Completely Ruined my Partitions - Need Glow Restore IMG - Nook Touch General

Hello everyone,
Yesterday evening I bought a Nook Touch with Glow, went home, backed it up, or so I thought (my backup in retrospect is only 75mb and when I restore it, it does try to boot but says "Install Failed"), then proceeded to install android with Glownooter. Most of the programs I tried to launch closed after a few seconds (though I followed the instructions and installed both .zip parts), so I was going to restore and try again.
Following the restore instructions, I blew out the entire Nook partition table in preparation and now I feel I am screwed without external help. I tried everything last night for three hours...
Could anyone upload a stock .img file for me please? I really want to use the device and don't think it would be right for me to return it to the store for an exchange because of a mistake I made. Currently my SD card has nooter on it, but last night I had CWM open with the factory.zip someone posted and tried installing that zip to no avail... I even tried the n2T-Recovery_0.2.
Thank you.

The partition table of the NSTG is the same as the NST.
I am in the same situation, and so far I have not had a huge success reviving mine but perhaps this thread could assist you in the right direction. Remember to save /rom information before trying anything

I know - I read that thread front to back last night and made no progress either.
Am I correct to assume that a backup image from someone would restore all partitions and completely solve our problem?
If so, if someone would upload an image in virgin state it would solve problems for everyone. I'm completely surprised that such an image is so elusive.

Anybody's full backup image will wipe out all your personalized data in /rom and /factory/rombackup.zip.
Generally, AFAIK, all these Nooters can screw up your Nook but not re-partition it or format it.
Make an effort to get to get your /rom back.

Is /rom an item unique to each device, or are you worried about me losing books/login information in "personalized data"? I had done nothing with my device except get past initial startup when I rooted it, so I have no personal items (books or otherwise) invested. I'm sorry if this is a silly question, but I don't understand.
Edit: Also, I used the magic (something) application to delete all partitions from the nook prior to the restore because it would not let me restore until then. If I had known my backup was invalid I would never have done that.

Attached is an image of what my restore contains. It does try to boot, but then says "Install Failed."
Note there is a romrestore.zip.

Yes, that's the idea.
But as Renate mentions, that would overwrite you /rom partition with invalid data from another device (mac address, serial, and things like that).
But in the same situation I managed to salvage my /rom partition, so if I ever install such an image from someone elses' NSTG i coudl overwrite /rom with the data from my own device.
It could be also possible to generate such an image of an NSTG and then carefully unpack, delete the most sensitive files from /rom and repack the image to share. That way no sensitive infromation would be shared/compromised.
If you happen to stumble on such an image, please let me know.
BTW, those /boot files you have, could you pack them in a zip file and send it to me or post it here in the forums? I formatted my /boot partition and I could make good use of yours (no sensitive/personal information contained in there)

I'm throwing in the towel because my /rom partition is gone and I understand all of that now. Tonight I will exchange for another (against my conscience) and make a proper backup before I do anything going forward.
In my research I found this:
search.4shared.com/postDownload/2YsbIxQJ/nook_glow_partition_files__023.html
It is all of the files except rom, and you will find the boot files in the 0 directory.
Good luck, and thanks for the help everyone.

Did you check both the p1 (/boot) and p3 (/factory) partitions to see if you had rombackup.zip?
Of course check p2 (/rom) for devconf.
Try repartitioning your Nook. You'll need CWR on an SD card with ADB or Noogie and Linux tools.

Are you sure you can't recreate the partition table and mount /rom to get access to your files?
It is explained in the thread I mentioned. If so, then it would be fairly easy to recover your device.
Be careful when returning the NSTG to B&N, some of the operations performed are not covered in the warranty and they could want to charge you....
Anyway, thanks for that pointer! I'll see if I can use it to revive my NSTG

I fired up CWR but saw no USB activity on the computer (for ADB). Could you please tell me how to get ADB running? I did download your script and was interested in trying, but only got USB Disk mode on Noogie (which I couldn't get ADB to work with).
Thank you!

