[Nook HD WIP] Dual boot stock and CM10.1 Hybrid 6/13

*** The sdcard card created by this thread is not compatible with the original sdcard installation of CM10/CM10.1.
This is a work-in-progress and things are changing very fast so you may lose some of your data as we moved from one version to another.
After a brief discussion with leapinlar few weeks back, this is a new CM10.1 sdcard installation based on that discussion.
Features:
Dual boot stock and CM10.1.
Using only three partitions to allow stock to boot properly.
/data is stored in emmc while /system is in sdcard (Caveat: Doing stock factory reset inside stock will wipe out data of both the stock and CM10.1)
Can be flashed with ROM from this thread starting cm-10.1-20130130-UNOFFICIAL-hummingbird.
/data maximum size is now only limited by the size of the emmc.
For installation instructions follow this post. Thanks Diogenes5.
CWM Image file: sdcard-cwm-hummingbird-hybridv2.zip. Date Posted: 2/2
Data Wipe/Factory Reset now working.
Backup/Restore to/from both emmc and sdcard now also working. (/boot will not be backup and restored)
uImage.20130613.hybrid.hd.zip and update.20130613.ramdisk.hybrid.hd.zip *** latest ***
Fixed: Intermittent boot problem
cyanoboot now working for lg display.
update-20130221.zip
cyanoboot modified to pass serial number to kernel command line for android to properly report a valid number instead of unknown.
update-20130204v2.zip
Fixed device booting to stock recovery instead from the stock ROM.
update-20130204.zip
cyanoboot modified to allow CM10.1 (cm-10.1-20130203-hummingbirdv2 and above) rebooting directly to its menu.
Older downloads:
CWM Image file: sdcard-cwm-hummingbird-hybrid.zip.
Update: Download View attachment update-20130201.zip and extract uImage and ramdisk.stock to the boot partition of the SD card created from the above file. You can now delete kernel.stock as it is no longer being used.
Stock now booting normally.
Added Boot from SD alternate in cyanoboot menu.
Thanks to leapinlar for the suggestions above.
TODO: Wipe/Backup/Restore operations under CWM.
Only CM10.1 ROM dated 1/30/13 and above will work properly with this new SD card installation.
Currently this installation is compatible only with leapinlar Stock recovery tool provided in this thread.

This hack/trick is already superceded by the above post.
BEWARE: This hack/trick should be used only by HD owners who are very familiar with SD card installation of CM10/CM10.1. This may or may not work. Using this tools could brick your device, you have been warned!!!
Prerequisite: Working CM10/CM10.1 SD card installation from this thread.
Instructions
Download the attached hybrid.zip file.
Make a backup copy of /boot/uImage before copying all the files to the /boot partition of the SD card.
Insert SD card to the HD and let the device boot from it.
Hold the 'n' button of the device until the cyanoboot menu is shown.
Press the 'n' button multiple times until 'Initialize Hybrid' is highlighted.
Hold the 'n' button for at least 3 seconds to activate it.
Wait until the device rebooted (Depending on the speed of the SD card, you may have to wait for a long time).
Enjoy a faster and smoother CM10/CM10.1
Note: To uninstall, delete ramdisk.hybrid*, ramdisk.sync*, ramdisk.sys*, ramdisk.data* and u-boot.altboot from the SD card. Delete both cm_system.img and cm_data.img from the EMMC to recover the 2GB of storage space. ​
Technicals/Details
uImage - updated cyanoboot for hybrid booting.
Boot menu descriptions
Boot Hybrid - uses ramdisk.hybrid as the ramdisk.
Initialize Hybrid - uses ramdisk.sync as the ramdisk.
Sync System: SD -> EMMC - uses ramdisk.sys-sync as the ramdisk.
Sync Data: SD -> EMMC - uses ramdisk.data-sync-emmc as the ramdisk.
Sync Data: EMMC -> SD - uses ramdisk.data-sync-sd as the ramdisk.
Default Boot Image - uses u-boot.altboot as configuration file.
ramdisk.sync - will check whether cm_system.img and cm_data.img are present in /emmc. If not create the two files with sizes 800MB and 1200MB respectively. Loop mount both files and copy the contents of partition 2 and partition 3 of the SD card. Rename ramdisk.hybrid.copy to ramdisk.hybrid to enable the cyanoboot menu Boot Hybrid. Store the value 1 to the file u-boot.altboot to enable default booting from hybrid/EMMC.
ramdisk.hybrid.copy - will be renamed automatically by ramdisk.sync to ramdisk.hybrid to enable booting from cyanoboot menu and default booting when the value 1 is stored in u-boot.altboot
ramdisk.sys-sync.copy - should be manually renamed to ramdisk.sys-sync to enable cynoboot menu Sync System: SD -> EMMC. This is needed to update cm_system.img after a CM10/CM10.1 update of the SD card by CWM.
ramdisk.data-sync-emmc.copy and ramdisk.data-sync-sd.copy - should be manually renamed to ramdisk.data-sync-emmc and ramdisk.data-sync-sd to enable syncing data both ways. (Not included yet)
u-boot.altboot - created with a value of 1 by ramdisk.sync. Changing the value to 0 will default to normal SD boot. Value can be changed while in the cyanoboot menu.​
Pros/Cons
Pros
Very fast and smooth interface.
SD card can be unmounted and removed.
Cons
SD card is always needed during boot time.
Update should be done to the SD card first before syncing with EMMC.
Consumed 2GB of spare EMMC storage.
Reboot to recovery sometimes is not working and will reboot to EMMC/Stock recovery.

