[Q] Restore partition?

(Using the latest SDcard CWM. Tried using the latest CWM through RomManager)
So I finally got my replacement nook and straight out of the box, rooted it and tried to set it up to dualboot by using prep-dualboot-0.1 after using manual nooter 4.5.6.
When flashing the dualboot, I keep getting this error.
..
..
E:Error in /sdcard/prep-dualboot-0.1.zip
(Status 0)
Installation aborted.
So I thought I messed up somewhere with the partitions and had no space so I decided to look at the available space through the nook settings. For some odd reason, it says 1GB as opposed to 3.x GB or so which my defected nook had. I already tried reverting it back with remove-dualboot-0.1.zip.
Heck I even tried going into do ADB and doing rm -rf /* while in CWM but it really didn't fix anything.
How exactly can I fix my partitions?

So I actually found out that...when I plug the Nook via USB to my computer, two drives come up (There is no SD card in it). They're both unreadable with no indication the capacity. When I try to click on it, it ask me to insert a disk. I can't even format /data through CWR since it gives me the message "Error formatting /data".
So I'm guessing I messed up my partitions badly to the point where reinstalling stock FW or removing the dualboot with the removal zip won't help. Any suggestions? Is it possible to wipe the nook COMPLETELY and just remake the partitions via firmware?
_EDIT_
I was able to install the stock 1.2 update. Though the space available now says 1GB out of 1GB free now. How do I get the rest of the space back? =/

[Q] What did I DO to my beloved Nook!!!!

don't know if anyone can help but I am getting my butt kicked. I have tried all the steps mentioned throughout this post and several others to no joy. I was trying to update to CM7 a few days ago and my nook stopped working. It was something I saw on youtube. Probably shouldn't have trusted it, don't know. Now whenever I am CWM I get
e:can't mount/cache, recovery/log
e:can't open/cache/recovery/log
e:can't mount/cache/recovery/last_log
e:can't open/cache/recovery/last_log.
also when I try to format system and date i get error formatting data! and error formatting/system! I am using CWD 3.0.2.8 and I can't use ADB either. My computer will not recognize the nook in device manager.

M8, I don't know which version of your NC, but I do suggest NOT to use that version of CwM Recovery.
Get the 3.2.0.1 first and then we can start from there.

Thanks I have 3.2.0.1 downloaded.

What will work is putting eyeballer on an sdcard and reinstalling your rom.

eyeballer is the CWR 3.2.0.1 right? I tried that but no joy.

I just restored my NC after having boot loops, and failing to mount the SD after the latest CM9 nightly install. The only thing that got it to mount the SD I had the restore on was to put eyeballer's 1gb CWM 3.2.01 image on a Sandisk 4gb card along with a CM7.2 zip, and booting from that. Once that booted, I swapped cards and restored the NC from the card. IIRC, I had to do a few steps more than once, and did a full reset before booting from the image card. A real PITA, but I got my Nook back.

That is strange because I was having the same issues with my own tablet and I decided to format the SD card. When I did nothing was gone from the card... It just would not format in the device. I decided to try formatting it from my PC, and it would fail at the same time during formatting everytime. After replacing the card all of my problems were gone.

[Q] Can I have partitions that can be accessed from both NC Stock and CM7 on SD card?

Hi everyone!
I just got CM7 (latest stable release) installed on on external sdhc card. I have wifi issues with CM7 (and looking around the forums tells me that CM7 can be finicky with certain routers) so I would love to be able to use Nook's stock ROM (4.1.4) when I am having issues.
But, when I am on NC ROM, I don't see anything except the small boot partition on the SD and when I am on CM7, I don't get access to this boot partition. I am wondering if there is a way to either create another partition or make the currently existing partitions accessible on both ROMS so that I can share data between them.
I am a n00b without any Android experience so thanks in advance for your patient responses.

Look in my signature for a link to my tips thread. I explain there how to make the SD media partition available to both ROMs (item B3).

If whatever you have on emmc is rooted, you can manually edit it. If you have unrooted stock, then you need to flash the zip since without root you cannot edit those files manually. And I did mean item B3. Each item is a different topic, they are not steps. One topic does not depend on another. Just do B3 and no others if you want.

