[Q] Two Simple questions!

Hey Everyone, first off. I love you all. You've made me LOVE my Vibrant and NookColor more than ever!
I have two questions.. (sry my search on the site wasn't working )
1. I had a 4gb microsd card that I used to put the Autonooter for NC on it. Now I'm seeing alot of updates with froyo and overclocking kernels and I want to try them out. But my 4gb card is frozen solid at 32mb, I tried formating a through windows, I read on another post that I cant find at all that theres a better program out there for fully formatting microsd cards back to the original state.. Does anyone know the program?
2. I've been reading daily on the updates for Froyo, Which one is the current most stable version?
----
Thanks!!!

1. Put the uSD card back into your NC. Under the original (BN) Settings ---> Device Info ---> SD card : first unmount the uSD card, then format it. Then remove from NC.
2. Not my thing, no help, sorry.

Thanks for the help on the SD Card! First step done, alot more to go!

Okay, So I installed Clockwork Recovery and made a backup of my system. After I installed clockwork, My nook froze at boot, I figured out how to get into clockwork recovery and I am currently restoring my eclair.
I see alot of people using froyo, which build and what post did everyone do it from? I see alot of eMMC but I see a Development build.. I'm confused as to which one I should get.
Thanks!

[Q] root/rom question

now I realize I'll prolly get the lynch mob soon after i post this... being that all the research is over in the dev section, but my question is fairly complicated and i cant seem to find a direct answer from my own reading.
now i have root on my NC and i would love to put a custom recovery/rom on my NC. could any one point me in the right direction to get me started loading a custom recovery? i dont want to run froyo off of an SD card i would love to have it just be a giant version of my phone(I'm sorry if that's asking to much)
i learned and pushed myself to do it a while back on my EVO 4g when i saw there was a rom with wimax capability's and that was my first time rooting anything. I do on the other hand work as a sprint instore service and repair tech. so all of this reading isnt completely lost on me.
and my second question. when i booted my nook back up after i let the battery die, all my setting and apps were gone. any one know anything about it?
thank you for any answer, and I'm very sorry about my spelling and grammar, i know it sucks >.<

i think my biggest confusion/hangup so far has been the custom recovery not sure if i have this right or not but. these are the steps (i think) i need to take.
1. aquire root. [check]
2.custom recovery.[?]
3.custom kernel.[?]
4. custom rom.[?]

So what you want to do is flash a custom rom? You would just download a CWM sd card image. Burn that image to your SD card. Then, grab the rom you want, such as nookie-froyo, or whatever. Copy that zip to the SD card.
Put the SD card into your nook, then reboot. It should boot into CWR and from there you can just flash the zip. The same thing with a custom kernel, just copy the zip onto your CWM sd card, reboot, and flash the zip.
I'm not sure if that is what you are asking, though.

I've actually figured it all out finally. is there any way to see what my CPU is running at?

The speed of your NC can be done by downloading 2 free apps in the market:
Linpack for Android
Quadrant Standard
The Linpack app will tell you how many MFLOPS (Millions of Floating Point Operations Per Second) and Quadrant will give you a score to benchmark for CPU, I/O, and graphics. They will also give you as a reference how you compare to other devices.

So I'm new to Nook. In fact it's still being shipped for the wife, lol. Little that she knows, it's getting nootered before it even gets in her hands.
I've rooted phones and flashed custom ROMs.
From what you're saying above, does CWM reside solely on the SD card? That's different than a mobile phone. So any time we need to install a custom ROM (even the first time), we'd have to boot using the SD Card that has CWM, right? Of course I'd have to root the nook first.
following should really go into a different thread:
So whats the best ROM? So many out there. I just want to be able to use all google apps and market (for kindle app).
Thanks in advance.

You can still install Clockwork from the market and it'll run of the NC without an SD card. I've done it. But for the installation of CM7 (something to do with EXT4? I don't even know what that means...) CWM on an SD was necessary.
On what the best ROM is. Well, looking in the general section subsection here it looks like a lot of people are on rooted stock 1.1. I tried Froyo and it was cool and all, but I missed having the full 8GB of storage on the nook. I haven't tried Honeycomb yet, so no idea on that one. I currently have CM7 nightly 8 on my NC and really like it. I may not have all the storage space still (they're working on it) but it's snappy and sleek.

[Q] Nook Color honeycomb

Does anyone know how to test if a bootable sdcard with nookie honeycomb actually works before you test it out on the nook color? thnx
btw i used the process that was on this site http://theunlockr.com/2011/02/07/how-to-load-honeycomb-android-3-0-on-the-nook-color-usd-method/

Not sure why you need to test it before putting it in the nook. If you're worried about doing any harm to the nook it's really not possible. Just put the card in and try to boot. If it doesn't boot take the card out and boot up normally, no harm no foul.

