[Q] NookColor does not boot from SDcard

Hi,
I've ran into a snag that I can't seem to figure out, my nookcolor boots normally but does not boot from uSD. In the past I've always been able to find answers by searching but this time, nothing I've tried has worked. I've been using phiremod on the nook for quite a while and recently updated to v6.1.
The first time I rooted the NC, I used a uSD with autonooter 3.0 and everything worked great. Flashed to phiremod 5.2 and have been using CWR off of the emmc to update versions.
Today, I decided to try a new rom and wanted to start fresh with a stock 1.1. I popped in the CWR sdcard I had from a while back and it didn't work, the NC boots normally in to phiremod.
After remaking a bootable CWR sdcard several times and failing, I thought it might be a corrupted boot partition. So I successfully reimaged the boot and system partitions via ADB and I was back to stock. I thought I was good to go except what I've got now is a stock NC that does not boot from the uSD.
I've tried 3 different perfectly good uSDcards with autonooter, monster's rootpack, CWR sdcards, nookie-froyo sdcards... nothing works. Failbooting 8 times causes the NC to reupdate itself to 1.1.
Has anybody encountered this before or some devs can shed some light why it does not boot from uSD? Any help is appreciated.
Edit: N+power causes the NC to do a Factory Reset. Done this twice already.

This might work....
Look, I'm no expert at uSD's, but try this. Maybe your Nook thinks the sd card is an emmc partition. Try holding down the home button while booting? Like, hold the button and then power on. I hope it works for you. I know the pain as I have had many issues, too.

My guess is the SD Card is not mounted, try going into the settings and make sure the card is mounted. You may want to unmount it, and then format it. Then unmount it, remove it and then reinstall cwr onto the sd card again. If that doesn't work, try another sdcard. If that doesn't work it could be a hardware issue... it could also be an issue with your card reader, they have been known to break at inopportune times, try a different card reader.

+1 to the card reader issue. I have a perfect working cm7 build on my nook now, but it took some trial and error. The card reader on my computer looked like it was working fine, but when I would put the card into the nook it wouldn't boot to it. I finally did the same steps with the same card only this time using my phone (tp2) as the card reader plugged into my computer and it worked great.

It definitely was the card reader. Tried a different one and it booted just fine..
As a SDET by profession, it makes me sad I didn't think of this.
Thanks all.

Linux Issue
I know this is rather an old thread, but just in case someone has this problem and is running Linux (I'm running Ubuntu) here is what happened to me. After dd'ing the CWR image several times, I could not get the NC to boot to the sd card. I tried multiple cards and multiple readers, no joy. I thought perhaps something was wrong so I looked at the card in gparted. What I found there was that there was a 1mb of unallocated partition space before the CWR partition. I used gparted to move the partition to be at 0 position and it booted up like a charm.
Don't know if I was doing something wrong the command I used was
Code:
sudo dd if=2gb_clockwork-3.0.1.0.img of=/dev/sdd1 bs=1M
At any rate, if any other linux users run into this, that's how I fixed it.

Yeah, the problem is you put it on the first partition rather than the card itself. Note the instructions in the forum say device of card. ie: /dev/sdd

I also had an issue where I could create the SD card, and the Nook could see it, but it wouldn't boot from it. It turns out this was because I was using the internal card reader in my laptop to write the card. Once I switched to an external USB card reader, the Nook booted from the card just fine.

I've just come across the same problem.
I started two days ago with this: [ROMS]NEW! Dualboot Mirage CM7 / ICS CM9 Image for SDcard.
I liked ICS so much, I asked the developer how could I just stick with CM9?
He pointed me to this tutorial: Installing CM9 on Nook Color microSD.
It seems as though all the steps are going fine, up until step#10, where I am supposed to reboot INTO a freshly installed nightly.
I have Ubuntu 11.10 reliably running in VirtualBox. Plenty of memory and space.
I run GParted and view the partitions, and they are as expected.
I know Ubutu well enough to follow well-written directions.
The sdcard in my Nook is properly mounted - I think.
After reading this thread, I went to Amazing and bought a new SD card reader.
OH, and all this has been done on a new SD card, 8GB, class 4.
Hopefully it is due to an aging card reader. I'll get the new one in a couple of days and report back.
I really hope that's it!

