[SOLVED]Device stuck in bootloop - Nexus 4 Q&A, Help & Troubleshooting

Hey guys,
Regardless of my low post count, I'm not a noob when it comes to rooting\unlocking\flashing. With that being said, I've run into a few problems with my Nexus 4. I was making a nandroid backup of my most recent CM 10.1 nightly and decided to flash back to stock rooted in order to fix my bluetooth issues. When attempting to restore, I received an error stating that my MD5 sum didn't match. This happened to all but one of my backups and it would old restore part of my data before failing on the "working" backup. It would boot just fine, but it was basically a factory image and none of my downloaded applications restored execpt the icons. I realized that this image was pretty unstable so I took it one step further..... I decided to restore to factory stock by flashing the factory images from google (I snagged a copy before google pulled them). I ran the flash-all.bat and it restored everything with no issues.....but now it gets stuck on the nexus "X" during boot. I left it for about an hour and it's still on the "X". At this point, I decided to relock the bootloader and call google.
I realized that something is probably corrupt so I called Google and got an RMA but I won't get a new phone until LG makes more Nexus 4's (Nexi?, lol).
Does anyone have any ideas what could have happened? ANy ideas on how to fix this? I'd much rather fix this damn thing instead of going thru the RMA process.

Boot into stock recovery, clear cache and factory reset. You'll be up and running.

Maybe I'm more of a newb than I realize, lol.
How do I do that via stock rocovery? I just have the red triangle. I know how to do that in Team Win and CWM, but not in stock.

Boot into the bootloader by holding volume down and power.
Use the volume key to toggle to recovery and press power to select.
When you see the exclamation. Press volume up and power to open the recovery menu.
Then clear cache and factory reset.

I went ahead and unlocked the bootloader again and flashed CWM touch in the meantime. I cleared cache and reset. Same result. It's just hanging on boot.

No you need to do this in the stock recovery.

If I knew who you were......i'd kiss ya. Thanks man. It's fixed.
Now, just out of curiousity, why does that only work in stock recovery instead of a custom recovery?

Not entirely sure. The stock recovery wipe clears everything including data/media/
There also seems to be an issue with the bootloader not properly wiping the device. Hopefully they can fix the bug in a future update.
No kiss needed. Just a thanks and a virtual high five will do.

I see what you mean about not wiping everything.....after all the wiping and flashing, it still had my same custom wallpaper from my CM 10.1 ROM when it booted. Weird.
Thanks again.

That's not because of something not getting wiped.
Its because your wallpaper syncs to Google. It's auto downloaded and applied when signing in for the first time.

Correct me if I am wrong.......

Had my X for a week now. It is rooted and running DarkSlideBlur 4.2, I have several other ROM's I am wanting to try out......
If I understand what I have been reading right, I can use Nandroid Backups to return to ROM's I like, or is it better to reflash them?
Trying to avoid the whole setup process....
Thanks in advance

A nandroid would be the route to go. It restores your phone to the exact state it was when you backed it up. Every call text message everything will be as it was.
Nandroid all the way. Works every time

As already stated, a nandroid is a best bet. Just keep in mind if you do any updates (OTA) and the radio gets updated (i.e. 2.3.15 to 2.3.340) an old nandroid will brick your phone due to an older bootloader
Sent from my DROIDX using XDA App
Thanks guys! I thought that was the case, as I have been all over these forums "researching" for a couple months before I got the X!
Now off to research "Radio"?? (thats a new one to me)
But what if you mount your system and get stuck in the bootup. i cant even get to the recovery. i dont know what to do.
Nandroid always has your back. Something gets screwed and you are stuck in a boot loop, plug in the usb or charger, pull the battery, put it in and boot up. That will hijack back into Clockwork.
Always Wipe Data/Factory Reset, Wipe Cache/Advanced/Wipe Dalvik before you flash a new ROM and you "almost" always avoid a boot loop.
Sent from my DROIDX using XDA App
that is clockwork recovery, the stock recovery is accessed with a combination of hard keys which i am not sure which they are off the top of my head. in that you can wipe, but unfortunately no nandroid restore.
I tried every rom out there. The fastest most stable best battery life is stock. Deodexed stock. You can theme and font.

