My Nook Simple Touch (1.1.2) is now not working because I wiped ALL the partitions before attempting to restore a backup (which I didnt know was bad at the time)
Notes
1. I have two backups:
a) the first is 239mb which contains my ebooks and pdfs
b) the second is the boot partition (77mb) - I backed up again when when noogie was on micro SD
2. So basically (both backups) I backed up the NST without selecting the whole physical drive.
3. After a failed root, I tried to restore the backup (and seeing it fail), I decided to wipe the whole partition before attempting to restore again :crying:
4. Are there any restorable backup images that can be downloaded online? Or anything which can restore the partition table including the ROM partition with the serial address etc.
5. Please help me restore the Nook back to factory or any working state. Cos AFAIK i've bricked the device.
p.s. I have tried touchnooter and installed touchformatv2 but all I get now is a Read Forever load screen. N2Tsecurity doesnt work without the ROM partition.
Please Please Help Me Im so sad (I know this is down to carelessness on my part but I really need help)
Did you really wipe all the partitions (like write zeroes over the entire physical drive)?
Or did you just try to repartition it?
The question is whether you truly wiped out the /rom and /factory partitions.
Sometimes partitioning them correctly you can rediscover the file system.
The /rom partition is necessary, even ClockworkMod needs to be able to see it.
The /rom info is replicated in /factory/rombackup.zip
Renate's solution may work.
Also, there is a tool called testdisk available for linux that I've used to recover data and partition layouts before; I would expect that it may work a champ for situations like yours.
To use it, you would need a linux box or find a windows port and boot the NSTG or NST from the noogie disk.
Testdisk can recover deleted partitions automatically, including the all-important /rom partition.
That one's important because it contains device-specific info for your NST. It'll do it automatically, but you do need to read up on what commands to give it. You can also rebuild the table manually using fdisk (and I've done so successfully before.)
A windows file recovery utility might let you recover /rom as well (or the files from it.)
You most need the contents of /devconf, and there are lots of files there. I am not sure which ones are absolutely required.
I didn't want to trouble anyone, but I really couldn't find any thread on the same topic as this one.
Also, I don't have ten posts, so I can't post direct links. I'll have to post them in plain text.
I'm a generally disk-space conservative person.
When Android version 4.2.2 was released, I tried updating but without any luck (update failed).
So a couple of days later, I factory reset my Nexus 7, then I truly wiped it and proceeded to flash 4.2.2 and root the device.
No custom ROM:s.
Yesterday, I randomly checked my storage information, just to find that 4 gigabytes out of max 6 gigabytes storage was used.
See puu.sh/2fe9V for an image.
I'm a newcomer to both xda and Android and I followed several tutorials whilst doing this. One of them led to me bricking my device.
I wish I could, but I was only able to track up one of the ones I followed;
blog.laptopmag.com/how-to-hard-reset-a-bricked-nexus-7-with-your-pc (this is the one that was successful).
I'm guessing that I may possibly have accidentally created some other partion or something similar.
I would really appreciate some help in this (to me) confusing topic.

