SD Card changed format, lost all my apps, can't reinstall. Help!

So I just traded my iPhone for a rooted MyTouch. It has the Cyanogen mod I believe. Well all of a sudden I could not access my SD card and when I tried to open it on my computer it said 'Wrong Format'. Wouldn't work on the phone either. So I formated Fat32 and thought I could start over.
It still shows my apps installed in the Marketplace, although they were on the SD and deleted. I can't uninstall them, but it thinks they are there, somewhere. Has anyone had this problem? I am relatively new to Android and rooting. I had a jailbroken iPhone before. Thanks!

kinda depends really. I would suggest first going thru recovery console if you are using amon recovery and partition sd card there. With most modified roms you have apps 2 sd so there are actually 3 partions. The biggest is fat32 for data like music, then ext2,3,4 for applications then a linux swap partition to help expand the ram on the phone and if you formated on PC or from settings on phone those partitions are gone. So I would do that first and then try to uninstall from market and reinstall again if not you may need to wipe and restart the device.

How do I get into recovery mode? I tried going to the terminal and using the flash_image recovery /sdcard/imgfile but it says I do not have permission?
Any ideas??

If your phone has been rooted right by the previous owner, you can access the recovery mode by first powering down, then pressing home and power at the same time.

Ahh! That worked! thanks!

I have a variation on this problem and lost my apps and Market, hope someone can help. Started with the SD card coming unmounted randomly, known issue with EVO I guess. Followed the recommendation of reformatting the SD by plugging it into a Windows PC and doing a FAT32 format. I backed up everything I could "see" from SD to C: drive. I am running a custom ROM with APPS2SD feature and Clockworkmod recovery. I'm very new to Linix and Android but, it looks like there is a Linix Ext3 partition that is made by APPS2SD on the SD card and that is where all my apps where, including android Market app. So, upon copying all the folders back to the re-formatted SD I had no apps and no android Market to able to re-download all my apps. I guess Market is like a licensed deal that you can't just get a .apk of and reload it. I do HAVE a current recovery backup that was on the FAT32 directory of the SD card but it appears the the Ext3 partition is not in that recovery file. I tried booting into recovery with Clockworkmod and reformatting the SD again, I tried a "Restore ext3.img" but Clockworkmod comes back with 'sd-ext.img not found" so I am guessing that the Linix Ext3 partition backup was stored IN the Ext3 partition of the SD(?) and the system and data stuff is stored in the FAT32 recovery file. Brilliant idea (not)! I tried a re-flash of the ROM, flashes OK but no apps. Anyway, the SD is properly partitioned now, the FAT32 stuff is back on, I don't know how to look in to the Est3 partition but, I know there is one program there cause I installed a file explorer by downloading and executing an .apk and there was an option to install it to SD. Going to factory reset and starting over again is not an option. Any ideas please?

SOLVED this issue:
apperantly the android market application is called "vendor.apk" and can be downloaded from various sites BUT WAIT, it's not that simple. Apperantly the vendor app has to be specific to your phone (hardware)? On a whim, I downoaded the previous version of my custom ROM (happedned to be Fresh ROM) .zip, I extracted the vendor.apk from the .zip and installed that. Then, I had an apk called MarketUpdater.apk, or something like that, that had installed in the phones system/app from the last Fresh ROM update. I ran this to update the vendor (android market) to the latest version, then I ran that. Did it work? NO, it crashed hen I tied to run market. I then did a re-boot. Did it it work? NO Upon attempting to reboot it got stuck in a loop and froze. Very scary. So, remove the battery and try again. I think I had to remove and re-install the SDcard somewhere in there to get it to a first time boot and, after a re-boot, whalla, come back with a working market. Market remembered all the apps that I purchased and I re-downloaded everything. Of course, I don't know for sure where they are stored right now (SD card or phone??)
And, my original problem of SD card constantly coming unmounted has been fixed.

