[Nook HD, HD+ General] gogen:
I have to correct times for waiting. If I use uSD 4GB A-data class 6, safe time for me is about 8 minutes. I know the time 5mins 30secs was not enough. If I use 2GB SanDisk class 4, the time is shorter. Unfortunately I cannot find a reliable pattern for booting from SD. Let's say we increase significantly probability of successful SD boot if you wait for enough time.

Sometimes my Nook HD+ gets into state it is very reluctant to boot from any SD even if I wait for very long time. In this case just entering into Factory Reset menu and leaving it without doing a factory reset seems like it helped, so next boot with wait was successful. I had one unreliable CWM boot success (without waiting) after I did a Force Power Off from Stock firmware (holding a power button until device is switched off). The intent of this test was to skip Stock shutdown sequence.

Interesting is that when I am in CWM and do a restart and keep the same SD in the slot, it boots reliably into CWM again, but if I exchange the SD before I do a restart, it boots into Stock. I have to power off device and wait for 8 minutes so the second SD boots successfully.

I wonder if "Skip OOBE" described here <as a new user I cannot put an external link, just google for NOOK HD+ Skip OOBE> somehow affects the willingness of Nook HD+ to boot into CWM.

Anyway I can confirm that the uSD card can be prepared without burning/writing of the image with dd/winimage. It was fine just format uSD with SDFormatter, set the partition active and copy 5 files from .img file to the uSD. It is much faster. I use NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13) image from leapinlar's CWM/Extras thread.

I didn't see any effect when LBA flag on partition was set to On or Off.

Finally Got It To Read SD and Load

Formatted 8gb PNY class 10 card with SD format tool. Still no go. On third attempt, again booted to stock but after two minutes it rebooted on its own and then low and behold booted into the cyan. Loader and all was smooth after that. :)
[Nook HD, HD+ General] gogen:
Nice to hear that somebody can boot from class 10 card. It seemed to be impossible and general recommendation is to use class 4 cards.
[Nook HD, HD+ General] :
The Nook rebooted itself?
[Nook HD, HD+ General] jfenton57:
The Nook HD+ rebooted itself and then rebooted into the Cyano system after which I was able to load CWM and the ROM.

Works like a charm now :)

Absolutely boots from a PNY class 10 8GB card.

It rebooted itself while running stock and just sitting there? Or it was off sitting there when it rebooted? Or maybe off, but plugged into the PC?

[Nook HD, HD+ General] gogen:
Can somebody with pre Mother's day NOOK HD+ provide the original boot.img from CWM backup so I can compare it with mine? I am not sure if boot.img can be updated through OTA, so maybe my request is quite naive. But if it can be updated and an old device had got that update, it would have had also problem with boot after update to 2.1.0. The hardware cause of boot problems can be confirmed or refuted.

Thanks
[Nook HD, HD+ General] leapinlar:
The code sequence controlling the boot is in the omap chip firmware and cannot be modified by a ROM. Each update from B&N does generally update the boot.img, but boot.img has nothing to do with booting from SD. The booting sequence happens before it gets that far.

I am pretty sure it is hardware related, either the slot or some chips controlling it.

My stubborn device did it long before 2.1.0 showed up. It was loaded with 2.0.5 out of the box.

Pardon me for asking, has anyone brought up the make and model of the 'sd' card ? . Do not ever use a 'class 10' because they don't play nice with the tablet's electronics. . Use a SLOW sd card, and my personal favorite is the SanDisk brand. . Do not use winDoze to format the sd card. If you do it may be trouble. Google for a specific tester / formatter. . I use SDFormatter. Try to use plain old FAT format. . Sorry, looks like i am repeating what someone has already said...

Just got my Nook HD+ this weekend from OfficeMax for $99. Not sure if this was old stock or new, but using these instructions I was able to get CWM to boot on the first try. My SD card is a Maxell 16gb, class 10.
[Nook HD, HD+ General] :
99?!?! How did you pull that off? Argh I paid $200 with tax -_-
[Nook HD, HD+ General] dvschnk:
Major fire sale going on with the Nook HD and HD+. Officemax this week has the HD for 129 + a $50 gift card, and the HD+ for 149 with a $50 gift card....but the kicker is that when you ring it up, they deduct the price of the gift card already...so mine was $99 for the HD+. Some people have confused the poor folks at officemax even more by convincing them that they still get the $50 gift card, even though the "discounted" price is already shown....so there are some lucky folks getting an HD for 79 with a $50 GC, and the HD+ for $99 with the same GC....or a net price of $29 for the HD, and $49 for the HD+. The sale runs all week for anyone curious.
[Nook HD, HD+ General] grobiballon:
I am German and I am living next to Meridian, MS for the next months. This week I bought a Nook HD+ with intention of upgrading it to CM. The stock will not support German language :-/

I read all the instruction and I exactly followed them. I am not able to get it booting from SD. I tried "burning" an image and I tired the “new version” by formatting and setting active flag. Additionally I checked the LBA flag with gparted running in a virtual machine.

