Hello everyone!
I tried to restore the stock image using Nexus 4 Tool Kit (both the original one and the Wug's one), and everytime I tried, the script stucked at "writing system".
I manually flashed system and userdata images with Wug's tool kit and everything went well but I only have 5Gb memory instead of 16.
Does anyone know why?

[HOW-TO] Fix internal storage if 16GB now shows 8GB
Sent from my Nexus 4
OP...
In future, don't use a toolkit. Do it yourself
I'm having a similar problem to the OP - I'm trying to do a factory restore, and am unable to flash the "system" image. I can't boot, recovery mode won't work anymore (I get a red warning sign instead)...
I think all of this has to do with me being naieve and following a youtube video instead of the CM wiki to install CM 10.1.

When going into recovery the warning sign is the splash screen for stock recovery. This likely means that you have not yet flashed a custom recovery yet, which is necessary to flash CM. First read this guide to unlock the bootloader (if you havent already), then flash a custom recovery (preferably TWRP). After you have installed the recovery, download CM as well as the latest gapps package and place them somewhere on your internal sd. Boot into recovery and go to the wipe menu, then swipe to factory reset. Finally flash the rom and gapps, and then reboot.

if you are doing a factory restore and DONT need to flash everything individually than don't. yes its good to know how to do it manually but if your flashing everything back just use the script that google provides.
reboot to bootloader/fastboot and run the flash-all.bat file and its all done for you. no toolkits no playing with commands that you dont know properly etc.
if you dont know how to do it right pick the least complicated option.

I am using the .bat file... I've also tried the toolkit, and both appear to use the same basic procedure, and they stop at "writing system" no matter what.
Does anyone happen to know how the .bat file and toolkit get access to the phone? ...because I can't see it in adb (I'm guessing it's because I can't boot the phone.) However I can get into fastboot and recovery modes on the device.
I cannot get the device (nexus 4) to boot or connect in ADB mode to my computer. What can I do??
UPDATE - PROBLEM FIXED
I un-bricked my phone
SOLUTION this is what worked for me, your mileage may vary
Install ADB drivers, etc. from Android SDK (google how to do this)
Flash custom recovery (can be done easily with Nexus 4 Toolkit here on XDA) - I used TWRP Touch Recovery.
Once that is done, shut the phone off completely and boot into Fastboot (hold volume down and power)
Use volume keys to select Recovery Mode, then hit Power
In recovery mode:
Wipe > Advanced Wipe > Check off the box beside "System" > Swipe to Wipe
Go back to recovery mode main screen:
Wipe > Format Data > Follow the instructions on the screen
I think this step is what did it. When having problems with partitions, just format everything and start over
Now we should be able to write to the System partition, meaning you can flash a ROM and get your phone to boot again.
Follow the rest of these instructions to quickly flash the stock Android image from Google onto your phone.
Go back to recovery mode main screen, once again:
Reboot > Bootloader > Follow any additional instructions it gives you
Download Google Nexus 4 factory stock image "occam" (Google it)
When that is downloaded, open it with 7zip. Inside there are some files, one of which is called image-occam-jdq39.zip. Inside are some images - unzip those as well. You'll need the system.img file in a bit...
Using Wug's Nexus Root Toolkit (Google it - install it on your Windows PC):
Open the program
Launch advanced utilities
Hit the System button to permanently flash to System partition. Hit "ok" on the window that pops up.
Find the system.img file I mentioned back on step 10 and select that, when prompted, and open it.
If all went well, your device will now boot into the stock Android ROM.

I too am stuck at writing system. I"m not sure what you mean when you said "run flash-all.bat". Where do I get that?
Thanks.

The system takes awhile to write, how long have you guys wait before you say its "stuck"?

About 20-25 minutes.
Yea, that's way too long.