Rather than a card reader, I use Kingston uSD usb stick adapters for my uSD card writing, and they've worked flawlessly. Just an option , if your new card reader doesn't solve your problem. The adapters were "dirt cheap".

[Q] Doesnt boot to Stock ROM

Can someone please identify/resolve my problem?
PROBLEM:
CANNOT BOOT TO STOCK NC 1.2 ROM
Whenever I try to boot, with microSD card inserted, I boot to ClockworkModRecovery. Inside CWM Recovery Console, version states it's 3.0.2.8. In ROM Manager, it says it's 3.2.0.1. (Because at some point in time, I tried to update it through the Rom Manager. It did say that it was updated successfully, but whenever I boot to CWM, it still says 3.0.2.8.
Whenever I try to boot, without microSD card inserted, I boot to CM7 Nightly Build 97. What appears is a green cyanogenmod logo followed by a cyan-colored "loading..." below, then a flash, then straight to the CM7 boot screen (the blue android on skateboard).
FACTS:
[*]I'm currently running CM7 Nighty Build 97 along with Dalingrin's OC Kernel set at 1200MHz (Which made it a lot responsive and faster, thanks to Dalingrin! ) at my NC.
[*]I have to remove the microSD in order to boot to CM7. If I don't remove the microSD, it goes to CWM.
[*]I don't know, I don't have, and I'm not planning to install --- ADB.
[*]My microSD is a SAMSUNG 16GB Class 2 microSD card--at least, that's what it says on the card--which came from a Red Sandisk packaging. Weird, I know. Just putting all the info here, maybe it'll help solve the problem.
[*]My NC came with a green dot on it's packaging. I was told it has something to do with the partitioning of it's internal memory, but from what I can see, my NC has 5GB of internal memory capacity.
THE STORY:
Before, I was running CM7 7.0.3 (Stable) on my nook.
With microSD inserted, I boot to CM7. What happens is there would be a flashing, cyan 'a n d r o i d . . .' text at the left side of the screen. Afterwards, the CM7 logo appears and boots to CM7.
With microSD removed, I boot to STOCK NC 1.2 ROM. What happens is a "Read Forever" logo would appear, then a colored 'n' logo, then 'nook color' logo, then home screen.
Then I found out that there's a way to overclock the NC but it requires installing nightly builds. At first, I was a bit skeptical of installing a non-stable build, but when I tried it out, man was I amazed. My NC got a lot faster. I installed the CM7 Nightly Build 97. But then, I found out that I couldn't boot to the STOCK NC 1.2 ROM anymore.
HOW I DID IT:
I followed this instruction to install CWM:
hxxp://mrm3.net/nook-color-updated-clockwork-recovery-bootable-sd/*
NOTE: I picked the 16GB link under "Clockwork Recovery v3.0.2.8-Old Nook Colors(not blue dot)" category since I have a 16GB microSD card and the other category "Clockwork Recovery v3.2.0.1-For new blue dot Nook Colors and Old Nooks" does not have a link for 16GB, only 1GB.
Then I followed this guide to install CM7 Nightly Build 97:
hxxp://mrm3.net/nook-color-how-to-install-cyanogenmod-nightlies/*
NOTE: I ignored the instruction "Only install if when you boot your nook it DOES NOT SAY READ FOREVER" and proceeded to installing the updated U-Boot 1.2 simply because I overlooked it at that time (could this be causing the problem?)
And this to overclock my NC:
hxxp://mrm3.net/nook-color-overclock-guide/*
NOTE: I ignored the fact that it says "Install 'update-CM7-dalingrin-OC-emmc-060911.zip'. " even though I was a bit skeptical. I did got skeptical a bit because I thought I should install instead the sd update instead of the emmc. But I proceeded anyway. (Could this be it?)
Can someone please identify what I've done wrong? Or can someone please give me a tutorial to fix it? Or at least point me to a tutorial that will fix the problem. I've been trying to find a way to fix it by myself by reading forums and blogs and stuff but I can't seem to find anything. I'm a noob, but I do know how to follow simple instructions. I'd really appreciate it if you can help me. :'(
*replace 'xx' to 'tt' to view the link.