I bought two different SDs. I did have not known a CLASS 10 card would not be a good idea for booting so I bought a second one.

- SANDISK Ultra micro SDHC SDSDQUI-O32G-AW46

- SANDISK 8GB SDSDQ-008G-AW46A

It is not working at all - or I am doing something wrong. My procedure is starting be holding the power button for about 2s. Stock starts up. Shutting down by holding power button and pressing OK; or holding the power button a bit longer pressed. Removing SD and putting it back. And again... I tried it now about 50 times.

Is there anybody living in my area who has a working SD? I don’t want to buy masses of SD's...

I hope my bad English is understandable…

You may have one of the stubborn devices that does not like to boot to SD. I recommend trying to exchange it for one that does.

Booting from sd card

Hello,

I do not know if this can help but it is what works with my nook: with the tablet turned off, press "n" button, keep pressing it and then press the "on" button for three seconds or until you see the nook booting. It is the consistent as solution in my case.

my sd card experience on the HD plus

My HD+ was just bought on July 4th (32GB for $179 at walmart)

I had two samsung class 2 8GB cards that I had no luck with, then I dug around my office and found 16GB Sandisk "mobile ultra micro SD HC I" that booted on the first try. Throw that in the data pile

[Nook HD, HD+ General] ciris:
theres no need to go exchanging nooks when the simpe fix can be just using a different or smaller capacity sd card. I was having all sorts of trouble and tried a 2GB card I had laying around and it boots everytime no issue. Grant it I'm not using the 2gig card for running CM but just to boot to CWM to back up and install zips when needed. I have 4 and 8gig cards that Ive yet to test out so I may do that next,
[Nook HD, HD+ General] leapinlar:
I agree sometimes that is a simple fix, but some of the newer devices will not boot no matter what card you use.

I'm curious how quickly I should see the clockwork screen upon booting up in order to save me some time trying to boot and reboot over again? Should the very first Nook screen popup with the little Adobe Systems disclaimer below it before the clockwork screen, or should the clockwork screen be the very first thing I see?

I've rebooted the thing about 20 times so far trying various methods of formatting an SD card between two 2GB and one 1GB SanDisk branded card (even killed a 1gb SD card trying to do some partitioning on it).

I don't even care about rooting the device, I just want to side load some apps so I can run XBMC on it! LOL
[Nook HD, HD+ General] leapinlar:
It should first boot with a short plain nook symbol followed immediately by the cyanoboot logo. If the nook logo stays very long, it is trying to boot to stock.
[Nook HD, HD+ General] grobiballon:
Today I got a new one. I tried it again, and again. Finally I got it running by burning the 1 GB image “emmc-cwm-early2.1.img”. I tried it more than 30 times. Before it worked I played with the volume buttons while powering on. A few times just a black screen appeared where normally the boot loader logo should be. I had already given up, powered it on again and did not watched at it for minutes. About a few minutes later I recognized that it booted up from memory card.

I took a backup and flashed the zips. It is running now on CM.

Finally I tried again to boot from this SD card – sometimes it does, sometimes not. If it is booting from SD once and I am choosing “reboot” it will bot again from SD. When I remove the card, and put it back, it does not boot anymore.

Finally I did it with a 8GB microSDHC SanDisk class 4.

I did not expected that it would be that hard to get it running.

Thanks for support!
[Nook HD, HD+ General] espylacopa:
Yeah I've tried about 40 times so far and have no had any luck with the three SD cards I've tried. I'm thinking of trying an 8gb Patriot mem SD card I have in an old phone or even a 32gb SanDisk. Obviously I wouldn't want to make a 32gb card a permanent boot card, so that would just be temporary if I got it to work. Not sure how much more I can push myself to keep trying in hopes of just getting lucky.