ADB on CWR can be a bit tricky.
It seems like the daemon dies sometimes on disconnecting and stuff.
http://forum.xda-developers.com/wiki/BN_Nook_Simple_Touch/Installing_ADB
http://forum.xda-developers.com/wiki/ADB
Boot it up on CWR first, then connect the USB cable.
In Windows it should show both Removable storage and ADB on the taskbar.
Code:
adb usb
adb shell
Make sure that you have the CWR with USB ADB and not Wifi ADB.

Forgive me, but where would I find CWR with USB ADB? I currently have CWM-based Recovery v5.0.2.7 from the Glownooter thread. The 2gb image.
At the bottom of the black screen I have some errors, though:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log

Nothing reacts when I plug in USB.

I did successfully install ADB and the Android SDK earlier, but it is not running on my Nook under CWM and I do not know how to get it on there. The guide says "The Nook must specifically have an adbd daemon running on either WiFi or USB. The stock Nook has no adbd."
Do you know how?

You should have adb.exe somewhere. From a command window in windows (start menu, execute cmd.exe), go to the path where adb.exe resides and type "adb devices": this will tell if your nook is hooked and accessible.

I don't believe ADB is running on the nook, which is currently booted into CWM.
I do see the showing USB Mass Storage Device in device manager, but I cannot access the device as I can in noogie.

You may have the CWR running WiFi ADB (which doesn't make sense to me because you can't select AP).
If you have USB ADB running on CWR you should see on the USB in the taskbar two things, Mass Storage and ADB.

[HELP] Nook boots directly to ClockWorkMod recovery

I just flashed the CWM to my nook, but now when I try to turn it on, it runs directly into CWM recovery menu. I tried flashing to NC_1.3.zip, even tried dualboot, it does not help.

What ROM did you flash? CM7? Telll us specifically what you did.
Did something rather stupid, I did dd if=%path to cyanogen mod% of=/dev/block/vold/179:0, believing that it should write to my uSD card, but it written the internal memory instead. Fixed this by booting into Nookie-Froyo, fdisked the partition, and boot to clockworkmod again to restore the whole thing. Now I lack the ROM partition in /dev/block/mmcblk0p2. Is there a guide somewhere or tool to rebuild that partition?
Hey this is happening to me to I can't get in to anything but recovery.

You need to re create DeviceID, MACAddress and SerialNumber under devconf/ in mmcblk0p2 (FAT).
DeviceID (I used "BNRV200", not sure if it is correct).
MACAddress (I used "11:22:33:44:55:66", not sure if it is correct).
SerialNumber (It is under the SD card door)
...and how can I do that? Which program can I use? I think this'll save me, considering my Nook is unregisterable for some reason...
Try with ADB + CWR uSD card
Boot with CWR card with NC connected to USB.
do adb shell:
# mkdir /rom
# mount /dev/block/mmcblk0p2 /rom
# ls /rom/devconf
# mkdir /bkp
# mount /dev/block/mmcblk0p3 /bkp
# ls /bkp
and pos what you see.
after that:
# umount /rom /bkp
Turn it off.
Take out your SD card then try to boot, sounds like cwm is running off you SD

I think recreating the information within the Nook Color's memory would solve all my problems, since without registration, the Nook stock refuses to update. I tried updating through regular means, but the Stock refuses to take any update or any CWM-flashed ROM.

These steps are not flashing with CWM, they are just entering to clockwork recovery system wich allow you access to NC's internal memory.
You need to create three files:
/rom/devconf/DeviceID
/rom/devconf/MACAddress
/rom/devconf/SerialNumber
and fill them with your NC's info...
I dont know exactly wich data must be in those files...
EDIT:
With these files I can run CM7 but not sure for NC stock...
I'll try anything, even if it's random gibberish. I need my Nook back.

I need that file too.
I just want it as a sample because these files are different for each nook.
How did you lost those files?
If you didnt repartitioned your nook you can look here.
You can access them with CWR + ADB.
I keep giving this advice, I feel like a broken record. Oh well, at least it can be helpful...
Do a hard reboot and take your nook directly back to stocking condition. Hold down power,n, and the volume keys all at the same time for ~10 seconds until the nook turns off. It will flash, and reboot, when it begins to load (if you still have the cyanogen screen, as soon as it appears) hold down all the same buttons again until it goes off again. Do this 8 times total. On the final reboot, the nook will load into froyo, go through the normal B&N registration process and then in settings of the nook OS, erase and dereguster device to complete the wipe. That will send it back to stock.
I have seen this fix anything from a black screen to a completely erased system directory. Give it a shot.

