Should I lock the bootloader? Also it does not respond now if I push the volume buttons. It's not recognized on my Mac with the with the following command:
fastboot devices
I also notice the following line:
Reboot Mode Flag: NONE
Now I just booted into recovery, but it shows the bootloader with the exclamation mark! After a few minutes, it automatically switched to the never-ending rotating balls. What can I do?
When you get the Downloading...message you're in the Recovery screen. Don't worry about the message. Press vol up and power to get into the recovery menu - there you can wipe cache and system. As you're in recovery, Fastboot devices will not recognise your tablet, only adb commands.
If I was you and this didn't work, I'd just reboot into fastboot and flash the image files manually. You'll lose root, data and twrp but these can easily be gotten back through fastboot.

OK, 3 days ago I rebooted my ZE551KL and it went into a bootloop. I was completely 100% stock. No root. Locked bootloader. Spent the better part of the weekend trying to troubleshoot it, and I have made almost zero progress.
I've tried a bunch of things, but here is my current status.
Can get into fastboot mode no problem.
POWER + DOWN VOL gets me into stock recovery, but at some point I flashed an older version. I tried flashing TWRP, but after install could never seem to get into it (is that because I'm unrooted and locked?)
Current recovery version: Android system recovery <3e> LRX22G.WW_user_1.16.40.763_20151201
I've tried flashing to a couple different firmware versions from the ASUS website both via ADB and via the SD Card.
Current firmware: UL-z00T-WW-1.17.40.1531-user.zip
Still in bootloop.
Any advice on rebuilding this thing from scratch? I dont care whether I just get stock back, or if I need to root/unlock, install TWRP and a custom ROM. Dont care, just want a functioing phone!
Thanks in advance.

I dont get it. Did you factory reset your phone? With stock rom, factory work most of the time.
You said that you tried flashing TWRP. If you see successfull message after flash, type "fastboot reboot" and hold volume down button right after hit Enter. If you did right, you can get into twrp, then choses Wipe > format, it more powerfull than factory reset.

1. Factory reset from within the phone's OS? No, I cant get that far. Just constant bootloop on ASUS logo.
2. I've used the fastboot erase command to wipe everything, and used the wipe data/factory reset option in the stock recovery. Still bootloop.
3. I've tried flashing TWRP 3.0.0.0 and the newest version of TWRP. I hold down the VOL DOWN key before hitting enter on "fastboot reboot"; it just goes into a faster bootloop, like every half-second. When I release the VOL DOWN key, it goes into the same, slower original bootloop.
ACFH said:
Ok. You can format through fastboot
Code:
fastboot format userdata
fastboot format cache
If it still stuck in bootloop, try reflash boot and recovery, fastboot wipe system. Then copy update.zip to sdcard. Boot into recovery > install update from external sd.

Awesome. I'll give that a try and report the results.
I just downloaded the .img with the same date as my recovery version from here. https://asus.kremowka.xyz/categories/show/2
Its been hung at "Verifying update package...." for about 10 mins now. Once this is finished (and probably fails ); I'll give your format commands a try.

In a bootloop that shows ASUS logo for 10-15 seconds, flashes a blue screen really quick, then reboots.

My Nexus 6P started bootloping a couple of weeks back. It used to bootloop upto the "Google" logo, but occasionally used to go past that and start up. I followed the step-by-step guide from here:
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928
I did the following steps:
1. How To Unlock Your Bootloader
2. How To Install A Custom Recovery On Your Device
6. How To Root
and
8. How To Install A Custom Kernel With TWRP Recovery
This, however, didn't help me fix the bootloop issue. I read on a different thread that restoring to stock has helped some folks. So I followed:
10. How To Flash The Factory Images (Return To Stock)
Now the phone sometimes reaches up to the "flying color dots", but never goes past beyond that. Can anyone help me with this situation please?
I tried to go into the Recovery mode, but that doesn't help either. After selecting "Recovery", the phone bootloops as usual. But eventually goes to "flying dots".
Any help is greatly appreciated.
Are you flashing it with the flashall script or flashing the files manually?
I had the exact symptoms the first time I flashed 7.12 because I had erased the cache partition before I realized it was no longer included. You can try: Download the last version of 7.11, which would have been around April, and extract the cache.img. Copy it in with the other images and follow 10 (or 9) in Heisenberg's How-To again and include the two fastboot image commands. That fixed mine.

Put it in fastboot mode and format (not erase) system, userdata and cache. Note any errors? Then use flash-all.bat with the latest image to (potentially) recover. Not being able to boot into Recovery mode is not a good sign.

I erased all partitions (except radio) and then tried to format all. Some failed formatting, but that did the trick.