Bokbokan, if you get this working so that you can get the SD down to 3 or less partitions, I have a trick to let it boot to stock with the card still in.

Is there a speed gain for those whose cards are already faster than nand, or that's mostly for those what have slow(er) cards?

I can try booting from the stock using customized kernel and a ramdisk sourced from the EMMC but so far haven't tested it because of my bricked stock. Did not bother to restore it yet since this make my device easier to boot/reboot from SD.
What trick do you have up your sleeve?

This is very useful for those having very slow/moderate card speed. For faster card the benefit is to allow the device continue running even without the card except during boot time.

Very cool! Will play with this shortly!

Actually there are two ways.
The first is to put the stock ramdisk in the SD boot partition. For me I don't run your CM10 so it was easy for me to make it boot to stock by putting it in the CWM SD card. Then I select SD and it boots to stock. But that does not help CM10 users because they need ramdisk to be for CM10.
But for CM10 users, you can install Quick Boot from the Play Store and install it in CM10. Then tell Quick Boot to boot to bootloader and it boots to stock. But with verygreen's/your CM10 SD partition structure, stock hangs at 99%. That is because stock chokes on 5 partitions on the SD. That is why I was saying that if you could get down to 3 partitions, you could boot to stock from CM10.
But on my HD+, which I do run CM10, I changed the partition structure so it only has 3. But I don't expect users to do that. It needs to be built into the SD from you and verygreen. That is why I like your idea of putting some things on emmc so the partitions can get down to 3.
But I will briefly explain what I did to customize my HD+ CM10 SD. I deleted partition 4 and 5, normally the sdcard partition and the extended partition that holds it. Then I moved partition 2 and 3 to the end of the SD. Then I expanded partition 1 to fill the space. So I have a large fat32 partition 1 and partitions 2 and 3 the same size as original at the end of the SD. Then I modified vold.fstab in /system/etc to point to partition 1 for sdcard instead of 5. And now the hard part. I modified the CWM SD so it also points to partition 1 for sdcard so it can find updates. I also removed the /boot entry so a nandroid would not backup my sdcard as part a backup. The /boot was not backing up/restoring properly anyway.
This is highly customized and I don't think users should do this, but it works.
The down side is your boot files are mixed in with your sdcard files and are vulnerable to tampering by the user. But the Nook Tablet SD installs do this, which is where I got the idea. And on the positive side, Windows can now see sdcard when plugged in directly and stock can use the card as an external SD with no modifications.
One of the challenges for you and verygreen would be how to dynamically build the SD with this structure for varying SD sizes. I had to do it all manually and I don't think you would want users to do have to do that.
So this is just some ideas for future configurations.
Edit: One idea is if you could put /system and /data both on emmc, and create sdcard as p2, then you could have the boot files and sdcard files separate. And it makes it easy to create the SD dynamically. But you do not get the advantage of Windows seeing the partition or stock seeing sdcard without modification.
I do have my HD customized that way. I have my CWM card modified for stock with a big fat32 p2 to use for stock external SD and then modify the stock vold.fstab through symlinking. And I put the stock ramdisk on the SD boot partition like I described earlier. That way I never have to take the SD out. Stock and CWM are available in the boot menu.

Wow! This is great!
[edit - some more thoughts]
Spent some more time playing with this - the performance is vastly, vastly improved over my sdcard. Virtually all lag is gone. The actual conversion process was an absolute snap, and everything is running perfectly. Really, really excellent work.
Now, to upgrade, I assume that I boot into recovery, install the system, then *on next boot* choose the sync to EMMC option? Is that what you suggest?

CyanoBoot is not useable
I have used leapinar's sdcards as well as yours for cm10 and cm10.1 but I have always had this problem where on boot, I can sort of see the screen for cyanoboot, but it is compressed and distorted at the top of tablet. I can not operate the cyanoboot menus at all and pushing n seems to do nothing.
I have copied the hybrid zip files to /boot but the tablet just skips through cyanoboot and boots cm10.1.
How do I get cyanoboot viewable and to function properly?

The way you describe the screen is normal with the flash of distorltion at the top. As soon as you see that flash press and hold the n key until the boot menu comes up. If it does not come up, you may have a defective n key.

I missed adding that in my original question. When the distortion pops up and I press n, the screen goes blank and then nothing ever happens, just a blank screen. I have tried this with 3 different sandisk 4gb class 4 cards and the behavior is the same. My n button seems to work fine under stock, CM, and in CWM; it only seems to be a problem when trying to access cyanoboot.
Do you still think it could be the n button, and if so would there be a way to use ADB to do the hybridization check?
If this is the button how do I get B&N to replace it? "well ya see it works fine until I try to hack your loader and install a third party ROM, can I have a new one?"

You say this happens with my CWM for stock version too? The latest version? Some users were having that problem on an earlier version of my CWM. Bokbokan said earlier that the HD comes with two different screens and my earlier version was failing on one kind of screen. I revised the image and it fixed the problem.