The hard keys are volume down and camera button if you wanted to know
Thats to get to the bootloader. Recovery is home and power and hold on until it comes up. To get into safe mode you hold power and the menu button

Updated SmoothROM and my Nexus 7 stopped working! Can't get back into recovery.

I have had my Nexus 7 with SmoothROM on it for a long time now, I use it here and there, but I noticed it acting kind of glitchy lately especially when using the keyboard. I got 2 notifications from GROUPER (i think thats the name of it...) saying I had an update to SmoothROM (v 4.2) and that google apps needed to be updated... I did the normal crap, wiped everything, flashed the new smoothrom, flashed on the google apps, but when I rebooted it just keeps popping up saying "Unfortunately, the process blah blah gapps has stopped", then when i press ok it says Unfortunately, Setup Wizard has stopped".... and when i press ok on that it just keeps popping back up... will NOT go away no matter what I try...
On top of this... I tried going to fastboot and putting it in recovery mode but then it just goes to the main boot screen that says Google with a lock at the bottom, and it is just stuck there...
So what would be the easiest course of action here? I can't get it into Recovery mode I don't think, although I forgot how to do it in the first place, I thought it had to do with sliding the lock somewhere at the boot screen but I have tried that and nothing seems to work...
ANY HELP WOULD BE GREATLY APPRECIATED!
Update: I managed to get into the settings and put USB Debugging on
so now it gets recognized by my computer and I can view and transfer files.... But I still can't get it into recovery mode so what should I do now lol?
Should I be looking for something like this " Google Nexus 7 Toolkit V3.2.0 " ?
Use wugs to restore to stock and start over
If you go back to smoothrom make sure you download it again might have been a bad download

When you power on your nexus press volume down and up and power button together for a couple of seconds. Your screen will go off and then "Google" will come up. Continue pressing and you will be in the boot loader menu. Go to recovery and install the ROM you want. (Can you get there?) Or else try to install it from your PC with cmd. Let me know if the first way works.

Same here, I dirty flashed it from stock instead of full wipe. Always do full wipe just in case.
Sent from my Nexus 7 using xda app-developers app
is the lock under the Google logo open or closed? if you installed a custom ROM, it should be open. if it is closed, the bootloader somehow got locked again.
however, i think the issue you are experiencing is related to gapps. you either have a bad download of gapps or flashed the wrong gapps (some roms require custom gapps). try the volume down+power thing to get to the bootloader, then go to recovery. if you can't, flash a recovery using fastboot or use one of those toolkits to flash a recovery. before you re-flash your ROM and gapps, i'd recommend verifying the MD5 sum, since that will tell you whether the downloaded file is good or not.
Sorry for the late reply guys but as it usually goes my ADHD got the best of me and before I came back to read this i ended up using that Google toolkit thing that I asked about and did what somebody said (option 9) to download and then install the stock ROM (but thank you!!) BUT in case anybody would like to know the lock was open and I could put it in fastboot but it wouldn't boot me into recovery. Hopefully anybody else updating smoothrom that ends up in my position will find this thread. I also suggest just downloaded the ROM and flashing it with the recovery that was my first time using that update ROM thing and it screwed up lol.
Again thanks a ton! Is there any new ROMs out there for the Nexus 7? Anything better than SmoothROM (or stock, lol)?

Rasbeanjelly with Franco kernel. I think it's the best out there.. I got 5k on quadrant with no overclock anywhere. Games play with no lag, it's very good

Maybe I'll try that... I'm gonna do quadrant right now I DLed it right after I got stock on but haven't tested it yet

I have seen a huge difference also in the overall speed of the system, very responsive and fast every second you should try it out

[Q] Completely Wiped, Fix?

I'm starting to really feel displeased about not having an external memory slot. My phone is entirely wiped. While in recovery, EVERYTHING was wiped. The custom recovery is still there, but when booting up the phone, it's stuck on the Google logo. Is there fix? When I plug it into my PC, I can't move filed to the phone for the recovery to flash a rom. I've tried using option 9 in the Toolkit, but it doesn't work.
Fast boot the stock image.

