can't boot nook

need help can't boot my nook now (16gb Kingston class 10)

Grab the installer image here:

http://nook.handhelds.ru/sdimage/gen...rd-v1.1.img.gz

it's a ~9M image that would unpack into ~130M disk image.

(OK MADE DISC IMAGE, NO PROBLEM) Used WinImage

Write the image on your SD card. I tested with 2G and 8G cards and both worked.

Any uSD card of 1G or bigger in size should work if it is recognized by your nook.

After done with writing, eject and then insert the uSD card into your computer.

Now download a CM nightly build from here http://mirror.teamdouche.net/?device=encore

Or get my last build from here: http://nook.handhelds.ru/cm7/

(GOT CM NIGHTLY and put zip on) Easy.. AND DONE

Put the file to the SD card (there is only one partition). Don't change the name of the file.

unmount the uSD card and insert it into the nook. Yep....

Boot from this SD card. It'll boot and will update you on progress....

Can't boot!! What the heck, I did this with a 8gb class 6 earlier.. worked just fine.. What am I doing wrong.. thanks so much

Of course if I remove the sd card it boots fine..

Put in back in.. Nothing..

I have reformatted card, re-imaged, taken card back to store.. Bought another card.. Exact same problem. I must be doing something wrong! Please help
[Nook Color Android Development] DizzyDen:
Read further back in the thread... this has been an issue with 16 GB and larger uSD's.... to make it work we have had to create an 8 GB or smaller card... install CM7 then use something like winimage or win32 disk imager to read the 8 GB card... write that image to the larger card and use something like EASUS or Mini Tool partition tools to extend the 4th partition to use remainder of the card.

We have narrowed it down to the first mke2fs command failing... but haven't found a work around yet... other than above.
[Nook Color Android Development] acme2ajax:
Hi Kingblind....I faced the similar problem......So you can do what i did:

1. Download the "CM7 SD Bootable, w/ experimental BT working" image from this thread: http://xdaforums.com/showthread.php?t=989637

Its a 2 gb image, so it should write fine on your card.

2. You can extend your sd card partition to the remaining 13-14 odd gb using (I use) easeus partition manager

3. Boot.......You will find that the NC boots to this image :) Enjoy!

4. Additionally, you can update this image too.....download a nightly/RC of your choice

5. Follow the update instructions given by verygreen in the initial post:

I have used this method and updated till the latest nightly....facing no problems whatsoever...

Hope this helps.... :)
[Nook Color Android Development] BlizzofOZ:
Ugh... I'm still having the same problem. I'm stuck at the arrow cicling the Anroid screen. I've tried reformatting and different CM7 nightlies... just not working.

I'm confused because on my first attempt, it worked.

What could I be doing wrong? Something corrupted?

Removing the SD and rebooting, I am able to get back to the original autonooter version.

:confused:
[Nook Color Android Development] kingblind:
thanks, I'll give that a try!!

So, I wonder what are the zip file names you are adding to the boot partition when it stops to load?
[Nook Color Android Development] kingblind:
I am trying your suggestion first.. I have a 8gb sd that works great.. made an image of it.. doesn't boot.. hmm.. Must have done something wrong.. GRRRR.. will try again.
[Nook Color Android Development] quinxy:
Just FYI, I think class 10 is a no go. My Patriot LX class 10 (8 and 16 GB varieties) would boot and run when I imaged a working system I made on a class 4 (to work around the install problem), but it wouldn't stay running long. The file system would revert to read only because of some error and the entire system would start failing. I switched to the cheapo PNY class 4 which cost me $9. The biggest surprise of all was to discover that the class 4 card I shunned actually performs at 12 MB/s write and 84 MB/s read (class 10 speeds), within 5% of the class 10 card I paid triple for.

So, please, try a cheapo PNY class 4 before you go insane.