I tried again with different cards using the hummingbird-v3.img from bokokan's HD CM10/10.1 thread. I also used the 6025 for emmc stock rev2 4gb img from your root/gapps thread on a freshly formatted sdcard and I always get the distorted screen.
There is nothing actually being written to the nook correct? Cyanoboot is the u-boot.bin file on the sdcard? Since I have had this problem all along is there a bad file from an early attempt I am not aware of that is on the internal? When I remove any cards the nook boots normally although I used your OTA plus gapps on the stock.

As I said earlier, the jagged distortion at the top of the screen is normal for everyone. And nothing important is being written to internal memory. All files for booting are on the card. I am thinking you may have the second screen manufacturer that bokbokan has not been able to test. Can you run an experiment?
Boot to CM10 and open the terminal emulator app. Type su enter. The prompt should change to a # after you grant superuser access. Then type dmesg. This should be done right after booting so the data is fresh. The screen should scroll a lot of data across the screen. Scroll to the beginning of that data and look for a line that starts "kernel command line:". In that line there should be a statement that says "display.vendor=". Tell us what it says after the equal sign.
I know just enough about this to guess that line is what we want to look at. Bokbokan will have to tell us for sure.

That is the second device he could not test. That is probably the problem. When he catches up with these posts maybe he can do something. His and my device say display.vendor=AUO.