Stuck, but working
I was flashing the 4.3 image using the included flash-all.bat (but I edited it to remove -w parameter so that it wouldn't wipe my data).
In the 'writing system' step, the command window got stuck. In the phone screen, at the bottom, it said 'writing' for a while and then that also went away. I waited for ~40 min, and still the command window was at 'writing system', so I closed the command window, and booted my phone by selecting start from the bootloader.
And voila! It worked. Booted in under a minute, the flash was a success, I got JB 4.3 without losing any of my data.
Lost my root and custom recovery though. But I knew that would happen. Gonna try SuperSu for 4.3 now, after flashing TWRP.
Had the same problem, tried everything! With my tiny powers, but it kept stucking at "writing system" . I thought that I bricked the device, so for the last hope, I installed WugFresh's Nexus Toolkit and did a Fast Stock + unroot. It Installed everything flawlessly! I'm gonna donate to that guy! He's a godsend savior.
Hello,
I saw that the OTA update to Lollipop was available on my phone today, so I went ahead and let it download. Upon completion of the download, it restarted and applied patches, then restarted again and has been stuck in boot loop for about an hour. After reading several other threads on how to try to reset the phone, I'm stuck. When I try power + volume up or down, the LED status indicator flashes red and I never get to any kind of other screen. Am I completely screwed? I previously had stock 4.4.2 with no modifications.
Finally was able to get to the bootloader menu. Apparently having the phone plugged into the charger was preventing me from getting there for some reason. I ended up having to wipe the phone to get it to boot
so you can get into clock recovery right? download nexus 4 toolkit..that might save your phone. I suggest you to unroot and flash everything to stock and then unlock again and start everything from scratch. good luck.
Similar issue on an OTA upgrade to an unrooted N4. It's stuck on the Lollipol boot screen with the rotating Circle thingies.
I can get to the Android System Recovery but there's no CWM or TWRP on my N4. I'm guessing a factory reset will fix it but is there a way to preserve my pics/files on the phone before doing so?

I guess TWRP Recovery has option to enable MTP and you can access the internal SD card by connecting mobile with computer using usb cable.

Flash TWRP Recovery using fastboot.
1. If you have otg y cable, connect it and use file manager to copy all the files.
2. OTG method is failed then select “Mount”, then select only “Data” and connect your Nexus 4 to your computer and Enable MTP in TWRP. now you can use adb pull and push commands.
I ended up going the factory reset route, which wasn't really a bad thing. My photos had been backed up in dropbox and the play store remembered all the apps and were able to reload them. The only things I really had to do was reload some music onto the phone and re-enter passwords for apps.
Same story here: sideloaded the OTA zip file, then had bootloop. Tried a few approaches, but none worked. In the end only wiping the data was the solution for me. Lost some userdata in a few important Apps...
I went through this yesterday. The only way to get it to boot is a Factory Reset from Recovery. It works like magic, but sucks you lose the data.
Got the OTA yesterday and also got a bootloop(stuck in boot screen animation). I couldnt afford losing my photos/videos as i had no backup , so i figured out a super easy to get it to boot without wiping data .
I was unrooted with stock recovery running stock 4.4.2, bootloader was unlocked. I flashed CWM recovery through fastboot and wiped chache+ Dalvik from there then simply rebooted the phone .
I had already tried wiping cache from the stock Android recovery,needless to say that didnt work for me.
If anyone else is having the same problem please try the method above and report back, cheers!
I post this on Google Product Forum 2 days ago. Hope it helps