Could be, but then the Google factory images do not discriminate between 8/16/32, and in this case the OP used a factory image.
@Zsded
I had this happen to me the other night (in the middle of doing something else). The long & boring story follows, but let's begin with a solution: The partitioning data did not get changed, but mysteriously the /data filesystem got created with with only about 6-7 GB of capacity. Re-creating the /data filesystem using the "Format data" operation in TWRP will create an ext4 filesystem of 29 GB or so.
You need to backup everything worth saving and re-create the /data filesystem. This can be accomplished (for instance) using the "Format data" operation in TWRP. But - again - this destroys everything in /data including everything in /sdcard. (Note it does not touch /system or /cache though - so your bare ROM is still there)
What you might want to do is the following:
1) back up everything in /sdcard that you want to save
2) make a full Nandroid backup of your current ROM
3) get copies of the TWRP Nandroid backup off the device (on to the PC)
4) perform the "format data" operation in TWRP (iirc it is in the Wipe sub-menu)
5) copy your Nandroid backup back to the tablet***
6) restore the Nandroid backup (or just the data partition if you prefer)
7) Boot into the ROM and copy the saved contents of /sdcard back onto your device from your PC
*** This is a mouthful. On a fresh /data filesystem, TWRP (v2.4.1.0, anyway) wants to find its backup folders at
/data/media/TWRP/BACKUPS/<device-id>/*
But if you use MTP with the OS to copy the nandroid backup files, you will only have access to /data/media/0/* (the "sdcard" mount point) using MTP So, you might need to copy the files and then using a root shell or the custom recovery, get a copy of your TWRP folder into /data/media/ e.g. with TWRP recovery booted:
Code:
adb shell cp -R /data/media/0/TWRP/ /data/media/
OK, now for the long and boring story.
I had something identical happen to me the other night - I have a 32G N7, and it ended up showing only 6.5 GB total in /data. Because of the sequence of events involved, I don't know the exact cause, but using TWRP to re-create the /data filesystem as explained above solved the problem.
First, some background so you will know why I don't know the cause (get a beverage, this is going to be a long post):
The other night, I decided to capture Nandroid backups of every N7 factory ROM from JZO54K through JDQ39 (4.1.2 - 4.2 - 4.2.1 - 4.2.2). My plan was to do a factory install of JZ054K (4.1.2) and then apply each of the OTAs in sequence. So, I backed everything up (including using a certain busybox version of "tar" to backup about 2.5 Gigs of stuff from the /sdcard mount point), and completely wiped the device and did a fastboot install of 4.1.2 (JZO54K) nakasi (WiFi N7) factory ROM.
The ony thing that I did not do in the initial step was flash the bootloader - I left the 4.18 bootloader in place (initially). I did not follow the factory install script; instead I used the following sequence:
Code:
fastboot erase boot
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot erase cache
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot format system
fastboot format userdata
fastboot format cache
fastboot flash system system.img
fastboot flash userdata userdata.img
The above installed the JZO54K factory ROM - but with the newer 4.18 bootloader still in place.
For each of the OTA package installs & nandroid backups, I would "soft-boot" TWRP (thus leaving the factory recovery still flashed on the tablet), e.g.:
Code:
C:\foo> fastboot boot openrecovery-twrp-2.4.1.0-grouper.img
C:\foo> adb push 094f6629314a.signed-nakasi-JOP40C-from-JZO54K.094f6629.zip /cache/update.zip
C:\foo> adb shell sha1sum /cache/update.zip
C:\foo> adb shell
# cd /cache/recovery
# echo '--update_package=/cache/update.zip' > command
# exit
C:\foo> adb reboot recovery
... (OTA runs, device reboots into OS, perform shutdown, boot to bootloader) ...
C:\foo> fastboot boot openrecovery-twrp-2.4.1.0-grouper.img
... take a Nandroid backup (including recovery partition!)...
Now, as it turned out, before any of this had taken place I had noticed filesystem corruption in my /system partition. Because I was making Nandroid backups for reference/archival purposes, after each OTA install, just prior to making the nandroid backup (with TWRP soft-booted as shown above), I did a filesystem check on system and data:
Code:
adb shell e2fsck -f -n /dev/block/mmcblk0p3
adb shell e2fsck -f -n /dev/block/mmcblk0p9
(for Wifi/nakasi/grouper devices, mmcblk0p3 is /system and mmcblk0p9 is /data).
The reason I mention this is that I was focused on making sure that there were no filesystem errors (there were none). Had I been paying attention, I might have noticed that something was wrong with the allocation size. But, read on...
When I finally got finished (3 OTAs and 3 Nandroid backups) I decided to restore the contents of my 2.5 Gb tarball. Nothing should been in /data except for a couple (TWRP) Nandroid backups. So, I start restoring the tarball... and after a good long wait ... tar exits due to lack of space. WTF?
Well, /data and /sdcard were mounted (in TWRP), so I did a
Code:
adb shell df -k /data
and it showed a little over 4.5 GB used ... in a 6.5 GB partition - WTF?
Now, because I wasn't watching carefully, I can't be sure what caused the small filesystem in a big partition, but here's my theory:
Because the OTAs are designed to leave /data and /data/media/* alone (more or less), that means that the /data filesystem was only created once: it would not have been destroyed & re-created by the successive application of the 3 OTA bundles that took me from JZ054K -> JOP40C -> JOP40D -> JDQ39.
To me, that says that one of the two following initial operations was the culprit:
Code:
fastboot erase userdata
fastboot format userdata
OR
Code:
fastboot flash userdata userdata.img
What is rather shocking about this is because of the way that I did things, I had the newest bootloader on the device when I did this - v4.18. I wouldn't have been surprised if an older bootloader had a bug that got fixed... but it surprises me that the very newest bootloader seems to be implicated.
But anyway - to recap - your partition data has not been altered. AFAIK, nobody (but Asus/Google) knows how to do that as it probably requires talking to the device in APX mode. Somehow, whatever recreated your filesystem in /dev/block/platform/sdhci-tegra.3/by-name/UDA ( userdata ) mysteriously created a filesystem substantially smaller than the physical partition size.
My suspicion is that it is a bug in the bootloader.
good luck
Actually all you had to do is do a factory reset in the recovery, and reboot. BAM - all your actual storage is back

Factory Reset in the recovery does not recreate the ext4 filesystem, it only does deep removal (rm -rf) excluding /data/media. That won't solve the problem of having a tiny filesystem in a huge partition; same filesystem - same max capacity.

