[Q] Bootloop on everything but Stock 4.2, tried everything, looked everywhere (hope) - Nexus 4 Q&A, Help & Troubleshooting

I am not new to ROMs and flashing etc., but I am completely stumped on this one. I have looked everywhere I know to look (supposedly) but if you find some easily locatable solution that I have missed, please feel free to call me mean names and share the solution with me. Otherwise, this is what I have tried so far (I will start from the beginning):
First, the 4.3 OTA update bricked my phone. I hadn't rooted my N4 yet because it was an updrage from D1 (yes, big jump). I decided to root the phone and install a custom ROM. Can't be too hard right? Its a Nexus for crying out loud. WRONG. Well I rooted pretty easily, and installed my first custom ROM for N4. To install this ROM, I had to erase boot.img, system.img, and userdata.img and then flash each individually from the ROM zip file I downloaded. This worked! I was winging it and it worked out. However, from then on, EVERY ROM I tried to install ended up in a bootloop. I have wiped cache/data, dalvik cache, and even my own (c)ache before flashing new ROM. They all end in bootloop (never ending).
I am able to revert to stock 4.2 easily every time. However, any attempt at installing a custom ROM from there is void. Today I downloaded 4.4.2.tgz from google and ran flash-all.bat. Everything works great! Until I try to boot up; bootloop. I fastboot format this and fastboot erase that, then fastboot flash each .img individually. I fastboot flash new radio, new kernel, etc. etc. but still bootloop.
I really am clueless as to what I am doing wrong or how I screwed myself somewhere along the way, but I am humbly coming before my superiors and asking for help. Please offer me the simplest solution and call me dumb for not seeing it, I will hold you in my heart 4eva

This is why once I have my phone rooted, there's no turning back to stock.
Are you sure that you wiped system, along with everything else between adventures? (factory reset via recovery)

Ok, gonna make a suggestion, and it's totally on you if you want to take it, and of course I won't be held responsible. I have had a bootloop or two on my G2 (the original), I would get impatient and pull the battery. (wish the Nexus 4 had a removable battery) Without fail, that cured the bootloop. Just remember, that was a G2, not a Nexus 4.
Don't ask me why it worked because I have no clue.

I have cycled power a few times during the boot to no avail. I also just reverted back to stock 4.2 and then installed OTA 4.3 update hoping outcome would be different (definition of insanity according to Vaas). I don't know what to do. It's just not in me to run 4.2 forever

Constant Reboots, Hanging and Annoying Me

Okay, so first off, I'm literally about to light this fking thing on fire.
This damn phone has been the death of me. I have a Tbolt and Galaxy Tab, and NEITHER have been as much of a pain in my ass.
This seems impossible because since I got the phone, I've had nothing but problems.
1. Unlocked bootloader via fastboot. K, done.
2. Flash AmonRa Recovery (I did this before AND after using CWM recovery, having custom rom, etc, it never worked) Always sat in a loop at the google X with unlock symbol, or just reboots into normal (and yes, the MD5s are correct) 3. I've had the phone get into the rom both with SIM and without, and randomly reboot, from using anything from market, to file explorer, to hitting the lock screen.
Honestly, I'm tempted to just sell it again (since I bought it off ebay) and buy something different, though that's a pain to do, and I need it for a trip to europe in a week, so I would love to have a phone I'm not pissed off at. And yea, already got mad enough I threw it.
I've literally spent HOURS looking through Google results on all the issues. And have YET to make this lil pos stable enough for me to use like I do my tbolt. nice 100 battery pulls. Seriously. Heeelllpp on this, :-/

try
fastboot erase cache
fastboot erase userdata
fastboot erase system
and then flash via fastboot the AmonRa recovery again.
BTW, which ROM are you trying to flash? ICS or Gingerbread? And do you have Blackrose installed?

http://forum.xda-developers.com/showthread.php?t=872441 << Flashed this.
So far, I've knocked my network to 2g and it's been fine. though not really much of a fix. And I had cleared all of the above using CWM prior to the attempted flash. I'd rather not have to wipe everything again just to get AmonRa. I've wiped quite a few times. Though did get something about /sd-ext missing when erasing via CWM. Also, I tried erasing recovery, and got this: "erasing 'recovery'... FAILED (remote: not allowed)". Not sure if that matters. Just seems that flashing via Fastboot has failed everytime. I flashed CWM via fastboot and that failed too, I ended up getting it working via RomManager.
I had the same problem. After i dropped my phone on the floor everything worked fine

Done and done. Still have a problem with boot looping. Google X with vibration, then goes black and does it again, and it loops like that indefinitely. Though this isn't new, been since I unlocked it....POS.