(updated 29/11/2014)[not perfect but it is a SOLUTION]
The idea of this is to downgrade your nexus 4 without wiping your data, which means stuff you will need includes:
1. adb and fastboot on your computer (I am using mac but you can find it on windows as well. There are tones of website and forums telling you the latest method of getting it onto your computer)
2. factory image of nexus 4(I use 4.4.4, since that's what it was. I don't have the time and energy to try to do the same thing with lollipop. you can try can leave a comment).
update: do NOT try to flash 5.0 rom using this method. You will be stuck at boot loop again
3. usb cable
4. nexus 4 with unlocked bootloader(the process of unlocking bootloader will wipe your device)
5. computer
steps
1. unzip the factory image (something.tgz)
2. for me, after unzipping the .tgz, I still find another .zip inside. unzip that too.
3. hold vol+, vol-, and power button simultaneously to enter fastboot mode
4. open terminal(mac)(it would probably be cmd for windows)
5. connect your nexus 4(in fastboot)
6. to make sure it connect successfully, type "fastboot devices". if something like "005040c0d54bb291 fastboot" appears, you are good. Otherwise, try reconnect your device/boot to fastboot again/use another usb cable
7.now we need to tell the terminal to navigate to the location of the unzipped factory image. to do that, i suggest you put the unzipped folder to somewhere easy to find, like desktop. these are some commands to help you navigate:
"ls" allows you to look at whats inside the current directory of the terminal. For example, this is the output after typing "ls" for me:
some folder Photos
nexus4image.tgz how many folders do you have
5.zip occam-ktu84p
more folder occam-ktu84p.zip
after knowing where you are, use "cd" (below) to go to your folder
"cd" means change directory. For example. "cd Photos" will brings me to the "Photos" folder. And then if I type ls, I will see a whole bunch of photos in my photos. If you go to the wrong folder, type "cd ..", and it will bring you back to the previous folder.
8. flash bootloader.
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash bootloader bootloader-mako-makoz30d.img
9. reboot bootloader. just copy and paste
fastboot reboot-bootloader
10. flash radio
enter the following command, BUT REMEMBER TO CHANGE THE NAME TO FIT YOURS(DIFFERENT VERSIONS HAVE SLIGHTLY DIFFERENT FILE NAME AT THE END(type ls first to help you type the correct name)
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.03.img
11. reboot bootloader. just copy and paste
fastboot reboot-bootloader
12. flash system
system.img is located inside the zip, use ls to help you navigate. This steps takes the longest time, total time on this step is 87 seconds while the others are less then 1 second
fastboot flash system system.img
13. flash boot
boot.img is located inside the zip, use ls to help you navigate.
fastboot flash boot boot.img
14. flash recovery
fastboot.img is located inside the zip, use ls to help you navigate.
fastboot flash recovery recovery.img
15. format cache(not the memory, so everything should be fine)
fastboot format cache
16. reboot and wait
this will reboot your device. You probably have to wait for a while to initialise all the apps. after than you are good to go!
fastboot reboot

