[Q] Failed OTA update help? - Nexus 4 Q&A, Help & Troubleshooting

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.
Can't say anything makes be panic not like nexus devices are hard to recover ☺

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

Can't root, did before though

Ok so I've done a bit of searching and asking on androidforums but nobody can figure out my an answer to my problem. Alright, first off originally the phone had android 1.5 but when sprint released the 2.1 update I did it. From there, I used regaws tutorial on rooting the official 2.1 release which worked great. Basically I was on a mission at this point, a mission to try out all the 2.1 based custom rims. I had been using the rom manager app for its ability to wipe and flash new roms without even rebooting to recovery. As you are probably aware, to do anything with rom manager, you have to have their clockwork mod recovery flashed, which is simple to do with this app. So one day I wiped and flashed a new rom, aloysius I think, and after it was trying to boot the new rom it gave me some error message and the installation failed. I think at this point I tried to restore my nandroid, which also didn't work, I'm guessing that you have to be using the same recovery you were using when you created the nandroid? No matter what I did from recovery I could not restore my nandroid, as a last ditch effort I did a factory wipe and then rebooted. I didn't think it would reboot at all, honestly I was way scared and thought that I had bricked the phone but after about 5 minutes it finished booting up. Now I don't understand why or how, but when it came to it was quite obvious, I was back at stock 2.1. I immediately look in the app tray for the superuser app and obviously it isn't there, I've been dealing with the phone as is for about a month. A couple of weeks ago I decided to get back to work, sat down at the computer and tried to root it again using the same exact method. After like 5 attempts I get the same problem, I get to the step where command prompt spells out "UNREVOKED" really big but I notice that instead of having a "$" like it shows in the picture I have a "#". At this point the guide instructs you to open the Superuser app on the app tray on the phone, sure enough, I don't have one. I have tried this probably like 7 times all with the same result. I've even tried to install that .6 update to patch whatever remnant of root access I have and go from there as I'm sure the fact I was rooted once and lost it has something to do with my failure. I've tried running RUU's many times as well and always wind up getting an error 171 USB connection error. I havent heard of anyone else having an issue like this. I'm not sure whether I posted this thread in the right place to really get help either so if this needs to be moved to development or whatever don't hesitate. I'd really appreciate anyone trying to figure this out as I am tired of running the slow stock rom but have exhausted virtually every option that I am aware of, PLEASE HELP ME!
I know everyone is probably still reading that book I posted, but once you get to the end lol please gimme some advice, i've tried everything and don't wanna live with the phone as is for the next year....
It's a little hard to read your original post, but I'll do my best to help. From the sound of it you may still have root.
I haven't had to root on stock 2.1 install, so I'm not familiar with the new method. If you get to a bash shell or terminal prompt that is a '#' rather than a '$', you still have root.
You said that you did a factory wipe on the phone. Did you RUU or did you simply wipe through recovery? Are you still able to get to the clockwork recovery?
If you can get back to your modded recovery, you're golden. I would STRONGLY recommend you flash the newest Amon_RA. http://forum.xda-developers.com/showpost.php?p=4898505&postcount=1
If you can get that far, you should just be able to wipe and flash a new ROM.
have you tried to update your sync/drivers on your computer lately?

Oh well I finally got it all figured out, had to rum the ruu twice back to back whole the phone was still frozen at the bootloader. From there I finally was able to re root it.

Running Rooted 3.2.1 to ICS? Do I unroot?

I'm running completely stock, no rom anything. Just flashed updates from users here to update me to the latest HC. I received the ICS update but pretty sure it won't work since I'm rooted and running CWM recovery. What do I need to do to install ICS? thanks

I'm running a rooted 3.2 stock by Timmy Dean.
I'm happy I didn't jump the gun when I Saw the update last night, because it seems I would have truly been screwed.
What I would like to know is if a rooted 3.2 can simply be unrooted. Seems this would the simplest thing to do.
Thanks in advance for any and all help.
Apparently the root doesn't matter. It will just be removed when we install the ota ICS. What worries me is recovery. Because it has to boot into a recovery to install ICS. I had CWM installed then flashed to stock by acer recovery tool in the play store. But when I manually boot into recovery, I get a exclamation point inside a triangle. What recovery are you guys running?

Yeah I think so as well. I flashed stock via the Acer recovery tool but I get nothing when I boot into recovery except what I stated above. I'm not sure if that's right or not.