[Nook Color Android Development] kingblind:
ok, downloaded the 2gb img.. used win 32 disk imager ... still won't boot.. what in the heck!!
[Nook Color Android Development] kingblind:
ha.. I have a class 6 (8 gb) works like a champ.. I do feel like I am going a bit nuts.. crap!! this card wasn't cheap!!
[Nook Color Android Development] DizzyDen:
I haven't been able to have the autoconfig work on any 16 GB i've tried... no matter what class or brand.

I run my duped and expanded image on my Wintec C10 16GB as my daily driver and have very few issues... Currently putting the image on my no-name C6 16GB to see if I have the same issues... in benching both cards... the C10 is in fact faster... but I think the C6 would be fast enough to run....

But, your advice on the PNY is appreciated as well.
[Nook Color Android Development] geebake:
Just an FYI, I'm using a Class 10 card and it's working great. Not completely sure of the details but the card says Patriot MicroSD HC (10). I originally created the image on a Class 4 card and then backed up/restored to this card as an experiment. I guess I hit on this totally by accident, but all I can tell you that it runs great. Definitely snappier than the Class 4, though it sounds like you're getting faster throughput with your Class 4 card anyway.

Check that. A quick check of the specs shows this as an LX card as well. Probably the same exact card. Maybe they're not very consistently produced and I got lucky.

[Nook Color Android Development] quinxy:
Thanks for the info, maybe I just have a defective card. I thought I tried both of mine, but since they look the same I might have used the same one twice and not realized. So no force closes for you? I mean, sure once every few days, or something related to a particular app's bugginess but otherwise no problems?

On an unrelated note... anyone know how to make the sdcard partition which is already formatted fat32 visible in Windows? Windows Disk Manager just says it can't touch that drive because it is perpetually "out of date and the disk management view needs to be refreshed". Tried assigning a drive letter to it via other means as well and nothing would work, in either XP or 7. Obviously it'd be nice to easy be able to add/remove/modify files from this partition, and it's already in fat32. Is there something screwy about the partition table? I don't have a Linux box handy and can't find any tools for Android.

[Nook Color Android Development] Lamar720:
Ok I have a question. How do you side-load apps to the sd bootable so you can install them?
[Nook Color Android Development] bobo12:
I'm seeing the same problem. My solution was to boot into Ubuntu (use a livecd if you have to) and then copy and paste the needed files from there. This is not the ideal situation though.
[Nook Color Android Development] quinxy:
My temporary solution is actually easier than this, but slower. I use Ghost Commander with SMB plugin to transfer the files from my NAS (or Windows box). Still would love to unhide the sdcard partition, that'd be best as an option; makes me feel stupid not knowing why I can't make it visible, I know the solution is easy!

^ Quinxy
[Nook Color Android Development] DizzyDen:
Actually the problem is that they are all configured as primary partitions... Windows will only see the first active primary partition... to see the other partition... you would need to go into a partition manager and make the other fat32 (4th) partition the active partition... but then you'd have to change it back before putting it back in the nook.
[Nook Color Android Development] MajTom:
Have you checked into PuppyLinux? Great small footprint that you can write to a CD or SD card. If your PC boots from either, it starts up in linux. I just put my micro SD card into a usb adapter and plug it in. Puppy will see your hard drives and the usb/sd card. I just drag and drop since it sees all 4 partitions.

How do I sideload apps to install on bootable sdcard

How Do I Get The Unused Space Back

So I successfully installed and am booting with the CM7 RC4 build - but I can't seem to be able to load media on the SD Card. I used a 16 Gb card - how do I get the unused space back (or be able to see it in Windows)?
[Nook Color Android Development] geebake:
I get a force close every once in a while, but no more than I did with the Class 4 card.

I have the same issue with partitions - or similar issues anyway. I don't have access to a linux machine at the moment either and it's a real headache. I did come across a utility called Easeus Partition Master that has helped with a few things, but not all. Maybe it can help you out. Google it.