[HDplus - Mostly OBSOLETE] Hybrid SD for CM10/10.1 on the HDplus

UPDATE 5/28/13 - There will be no further development on this thread. Verygreen has changed his SD scheme and they no longer work on this system and Bokbokan has started to develop his own HD+ Hybrid which is better than mine. The Cyanoboot menu works on his and the ROMs come ready for his Hybrid. See his thread here. Some of the other zips on this thread will still work with bokbokan's new HD+ Hybrid.
You can still use this Hybrid on verygreen's Legacy SD ROMs up to 5/29/13 (Legacy only)
Click to expand...
Click to collapse
To see the original Hybrid setup click on the Show Content button.
I have adapted bokbokan's HD Hybrid SD scheme to the HDplus. Hybrid means it has part of the operating system files on the SD and part of them on internal memory. The older Original way of installing to SD put all of the operating system files on the SD. With the Hybrid scheme you can dual boot between CM (Cyanogenmod) on SD and Stock on internal memory. It can boot to stock without stock hanging at 99% like it did with the older Original SD scheme. The CM ROM is put on a specially formatted SD and uses internal memory for storing installed apps and settings. The ROM runs faster and you can run it on some SDs that would not run well under the old scheme. Like the older SD installation, your stock ROM setup is not changed. The CM setup is entirely separate from the stock setup. It uses the same ROMs that are available for the Original SD installation. They are just modified slightly to make them run on the Hybrid. If you decide not to install the Hybrid version and you would like an easy way to install the Original SD, go to my HDplus CM10/10.1 Easy Install Guide and Tools for Original SD here.
If you want to use the Hybrid and you already have an Original SD installation, you must abandon your current SD setup and start with a fresh re-burn of the card. You can use your old CWM (Clockworkmod recovery) on SD to back up your old Original SD installation. Then later, after flashing the ROM on the new SD, you can use your new CWM to do an advanced restore to restore your data. Then your apps and settings will remain.
I do not have the cyanoboot menu working like bokbokan does on the HD, but I have modified the bootloader to be able to manually choose stock or CM when the cyanoboot logo is up. See the section below about booting between ROMs.
Setting up the SD
Begin by downloading the files you need either with stock or your PC. You will need my Hybrid SD image file, attached below, my Hybrid SD CM ROM Converter zip, also attached below, the CM ROM zip you want to install and the gapps zip to match it. Put the last three zips on your internal media sdcard that is built into your Nook. To get them on the internal SD, just download the zips with stock to internal SD or hook your cable to the PC with stock booted and copy to internal SD. You can get the HD+ CM10 ROMs here and the HD+ CM10.1 ROMs here. You can get the gapps zips here, 20121011 for CM10 and 20121212 for CM10.1.
Extract the Hybrid SD image zip and you will have a 117MB .img file. Burn that to your SD with Win32DiskImager in Windows or the dd command in Linux or OSX. The SD can be as small as 2GB. The size does not effect the amount of apps you can install, but the bigger the card, the more media storage space you will have.
To use Win32DiskImager, find it on the web (here, it's free) and install it on your Windows PC. Open it (be sure to run it as administrator) and select the drive (device) that has your card reader with your SD inserted. Then in the image file box put the location where you have the extracted img file. Then when everything is set right, click on the write button. A warning will pop up asking if you want to proceed. When you have verified that you are going to write to the correct device, click on Yes. (One user overwrote their external USB hard drive by not verifying first). If you get an error message about access denied, it means you are looking at the drive with Windows Explorer. Close Windows Explorer and try again. In fact, it is a good idea to close all unnecessary windows when burning, even your browser.
When burning is complete, insert the SD into the Nook and boot. It should boot to the cyanoboot logo and sit there for a little while while it creates the other partitions on the SD. Then it will reboot on its own and take a little more time as it formats the CM10SDCARD partition. Then it will end up in CWM for HD+ Hybrid SD. To use CWM, press the volume up/down keys to move the cursor and the n key to select an item. The power key is the back button.
Installing ROMs
You can use the "install zip from SD/choose zip from internal memory" option to flash the CM ROM you downloaded earlier to your internal memory sdcard. After flashing the ROM and before rebooting, flash my Hybrid SD CM ROM Converter zip. It will make the necessary changes to the ROM to make it work on the Hybrid SD. If you forget to do this, it will hang in the boot animation forever when you reboot. To fix it, you can reboot to CWM to flash the Converter zip. Power off and while rebooting, wait for the small flash and the cyanoboot logo to show, then hold the power and n for a few seconds, let go of power so it does not turn itself off but keep holding n for a few more seconds and then let it go too. It should boot to CWM. Once back in CWM you can flash the converter zip and it should boot ok.
Optionally you can flash the right version of gapps to match your ROM. Gapps can be flashed any time after the ROM is flashed, before or after the converter zip, or even after booting.
When you reboot (you need to leave the SD in the slot), the CM ROM should start. Set it up however you want with your apps and Play Store if you flashed gapps. You can restore your apps with Titanium Backup if you used it. Or you can use the new CWM to do an advanced restore of /data of a prior nandroid backup of your SD installed CM to get your apps and settings back.
If you later want to upgrade your ROM to another build, download it to your CM10SDCARD partition using CM. Then boot to CWM and flash it. Again, immediately flash the converter zip.
UPDATE 5-14-13 - As of 5/5/13 verygreen changed the ramdisk so that the ROM no longer worked on Hybrid. I have now fixed that with rev 3 of the converter zip.
Booting between ROMs
I now have modified the bootloader to be able to boot back to stock. All you have to do is flash the latest version of the Converter zip attached below. It will add the new files necessary to make it work. You can do it even if you have already flashed the rev1 zip. It is not a complete boot menu, but is very simple to operate and it works with verygreen's new kernels. If you want to boot to CM on SD, do nothing and it will boot there automatically. If you want to boot to stock, hold the n key while the cyanoboot logo first comes up and it will boot to stock. And if you hold the n and power key, it will boot to CWM. You can still use the Quick Boot app as discussed in the next paragraph. It still works, there is just the extra step of holding the n key on booting to stock.
To make rebooting between Stock and CM easy, install an app from the Play Store called Quick Boot by Sirius Software. It is free. You can configure the menu choices. I set mine up for Reboot, Bootloader and Power Off. Reboot starts CM, Bootloader starts Stock (but with the new CM10 kernels, you must press the n key when the cyanoboot logo comes up) and of course Power Off turns off the device. I install this on both systems and it allows me to boot back and forth. The app will not run properly on Stock unless it is rooted.
If I want to go to SD recovery (CWM), the Quick Boot recovery option does not work, so I boot to CM and use the power off/reboot menu to select reboot to recovery. If the reboot to recovery option does not display, go to settings, about tablet and tap the build number several times. That will activate development options. Go to that. Then put a check in the Advanced reboot checkbox. Then when you hold the power button and the power off menu pops up, you can select reboot followed by recovery and it will boot to CWM.
Or you could just hold the power + n keys for a few seconds while the cyanoboot first starts. Wait for the cyanoboot logo to show, then press the power and n button together for a few seconds, then release the power button followed by the releasing the n button. It should boot to CWM. If it boots to stock or CM, you did not get the timing right. Try again. If it boots to stock recovery and asks if you want to erase data, click on exit and try again.
I believe the below modifications will still work on Bokokan's HD+ Hybrid. They worked on his HD version so they should work on his HD+ version, but I have not tested them.
Optional Modification to allow Stock to use the Hybrid SD for media storage.
If you want to use the Hybrid sdcard partition to store your media files while running stock, flash one of the four zips I made to help with that. They can be flashed with either the CM Hybrid CWM or my stock CWM. I have them hard coded so they will only effect the settings on stock. One zip, NookHD-HDplus-stock-fix-vold-for-dual-boot-hybrid.zip, will set stock so that it sees the Hybrid SD partition 3 (CM10SDCARD) as ext_sdcard under stock. That way you can access the files that CM puts there and CM can access the files stock puts there. Another zip, NookHD-HDplus-stock-fix-vold-for-dual-boot-hybrid-swapped.zip, will do the same thing but have ext_sdcard and sdcard swapped on stock much like my SDswap zip did. And a third zip, NookHD-HDplus-stock-return-vold-to-stock-settings.zip, will take stock back to the original settings if you want to use an ordinary SD with it. A fourth zip will remove the SDswap feature in stock if you installed it and want to leave the ability to see the Hybrid SD CM10SDCARD partition with stock.
New Stock CWM modified to be compatible with the Hybrid
This setup uses more of your internal data space so if you use older stock CWMs it means larger stock backups as it will backup the SD information along with the stock information. And if you wipe /data with the old CWM it will delete your new SD files. And if you restore an older stock backup with the old CWM, it will overwrite your SD files. I have modified the stock CWM so that when it wipes /data or backs up/restores /data it ignores and does not touch the information stored there for the SD operation. And you can restore old stock backups with the new stock CWM without worry. You can get the new rev3 of HD+ CWM for stock on my HD/HD+ CWM thread.
Swapping emmc and CM10SDCARD
Some users have a small SD card and want their apps to use the large internal media storage to store their data. I have developed a couple of zips to swap the internal and external SDs when booted to CM so your apps can use internal memory, one to add the swap and one to remove it. Get them attached below.
These zips can be flashed with CWM but will only install to the HD/HD+ Hybrid SD with CM. I just added rev2 which fixes a bug. If you already flashed rev0 or rev1, you need to flash the remove zip before you flash the rev2.
With rev2, both SDCARD and EMMC will show internal media storage, as will both MTP folders. A new folder, called ext_sdcard, will show the external Hybrid media partition.
I removed the manual instructions, it got too complicated.
Hybrid on the HD
Big thanks goes to bokbokan for working out the details of this scheme on the HD. All I did was adapt it to the HD+. For those of you with an HD and you have not read about bokbokan's Hybrid for the HD, you can read about it and get his image zip here. But his Hybrid only works on his CM10.1 ROMs. But with his CM10.1, there is no need to convert them. His has them all ready for his Hybrid setup. You can get his ROMs here. You can use my vold zips posted here for modifying stock to see his Hybrid SD, they work on both devices. And you can get rev3 of my stock HD CWM that has been modified to be compatible with his Hybrid SD on my HD/HD+ CWM thread linked in my signature.
Conclusion
I have tested this setup on both CM10 and CM10.1. It definitely runs faster and is more stable. I even have been using it on my PNY 8GB card that I could not even get to work with CM 7.2 on my Nook Color. It runs great now. And I tried the 1/20 version of CM10 that rebooted on me four times the first day I tried that version on my old setup. It has not rebooted once on this setup.
And I just tested it on a 2GB SD. It installs and runs fine. The only difference is it only has a 1GB CM10SDCARD partition.
But it is a work-in-progress so there may be bugs. If you have feedback or questions, reply to this thread. If you are a new user and cannot post here, post on my HD/HD+ tips thread here. Please do not send me private messages or emails. By posting in the forums others get a chance to help you and if I answer your question in the forum, others can see my response and it may help them too. If you post comments on verygreen's ROM threads, be sure to mention you are running his ROM on the Hybrid, including any special modifications you may have made here, like running different kernels.

