Tried updating from 4.2.1 to 4.2.2.
But assert check failed returning above file in results. Somehow it's been modified. No idea when and how.
Anyone running 4.2.1, could you please provide me this file.
Thanks in anticipation.

I have the exact same issue!
Here is the list of only apps with root access in my tab.
Carbon - App backup and restore, Solid explore, Stick mount, SuperSU, System tuner pro and Terminal Emulator.
Thought to seek out the culprit!

Pulled this from the 4.2.1 factory image. I seem to have got past the debuggerd error message now (though I need to revert my build.prop entirely, apparently).
Included build.prop (not yet tested) from 4.2.1 image too.
Working for me and now running 4.2.2.
At your own risk, yadda yadda, not responsible for explosions or anything less terrible, blah blah.
FWIW, I had been using Stickmount and superSU.

Thanks Now 'm on 4.2.2
In the future, If you want to pull arbitrary file(s) from Google N7 factory images, a useful skill set is to figure out how to use "sim2img" utility and loopback mounts (Windows need not apply).
Those system.img files shipped by Google are "sparse ext4 images" - they can not be directly mounted as a loopback, but that's where the "sim2img" utility comes in
The sequence goes like this:
- use sim2img to convert Google image file to regular ext4 image file
- loopback mount reg. image file
- grab whatever files you want (and check user/GRP ownership & modes)
It really is just that easy.
The "sim2img" utility is part of the android ext4_utils toolset. See this XDA thread from the Galaxy S forums for more details. (Yes the N7 system.img files from Google are also in this format.)
cheers

Big thanks.
Replacing the debuggerd file allowed twrp to load the 4.2.2 update.
Also interesting, other than titanium, the only other root app on this device is Stickmount.
Did not work for me ...
I have a N7 3G and the same message when trying to update. Replaced mine with the one from the download, no change, same error.

First of all, thanks a lot to PhoenixTank who provides me the solution. :good:
In fact to make it work, I had to change the permissions allowed on that file named "debuggerd", I checked what permissions were allowed on the original file and do the same on the copied one. I did it with ES explorer in root mod.

You'd need to backup and rename the existing debuggerd then move/copy the 4.2.1 debuggerd file to /system/bin/
Then match the permissions of the old debuggerd (I think it was 644, but I wouldn't swear by it).
The OTA zip should actually go through after that, or at least tell you about a new file you need to fix. You shouldn't lose any data, but you should probably clear cache and dalvik cache.
I did most of this via adb shell, but there are root file managers that can help. If you aren't confident about doing this and how it works, my posting was not really for you. Strongly suggest reading up until you feel confident before you start changing things around in the system partition.

Unfortunately the 3G version is different to the Wifi Nexus 7, and as you've found, the files will not work.
Since I posted, Google pulled the 4.2.1 factory images from the download site - I'm not really in a good position to help you here.
The 4.2.2 factory image might be of more use if you can't source the 3G specific files. i.e. flash the new factory image.
Had this same problem. Will try solution tomorrow morning. Probably will download the links rather than trying to extract them myself (though I may leave that for a later exercise).
Would like to note that I also use StickMount as well as SixAxis Controller, Wifi Key Recovery, AppSync and LMT Launch err.
Seems like stick mount is the common one though.

Thanks guys
Those 2 files worked.
I got past "Verifying current system" and am now on 4.2.2.
I wanted to try to get the files myself as an exercise but Google pulled the 4.2.1 images from their website.
What is weird... is that I noticed a /system/bin/debuggerd.bak file that I didn't make myself, don't know what did (though StickMount seems to be the current suspect).
The weird thing is that debuggerd and debuggerd.bak were exactly the same.

I want to do this, but I can't find the system/bin folder, what root explorer apps do you guys use?
EDIT: Used Total Commander, copied the permissions from old file to new and voilah! It worked.
No need to download build prop.
Now I am on 4.2.2
EDIT 2: Now WiFi only says SAVED and not CONNECTED.
Just want to say THANK YOU!! I've been researching this error since Friday and finally found the solution here! And yes, I too have Stickmount!

