CWM on eMMC or SD? - Nook Color General

So I've been on the Android rooting scene for almost two years now (Original Droid owner), but just recently acquired a Nook. I am running CM7 from eMMC, and want to flash clockwork to make updating nightlies easier. I have been running Clockwork from an SD card. Are there any downsides to running Clockwork from eMMC? Can't I always just remove clockwork and have the stock recovery on there?

I never ran CWM from SD, but I find it very convenient having it on eMMC, particularly as I do shuffle my ROMs and partitions periodically just for experimentation's sake.
What you lose is the ability to use eight failed boots to trigger stock recovery. There are situations where that would come in handy--such as hardware faults in the SD slot or screen that make it difficult to use CWM to flash a stock zip, assuming you have a warranty and want to make a claim on those hardware faults.

Thanks for the info, I just got this and its refurbished, so I think I may give it a few weeks before making the transition just in case there are any hardware issues.

[Q] Bricking a Nook Color

Is it possible to "brick" a nook color? I just got mine yesterday, rooted, and decided I didn't like the stock ROM so used CWM to install nookie-froyo. Had some issues with that, and was able to revert back with CWM.
I'd like to tinker more, but I'm a total noob with Android and I don't want to be doing anything that is irreversible. Does installing through CWM do anything that I couldn't fix if I screwed up?
I just want to make sure I don't ruin my new toy only a day after getting it. I'm ready to try froyo again and look into using an OC'd kernel.
With the NC having boot priority on the SD slot the chances of any kind of software induced brick is very very low. You always run the risk of something crazy happening , but it's not a worry I personally have.

Agreed. Short of trying to mess up the boot order or disintegrating the sdcard... it would be tough for a real brick.
Ah, so in other words, if I screw up the on board flash, I can always throw an img on my SD card slot, and do the same process as autonooter?
Good to know, thanks.

More or less that's correct. As far as I see, something physical would have to be damaged in order for you to fully brick. With that in mind, it's not out of the realm of possibility for a severely over aggressive overclock or something of that nature to cause physical damage over time, but all of the OC kernels available here seem well below the level required to fry anything.

There shouldn't be issues with the OC kernel but you do always run the risk of burning out your processor, which is basically bricking your device if you take bricking to mean turning into a brick.

Thanks to the Nook Colors characteristic of booting from the SDcard before the internal, it is very near impossible to brick your nook. Your always able to boot into a Clockwork Mod Recovery sd card even at the worst of times, and from there you can flash a backup, custom ROM, etc.
I take bricking as "Something where it won't boot and isn't recoverable." I know that an OC can do physical harm, I just was wondering that if I flashed a ROM and it went horribly wrong, is it able to be recovered or not. It seems that, yes, it very well is. Which means that I am much more comfortable with trying different roms and kernels, etc.
Thanks again, everyone.

Clockwork mod 3 ok?

ROM Manager says there's an update to Clockwork Mod. 3.0.0.x, is it safe to apply? Running CM7 rc2 right now.
Sent from my Nexus One using XDA App
Why wouldn't it be? And yes it's ok I've been using it since release with no problems.
Yeah it is safe to apply. I've been using it for quite a while.
I've tried to run with clockwork 3.x twice now, and both times my SD card (ext partition) got screwed up to the point that it couldn't mount. The only way I could recover was to reformat the entire card.
I don't know if it was clockwork 3.x, or user error, or just coincidence, but I've never had this problem at other times...
The web is full of similar examples, so until I know for sure, I refuse to use 3.x (I'm a clockwork fan, and use 2.5.1.4).
Sent from my Nexus One using XDA Premium App
Ive had some annoying issues with version 3 also. Never a problem in 2.x
I use RA when I have issues. 3 seems to integrate the GUI but causes problems while actually in recovery mode... I was wondering if I was the only one. I'm definitely a Clockwork fan.
Clockworkmod 3 has problems with sd card, in particular if you are using DT apps2sd.
In my case, it didn't restore to the sd card properly.
I reverted to clockwork 2.5.1.1 and was able to replay my backup. For now, I am staying with 2.5.
yeah cwm 3 has given me nothing but grief. refuses to flash roms, wiping sd card completely, left me in a sticky situation the other day as i had nothing to read my sd card, and have been stuck in the same situation again right now, switching to RA recovery from now on. nothing but grief.
however, glad to see im not just losing my mind and im not the only one experiencing things like this
general consensus is that it is safe some people though like me had issues with it. It wouldnt restore my backups correctly and would freeze in the process. Bc of this i stuck with version 2.5x
I had the same issue with CWM3 totally screwing up my ext3 partition, to top it all off I couldn't access any of my previous backups and wound up having to totally format the SD card complete, repartition and start from scratch with a backup on my PC that was several months old. VERY ANNOYING! Needless to say i now use AmonRA with ZERO issues and I will be pretty hard pressed to go back after that little fiasco...

