If you want stock on internal memory, go to item A15 in the first post.

Then if you want mirage on SD follow the guide in my updated NC SD installation thread also linked in my signature. Just substitute the mirage rom from his thread.

You can put stock on SD. Look at my item B11 in the second post above. Then you can use the cyanoboot menu to boot back and forth without taking the SD out. You might also want to do the media mod in B3 so CM7.2 can use the media partition on the stock SD.

And

I want to install two roms on emmc, I'm done with trying 3-10 times booting and finally booting on SD. Ik there's a guide for multi boot option so I'm guessing there can be 2 roms on emmc? And 2 roms on SD card? But I only want stock + cm7.2 on emmc, so any updated guides?
[Nook Color General] leapinlar:
If you want to dual boot emmc, go to Taosaur's thread on dual booting linked in item B3c in the second post of this thread. It is still valid.

Good evening folks,

I have a nook color I have been trying multiple ways to allow me to load android cm 10.1 to no avail the hardware reset doesn't seem to work also trying to load/boot via SD card and all the many different fashions that are available on the site are not working I can get it to restart and it does come up to where it makes a statement touch the future of reading.

Am no longer able to get beyond the touch the future of reading screen.

Discouraged, and tired. Been trying for the last two days to find a way to get to recovery or just factory reset.

Yesterday was the last flicker of anything like what it's on the site but it referred to a network driver the it's only referenced on Linux not Windows.

I am on Windows 7 64 bit ultimate. Patched current.

I believe my stock Rom ids patched to 1.0.1 release.

This was running sd card for a very long time. Now no longer allows boot via sd. No matter the image I try, no dice. 3.0, 2.2, 2.1.

Tried to get adb access. No dice. Refuses to connect.

At wits end, looking for ideas.

The unit is physically in good shape.

Gate to retire a unit that looks like it should run for years to come.

Did you replace stock recovery with TWRP or CWM? If you did not, you should be able to do the 8 failed boot procedure as described in my OP.

And by the version numbers for your boot SD, it sounds like you are trying to boot to a TWRP SD. Try a CWM SD from my OP. Also pay attention to my tips in A9 when burning.

Edit: And are you sure you have a Nook Color instead of a Nook Tablet? A Nook Tablet has a silver bezel and the NC bootable SD's will not work on it.
[Nook Color General] Carydc:
thank you for assistance. checking your suggestions now.

I have Nook Color Dark Grey Bezel not light Silver. I will try the A9 suggestion and CWM. I like CWM over TWRP. I believe I did replace stock recovery. Thank you for the tip. Will keep you in the loop. The 8 failed boots is not working.

Am Able to get to the CWM based Recovery v5.5.0.4 now. Thank you. I can rest easy now. The image worked like a charm. Now I can put the CM 10.1 and gapps on this nook color. Will put it on the main system. Will follow your instructions and downloads.

Thank you again. This is almost like a rite of passage.

I was in a huge jam with my Nook Color, and this completely solved the issue. THANK YOU!
[Nook Color General] Great_Bizarro:
For those running c10 and having problems with low volume here is the answer.

Volume+ is available herehttp://androidaudiohacks.com/?page_id=16 Download it and install.

You will need to remove the built in DSP Manager. Easy way is using Titanium Backup or Rom Toolbox Lite to remove it (if you update your rom you will need to remove it again)then install Volume+ go to Settings and select Sound and under Music effects select Volume+, then in Volume+ make your adjustments. I have found on my Nook that only the Speaker Setting has an affect on the speaker and headphones and the Headset Setting does nothing I have found. If there is an easier way let me know.

I have CM 10.1.2 stable installed on SD (16GB Sandisk Class 4) with Stock ROM 1.4.3 on EMMC.

I am trying to follow Tip B3. Speeding up booting by modifying the dalvik cache setting.

I created the text file local.prop (without an extension), but I'm not sure where if I've put it in the proper folder.

In ES File Explorer I did this...

o click "/ Device"

o click sdboot (this icon has a shortcut arrow on it)

o Here I see some file names I recognize as CM files: uAltImg, uAltRAM, etc,

and these Folders: B&N Downloads, Digital Editions, LOST.DIR, My Files

o Since there is no "data" folder here, I create one.

o I copy my local.prop file to the data folder I just created.

Is this correct? It seems like it probably is, but I would like to be sure before I try it as I don't want to mess things up.

Thank you,

Lilla
[Nook Color General] leapinlar:
No that is not quite right.