Thanks. But this method only work if you have third partition (factory) intact.
And all I need is a file located at that partition wich I dont have :S
on my first attempt to put cm7.1 on my emmc using cwm I had the same or a very similar thing happen to me.
I somehow ended up with a bad boot partition. I followed a thread on here that had to do with "reformat and a repartition", (cant find it right now) but downloaded and installed these zips through a cwm card then installed an update for b&n 1.4 zip (I was running 1.3 ) but it worked allowing me to go to stock.
Then I tried it again only this time when I first booted to cwm on the main menu I hit wipe data/factory reset then installed zips and all is well.

Backing up p2 (/rom) prior to rooting: Additional precautions?

There seem to be a lot of posts lately from people who have failed to make a proper backup prior to rooting their NST or NSTG. The first reaction to a failed root seems to be trying to restore the image, and of course, a bad image results in lots of heartbreak. I've read Renate's posts patiently talking people through the process of attempting to recover /rom.
I understand that it's the contents of /rom that are unique to each device. In addition to using a disk imager to make a copy of the device, might it also be a good idea to copy the files within /rom to a safe place prior to embarking on any rooting adventure? At least this way, they'd be able to *see* the files and hopefully increase the odds of a successful backup. Also, depending on what gets destroyed during the failed restore, are there other backups on the device?
1. While the new device is mounted using Noogie, is making and extra copy of the contents of /rom a good idea?
2. Are the contents of /boot/romrestore.zip (/system/rom) sufficient? (/rom/BCB has the same md5 checksum, but the only bootcount shows in devconf).
3. The contents of /factory/rombackup.zip appear at quick glance to provide the missing files from devconf). Do /boot/romrestore.zip + /factory/rombackup.zip provide a good backup of the device-unique files?
And finally, is making an image of the device the best way to backup if there's no way to verify it? Would copying the files and doing checksums against the pre-rooting originals be safer? Recreating partitions is not much fun, but could be done with a cut & paste script.
I like playing it safe.
I have full image backups and copies of /rom and rombackup.zip from /factory
/rom is owned by system so you can't read it from a regular app without superuser.
I've thought of making some easy way to back things up.
If you're rooted and have ADB, you just have to adb pull /rom
I've tried to use noogie and give the p2 (/rom) partition a drive letter in Windows Disk Management but it didn't seem to work.

I'm thinking that it might be possible to pull backups during the rooting itself. I've looked at the scripts GabrialDestruir uses in TouchNooter 2.1.31 and I believe it could be done there. The current 2.1.31 nooter script looks like straightforward shell scripting, so I can hack something together there. I've already modified my TN card to add a few files during the boot process to suit my needs, so I'm comfortable with that process.
1. Would there be a major downside to writing the backup files to the TN uSD filesystem?
2. Are /rom and rombackup.zip sufficient? Is /factory/rombackup.zip needed as well, if /rom is bad for whatever reason?
I believe I read that GabrialDestruir wants to migrate TN to a CWM configuration, and I think that's been done for the NSTG already. I'm not sure about the CWM scripts, or even what they're called to search for syntax. Can anyone point me to info on the syntax for the scripts in /META-INF/com/google/android/updater-script as used by ClockWorkMod when installing .zip files? I don't want to try something that will be obsolescent in a few weeks!
I do wonder if a single bootable uSD image could be used to back up critical info from both the NST and the NSTG though. The same files and partitions apply to both, correct? A bootable image that writes copies of these critical files to a VFAT partition on the uSD card would allow newbies to boot, run and then easily copy these files somewhere safe on their PC.