Can only recommend that you clear cache and dalvik cache. I have not experienced Wifi issues since the update.

can i do the reverse ? i.e. ext4 partition back to flashable img ?
that way it would be easier to root as I just need to dump a copy of su into it then flash.
And for Windows, just get oracle virtualbox(or your favorite VM, even virtual PC should work) and boot a copy of debian

Yes. I did exactly the same thing, but for 4.2.1. Guess I need to repeat it now for 4.2.2. Note in this case "flashable" means the fastboot way (as with the Factory ROM flashes), not via custom recovery.
Uhh let's see - the script tool used for re-packing is ./mkuserimg.sh - see the links I provided above
I need some help... I'm rather noobie. Had issue with upgrading to 4.2.2 so copied the debuggerd and build.prop files over to the system/bin directory. Still failed to upgrade. Tried it again today and now the N7 will not boot up. I can see it's on but it just stops at a blank screen. I have stock 4.2.1 w/root. Stock bootloader. I'm thinking its refusing to boot because I forgot to change the file permissions on the debuggerd file but not sure how to try and fix it. Please advise...
UPDATE: Managed to flash the system partition for 4.2.2 so hoping I'm good to go. Asked this question in another post but is it necessary to update any of the other partitions?

Hello,
many users complain that since lollipop their system partition size doesn't reflect the actual system of the block device. Therefore, they can not install some extra in this partition( busybox, big gapps packages,etc.).
This is due to the system image size specified when building the rom:
One of the parameter of your system partition(which has been hardcoded in some config file, I.e. BoardConfig) is its size, but if the block device(i.e. the part of your internal storage that will be mounted for the system partition)'s size that is mounted is larger than the system partition's size than you will loose some space.
Fortunately resize2fs executable allows to modify an ext2,ext3,ext4 partition size:
This package simply resizes your system size to match the size of your block device size.
It does not alter your partitions table just reclaim the unmounted space.
Instructions:
Boot on a twrp 2.8.x.y TWRP recovery
flash the package

Hello,
It doesn't work on my fresh install of 5.1 (stock and on nexus 7 2012 wifi). TWRP says :
Code:
Error executing updater binary in zip '/sdcard/resize_manta.zip'
Error flashing zip '/sdcard/resize_manta.zip'
I've tried both with TWRP and with nexus root toolkit. I've redownload the zip. Still the same.
Any idea ?

I'm probably, no ... surely ... completely out of my depth, but is there any chance this was done intentionally to keep Bad Things(tm) from being put onto the system partition? It seems like a horrible oversight so I'm wondering if it was intentional. Of course if a hack was in a position to write the the system partition, then it is just as likely in a position to delete something to make room, but that might then be noticed.
Just something that popped into my head after all day cooking for the in-laws and now trying to decompress with some Nexus hacking
Both the script and the TWRP functionality worked fine on my N10. But it still doesn't leave much space on /system when running a Marshmallow-based ROM. Meanwhile, I have 22GB free on my internal user storage (emulated SD card).
I'm curious if it would be possible to shrink that user partition size some and add that space to /system using this script or TWRP? Running fdisk -l /dev/block/mmcblk0 in adb shell shows only one partition, so I'm not totally sure how things are being sectioned off internally.
I used this for the main reason to fix the issue of insufficient space in system partition that wasn't letting me install gapps, I don't know why but after I did the mod, and flashed aicp is showing 700mb total on system partition in tibu, I thought it's supposed to be 800mb on it, no biggie since I fixed my main issue but I only have 13mb left in system.