You want to just to put that file directly in the 'data' folder at the top level directly below '/', not in the sdboot folder. That sdboot folder is pointing to your boot partition on the sd.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook Color General] LILLA45:
OK, I think I've got it now. I deleted the unnecessary folder I created, and put the local.prop the \data folder that comes up when I press "\ Device" in ES File Explorer.

In ES File Explorer I did this...

o click "/ Device"

o click data

o I copy my local.prop text file (without .txt on the end) to the data folder.

I am running CM 10.1.2 Stable on SD (16GB Sandisk class 4) with B&N Stock 1.4.3 on EMMC

I installed AlternateCWM-SDInstalls-Rev2-v6.0.1.2

In an attempt to fix some battery life problems I did the following using Alt CWM for SD...

Use #1

* I wiped dalvik cache

* I did "Reboot Recovery". Why? I had not yet discovered that I could press the power button and return to the previous screen where I could have selected "Reboot system now".

Observation: It rebooted to EMMC/Stock 1.4.3

Use #2

* I made a backup using this the “Backup” option on the Backup and Restore Menu. I didn’t select a backup format.

* I wiped cache partition

* I wiped dalvik cache

* I did "Reboot system now"

Observation: It rebooted to CM

Question: What is the difference between Reboot Recovery and Reboot system now, when should I use each?

Thank you,

Lilla
[Nook Color General] leapinlar:
You should use reboot system now when you finish. If you still have the SD inserted, it boots to the ROM on SD. If you take the SD out before you select it, it boots to stock.

Reboot recovery seems to be broken on SD installs. It should reboot directly back to recovery, but does not. So don't use it.

[Nook Color General] echoedge:
hey leapinlar or anyone else who knows,

with your AltSD and being able to make cwmrecoveries from an SD card boot, how does one recover a backup from the sd card?

Say I made a backup, restart, go into your CWM, and click restore and restore a backup from within the sdcard.

All I get is a boot-loop on the next restart, no restore.

What's the point (other than the other options available in CWM) of being able to make backups of your SD boot if you can't recover the backup? Or am I missing something?

Thanks :)
[Nook Color General] leapinlar:
That should have worked. Was the card you were restoring to one already set up for booting to SD?

[Nook Color General] echoedge:

[Nook Color General] echoedge:
Ok. I'll try it again when I get a chance and let ya know.
[Nook Color General] echoedge:
Right-e-o, sorry for wasting your time. Honestly I tried this months and months ago and assumed there was some trick behind it and didn't bother, in foresight when I tried to do a restore I didn't properly have all the 'blob' files which i was and am a bit unfamiliar with clockworkmod recoveries.

But just tried it, and it worked. Brilliant! :good:

Now I wonder if the backup and restore options on this alternate sd boot are just specific to the backups and blobs, or can I use something like onandroid

http://xdaforums.com/showthread.php?t=1620255

make a backup that way on the sd card and restore in the cwm.

edit:

OK, I think I'm starting to get it.

Go into backup and restore > choose backup format

and you can choose between .dup and .tar file format.

If i'm not mistaken the .dup has the blob folder I was unfamiliar with, changing the default to .tar should clean things up to the way I am used to (even though onandroid has the option of selecting between .dup and .tar backups, the default there is .tar)

Transfering uAltImg and uAltRam to the SD card

I'm a noob, and I've successfully unrared the file, but now have two questions about this.

What exactly is the boot partition; what is its path?

I use an app called Droid NAS that makes the Nook Color show up in the OS X Finder; makes it really easy to keep the SD card in the tablet and wirelessly transfer files from my Mac to the card. But can I use it to transfer uAltImg and uAltRam? Not sure if Droid NAS gives me access to the correct destination directory.

Thanks
[Nook Color General] leapinlar:
You need to take the sdcard out of the nook and insert it into a card reader in your PC. The boot partition is the first partition on the card. You should be able to copy the two files there.

OK, this is what happens when an 'experienced' user is not paying attention... I installed latest nightly Cyanogen ROM to my Nook Color, then very carefully choose a Nook TABLET kernel, and installed over it.

Can no longer mount any internal storage, and am unable to install any zips, obviously, including all the partition recovery ones. I've tried to pull off the '8-reboots-to-stock' trick, does not seem doable with the cyanoboot bootloader I have installed. I can boot off of SD Cards.

Any thoughts appreciated!
[Nook Color General] leapinlar:
The 8 failed boot did not work because you do not have the stock recovery installed.