You haven't done anything wrong, but you did get rid of your previous setup. You turned your SD card into a CWR bootable card, then installed CM7 to your internal memory. By doing this, you erased your stock 1.2 and replaced it with CM7. To get your SD card to stop booting to CWR, you can simply format the card. This will remove the boot files and it becomes a standard memory card once again. If you want your stock 1.2 back, there are threads here that explain how to revert back to stock. You might need that bootable SD card, however, so wait until you decide what you want to do before formatting the card.
Unless you have some reason to want your stock 1.2 back, I would suggest you just stick with what you have. It is what most of us are running.

Thanks for that. I was sure I didn't do anything wrong.
My reason for wanting to get access to my stock ROM is for me to 'Archive' my epubs. I have like a million of them, and I do read a lot. I cant find a good app to view epubs just like the stock B&N NC 1.2 reader... so if I archive those epubs, I'd be able to view them through the nook for android app. And yup, I've tried putting the epubs in the nook directory, it's still not reading it. That's basically it. If you guys can find a better way to view epubs like the stock B&N, I'm happy. Any ideas?
I'm hoping to try Phiremod as well in the near future, just so I can get a feel of which ROMs are the best. I've seen people running a ROM that still has the original 'Nook Color' status bar at the bottom and a dock bar on the side.
See it here: hxxp://w w w.youtube.com/watch?v=8d7ncguNjrE*
I think it's cool. If that build can run all apps in my CM7 nightly (I recently updated to Build 100), and also if that can be overclocked to at least 1.2GHz, I'll be so happy.
Please comment on all your ideas!!!

up up up up up up.

Persistent, aren't you.
There are lots of free apps that can read epub files. I downloaded the free epub of 'Phantom of the Opera' from some random web site, then looked in the Market for an 'epub reader'. One called 'FB Reader' was one of the first results. Opened the book fine, had lots of user-changable options and settings. Lots of other such apps available. Did this all in about 3 minutes using only my Nook with CM7 installed to internal memory. Took me longer to type out this post.

[Q] Partition Problems with VG's CM7 on SDCard

Hey all...
I realize there have been several threads about this general topic, but I couldn't find my issues specifically. First, thanks to all the developers for all their work. I've had a blast with my ManNooter'd Nook.
Issues:
1. Using WinImager to an 8 gig Sandisk card. As expected, the "generic.img" supplied in the thread created only one visible partition (for Windows) of about 117 megs. However, I'm not able to resize the partition using any of three different partition managers I tried. I'm doing this before I install CM7. As far as the programs are concerned, I have a 117 card, period. I've tried deleting all partitions and reformatting to the full 7.x gigs, then reimaging, but still no dice.
2. If I do go ahead and install CM7 with the default partition, it works fine and I can boot into the OS. It shows that I've got almost 6 gigs free, so apparently it created the FAT partition. However, I can neither mount the SD card in Windows to copy over the Gapps, nor can I access the card via USB through the Nook. If I put the card in directly to the PC, I get "need to format". If I run it through the Nook's USB, I get two drives popping up in Windows that both say "Insert Disk". So short of downloading from the Internet directly to the Nook, I can't access the card at all.
3. Say I DID want to settle for just downloading. How can I access the "boot" partition to drop Gapps there? I don't see it in File Expert.
Any suggestions for any of these? Many thanks.
Adam