Yes, item B3. My mistake...
I should be able to do flash the zip from my current CM7 SD card's boot partition, shouldn't I?
So I put the update-stockemmc-vold-fstab-modified-for-partition4.zip file in the boot partition of the SD card, rebooted to Recovery mode and then booted to NC's stock ROM. NC is still using the tiny boot partition on the SD card as my external storage instead of the much larger CM7 partition. This was the same partition that was under 'My Files / Memory card' before I flashed so nothing has changed. I did this twice to double-check.
Am I doing this wrong?

Yes you are doing it wrong. You need to flash that file with a CWM card, not put in the boot partition of your SD. And since you did that, you need to re-flash your latest ROM on SD to correct your mistake. (I will edit my instructions to make it a little clearer that you use CWM to flash that file.)

I got NC stock ROM to see my SD card partition by following item A10. That is most excellent and thanks again!
Unfortunately, I no longer see the boot partition when I attach NC to my computer whether NC is running off stock ROM or CM7. My guess is that this is due to my failed attempt to flash from my CM7 SD card yesterday. Am I right?
I thought I could reverse that by copying the update-stockemmc-vold-fstab-return-to-stock.zip file to CM7's boot (and then booting to the recovery mode) but that seemed to have nothing.
If I understand your previous message correctly, I should re-do my entire SD card but... I have already spent a few hours downloading and customizing the Android apps. Is there a way to preserve all that before Win32diskimager destroys the contents of the SD card?
Is there a way to manually mount the /etc folder from a unix prompt and alter the file?
Does it even matter if I don't see boot while I attach NC to a computer? Are there any caveats to 'let it be'?
Questions, questions and more questions...
That leads me to the obvious question, is there a book that explains Android to someone who is not interested in programming it but wants to understand the architecture and design of the OS (and custom ROMs)?
Thanks for being patient with all these n00b questions.

You do not need or want to re-set up the whole SD installation. Just put the same CM7 zip file back in the boot partition and boot to SD recovery. It will put the correct vold.fstab back on the SD. You will not lose any settings or apps you have already set up. (And putting the return to stock zip there was also the wrong thing to do. The vold.fstab for stock and CM7 are different. But don't worry, it will fix that too.)
You are not supposed to see the boot partition on the PC when you plug the nook in with the cable. You are only supposed to see 'emmc' and 'sdcard'. Under the original setup, your stock system thought the boot partition was 'sdcard' and that was why you saw it on your PC. Since you modified stock to see partition 4 as 'sdcard', partition 4 is what the PC sees, not the boot partition.
Most people have to physically take the card out of the nook and put it in the PC to see the boot partition on the PC. If you don't want to do that, use my script in item B4. But since you are on CM7, you will not be adding many things to the boot partition to install with SD recovery in the future. So it is probably best to leave things be.
And I don't know of any books to help you.

That is excellent news!
A bit of playing around with Astro tells me that I was wrong about seeing the 'CM7 SDCARD' partition when I was on CM7 ROM. I am only seeing the boot. Anyway, I am going to flash the CM7 ROM again and I am hoping it would fix everything.
Also, yes, I can see the boot partition when I put the SD card directly on my computer but I was also able to see it when I hooked up the NC to my computer via USB before I did my unintended tweaks but... I'll survive.
I'll be back after I flash. (Famous last words??)

Mission accomplished!
Thanks again for all your help.

For future reference after you alter stock's fstab... all you have to do is:
mkdir /sdcard/boot (only have to do this one time)
mount /dev/block/mmcblk1p1 /sdcard/boot (do this every time you want to put something on the boot partition)
put anything you want on boot partition in /sdcard/boot

Yes, there is one big advantage to using that method. I think it allows the boot partition to be seen not only on the nook, but also on the PC when you plug in the usb.

We could probably come up with a symlink to /dev/block/mmcblk1p1 to /sdcard/boot and avoid having to mount it everytime as well.