First of all any ROM you find here for an update is going to have bugs. So have to prepared for reboots, and/or no boots.
On the other hand, you have to verify to see if you have any hardware issues. In order to do so, you have to flash to a stock ROM to see if the issue continues. If stock ROM is just fine, then its the custom ROM that is causing grief! So try another custom ROM, until the one that suits your needs.
my sugestion 2 u - use cm7.2. use 4ext touch recov, wipe all ur stuff, flash blackrose hboot with no repartitioning, flash cm7.2 rom, finally, stop b!tching!

Did it when it went back to stock. And Whoever said put it in the freezer, I did, and worked on it with AC on it, and it worked better . Though for some reason, never been able to flash recoveries via fastboot. Oh well. 4ext rocks.

Still having bootup problems
Okay, sorry to bring this back up, but I am still having an issue with the phone booting. If I get the phone on, it's fine, doesn't randomly turn off or anything. However, if I try to reboot, power off and power back on for any reason....it becomes a pain to get back up and running. I usually have to do a couple battery pulls before it comes back up. Does the same thing. Hits the X, vibrates once like it's gonna turn on. Then a few seconds to a min later, goes black, then flashes the x and vibrates once again. It loops like this until I pull the battery and try again. Sometimes it takes a couple times to work. Its not the ROM either, because this is the issue I had when I first got the phone and did fastboot oem unlock. It would hang on stock. It's done it on all 3 ROMs I've tried. I don't wanna say fully it's a CPU issue, because I don't have issues once it's on.
Any new idears?
PS. I tried CM7, and I didn't like it. Not a fan of AOSP ironically enough.
The Nexus One will give off 7 Vibrations to indicate a hardware issue, we will just have to wait and see

Am I Soft Bricked?

Here's the rundown:
I installed the Dark Paranoid Android (Grouper) ROM this morning. I flashed Gapps, and rebooted the device. No issues at that point, because I came from another ROM I did a clean install and got through the registration screens no problem. Once at the home screen, I remembered I had not flashed the Trinity (Grouper) kernel like I had planned, so I rebooted to recovery and flashed it.
That's when I ran into problems. Rebooted device and it stuck at the Google screen. Tried to bootloader into recovery, I still get stuck at the Google screen. Have tried to boot up both the recovery and into Android several times from bootloader, but I always get stuck at the Google screen. I guess my device didn't like the kernel, or somehow installing it damaged my recovery maybe?
Basically, I am asking if I am soft-bricked and have to restore factory and therefore wipe the device clean. Doing that would suck, but it's better than not having the device.
Also, I'd like to know if it's possible to flash stock through the Wugfresh toolkit without removing root. I just want to get back to stock so I can reinstall the ROM and try a different kernel.

Impossible with my device in the state I described.
Since the answers were fairly slow I already flashed factory image from Google with the toolkit. Issue was resolved, just will take a while to get everything put back on it.

Did you check the md5 on the kernel download? If there wasn't an md5 supplied, download the file a few times and compare the md5's between them for consistency. Could've been as simple as a bad download.

I did not check it. Maybe I will try it again later. Was able to right the problem by using the Nexus Toolkit to flash 4.1.2. Then I put DarkPA on it and started over. Not really the end of the world, just slightly time consuming.
I love the Trinity kernel on my phone. I want to use one for Nexus but I didn't see a stable one yet, all are in experimental phase.