I decided to go to Android 5.0.1 from CM10.2 on my Nexus 4. I guess I did not think it though that well and relied on some crappy guides too much.
I have CWM Recovery 6.4.3 installed, so I thought I just place the factory image on the phone and install it via CWM. So:
1) Copied occam-....tgz on the phone;
2) Rebooted into CWM recovery;
3) Did wipe cache/format system/wipe dalvik;
4) Went to install .zip menu... and figured out that the file is no longer on my phone.
I thought OK, I do it via ADB and cable, so installed ADB, drivers etc. and connected my phone to my computer. However, adb does not see it most of the time (when at logo, bootloader, recovery) and only once adb managed to see it (*some number* device unauthorized) while the phone was at Google logo. And I realized I forgot to set up the USB debug option. What are my options now? I can go into CWM recovery, but ADB does not see the device, as I forgot to set up recovery before flashing. Help, please?
The computer sees the phone as MLP, but I still cannot see its storage in Explorer, so I cannot copy the .zip file.
Update
I managed to make adb recognize the phone, but consistently says that it is not authorized, which makes sense. And there is not way I can mount it as an external storage .
first of all, you have a serious lack of knowledge. not activating USB debugging in android settings has no effect whatsoever on ADB usage ability when you are in recovery mode. Secondly, installing factory images is not done through recovery (the downloaded factory image zip is not even flashable so it would work not in recovery), as factory images also contain RADIO and BOOTLOADER images that are flashable through fastboot (not the recovery). The only thing from factory image that you could flash via recovery is a zip file named - in case of 5.0.1 factory image - image-occam-lrx22c.zip (you can find it if you unpack the downloaded factory image on your PC). And this zip file is a classic ROM (system,userdata,boot,cache,recovery partitions). However, even if you were to flash the correct zip (rather than the zip containing entire factory image complete with ROM, RADIO and BOOTLOADER) Android 5.0 (or 5.0.1) comes with updated RADIO (maybe bootloader aswell, i did not check), so you are supposed to update that aswell prior to switching to 5.0/5.0.1
now here is what you should do:
1. download 5.0.1 factory image from gooogle
2. make sure you have ADB and drivers for Nexus4 correctly set up (in order to check wheter it works go see point 3 of this instruction set)
3. boot to fastboot mode (vol down+power) and check if 'fastboot devices' gives you back device id (you should open command prompt in platform-tools folder, where both adb.exe and fastboot.exe are present)
4. proceed with this instruction, start at step 8 http://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/ (in step 11, name of zip file is the one that is INSIDE downloaded factiory image file (image-occam-lrx22c.zip) and you either do the single zip flash or flashing each of .img files separately (system,boot,userdata,cache,recovery)
ps. 1st android 5.0.1 boot after flashing will take up to 15 minutes. (it took 10 in my case)
Update 2
Thanks dzumagos! Sure, I do not claim to be a specialist by any means. I managed to successfully install Cyanogenmod many times, so thought I would give this one a go as well.
I read your post after I fixed the issue. Basically I did exactly what you suggested, but following another guide and it worked fine, also took it around 15 minutes to load the first time. I noticed I do miss a few tricks from Cyanogenmod
[INFO] How to sideload 5.1.1 (LYZ28E), & maintain no encryption - no wipe required
Simplified procedures with LMY47M / LYZ28E now available as a factory image.
Hopefully this isn't blatantly obvious to everyone, it is a little different than the normal sideload procedure. Thought it might be useful to some who want to load 5.1.1 (and get Wifi calling with T-Mobile!) and not be forced to encrypt.
Requirements:
1. I'm assuming you have adb/fastboot working on your computer / connecting to your device and you understand a little bit about using adb / fastboot with an android phone.
2. Your phone cannot be encrypted, if you're encrypted already - this will not un-encrypt your data - you need to turn off forced encryption and format the "userdata" partition to disable the encryption.
3. You need to have an unlocked bootloader for this to work of course.
How to follow this procedure:
1. If you're on LMY47M (T-Mobile) and unencrypted, you can follow option 2, starting with Step 3 - only a small ~150MB download required.
2. If you're on anything other than LMY47M, you should use option 1 unless you have a desire to flash LMY47M and sideload LYZ28E.
I didn't do much here - except spent a bunch of time writing the procedure.

