[Q] CM9 wifi fix and reading SD card in general - Nook Color General

I hate to post but I have been searching through this forum and the net for a few days and cannot find the answer.
I have a NC that I have been running CM7 on for about 5 months ( thank you to everyone who has worked on these programs ). But I saw that CM9 came out and wanted to play.
I installed CM9 and gapps and my NC is working fine except it has no internet. So I saw that there was a fix to change a file using a text editor and that is where I run into problems.
I am running Windows 7 and when I hook up the SD card all I see are 4 files and I cannot see the other folders etc.. I even installed Ubuntu and that showed the SD card as 3 different devices.
So All I need is to find out what progam I need to read the SD card. So that I can configure my internet correctly and add my books and movies onto the SD card.
Thanks for any help on this.

You should not need any fix to connect to the internet wirelessly from CM9 on your nook. There may have been a solution a long, long, long time ago, but out of the box it should be fine now.
What happens when you connect to Wifi? Click on your wifi network after it shows "Connected" and see if it shows an IP address. If so, post it. It should be something like 192.168.x.x

Are you running CM9 on an SD? And are you taking the SD out and putting it in the PC? That what it sounds like with your description.
If you are, the system is acting properly. On an SD install, the SD is partitioned onto four partitions and when you remove the SD and put it in the PC, only partition one can be seen by the PC. That is the boot partition, which normally has only four files in it.
That being said, you do not edit system files that way. You use a root file manager like Root Explorer to do it on the nook itself. I think that file you were talking about was under /system somewhere. (Wifi adhoc or something?)
But I also agree with the last poster that said wifi should work without having to edit system files.

Yes I am running CM9 on a SD card. So what you are telling me is that with the SD card physically in the nook I should have no problem seeing the folders etc. when ii is hooked to my computer by a USB cable. Thanks.
As far as the internet problem I am still having it. I " forget " all the wireless and then hook up to mine and put in the password and it tries to connect but then comes up with " Authentication problem " and cannot hook up. I am running WPA2 and had no problem connecting in CM7.
This is what I found on the net and the date of the post is 5/11/12
"1.Power off your Nook Color
2.Remove the SD card and put it into your computer
3.Navigate to the partition on SD card that contains the “etc” folder
4.Go into “etc/wifi/”
5.Open “tiwan.ini” using any text editor as administrator
6.Find “WifiAdhoc = 1″ and change it to “WifiAdhoc = 0″
7.Save the file and close it (check to be sure your changes saved)
8.Put the SD card back into your Nook and turn it on
9.You can now connect to WPA and WPA2 secured networks"
This is why I was trying to read the folders on the SD card with it plugged into my computer.
is there sometimes a problem using WPA2?
I am using the " generic sd card v1.3 ICS large img.zip " and the nightly I used is " cm-9-encore 20120708-800 open gl " the gapps I am using is " gapps-ics-20120317-signed.zip"
One thing I did notice is my NC is listed as a " mobile device " when I hook up to the computer and not as another HD.

No, you do not edit that file with your PC. Whoever posted that stuff was all wrong. You cannot 'navigate to a partition' using a PC (maybe you can with Linux, but not Windows.) You edit it with your nook while it is still in the nook using a root file manager like Root Explorer.
And that 'mobile device' you see is the new protocol that cm9 uses called MTP. It is not a drive letter, but you are still seeing your 'sdcard' and 'emmc'.

[Q] Problems with SD cards / running Honeycomb

Hey guys, I think this should be a pretty simple question to answer but I can't find anything specific when I search google. I've been having trouble running different builds of Honeycomb on my nookColor: v2, 2a, and honeybunches all would not let me connect to wifi. Everytime it would go to connect, the signal would drop to zero and nothing would happen. Any thoughts on this?
Also, since I only have 2 microSD cards I would use Easeus to delete the partitions on the disks and then use SD formatter to reformat the cards so I could install a new build of Honeycomb to check the wireless. However, the capacity of my 8GB card has gone from ~7.6-7.8GB to 7.46GB when i am trying to format it for the next time. Easeus shows a 7.647GB unallocated partition, but the formatter wants to format it to 7.46GB. I don't understand why it has gone down, and it makes me worry that I unwittingly lost space on my SD card. Have I screwed up my cards, or can I get this mystery space back? Please help!
Remove SD card from Nook and boot into stock. Insert SD card, go to settings, Device Info, SD card, unmount sd card, then format sd card. This will/should delete all partitions, format and restore all usable space on the sd card. From here, download and burn the honeycomb image to your sd card. (I recommend ubuntu, dd command. Open terminal, navigate to the directory that contains your nookhoney image. Once there type; "sudo dd if=nookhoney02.img of=/dev/mmcblk0 bs=1M" without the quotes. Note that nookhoney02.img could be nookhoney02a.img or the honeybunches image depending on which you are using and mmcblk0 could be mmcblk1 etc. depending on what the name of your sdcard drive is.) After the image is done writing, power Nook down, insert sd card and boot Nook. Also, the burning process can be done from windows using winimage and what not, the whole ubuntu thing was just my recommendation. Hope this works for you, any more questions, just feel free to ask. Also, I apologize if this is repeat information, just giving the full experience.
just use dd command in linux or osx will erase all the partition, don't need format or erase the card first.if you do so the sd size will not decrease.