N4 upgrade failed

Help me XDA, you're my only hope...
First, background: I bought my Nexus 4 over the internet, because it was never officially released in Belgium. I had to have the screen replaced, and let a 3rth party do it. Glass damage isn't covered by the warranty and it would mean sending my phone by international mail if i used the official warranty people. They told me that the also had to replace the proximity sensor.
My phone worked perfectly afterwards. Until I tried to install the automatic upgrade to 4.3.
First it stopped at the X-logo screen and became very hot. I contacted play support and did all the things they advised (including a factory reset, rebooting in safe mode), none of it works. I found someone with the same problem who managed to get past the X-screen by flashing back the 4.2.2 radio version. And that worked: the phone booted and the update started.
However, since that moment I got a lot of problems:
- random shutdowns
- random locking of the SIM card
- phone not starting unless plugged in charger.
Worst of all, reflashing stock images for 4.2 and 4.2.2 or AOKP does nothing to solve these problems. I also tried a new SIM card, and still nothing.
I'm at my wit's end now. Could there be a driver issue? Any other things I can try?
TIA
Possibly a driver issue and also reflashing does not help meaning that you need to flash an other kernel.

If your goal was to upgrade to stock 4.3, you can follow efrant's guide to flash the factory image at at http://forum.xda-developers.com/showthread.php?t=2010312&highlight=efrant. Just be sure to download the JWR66V image and use the updated file names when you flash since the file names in this guide are for the Android 4.2 image.

Well, I tried again. (For the 6th time this month) No different as before: it's been stuck on the X screen for 20 minutes now and getting warmer.
EDIT: I finally managed to get into the recovery menu. No idea why it wouldn't let me use volume up + power...
As suggested in the guide I deleted cache and a factory wipe.
My phone is still stuck at the X screen...
any other suggestions, anyone?

I never did that before: do I flash the kernel first or the Rom first? Are there any guides?
EDIT: I just read that Paranoid Android comes with the halfbreed kernel included. Is that the one you linked too?
Before jumping into the kernel thing (also because i wanted to be able to work with a device that can actually boot), I reinstalled the 4.2.2 factory image. It took about 5 minutes for the first shutdown to happen. *sigh*
And without plugging it in, it goes into a boot loop (going to x screen for a while, then restarting.) When I plug it in, it starts immediately, but shows the battery as empty. It was 63% when it shut itself down.
It's a clean install, I just don't understand...
Okay so, I'm assuming you have a custom recovery like TWRP. Open it and flash the newest boot loader and radio. Then flash Paranoid Android and GApps. Then try flashing Faux kernel and clearing cache/dalvik. If you still have problems, then I have no idea

Open up your phone to see the battery is securely checked and to see if all the components are okay. Then look do a full wipe of cache,dalvik,system,data,and sd (internal storage). Then use wugs toolkit to a upgrade on a clean flash. Double check to make sure you wipe everything!

Apparently, my battery had expanded so much that it was pushing at everything in the phone. I ordered a new one and put it in. In 4.2.2 I have no problems anymore with random shut-downs.
However, when I run the OTA upgrade, the phone stays on the X-logo screen. Just like last time. I expect that was why the battery got blown: the first time I ran the OTA, I did it at night and only checked the phone in the morning.
I fixed my N4 by reflashing an older radio (48, IIRC). I have no idea why the newest radio won't work...

Tried that before. I did some research and I guess this is relevant: http://www.androidpolice.com/2013/0...rops-on-some-nexus-4-handsets-fixes-in-sight/ Especially since I ordered my Nexus from the Netherlands.
I'll have to wait until that bug gets fixed until I can upgrade my radio.

[Q] Failed OTA update help?

I just got the OTA update to Android 4.4, and being eager to get it installed, hit the install button right away. I told a few people I was going to be a few minutes while installing the update... and tapped the button.
That was three hours ago, roughly.
I'm on a rooted nexus 4 with CWM Touch edition installed as a recovery. I don't know exactly what version right now but it was the latest when I installed it a few months ago.
The install launched CWM, and I waited as the loading bar filled. Right at the end it gave an error message - in a panic I didn't take note of what it was, hit the onscreen buttons and went through a window telling me I might have lost SU permissions - which I told it to fix. The startup animation (with four dots, the new 4.4 animation I guess?) started... and continued for more than five minutes.
I was still panicking and instantly launched back into CWM, downloaded a (I think correct, checked it multiple times, as on does...) update zip from the web, and flashed it via adb sideload. This gave me an "Error 7" and a failed install. I tried again, same result. Then gave up and hit the restart button in the hope that one of the attempts had indeed worked...
I now have a Nexus 4 sitting on my desk playing a nice dotty animation, and it's been doing that for fifteen minutes as of now. I'm intending to leave it as such hoping that it will actually turn on and it's just having a very long boot.
So, the question. Anyone have any ideas how to save my Nexus?
I'd rather like to end up with the data on the device intact (stupidly did not back up before installing and can't get any files off it until an install works) and possibly with Android KitKat running on it, as was the original aim of tonight, but if neither are possible, I'd at least like to end up with a functioning phone... just with any stock rom.
Thanks in advance.
P.S. I'm not new to flashing ROMs manually - my last phone was a ZTE Blade which never ran any ROM well, so I must have flashed on that phone at least ten times, including via ADB.
Ignore the above - I fixed the problem by using fast boot to flash the stock rom from developers.google.com/android/nexus/images ....
I feel really stupid now. But it worked perfectly. All I did was open the flash-all.sh and copy the commands out line by line, but removing the -w from the final command to dodge wiping the device. Anyone confident in Terminal or similar should be fine
Sorry for the thread being created but I really thought I couldn't fix this xD