I second this. By default, all the Main Roms for Nookie Froyo and Nookie Honeycomb have no features enabled that will touch your Nook Color. The only thing it touches on the NC is the Cache Partition in order to prevent too many writes to the SD and to also speed things up. Anything done there won't screw up your NC in a Million years and Switching back to Stock and doing a few things will wipe any evidence. Or if really paranoid you can Flash back to Factory to ensure all is wiped.

thnx u guys, But i have another problem. i succesfully installed the honeycomb and got it to work on the nook color. But when I go to my computer with the sd card plugged in, it says that i only have 115 mb of data on the card. I have an 8 gb card. It's not left on the card, it says 115 mb out of 115 mb of data, even after i deleted everything. Anybody know how to restore it back to the 8 gb data amount thnxx

NookColor Format and partition your SD card back to a usable state

Opinion
Since the OP seems to have been answered, I'd like to piggy back a bit
Been doing some reading on the forums and I have started to vision myself getting in to the nook color honeycomb idea.
But a few questions first...
How well has it worked for anyone who has tried, is it a daily driver yet or too many issues? I have a SGS captivate so I am not too worried about having to mess with it before it works and I can use my phone to access email and all that.
But is it quick and snappy or will I feel like i'm using an underpowered device after using my phone.
And battery life, is it good, acceptable, or what?
Sorry if these have been answered somewhere else i tried to find the answers, but it's getting late and I have work yet to do tonight.

I installed it to emmc..over clocked it's still sluggish. Kinda cool but not a keeper to me.my droid x blows it away on performance. I will be back on phiremod beta 2 soon. Honeycomb is fun to tinker but not primetime. Remember it is not from aosp..missing features. It is amazing how good it isconsidering.

Well...its very promising for being in the early stages of development

i use honeycomb as a daily driver and if you install V2 on the emmc from samuallhaff(not 100% sure of his username off the top of my head) it runs smooth and it is really clean
i get the stock all day battery life(mainly it just sits in my bag when im in class but i have wifi always on so i dont disconnect from my schools wifi) and web browsing is amazing(it doesnt have flash though not a deal breaker though imo)
just dont use live wall papers and set CPU because they drain battery life faster and they diminish performance big time

I just realized that you are running HC from your SD card.
No, if you format that SD card, you lose HC. It actually mentions that in the procedure you linked in your original post.
The reason you only see 115MB on the card when you mount it on your Windows computer is because Windows can only see the first partition, the boot partition, that was written to that SD card as part of the procedure you followed. The rest of the space is taken up by partitions Windows can't see without help.
So if you want to continue to run HC off the SD card you have to dedicate that SD card just for running HC.

SD Card Partitions
while installing the image 3 patitions will be written on your sd-card.
1) root partition
2) honeycomb
3) fat32-partition
to use the full size of the sd-card use a partition manager to extend the fat32-partition.
installed apps can than transferred to the fat32-partition

i was wondering if i put honeycomb on my nook color, not on the sdcard, how would i do it. The instructions on that site only says how to make a bootable sd card. And i was using HC on a level 4 sd card and it said that u need a level 6. But i was still able to get it to run. The honeycomb on the sd card level 4 was pretty slow. i was wondering if i got it on my NC, would it be faster. If it would, can someone show me how?

Just follow the instructions here:

Nope lots of lag still. Its ok not complaining. Lots of fc in dolphin too. Back to phiremod 2.2 for awhile.

You have to remember that the Honeycomb that was Ported is the Preview Release, think Demo version. It wasn't ported from (pretty much)scratch like Froyo was. It is more of a Rom hack. For a better performing version we have to wait for Honeycomb's Official Full release. In perspective, it's amazing how much deeper-blue got done with just the Preview image.

Not picking on you but it's actually 4 partitions.
1=Boot (Basically redirects to the Android on the SD)
2=System (Holds the main OS files of Honeycomb)
3=Data (Where all you're settings and other data are)
4=SDcard (This partition is used as a stand in for a Physical External SDcard)
Also the easiest/simplest way to access the 2, 3, and 4 partitions is to use linux. Burn a LiveCD if you don't want to Install, although Ubuntu can be Installed without Partitioning or other such normal 2nd OS needs. Just get the Windows installer from http://ubuntu.com

SD Card and Honeycomb 3.0 v4 image
I've been looking for an answer throughout the forums on this question but can't seem to find anything. The problem: I used the Honeycomb v4 image with WinImage. The SD card was originally 8 GB. The image file is 4 GB with approximately 600 MB or so of free space. Missing: 4 GB that was on the card.
1. Can I use a utility under Windows to get the free space allocated on the SD card that remains? If so, how?
2. Is there an option with WinImage to allocate the additional space on the SD card as free space and include it as part of the image that is being written to the SD card?
3. If I need to restore my SD card back to 8 GB, can that be done in Windows Explorer (not sure that Windows will pick up the full 8 GB as I haven't tried that yet).
Thanks.