Perfect! Thank you, Renate. Now that I know what to look for, I did find a tutorial thread that I'm reading through.
Looking at the Edify options, I don't see any way to copy files, nor to write to a .zip or tarball. It looks like I can use run_program(program, arg0, ...) to execute busybox commands, but I'd need to look into that to make sure everything needed is provided by busybox.
My initial impression is that doing this via a bootable image with a shell script like TouchNooter for NST uses today might be the best option, especially if I want to add options to recreate partitions. Using CWM .zip files allows different scripts to be run by selecting a different .zip (e.g. backuppartitions, restorepartitions).
I did compare the md5sums of the files from /rom and from both /boot/romrestore.zip (/system/rom) and /factory/rombackup.zip (/system/rom). They do match, so it looks like recovery of both /boot/romrestore.zip and /factory/rombackup.zip will allow restoration if /rom is not recoverable. Do we need both?

[HOWTO] Backup and Restore the System Software

The recently posted rooting method for the KFHD has been great for owners to get started on modifying the device to suit their own tastes. However, I've been a little concerned about everybody jumping in without a safety net in place. There are numerous ways that this device can get bricked. Not to put all of you into a panic, but just getting an eventual OTA update from Amazon might put some of these rooted KFHDs in jeopardy. With no custom recovery on the horizon, I think it's important to have some backup/restore plan to get these devices booting again.
Overview
This backup plan involves making raw data clones of all critical storage partitions required to boot the device. These backup archives can then be stored somewhere off the device. In case of some critical failure that prevents the device from booting normally, these archives can be used to get the device booting normally again. The restore procedure requires the use of fastboot to write the backup archives back to their proper partitions. The use of fastboot requires a working bootloader, so the device will need to boot to the bootloader's bootlogo at a minimum. If the device has a broken bootloader, this guide will not be helpful. There's currently no working procedure for repairing a broken bootloader on the 2nd generation Kindle Fire devices.
To be clear, this guide is not a backup/restore plan for your data. This is strictly for backing up the system software while in a bootable state and recovering it if some modification bricks the device. This procedure has been tested on a KFHD with system software version 7.1.1. Although I have not tested it, I'm nearly certain it will work just fine on version 7.1.5. If the KF2 has the same partition layout as the KFHD, there's no reason why it shouldn't work for that device as well. Check the post on KFHD partitions for details.
Warning: Everything below is inherently dangerous and can potentially brick your device if they are not executed properly. I have tested various aspects to the best of my ability, but you assume all responsibility for performing any of these steps.
Backup
Attached is a small shell script written to do the following…
Make a "kindlebackups" directory in /sdcard (if necessary) and make it user read/writeable.
Create gzipped backup archives of partitions 1 through 11. This includes all partitions except /cache and /data.
Make all archive files user read/writeable.
The entire backup (stock) takes up approximately 550 MB, so be sure to have at least that much available in /sdcard. Root privileges are required for the script to run properly. The best time to use this script is after step two of the published rooting procedure. That's after the second reboot of the process when the device boots up in emulation mode and allows root access for the first time. At this point, the system partition is completely stock and has not been exposed to any modifications. Even if you are past this point, the backups will still be useful for any bootable state that allows root privileges.
Download the script, unzip and place it into your current working directory where you still have access to adb, then run the following adb commands to copy the script to the Kindle Fire and prepare it to be executed...
Code:
adb push backup.sh /data/local/backup.sh
adb shell chmod 777 /data/local/backup.sh
If the device is in the process of being rooted and it has just finished rebooting for the second time...
Code:
adb shell /data/local/backup.sh
If the device has already been rooted and the su binary is available on the system...
Code:
adb shell su -c "/data/local/backup.sh"
The entire process should take approximately 5 minutes. Once the script has completed the backup, access the Kindle Fire's storage area from your computer, then copy the contents of the "kindlebackups" folder to it. The "kindlebackups" folder may be deleted after transferring to your computer.
Restore
To begin the restore procedure, the device must be put into fastboot mode. My factory cable did the job for me, so I have not explored the possibility of changing bootmodes. I developed this guide on a borrowed KFHD and I do not intend to risk the device more than necessary. Unless someone comes forward with a procedure to change bootmodes into and out of fastboot mode, I'm going to say that a factory cable is required for the time being. Besides, based on my experience with the original Kindle Fire, a broken system almost always means there is no way to change the bootmode through it. Since this procedure will very likely be used on a device that cannot boot completely or otherwise has a bad system, a factory cable will probably be the only way into fastboot mode. If you plan to root or modify your system software, invest in a factory cable.
Use the factory cable (with the device turned off, plug into the device, then the computer) to get to fastboot mode. If successful, a "fastboot" logo will take the place of the original "kindle fire" logo.
Decompress the gzipped archive to be flashed… Linux users have gunzip, Mac OS X users also have gunzip and a built-in GUI utility, and Windows users can use 7-zip. The archive must be decompressed before flashing. Skipping this step will brick your device.
Flash the image file(s) back to the device. In most cases, the device will just have to get a working system partition flashed back to it, but the others are available if they are needed. To flash the system partition...
Code:
fastboot -i 0x1949 flash system system.img
- Optionally erase the cache and/or userdata partitions if the contents of either interfere with the operation of the system software. The system will rebuild them on reboot…
Code:
fastboot -i 0x1949 erase cache
fastboot -i 0x1949 erase userdata
Once the process is complete, long-press the power button (~20 seconds) until it powers down, unplug the factory cable, and power the device back up.
Good luck.
Thanks kinfauns. I appreciate everything you did for the original kindle fire. This should help a lot of people.