Your post saved me from a complete wipe and reinstall, so thank you for sharing your fix. I had a very similar issue but my Status 7 appeared to be because of my previous root and the new install not being able change the permissions on some /system files.
Now I just need to re-enable root via the NRT.
at least you've learnt something. Ota updates will always fail if you have any cwm recovery installed. Not like it hasn't been discussed before. Guess you won't be making that mistake again.

To be fair, there are several posts around where people have simply updated their version of CWM and then reported the 4.4 upgrade has worked. I think I must have used the OTA Rootkeeper before as I don't recall these issues (other than losing root) during the 4.3 upgrades.
I'm in a similar boat.
My wife accepted the OTA update with TWRP installed and ended up in a boot loop. We didn't care about the data on the device, so thinking I could start from scratch, I did an Advanced Wipe of everything in TWRP. Now the phone has no OS on it.
I tried doing an adb sideload KitKatNexus4.tgz, but it gives me an error of a corrupted .zip every time.
I'm stumped.

Sideloading is only for flashable zip packages, not official factory images that required using fastboot. Use the guide links in my signature for instruction to flash factory image.
Or you can use sideload to flash flashable stock roms: http://forum.xda-developers.com/showthread.php?t=2527806
Unless your wife is really into flashing, I suggest just leaving it everything stock.

where did you find these posts? the only thing that I'm reading is people constantly saying "CWM will break OTA" or "you can't flash OTA with custom recovery" (this is clearly wrong)
I have the latest CWM recovery (6.0.4.3) and I don't want to lose it or flash stock recovery and CWM back. with 4.3 I remember that everything went good and I didn't have a lot of problems, the only thing I had to do was to unroot before flashing the OTA from CWM... but this time I'm reading a lot of conflicting posts so I'm a bit worried to try this by myself without some sort of feedback from any other user

It will softbrick the device, or atleast fail. I don't even have to try CWM, but with TWRP, if I make any changes to the /system partition it failed. I suggest you just flash a stock 4.4 rom: http://forum.xda-developers.com/showthread.php?t=2010887

Very specific bootloop issue

Heads up, this is a bit of reading
Ok so two nights ago, I was messing with the phone a little bit attempting to put Google Assistant on the phone. I had gotten a new cable from Amazon which enabled me to finally plug my 6P into the computer and my bootloader was already unlocked as I did so before but the issue was that I didn't have twrp yet on my phone. After I got it all set up with adb/fastboot etc. I tried to flash twrp. It didn't work, I kept getting stock recovery to come up so I ended up chalking it up for another day. As I was watching my beloved school lose in the Rose Bowl, I realized that the phone was rebooting. Not sure why but it just started doing it. After that, the phone turned on after rebooting for about 45 mins and it stood on for about 10 mins. After that, it went back to bootlooping and did so without getting to the android boot up screen all night.
Pissed, I decided to try to fix it myself but after I woke up, I found the recovery to be inaccessible through the bootloader which I could previously enter even through all of the bootlooping. After the bootlooping started, I couldn't flash a recovery so figuring it was the new cable, I switched to the older one. Well after doing that, I was able to flash the stock recovery and get adb working again. Using a guide, I flashed the newest factory image that was just released which is N4F26J (my phone was on the NMF26F update), and after a few bootloops, the phone turned on!
Ecstatic, I skipped past all the setup screens and went immediately to developer options and I activated usb debugging. Shortly after this, the bootlooping restarted and I wasn't able to get it to get back to the phone. Using the Wugs toolkit, I continued to use that to get the factory images on the Nexus and usually after I would use it to flash the ota, it would reboot a few times and get to the welcome screen where I could use the phone for about 5 mins. before it started bootlooping again. Fearing it was just Google's OTAs, I switched ROMs using twrp and adb to this ROM https://forum.xda-developers.com/nexus-6p/development/rom-debloated-prerooted-deoxeded-t3372600 (All Credit For The Rom Goes To Him), and after a few reboots, I got it up and running but after a few mins, the bootlooping started again. I noticed that when I use the toolkit to get into the twrp recovery, it constantly says in Red Letters about it not being able to mount storage.
If anyone please can help me figure this out, I would really really appreciate it. I can't send it to Huawei because it has a very slight crack on the screen and with me being a college student, I can't afford the $160 that they want to replace it. Somebody please give me any type of insight so I can try to fix this on my own. Please
btw before every flash, I followed all steps you should with wiping cache, dalvik, etc. Not sure if that would make a difference

