There are two different scenarios.

1. Running the ROM from the SDHC? Not installing on the NC. If so you will need a ROM that is packaged with this in mind. There are some on XDA and you would not be using them with this SDHC image as it stands.

2. Most ROMs are build for CWM installation on the NC, however these may install properly with this SDHC image.

I used a ROM (MIUI 1.9.23 a CM7 based ROM) .zip file intended for CWM installation with this SDHC image and it worked fine for me.

Hope this helps
[Nook Color Android Development] Aerlock:
There's an update zip at the bottom of the original post (See link below) to update you to the 1.3 version of the installer. I would install that first and then do the 7.1/nightly .zip.

Not exactly, If he were using CWM then yes these would apply. He would also need a version of CWM that works on SD cards. The Size-agnostic SD Card image and CM7 installer for SD Cards that he's using adjusts the normal CM7 Rom for the Nook Color to the CD card and puts everything in the correct place to run off the SD card.

[Nook Color Android Development] sark666:
Thanks, I didn't notice there was a file to upgrade to 1.3. However it says you can put that and an update-cm file providing there's 1 meg free which I didn't have.

So I copied only the update-genimage-1.3 and booted into recovery. After that was done I shut off the nook and put the sd card back into windows and it's mounting as read only. I tried the same on a linux box.

I don't think this unmounted correctly. With the sdcard in it no longer successfully boots to cm7. I tried cycling recovery again and it ran through recovery and auto-shut off. I had hoped that unmounted it correctly but it's still read-only on win/linux.

Edit: for whatever reason stock would mount the sd card as read/write. I copied over cm 7.1 and it installed fine.
[Nook Color Android Development] lschroeder:
I have been having a lot of trouble with emmc and ClockworksMod Recovery hanging when trying to format system, so I thought I go back to the size-agnostic approach I used in the past.

I put in a SanDisk Class 4 Card. Wrote the generic-sdcard.img from generic-sdcard-v1.3.img.gz. using Win32DiskImager. Used EASEUS Partition Master 7.0.1 Home Edition to expand the image to the full size of the SanDisk Card. Copied over update-cm-7.1.0-encore-signed.zip and gapps-gb-20110828-signed.zip.

Safely removed from my pc. It booted with a Loading message and the Penguin showed it installing stuff. Rebooted, got green cyanogen image followed by black power screen. Force quit using power+n.

Removed from nook and place back in pc. Unlike in the past where it showed a boot partition of 115mb, the SDcard still showed full size. However the update-cm-7.1.0-encore-signed.zip and gapps-gb-20110828-signed.zip were gone.

The partitions did not get written. Tried again only copying cm-7.1.0-encore-signed.zip this time. Had to use green cyanogen image boot loader by pressing "n" key after startup to set boot to sdCard and recovery. Again Penguin showed activity but same results as before. I tried to read the partition info as it went by but it was too fast.

What should I do next? I have tried to restore to stock. It appears to me that system/partition formatting is causing problems everywhere. Time for adb? What are the commands and files I need to use adb to repartition the nook?
[Nook Color Android Development] DizzyDen:
Larry, what I suggest is to redo... note what I made red above.... you cannot resize to entire uSD size before booting it in the nook first... you then are leaving no room for the other 3 partitions.

Write SASD 1.3 img to uSD... resize the only partition on it to 2 GB... put your CM7 image.... put it in nook and boot it up.... it will create all its partitions and install CM7.... I would then:

adb shell busybox mkdir /sdcard/boot

adb shell busybox mount /dev/mmcblk1p1 /sdcard/boot

adb shell busybox cp /sdcard/boot/uRecRam /sdcard/boot/uAltRam

adb shell busybox cp /sdcard/boot/uRecImg /sdcard/boot/uRecImg

adb push (GAPPS) /sdcard/boot

That will put gApps onto the boot partition and you can boot recovery to install it.

That will also copy the original recovery files to alt boot files so you can do updates by just booting with vol +/- pressed in the future.

for future updates all you have to do is:

adb shell busybox mount /dev/block/mmcblk1p1 /sdcard/boot

adb shell (UPDATE FILE) /sdcard/boot

and reboot the device holding in vol +/- keys.

no video

I recently took the plunge and re did my SD CM7 from nightly 30 something.....

I used Win32Diskimager to put 1.3 on the disk, and then put the nightly 226 build on the root in windows.

The install went fine, and after words I put on gapps from the bottom from the linked page.

Everything is fine so far.

I got on market and picked a few apps and here is when I noticed the problem. EVERY website with a video or Youtube or Netflix all bomb out on loading the video saying there was a problem with playback.

I am also getting a DSPManager failure warning on each boot up,and I am guessing they are related.

Do I need to just start over?

Thanks

generic card image

I am putting updates and image onto my card and here is where the problem is for me... The image file that is stated in the original post is on the end says image.gz and when I go to winImage it doesn't recognize it because it isn't a .image Is it something that I am doing or a problem with the file?

Thanks!