Thank you Dizz, your suggestion got me to thinking and I was able to come up with an init.d bash script that does the trick. I just temporarily mounted sdcard and created the sdcard/boot directory and the mounted the boot partition to it, then unmounted sdcard so it could be mounted again by the system later in the boot sequence.
The only problem is now sdcard will not mount on the PC using UMS mass storage. Must be because of having a second mount within the mount. But it does mount with MTP. But that may be acceptable. I will test some more, including using Goo Manager tomorrow.
EDIT (6-21): Goo Manager works. But I think I have figured out why sdcard is not mounting in UMS. Once it is mounted in my script and the boot partition mounted under it, it cannot be unmounted. And since it cannot be unmounted, it cannot be mounted later by the system as vold. If it cannot be mounted as vold, it does not show in UMS. For now I think I will leave it as I have it in Rev 2 of my script (symlinking to the root directory with full r/w permissions). If people want to see the boot partition on the PC, just use my modified for CM9 NookColorUMS available in my tips thread.

Help!
When CM7 is running, my computer is no longer mounting any of the partitions when I connect NC to my computer via the USB cable.
If the NC stock ROM is running, my computer mounts all three partitions (MyNook..., boot and CM7SDcard) but calibre is not recognizing the external partitions for transfers.
Further, when I boot to my NC stock ROM, I am no longer seeing my SD card's contents in the NC's library.
This may have something to do with the fact that NC stock ROM seemed to have updated itself to 4.1.3.
Should I re-run the scripts again or am I missing something else?

When it was updated to 1.4.3, you lost the emmc mods. Just re-flash my zip with the CWM SD. You may have lost CWM on emmc too.
On CM7, you have to select the turn on storage button after you plug it in. It is not automatic like stock. Pull up the notification area and touch the turn on button.

Darn, I forgot about that 'USB' option under notifications. Enabling it allows me to find the partitions. I will run your scripts again when I find a spare mUSB card.
Thanks again for your help!

Can't write to internal EMMC

Hi,
I have a nook that I rooted and put a custom rom on back about a year and a half ago. I flashed the ROM to the internal EMMC and CWM 3.2.0.1 was flashed as recovery. If it makes any difference it was a CM9 ROM
Now here's where I'm at. I can run ROMs off the sd-card but they are not stable at all. I get a whole bunch of force closes and such.
When I try and flash a new ROM to the internal EMMC it says it completes, but nothing changes. It is still the previous ROM. When I try and format the /data and /system partitions with the EMMC recovery, it doesn't complete. It says there is an error. When I format with TWRP off an sd card, it says it completes but once again, the rom is not wiped.
I've tried the 8 reboot error method, and it never gets to the stock recovery screen. It keeps booting to the EMMC ROM.
I've tried repartioning the EMMC with leapinlar's zip files. It says it successfully completes, but once again nothing changes.
Ideally I'd like to get the emmc back to stock and try and run a rom off the sdcard.
I've read the threads that I thought were applicable to my issues, but nothing seemed to work. I'm completely out of ideas. Anyone have similar issues or can provide some guidance?
Thanks.

The problem you are having running a ROM from SD is the brand and speed of SD you are using. It needs to be SanDisk class 4.
The reason the 8 failed boot does not work is you replaced the stock recovery with CWM. It needs the stock recovery to be able to complete. See my NC tips thread linked in my signature and read item A12. Assuming you can get it to flash, I have a stock recovery zip there.
I don't understand why the ROMs are not flashing. You say it gives errors when you try to wipe with CWM. What do the errors say? You used the internal CWM and TWRP on SD, but none worked. Try my bootable CWM SD to see if that helps.
I don't understand why my partition zips did not work. I know the newest TWRP will not flash them without giving an error 2 message. Try my bootable CWM SD.

Thanks for the advice...
I've been using a Patriot class 10 micro sd to run the roms/attempt to flash new roms. Its worked fine before, but I'll try and pickup another one from someplace.
When I try and format /system and /data from the emmc CWM it says "Error formatting /system" or "error formatting /data" after working away for about 5 minutes
Here's what i did:
Created CWM 6.0.1.2 Bootable SD
- Flashed NookColor-emmc-stockrecovery.zip
- Message said successfull.
- tried to restart and old CWM recovery 3.2.0.1 was still installed
Booted into CWM 6.0.1.2 Bootable SD Recovery
- mounted /system and /data
- attempted to format
- Message "Done." for both
- attempted to flash stock 1.4.3 that you have modified for CWM
- install from sdcard complete
- reboot
- Old CynanogenMod bootscreen and old rom still installed.
Using same CWM 6.0.1.2 Bootable Sd Recovery
-flashed NookColor-emmc-repair-partitions-1-4-5-6-7-8.zip and NookColor-emmc-format-partitions-5-6-7.zip
-said success
-attempted to flash stock 1.4.3
- nothing changed. Old rom still installed
One more thing I noticed:
Everytime I login to the currently flashed rom, any changes I make are never saved. For example, if i install an apk or uninstall an app, the next time i can successfully boot into the emmc ROM, those changes are reversed to the previous version. Could it be that the current rom is being stored somewhere and being reflashed when it tries to bootup?