You can use adb sideload if your custom recovery supports it to push a stock ROM and jump off from that point. The stock images are still gone, for what ever reason, so there's no way right now to officially jump back to stock.

Yes, it does support it. Not sure how it works exatl. I guess I should finally install the SDK lol.
So what did you wipe in recovery to achieve this?
Someone will come along with the stock images if you keep bumping long enough.

Put your phone in to fastboot mode (hold down both volume buttons while you turn it on).
Stock 4.2.1 image; flash that with This.

Well I think I found the Stock 4.2.1 ROM deodexed, I was going to try and flash this in the meantime. I tried fastboot flash RomName.zip but it's a nogo. And I wipsed data/factory reset, cache partition, dilvik cache, and system and SD card.

Oh wow, it seems your stock rom was the key. I've tried that toolkit before, and it never worked with the stock rom it supplies, but for some reason I replaced it with the one you supplied and it seems to be going through now. Flashing as I type this, keeping fingers crossed.
EDIT: FIXED! YAY! I thanked you all for your input. I'm very greatful.
For future reference never wipe /system in recovery.

[Q] CM10.1.2 Bootloop

I was having a ton of problems with my Nexus 4, like i mean a TON
so I decided to just fix it and factory reset my phone. I rooted it with the nexus 4 tool kit and flashed TWRP. I found the CM10.1.2 zip and the 4.2.2 GAPPS. Flashed the ROM, then the GAPPS, then cleared both caches and Rebooted my phone. It is stuck at the spinning CM circle boot logo forever (I even left it on all night). I tried flashing CM10.1.0 with the 4.2.2 GAPPs same process and still in a boot loop. WTH is going on. I'm so frustrated. My phone was wiped clean and the only app I have is a file explorer besides the preinstalled Google apps.
Help.
I made a backup of when I freshly rooted my phone so I don't have to keep rooting when I enter recovery to get away from the boot loop
Before you flash the ROM did you do factory reset? Go into twrp do a factory reset then flash ROM and gapps then reboot it shouldn't take more then 5 mins for it to boot

I answered your post. The point of XDA is to share development work and learn how it works but if you're using a toolkit and not reading you'll never learn that's why you've had "a ton of problems" and don't know how to fix it

Sorry I never saw your reply. Thanks for replying. I did a factory reset from the settings menu NOT from within TWRP. And the toolkit is not to blame because I've used it plenty of times before and has not caused any problems. All it does is root my phone.
Umm you need to wipe within twrp before you flash. You're bootlooping because you only did a factory reset which only deletes cache and stuff. Wipe from within twrp and then flash

I wiped from within TWRP, rebooted and then my attenas were not working again. I could at least see the networks in my area but I could never connect on WiFi- it kept saying "Authenticating". It also said "No Service" for my 3G.
I booted back into TWRP and went into the advanced options for wiping and selected everything besides some "usb" thing and I think I deleted my OS -__- . I'm an idiot I should really not do what I don't know. I'm just going to flash stock ROM (4.2.2) with the Nexus 4 Tool Kit and see if things improve.
Thanks for your help.
In twrp if you're flashing a different always do the advanced wipe in order to clear the previous rom. Doing the basic wipe in twrp has the same effect of factory reset from earlier

[Q][HELP] Cannot start after switching to ART (stock ROM)

I have stock ROM, not unlocked, not rooted.
Have just OTA updated to Android 4.4. It was successful.
After that I tried to switch runtime to ART. The first reboot was successful. But runtime is still Dalvik. So I tried to switch to ART again.
Now it cannot bootup. It stucked with the four-color-circle.
I tried fastboot mode. But still cannot start.
Is it totally bricked? What can I do next? I think I haven't enabled USB debugging...
You can get into the stock recovery and try clearing cache or if that fails then try factory reset.
Sent from my Nexus 5 using xda app-developers app
Factory reset will wipe all your data, wipe cache will clear the apps cache so hopefully it will it fix it. Instruction to get into recovery here.

I go to the recovery mode, it says "No command".
With stock recovery once you see the android with the red exclamation you need to press power and volume up at the same time to see the commands. It's a little tricky and it might take a few tries but it does work