——————————————————————————————————
OPTION 1 - Easy Method - Flash the LYZ28E factory image directly:
1. Download hlxanthus's NO FORCE ENCRYPT mod and put it onto your phone so you can flash it later (in /storage/sdcard0) - https://basketbuild.com/filedl/devs...u/misc/NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip
2. Download LYZ28E for Nexus 6 ( https://dl.google.com/dl/android/aosp/shamu-lyz28e-factory-b542b88a.tgz ) and extract the files, there is a zip file you want to extract that too.
Boot to the bootloader ("adb reboot bootloader") and fastboot flash the boot, cache, recovery, radio and system:
Code:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img (OPTIONAL - If you have TWRP or another alternative recovery you can skip this step)
fastboot flash radio radio-shamu-<variable>.img
fastboot flash system system.img
3. Restart the Bootloader, and flash TWRP, found here: ( https://twrp.me/devices/motorolanexus6.html )
Code:
fastboot flash recovery twrp-2.8.6.0-shamu.img
4. Restart the Bootloader again and then go to Recovery (TWRP). Now flash NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip through TWRP, and flash SuperSU if you want root and whatever other zips you want to flash (Xposed, etc)
After flashing the NO FORCE ENCRYPT mod, reboot and you should be running 5.1.1 with all of your data and with your userdata partition intact and unencrypted!
———————————————————————————————————————————————————
OPTION 2 - SIDELOAD Method (Makes sense if you’re already on LMY47M):
1. Download hlxanthus's NO FORCE ENCRYPT mod and put it onto your phone so you can flash it later (in /storage/sdcard0) - https://basketbuild.com/filedl/devs...u/misc/NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip
2. Follow the normal procedure, if you're already on LMY47M you can skip to step 3. Download LMY47M for Nexus 6 ( https://dl.google.com/dl/android/aosp/shamu-lmy47m-factory-5228e84a.tgz ) and extract the files, there is a zip file you want to extract that too.
Boot to the bootloader ("adb reboot bootloader") and fastboot flash the boot, cache, recovery, radio and system:
Code:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash radio radio-shamu-<variable>.img
fastboot flash system system.img
3. Now flash TWRP, found here: ( https://twrp.me/devices/motorolanexus6.html )
Code:
fastboot flash recovery twrp-2.8.6.0-shamu.img
4. Restart the bootloader, and enter recovery mode (TWRP). Once in TWRP, go to Advanced -> ADB Sideload. You may need to unplug/plug in the USB cable to your computer again.
Download my version of LYZ28E from here: https://www.androidfilehost.com/?fid=23991606952609905
Note: I modified this version to work with TWRP, it will not work with the stock recovery (because I modified it, the signature on the file is now invalid). The only thing I changed was I edited the updater-script to remove the release keys check which seems to fail on the stock recovery and doesn't work right with TWRP).
Code:
adb sideload f69096766706fab3c721163f02aad9073a989d00.unsigned-shamu-LYZ28E-from-LMY47M-fullradio-fix-superblock-use-TWRP.zip
5. After it finishes, do not reboot yet. Go back and I recommend rebooting to recovery again. Now flash NO_FORCE_ENCRYPT_shamu_v1.0-signed.zip through TWRP, and flash SuperSU if you want root and whatever other zips you want to flash (Xposed, etc)
After flashing the NO FORCE ENCRYPT mod, reboot and you should be running 5.1.1 with all of your data and with your userdata partition intact and unencrypted!
why would you think that you have to be encrypted to push anything to recovery??? plus sideload is only one method to do it, the other is adb push. and if you use twrp recovery, you don't need any of those method's, as you can just move files over to twrp via your usb.

Sorry if I gave the impression you need to be encrypted to push to recovery, that wasn't my intent. Where did I give that impression? I can try to fix it in my original post. At no point in this procedure will your phone be encrypted - there will be times that the kernel will have the force encryption option turned ON in the fstab but you never will boot the phone when that is the case (like right after LRX22C is loaded, after LYM47M is sideloaded, and after you flash the stock boot.img for LYM47M - but you are not booting in any of these cases - not before you install a no forced encryption kernel)
adb push requires the phone is booted right? I wasn't able to get adb push to work in recovery.
I also didn't know TWRP allowed you to copy data over to your phone via USB, I know CWM recovery can do it - but that was a feature missing from TWRP - maybe they added it, I didn't check. You can do an adb push with TWRP, but what in my procedure would you change to use the adb push method in TWRP versus whatever I put in there? The only thing I can think of is asking you to put the mod file on the phone in the beginning.

"So I just figured out how to sideload LYZ28E on my Nexus 6 without enabling forced encryption. "
actually adb push is very easy.. boot unto recovery, type adb push filename.zip, then it pushes to your phone and is listed in the main storage filesystem. id say its nearly identical to adb sideload.

Sorry maybe that first sentence is poorly worded. What I meant was, I figured out how to get LYZ28E onto my phone and disable the forced encryption on the OS too. The process wasn't as straightforward because the 2nd sideload wouldn't work correctly without booting into the OS first. After that, I couldn't get the LYZ28E image to sideload on stock recovery or TWRP without errors - but I was able to modify the LYZ28E OTA file so it would load with TWRP, and then I was able to load the no encrypt mod and supersu and get the phone working the way I wanted again.
Are you saying it would be easier if I push the zip file to the phone and install using TWRP as a zip file instead of trying to sideload it?
Step 3: "Hold down the Power and Volume Up button (may need to do it a few times) to get to the Recovery menu".
Actually, the correct key combination is: Hold power, then (while holding power button) press and release volume up.
Works first time, every time.