[Q] Accessing CM7 SDcard while using standard Nook firmware

Just got my NC last week and thanks to this site have successfully been running CM7 (latest stable version) on a 16GB Sandisk class 4 card. I have put a few movies into a folder on the SDcard in a folder I created /MyFiles/videos. CM7 automatically found them and they playback fine.
For kicks, I booted into the emmc mode last night (running 1.3). I can browse my SDcard and see the /MyFiles/videos folder, but no files show up. Shouldn't I be able to see these files while booting with the standard Nook mode?

What a SD CM7 sees as the "sdcard" is partition 4 on the card... stock does not see this partition... what stock is seeing is the first (or "boot") partition on the card.

Thanks for the reply. That's weird because I don't think I created the path /MyFiles/videos anywhere on the first partition but I was seeing that folder. Looks like my something is messed up though as I can't get my CM7 to even boot now. It just sits there spinning at the CM7 logo. Any ideas?

Another update. I put the SD card in a USB reader and put it in my Linux machine. It sees all 4 partitions and my files are still where I thought they were. The CM7 SDCARD partition has a /MyFiles/Videos with my movies in it and the /boot partition has a /My Files/Videos folder that is empty. So all of that explains why I couldn't see my files when booted into standard Nook mode, but I still can't boot into CM7. Please help.

Why did you created /My Files/Videos folder in the /boot partition?
First step would be delete them off.

I don't even remember doing that, but it is possible that I did. Deleting those files didn't fix it.
I just remembered something else I did. When I was trying to boot into Nook mode, I forgot to hold in the nook key so it started booting into CM7. When it did that I held in the power button to turn it back off. That is probably what horked up my CM7.

Do you have a clean backup? Try that?
Worst case, redo your uSD

Unfortunately, I'm so new to this I haven't even looked into how to back it up. I downloaded the free version of Titanium backup but hadn't messed around with it yet.
I used Evergreen's method for installing with the size agnostic image. Is there a way to reinstall without wiping the uSD card and starting from scratch?

Try just putting the same nightly or stable build you used before on the boot partition and boot into verygreen's recovery mode.

Tried that and it didn't work either. I've given up and just started over from scratch. Will have to look into a backup procedure. Thanks everyone for the suggestions.

Honestly, I didn't even know or remember how to make a copy if running off uSD.
Clone it, maybe?

Using the auto-recovery method on the SD card then the file must be called update-gb-*.zip for it to install it. It is also aware of files called gapps-gb-*.zip. Any other files will be ignored.
Providing the file is named like that then you should see it install it when powered up with N key pressed and recovery selected.

I just meant the recovery mechanism that comes with the SD boot. Powering up with N key on and selecting recovery boots into a mode where it will just install the zips I mentioned and not a full menu driven recovery mode where you can reformat partitions, select which zips to install etc.

He asked how to make a backup, not how to install or update.

[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.

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.

Nook Color with CM7 - Boot-looping

I changed the Android ID on my Nook Color (with Titanium Backup Pro) and now it is boot-looping, at the point where the arrow head moves around in a circle. It is running CM7, but I'm sure the rom is at least a year old. I think it has CWM recovery. How do I get to recovery and what should I do?
[edit] I found this thread and will see if there is something I can use.[/edit]

I pulled the microSDHD from the device and I can read the boot partition on my PC. Before I attempt repair, I want to copy a few data files from the SDCard's data partition, but I do not see it. How do I mount the SDcard partition so that I can copy the files? I know how to do this once I can successfully boot to the Android desktop, but not without the desktop.
I looked through verygreen's SDCard installation instructions here and I can execute boot into recovery, but that just looks for update files and shuts down. I did not get a menu to allow me to mount the data partition via USB for the PC to read or for any options at all.

I have a bootable SDCard (verygreen's) and removed it to boot from emmc. That works, so the problem is on the microSDHC. When I insert the microSDHC (8GB) card in the card reader on my PC, I see the first three partitions are healthy and the last (5.9GB) is not. The only partition that I can assign a drive letter to is the first partition, Boot. Is there any repair I can do to that forth partition?