Thanks Leapinlar! One quick question, before I try it tonight. Does it do anything to your stock install? Of course we shoudl back up...
Also, right now, I have an SD card for stock and an SD card for CM10, seems these will need to be combined somehow? I'm guessing ADB push since you didn't use TWRP?
Thanks

The only thing this does is use more of your internal data space. And of course that means larger stock backups if you do not use my new stock CWM that has been modified to ignore the new SD files there. And if you restore an older stock backup with the old CWM it will overwrite your new SD files.
And I have zips above to make it so stock can use the media partition on the Hybrid SD. To transfer your existing files, just copy the media files from your plain SD to the CM10SDCARD when running the Hybrid CM and using MTP and your PC. And the same for transferring your existing CM10 media files, use MTP.

Re: [HDplus] Hybrid SD for CM10/10.1 on the HDplus and Stock Dual Boot
This is very cool and I hope to get it running tomorrow night. One question. If I copy my titanium backup folder over to stock, can I restore from that? Or does it just need to be the CWM recovery?
I've got a lot installed, so just want to make sure that I get it back instead of having to do it piece at a time.
Also, are apps visible between stock and SD or just data? (In other words, if I install something on CM10, can I access that on stock, or would I have to install the app on both like I do now?)

This is not a new ROM, it is just a new way of installing a ROM. So I doubt there will be any difference in how Bluetooth works.

Er, as in BT doesn't work? At least that's what I notice on CM10. I am unable to pair, though I can see. And other devices can't see the Nook even when 'visible'. PS, I knew BT signal was low, but this seems to be non-existent?

leapinlar said:
You can use the "install zip from SD/install from internal memory" options to flash the CM ROM you downloaded earlier to your internal memory sdcard. Immediately, before rebooting, flash my Hybrid SD CM ROM Converter zip. It will make the necessary changes to the ROM to make it work on the Hybrid SD. If you forget to do this, it will hang in the boot animation forever when you reboot. To fix it, you can reboot to CWM by powering off and holding the power and n key temporarily while rebooting. Not too long with the power key or it will turn itself off. Once back in CWM you can flash the converter zip and it should boot okay.
Then optionally you can flash the right version of gapps to match your ROM.

Just to clarify, Should I install gapps BEFORE installing the converter zip just before rebooting?

It does not matter whether you do the gapps before the converter or after, or not at all. Just do the converter before you reboot.

Migrate sdcard

I've recently flashed vjs ROM below to my old desire.
http://forum.xda-developers.com/showthread.php?p=40191064
I've just got a new 8gb class 6 SD card to upgrade from old smaller class 2.
I think the apps for this ROM are installed to my SD card in some way.
Any tips how I can easily upgrade from old to new SD? I was thinking some kind of sector based copying technique could save me reinstalling ROM and apps? Or am I better to simply plug in new SD card, re flash ROM and reinstall apps?
Thanks in advance

ok that means that your apps are on the sd.
Which recovery do you have right now? and are you s-off?