Since you are familiar with NRT, I would start by running Advanced Utilities and fastboot FORMAT cache, system and userdata. Then go back to Flash Stock+ Unroot. Make sure you are set on at least NMF26F if Wug hasn't already updated to N4F26J yet. Flash stock. That should get you back up and running. There are other ADB options from the PC if this doesn't work for you.

Ok I'll give it a shot and let you know how it goes.

I think the problem you had with TWRP not sticking on Nougat is that you need to flash SuperSU after or the phone will revert back to stock recovery. Not that it helps with your boot loop issue.

Tried it and no dice. Hasn't stopped bootlooping for the past hour
I think you have the issue aoy of us are having which after three or four days I have not been able to fix. RMA with Huawei maybe the only way out of it.
Sorry man it doesn't look good.

Yeah it sucks simply because I've managed to get it from not booting to recovery to booting to the Rom but it just won't stick. This is hands down the worst experience I've ever had with a phone. The fact that Huawei wont replace it without that $160 is ridiculous to me because I've really done nothing wrong with it, it just konked out leaving me without a phone. Wow
Its probably google trying to force us into a pixel phone. If my 6p eats it, im done with Google phones. I love this phone. Its the best ive ever had. I'd definitely pay 160 for another if they could assure me no more bootloops. It sucks for people that can't afford it.

There well may well be a hardware problem with your device BUT I read your post again and I see a few possibilities. One is that you may have been using an unreliable data cable, and you didn't mention hash checking files before flashing. Second, it sounds like you had installed a factory image, and afterwards applied an OTA to the phone (and then a custom rom). Once you apply the full N4F26J image, there is no need use any OTA! Start with the latest image. Lastly, your data became encrypted when you booted the first time so you are getting mounting errors in TWRP. My advice would be to reformat again as above, manually download the full factory image N4F26J and use NRT to install it. NRT has not updated the toolkit yet, so you will have to d/l manually. NRT should hash check the file you downloaded. Use the bricked mode to Unroot+Flash Stock. You never mentioned running unencrypted, so I assume the default encryption is what you want. The idea is to attempt to get you back to stock with a device free from bootloops. If this doesn't work, then you'll need to use ADB.

Ok I'll give it a shot and let's see how this goes *fingers crossed*
UPDATE: Gave it a shot and it booted up to the welcome screen for about 2 mins and then started the bootloop all over again. Looks like the only option is to RMA the device at this point

Your phone is worth a lot more than 160.00 so it's probably best to RMA even if the charge seems unfair. You could always sell the RMA phone for a lot more than 160.00 if you've had enough of the 6P.

Sorry to hear that. Not ready to throw in the towel?
Have you tried doing a factory reset after the latest bootloop?
Any errors when formatting the 3 partitions, or during the flash process?
It could be looping for some reason during the initial encryption process which happens during first boot. I would try using a "no force-encrypt" modified boot.img before booting the first time to prevent the encryption process. If you prevent encryption, you may prevent the bootloop. You can find the boot.img on this forum, or use Wug's from the previous build, or even flash SU 2.79 to modify your boot.img.
If that doesn't work, you could try extracting files you need from the factory image, fastboot format and flash img files manually, including the modified boot.img.