Have you tried turning WiFi off and then on again? This seems to work for me when wifi is acting weird.
by turn off, do you just mean press the wifi button in "Wireless & Networks" or the enable disable buttons in the dev tools? i've tried the first solution to no avail. I guess I could try messing around with the dev tools.
The nook doesnt have to be rooted for me to run this off my SD card right?
EDIT: I just went over to B&N to check if their wifi works. It does, so i don't know what the issue is. Possibly because my university uses 802.1x EAP for their network? The only thing that is fishy is that my nook at stock would connect fine.

Answer to your first question yes turning off and back on in Settings>Wireless.
I know I had mine working on my uni's network which has 802.1x but can't remember if it was stock, Froyo, or HC. Not currently on campus so I can't try it for you.
Google "SD formatter" and download the application. It's free and very easy to use and will format your SD cards.

That's what I was using, but the size seems to keep getting smaller and smaller. I'm losing about .01GB per format.
EDIT: Okay now the wifi is working in the dorms, and i hate to say this, because it's so humiliating, but I think i was using the wrong password to log into my wireless network. Which is probably why it hung on connecting. Which makes me feel dumb.

Well at least the wifi is working for you.

How do I put files onto my sd card that has been made bootable?

I have installed bootable cm7 on my 8gb sd card. It only shows the first partition when I connect it to my computer. I tried connecting my nook color to my computer in both cm7 and stock firmware, but the card isn't readable in either case. In fact when I connected using cm7 it didn't connect at all.
I am trying to put some pictures onto the sd card, but can only get them on the first partition, is there a way to get them on the larger partition?
Enable USB mass storage for the use since it's the only way.
Boot CM7 up, connect NC to PC, look at the NC's notification area, usb icon should be displayed, tap to open then enable USB mass storage.

There is a program developed here on XDA that can mount your micro SD installed CM7 media data partition that you see on your NC but normally can't see when connected to your PC. Normally the pc sees the first partition only (boot). This program will let you also mount your 4th partition on the sd card so that you can add your media files there. Install the program, tell it to mount your 4th partition, and connect your usb cable to the pc. It will show up as a drive letter. You can download the program here:
http://forum.xda-developers.com/showthread.php?p=11322639
This is also very useful for those users with ics preview on their micro SD card.
The app had been integrated into CM7 builds so long time ago, no need to install it separately.

I used it on the new ics preview build. It's the first time I had used an SD install, and the usb mount is broken so far so this little app was great.

I am running nightly from 20121227 on a sd card(2GB) on my nook color. Everything is fine except that when I connect it to my pc, I see the nook as MTP device on my pc. I see the SD card with a storage of 180MB only. the nook internal card shows up as full. I do not see the usb in the notification area of the nook. I want to be able to add music/documents to my sd card so I can access them from my nook(when I boot it from sd card).
Thanks

Go to Settings-Storage select 3 dot menu in upper right corner and select Mass Storage. You will then be able to see the nook USB notification.
The nook will show up as a drive on your computer. Use Clockwork Mod Recovery to partition SD card to reclaim space, but with 2gb not much remains for user media (cm10~700mb, ram~512mb, etc).

Tried that. Now when I connect to my PC, I see only one FAT32 partition(boot) and it shows only 180MB size. I do not see any other partition. Do I need to use a larger size card (>2GB) to see the additional partitions.

Take a look at this thread http://forum.xda-developers.com/showthread.php?t=1585572&nocache=1
You may need a higher capacity card if you plan on adding lots of music, books, comics or movies.

See my post above with the link. In cm7 there is a setting to use emmc as sd.
For easy access use a wifi connecting app like WiFi File Explorer Pro; see whole card, quick UL & DL of files.
You can also use debugging over network settings in the ROM and use adb...
The first time you do it do this in a command or terminal window:
adb shell busybox mkdir /sdcard/boot
Then every time you use it to transfer files to the boot partition for flashing:
adb shell busybox mount /dev/block/mmcblk1p1 /sdcard/boot
adb push ROMFILENAME /sdcard/boot/DESIREDROMFILENAMEONDEVICE
If you are wanting to transfer files to the "sdcard" partition of the card:
adb push FILE(s) /sdcard/DESTINATIONFOLDER/