[Nook Color Android Development] dweezilz:
OK...feeling dumb here, but I'm trying to update to the newest nightly for the first time and my boot partition only has 24 megs free thus the 80 meg zip won't fit on it. I'm assuming that's where the update zip goes (1st partition). I'm guessing I can increase the partition size, but I'm also guessing I'm missing something since that wasn't mentioned as a possible issue (ie boot is too small). No unnecessary files that I can find on there either. I'm guessing hidden files I can't see are taking up the space??
[Nook Color Android Development] stilger:
Well I did some testing today. I built a brand new sdcard and ran it on the two nook colors I have access to. I still had lots of FC's. I have now tried cm7-sd on two different nooks with two different sdcards.

After building the new sdcard and having problems I decided to test it on emmc. (First emmc install. I was a little reluctant. I guess I should not have been). I followed the dualboot instructions thread and moved my regular nook stock install to the secondary location. Installed the multi boot menu so I could choose normal,alternate or recovery. Then installed cm7-37 nightly using emmc recovery. (Thats the reason i moved stock to the dual boot location so I could use regular recovery and update scripts).

Anyways........... I have not got 1 FC in the 5 or so hours I have had it installed and been tweaking it!!

Hopefully I just had bad luck with cm7 on SD. The experience while being on SD was enough to make me not want to run cm7. I am glad I stuck with it though, the tablet tweaks are enough to make me want to use cm7 over anything else.

I just thought I would share this in case anyone else has problems running cm7 from SD.
[Nook Color Android Development] stilger:
I had this problem once when the sdcard would not unmount cleanly when copying files to it. The next time I plugged it in Windows asked to scan it for errors. Once it was done there was space missing. It appears there was a hidden directory with parts of the file I was copying to the sdcard. Once i deleted the directory all the space came back.
[Nook Color Android Development] Xhorder:
Is there a way to use the Dual Boot utility posted in another thread along with this?

Being able to easily boot either SD or eMMC, and also be able to update CM7 would be awesome.
[Nook Color Android Development] damayor521:
I can verify that the boot menu works. I use it to easily flash nightlies onto my CM7 SD by booting into recovery from the boot menu.

[Nook Color Android Development] mrmark93:
I have been using this SD card setup since the day it was made available. My CM7 on SD doesn't ever FC on me. It is speedy when running OC @ 1.0Ghz and other than me knowing it's running off of SD, it runs as flawlessly as if it were on EMMC. I ran a performance Quadrant of 2200 for kicks. I use a 4GB class 4 San Disk--one I had laying around. Personally I'm waiting to see what goofyness B&N comes up with before I move CM7 over to EMMC as I have no other reason to do so with my SD setup. I'd guess your SD cards are your issues-the NC seems to be a bit picky about those.
[Nook Color Android Development] dweezilz:
Fixed it. There was a hidden directory called .trashes and for some reason it retained the ORIGINAL CM7 zip!! Once I deleted that, all was well...back to 100 megs!
[Nook Color Android Development] :
Same issue here, but I have not installed to emmc yet.
[Nook Color Android Development] Skater4599:
Hi all, I'm new to the Nook Color, but not android or CM7. Anyways I opted to use this tool to keep my emmc stock, But i'm having a problem. I got CM7 to boot and everythings great/fast but my SD card says it only has like 67MB free, my SD card is an 8GB, I was under the impression i would have more free space to put stuff like music/pics/videos and what not too, is this not the case and i will need to install to emmc to use it that way? Or did i do something wrong during install? Any insight is greatly appreciated, thank you!

Also am i able to use any of the 5GB internal storage while using CM7 this way?
[Nook Color Android Development] docfreed:
OK, I had exactly this issue and here's how I solved it.