PIT files
My nexus 10 has the boot loop problem and I think I have been left with the only option of Re-Partition but I need the PIT file. Can anybody help or provide this file?
I have tried everything else (fastboot, adb, temporary custom recoveries, Nexus Root Toolkit) with no success.
Every new lollipop update has shrunk the system partition and now with 5.1.1 for the first time the system partition has 0.0 mb free.
I've seen a pattern with every update but now they really made sure there is no free space at all. I remember when I had like 50 mb free.
I really wonder if they do this intentionally to make it a little more difficult to root. I know how to free up some system space so I can install busybox, I usually just delete google+, but this was never necessary up until 5.1. But even then there was about 0.3 mb free.
I wanted to make sure that it wasn't filled up because of leftovers from previous updates so I made a complete fastboot wipe, both erase and format every partition, and then installed 5.1.1 manually through ADB. But it made no difference.
I don't think that are shrinking it. It's just a problem on the nexus 7. I noticed the same on mine. The build is just bigger so they use exactly the amount of space they need. May be why some units get soft bricked during the update. I gave up on the nexus 7 though. Doesn't run how it used to and lollipop seems to be just too much for it. My samsung galaxy s6 still has 500mb free of it's system partition and is running lollipop. I got a free galaxy tab 4 10.1 when I got 2 new phones and I have not touched my nexus since.
Previously when installing Kali linux and the wifi "hacking" toolkit i resized my system partition. Now when i search google i cannot find the guide on how to resize the system partition on the nexus 7 without running the risk of bricking the device.
Does anyone have any memory of what im talking about? It was pretty simple as i recall.

But they should be able to avoid filling the system partition to the brim, the images are still device specific and someone at Google must know that leaving 0 space left is bad. Now with the 5.1.1 update it even was as if there was negative free space because i removed Google Plus which should've freed up 35 mb but I only got 8. It was enough for busybox but still weird. I do think they are making these little problems to mess with us who root. With this and that you can't install otas anymore if your not 100% stock.
The system partition is not full and there is a fix
I had the same problem with my Nexus 10 but not my Nexus 4. I have also come against this after updating the Nexus 7 for my son.
This was fixed on my Nexus 10 by running a script from this link:- http://forum.xda-developers.com/nexus-10/help/qa-reclaim-free-space-partition-t3055387
As you will see, it is not that Google is filling the system partition but that there is a problem with the update which sets the partition size to the size of the system image rather than the full size of the partition hence a seemingly full partition.
The script comes in a zip file and when I ran it on my Nexus 10, as promised, I got the full system memory back reclaiming in the order of 150Mb.
As you will see in the thread, people have tried it for the Nexus 7, as did I, and it does not work but the developer says that this is to do with the 'system partition's block device' being different and that this can be corrected for the Nexus 7 by editing the 'sh' file and entering the correct path for the 'system partition's block device' which is also shown in the post.
I have not had the confidence to do this but hopefully this information will help people or at least point them in the correct direction. All the best.

i tried many times and finally was able to flash a modified zip successfully, however, the system partition is still around 640MB (with just 448K free space left) same as before the flash.. is it because of the zip not working or because my N7 2012 8GB really just has this maximum size for the system partition?

I ran into this too and couldn't install Busybox. I used ES File Explorer in root mode and moved the IMEKorean and Hindi fonts, maybe one or two other minor things, to the /sdcard partition. I got enough space back for busybox plus a custom font I wanted to use.

Sorry I have been so long in replying I have been very busy. As I said I did not feel confident or indeed competent to amend the script myself I just wanted to point out that people would perhaps be better following this line that I had found in the Nexus 10 forum and worked rather than continuing to blame Google for filling the system partition.
I no longer have the Nexus 7 to test your script on as I said it was my sons and not mine. He was fed up of his Nexus 7 being so slow so I installed the Cyanogen Mod latest CM12 update for him.
I have however looked at your script and the only thing that I note is that it does not include the following two lines.
ui_print("");show_progress(1.34, 2);
ifelse(is_mounted("/system"), unmount("/system"));
I am aware that the first line is not necessary but the second line checks to see if the system partition is mounted or not and if it is, it unmounts it. If the partition is mounted then the script will not work.
Sorry that I am not much help, my expertises if I have any was with windows when I was working, which was a long time ago now.
Good luck with it anyway.

anyway before further information gathered, im done with this as my n7 is also a backup device at the moment..
EDIT: If you are coming here for the first time, this guide should still work, but @PorygonZRocks has created a flashable zip that should deal with a lot of these issues automatically. You can check out his post here:

This method will indirectly allow you to root the LG Gpad v410 after it has been upgraded to Lollipop 5.1.1. Yes. Rooting LG v410 Lollipop. It's through a downgrade, but it works.
It took a while to get working, but here's how I did it. The process is straightforward, but the details matter greatly. You will brick your device if you mess up. Please read everything *first* before you do anything. Be sure you understand the process. I'll try to explain what's going on along the way.
An external SD card is extremely helpful for this process. You *could* adb push everything, but that will tedious.
First, you need some files.
The 4.4.2 KDZ which is a TEST OS, but it can be rooted and it downgrades to a Bump'able bootlaoder:

Parted for Android. You can probably find it other places, but I found this file:https://dl.dropboxusercontent.com/u/84115590/LG%20G2%2016GB%20Solution/sdparted-recovery-all-files.zip
EDIT: There seems to be a lot of confusion here. My bad. All you need is the file named "parted" from this zip file - nothing else. Just put that one file in the root of your external SD card.
https://dl.dropboxusercontent.com/u/84115590/LG G2 16GB Solution/sdparted-recovery-all-files.zip linked from here: http://www.**********.com/your-32gb-lg-g2-shows-only-16gb-storage-space-heres-the-fix/
EDIT2: The dropbox link is down. I've attached the file directly.
The Candy5 ROM (This will potentially save you some manual steps. Somewhat optional, but highly recommended):

LG One Click Root:
http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
(You may use Purple Drake or whatever else you want. They all use the same root script as this does and the GUI is helpful for novices.)
Android SDK (specifically adb.exe. After installing go to SDK Manager and ensure that Android SDK Platform Tools is checked):
http://developer.android.com/sdk/index.html
For clarification below, when I have commands in "quotes" they are Windows commands. When they are in `backticks` they are commands that you run inside of ADB which actually run on your device....as root. Root can screw things up. Please be extra cautious. If you blame me for messing up your device I will laugh at you. But that's not gonna happen, right? Good. Let's go.
Now that you have everything, put it all into a folder where you can access it easily.
Install the LG Drivers.
Install Android SDK (or otherwise get adb.exe).
Extract all of the archives.
Move the KDZ to the LG Flash Tool 2014 folder.
Put the tablet into Download Mode by powering it off, holding VolUp, and plugging in the USB cable. Press VolUP when instructed. You must be in Download mode before continuing.
Run LGFlashTool2014.exe. Select the KDZ file. Click "CSE Flash". Click "Start". Select "English" and click OK. Do not change anything else.
WAIT for the flash to continue. If you really want to brick your device, here's a good opportunity.
The device will reboot into Android 4.4.2. You will only have 4GB of internal storage at this point. DON'T PANIC! We are fixing it.
Enable USB debugging.
Connect the device.
Install and run LG One Click Root. Wait for the device to be rooted before proceeding.
Copy the Flashify apk, TWRP image, and Candy5 ROM to your external SD card.
Install Flashify and flash TWRP to the recovery partition.
Use the Flashify menu to reboot in to recovery.
DON'T PANIC! You will get white vertical lines on the boot screen from now on. They only show up during boot animations. A small price to pay. This may be fixed at a later date. for the time being! Thanks to marcsoup's first post ever, we have a fix! Details below. PLEASE click this link and thank him!
Things get tricky here. Copy parted to your external SD card and then run "adb shell" from Windows to get a shell in TWRP.
In TWRP, unmount /data by tapping Mount > uncheck Data.
`cp /sdcard/parted /sbin/` This copies the parted binary to /sbin so it can be executed in the path. I had trouble running `/sdcard/parted`, but YMMV.
`chmod +x /sbin/parted` Make it executable.
`parted /dev/block/mmcblk0` Run parted against the internal mmc
`p` Prints the partition table.
`rm 34` Deletes partition 34 labeled "grow". This is the root of our problem. The KDZ apparently only creates a 4GB partition, I assume so the test build has maximum compatibility with all sized devices.
`rm 33` Deletes partition 33 "userdata"
`p` Print to verify
`mkpartfs` Create a partition and put a filesystem on it. If we only expand the partition it won't help us because the filesystem is still only 4 GB.
a) name: userdata
b) type: ext2 (the tool only supports ext2. This is ok for now.)
c) start: 3439MB (the end of part 32. IT MAY BE DIFFERENT FOR YOU!) Be sure you do not omit the MB part otherwise the offset will overwrite another critical partition.
d) end: 15.8GB (where "grow" ended above. IT MAY BE DIFFERENT FOR YOU!) Be sure you do not omit the GB part otherwise the offset will overwrite another critical partition.
`p` Verify. For me it did not name the partition properly. Gotta fix that.
(if necessary) `name 33 userdata` This is critical for mount to find it in /dev/block/platform/msm.sdcc.1/by-name/ on some/all ROMS.