I was happily running timmydean's rooted 3.2.1 based on the leaked OTA. The ICS upgrade came through and installed just fine. No loss of data and the programs I tried all worked. I was on stock 4.0.4 unrooted.
However, I'm now borked. I rebooted into recovery (Power, Vol -) to see about rooting via the backdoor I'd installed. I had thor's 1.7 Touch CWM recovery installed. I got some weird message that recovery was broken. (Don't recall the exact msg.)
After that, it hung on the "android" screen. Soft-bricked.
So I did a factory reset (Power, vol+, rock screen switch) and ended up back on 3.2.1. Now, the Settings > About > Check update results in the "Network coverage is currently poor. Please move to a location with better coverage to continue." message.
My WiFi is fine, speedtest.net reports a 20 Mbps download. All other apps function well. I'm pulling a DCHP address from my router.
I'm fairly sure this is a badly-worded error message from Acer and actually refers to server overload or some other issue on their end.
Also, installing the latest Acer Iconia Update preps the system for ICS. At one point, installing it allowed the update to proceed, but not to ICS. Uninstalling/reinstalling that update seemed to jog the system at one time.
So I tried wiping data/cache/dalvik and went back to stock 3.2. Same error message when updating. Wiped again and went back to stock 3.0.1. Same error message.
So I'm stuck and am going to give it a few days to see if Acer can sort out their upgrade path. If not, I will probably load CM9 or Thor's ICS ROM. (I do have a Nandroid, so I can get back to where I was pre-ICS.)
All in all, I'm very disappointed in Acer for borking my tablet.
________
Update: So now a day later, the "poor coverage" message was replaced by an "update available". Installed A500_7.014.03_com_gen1, after reboot, another update A500_7.014.15_com_gen1 installed. I am now on stock 3.2.1.
System update shows "Your device is up to date".
Will see what tomorrow brings, but this is certainly frustrating.

********************************************
Could you guys running the backdoor and still rooted please try this:
1) Try and capture the build no. of the update
2) See if the update will download BUT do not install yet
3) Go to /cache/fota/ and find the zip -
4) copy it to yr external sd
5) post back the build no.
thanks!!!
Procedure for manual install:
1/ rename the file as : update.zip
2/ place the file on the micro sd card
3/ turn off the tablet
4/ press the down volume key and the power button at the same time untill the tablets turns on
5/ the iconia will start the upgrade process by itself.
OR just redownload the update and it install
*********************************************
I had trouble when i reverted to stock in the weekend
and it was a bit of a process to get the OTA's to 3.2.1.
I did manage to hold "full root" but had to revert a couple of times
by putting stock recovery back and using backdoor .
I accidentally factory reset and everything went a bit pear shaped from there...oops!!
Im still waiting for the OTA ICS - getting network coverage error -one good thing
is my partners tab is only 5 days old and still pure factory,
her tab shows same error so at least we know its not root/backdoor problem
So yeah if u gonna take the OTA best to get rid of the backdoor unless you wanna play guinea pig for us all>>>>
dunno why we aint found one of those yet
I dont think you can cause too much of a problem where a "hard reset" pwr/vol -/rotation lock/ combo wont fix...you can then root from there.

hi 3d0rr!!
i think those of us with the backdoor should be meticulous if/when taking the OTA.
we shouldnt need to unroot and use stock recovery as the ota should get rid of that in the flash. But to ensure a stress free OTA it may pay to do it anyway.
i know you previously told me u were stock gen 1 - but is that from factory, just finished reading a very interesting post regarding the different 'gens' so i for one am sticking with factory build gen :just for the official OTA anyway:

Dibb_nz, I was stock gen 2. I don't wanna take OTA until be sure it's safe. Unless now I know that a hard factory reset may save my tab if something happen.
Can you tell us where did you read that post about 'gens'? I still a little confuse about that

BTW, the network coverage errors seems to be an Acer's error. First I received OTA and a day after that I see that error on my tab. And a couple of hours later I have OTA again. So, don't worry, you should get OTA asap

oh sounds promising, although I just read another post from someone across the ditch in OZ he reckoned acer said they were working on a patch for the problems theyre havin with the first update...who knows
now m8, sorry to confuse you, that wasnt my intention, but i try to make sure that i;m not suggesting things which may end with you or others borkin or brickin yr tab. Ive spent the last few days reading thousands of posts (just like everyone else) thankfully we are fortunate in being able to learn from the mistakes of others I know a bit more about ics than i did 3 days ago let me tell you, lol.
i just finished helpin out a fellow "timmy-ite" stuck with no way of getting in to apx mode to get un-borked...well didnt really help just a sounding board more than anything
he got himself up and running, used the apx tool in my sig, unlocked the bootloader, rooted, flashed custom recovery did a nand and is now running flexreaper - with the tools and knowledge he gained he now has the choice to go back to HC to get the OTA or not....he's one happy camper!!!
Have a read have a read thru the threadhere. ask him a question or two if you want - but dont get too hung up "maybe doing something wrong" you won't be the only person ever to experience that uhh-ohh sinking feeling when you know you shouldnt have just done whatever it was that u just did
Theres always someone round here who will help - usually cos they done the same silly lthings themselves - why ya think i'm always posting

timmydean's root method also allows you to install a backdoor to re-root after accepting an OTA. You have to manually install it during the rooting process, so you would know if you had it.

timmyDean How to root stock 3.2.1
Summary:
Version V4 is the same as V3 with the only difference being that there is a NEW backdoor script which has some additional features to protect root(#) from getting broken when you do an OTA. I also applied these to this flash image so you wouldn't have to add the additional protection yourself. V4 also has the drivers for XP included. However, when taking an OTA you should also install the backdoor for additional protection. However, you cannot leave the backdoor installed as it turns off sound. So having a little more protection just might save your root in case you take an OTA and forget to install the backdoor.