Followed those instructions. Still I see only the main partition in windows explorer. Under disk management I see 4 partitions. In my tablet, I see the 180MB partition. Also I see another with .93GB showing up as internal storage. The emmc shows up as another internal storage. Not sure how to get files into it. I am attaching screen shots.
You are only going to see "Windows"file systems (partitions) in Explorer (FAT, NTFS, etc). The other partitions are Linux type partitions (ext, etc...).. Explorer won't see them. Thus the need for ADB.
Personally I sometimes find it easier to place files in Dropbox and then just deal with them on the device rather than through the cable. You will need the Dropbox app on your NC.. available in Play store.
Since CM ROMs have debugging over network support... there's no need for the cable when adb'ing into the device.

nook dual usd card files tranfer from comuputer

Hi
Please respond to the following. I tried a lot to look the answer to my problem in the forums, but could not find it (or did not get the right forum)
I dual booted my NC with CM7.1.0. It was working fine without any problem, but suddenly stopped entering into the main screen. Whenever i on the nook the Cyanogen loading ... screen comes and then screen flashes and turns lit black.. the NC is not off but it does not reach to the main system. I tried to use update the CM by copying a new file to usd, but it did not let me do so.. computer hanged. I do not want to format it as it has some .xls files in documents folder in the 4th partition of usd. Can someone please tell me how to extract those files using computer's sd car slot ( I can not use nook usb option as it is not booting CM) and how to recover the older working condition.
I assume you have stock working on emmc. I have a flash file that you can temporarily flash to stock to make it read the fourth partition of the SD as 'sdcard'. Go to my tips thread linked in my signature and item B3 in the second post (last paragraph). It tells you how to modify stock to read that partition. If your stock is rooted, you can just edit the file yourself. If not rooted, you need to flash one of the files attached to the post. Instructions are there. After retrieving your files you can revert stock back to normal by re-editing the file or by flashing a second zip, or just keep it that way and use partition four for both systems. Then you can start over with your verygreen SD and reinstall CM7.
could not get it

Thanks for being so patient. I dont think it is rooted and the stock nook is touched as i follow a link provided in this forum to boot usd and dual boot nook without losing warranty to install cm7 on a usd.
When i use boot the nc, i see following responses
1. boot without usd: boots to original nc, all files and applications are there and work perfectly fine.
2. boot with usd without going to boot menu: cyanogen loading banner shows up and then screen flashes. .then a lit black screen .. nothing happens after that
3. boot with usd and selecting emmc in boot menu: boots to original nc but hangs at home screen
4. boot with usd and selecting sd (external storage) in boot menu: cyanogen loading banner shows up and then screen flashes. .then a lit black screen .. nothing happens after that

Your SD is definitely messed up. You will need to reinstall after we get your file saved that you want.
You will need a spare SD card that you can put my bootable CWM recovery on.
Go to my tips thread linked in my signature and download to your PC three files attached there. The one that starts CWM... and the two that start update-stock...
Extract the CWM zip. It will have a 200Mb .img file in it. Burn that to the spare SD just like you did when you made the verygreen SD. Once that is burned and you can see it on your PC, copy the two update-stock... zips to it.
Remove that SD from the PC and put in the nook. Boot. The CWM menu will come up. Select 'install zip from sdcard '. Then select 'choose zip from sdcard'. Scroll through the list and pick 'update-stockemmc-vold-fstab-modified-for-partition4.zip'. Then confirm the selection. It will flash the zip. Remove the CWM card and reboot to stock.
Insert the verygreen SD and you should be able to connect your USB and see partition 4 on the PC as 'sdcard'.
To return your stock to original after retrieving your file, just go through the process of flashing the other update file with CWM. But most people like leaving it modified so that they can always use just one SD for both systems.

I did exactly same, but could not see partition 4 on the pc as 'sdcard'. I see two drives 1. mynookcolor ( i can access all files in it), and 2. a removable disk drive I:/ ( that i can not access). I do not see my files (see pic below) those are on the 4th partition of sd card.
You need to mount the card in settings. Go to settings, device info, SD card. And choose 'mount SD card'.

It is already mounted. It shows sd card memory (not available), unmount SD card (\unmount the sd card for safe removal), and format sd card (format (erase) the sd card). However, only third option is active others are grey/inactive.

If it says unavailable and the first two are greyed out, that means it is not mounted. Pull it out and put it back in... wait you had the cable unplugged when you checked that didn't you? You should have.

What I am asking is with the USB cable removed, what does the settings show? If you remove and replace the SD with the settings window open, is there any difference? You say it detects it, how do you know that?
Edit: I have been searching for a solution for you. There are two ways to see those files with your PC. To view it in Windows, you must make several complicated changes to your drivers. I'm sure you do not want to do that. The other way is to use Linux. It has the ability to see and mount multiple partitions on an SD. You can either find someone who has a Linux system to do it for you or you can make yourself a Ubuntu Live CD that you can boot with your PC. None of these options are easy, which is why I was trying to do it the other way on your nook.
I don't know why your system is not mounting that SD properly. Even if those changes I had you make were not there, it should at least mount partition one on the nook.