Crissynak
[Nook Color Android Development] DizzyDen:
did you extract the .gz file to get the .img file inside? Also, if you run into issues using winimage after extracting the image... you may want to use win32diskimager. This has caused several problems in the past.
[Nook Color Android Development] Crissynak:
I just clicked the link that was on the original post and then seeing if i can extract the file it doesn't give me the option to extract. This is the file name generic-sdcard-v1.3.img.gz Still no recognizing it. Is there another way to get the correct file?

---------- Post added at 11:43 AM ---------- Previous post was at 11:33 AM ----------

I also noticed that it isn't downloading as a zip file the icon looks like a sheet of paper and not a folder with a zipper. Could this be the problem? When I do find the file it just gives errors in both imagers that there was an error reading the file.
[Nook Color Android Development] DizzyDen:
if you use 7zip or winrar they should both be able to extract .gz files... personally as much as I like 7zip, I find winrar better at that than 7zip.

You can also find a program called win-gz (or windows gzip) to extract .gz files.

Inside the .gz file will be the img file.

Update...

So I did a search on the .gz file and I found out that the way for me to extract it was to get a program called bit zipper. So then I opened it through WinImage and when I went to write it on my sd card it said that "it wasn't empty and will lose everything on the card and that the image format is not supported for the card and will be resized", is this ok? :confused:
[Nook Color Android Development] dcharleyultra:
What brand and size card are you using.

Swyped from my Evo 4G using Tapatalk
[Nook Color Android Development] DizzyDen:
No, you do not want to do that... WinImage will resize the image to fill the SD... you do not want that since it will leave no room for the installer to set up the partitions....

Use Win32DiskImager...EVERYTHING on the card will be gone... it will write the img to the card as one 113(ish) mb partition... you can then put CM7 on that partition (it will be named boot) and put it in the nook... it will set up the other partitions on your SD and install CM7 to run from it.
[Nook Color Android Development] Crissynak:
Ok so just for reference I have a Kingston 8g hc microsd don't know if that makes a difference but here is the next issue. So i went to write the image onto the sd card and now it just keeps telling me that there isn't enough space on the disk. I also have a 2g sd card but not sure what brand it is since it doesn't say it on the card. I will try that one also to see if that might do something.
[Nook Color Android Development] Crissynak:
UPDATE:

Ok so I tried using the 2g card and still the same thing, not enough space on disk. I formatted to make sure there was nothing on the card also.

I was reading the original post and read this:

*Partition layout for the SD cards depends on size:

2G cards (more than 1G up to 1800M) gets: 300M system, 612M data, rest is FAT sdcard*

Is this automatic or do we need to adjust this as listed because my computer doesn't show all this info when I go to format or anything like that?

Anyways should I just try a new sd card?
[Nook Color Android Development] DizzyDen:
The partition layout is automatic... that is how the install script sets it up when you run it in the nook the first time.

You can write the image to the card... I suggest Win32Disk Imager to do that... then use MiniTools or EASUS Partition Manager to increase the size of the boot partition (or just verify it)... I like to resize the boot partition (I use 2GB since when you boot to EMMC installed ROM, it sees this partition as well). There's also a few SD formatters... I found SD Formatter by Panasonic to work.. but you have to make sure you change the options to resize if you want to make sure the format completely reclaims SD space.

There has been reports of people ignoring that error and it working anyway... but I have not had issues with the image writer I mentioned above.

If you need more help... you can pm me... I can give you my phone to help in real time.
[Nook Color Android Development] Rattor:
I tried searching, but I'm having an issue where no matter what I search, it comes back as saying "No results found", so forgive me if this has been asked recently. How would I go about upgrading an install of CM on an SD card that's 8gb to an SD card that's 16gb, without having to redo my settings and such? Is there a way to simply copy it all over?
[Nook Color Android Development] DizzyDen:
disk32imager... read the sd card to a file (make sure you select folder and provide name before read)... change SD cards in your reader... write that image.

EASUS or MiniTools Partition manager to increase 4th partiion to use remainder of SD.
[Nook Color Android Development] Rattor:
I currently have update-cm-7.1.0-RC1-encore-signed installed on my NC (from before 7.1 was officially released). Would I gain anything by upgrading to update-cm-7.1.0-encore-signed, or are they the same? Are there any changes between the 2 releases?
[Nook Color Android Development] DizzyDen:
There are MANY changes between the two... you're looking at 3 1/2 months of updated code between the two... I knew I should have been logging changes all along.
[Nook Color Android Development] Rattor:
How would I update? Can I just drop in the new update.zip file into the boot partition and boot into recovery, or do I have to backup, wipe, and reinstall?

EDIT: Also, do you have a link to the list of changes between the two? TIA.
[Nook Color Android Development] Aerlock:

[Nook Color Android Development] DizzyDen:
The first thread you list is for MN'd stock... does not apply to CM7...

If you could provide information as to which files you used from this OP and what uSD card you are using it may help.