Copying kindlebackup folder
Thanks for the script - the backup procedure was smooth -
I couldnt find the kindlebackups folder while browsing through my PC and for others like me who wonder how to take these out of your KFHD, here is a simple way - I used a program called Wondershare MObilego (Manage SDcard option under more tools) Backing up was a cakewalk.
I have no affiliation to this tool maker - Just sharing a way that helped a n00b like me. (First rooting experience)
Thanks for the efforts!
BTW, will a backup from a clean device work for other devices instead of the same one which the backup was created from? Just wondering if people who have already fiddled around their root devices can get a fresh start.

I don't know if anybody has packaged the device drivers set up for this device. If nothing else, you can get the device driver installer in the "Kindle Fire Utility" for the original KF and use that. You just have to change the PID from 0006 to 0007 before installing it and should work. Refer to this post if you still have problems...

for device driver information. Again, written for the original KF, but the process for installing device drivers is the same. Only the PID is slightly different and that should get edited in the INF before installation.

Glad to hear it worked out for you. I am not familiar with that program, but the KFHD should connect automatically to a Windows device as external storage... does it not?

I have not tested this and don't have a way to do so. I have some concerns about it, but I'm sure someone desperate enough will jump in and try it out. I know it's too late for some, but my suggestion is for everybody to make a backup if you can and not rely on someone else to give you archives after the fact. It's better to have your own backups.

Then you're first going to have problems getting root privileges. You need to get adb working before you attempt any part of rooting or backing up with this procedure.

This is the correct "product" reported by the KFHD. This and the product ID (0007) are the only differences between the KFHD and the original when it comes to installing the device drivers on Windows.

You can put the the images wherever you want, but you'll need to specify the path to the file. For example, if you are using Windows and put the kindlebackups directory on C:, you just need to modify the command to...
Code:
fastboot -i 0x1949 flash system C:\kindlebackups\system.img
Thank you for posting how to do this. It opens a lot of doors with at least a little security.
I made a backup earlier without a problem, then went ahead and made myself a factory cable(easy to do and worked great- old asus usb cable, 1k resistor, soldering iron, shrink tape and voila!). I feel much better about doing any mods to this device now knowing I can just flash my backup.

Flashing Now Fails

I've been flashing N7 with no issues as recently as over the weekend. Today I tried to flash a new ROM and it failed. Tried a second, different ROM, same result. Do not know what I did. Any thoughts?
Error log would help greatly.
How do I get/generate the log? Haven't had to do it before.
Thanks,

or
Have you tried completely wiping the device? And pushing a ROM from ADB or using a USB OTG and Memory stick?
I had issues with my nexus becoming VERY unstable. Leading to issues.
I completely, and I mean completely, wiped. To the point that all that device basically had was a recovery, and a bootloader.
I proceeded to flash again, BOOM all fixed up.
Is there a new TWRP?
I did a factory restore after wiping everything thing, if that is what you mean?
It was working as expected last week, don't know what I did to screw it up

None of the instructions currently found in this forum alters the partitioning of the N7. Not fastboot & not the custom recovery, either.
You are chasing a red herring I think. That message you see is about the recovery performing a scan to check to see if there is a change in file systems (or partitioning of external devices) ... which might have occurred in preceding (custom recovery) operations, but didn't in this particular case.