`p`. Verify one last time. Compare it to my partition table in the attachments. If you want to brick, delete some random partitions here.
Flash Candy5 with TWRP. It's only 239 MB, so it will flash quickly. I do this because Candy5 will reformat mmcblk0p33 from ext2 to ext4 for you. It does this as part of it's system boot, apparently. If you install a different ROM that does not do this, you can reformat it by running `make_ext4fs /dev/block/mmcblk0p33`. If your ROM does not have make_ext4, it likely has some differnt method to make an EXT4 filesystem. `/system/bin/mke2fs -t ext4 /dev/block/mmcblk0p33` may work better. Just flash Candy5 and be done with it.
Tap Wipe > Swipe to Factory Reset.
Tap Reboot > System.
WAIT!!! It will take a minute for the ROM to start the first time. You will have white lines and and possibly a white screen. WAIT. It's moving the DEX files to cache, formatting a partition, creating default folders on the internal storage, and several other things. WAIT! When the screen goes dim or turns off then it's ready.
Cycle the display or turn it on. You should be at the Candy5 lock screen.
USB debugging is on by default. Run "adb shell".
`mount | grep userdata` Make sure mmcblk0p33 is mounted.
`df` Make sure /data is 11.3 GB (or whatever size it is on non-16GB devices).
HELL YEAH, you downgraded, rooted, and fixed the partition problem. Enjoy your tablet!
Thanks to dopekid313 for finding the KDZ.
Thanks to timmytim for Candy5.
Thanks to the creators of the root script, flashify, TWRP, and XDA for being so awesome.
Thanks to marcsoup for fixing a fix to the white lines.
Thanks to navin56 for the partition dumps. PLEASE thank his post!
White lines fix.
What we are going to do is flash the aboot partition with the stock image provided by navin56. I've removed the extra files from the dump, so simply download aboot.img.7z below. Unzip it using 7zip.
These commands are to be run in TWRP. Reboot to TWRP recovery and connect with "adb shell". All of the following commands will be run in ADB under TWRP. If you cannot figure out how to get here, please post in the thread and someone will help you. Onward:
If you do everything correctly then you don't have to reflash your ROM and you won't lose data. This process can be done any time after flashing the KDZ, even before you follow the steps above to resize the userdata partition. It's a completely separate process.
Unzip aboot.img.7z so you have the file named aboot.img. You should also make sure that aboot.img's MD5 sum is e97431a14d1cee3e9edba513be8e2b52. Do not flash the 7z file. Please.
Copy aboot.img to your external SD card. It should live at /sdcard/aboot.img
Boot to TWRP and run "adb shell"
`ls -al /dev/block/platform/msm_sdcc.1/by-name/` Let's make sure we are flashing the right partition. On my device "aboot" is /dev/block/mmcblk0p6. You should verify this on your device or you WILL brick your tablet.
`dd if=/dev/block/mmcblk0p6 of=/sdcard/aboot-fukt.img` Let's back up our current aboot partition before we go flashing things just in case there are unintended consequences later. Be sure you have the same partition that "aboot" referred to in the 4th step or you have just backed up the wrong partition.
`dd if=/sdcard/aboot.img of=/dev/block/mmcblk0p6` Be sure the file exists, is the correct aboot.img, and you are flashing the right partition. You have been warned!!
Reboot TWRP and enjoy your boot animations again.
If I missed anything, please let me know. As far as I know this is the very first tutorial that details what is necessary to accomplish this. Please hit the Thanks button on every thread that you visit to download files!
FAQ:
Q: Why do I only have 11.3 GB of space when my device is 16GB?
A: The entire internal SD card (eMMC) is 16 GB. Gotta have someplace to install the bootloader, recovery, android, the modem OS, the secondary bootloader, the cache, the resource and power manager, and all of the other partitions necessary for the table to operate. Please look at the second screenshot in the OP. All of those 33 partitions take up room on the internal card. Fortunately ALL of those partitions ONLY take up about 4.4 GB. Hence the 'userdata' partition is ~11.3 GB.
If anyone wants to use my work to create a flashable zip to make it easier for novices, please do so. My problem is solved and I don't have the time to create the zip. Please post any questions and I'll gladly answer them! I'm so stoked that we have a usable downgrade method now!