You need to boot to CWM on SD and flash my repair zip from my partition repair thread. If you are saying you cannot do that, that means your partition table is borked and you must manually rebuild it.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook Color General] friedsonjm:
The partition table is indeed borked. How do I manually rebuild it?
[Nook Color General] leapinlar:
Not easily, but since you say you are an experienced user you might be able to do it.

First thing to do is boot to the CWM SD and get ADB working so you can do some fdisk commands. Let me know when you get that far.

Edit: if you don't know how to do that, try to make a CM7 on SD and I can walk you through how to use terminal emulator to do it from there.

OK, very late here so will try in the morning. I'm familiar with fdisk, so it sounds like their is some hope!

Ok, I am on the west coast so may not be up yet to help you when you need it. Be sure to see my edit above if you have trouble with ADB.

No vold.fstab in CM10.2 (Android 4.3)

I recently installed CM10.2 Nightly (to EMMC) and no longer have the vold.fstab to modify as mentioned in tip B3 (change auto to 4). I have not been able to find a technique to do this which will allow my SDCard partition 4 to be mounted instead of the small partition 1.

The card is used to boot an alternate rom tho I have not done this since switching to EMMC.

Thanks,

Gary Davis
[Nook Color General] leapinlar:
CM10.2 no longer uses vold.fstab. It uses fstab.encore.rc which is part of the ramdisk and cannot be modified so that it sees the p4 without modifying the ramdisk. I had to mess with that on the SD install image so that my image would work on CM10.2 on SD. But it is possible to modify it with startup scripts. Look in my SD thread and see some of my latest posts there. Those were focused on swapping stock SDs, but the same principle applies.

Sent from my Nook HD+ running CM10.1 on emmc.
[Nook Color General] gardavis:
Thanks. I was not able to find the thread posts you mentioned but did eventually solve the issue and got my SDCard partition #4 mounted. Maybe there is an easier way but what I did was...

1. Mount the boot partition to get at uRamdisk

2. Use the BootUtil tool to extract fstab.encore file.

3. Edit the sdcard1 line to change the 2nd "auto" to "4"

4. Use BootUtil to replace the file back into uRamdisk

I did blog the gory details here.

You mention startup scripts. I did notice that /system/etc/init.d/90userinit will invoke a script /data/local/userinit.sh if it exists so perhaps a mount command there would do the trick easier (maybe also a umount might be needed first). This file also would probably survive ROM updates.

Thanks,
[Nook Color General] leapinlar:
Yes, scripts are easier and survive a new ROM flash. Here is the post:

But steven676 recommended the -o commands be changed to:

umask=0702,uid=1000,gid=1015

to make the write permissions safer.

EDIT: I tried these -o commands and my system locked up on boot. Best to leave them be as in the original post

[Nook Color General] DizzyDen:
You could do this to the ramdisk.img file in the ROM zip files prior to flashing instead of having to flash then edit on the device... I'm kicking around the idea of adding this ability to my IMEI Generator program.

bootutil /v /x ramdisk.img fstab.encore

use a unix compatible editor to change the sdcard1 line (could also use a windows/dos based sed included here):

sed -i s/sdcard:auto/sdcard:4/ fstab.encore

bootutil /v /r ramdisk.img fstab.encore

Bootable SD issues

I'm trying to fix a Nook Color that has been installed with CM10.something, but hangs on the cm loading screen and the screen goes black.

EMMC version syas its from Nov 23 2012

I can get to the EMMC bootmenu. In this menu the SD Card options have never shown up.

If I load Internal eMMC Recovery random pixels turn on to the right of the screen before it loads CWN Recovery v5.0.2.8.

Within recovery I can access zips.\

If I try to install a recent cm-10.2-...nightly....zip I get the error...

Installing update...
assert failed: getprop("ro.product.device" == "encore" || getprop("ro.build.product") == "encore"
E:Error in /sdcard/cm-10.....zip
(Status 7)
Installation aborted.

I have attempted to create a bootable sd multiple times. (A 10) The Nook has not booted from a sd

I believe I am following procedure correctly.

Any ideas to work this out would be appreciated. Let me know if I can provide more info :)

Since you got that error, you do not have a Nook Color, you probably have a Nook Tablet. Does it have a silver bezel? If it does it is an NT. The Nook Color files do not work on the Tablet.

Please help...