Ohh, you have that problem. Don't know where you've been looking but that has been asked and answered many times. The problem is that when you install Froyo or Honey to the SD it makes 4 partitions like I listed above, but Windows can only see the First Partition and only Formats the First partition. The easiest way to fix is to put it in UnRooted Stock and Format it from Settings. If you don't have that you can Burn a Linux or GParted Live CD and Format it from their.

What is uNooter?

I just got my Nook Color and am looking into how to go about rooting it for CM7. I checked out CM's Wiki page on it here and it mentioned using uNooter. I haven't read about this tool anywhere else and Google searches for it turn up practically nothing. Is this not the right tool to use? The forums mostly seem to mention ManualNooter, Auto-Nooter, etc. Also is it possible to flash CM7 on the internal memory and avoid using an SD card altogether?

Never heard of unooter and I've been reading theses forums since December. Auto mooter was to root the older firmware 1.0 ,1.01,and 1.1. Manualnooter is for the newer froyo firmware.

Rooting stock is not required to install CM7.
You simply need to create a Clockworkmod recovery microSD card and you can then flash CM7 (which is pre-rooted) from Clockworkmod.

Thanks. I figured this would be relatively easy compared to rooting and putting CM7 on my EVO but reading on here there seemed to be a few different approaches. Will that method allow me to flash CM7 to the eMMC, and after that point will I no longer need the SD card to boot? I ask because I don't have a card on hand and am considering backing up the contents from my phone's card and using that.

Correct.
You only need the SD to install a bootable CWM then you can flash CM7 from that. After words when CM7 is installed to eMMC you are able to use Rom Manager to install CWM to eMMC as well, so everything will be set up on the device's internal memory. SD is needed only for the initial boot of CWM to install CM7.

Thanks. From reading around it seems you can't use a phone or the Nook to mount the card and write the image, so I'll have to buy a reader and might as well get a card for the Nook at the same time. Since I'll be flashing CM7 to eMMC does it really matter if I get a class 4 or above card like many suggest? I'm not sure what's in my EVO but that is my benchmark. Class 2 seems to be what comes up in searches the most.

The general consensus it's to stick with Sandisk SD cards for the Nook. There are others that work as well but Sandisk it's pretty much a guarantee of zero issues. You can usually score an 8 GB class 4 Sandisk at Wal-mart for a Jackson.

I was the one that put together uNooter after being contacted by the individual that maintains the CyanogenMod wiki. They wanted a universal Nooter that would only root the device, install Superuser, ADB, RomManger, and work on all versions of the NC software. They asked that it be called uNooter. It is not released anywhere else, so that is why you did not see any mention of it on a Google search.

That information is really only relevant to running a ROM from the SD card. If you're only using the card for storage, or to get CM7 on eMMC, manufacturer and card class don't matter.

I wrote my image over USB to a card in the NC without a card reader. I've seen wiki guides saying there's a greater chance of the write getting interrupted, rendering the card unusable at least in the short term, but it worked for me. It was only when I wanted to revert the card to storage that I ended up needing a card reader. The links in my sig have a little more info about using the NC as your card reader, but you're probably better off just grabbing one.
Also, while CM7 does not require an SD card, many apps do. Your experience will be somewhat limited without one.

Great to hear directly from the source, thanks! I'm surprised more people don't point to your tool on the forums given that it's right on the CM Wiki. At this point I'm a little confused about the various approaches to do this. Does your tool install ROM Manager directly into the stock Nook interface, and then I flash from there, versus booting CWM off the SD as people mentioned earlier in the thread? Sorry if that's completely off-base.

Yeah, I thought about this as well and figured I'd want a full-time card for the device so I ordered a card with SD adapter. I figured the specs didn't matter at all for a data card but picked up a class 4 Sandisk anyway.

I received notice this past Monday that the cleaned up version of the CyanogenMod wiki was online, so not a whole lot of exposure for people to talk about it. I believe the old wiki had listed the different Auto-Nooter and Manual-Nooter that went with each software version, thus taking up a lot of space and confusion. AN and MN are more tailored to people that want to stick with the stock software, but enable full Android Market access. People that want to go from stock to CyanogenMod don’t need all the extra software that is bundled with AN and MN just to be able to flash CyanogenMod. By eliminating all the version specific software I was able to create a version that would work on all current, and hopefully future, software versions.
Yes, my versions will install Rom Manager directly into the interface. You would then allow Rom Manger to install CWM Recovery, and then you can download and install CyanogenMod from the device. You could also take a full backup of your current stock rom. Using uNooter or bootable CWM will both get you to where you want to go, it is really up to you on how you want to get there.