If you are using any CM7 after N95 (if memory serves correctly) you MUST use the SASD 1.3 due to kernel update... if you used 1.1 or 1.2... that is most likely your issue.

If you are using a class 10 uSD... that is most likely your issue.

There are several possible issues... and different solutions.

Personally... anytime I create a new SASD... I install CM7 alone first... set up my wifi... then install gapps.
[Nook Color Android Development] GuTsaV:
I actually have a 32GB class 10 uSD from AData. It worked great with nightlies around 176-200. I used 1.3 all the time.

But when I updated to 7.1.0 with the stable update, it started to get stuck in a boot loop sometimes. It would most often work if I hard rebooted.

I thought wiping the card and put the latest nightly (237) on it would solve the problem, but ever since it always got stuck in a boot loop. I tried installing older versions too. They install without problems, but won't boot.

A class 4 Sandisk 8GB uSD is on it's way to me. Is it more likely to work?
[Nook Color Android Development] dcharleyultra:
Yes, that uSD is more likely to work.

Recently moved from 7.1RC to 7.1 stable on my SD card.

Before updating I reloaded a backup copy of from when I first started using 7.1RC as I was hoping the SOD problem which I never had when first loaded would disappear and as I had not put any new apps or updated many since then.

Everything went smooth SOD problem still exists however but I work around it by turning wifi of before powering off or just letting it self power down.

The thing I find curious though is that my older version that I updated had the original marketplace gapps. This had been automatically updated and was always a problem, fixed by going LCD 160 and clearing but even then was always slow compared to the original market. I now find that the original has been on my NC with CM 7.1 stable for about 2 weeks and no update has occurred keeping my fingers crossed as I prefer the old version, faster loading and easier on the eyes to me.

I seem to recall a thread that said eventually this gapps version would not work, Is that true?

How do I do a Nandroid backup with using using CM7 on SD card? I tried booting into recovery from ROM Manager, it goes the the penguin screen but then shutdowns after a bunch of text displays. Part of the text says something along the lines of "It appears SD card already properly partitioned" then "All stages complete", then "Preparing to shutdown".

How do I get to CWR to do a Nandroid backup?
[Nook Color Android Development] bluepen61:
Not quite sure what CWR is but here is a method:

I created a bootable CWM card following this.

Then booting to CWM, used its Backup/Restore facility to backup my NookColor. Btw, it is CWM version 3.0.2.8. It copies the emmc to the CWM uSD card.

Now, as for backing up CM7 when running CM7 from uSD card... Hmmm... try hooking up the NC to a PC with a usb and backup to the PC. A second method might be to copy the uSD card that has CM7. But by definition, an Nandroid backup refers to backing up the emmc portion, not the uSD card, is it not?

To backup CM7 on a uSD just power of the nook, put the uSD in a USB card reader and image the entire uSD card on a computer (I use winimage) that saves EVERYTHING, verygreen's boot loader, apps, data, all in one shot.
[Nook Color Android Development] saber0091:
Alright, got everything to work. Made a backup image of the card on the PC so I can mess with partition sizes and not beef it.

I ran through EASEUS Partition Manager, trying to increase the Boot partition size. When the dust settled, it looked perfect on the screen, but then I put it in the Nook and the EMMC stock Nook wouldn't recognize the SD card, and booting to the SD card... Cyanogen logo came up, then it hangs on blank screen before the boot animation has a chance to come up.

So... what's the right way of going about resizing?
[Nook Color Android Development] DizzyDen:
You have to resize the boot partition BEFORE you put it in the nook... once the ext partitions are created, windows can't resize it properly.... so... write image... resize boot to what you want (don't exceed 2 GB)... put cm7 on it and boot it in nook... resize 4th partition if necessary.

I had an odd problem today on my Nook Color (CM7 on SD card). Suddenly the Google+ app quit working. Admittedly it had been a long time since I'd used it on the Nook. Thinking it was logged into the wrong account (since before Google enabled G+ for my Hosted Apps domain), I cleared data and tried to log in with. I got an error (something about the server). I went into manage applications and cleared the data for Google+. No progress. So I uninstalled Google+. That was a bad move.

At that point the web Market said that Google+ was not compatible with my Nook Color.

I uninstalled updates for the Market on my Nook. Then quickly went into it and downloaded Google+.

That worked fine and I got logged in. As soon as I went back into the Market on my Nook it had updated. And now the web Market says that Google+ is not compatible with my Nook Color.

I'm afraid the problem is going to come back.

I feel like such a noob.

I used Win32DiskImager.exe and backed up my uSD then restored it to another uSD card.

I downloaded update-cm-7.1.0-encore-signed.zip and put it in boot on the new card. I've actually used this card before so it's good.

Then I booted up normally. Then I pressed the power button and chose Reboot and then Recovery.

I get the recovery process but it doesn't update.

Here's what I get.

When it finished the Nook shuts down. When I reboot, it's still on the old ROM and the update-cm-7.1.0-encore-signed.zip is gone.

What am I doing wrong?