1. Download and install Easus Partition Master for Windows[PMW] (it's free).

2. Stick your SD Card into your PC and start PMW - you should see your SD Card and probably 5 partitions - Partition 4 [ showing about 39 Mb ] is what you want to resize. You will note that there is also unallocated space - probably about 5+ Gb

3. OK - you must change your 4th partition so, a) make it active - by doing so PMW will tell you that must reboot your PC - don't worry it's safe so just do what it says. i

4. When you are back running start PMW and make certain that partition 4 on the SD card is active and primary. Then you can resize it to reclaim the remaining space.

5. Finally, go back and make Partition 1 - (this is the actual boot partition) - active

6. Insert the SD into the Nook and viola - you're good to go.

As for using the emmc, I use it easily - just download Astro File Manager and install (free from market). Once you run it you will be able to see emmc and within you will see MyFiles, a directory that BN has in emmc - this is the directory that you can load stuff into. Just connect your Nook to your PC and on the NookColor drive you will be able to see the emmc subdirectories and move files onto them (you will have to have the Nook connected via USB
[Nook Color Android Development] Skater4599:
This is super helpfull, Thank you!!

I actually already have Easeus partition manager on my PC, I'm gonna do this right now, thanks again
[Nook Color Android Development] khaytsus:
My 8G card was partitioned right.. 100M /boot 500M /system 1G /data the rest "/sdcard".

I suspect you're looking at /boot if you're seeing 67M free.
[Nook Color Android Development] Skater4599:
Actually you are correct, the partition was labeled as boot, but there were no other partitions in windows that showed up, are they hidden or do I need to mark them as active or something before i can use them to store pics/vids/music/books etc?
[Nook Color Android Development] :
Dam sd cards. I was having major performance issues, FCs, freezing, etc. with the first sd card I tried for running CM7 (class 4 and 8 gb). I then switched to a different sd card made by a different manufacturer (rated the same - class 4 and 2 gb), but the rom is running way better now. Go figure.....
[Nook Color Android Development] dweezilz:
Those having issues with FC's after updating (or before), I had the same issues. Market FC, gmail FC after updating to the newest nightly (38?). So...even thought it was slightly painful, I started over. Formatted the card, started fresh and guess what. Perfect so far. No FC's, all fast and excellent. Even video that's the proper resolution plays with HARDWARE acceleration as far as I can tell. Audio in sync and no stutters!! Over-clock kernel working perfectly and also SD card partition 4 sharing working just fine with internal Eclaire rooted stock. Hope this stays as stable, but this is working amazingly well now!!
[Nook Color Android Development] quinxy:
Anyone know how to enable USB access to the filesystem? I am using samuelhalff's app to do it but he mentioned CM 7 supports it natively, yet I don't see a native setting to enable it.

^ Quinxy
[Nook Color Android Development] japzone:
Generally Windows won't see the other Partitions because /data and /system are using the Linux format "ext". There are programs to help but personally I just use Linux to do all my Android work, as it will read almost any format and using linux with Linux-based Android is just less stressful in the end.

I recomend you get Ubuntu. It's pretty easy for linux newbies and comes with many useful programs and even more are just a Few clicks away. If you use the Windows Desktop installer (aka: Wubi) it installs Ubuntu to a Virtual disk instead of partitioning your drive. When you no longer want Ubuntu just go into Windows and uninstall it like any other program, no fuss or wasted Harddrive space.

Now that CM7 is stable I'm starting to shift to make it my default ROM.

I was just wondering about something.

What are the Pros and Cons to installing the OC Kernal?

[Nook Color Android Development] verygreen:
Well, the OC kernel is faster.

The CPU would also draw more power so the battery would be spent faster (possibly, depends on usage patterns).

The nook could be used as a hand-warmer too (just joking on this one).
[Nook Color Android Development] yazyazoo:
I just loaded verygreen's last CM7 build from his site. I really like this version. I am going to OC and loaded it up.

Should I OC in Settings -> Cyanogen Settings -> Performance and change the value to 1100 or should I use Set CPU?

I have used Nookie Froyo with SetCPu and didn't know if there was a difference in what I use to OC the nook?