Instructions for installing CM7 to the eMMC using CWM on a SD card (which can later be reformatted for storage) is in this thread: http://forum.xda-developers.com/showthread.php?t=1030227.

GMPOWER and bigbob23: Thanks for the info, that was exactly what I needed to clear everything up. I suppose backing up the stock ROM would be useful in case I ever needed to restore it for warranty purposes or anything. I'm not sure which approach I'll go with, my SD card came today so I'll be reading over both techniques and giving one a shot!
Thanks again.

I went through the process with uNooter as outlined on the CM Wiki and it went perfectly. The only thing was I had to use SD Formatter and the earliest 0.1 version of Win32 Disk Imager to get the image to write to the SD card. Not sure if that problem is specific to Win7 64-bit but maybe I can mention it on the wiki.

I am glad that you got everything to work right. I think the problems that you might have experienced are more associated with win7 x64. My replacement laptop with win7 x64 will not be here for another two weeks for me to test it on, but in the past I have had to use Unlocker almost every time to unlock the usb drive before I could proceed with flashing using Win32 disk imager. On my current windows 7 x86 setup, I have yet had to use Unlocker to be able to flash an image with the win32 program. HERE is a post with people having problems in the past with win32 disk imager on win7 x64, they took the same path that you did with Panasonic SD Card Formatter to fix it.

I guess this worked for the latest firmware of 1.2.0? (I am about to root one soon!) thanks in advance!)

If you see "Read Forever" when booting (stock) then "Yes" you have the latest firmware.

ADB after uNooter?
Above, GMPOWER mentioned ADB as one of the items uNooter installed. I've rooted with uNooter in part because *nothing* *else* I could find would actually boot on my NC and in part because I liked the idea of a relatively minimal root. I figured I could then push any apk's I wanted to add with adb.
Unfortunately, that doesn't seem to be working. I used "NookColor Tools -> All Settings -> Development" to enable USB debugging, but 'adb devices' shows nothing. If I plug in my G2 with CM7, adb finds it just fine, so I'm pretty sure I've got the computer side of things working. Any hints about getting the NC to play nice?

[Q] Nook HD, CM 10.1 w/ CWM earlyaccessv4 - How to diagnose mysterious reboot(s)

Hi All,
I have a Nook HD, recently purchased and then updated to BN 2.0.6 firmware during the BN registration process. I used the sdcard-cwm-early5.img.gz as referenced in Verygreen's post here to create a bootable CWM SD. I then installed the CM 10.1 build posted in thread by Bokbokban here. Finally, I installed latest gapps from goo.im. All seems to be pretty good, excepting that sometimes, seemingly randomly, the device will reboot itself, at which time it bypasses the SD during boot and goes straight for the stock BN rom on the emmc.
Any ideas on how to proceed? I haven't seen a pattern in the reboots yet, so I am not sure what may or may not be causing them. While I'm not exactly a newb with all that is involved with rooting/flashing various android devices (I own 5 of them), I could use some guidance on how to troubleshoot or diagnose problems like this.

I am confused. You used an HD+ image from verygreen and an HD ROM from bokbokan. How did you make that work? They should not have worked.
But if you really only used HD files, the reboot problem is probably the brand and class of the SD you used. It needs to be SanDisk class 4. We have that problem a lot on the HD+. It is cause by a kernel panic when trying to write to SD.
The solution is to get a better SD or use bokbokan's new Hybrid SD setup that puts /data on internal memory so SD speed does not matter.

Thanks for your prompt reply. To be clearer, I did not use the HD+ image, but I did use the CWM image Verygreen posted, 'sdcard-cwm-early5.img.gz', as that version supported using CWM to read .zip's from /emmc (in other words, those that were downloaded via BN stock browser).
At the risk of sounding like I am second-guessing you, I think it's worth noting that I had no trouble with many things related to writing to the SD card: writing the CWM image, booting into CWM from the SD, writing the CM10.1 image onto the card, booting from the 10.1 rom, etc... So if it is, as you say, the card having write issues and causing a kernel panic, I'm wondering how I can prove that. I will check the kernel logs when I get home.
I'm using a Sandisk 'ultra' class 10 16gb... I get that 'class 10' generally means 'crappy for small random write requests', but I've had good luck with this particular card on other platforms that are sensitive to consistency of write speeds (G2, Nook Color). However, I'll try a class-4 Sandisk per your suggestion.
Follow-up question: I can't seem to find a solid guide that shows how to install to emmc... is that a new frontier for this device? Is it just that nobody has bothered, or is there a problem with original bootloader supporting that?

The internal bootloader is locked down pretty good. Some day someone will be able to break it, but for now no one has.

Btw, I have had really bad results with my San disk CL 10. You may find other cars will work better.