Yes S off with clockwork recovery v5.0.2.0

Dont think it is significant but thought I'd mention that I did partition the old SD card when I had cyanogen 7 flashed to get more space for apps. I do not know if this partition still exists and if it is in use...I don't think so since I followed instructions for vjs 4.2.2 ROM.
I find partitions with android bit confusing which is frustrating as I've done it with Windows PCs for years

your partition is still there and its in use (all your app are on it). This is what you should do:
1. Install 4ext recovery (much better for the desire than clockwordmod). Go here: http://www.4ext.net/ Download the apk and install it to your phone. Then open the app and donwload/install the new recovery
2. boot into recovery, go to backup | restore, and choose backup
3. after its done reboot your phone
4. Take your old sd out of the phone, and put your new one in. Then follow this guide to partition the new sd: http://forum.xda-developers.com/showthread.php?t=2125513 (use the 4ext method and start at step [4])
5. Once its done reboot the phone.
6. Now put your old sd card into your pc, and copy all of the files onto the pc into a folder.
7. Take out your old sd card, and put the new one in. Then copy all the files over onto the new sd.
8. Put your new sd card into the phone, and boot into recovery.
9. Go to backup|restore and choose restore. Then select the backup.
10. reboot and your done.

Really appreciate your help. Will give that a shot and report back.
Thanks again

i also used that rom for about a month. It was very fast but i kept having random reboots. I ended up switching to the one in my signature. Its not as fast, but in my opinion its more stable, and i'd rather have stability than speed.
4ext is a good recovery because it has a lot of useful features like partitioning the sd (cwm has this too, but its not good), usb unbrick, touchscreen, themeable, one click full wipe, etc... I used to use cwm, and i never had any problems with it, i just recently moved to 4ext and is great.

I have not noticed any reboots as yet, although I will look out for them now lol. Will have a look into that recovery.
Thanks for the advice

OK I partitioned new 8gb SD with 1024mb ext1 no ext2 and no swap. The remaining was fat32. Now I can plug SD card in adapter in windows PC and copy all files from old card to new sd, plug new sd into phone, boot to recovery...but no backup to restore! all the files I copied to the root of SD in windows (inc my nandroid backup) are not visible so I cannot restore my nandroid backup! In recovery all I can see is a folder called 4ext (using apply zip functionality simply to see if I can view files)
Plugging new SD back into windows I can see all the files again!

No.
When I copied files from old SD to windows the PC windows would not recognise the SD directly so I put old sd in phone, booted android then turned on usb storage and copied via usb phone cable.
Windows recognised new SD so I plugged SD card into PC directly (not using phone) to copy files to new card.
I suspect this process may be the problem but do not understand why.

Copied files via USB to phone with new SD card and then restored nandroid...seems to have worked but lags I hoped would be fixed with faster class 6 card still there bit a bit better.

[Nook HD+] CM10.1/SGT7 SD/Hybrid Development (ROM updated 12/31)

CM10.1 ROM with additional SGT7 Framework and Launcher enhancements for Nook HD+.
Similar development for Nook HD can also be downloaded in these threads: Pure SD and Hybrid SD/EMMC.
Features:
cyanoboot menu
Pure SD (4 Partitions)
Install ROM purely in SD card (Speed very dependent on SD card performance)
Dual boot BN Stock and CM (Need to temporarily eject SD while Stock is booting to allow it to boot completely)
Hybrid SD/EMMC (3 Partitions)
ROM System stored in SD card while Data is shared with Stock in EMMC (Better performance than pure SD)
Dual boot BN Stock and CM seamlessly
Installation Instructions:
Download the latest CM10.1 ROM below to your internal storage using the stock BN ROM.
While at it, you may also want to download the latest gapps-jb-20130301 here.
Depending on the type of installation decided, download one of the zip files below to your PC.
Pure SD - sdcard-cwm-ovation-sdv1.img.zip
Hybrid SD/EMMC - sdcard-cwm-ovation-hybridv3.zip *** updated 6/12 ***
For existing hybrid installation, extract file from update.20130612.ramdisk-hybrid.hd+.zip and overwrite ramdisk.hybrid of the boot partition using your PC. Boot and your hybrid setup will now be running under the latest version.
(This will format data in the EMMC stored by leapinlar's HD+ hybrid installation. Use Pure SD installation instead if preserving previous hybrid installation is so desired) Edited: Look here for instruction from leapinlar in preserving previous data.
Extract the downloaded file in step 2 and write the resulting image into the SD card using any appropriate tool. (All data in the card will be destroyed)
Turn the Nook HD+ off and insert the newly written card into its SD slot.
When the device is turned on again, it should be able to boot from the SD card now. (For some SD cards not booting, look here)
The cyanoboot screen will appear at the initial boot. (Do not interrupt during this process. The device will reboot once if installing the Hybrid)
Wait until the CWM Recovery is displayed. (At this point in time, the SD card will be properly partitioned and formatted, ready for ROM flashing)
Install the downloaded ROM in by selecting install zip from sdcard -> choose zip from internal sdcard -> file downloaded in step 1. Do the same with gapps (optional).
Reboot the device and CM10.1 should start booting.
Wait until the ROM is properly booted the first time. (It may take a while and blank/distorted screens may be encountered during this time)
Enjoy your new CM10.1/SGT7.
Update Instructions:
Download the latest CM10.1 ROM below to your internal storage using the stock BN ROM/CM10.1.
Boot into CWM Recovery.
Install the downloaded ROM by selecting install zip from sdcard -> choose zip from internal sdcard -> file downloaded in step 1. No need to reinstall gapps.
Reboot.