I couldn't get CWM 3 to complete a backup...pretty essential, so I went back to 2. May try the update and see if it works.
Long ago I had issues where my backup would freeze. Temp fix was to restore each individual section which allowed me to at least restore that backup.

[Q] CM7 to Stock,

I have a question, I was wondering if this is possible. OK, I have been on CM7 for a while now and now I'm looking into going back to stock now there is a way to run CM7 from an SD card, I would like to go that route from now on if possible. OK, little back ground first. I was on GMPower's Auto-Nooter 3.0 running 1.1 software version with CWR 3.0.0.5. When I made the choose to move to CM7, I made a full nanodroid backup first before I made any changes, I also did a test and did a restore to make sure it worked fine. Then I installed CM 7 with 3.0.1.0 and have been running fine (of course with the known issues that CM7 has). Now with the question, If I boot with my Monster RootPack Clockwork Recovery 3.0.0.5 SD since it's CMR 3.0.05, can I restore my nanodroid backup and it restore fine since it should restore all my emmc partitions? I know I would first wipe the cache and then format the /system and /data partitions then do the restore. With all that being said, or would I have to completely return my Nook back to stock and redo everything? If this has been answer please don't shot me and sorry for the bad grammar (I'm no English manger)...LOL
Thanks,
DG
It's possible - I just did the exact same thing myself. So, it can be accomplished. that being said - it took me a while to get it back. I consider myself fairly well versed in most things android (have a 1st gen droid phone for a while now - been through many custom roms), and on my Nook went from stock to rooted stock to cm7. I got to a point where I just wanted to start over fresh, so looked into getting back to a rooted stock version. From what I have found, a lot of what you will go through depends on how deeply you've delved into cm7 (mainly do you have clockwordmod installed on the internal memory, etc. My situation was running cm7 from internal, but was still using clockwork from an SD.
Long story short - my method went something like this (after many trials and errors):
- used the SD I installed CM7 with since it would boot into clockwork.
- formatted system and data
- applied stock 101 zip I had copied to the SD
- had some issues booting correctly (not sure if you will) but ended up holding power and 'n' for about 10 seconds to get to the factory restore and after that completed, my nook booted as it should into a fresh install
-re-rooted using autonooter.
I had attempted the "interrupt power 8x" trick but got nowhere with it since it was a huge pain in the butt to time it correctly. There are lots of great guides around, you just have to find the correct one for your particular situation and may have to use one to get to point A, then another to get to point B.
Hope my ramblings help - bottom line is yes, it's possible

Absolute best/easiest way to completely back up EVERYTHING stock, then dual boot?