You can also soft-boot a recovery without actually flashing it, e.g.
Code:
fastboot boot custom-recovery.img
I suppose you could then poke around and see if it is having troubles mounting any of the normal partitions (/data, /system, or /cache). Look in the kernel boot log of the recovery (cat /proc/kmsg or "dmesg") to see if anything looks strange, etc.
There have been a couple of reports from folks who developed problems that looked like eMMC flash media errors - loss of partitions, failure to mount /data, et cetera. At the moment though, your symptoms are very generic and non-specific, as in "it doesn't boot".
I suppose you saw no errors at all reported on the screen during that stock-install-via-fastboot procedure?

The only error is that it can't open the zip. I've tried downgraded TWRP, then upgrading back. Tried flashing the existing rom.
Nothing has worked. The N7 is functional, just will not allow me to flash

Well, if the source material can't be opened, then there is nothing to be flashed.
So maybe it is better to call this a "can't open files" problem instead of a "can't flash" problem.
Are there any special characters in the file name ... or spaces? If so, try renaming the file so the name only contains [a-z], [A-Z], [0-9] plus dash, underscore, and dot.
The other thing that can happen is if you drop a file in /data/media/0 as the root user, it will show up under /sdcard, but can't be read by non-privileged users via the /sdcard/ path. I'm not sure what the exact details are here - much less why this would effect the recovery (as you would expect everything to be running as root there) - but you can detect this problem by using a terminal emulator, and looking for differences in ownership or file permission:
Code:
$ su
# cd /data/media/0
# ls -ld *
use chown and chmod as appropriate to fix files as needed

Thanks bftb, you are correct it's a can't open zip. No error than fail and it can't open the zip. It says updating partition but nothing changes
The file names are from the developers, once of which I recently successfully flashed. Tried coping the log to the SD card, but unable to find /data/media/0. Do I need to recreate a partition?
(FYI there was an auto-correct typo in my prior post - "su" not "such". Derp)
pmgreen said:

No. (There is no way to do that with the tools we have anyway)
Unless what you mean by "recreate" is rebuild/reinitialize a filesystem in a partition - that's a possibility.
You need to try and figure out why you can't read files.
As a workaround, you can put files on a USB key (FAT formatted, not NTFS) and using TWRP access them by putting the USB key on the other end of a OTG cable.
Your posts are a bit vague - I can't even tell if you have tried other ROM files, whether you checked them to see if they are the correct size/checksum, etc.

At this point, your best approach is still to follow the initial advice of 'ibsk8'. Look in the log file for any further details about errors that occurred.
The logs are typically in /cache/recovery/ or (while the custom recovery is running) in /tmp
Use "adb pull" to get the log file to your PC and have a look at it. If you can't find anything obvious in there, then cut-n-paste the file to http://pastebin.com and provide the link to us.

[Tutorial] LG Gpad v410 5.1 to 4.4 downgrade, root, & internal storage fix.

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:
https://forum.xda-developers.com/showpost.php?p=75787067&postcount=699
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:
http://forum.xda-developers.com/g-pad-10/general/kdz-lg-g-pad-7-0-v410-t3224867

Android LG Drivers:

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.

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!
Thank You, Worked Great
Thanks for making this I was gonna do it but was to lazy lol and thanks for linking my thread and giving cred instead of just linking straight to the kdz thank you

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.

At what point did it bootloop? What was the last step that you took before rebooting?
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 ?
regards

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.
After all process, it shows 16Gb total at storage, 11.04GB available. it works perfectly.
I need the stock V41010d, so I reflash the stock rom rooted at [ROM][STOCK](V410 ONLY)KOT49I.V4101d | 4.4.2 | Rooted + Busybox
Now, my Gpad is at stock V41010d, but I have a question about the boot screen, is it still with white lines and white screen? Any method to fix it?
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.