Strange. After I flashed the stock 4.2.1 after playing with some custom ROMs - I, too, had only 6GB available, but then I did either factory reset/wipe data or something else - and BOOM everything was fixed

Thanks a lot! This solved my problem and I'm now back to 27 gigabytes (which should be somewhere around the promised 32 gebibytes).
I truly appreciate it. I would do more than just to thank your post, but I'm kinda out of ideas (and money).

@Fatal1ty_18_RUS
There have been a couple of other reports about "6 Gigs in a 32 GB device". I just dismissed them as folks not being aware of how much space they were using (e.g. Nandroid backups) - until it happened to me.
Enough strangeness seems to be present to make me nervous for folks that don't have a lot of *nix experience to sort things out when they get mucked up.
The other thing I didn't mention in my story was that restoring a tar file into the /sdcard mount point using a root shell in TWRP (v2.4.1.0) was sufficient to massively corrupt the ext4 filesystem on /data every time I did that (based on looking at the output of "e2fsck -f -n" in TWRP). After cleaning things up (ugh - recreating userdata ext4 from scratch means shuttling everything back onto the tablet again) I booted into the (stock) OS, and restored the same tar file into /sdcard as an unprivileged user - and no problems. No clue how/why that would happen, as tar files contain no inode information; but it suggests that there is some strangeness in the way that that emulated /sdcard mount works when a root user writes things... at least in the TWRP version of things. Very bizarre indeed.
Suffice it to say the whole exercise blew away a massive chunk of my time, even though I'm comfortable with this kind of stuff (I have used *nix systems for 30+ years). I can only imagine how folks with less experience feel when they get into a jam.

is there any alterations in ghrese steps for CWM users? I too am having this problem after installing a stock image friom the same sources as posted above, but i used onw of the nexus 7 toolkits to help asist me with this.
Thabnks, i am leaving for a trip tomorrow, so i was sorta shpcked to see 6 gb of storage on my device.

Well, given that you need to rebuild the filesystem in the userdata partition, you may not have enough time to work on this tonight, as it means getting everything worth saving backed up to a PC, and then transferring it all back after /data is rebuilt (back to the size that it should be). At that point you can either boot the "factory reset" OS to push your backups back to the tablet, or push them with adb & the recovery running so you can restore the backup before the first time you boot.
You saw how long the TWRP post was; can't say I want to do the same thing for a CWM version. Nor do I know even the first thing about any "toolkit" or what their operational hazards are.
But basically, the bottom line is re-building the /data ext4 filesystem from scratch. Even though TWRP has "mke2fs" & "tune2fs" utilities in it's ramdisk, it appears that they use a custom-built "make_ext4fs" utility for rebuilding ext4 filesystems. CWM probably has something similar - maybe a "format data" menu pick/button or something that sounds like that.
If you think you have enough time for this, you could perform the format using fastboot, as in:
Code:
fastboot format userdata
bearing in mind that this wipes EVERYTHING in /data including the psuedo-SD card (just as will any other procedure which rebuilds /data). So, if you make a Nandroid backup before starting this process, make SURE you've got your backups in a safe place off of the tablet before the format occurs.
Not having an external SD card on the N7 sure makes everything like this a pain in the a**, especially when it's potentially 20+ Gigs of stuff to move around.
good luck

I had to pull my CWM backup (however, doing a format data/cache using CWM didn't fix it). Eventually, the fastboot command fixed it. However, now when I try to transfer files over MTP/USB, it fails on the Internal Storage. So I am not sure why it is complaining. It doesn't give me an error, it just says the device has stopped responding, even though it is still listed and I have folders that are accessbile.
I guess I will just have to use adb push