First!

Since bokbokan's new HD+ hybrid setup formats my Hybrid data on internal memory, you may want to boot to my Hybrid CWM first and make a backup to internal storage. Then after you use bokbokan's SD to setup and install the ROM and gapps, you should be able to use his CWM to do an advanced restore of data only from internal storage then you will have your apps back. And you probably do want to update to his image because he has made the cyanoboot menu work. And with his zips there is no reason to run my converter zip.
Thanks bokbokan.

This is bokbokan's own development, independent of what verygreen has decided to do with his new SD scheme.
I am terminating my Hybrid development because verygreen's new scheme is not compatible with my Hybrid and bokbokan's Hybrid is superior to mine. His Cyanoboot menu works and his ROMs come ready for Hybrid with no need for conversion.

CM10.1 ROM with additional SGT7 Framework and Launcher enhancements for Nook HD+.
Similar development for Nook HD can also be downloaded in these threads. Pure SD and Hybrid SD/EMMC.
Features:
cyanoboot menu
Pure SD (4 Partitions)
Install ROM purely in SD card (Speed very dependent on SD card performance)
Dual boot BN Stock and CM (Need to temporarily eject SD while Stock is booting to allow it to boot properly)
Hybrid SD/EMMC (3 Partitions)
ROM System stored in SD card while Data is shared with Stock in EMMC (Better performance than pure SD)
Dual boot BN Stock and CM seamlessly

Thank you leapinlar!
bokbokan, I'm excited to try out your setup. Question, if I use the hybrid method (in order to achieve a more stable device on my c10 64gb sd card), how will the different storages be handled? If I download something or if I set something to "on device" in the google play apps (basically cache it long-term), will it store the information on the external card (64gb) or the emmc? Thanks for your help!

If you are asking whether downloads go to external SD vs internal like some of verygreen's newer ROMs do, I suspect they go to external SD.

awesome.
Very cool guys. Thanks for the hard work.
I used to use LeapinLar's method before. So I assume this mod will enabled root apps and/or external sources apps to install without any added steps?

I assume you are talking about my stock mods? This is a CM10.1 ROM for SD and it comes rooted already. But you have to activate unknown sources yourself by going to settings, security and checking off unknown sources.

yes leapinlar, that was what i was talking about. I will go ahead and make those changes.
thanks!

Any plans to make this available as a EMMC install?

+1 for EmmC

I apologize if this is a dumb question, but I am slightly confused here. How is this different than what LeapinLar has been doing?

Just kidding, I think I am understanding it better. Can we still use Leapinlars CWM to flash this ROM?

No you can't use mine. Mine is for stock. This is for SD. And if you mean my hybrid, you should start over with his. See my earlier post on that subject.

So I went for the Hybrid version and here is my initial report:
The device did not at first boot to the SD card. I had to restart the device a few times while holding different variations of buttons to get it to boot from sd. Once I got into CWM, everything went very smooth. The ROM itself was working really well and I was setting it up and everything was running smooth. Google Play Books kept crashing on me so I decided to do a reboot to see if that would help. The device again would not boot into CM (but rather booted into stock) without various reboots by me, so that's frustrating. But even worse, when it finally did start to boot from SD, I keep getting stuck at the cyanboot loading page where it says on the bottom that it's loading hybrid from SD. It never progresses passed that stage....so I can't access the ROM....so I'm stuck. Any advice???

The problem of most SD cards not booting when you initially turn on the device is that they are not "properly" detected right away that is why it will not boot from SD (that is they can not be cold booted). Though they are having problems cold booting, they can easily be booted by a simple OS reboot (warm booting). Shutting down the stock and turning it on is already "cold booting" so it will always boot into stock. You need to root your stock and install app like "Quick Boot (reboot)". Everytime it booted into stock, simply use the app to reboot and normally it should now boot from SD.
Sometimes my version of CM10.1 would not boot because of the graphic subsystem not initializing right away, a simple reboot should do it.