Well my friend, this worked to me... I hope this can help somebody else:
Original ROM: Acer A500 3.2.1 COM_GEN2 Rooted and with CWM using Timmy's method.
1) Go to play market and install Acer Recovery Installer.
2) Open Acer Recovery and verify with recovery do you have. In my case it was CWM recovery by thor2002ro 1.5
3) Install stock recovery. Make a backup of your old recovery when ask.
4) Factory reset: in my case, I made a backup of all my data and used Titanium to backup some apps. Then I harded reset my tab by turning it off and the combo pwd + vol(+) then lock-unlock switch 3 times until I saw "eraing user data" in the top-left corner.
5) turn on the tab and go to google play. Search for acer and install Update enhancement.
6) Go to settings-> about-> system update and aply the OTA update.
You will lost root, but everything should work fine.
To gain root access again, you can follow this thread -> http://forum.xda-developers.com/showthread.php?t=1546593
Now I have rooted stock ICS and I'm so happy
Hey great write up, will try this as soon as I'm off work. Anyway to confirm stock recovery is installed? Because I have done what you said(just the flash stock recovery part) an when I boot into recovery I just get a triangle an exclamation point. Not sure if thats right or not. But I will definitely give this a go since you were running exactly what I'm running now.

instead download blackthund3r's one-click-root,
google "ICS Root for Windows"
At step 3 - After you have backed up -
Copy the uid.txt file from the backup folder - this holds your cpu id -
you're probably gonna need it at sum stage

[Q] Bootloop on everything but Stock 4.2, tried everything, looked everywhere (hope)

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

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 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

18 year IT vet/Total newb to rooting/rom'ing tablets

I read how there are no stupid questions, well I'm about to test that I think. I'm a complete newblet to this sort of thing but I have an N7 2012 running like a dog on 5.1.1. So like many, many other posters here I want to make her fast again but would rather not rollback to 4.4.
So I found this: http://forum.xda-developers.com/nexus-7/development/rom-6-0-android-marshmallow-pure-aosp-t3226012
I wonder firstly, I didn't see a step on backing the current environment up in case of brickage. Is that something the author thinks anyone wanting to flash their unit should know how to do already?
And if so, are there any other steps that would be beneficial to do prior to the actual flashing that any experienced ROM alterer would do that I should as well?
Thanks guys!
I'm about to go down the same route.
I have TWRP recovery installed and am using it to backup the more or less stock setup. (except for TWRP recovery, custom kernel and SuperSU.)
I'm seeing that my backup will take 2.6 gigs though, which almost runs me out of SDCard space.
But since 5.1 is pretty much unusable I probably won't keep the backup long.
As long as your bootloader is unlocked, Nexus devices tend to be hard to brick (barring any N7 2012 specific issues.)
Consider upgrading to N7 2013 running stock Android 6.0. I have 2 for app testing and they are pretty darn nice, especially for the price. Can buy for less than $150 new now, and good bargains for used.
Thanks Mike, Question what guide did you follow to get yours rooted and the recovery stuff updated?

Wait, I figured it out. So I've got it rooted, then pushed Cyanogenmod recovery and rebooted and got into recovery mode. First off I tried loading Cyanogenmod 12.1 which worked well. It was snappy however I could not figure how to get gapps reinstalled. Thinking maybe another rom might already have google apps I then pushed 6.0.1_r10_Grouper-MM. Booted fine but still not gapps..
So I find a website that says to push the zip to /sdcard/ then apply update from sdcard in recovery mode. However now, I'm getting errors complaining about F2FS.
E:can't open /cache/recovery/last_log
E:unknown fs_type "f2fs" for /cache
Couldn't mount /sdcard
Installation aborted
Googles not been much help yet.

I've been doing this stuff for 5 years, so I usually don't need guides, just a few hints sometimes. CM recovery these days is something I try to avoid as it mostly works only with CM. I use TWRP and flash it with adb commands like:
adb reboot bootloader
fastboot flash recovery twrp-2.8.7.0-grouper.img
I ended up flashing this Marshmallow ROM because it seems to be the most popular at this time: http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172
And I'm happy with it so far.
Strange thing though is that I had to flash it 3 times to get it to flash without any error.
Then I had to flash the Benzo Gapps 2 times to get that on with no error. Result is working OK so far.
Damn Mike, I shoulda waited another hour before settling on mine. I tried that 6.0.1 i linked earlier in the thread about 4 times. Three times it applied successfully with 1 seeming to lockup during the new user setup. But I tried at least 4 different gapps that all didnt work. The usual results was Google Play Services have stopped. So because the day was nearing an end and I needed it last night to read I dropped back to the Cyanogenmod 12.1, changed the theme and tossed in Open Gapps Nano http://opengapps.org/?api=5.1&variant=nano
Wound up having to load play books, play services, gmail, and chrome individually.
But it's snappier than ever (so far). I'll end up re-trying 6 very soon but this time I'm trying the one you found.

I tried that MM ROM it worked fine for first week, then it started to act the same as it was on 5.1.1. I used Nexus Root Toolkit to flash my nexus to stock and then flash the rom with just few clicks

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.

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.