Are you trying to resize the partition BEFORE you put the imaged card in the nook?
If I undrstand what you are trying to do... create a larger boot partition... you MUST resize that before doing anything else.... put the image on the card... resize the only partition on it... then put it in the nook for it to setup the remaining partitions and install CM7...
As for the rest... buy a cheap usb card reader... several internal card readers have issues accessing these cards for some reason.
If you wanted to settle (3) above... you would do the following in terminal emulator on nook or adb shell on computer...
Code:
mkdir /sdcard/boot (only have to do this one time)
mount /dev/block/mmcblk1p1 /sdcard/boot (has to be done every time... lost on reboot)
That will allow you to access the boot partition via /sdcard/boot directory.

Yes, I'm trying to do this in the order you've mentioned. Blank Card -> Image -> Resize attempt. Prior to Nook. However, I am using the internal card reader. If I can find the cheapo one I've got lying around, I'll try that and see if it helps. On both prob #1 and #2.
Thanks for the command line stuff. I shouldn't need to access that partition often, so losing it on reboot is no big deal.
Many thanks!

Don't use the internal card reader in the Nook. Use a USB reader on your PC, or any reader you might have built in on your PC.
EaseUs Partition Manager is free and can do what you want. That is how I resized mine when I was playing around with Honeycomb.

I actually just re-created my microSD layout with a bigger boot partition. Just make the first partition a FAT16/FAT32 volume and drop the files from VG's boot partition there. While you're at it, you might as well create the other partitions if you prefer to customize. A major gotcha for me was that the first partition had to start at sector 63, not 2048 as fdisk preferred.

In the "you've got to be kidding me" category, retrying the image/resize partition operation worked perfectly using my cheapo $2 card reader that came with a card I bought years ago. Neither the reader in my work PC nor the reader in my nearly new laptop would do this properly, and I used the exact same steps each time. Thanks for the suggestion, Dizzy.
My only problem now is getting Youtube on there. Twice during previous CM7 attempts, I tried flashing Gapps, selected a few of the apps to install including YT, and ended up with a bunch of "can't be found" errors. WiFi was up and running already. It installed Gmail and Talk about nothing else. This most recent try (after the successful resize and CM7 reinstall,) I selected nothing except the required Google Search. It installed without error, but now I can't get YouTube on there via the market.
Edit: I tried reflashing Gapps over itself. VG's recovery picks it up and looks to install it, but I don't get YT and it doesn't run the original setup screens again.
Any suggestions?
Thanks again for the input, all.
Adam

I assume you got your NC straighten out, so no more help, I guess.
As for the Youtube, you have 2 choices
a. Uninstall Market Updater OR reverse back to the older version of Market.
b. Sideloading the Youtube app.

Yep. Good to go on CM7.
I went ahead and sideloaded the version of YouTube I had from my ManNooter'd ROM. The newest version on the Market always gave me problems and didn't seem to want to play any videos. I'm also good to go here.
Thanks again for the help, all. Still can't believe the key was to use the crappiest card reader I could find.

New Nook HD+ will not boot from SD card.

I bought a Nook HD+ for the mothers day sale, booted CM10.1 from the SD card, and it ran fine for about a week. It ended up dying, so I had to exchange for a new one. Brought my new one home today, and it would not boot any of my bootable SD cards. I had 3 that worked on my old HD+, and none of them work on this new one. No clue, but thought I should warn you all. I'm now looking for a buyer of my brond new device as it's useless to me without root.

confirmed
my nook HD+ for the mothers day sale also has this problem. does the bootloader not boot from the sd any more?