Of course! If you hadn't obtained the firmware then we'd all still be looking for a solution. It pisses me off to no end when people try to take credit for other people's work. We all just need to realize and acknowledge that we are simply standing on the shoulders of those who did the work necessary for each of us to do our work.
I just noticed since we formatted the userdata it screws up TWRP. It won't mount Data and it says the settings are corrupted

Is this after you've rebooted into Candy5 and the partition is reformatted as ext4 (or you've done so manually)? TWRP may not be able to mount an ext2 partition.
EDIT: I just tested this. Following my instructions and flashing to Candy5, TWRP sees mmcblk0p33 (userdata) as the full size and mounts it at /emmc.
For clarification, after you run the parted commands, it will mess with the partition table and TWRP will most likely not be able to see it to remount it - at least not until after a reboot. This is why you need an external SD card from which to install ROMs.
/data not mounted
Edit: nevermind. The partition 33 was still ext2. I had to run make_ext4fs /dev/block/mmcblk0p33 and now I am able to mount /data. Thanks.
Thanks for taking the time to help us.
I followed the steps and till 33 I am good. But once I am in Candy5, I am not able to adb shell (adb not recognizing device eventhough usb debugging is on). I rebooted to recovery and adb works there. But my /data partition is not enabled in TWRP. I am not able to check it either under Mount in TWRP.
Code:
mount | grep userdata
is empty
Code:
df
does not show data
I tried this and my tablet bootlooped. I was able to get into fastboot and restore. I would GREATLY appreciate it if someone who has the time, would kindly donate their valuable time to into making an exe zip or something.

Zip
I would really appreciate a zip file as I have never been savvy with adb and for whatever reason it doesn't want to work on Windows 10.

A zip file for what part? The only part that requires ADB directly is to fix the internal storage. You absolutely have to flash the KDZ and then root before you can do anything. If you are on 5.x then you have no possible way to root, much less flash a zip file.
If you tell me what exactly you are having issues with I will try to help.

The adb part is the part im having issue with. Everything else is flashed already. I was wondering if you could make a zip for the adb part so I can just flash it through twrp.
thanks for the great help. it did work perfectly to regain the lost space.
what about white lines ? is there any solution for that problem ?
I have tried flashing back stock recovery extracted from kdz, dd' but didn't help.
Now i am thinking of flashing back the aboot.bin extracted from original kdz or i can dump ".img" from another working device. (i have 4 similar devices)
what is your opinion i m not a developer and i need your advise. should i go ahead and which partition should i dd ? aboot or abootb or boot ?

I have no solid evidence of this, but I suspect that the white lines are caused by a display driver issue where when the bootloader hands over control of the display to the kernel it doesn't get reinitialized properly. I have no ideas as to how to get rid of that at the moment but if I stumble across something I'll be sure to post here.
While I'm not an Android developer, I've been a Linux admin for 10+ years and have a lot of experience with Android devices. I'd be really hesitant to go flashing things ad hoc. While Download Mode may save you if you flash the wrong thing, I'm not entirely sure what the limitations that you may run in to with a locked bootloader are.
After having this device for months on 5.x and FINALLY being able to downgrade and run custom ROMs with root, not seeing a boot animation is a pittance to pay. But I'll keep looking.
i have same problem entered in TWRP but when ADB sheel thorough DP tools it didn't connect to my device. i m also using windows 10
Do I need to Re-mount Data ? I press format data button at TWRP and mount data. It looks work great.

Hello,
Thanks for the great work. unfortunately I am facing some difficulty, starting from step# 16 "Things get tricky here", how to run"adb shell in TWRP?
also can I use minimal_adb_fastboot_v1.1.3_setup.exe as mentioned in the link in the OP http://www.droidviews.com/your-32gb-lg-g2-shows-only-16gb-storage-space-heres-the-fix/ ?
also I noticed the path have been used includes 'parted' folder, but the folder I have after unzipping the parted zip called 'sdparted-recovery-all-files', do I rename the folder to 'parted' instead?
please help and excuse my broken English.
I'm also having trouble with the adb shell step. When my device is powered on normally, adb commands work. However, in TWRP mode my computer can't recognize the tablet, mount properly, and copy over parted. All the steps have been identical to this point. Any ideas?