To begin, I have a basic knowledge of Android and how it works. I've rooted, bricked, and unbricked my fair share of Android phones, but the NC is a bit of a different animal to me... Phones are pretty consistent in their methods, the NC kind of caught me off guard.
I've perused quite a bit of threads in both the general and dev forums, and found multiple ways of doing multiple things which got a bit confusing, compounded by the fact that Froyo and Eclair methods vary quite a bit on some subjects.
I have a 1.2.0 "blue dot" NC. Things I know to be true:
Have to use latest CWM SD and replace the boot and ramdisk in order to root with manualnooter.
Have to use the correct 2/4/8GB image for my MicroSD (although the size-agnostic SD image threw me for a bit of a loop, but I'll stick with what I know works).
Here are my goals:
I want a complete backup of stock nook in case I have to start over for some reason. Boot, system, ROM, permissions, everything. What is the easiest and/or most complete way of doing so?
I'd like to dual boot stock and CM7 nightlies off of eMMC and use SD strictly for storage (and use a separate SD for recovery). If that's not possible, I'd like CM7 to be on eMMC and stock to be on SD.
If you've got the time and want to write me up a handheld walkthrough, that would be nice, but I don't expect or really need that. All I'm looking for is links to threads that will give me the information I need to figure out for myself what the best way of doing this is. There are a lot of threads for older versions of things, and some of the discrepancies between here and Nookdevs have confused me at times.
Thanks in advance for any help you can offer.
There is a thread HERE , less than 5 posts under this one that explains exactly what you want done.

I saw that thread and deduced that it was probably the best one. My only question left is, how do I make a complete 100 percent backup of stock in case I bugger something up and need to start over?

After you flash clockwork recovery, you can use it to make a nandroid (1:1) backup of your stock setup.
To get a backup: boot into CWM (whether from an sdcard or from emmc) and make a backup - just make sure you have a big enough card.
Then start flashing the zips!
That was my #1 question, I suppose. Nandroid works the same on NC as it does all other devices? I had just read conflicting reports about people fooling with the /system and /data and having trouble restoring from there even after the 8-boot "trick".
Yup, it does. I have needed to flash to stock and to make a bootable nook sd card.
Thanks for all the help, guys! Time to dig into this thing!

[Q] Nook Root

Hello,
I have read and watched and searched different ways on rooting the nook and they all either don't seem to work or are confusing. Can someone point me in the direction of complete step by step instructions for rooting my nook on a micro SD card. I feel dumb while trying to do this because its my first ever root even though I have assembled computers. Its the software that makes me nervous. Thanks for any advice.
I totally understand how you might be hesitant to jump in. I came here a few months ago from a windows phone and had no clue about Android devices. Get yourself a Sandisk card (4 or 8gb ought to do the trick). I went with a cheaper card at first and was very disappointed with the way it worked.
Follow the directions here:
http://forum.xda-developers.com/showthread.php?t=1000957
and you should be fine. good luck!
It may be a little daunting at first (I'm a new NC owner myself). But just keep in mind, the NC is setup to boot off the SD Card first. So you essentially always have a recovery method there. Also, if you don't flash CWM (Clockwork Mod) to be your recovery, you can always use some methods to restore the device ( 8 failed boots for example). The methods are listed on the forums quite a few times. But, basically... android is just another flavor of *nix. Though it does have its own intricacies.
As long as you backup your current setup through CWM's backup operation (AKA: nandroid). You can do pretty much anything and just do a restore to get back to where you started. It's almost like ghosting a computer... It just doesn't redo your partitions.
Get yourself a copy of CWM Here's the most recent 1gb image. This basically gives you a bootable SD Card that can backup/restore the internal memory, format it, and flash images.
You can get the latest cyanogemod rom's nightlies here. You also need Google Apps if you're going to flash the new rom though.
And here's a guide to revert to stock.
Personally, I wouldn't bother with the SD Card system... I would just root the internal rom and flash back if you don't like it.... or flash a different rom, like CM7, if you want the nook to be more of a tablet than an e-reader... just keep in mind... it wasn't meant to be a tablet...
Hopefully this helped.
Ya just wanted to chime in. Its pretty hard to mess up on the process of rooting and if you do there's ton of threads to help you out along the way! Even the NC wasn't meant to be a true android tablet it does the job well and well worth the money. Maybe ill go better later down the road, but after what I paid for this NC brand new on CL I SOOOOO happy!