I have two devices. My old one boots to SD very reliably. My new one is very temperamental. But it will boot eventually. For me it just takes many, many tries. I finally got it to boot, did a nandroid backup, then flashed the emmc CM10.1 and the emmc CWM. So now I never have to boot to SD again with it. All flashing can be done with emmc CWM.
Edit: If you want to stay with stock and still be able to flash my mods, you can just flash the CWM that gets put on internal memory (emmc) so that you don't have to boot the SD CWM anymore. I made a custom version (6028) for internal memory. You can get it here or here. That just means it cannot be auto-updated to a new stock. After you install this internal memory CWM, you get to it by holding the n and power keys together on boot and releasing after a few seconds. It should boot to CWM. If you want a new update to stock, you would need to flash it manually with CWM. If you do update, you will need to re-flash the emmc CWM again immediately before re-booting since the update replaces CWM with stock recovery.

My first one would boot almost every time. I have booted this one at least 30 times, and still a no go. Do you have more luck with the power cord in, or out?

Did not matter. Mine would not even turn on with the SD inserted. I just had to keep hard powering off with the SD inserted. You might try reburning with the newest Win32DiskImager from my link. Someone else said that helped.

I know, I have the same issue. Some devices are just finicky. One boots right away and one balks. A warranty exchange maybe? Can't tell them really why though.
I got a brand new HD also and it boots fine. I think the slot hardware on the HD+ is really unreliable. I don't think B&N changed the booting software. Maybe try cleaning the contacts? Using a different card?

I literally just got this one on a warranty exchange yesterday. I don't think they will give me another. It's been 2 weeks since I bought my first one today. I may just return this one. It's more hassle than it's worth. I'll probably end up buying a chromebook in the end (for Linux)

It was worth the $190 I spend on it if it was rootable, but I'm not buying one at $270 later. It was worth the run, but not that much cash.

great. I test again today. Another 8G Adata class4 microSD works! The newer shows more choosey about sd? Thanks, leapinlar!

Thanks for the advice! After about 30 tries I was finally successful getting mine to boot up with a Samsung 8 GB card. For those having trouble: keep trying! The time that worked I both blew on the contacts and inserted it particularly hard. Felt like I was fiddling with an old NES :laugh:
Never was successful with a G.Skill 8 GB card.
FWIW I purchased mine yesterday and it was manufactured in November, 2012 according to the Nook internal diagnostics screen on first boot.

Well i have been trying with 4 different cards and no one worked.
Any trick or procedure to make this work?
Will the 1gb image work better than the 4Gb or it will be the same thing?
Thanks

You can try my alternate procedure that requires no burning. Look in my HD/HD+ CWM thread and see the new procedure in item 1a.

Thanks! When i was reading that i was able to boot with the 1Gb card.
Now i am trying to make the backup and i think i will be ready to go.
To the new guys like me, keep trying and change the card. :good:

As others have mentioned, the boot problem appears to be tied to some hardware difference between individual units. I tried my SD card on a buddy's unit and it worked first try. Exact same SD card took 30+ tries on mine!

Not sure if this is helpful or not. I only have Verbatim 16gb cards, I bought them all at the same time. My HD plus boots every time from the cards they are marked HC. Worth a try if you have one in another device or can get one really cheap. I just got my Nook for Father's day so maybe they fixed the issue on the latest batch or maybe I just got lucky. I am not sure just throwing it out there for others to try.

Hello.
I did not manage to boot a few SD cards - until I marked the partition on the SDcard with the lba flag. I used Gparted ( a linux tool /distro for manipulating any kind of storage disks). I used Ubuntu for this. The process is very easy - boot in Ubuntu (even if you dont have it installed, it can be easily booted from USB(live USB), the process is described all over the web an is fairly easy.). If you boot from live USB, Gparted is pre-installed, find it in the dash top-left button will bring you a search filed.
Once Gparted is open, select the first partition of the SDcard, right click and apply.
This fixed it for me.
Ps What is LBA(form thr gparted site):
LBA is used by some commercial operating system boot loaders. The LBA flag indicates the partition should be accessed using Logical Block Addressing (LBA), instead of Cylinder-Head-Sector (CHS) addressing.

