[Q] Mounting NST Backup Images in Linux.

Hi all,
So I've made a few backup images of my nook and want to be able to access the files on there without problems. I'm not the most knowledgeable Linux guy but have a Kubuntu VirtualBox image lying around for when I decide to compile Rockbox and such. I've also got Cygwin installed, but never expect it to do anything correctly, really. I haven't really come across any Windows tools that'll do the trick for me, so I want to know what I'm doing wrong with my parameters for the 'mount' command in Linux. What I really want right now is to get into the the system partition (#5).
Now I don't really know how to use mount beyond a little bit of googling, so I likely missed something here, but anyway, this is what I did:
I ran
Code:
fdisk -l nook_1.0.0_backup.img
and got this:
Disk nook_1.0.0_backup.img: 1958 MB, 1958739968 bytes
128 heads, 32 sectors/track, 934 cylinders, total 3825664 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

nook_1.0.0_backup.img8 2150432 3792895 821232 83 Linux​
I multiplied 577568 by 512 to get an offset of 295698432, and knew that the system partition uses ext2 by running 'mount' in the nook's shell, so then I ran:
Code:
mount -o loop,offset=295698432 -t ext2 nook_1.0.0_backup.img /media/n2e
and keep getting this error message:
wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases, useful info is found in syslog - try
dmesg | tail or so​
trying dmesg | tail yielded this gibberish:

I also tried using dd to extract that partition (which I also did correctly if you go by file size, which is identical to the file size listed when I extract it via 7-zip in Windows) and then tried to mount that, but got the same message. I'm thinking this is all a simple syntactical error...any ideas? roustabout? ros87?

Wait, so this piece of software does the trick in Windows:

But I'd still like to know how to mount correctly.

Double posting will make you quite popular with the moderators,.. not!
I answered you here.

very simple bash script:
Code:
#!/bin/bash
if test $# -lt 2; then
echo "usage: $0 [image] [mount point] <partition number>"
exit
fi
if test -z $3
then
number=1
else
number=$3
fi
mount -o loop,ro,offset=$(parted $1 unit B print | grep "^ $number" | sed "s/\s$number\s*\([0-9]*\)B\s*.*/\1/") $1 $2

Is my Nexus 7 dead?

Okay, I have fastboot and ADB, the only way to get into recovery is through wugs toolkit. I have pushed a ROM to my phone but is says FAILED when I try to flash.
it says TWRP v 2.4.1.0 errors saying

If I use fastboot to try and install recovery, boot, bootloads, or anything it fails as well.

Any help is much appreciated.
Now this is my 4 year olds tablet and we woke up the other morning and it just wouldnt boot anymore. I did unlock it just for fun when we got it a couple months ago but I dont know why it would just not boot into the OS after two months.

In the situation you are in, you should NEVER use fastboot to attempt overflashing of the bootloader. All else, OK.
Try soft-booting (not flashing) a more recent recovery, e.g. TWRP 2.3.x.x or 2.4.x.x
pull it down to your computer & verify it's MD5 sig, then
fastboot boot recovery-image-name.img
If that works, via "adb shell" (once the recovery starts, ADB should work), see if you can do a
# mount /system
# mount /data
if these succeed, that means that each filesystem is OK. (Already mounted counts as a success) If it doesn't you will have to use the mke*fs tools located in the /system/bin or /sbin folder of the TWRP boot to re-initialize the /system, /data partitions as necessary.
My guess though is that if the device failed before all this happened, things might not be fixable.
If you can't even soft-boot a recovery - let us know what error message occurs.

I tried to mount system and data in recovery and it didnt work...i tried cwm 6.0.2.3 and twrp 2.4.1.0
I see files in /sbin folder in recovery, how do I use those files?

well, if you are using the touch version of TWRP the "format data" command rebuilds the filesystem (after nuking it first) with mke2fs.
The command line for mke*fs can have lots of arguments, and off the top of my head I don't know which device plumbed into the kernel is the correct device.
Gimme a minute, I just did a factory reset on my tablet.
But yeah, if you are doing stuff manually from the command line with adb, you will be using the executables in the recovery's /sbin or /system/bin or /system/sbin (e.g. the mke2fs command).
Hang on, gotta check something.

with your recovery running, type the command
mke2fs --help
you should see something like this:

I believe the commands you will want to use are something like
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p9
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p3
for /data and /system respectively. Give that a roll, power off the device, reboot into the bootloader, and then soft boot into your recovery again and see if /data and /system can be mounted

did you try re-creating those filesystems?
probably you should add /cache in there for good measure
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p9
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p3
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p4
It is possible that when you are in fastboot mode (bootloader), the bootloader does not rely on having intact filesystems and performs a wipe and re-creation of each filesystem before it unpacks those (sparse) ext4 image files onto the targets.
But what I am suggesting above will give you more visibility into what is going on than using fastboot.
Given that you don't know where the trouble is, as I said before you should not be doing ANYTHING at this time which overflashes the bootloader - including installing full factory images.

It looks right for the stock kernel, but stuff gets plumbed into the device tree differently depending on kernel.
Which recovery are you using?
you could try the "by name" devices:
mke2fs -T ext4 -m 0 /dev/block/platform/sdhci-tegra.3/by-name/UDA
mke2fs -T ext4 -m 0 /dev/block/platform/sdhci-tegra.3/by-name/APP
mke2fs -T ext4 -m 0 /dev/block/platform/sdhci-tegra.3/by-name/CAC
(UDA -> /data, APP -> /system, CAC -> /cache)
BTW - if you haven't figured it out by now - you get "out of" the remote shell by typing the command "exit". You'll see the prompt change back to the Windows command prompt "C:\blahblahblah>"
Hmmm - those "by-name" entries are symlinks back to the same device names I gave you originally. Well, on the stock kernel anyway.
what does the command "ls -ld /dev/block/*" get you (on the adb shell) ?

Send me a link to the place you downloaded your recovery image from, I can soft boot it and take a look.
either that or do a "cat /proc/partitions" and let me know what the output is.

Skyler - we may well have stumbled onto the problem. I booted a couple of different recoveries, and they mostly plumb devices into the same device nodes in /dev/block.
What that suggests is that your partition table got mangled.
If it turns out that this is the case, your question "Is my Nexus 7 dead"? can probably be answered in the affirmative - until someone clever reverse-engineers the Nexus 7's APX mode.
There is a way that you can check this - with the "dmesg" output from your soft-booted recovery.
From the windows prompt, do this:
- soft boot the recovery (so it has been fairly recently booted), and once the ADB link comes up, do this:
C:\ugh> adb shell dmesg > dmesg_out.txt
this (the file "dmesg_out.txt") will have the kernel boot log in it. In an orderly boot, you would see something like this:
Code:

and further, the command

should display something like this:

If you are missing a bunch of partitions, you have a problem with the eMMC Flash memory chip that is not currently correctable with tools in the wild.
Is that what you see - errors in the dmesg log, or a lack of partitions in /proc/partitions?

Skyler - we may well have stumbled onto the problem. I booted a couple of different recoveries, and they mostly plumb devices into the same device nodes in /dev/block.
What that suggests is that your partition table got mangled.
If it turns out that this is the case, your question "Is my Nexus 7 dead"? can probably be answered in the affirmative - until someone clever reverse-engineers the Nexus 7's APX mode.
There is a way that you can check this - with the "dmesg" output from your soft-booted recovery.
From the windows prompt, do this:
- soft boot the recovery (so it has been fairly recently booted), and once the ADB link comes up, do this:
C:\ugh> adb shell dmesg > dmesg_out.txt
this (the file "dmesg_out.txt") will have the kernel boot log in it. In an orderly boot, you would see something like this:
Code:

note that it detects 9 partitions
and further, the command
C:\ugh> adb shell cat /proc/partitions
should display something like this:
Code:

Well, that explains that. Some bootloaders (usually S-OFF engineering bootloaders, not public release bootloaders) allow re-partitioning if the device gets completely stuffed up, but generally the public release bootloaders do not - which explains why flashing the factory roms from fastboot mode was failing - it too needs to read the partition table(s).
The Tegra 3 has this mode called "APX" which is similar to the "download mode" on Samsung phones where the PC application "Kies" can be used for manipulating Samsung phones at a very low level, including things like repartitioning the basic flash filesystems. It's what makes those Galaxy phones nearly impossible to brick, short of hardware failure.
Until we have tools for working in APX mode though, situations like yours are a dead end even for rooters.
RMA time? I don't think it was anything you or the 4-year old did by the way - I would engage with Asus/Google with a completely clear conscience.

I called and I am doing an RMA, Ill be shipping it off tomorrow or the next day. I will post back if they actually send me another one. Google was amazing by the way, a real pleasure to deal with. I appreciate all the time you and bradman put in tonight to help me figure this out. I REALLY REALLY REALLY appreciate your time and efforts! This has by far been the best experience I have had on any forum! You guys are awesome!

Well they received my device. Waiting to see if I get charged or get a new one.

[Q] Stock NC bricked, acts as if theres no internal memory.

Hi guys, Total Noob here.
I've been reading through the forums over the last week and am still at a total loss. Despite trying numerous things, nothing I've tried has worked.. If anything, I'm afraid I've made things worse.
The back story: The NC we have is a newer one purchased *just* over a year ago, given to my 10yr old daughter as a bday gift. It's never been rooted or modded in anyway whatsoever. Two weeks ago while she was playing a game on it, it locked up, and wouldn't power off. We let it sit for a couple of days for the battery to drain. After that, the battery wouldn't charge, the NC would not boot and the cable indicator stayed orange. So I purchased, and replaced the battery. I let it sit overnight after replacing the battery, and we got a green light. On boot up, it would hang at the 'N Screen', and do nothing more.
I tried running the NC recovery, but that only resulted in an "INSTALL FAILED" error message, and that was the last sign of life to have been seen coming out of the NC.
At this point, it will only boot off the SD card, (currently using an 8gb with CWR 6.0.1.2), I no longer get even the 'N screen' anymore. I've tried leapinlars partitioning and formatting .zips, I've tried every stock image I could find, but the result is always the same. No partitions are mounted, and nothing but errors are generated.
I've tried connecting through ADB, but 'ADB DEVICES" only returns:
Code:
C:\android-sdk-windows\platform-tools>adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
0000000000000000 recovery
...and nothing more.
Since this NC is for my daughters use, I'm really not interested in rooting or opening up android for her, I'd really like it to be nothing more than stock, but at this point I'd be grateful just to see some sign of life come out of this thing. All help would be greatly appreciated.
I hope I've provided enough info, anybody have a clue whats going on here?

You need to type
fdisk -l /dev/block/mmcblk0
in ADB. That will show you the partition structure of emmc. I suspect your cylinder/head/sector count is messed up. That is why my zips appear to work, but do not.
Report here the output of the command.

Thanks for the suggestion leapinlar, I assumed fdisk -l would show all disk info by default if a specific disk wasnt specified. For some reason when I plugged the NC into the USB port today, My Win7 box did not recognize it or want to reload the drivers the same way it did last night, and I was unable to connect to the NC through ADB.
I will try to figure out that later on, or try to use ADB through my Fedora box when I get a chance. In the meantime, I once again tried your repair-partions.zip and copied CWM's error log, which is pasted below. Hopefully this gives some insight:

/dev/block #

Strange, today when I opened adb, it appears that some of the entries in /dev/block have changed. mmcblk0p1 is gone and replaced with mmcblk1p1.
Yesterday I saw this
Code:
/dev/block # ls
ls
loop0 loop4 mmcblk0 ram1 ram13 ram3 ram7
loop1 loop5 mmcblk0p1 ram10 ram14 ram4 ram8
loop2 loop6 platform ram11 ram15 ram5 ram9
loop3 loop7 ram0 ram12 ram2 ram6
This is what I see today:
Code:
/dev/block # ls
ls
loop0 loop4 mmcblk0 ram0 ram12 ram2 ram6
loop1 loop5 mmcblk1 ram1 ram13 ram3 ram7
loop2 loop6 mmcblk1p1 ram10 ram14 ram4 ram8
loop3 loop7 platform ram11 ram15 ram5 ram9
/dev/block #
If my understanding is correct (and it's usually not) the "P1" indicates that this is "partition one" on the "mmcblock one" device. (or 'disk'). I'm further assuming that of the two devices shown (mmcblk0, and mmcblk1) one of them is my 8gb microsd card, and the other is the NC's internal 8gb memory. Which makes me wonder why yesterday's "ls" did not show both devices. Also makes me wonder what the 'p1' partition is, which disk it's really on, and why it appears to have moved.
I took a look at the geometries of the disks and the partition using fdisk again, I dont know what I should be looking for here, and dont know whats relevant and what isn't. I can see I have two disks of slightly different sizes, and a mystery partition of some sort that doesnt seem like it should fit on either of the two disks.

Ok. I feel real stupid, obviously the mmcblk1 device is the sdcard and the p1 partition on it is the fat32 partition on it. Still leaves me wondering what happened to the geometry on the internal memory. CHS looks way off. shouldn't it be more like that of my sdcard?
*** Second Update***
I'm pulling my hair out here. I tried to correct the CHS values...no love there, even after rebooting it remains unchanged.
Code:
~ # fdisk -C 965 -H 255 -S 63 /dev/block/mmcblk0

So it appears my partition table has been written successfully. I just need to create partition 8. ... before I do that, I will reboot the NC to make sure the partition table is persistent...
Code:
fdisk -l /dev/block/mmcblk0
Disk /dev/block/mmcblk0: 7734 MB, 7734296576 bytes

Disk /dev/block/mmcblk0 doesn't contain a valid partition table
...and that's a big fat fail.
At this point, It looks like my only option to ever use this NC again, is to have a stand alone bootable sd card. If anybody has a suggestion, please throw it my way.

Do either of these things indicate anything of importance that could potentially be of help?
1) 'adb devices' lists the Device ID as "RECOVERY"
2) The internal memory seems to be in a 'read only' mode of some sort.
The last time this NC did power up under its own free will, was when the stock recovery was being attempted - and crashed.

Your CHS (cylinder, head, sector) settings are wrong. It should be 255 heads, 63 sectors/track and 965 cylinders. You need to run fdisk CHS to fix it. You need to type the following command in ADB shell.
fdisk -C 965 -H 255 -S 63 /dev/block/mmcblk0
Then do an
fdisk -l /dev/block/mmcblk0
to see what you get.
If the CHS is right you can do my 145678 repair and format. I don't know if the p2 repair will work though. If not, I may be able to help.

Thanks for your help, I really do appreciate it.

I may be crazy here, but what are the odds my NC does not have the same emmc chip? This thing sure acts like its fallen victim to the 'brick bug'. I cant seem to write anything at all, Tried creating new partitions with parted, no go. Even tried overwriting the mbr with dd if=/dev/zero of=/dev/block/mmcblk0 bs=512 count=1 and it didnt even touch it.

I may be crazy here, but what are the odds my NC does not have the same emmc chip? This thing sure acts like its fallen victim to the 'brick bug'. I cant seem to write anything at all, Tried creating new partitions with parted, no go. Even tried overwriting the mbr with dd if=/dev/zero of=/dev/block/mmcblk0 bs=512 count=1 and it didnt even touch it.

I have had SD chips that became ready only by some mysterious means. It is possible that your emmc has done the same. In fact, one other user said that happened to his emmc.

Alrighty then, I confirmed this much at least:
with
Code:
dmesg | grep mmc0
The emmc chip in my NC is the Samsung M8G2FA, which is prone to the "Brick Bug", and from the little I've read on it so far, the bug is brought on merely by wiping the cache partitions clean. I got me some more reading up to do...

Today, I called BN tech support for the second time in a week, after visiting the local store to see if anybody there could offer up assistance. Long story short, because our NC was just out of warranty (by three weeks) they did offer to exchange it with a 'certified pre-owned' . When that comes in, the very first thing I'm going to do is see what memory chip it has in it, Evidently just trying to do a 'hard reset' and run the stock recovery bricks the M8G2FA EMMC. However, I still don't know what caused our NC to lock up in the first place. I guess at this point, that's moot.
leapinlar, I've read through many of your posts, although I couldn't fix my problems, you were instrumental in keeping me sane. ... well, depending on how loosely you define sane,

Internal memory not working: host doesn't support card's voltages

A friend of mine got a new tablet and gave me his older S7-105.
He tried to upgrade to android 4.2.2 and repartition internal sd to have more internal space, and somewhere in the process his internal sd card seems to be dead.
After a couple of days reading this and some other forums, I have finally been able to install PAC-man 23 JB 4.2.2 rom, but all without external sd card. I tried to access the internal sd card from all systems: 2.1-upd1, 2.2.2 and 4.2.2, but no success.
I have also tried downgrading and zeroing the mbr with dd if=/dev/zero of=/dev/block/mmcblk0
but it just creates a 204mb file in /dev/block/mmcblk0 as /dev/block/mmcblk0 doesn't exist.
Now I have PAC-man 23 JB 4.2.2, and I have manually installed parted binaries.
This is what I get in dmesg related with mmc.

"host doesn't support card's voltages" seems to be the main error... this looks as a kernel config error.
My external 8gb SD card is properly detected (mmcblk1).
It has two partitions, mmcblk1 and mmcblk1, but app2sd is not working. /sd-ext is mounted. I'll have to study a bit more.

Could someone help me revive my internal sd?
I'm not sure but it might be a hardware problem.
It could also be some kernel problem, as I didn't see those mmc errors in dmesg with 2.1 or 2.2.2. (I coudn't access internal mmc anyway)
what other kernels can I try?
Thanks just for reading this long post!!

I'll need to install or build a kernel with CONFIG_MMC_DEBUG enabled to see what might be going on with more detail.
Which kernel sources and .config do you (devs) recomend to use for s7-105 on 4.2.2?

I just installed 2.1-upd1 from dload in external sd card.
After getting root and installling busybox and sshdroid I see the same error in dmesg:

host doesn't support card's voltages, same error than with 4.2.2
I have noticed that mmcblk0 and mmcblk1 are opposite than they were with 4.2.2!!!!

Maybe someone could post a full cwm backup of a clean 4.2.2 system with working internal and external sd?
I can create a ftp account to upload it to my cloud server, if needed.
I think there might be something wrong with some of my config files, which doesn't get overwritten when I flash a rom.
Some settings are kept, as language, so maybe the wrong partition information is passed from one installation to the other.

Contents of /system/etc/vold.conf are completely different in android 2.1, can someone post his /system/etc/vold.conf ?
This is mine:

It sure looks to be hardware related but hope I am wrong and you get your memory back!

I've found a way to access "dead" internal sdcard. need help to make a permanent fix

I've found a way to access "dead" internal sdcard. need help to make a permanent fix
I think i've accidentally discovered a way to restore access to dead internal sd card.
And sorry for my broken english
You can skip the story till the "*Punchline*"
So i got a i9000 to try and save.
He has no /dev/block/mmcblk0 when the microsd card was out and when the microsd was in, the microsd was the mmcblk0 instead of mmcblk1
So i've did the regular fix, made 2 partitions on the microsd. one for the usb storage and one for the /data
The device got back to life but still without the internal sd(as expected).
On /dev/block he has only the mmcblk0 via recovery or regular boot (Using adb shell)
Then i had a problem, the camera won't work. its had that message "insert sd card before using the camera"
And on logcat you see that error: "E/CameraStorage( 3950): Failed to create /storage/sdcard0/DCIM/100ANDRO"
Although the mmcblk0 is the microsd now, and there is no mmcblk1 the ROM (cm11 on that case)
mounted the microsd usb storage partition (mmcblk0p1) on /storage/sdcard1/ and not /storage/sdcard0/
(The mount of /data and /sdcard are made via lvm)
I've tried to manually mount /dev/block/mmcblk0p1 on /storage/sdcard0/ - didn't worked (don't rembere the error message )
Tried link /storage/sdcard0/ -> /storage/sdcard1/ got some error about file system link
And when tired to mkdir /storage/sdcard0/DCIM got readonly file system error.
So i've wanted to switch between them via the lvm mount in fstab (I didn't really know how to do so)
On the using adb shell (on the rom, not recovery) i've edited the /fstab.aries
and commnted the lines that starts with "devices/platform/s3c-sdhci"
My final fstab.aries:

*Punchline*
Then i did "reboot recovery"
And on the recovery the internal sd card was back!!
i've managed to mount it and access the usb storage partition & data partition!
Code:
~ # ls /dev/block
dm-0 loop6 mmcblk1p1 mtdblock6 ram14 ram8
dm-1 loop7 mmcblk1p2 platform ram15 ram9
loop0 mmcblk0 mtdblock0 ram0 ram2 vold
loop1 mmcblk0boot0 mtdblock1 ram1 ram3 zram0
loop2 mmcblk0boot1 mtdblock2 ram10 ram4
loop3 mmcblk0p1 mtdblock3 ram11 ram5
loop4 mmcblk0p2 mtdblock4 ram12 ram6
loop5 mmcblk1 mtdblock5 ram13 ram7
And the microsd was pushed to be mmcblk1 as it should be.
The problem is that if you restart the device back to the ROM, the fstab.aries being overwritten and the the SD is gone again.
But if you edit the fstab.aries again and reboot directly to recovery you will get it again.

I don't know yet why that happening, maybe the voldmanaged/LVM mount configurations crashing the internal sd device on startup
But its looks like something that can be fixed!
I'll keep trying to fix that myself, but i'm sure there are gurus here that can do it!
Updates:
I'm copying the data from the internal sd to the micro sd and its have some bad blocks (not unexpected)
Code:

After the backup ill try to completely wipe the device & recreate the partitions