Shouldn't this step be
Code:
adb sideload f69096766706fab3c721163f02aad9073a989d00.unsigned-shamu-LYZ28E-from-LMY47M-fullradio-fix-superblock-use-TWRP.zip
instead of fastboot flash?
So if your starting out with 47E, your rooted and have TWRP ..... would you use adb sideload in TWRP or you issue the command from the PC?

This is where I was, LMY47E, rooted, unencrypted and with TWRP. I followed the entire procedure - went back to LRX22C using fastboot, then sideloaded LMY47M (T-Mobile version) - then flashed the no force encrypt boot.img - booted, after it finished booting, rebooted to the bootloader and so on ...
When you go to LRX22C you flash back to the stock recovery. So you need to boot into the stock recovery, pick "apply update from adb" and then run the adb sideload command from the PC.
Cheers for this.. just what I was looking for. I'm at work so I only scanned this quickly, but any major change in the directions from what you've posted going from an unencrypted LMY47D?
With the factory images being posted, I just did the following:
Flashed the factory images
While still in bootloader, flashed TWRP
Rebooted into TWRP
Pushed SuperSU and the No_Force_encrypt to the /sdcard/ partition
Installed via TWRP
Profit.

For LMY47D you need to get to LMY47M first, so you would follow the entire procedure, downgrade to LRX22C and then sideload LMY47M and so on.
Heavily updated the procedure since LMY47M and LYZ28E factory images are now available directly from Google.
Should be a lot easier and more straight forward now!
I just recently have this Nexus 6 and came from an LG G2. I went through the process of unlocking the phone and installing rooted LMY47D which meant 2 factory resets in a short period.
I'm now on 5.1 and would like to get rid of the memory leak which this build apparently has.
The title mentions "maintain no encryption".
I never found the time to find out about Lollipop. The title implies that encryption is mandatory on 5.1.1
Is this so?
I merely want the latest upgrade to 5.1.1 and don't want to enforce encryption on my data (Google already knows everything about me) is this the way to achieve this?
I am correct in thinking that I will not get an OTA offered anymore?
Boot loader and radio only...
So if I understand the instructions correctly, if you are still encrypted but rooted, from any Lollipop installation, fast boot flash the factory images... then flash TWRP ... root and done right? Then I have another question... the kernel I am running EX 1.07 along with Flar's app is running perfect for me.... any dangers in just flashing the boot loader and radio? I would like to wait on the system part until the kernel has been updated.....
Also, if I needed to do a restore, if I only flash the boot loader and radio have I pooched being able to go backwards to a nand backup?
FYI, step 3 in option one should read:
fastboot flash recovery twrp-2.8.6.0-shamu.img
vs
fastboot flash twrp-2.8.6.0-shamu.img

Starting with Android Lollipop (5.0) and newer - at least on the Nexus 6 - encryption is turned on by default for the userdata partition.
You would - if you wanted to - backup all of the data on your userdata partition (e.g. Any pictures you've taken with the phone, etc - all of the data basically that shows up when you plug your phone into your computer).
Then you need to be running an OS that doesn't force encryption (for example if you follow my instructions) - this would also get you running 5.1.1.
After that you need to format your userdata - it wouldn't be encrypted at that point, and then copy your data back if you want to.
If you don't care about encryption, you can simply flash the factory 5.1.1 image following my instructions and skip the TWRP parts.
Hello,
I'm hoping to get some help with my Nexus Player that has been down since N Preview 1.
To preface this, yes I've been rooting and romming for years, I would not consider myself a "newb" in the slightest but no matter what I try, I can't get this working.
I enrolled in the dev program and did the OTA for Preview 1. It got pretty laggy so I went into settings and just had it reboot. Ever since I rebooted it, it's been stuck in a boot loop.
I tried the following things in this order using stock recovery only because for some reason I can't get it to flash a custom recovery (and yes, bootloader is unlocked):
1. Wipe cache via stock recovery
2. Factory reset
3. Flash factory marshmallow image via bootloader
4. Manually flash each partition separately
5. Wipe individual partitions and then reflash their respective images
6. Nexus Root Toolkit automated "Back to stock" feature
7. Flash Google's OTA Zip file
8. Ask for help on XDA.
Regardless of what I do or how I do it, I get errors in the command prompt when flashing via fastboot and when I try to do anything via stock recovery I get the error that you see in the video.
Any help would really be appreciated.