You shouldn't need to remount or format data. The parted command nukes the filesystem and creates a new one formatted as ext2. At this point the running kernel has the old partition table loaded and won't know that the partition has been extended. Simply flash Candy5 and reboot at this point and it will reformat the userdata partition.
See above for the white lines during the boot animation. Known issue, no fix in sight, doesn't really matter.

You only need the sdparted-recover-all-files.zip from that site. "parted" is not a folder, but the binary (without a file extension) inside of that zip file. Copy that file to /sbin and you are in business.

I'd recommend installing the SDK and pulling the drivers from that. Alternatively, you can try the drivers here: https://github.com/koush/UniversalAdbDriver.
Technically, when I ran the "parted" commands I was actually booted in to rooted 4.4.2 from the KDZ; I wasn't actually in TWRP. It's just not a very recommended way of going about it. I explained how to run all of this from TWRP, but there's no technical reason that you *can't* run this from Android. You just *shouldn't* because you can't cleanly unmount the filesystem and it theoretically could cause filesystem corruption. I just figured that I don't care about that partition getting corrupted since it's getting wiped out.
Hi,

This have two effects, as far as I know:
I can't install any Gapps greather than pico.
My apps seem to be installed in the system partition. Therefore, once it is full, the whole system gets broken.
I can't barely have apps without Trebuchet crashing in LineageOS or the app optimization failure in the stock ROM.
I have tried to increase the system partition manually by using parted and increasing the number of sectors:
System before: 1253376s to 2891775s
System after: 1253376s to 5963775s
But TWRP seems to detect the system partition always as 700MB, no matter the repartition that I have made.
I am wondering if you have ever been able to increase the system partition or if there is any room with a bigger one.
Thanks!

Cannot boot recovery partition failed
Hi everyone,
I have an issue,
Yesterday I tried to install LineageOS 16 and GappsPico
Since my Manta Nexus 10 only have space for 700M, I couldnt install any type of Gapps.
So I do a partition changed.
After deleting and recreating partition, I mistakenly reboot the linux kernel. So it means my Nexus doesnt have any TWRP or anything
Right now, if I pressed power + volume up - hoping to get the recovery option - which I dont get, I only got start.
Is theres a way to fix this? or its just doom for me?
really appreciate it

@tongqabiz This may help you: https://forum.xda-developers.com/showpost.php?p=77992510&postcount=3
Yes it's possible. YMMV.
I was able to grab some space from the userdata partition using this guide: https://forum.xda-developers.com/nexus-4/general/guide-increase-nexus-4s-partition-space-t3800264
This guide is for Nexus 4s, but was taken from other guides built for other Nexus devices, so I took a chance with my Nexus 10 manta. The guide explains how to take the space from the cache partition which also works, but i repeated the process to set the cache back to its default size, and take the space from the userdata partition instead. Now I'm able to flash LineageOS 16 and open-gapps pico. I have some display issues with icons disappearing, and I don't seem to be ale to set any wallpaper, but I've not seen anything else causing any problem (yet). I've rooted it using addonsu (specifically for LineageOS I think?) https://mirrorbits.lineageos.org/su/20190709/addonsu-16.0-arm-signed.zip, and installed remote desktop and busybox in order to run kali.
I had to repeat some steps in the guide where i got some odd error messages about device busy and stuff e.g. when running mke2fs on newly created partitions. Naturally, don't expect to keep any data on your device if you follow this guide, and also expect to brick your device if you're careless with entering the commands.

Hi,
I thought there was a TWRP Special image written for SELinux (TWRP-3.1.1-0-manta.img MD5: 4290afd6b1697d7f7b0d958131010676) written specifically for N10 to address this issue.
It is not the one from the TWRP site tough. Not sure where i got it from either. Check for the above checksum once you find it. I guess can't post any URL's or upload anything atm.
Cheers :fingers-crossed:
