Completely Ruined my Partitions - Need Glow Restore IMG

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.
The script nookpart.sh is in my signature.

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.

Some easy instructions here http://forum.xda-developers.com/wiki/BN_Nook_Simple_Touch/Installing_ADB
And search for a file named "ADB + Fastboot + Drivers.zip" in the forum.
With all that you can get ADB running in a Windows machine in no time.

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.

EU bug fix guide!!!!!!!!! actuall fix NOT external sd workaround

ok so first boot into recovery make a nandroid than remove your external sdcard and download the odin flashible semaphore kernel for vibrant from semaphore.gr (be sure its the newest one) now go to download mode and flash that. as soon as its done it will reboot and you want to reboot into recovery. next plug it into your pc while still in recovery mode and run the adb devices command to be sure your devie is connected and recognized now go to adb shell and run these commands hitting enter after each line
parted /dev/block/mmcblk0
print
rm 1
rm 2
and what that does is removes all your partitions so just do rm X for each partition number you have puting a space between rm and whatever number you have. now go back to download mode and flash Eugene_2E_JK2_Froyo.tar heres a link to download http://d-h.st/VGX. and your going to go through the process of everything flashing in oden. besure to flash that as pda. than you will be at stock recovery and you will get the ant mount bla bla bla or if it boots straight to the rom to thats fine. and now go to settings and format internal sdard under storage settings your external sdcard should still be REMOVED now after thats done reboot and you should have a fully working vibrant. this fixed mine. if it doesnt work tell me hope i helped

also works with captivate and facinate too!!

First and foremost, thanks for posting this guide.
I'm gonna' run through this right now. Wish me luck. :fingers-crossed:

if it doesnt work tell me

So I attempted your guide...and the good news is that i was able to access recovery right after flashing the sephamore kernel .tar in odin. The bad news on the other hand is that I was unable to execute the adb shell commands you've listed in your guide. I got an error stating that "there is no such file or directory". So I skipped the commands and flashed ICS passion v13 and it booted!!! but only to be followed by the dreadful "Encryption Unsuccessful" screen lol.
I took a screenshot of the EU screen by pressing the power button hoping to upload it here for you guys to see...but this is where things got really strange. So I removed the battery, sdcard, and inserted the sdcard into my pc to look for the screenshot and it wasn't there!!!. So this means that the screenshot was saved to the internal memory. I can sense I am getting closer to fixing my old vibrant.
Stay tuned

Like Merio I, too, flashed the Semaphore kernel via ODIN.
But unlike him, I cannot access Recovery.

Try the following commands in adb.
adb devices
adb remount (might fail but don't worry)
adb reboot recovery

i use devil kernel to access the recovery.....but at 'parted /dev/block/mmcblk0' this step i got the same as merio90

Yeah devil or semaphore. Semaphore is just easer to boot to recovery

Update
Well after 5+ hours of countless rebooting and flashing/modding I have failed to bring my vibrant back to life. However... I was able to go real deep into the device's storage hardware both internal and external(sdcard) and discovered that the internal storage is alive and functioning. In other words it is not hardbricked or physically damaged as a result of the EU bug...it is just corrupted and unable to mount.
Furthermore I attempted several times to create or recreate the partions on the internal sdcard but It just would not allow me to do so. By the way this is all done using the "parted /dev/block/mmcblk0" command(s). Hopefully there is some one who understands how to use this "parted" function in adb as this can be a very useful tool in restoring our devices back to normal.
Here are some helpful details I have learned in the process of all of this...
For those who are having trouble entering the commands in the guide make sure you are entering a space in between "parted" and "/dev/..."
At first I forgot to enter the space and as a result I got an error reading "no such file or directory" so make sure to include the space.
adb shell >>>>>>>>>>> Don't forget to enter this command first...won't work otherwise.
parted /dev/block/mmcblk0 >>>>>>> mmcblk0 is the external sdcard (at least in my case it is) while mmcblk0p1 is the internal sdcard (in my case)
print >>>>>>>> This command list the specifications for the storage device mmcblk0 along with some other useful information.
rm 1 >>>>>>>> This removes partition 1
rm 2 >>>>>>>> This removes partition 2 (if existent)
While still using the "parted" function in adb shell you can simply type "help" and it will give you all the details on how to use this useful tool.
Well I guess that is all I can say for now. Thanks again cannondale...your guide was certainly helpful and allowed me to learn more about this EU bug and how it is "bricking" our devices. This is certainly a step forward in the right direction...I am confident we will have this EU bug squashed pretty soon once and for all.

Thanks manu...this isn't the first time I've read your thread concerning the EU bug. I simply ignored it at first because it seemed a bit too technical at the time. But now that I've gone through this guide cannondale has provided your thread certainly makes more sense. I'll get back to working on this case soon.

So has anyone besides the OP gotten this to work?

@Merio90 ... Just wondering if you made any further progress on the matter. Thanks to cannondaleV2000 for opening these doors and to Merio90 for the detailed posts (esp. concerning syntax). Very interesting thread.
I gave it a go but no nookie for me. In a nutshell, GNU Parted only appears to work on the external sdcard (mmcblk0p1) and not on the internal. Here are my results (after numerous attempts).
RECOVERY ACCESS
My observations flashing Semaphore JB .tar's (after a fresh Odin to Eugene_2E_JK2_Froyo.tar).
* Hangs on Semaphore splash: 2.9.21v, 2.9.15sv, 2.9.12sv.
* Recovery access successful: 2.9.21sv, 2.6.5v, 2.5.0sv

Using /dev/block/mmcblk0p1
Welcome to GNU Parted! Type 'help' to view a list of commands.​So ... it's rather curious that cannondaleV2000 actually had access to his mmcblk0 while others weren't so lucky. That's the obvious key to using the parted functionality on the internal sdcard. If only we could break through that road block ... and return to the internal sdcard holy grail!! Any thoughts?

@yosup
No I have not made any progress other than the info I have already posted. My vibrant is no longer my daily driver, my Galaxy Nexus is... so my apologies for not giving this issue a higher priority.
I was only able to "fix" my vibrant to the point where I was able to use the SD card swap method many of us have attempted. In case you were unaware I had to take some extra steps as my vibrant was totally screwed up. It was unable to read either internal or external sdcard so that was an obstacle I had to overcome and that's how cannondale's guide was able to help me. So as of today no progress has been made...I haven't really worked on this problem in quite a while now so any progress has come to a halt for now...until someone comes up with a new guide On another note, the good news is that I have yet to encounter the EU bug on JB 4.2.2 (AOKP M1). So those who are using the sdcard swap method you should try a JB ROM...they seem to not be vulnerable to this EU bug.

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,
Paul

The logs= errors displayed on the screen provided by the interface you use to flash the rom (recovery, computer...)

Does this help any?

do I need to create a partition? Never get more details despite the tease.
Thanks,

First -
Try and download a different (NEWER) TWRP. Re-flash TWRP. Try again
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)

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.

I am not familiar using ADB pull. Tried using a root file manager to access the log but don't see.
Greatly appreciate your help, let me know what other info I should paste.
Thanks,

Please Help How fix Unable to mount internal storage

Hello everyone,
Please Help me to fix this issue
TWRP shows E: Unable to mount '/cache'
E: Unable to mount '/data'
E: Unable to mount '/system'
E: Unable to mount '/cache'
E: Unable to mount internal storage
I have twrp v2.5
Actually, I am trying many solutions but nothing change

Hi, pal. I have the exactly same problem these days. On my opinion, when you have made wipe and wipe dalvik cache, you just deleted the system folder and data. I did same thing, now I'm stuck! :Д When you are trying to change the firmware, is the logo pictures changing for you every time you flash any other .zip file? We' are now complete lost man. Is your USB working like mine where PCs not detecting it? I think they've launched this kind of firmware only to destroy our device, so we can buy a new one. That's the idea. Go to the service and repair center of Lenovo and ask them for help! I wrote them down before a while, now I'm waiting for the response. We have left only two or three possibilities to flash the Rom with the Terminal in the Recovery. But if your PC recognizing the drivers, you will manage to flash the Stock 4.2.2 Rom with Flash tool , otherwise you are stuck too! I have no idea how to flash it. I can give you the terminal commands for you, which are hard to find, but you and me, we need the proper .img files for the flashing procedure. Go to the 4pda forum and ask for help, if you find any solution, come back here telling it and for me. There's a possibility, but it is difficult to create a proper .zip archive, because I only know that we need those folders and files: meta folder- updater-script, logo. bin, lk.bin, boot.img and system.img.
But when I insert the commands there, I don't know how the whole process must be working, something is happening there. The problem is that one of those lines did not work for me. Those are the commands for flashing any Rom with the terminal in the recovery. But first you must see if the PC is installing your drivers properly, open device manager and look for the drivers on the internet and try to install them. May be you have a working USB port, so there's no problem, just flash the stock rom with the Flash tool. But if it is not working as it is here, no other possibilities left, my boy! The only one left or two of them : Flashing the device either through fast boot mode or adb sideload, but you must install those drivers so PC can find the device. Well, you can always do this at your own risk from the terminal.
Oh, I forgot, those problem came when we deleted fstab file for our device.

Flashing firmware through the TWRP terminal commands:
dd if=/external_sd/system.img of=/dev/block/mmcblk0p6 (for the memory ROW+ ) or
dd if=/external_sd/system.img of=/dev/block/mmcblk0p5 (for CN+ memory)
dd if=/external_sd/boot.img of=/dev/bootimg
dd if=/external_sd/lk.bin of=/dev/uboot
dd if=/external_sd/logo.bin of=/dev/logo
First, system.img must be converted to systemEXT4.img, then flashing it and you need to have a systemEXT4 in the .zip archive. But I think my system folder is deleted. :Д
simg2img /external_sd/system.img /external_sd/systemEXT4.img
Good luck to you! According to me there is a space after the dot and it must be like this: system. img, boot. img. But not sure!

Hi again. Tooday It occurred to me where our problem may be came with the tablets. When we flashed a custom Rom, we put it for the wrong MTK processor. Ours is MT8389, not 6589. The stock roms are too for the MT8389 according to me. We flashed a wrong Rom. Now the tab must be formatted somehow either through some commands from the terminal, or USB port and path to the USB must be repaired. Then, flashing with the Flash tools is our only option left! Sorry! );
They killed our device on purpose with the Custom rom. Do not flash them any more with such Roms.

"Failed to mount '/system' (invalid argument)", Help translating tech talk

To be quick, I have a very specific error in all TWRP versions on LS997 that won't let the system stay mounted while flashing roms, "Failed to mount '/system' (invalid argument)".
I believe I found a fix for it in a dead reddit thread, but I can't understand how to do it on an LG v20.
Help is much appreciated.
It reads
"for anybody that stumbles upon this thread: I got it working by using a parted binary and mkfs.ext4 binary.
I removed the partition and added it again with parted, don't forget to name it correctly. And then I reformatted with mkfs.ext4. Those three links might help:

I’m also looking at the thread, and the miui link is stale because miui cleaned their forum.
I tried erase data (entire partition). I tried wiping system data cache, no matter what I did it was error 7 or unable to mount system.
I’m suspecting it might be which kdz I used for the downgrade but honestly it can’t be the case because I did this before 2 months ago and it was ok, now I can’t do anything.