The card is not written correctly... if you format it in the nook... you will see it on your computer... then you can remove it... and try writing the uSDcard image again with win32diskimager

Dizz, he was trying to figure out how to get his data off of partition 4 before he reformats and starts again. I was hoping he could do it with the nook, but it is not reading it. I had him modify emmc so it can see partition 4, but no luck here. Do you have any ideas?
Sent from my Nook Color running ParanoidAndroid and Tapatalk
I just had another thought. Put the card in the PC and open with your partition software. Delete partition one, two and three. Then maybe windows can see partition 4, since it is now partition one. You may have to move it to the beginning of the SD, but I don't think you have to.
Edit: I was able to test this on my spare SD card with the EaseUS partition program and it works. Be sure to give it a drive letter.

No, your installed apps are stored on partition 3. But if you bought them, google lets you redownload and install to as many devices as you want, as long as you are logged in to your Google Play account. What you will get back is things you had stored on 'sdcard' (pictures, books, music and other files like your xls files you wanted, what you saw in that screenshot you posted.)

I had thought of this before I commented about the SD being not formatted correctly... should only have to delete partition 1 ("boot") since windows should use the first fat partition....
However...
Since the nook doesn't show "unmount" or ""sd card memory" active... it is certainly not reading partition 1 correctly.
He can flash my B&N 1.4.1 with SASD vold.fstab edits to see partition 4 (if it can read it) and transfer everything from that partition.

[Q] SD Card Error

I searched the forums but could'nt find a similar problem. My SD card is read by my phone. But when i connect it to the computer through USB storage, only a few folders are seen(lost.dir, buildprop.tmp, .profig.os) along with any new folders that i create. But while browsing the card through a file explorer on my phone i can see all the files and folders. Anyone know what's wrong??
Try to put it in a card reader and see what happends.
Hey
I bought a sd card from eBay and had countless errors and trouble with it, I bought a new sd and had no issue what so ever. So try a new sd card or even formatt the memory card

See if you can back the contents up to the pc then run disk check or format.
Formatting at the moment is not an option. I have a lot of data on it that needs to be backed up like photos, videos, music etc. Unfortunately i cant backup the contents onto the PC since they cant be seen! Guess i have to upload everything onto dropbox and then format it. And with my current upload speed its going to take days . Unless there's someother way of doing it
Try doing a backup using a card reader for your pc.
Even with a card Reader only the "New" folders that i create can be seen. But on the phone All the folders can be seen.
Have you tried to connect it with Linux based OS or only with Windows?
Try this also. Currently there's a troyan round the globe. When it activates it hides all the folders on external media devices connected to PC, and creates .exe files with names of hidden folders. When you connect your storage to a PC with good antivirus it deletes .exe files but leaves folders on storage in hidden state. Try to configure your Windows Explorer or Total Commander to show hidden files and folders and maybe you'll be lucky.
Only with Windows XP and 7 based systems as im at a cousin's place. Found this problem when he wanted some songs from my card. I did scan the SD card using AVG. During the scan i noticed that the current files being scanned included those that i couldn't see using windows/commander file explorer. Hope that helps
Edit: A little messing around and i got it!! Folder Options > Hidden Files and Folders > Unchecked "Hide Protected Operating System Files"
Thank you for all your help

Kindle Fire running CM 12, doesn't detect external sd card

Hello,
I'm running Cm 12 (based on this xda thread. I did my original install off of this RootJunky tutorial.
I'm not getting access to the external sd card. I have wiped and re-flashed about 6 times in TWRP, each time pulling my flash files off of the external sd card, I have tested the card in a pc, works fine. But it's not showing when I run the tablet or when I connect the tablet to my laptop with a usb cable.
Any ideas or suggestions on how I can fix this?
Thank in advance for any help!

Cm12 currently only works with certain file systems, do you know which file system the SD card is formatted to?

I just finally solved it, and I hope this thread can help some other people -- thanks for the response, by the way! I have been reading some of your other posts this week, and you are the man!
So, what I ended up doing was backing up my sd card on a pc, then reformatting it. It still didn't work. But CM 12 was giving me a message every time I took the sd card out of the slot, telling to insert a card. I was exploring permission in SuperSu and CM 12, and eventually I ended up activating the "Delete Sd Card" option under storage. I didn't think it was available to me, because it was grayed out and didn't show my card anywhere. It was. I deleted it, and it must have reformatted it with a compatible file system. It works. It's letting move apps to sd card, sd card shows up in file managers, other apps and when I connect to pc.
Now, the only issue I really want to resolve is getting Google Play Games to work.