Stupid mistake I made

Just thought I would throw this out there... I bought a Nook HD+ from Walmart a few days ago. Couldn't get it to boot from any SD cards. I followed the new procedure at the beginning. Then I realized... in Mini Partition Wizard, when I went to set the partition to 'Active' I never hit Apply. As soon as I did that, Bam, I was in. Maybe my dumb mistake can help someone else
[Nook HD, HD+ General] espylacopa:
I did the same thing initially and then when I fixed it, still no dice.
[Nook HD, HD+ General] john_i_:
After much frustration having tried at least 30 times with the boot images, I was finally able to create a bootable SD card on a 2GB card. I had originally tried a large card with the 4GB image, and the same 2GB card with the 1GB image.

What finally worked was for me to erase the partition table on the 2GB card, and manually create a partition of the correct size for the card.

I grabbed the	NookHDplus-bootable-CWM-6028-for-stock-BOOTFILES-r4-(05.15.13).rar file from this post to get the bootfiles:

http://xdaforums.com/showthread.php?p=35811322#post35811322

So, in linux, I did the following:

dd if=/dev/zero bs=1024 of=/dev/mmcblk0 count=10000
blockdev --flushbufs /dev/mmcblk0
fdisk /dev/mmcblk0

In fdisk, I did the following:
command (m for help): n

e extended

****** After fdisk, do the following to format the partition *****

partprobe /dev/mmcblk0

Now, copy the bootfiles from the rar:
cp bootfiles/* /mnt

Then copy the zip files needed for installing CM10.1

umount /mnt

I put int sdcard in the nook hd+, and it booted right up!

I hope this help others out there unable to boot from SD. Maybe the newer nook hd's expect the partition to match the card's geometry before they will boot.

My booting experience

Just wanted to relate my experience attempting to boot from SD to flash CM 10.1 and get my Nook+ 32GB off the ground. Nothing really new to add except that I booted at least 30 to 40 times without any success, removing and reinserting my SD between each iteration. I FINALLY got it to boot into CWM and was halfway through my baseline nandroid backup of the stock ROM when, to my profound dismay, the device powered off without warning. After shedding a few tears, I began the process anew, and after ANOTHER 30 or 40 boot attempts, literally one or two trys away from giving up and shipping it back for a replacement, it finally booted again. I didn't bother redoing the backup and just forged ahead with the factory data wipe and installation of CM/gapp zips. After reboot, everything worked perfectly. This was three weeks ago, and I'm still going strong, installing ROM updates and enjoying my tablet, with no major issues.

Just thought I'd reassure anyone out there who is about to give up. I can't promise, of course, that you'll succeed, but I can state that you may fail dozens of times and then suddenly win big.

The only SD I used was a brand new Amazon Basics 32GB, which I wiped after copying nandroid to my Mac and have been using in my Nook ever since with no issues.

Patience, grasshoppers.

[Nook HD, HD+ General] SEALBoy:
Got mine to work after about 4-5 tries. It worked when I left it off for a few minutes, and I held the nook button down as I powered the device on (not sure if that's actually supposed to do anything, but it worked for me). First thing I did was flash a native recovery so I never have to go through that ever again.

This was using a Sony 32GB UHS-1 microSD card.
[Nook HD, HD+ General] e.mote:
Well, just as soon as I said 'all 6 of my Nooks booted without trouble,' I should've known that Murphy would pay a visit and make me eat crow. The 7th Nook is the problem child that took 10+ tries to boot.

Tip to speed up the retry process:

When powering up from stock, the Nook logo will be at full brightness for about 3 secs, which basically acts as a splash screen. Then the logo dims as it continues with boot.

If Nook is to boot from SD card, the Cyanoboot logo will appear within 1-2 secs from power-up. If you see the Nook logo dims, then it's not booting from SD. Immediately press and hold the power button to power down, then remove/reinsert SD card to retry. This way, each power recycle takes 10 secs or less. If you wait until it boots up all the way, it'll take about half a minute for the whole cycle.

I tried to re-image the card with a different boot image (verygreen's 1GB one). There was no difference. The card was the same used for the first 6 Nooks. The only solution was simply to keep trying. I think it was 10-15 retries before it booted. By shortening the power recycle, it's still is a hassle, but short of an ordeal.

Good luck to all.

Just an update for me.... Turns out I'm just oblivious. I was trying to book using the NookHD files and not the NookHDplus files... Hana. When I had the right bootfiles on my SD card my Nook immediately booted to CWM. I felt like a moron once I realized my error. It wasn't until I went to unlock a Nook HD that I saw I had already downloaded the non HD+ files. That's when I put two and two together.