I hate to say this, but it sounds like your internal embedded card has become read only. I have had this happen to SDs but not to emmc. The apps act like they are writing and if you leave the folder and come back, they are not there. It is like they are writing to a ramdisk instead of your SD. You might try booting to a ROM on SD and see if you can write to any of the internal partitions like /cache or /rom and see if they stick. If not, you may only be able to run off SD and maybe not even then. You might have to change your dalvik cache setting on SD so it uses /data instead of /cache.

I tried copying a file to the emmc partition from twrp and it didn't persist after reboot... so it looks like the emmc is set to read only. I don't supposed I can change that using adb and/or software solutions right? It's a hardware issue?
Any guidance on how to change davlik cache to use /data instead of /cache? I'll be happy to get any sort of stable rom running off any SD card.
I was hoping to repurpose the nook as in in car tablet to tether a data connection to my phone and play music and such.
Thanks for your help. I appreciate you taking the time.

I don't know of anything that can revive it. I never could revive my SD that that happened to.
To make your ROM on SD use /data for all of the dalvik cache, create a file in /data named local.prop. In that file put this line:
dalvik.vm.dexopt-data-only=1
Next time it boots the system file portion of dalvik cache will be on /data along with the installed app portion.
Sent from my stock Nook HD+ using XDA Premium

I now have a stable version of CM 7.2 running off the SD card. I put the davlik cache on the data partition and everything seems to be running pretty smooth.
I'll keep messing around seeing if there is anything to revive the internal emmc, but at least I can use the nook off the SD card again.
Thanks for helping me troubleshoot and figure this out. Cheers.

[Q] xcover 2 bootloop after dba install location change

I'm running deodexed build from this post: http://forum.xda-developers.com/showpost.php?p=40232503&postcount=43 and CWM bootloader. I'm using link2sd and 16GB external CD card.
Strange things started to happen (I think) after using my phone in the swimming pool. Apps from my external card vanished and I couldn't fix this issue, so finally formatted SD card (minitool didn't work, partition toolkit did). Meanwhile every now and then "no place on disk" error while installing apps popped up. Approx. 400 MB of internal storage was free...
After format things started to look promising, but "no place on disk" error still bugged me, so I thougth about workaround, and tried adb shell pm set-install-location 2. After restart I got bootloop. Tried several options and finally was able to flash firmware with odin 1.85. While I was at it, I flashed bootloader with CWM mod and odin 3.09. (Before flashing I was getting an error after restart and had to reboot manually:
E: failed to verify whole-file signature
E: signature verification failed
Click to expand...
Click to collapse
). Well, that worked, and no data was lost, but my external card is unusable, link2sd warns me about my second partition not being automounted and every time I restart phone I'm in the bootloop again, having to flash firmware to be able to unbrick it.
I tried to fix second partition from within partition toolkit, but no luck, formated it, again, but now link2sd doesn't see it mounted at all (partition toolkit does). I've reverted install location already, set it to 0, and later to 1, but no luck... I mean it works, but doesn't solve the problems.
I'm running out of ideas. I backed up everything with titanium backup and I'm considering factory reset, but not sure if it will help at all...

UPDATE:
I bought 32 GB SD card and replaced the old one. Formatted it and things seemed to work, but in roughly 50% of cases I couldn't install application due to "usufficient space on disk" error.
And another issue: yesterday my phone hung, so I restarted it. Basically it entered bootloop, but starts normally as soon as SD card is removed. Recovery log says "can't partition non mmcblk device" regarding SD card.
It looks as if SD card was mountable only when fresh formatted, any application moved to it (link2sd) and things end up as described.
Tried to boot without SD card and insert it later when system starts, but no luck (card is not discovered at all).
I'm seriously considering selling this phone - without external space for installing apps it's next to unusable, and it seems I am not able to solve the issues with SD card.