Also what setting do you choose as in performance, ondemand, etc? Are these jsut preset OC values that you can customize to your choice?

Thanks!
[Nook Color Android Development] verygreen:
Actually it's somewhat outdated and now that there is final CM7 available, you probably better use that one as it probably has certain fixes and such.

I think these questions are answered in other CM7 threads. I remember you can't use certain setcpu features with kernels distributed for CM7.

This is a dumb question but i just wanted to confirm that the CM7 stable works on the microSD card -- right? Thanks!
[Nook Color Android Development] Skater4599:

[Nook Color Android Development] virajss:
I second that. CM7 stable is working very smooth on my 8GB Class 6 SD.

Thank you very much verygreen
[Nook Color Android Development] :
It depends on the microSD card.

With some you get terrible results (poor performance, FCs, etc.). With others it runs great.

In other words, CM7 is now very stable but is only as good as the hardware.
[Nook Color Android Development] bagelicious:
Looks like I ordered a crappy one off Amazon.com then. I went ahead and installed CM7 per the instructions in the OP and I am getting forcecloses everywhere. I even tried to use the overclock kernel to 1000 and 1100 as someone mentioned that fixed their FC's but it didn't help mine.

For the record, this is the microSD I bought incase anyone else wants to avoid this: http://www.amazon.com/gp/product/B0026L7DG0. I would like to find an 8gb card that is verified to work flawlessly with CM7. Any suggestions?

Verygreen,

Im new to this booting from a sd card, my nook is currently autonootered 3.0, Now I would like to get BT working.

I dont want sound like a smarta** but in your first post you repeatably go back and forth from a SD to a uSD.

Is there a difference Im not aware of?:)
[Nook Color Android Development] xdabr:
34Ford, "u" is an approximation of the Greek letter mu, and means "micro". Since all the Nook Color takes is microSD cards, that's all anyone is talking about when mentioning SD cards... (microSD cards can be loaded into SD card adapters too)
[Nook Color Android Development] SCWells72:
Sorry for the cross-post from the thread on Dalingrin's OC kernel, but I'm running CM7 stable from SD card (trying to leave stock untouched) and don't know how to use ROM Manager/CWR with that configuration. When I tell ROM Manager to write CWR, it does so to eMMC (I think?), but since the SD card has boot priority, when ROM Manager tries to reboot into CWR, it really just ends up rebooting into CM7 on the SD card. How can I use ROM Manager/CWR to install a new ROM on an SD card installation?

Thanks!

UPDATE: Never mind. I figured it out. Just follow the instructions here.
[Nook Color Android Development] quinxy:
I've been getting what I assume to be file corruption using using my SD card verygreen install. Apps suddenly can't open the files they create any more (e.g., Quick Office and a crossword puzzle app). The files have proper permissions, ownership, and I can view data in the files with a text editor (though I assume the data is corrupted and that's why the apps can't open the files any longer). I'm not sure if this is related to CyanogenMod 7, the kernel, or the SD cards. I've seen it now on multiple kernel versions, multiple CM 7 releases, and multiple SD cards (class 4 and class 10). Anyone else having this? Anyone else know what to do?

Separately, anyone know an easy way to convert an SD card install into an eMMC installation? I would imagine it must be super easy, but not sure how. Was thinking about trying this to exclude the SD cards as the source of the problems without buying yet another one.

[Nook Color Android Development] danbutter:
I wouldn't be so quick to blame transcend for your issues.

You aren't going to find a "certified for CM7" card.

They don't even have a certified for WP7 card out that I know of (maybe they do by now...not sure). I think they usually use sandisk though.

For what it is worth I have the exact same transcend card you linked to (actually multiple cards bought over the last three years in the household) and they all work great in multiple phones and nook color running CM7 final.

You could have a bad card as that will happen with any manufacturer, but if you are really worried about it look around for reviews of these cards. SanDisk is usually on top.