I am in a dire situation with my NC. I accidentally rooted my NC's OS instead of installing it on an SD card like I wanted too (not extremely tech savvy, and have only rooted once, a couple years ago). I tried to do a regular factory restore (failed reboot 8 times) thinking that would take it back to factory settings and I could start over. But I seemed to have messed up my NC and now it's showing no storage capacity no matter how many times I factory reset it or erase/deregister it. I'm not sure what to do and have searched and searched and don't see anything talking about this type of situation. If you could please help..or anyone, I would greatly appreciate it. I can donate to someone to help too. I also thought I messed up my removable drives too b/c anytime I would format and insert my sd card then try to write to it it would tell me my card needed formatted (although I'd just done it). I tried it on another laptop though and the same thing happened, so that makes me wonder if I messed up the sd card somehow and not the drive?? So, confused.
[Nook Color General] leapinlar:
Sounds like you may have messed up your partitions. I recommend you go to my NC partition repair thread linked in my signature. Flash the repair and format zips. Then go to my NC tips thread and read item A15 for how to get stock back.

As far as formatting your SD, use SDFormatter free on the web.
[Nook Color General] Supergirl9801:
I see your links over there but pardon my ignorance on your instructions. What do you mean by "Flash the repair"..do I just add the file to my sd and pop it in my nook and it will automatically boot up and repair or do I have to "write" it using win32 first or unzip it somehow first.
[Nook Color General] leapinlar:
Neither of those. I mean make a bootable CWM SD per my instructions, boot to it and "install" or flash the zips with CWM.
[Nook Color General] Supergirl9801:
varyHo take

And that's these " Nook Color Installation Instructions for CM7/CM9/CM10/CM10.1/CM10.2 on SD" instructions right?? If so, that's where I'm running into trouble. After I flash the uRecRam-7 file, I try to open it in my computer file to add the other zipped files and it pops up a box telling me I need to format that drive??
[Nook Color General] leapinlar:
No.

Let me start fresh. It is confusing trying to follow two threads.

You need to make a bootable CWM SD from item A10 in this thread. But it is sounding like you are having trouble making one. After you write the image using win32diskimager, you need to eject the SD temporarily and re-insert so that your PC can recognize it. Then you can copy the repair zips from my repair thread and use the new bootable CWM to install them. That should fix your stock partitions.

Then go to item A15 and follow that to get stock back.

Then if you want to put CM10.2 on SD, go to that thread you referenced above and start over with the SD.
[Nook Color General] Supergirl9801:
I've tried ejecting it...still doesn't work and says I need to format..grrrr!!
[Nook Color General] leapinlar:
You totally removed it and re-inserted it?

Try re-formatting it with SDFormatter before again burning with win32diskimager. You can get that program free on the web.

If that does not work, I suspect you have a bad SD.
[Nook Color General] Supergirl9801:
Yes I've used that and am still having the problem. I said screw it, called B&N and complained out the wazoo about the crazy crappy stuff I've been dealing with with this darn thing and they're letting me do an "out of warranty exchange"...I'm getting the hd+ for only $100....can't beat that and I don't have to deal with rooting or trying to partition the darn thing just to get google play and some basic gaming apps.

I feel like kind of a noob for asking this but.. what if I just want to update a rom (just another progression/update from the same rom/build), but not fill it up with all the bloatware again... i guess, just updating the rom but not touching the current data?

I don't know why that feels like a weird question... this is sd boot btw.

thanks :)
[Nook Color General] leapinlar:
Yes you can just update over the existing rom without wiping. But I don't know what you mean by filling up with bloatware again.

But with the SD install, you know the update procedure is different than the emmc install, right?
[Nook Color General] leapinlar:
(Moved from the CM11 thread).

The problem is your restore did not complete properly and now you are missing the files you need on the boot partition for it to turn on.

The solution is to make a bootable CWM SD from my item A10 in the first post of this thread. Then you can flash a CM ROM (not CM11) with that. That will restore everything. Be sure to factory reset with CWM before you remove the SD and reboot.

(You can also use that CWM to flash the 6.0.4.5 CWM to internal memory so you can then boot to it to flash your built CM11).
[Nook Color General] unibroker:
Your instructions and zip did the trick! Just a side note; when I initially booted into TWRP 2.4.1 after recovering with CWM, I tried restoring my backup again and again the same thing happened but I noted the error message of not being able to untar the boot before I rebooted. I made the backup with TWRP 2.3.1 and the restore problems started happening with 2.4.1. Maybe it's a quirk with my download because I assumed they would be backwards compatible. In any event I've re-flashed TWRP 2.3.1 and after my NC charges up I will try the restore. I assume it will go off without a hitch because I've already restored this backup successfully with this version.

Thanks again.