Me too! Mine would sometimes not power on at all, or sometimes power on but boot to stock, depending on what utilities I used to format and partition. After reading your suggestion, I first tried running Gparted in my Ubuntu VM under Parallels on my Mac, but that didn't work at all. Then I reformatted and repartitioned in EaseUS Partition Manager, and then used a Gparted Live USB image to set the LBA flag as you directed, and it worked a treat! Thank you!

I bought Nook HD+ 32GB during the father's day sale
I follow this thread http://forum.xda-developers.com/showpost.php?p=35811322&postcount=1, and downloaded NookHDplus-bootable-CWM-6028-for-stock-4GB-rev4-(05.15.13).zip
I then burn the img to a Sandisk 4GB Class2 micro SDHC I have lying around using dd on ubuntu
Just like the recent messages shown, I can't boot up my Nook HD+ using this CWM bootable Micro SDHC card
I even used linux gparted to set the lba flag, no go
After about 10 tries, it finally boots into CWM
So yes, just be persistent

HELP - Recovery of Nook Color.

I've decided to recover my modded Nook back to stock, but I haven't been keeping updated on the latest CWMs. I can't find which CWM and which Image files to use to recover my Nook Color back into Stock.

Anyone know where I can find another mirror for this site
Legacyschool.us.to

Go to my nook color tips thread linked in my signature. I have both the required CWM and instructions (item A15) there.

believe I have deleted partitions on nook color
First, thank you so much for all the work you and other do.. Here is my problem. My nook color will not boot (black screen) . I believe I have inadvertently mounted and deleted my emmc partitions using an sd partitioning tool. I have a bootable cwm card I use to at least boot the nook (color). I have tried to use cwm to format emmc, and then used all of your repair tools to attempt to recreate and repair my partitions, but to no avail. Reading your posts, I have come to the conclusion that I have somehow deleted/corrupted the all important third partition, because I attempt to repair partition 2, and your tool simply throws error and aborts. Everything I have tried so far has only been done through cwm off sd card, I have not tried to push anything through adb, as I don't have it at this time, but I wanted to know if this would be your suggestion before I went further. As many have said before, (but you have proven wrong) I have actually bricked this nook at this point. Other possibly pertinent info: cwm version 3.0.2.8 off sd card. When trying to format emmc using cwm, process reports done but then freezes required hard restart. I have tried many different things from you wonderful devs, but without getting my part 3 back, I am at a loss!! thanks so much for what you do, and your time!

once again, black screen, no response from any boot method. Not even a soft glow from screen.

If it won't turn on after flashing that zip that means you must have destroyed your partition table with that software. That is fixable, but not easily and not with any tools I have made. You must learn how to operate fdisk and repair it manually. You can make a bootable TWRP SD which has a terminal emulator program that lets you run fdisk to see what you have there. Then possibly you could reconstruct the partition table. But you have to know what you are doing.

Thank you so much for your response, sorry my response was so slow, I have a child now in the hospital. I have downloaded your twrp 2.1.8 bootable from a different thread. Is this the tool I will need? Would I simply copy your exe to my cwm disk and run it from there? I am relatively computer literate and somewhat comfortable using partition tools, but of course I will need specific instructions, your recommendations on partition size, etc. Once again, THANK YOU for your time, even bothering to assist me with this is GREATLY appreciated!

If you search the NC forums the partition sizes are listed. I am not sure where it is. And I think that version of TWRP has a terminal, but you may need a newer one.

I am so sorry for the delay in a response, I have had a lot on my plate lately, and not been able to devote much time to my little nook. Her is where I stand : booting from twrp (with terminal as you say) fdisk 1.3.1 installed on sdcard and opening in terminal. I type fdisk, and it will pull up the usage table. Here is where I run into trouble......... I type # fdisk -l to try and view existing tables, it only shows my sd card... I have tried every combination of command symbols I can think of. (#, ~, $, ~$, etc...) I thought I had a decent grasp of fdisk, but apparently not. Brother, if you can get me through this, you have a donation coming your way!! Not sure how to proceed, or if I even have necessary software versions. Thanks!!