Has anyone else had an issue where the tablet wants to do a factory reset when you reboot it? sometimes when I go to reboot it to try and get the sd card to boot, it starts to do a factory reset.... I've tried all the different methods here for trying to get it to boot from sd and it's still not working. I ordered a different sd card to try, so hopefully that gets here soon :(

Same issue of not booting from SD

Well after 20 times of turning on and off it finally booted cmw all I did was push the n when it showed the adobe message screen.
[Nook HD, HD+ General] move_over:
Just to add another wrinkle, i just purchased mine on 8.10, and made a 2GB cwm sd card yesterday. Booted right away, but didn't see the zip files(root and extras). So I removed the card,rebooted, then turned it off. Reinserted the card, booted into cwm again, and second time around it saw the files. But it had some error doing a backup. So I flashed the files and rebooted again, had root and extras. Restored some apps with TB, then I had the idea to boot into cwm and use a 32gb card for a backup image. Again, it booted right away to cwm, made the backup no problem. Then, on reboot, it got into a loop and reset itself. Tried to use the backup image, but same thing-bootloop. I guess something I restored screwed up /system. So after entering all my information, and downloading apps again, and setting it up, I've made another (hopefully good) backup. I'm only going to flash extras this time, and see what happens. But I'm sure I restored an app that caused the bootloop.

At least it boots into cwm every time, with some no-name 2GB microsd I had laying around for who knows how long.

Don't know if it has any effect or not but I tried a lot of times booting and it only worked when I formatted the partition as FAT32. Sorry if it was already mentioned. Didn't see any post about it. I'm not sure if it must be FAT32, but it worked the first time. Before I was formatting only as FAT(16).

Booted in first try with the pushing SD Card and release when Nook logo appears.

I have the same problem here (newer nook hd+ with 2.1.1 firmware refusing to boot off disk w/ cwm). I've read through this entire thread and have partitioned 32gb class 4 patriot micro sd and set first partition as active with all appropriate files on disk but no luck. I have tried EVERYTHING (including newly discovered quirks such as push card/release during nook logo method and push N during nook boot method) and still no luck. Anyone with any insight on what the next steps might be is greatly appreciated.
[Nook HD, HD+ General] leapinlar:
The version of the stock (2.1.1) makes no difference. But the brand and class of the SD can make a difference. Patriots are not known for working well. Try a Sandisk. (And first partition is fat32, right?)
[Nook HD, HD+ General] chicodelta:
Both partitions are fat32. This has to be the most frustrating root process I've ever dealt with (no disrespect o mods, developers or anyone). I've rooted several devices but this process is sooo finicky. I read elsewhere to avoid class 10 cards, which I did, and now I learn that this could be a card manufacturer related issue? I appreciate the suggestion leapinlar so I guess I'll look for another micro sd and try this all over again.
[Nook HD, HD+ General] leapinlar:
Why do you have it partitioned with two partitions? That might also be contributing to the problem.

Just got my new unit hooked up by using a 16gb lexar class 10 card.

I tried multiple times and then finally tried the non burning method, extracted the rar file. tried few reboots. Here and there, it kept on asking to reset the tablet..

What is interesting is that it went on factory reset mode, I had almost given up on it so I just did the factory reset.

It booted into nook ROM, asked for basic setup info + registration data etc. Then it indicated that there was an update available and I noticed that it was picking up the file from the SD card. I said yes and it rebooted and 3 seconds later I was in cwm.

Hoping this helps someone figure it out.
[Nook HD, HD+ General] chicodelta:
In reading the instructions below I was lead to believe that the micro sd should be set to two partitions (i.e. first and other)

Quote:

Format any size card with SDFormatter (free on web).

Use partitioning software (Mini-Tool Partition Wizard or EaseUS Partition Manager, both free) to set the first partition as "active".

Unarchive the appropriate set of BOOTFILES for your device (HD or HD+) from my .rar file attached below and copy them to the SD. There should be five files.

Move on to item b below to copy the installation zips.

Anyhow, to make things even more interesting now, my nook went through a few factory resets and it is now back to firmware 2.0.6. I don't know if this is typical/common or a fluke. I tried rebooting again with my current card but no luck. I ordered a second micro sd and will try again w/ the non-patriot card to see if I have better luck.