OP updated 20130529

[Nook HD/HD+] Stock 2.2.0 bootable from sdcard updated 01/09

Well, this one was not really asked for, but I need it for my other testing, and I imagine people might be interested in having the option.
This is also a bit more like a proof of concept (and a bit crude at that), even though fully functional - Stock ROM fully bootable from sdcard.
I don't think a lot of people would use this as a daily driver, but it certainly beats having stock on sdcard vs needing to restore stock in EMMC every time you need to test one little thing (or you might buy a few more Nooks, I guess. B&N would certainly appreciate that ).
Limitations and differences from real stock:
- currently there's no access to emmc storage partition as I wanted the setup to remain as vanilla as needed at first
- adb is on by default, though (As root).
- You can actually change files in /system as much as you want - secure mode is off.
For ovation (Nook HD+) You'll need a special ovation image that you'll need to write to an sdcard, at least 4G in size. (gunzip and use dd or winImage)
For hummingbird (Nook HD) You'll need a special hummingbird CWM image that you'll need to write to an sdcard, at least 4G in size. (gunzip and use dd or winImage)
Also get the the stock image (see below) and either place it to internal storage or reboot from the card and use adb push it to /sdcard (basically it's like you install CM ROM, refer to user-friendly thread in General if you cannot follow my condensed instructions here, only use different file name). Note this already has gapps and other stuff, so you don't need any additional installs other than stock at the beginning.
Stock images:
For ovation: stock-ovation-2.2.0.zip (If you are upgrading from 2.1.1 or before, you also need to flash cyanoboot-ovation-2.zip)
For hummingbird: stock-hummingbird-2.2.0-new.zip (If you are upgrading from 2.1.1 or before, you also need to flash cyanoboot-hummingbird-1.zip)
So after you install this thing, reboot. CWM will warn you that the image is not rooted. Decide for yourself if you want to root on the spot or not.
The dimmed Cyanoboot logo will stay on for quite a while (52 seconds for me) - don't worry, it's doing something.
You'll be able to adb in about halfway through that.
Then you'll see familiar Nook Stock white booting screen, this one will stop at 99% - again no fears, it takes quite a while here till the thing rebuilds the caches, on my class4 sandisk it takes 2m40s
Once it's done - you'll be prompted to register and all that.
Now you are done, enjoy.
Now I also have a script to automate creation of the stock zips for sdcard install, so you no longer need o wait for me to create these files
History:
Old Stock images:
For ovation: stock-ovation-2.1.0.zip stock-ovation-2.1.1.zip - these need a special old ovation image
For hummingbird: stock-hummingbird-2.1.1.zip - these need a special old hummingbird CWM image

This is awesome. This way if users want to dual boot, they can put stock on SD, CM10.1 on emmc and not worry about resetting stock. That way they can add things to stock /system directly. Curious to see if the CWM root works.
Thanks for this.

I hope I can just backup existing data partition from emmc stock and restore to sd card stock (via tar or possibly CWM) and the result will run without starting from scratch.

You should be able to, if you backup with the emmc CWM and advance restore just data with SD CWM.

Playstore, "Nandroid Manager" should work nicely, You can specify the location of the CWM backup.

Hello, I am/was planning to install this alongside my CM10.1 EMMC setup, but now that I reread this thread -again- it doesn't seem to have a way to dual boot. I mean when SD would be inserted it would boot to Stock, when not it would boot to CM, but the ideal would to be able to switch from one OS to another w/t having to add/remove the SD card quite as frequently, no?

You can dual boot if you go to my post here:
http://forum.xda-developers.com/showthread.php?p=42295360.
Follow the directions there and it will put the cyanoboot menu on the SD. Then you can change the default to boot to emmc instead of SD if you want. Just remember the terminology is backwards though, stock means emmc and CM10.1 means SD.
Then every time it boots with the SD inserted it will boot to emmc and if you want it to boot fully to SD, just press the n key to get to the menu and choose CM10.1 (SD).

Whoah! That's exactly what I was looking for, didn't know it would work with "Stock-SD" .
Thanks, as always, leap
Now all it remains is to find a way to enable "unknown sources" to this rom and I'll be set (the method used for "emmc-stock" doesn't work here unfortunately).
Again thanks (both to VG and leap, and to the rest of the community that may have helped )

Hello, sorry to double post (and bump this thread) but I found out why's it impossible to enable "unkown sources" using the "extras.zip" that is been given to leaplinlar's thread. Apparently it searches for the EMMC partition whereupon it tries to enable the changes (install zeam, enable "unknown sources", etc). Given that this install uses the SD-card one would only need to redirect "uknown sources" script to search (and run on) SD card.
Given my non-experience in writing android-scripts I found a hard time to do just that, so if leap or anyone else would be able to modify the script (and post it as a flashable zip if possible) so that to run on an external stock setup, I think, it's something that belongs in this thread as it's the only thing missing from VeryGreen's experimental rom (it actually runs perfectly, root included, it only lacks "unknown sources")...
Again thanks, to all involved, for your work.

Just one thing to add (sorry for the double post): This solution does not work as it interferes with VG's method to boot stock from SD. Upon replacing the boot files, it would simply refuse to boot to Stock (SD), it will hang on the selection screen. The EMMC setup -of course- will boot just fine, so I guess that/this need to be reworked as well ... sadly.
Thanks anyhow

any help would be appreciated, i tried installing this the other day to a 4gig sd card, and somehow messed up the 10.1 emmc rom to were it wouldnt boot into it anymore. i thought i did everything right but i guess i didnt.
any words of wisdom? thanks

Did you take the SD out when you tried to boot to CM10.1? If you did and it would still not boot to CM10.1, just reflash the CM10.1 emmc ROM zip again. That should fix CM10.1.

It should not have been a problem. I have not tested it since I don't have his SD set up yet. Did the menu come up? And you choose CM10/CM10.1? And held n for at least 3 seconds?