Here's a follow up video that shows the errors that I'm getting in detail.
Thanks again for your help.
Is there really anyone that can help me?
Which method did you use to try to flash a custom recovery? Nexus Root Toolkit fails for that function but I have had success when I use the fastboot flash recovery command manually. If you manage to get TWRP 3.0.2-0 to flash and reboot in to it, you can try flashing the latest system.img file from the recovery mode's GUI (after you've saved the file on to an external storage device).
Thanks. I'm know I tried to flash twrp manually at some point but I'll give it a shot. I may also try the "Boot into Custom Recovery" that a lot of the toolkits offer. Although, I'm pretty sure I've tried that in the past too.
I'll update with results.

Alright,
I tried flashing via fastboot and the command prompt completes and says it's finished but when I reboot to recovery I just get the standard Android recovery.
I tried locking the bootloader so I could then unlock it and force a factory reset but it wouldn't even allow me to lock it.
Again the command prompt made it seem like it worked just fine but it didn't actually do it.
Try the fastboot boot recovery (filename) command as an alternative. I suggest not using the current version of Nexus Root Toolkit for anything recovery-related when it comes to the Nexus Player. In other words, use the AndroidSDKSlim package and try things manually with the command prompt.
Okay. I'll give it a shot.

That command won't even work for me.
Fastboot boot recovery [file path to twrp]

According to the attached picture, the actual command may be slightly different. Based on your most recent pictures, however, it seems that you may not be going through the manual process as I would expect. What I mean, for example, is:
1) Download AndroidSDKSlim.zip and extract it to your C: drive. Copy the twrp.img file to the platform-tools folder.
2) Use the search function of Windows 10 to load cmd.exe.
3) Navigate to the platform-tools directory by using the cd (directory path) command.
4) After you've navigated in to the platform-tools folder, try the recovery flash command I suggested earlier or the one shown in the attached screenshot.

I've uploaded what I did to YouTube.
Okay, I watched your video. The picture I attached in my previous post says to type in fastboot boot twrp.img whereas you still left in the word recovery before the file name.

Alright! I tried it and instead of rebooting into a recovery, it just reboots the bootloader.
Which recovery does it boot in to if you then use the bottom button to access recovery mode immediately after this step?
---------- Post added at 04:54 PM ---------- Previous post was at 04:39 PM ----------
If that still doesn't let you in to the custom recovery, I'll quote WugFresh on something else you can try with his Nexus Root Toolkit (if you haven't already done so).
2. The toolkit can be used to flash these factory packages, but if you are experiencing "system.img" not found errors, due to a possible issue with google's package - simply enable FORCE FLASH MODE, which is in the toolkits main options menu (just make sure you have selected the correct device before flashing).
3. If you experienced any weirdness or you device is messed up, simply use "Flash Stock + Unroot' with "Softbrick mode" to restore your device back to stock (you can also use this to flash Lollipop directly - which, as I just mentioned - may be good to enable force flash mode first).
See next post.

I get the stock Android recovery if I reboot into recovery immediately after that step using the hardware button.
Also, I've tried the force flash through NRT, I've tried manually flashing each image via NRT (and via command prompt via fastboot). It seems to be able to write every single partition EXCEPT the system partition, and clearly it's having issues getting a recovery to stick too.
It's unfortunate that none of these troubleshooting ideas has worked for you. If a preview image of Android N caused this, I'm starting to think that a factory image of a stable Android N release may be necessary to fully flash the device.

I don't think that will work. Regardless of what image I'm flashing that shouldn't change the fact that I can't write to the system partition at all or that a recovery won't stick.

So I've waited all this time to flash the stable Nougat build on this Nexus Player and I'm still seeing all the same errors.
When I boot into stock recovery and "adb sideload" the update I get errors saying "unable to mount cache" and when I try to flash via fastboot I get errors saying it can't write the system partition.
I wish we could get some more attention to this thread, this is beginning to seem like it's impossible...
