[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

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".