So where can u find the ext4 file to delete? I did this once, it was a while agao but i need to find it
fixed on my nexus 7 but not sure what happened
thanks to you guys I solved my problem, same thing after installing a stock image from google i got 8gb of storage instead of 32. I did format data on CWM and than i got all of the storage back...i was really worried of not finding a way to solve this a big thanks to you guys.
In case u have the same problem you need to do format data on CWM and NOT wipe data/factory reset.
-----------------------------------------------------------------------------------UPDATE---------------------------------------------------------------------------------
The same problem happened again, i was not worried I did everything i did the first time but for some reason this time nothing got fixed...so after trying many things i asked myself "well what happen if I do not flash in my device the stock userdata after i erased them with the command >>fastboot erase userdata<< ?"
I tried and apparently it solved the problem i had all of my GB back. A little bit scare because during the boot in while i was on the image of the nexus logo (the X with four colors) it went back to the google screen (that one that appears when you turn on your device) but than it kept going normally. I did this two times first flashing in the stock stuff of the 4.1.2 of android and than with the 4.3 version (stock images downloaded from google)
Here the list of commands I used:
fastboot erase boot
fastboot erase cache
fastboot erase system
fastboot erase userdata
fastboot flash boot (I flashed the boot image of android 4.3)
fastboot flash system (I flashed the system image of android 4.3)
For the 4.1.2 I did the same except that i flashed in the userdata image of the 4.1.2 version I turned on the device to check the space on the settings and than i came back and used >>fastboot erase userdata<< and than turned on the device to check if there were some issues but it worked and the storage was back at full size.
I ask to someone a little bit more skilled than me to explain better what happened, and what I really did, because I'm really not sure about this I mean why not flashing the userdata image that came with the full pack from google is not creating problems and flashing it makes my device loose space? I would like to understand more about this.
Thanks bftb0 for this excellent working solution.
My Nexus 7 recently wouldn't boot (bootloop after a power off for no good reason...) and I used the Nexus Root Toolkit in force mode to put 4.4 on (I was on some older version to keep Stickmount working as it didn't work straight off the bat with new Androids). I had to use force because my bootloader is 4.18 I think and the update procedure via the Root Toolkit threw an error about bootloader version. 4.4 appeared to go on fine with force. I have no idea how to update the bootloader. Just playing with GPS apps today and putting maps on and found out I couldn't do it due to lack of space. Found the box for my Nexus 7 as I wasn't 100% what size I had but thought it was a 32G... Your solution worked fine. I didn't have to move the TWRP backups, just copied them over MTP and TWRP found them.

Also manufacturers advertise memory in base10 the decimal system so 1MB =1,000,000 bytes but computers don't work like that they operate in base2 the binary system so 1MB is actually 1,048,576 bytes. This is the brainchild of marketing gurus who think people can't understand binary.
On average for every GB advertised in base10 you get on average 70 mb less

Sorry for the slight necro
The same thing happened to me: coming from a custom rom and installing Nexus 7 4.4.4 factory image my 16gb device only showed 6.58gb total.
So i locked the bootloader (using WUG's) and unlocked it again. Result: it now shows 27.58Gb TOTAL SPACE LOL... I tried doing the data wipe in TWRP and i'm all out of ideas...
Anyone?
Hello. After from some mistake, I formatted my internal storage via twrp. Now I want to recover the data which I had. The bad is that the device is connected to pc as MTP & NOT as Mass Storage so that to use some data recovery to get the lost data. I tried MTPdrive which is to convert the mtp to mass storage but not any result. I tried Mobisaver (Easeus) which is for recovering data from internal drive but appears the message error that can't get the root previlidges even if my mobile is recognised as rooted. Also I used the dr fone recovery but for similar reason with above it can't scann deep my device. The only solution which I have found but it is difficult to try it because it needs unix commands so that to get the internal storage as raw image & after to convert the raw to vhd & after to mount it as drive so that to been scanned via data recovery like recuva which is given in here : https://howtorecover.me/data-recovery-internal-storage-android-phone-guide#raw or similar : https://roubert.name/joakim/androidfilerecovery/
The bad is that in these methods the unix commands are unclear & the most times you will get some error in the running of commands or the instructions will be unclear. Also I tried Partitions backup (apk) which can dump the internal as raw but althought has the option to save the dump image to external storage, it saves only to internal which is irrational because my internal storage is 64 Gb & can't be saved all this as img file to my internal due to low capacity & for some unknown reason the external storage save can not be selected. Does it exist some way to get the lost data back of internal storage or to connect my Mi A1 as mass storage or to dump my internal storage as raw ? Thanks.

I followed this method and I was able to successfully dump my phone internal storage data into raw. But please be aware that successful recovery of your data from the dump file is not quaranteed.
Please read carefully the instructions and always make a backup before u proceed.

In the beginning writes "This method does not seem to work on newer phones that apply TRIM or some other type of partition clearing implementation. If anyone has recovered their data on a device newer than Android 4.3 please pm me and let me know." Does it mean that it is for older mobiles or you did it for Mi A1 with android 8.1 ?
