Titanium Backup (paid version) can clear dalvik. There are also a number of cache cleaning apps in the Market.

How many networks did it previously show?

Maybe it's as simple as turning WiFi off and then on again? Also making sure that Airplane mode isn't enabled.

[Q] Can I use UOT (for CM7) to get a circle battery ?

What do I need to upload to them?

(which files)

running the uSD card dual boot setup.
[Nook Color Android Development] smarcin:
Thanks for the idea for usingTi. I had tried to wipe from recovery. I was able to wipe cache, but not dalvik. I expect the path was different from what was expected.

I did find one suggestion which I can't credit, as I'm posting from my nook. It was to download and run Wifi Analyzer. Since I couldn't get online from MiRaGe, I booted into ICS and downloaded it. Then I backed it up to my uSD card. I booted into MiRaGe and installed from the backup. When I ran it, it said I wasn't connected, which I wasn't. But I was then able to turn wifi back on, see all the networks around me, and connect to my Evo 3D. I had already tried toggling wifi and airplane mode.

Racks, if you're reading this, could you please list the partitions, their sizes and the file system types that i should be seeing? And Les, could you please list the steps you used to enlarge the data partitions? TIA.

I'm still having wifi problems from time to time. I can turn it on but it won't see any networks around me. If I turn wifi on my Evo 3D, I can see them, though. If I do mess around in Wifi Analyzer, it seems to help. I had also tried forgetting networks, but that does nothing for me...

[Q] CWMR not backing up either system or data?

I'm unsure how the disk (microusb) is partitioned?

from CWMR dump & mount

tempfs:

uSD:
(CM7) .android_secure.vfat.tar
p1 [primary] Fat32 /boot boot.vfat.tar
p2 [primary] ext4 /system (CM7) .
p3 [primary] ext4 /data (CM7)
p4 [container] ------- ------------------- --------------------------
p5 [logical] ext4 /system (CM9)
p6 [logical] ext4 /data (CM9)
p7 [logical] Fat32 /sdcard (7&9) --------------------------

emmc:

/dev/block/mmcblk0p7 ext4 /cache (7&9)

Is here a known problem with this customized CWMR for uSD

for CM7/9 ? I have about 16gb free for backup data.

Thanks

works than breaks after Gappsb

I ddownloaded and installed the dualboot to my sd card... booted in to both roms and turned on Wifi. Booted into roms again and all worked well. I then installed Gapps from the zips on the card. Booted into each rom and used the market. Then the next time I went into cm7 i started getting force closes on adw launcher and some other apps. This happened with adw often enough to get it reappearing right awayafter pressing force close. I reinstalled and rewrote the sd card, keeps happening for me after Gapps it seems any ideas?

Also I saw a post somewhere about some changes with the newer nc ... they have serial numbers starting with 2012, 2013, and 2014. That this may cause some problems with roms and things, mine starts with 2012

Hope someone has some ideas.... I really want to run cm7

Another question for Racks:

Have you thought of making it so we can install any zip for any ROM? Kind of like Boot Manager for many HTC phones, though that is an app. I'd like to be able to put Miui on my SD, too.
[Nook Color Android Development] davidbudd1:
Great work. Looking forward to updates as they come.
[Nook Color Android Development] racks11479:
Yeah, just tried it myself and same issue. I've taken a look at the code. And when building recovery for the dualbootsd I forgot to edit some additional lines so it backs up /system1 and /system2. Right now it's looking for /system. And that mountpoint doesnt exist for the dualboot recovery. I'll look into updating that when I have a chance.

I don't know of the issue firsthand. I don't have a device that starts with the serial stated above. Does anyone else with the starting serials above have the same issue?

I'm working on getting verygreens installer to do just that for my dualbootsd. The only thing with that is, with the CWM recovery included. You can format and backup partitions. With verygreens installer it does everything on the fly without user input. So its a give and take.

Gonna try and build with Fattire's updated info to include the new drivers tonight.

Thanks,

Racks
[Nook Color Android Development] webdroidmt:
Hey Racks, sorry for going a bit OT here but are you still considering getting a NT? From fattire's post last night, looks like they are really starting to come along with it.

I'm thinking I'll give my NC to my daughter-in-law, let her run CM7 Mirage for now and hook her up with CM9 down the road. As for me, I might jump on the NT once it progresses further or I'm seriously considering the yet to be released Asus MeMo 370. That looks like it's gonna' be one sweet scoop of ice cream at a very nice $250 pricepoint.

Again, sorry for the OT but it's somewhat related. ;) Take care and thanks for your continued work here.

EDIT: On a sidenote, mrg666 just released a new mirage build. He does some good stuff! :D

Bootlooping on CM7 (CM9 is fine)

The native emmc recovery boots, CWMR on card boots and native OS on emmc

(1.4.1) all boot fine.

Any idea on how to fix this?

CWMR card still doesn't backup all (system and data for both OSes) the partitions though.

Only real change is my hardware was updated (warranty replacement) to one

that has the new emmc partition layout in support of 1.4.1. 1.4.1 boots properly

though. CM9 also boots off card. did I somehow mess up physical partition 1

on the card so it can't find the ramdisk / kernal images?

updated:

I tried to repair them by replacing two files, but that did not work.

Since there doesn't seem to be a way to mount the file systems

(data1 and system1) have to get the data saved and then rebuild

card and copy back to the apps and all.

Can I use adb with the existing CWMR to adb pull the 2 partitions

(file systems) to the laptop. Will adb shell mount the partitions

if I remount / rw and define a /data1 and /system1 mount point.

I wonder how I got stuck in the boot loop. A newly created card

worked fine (that's where I got the 2 files from).

something needed got either frozen with TiBu or removed,

because the tablet can't even load the app manager.

-Download the zip and place it on the SDcard partition of your DualbootSD rom

I downloaded the updates and I am still uncertain exactlly how to do it....

How do I place those in the SDcard partition when all my computer sees is the boot partition. I look at it with Mini Tool Partition Wizard and see the SDcard partition, but how do I get any files into it ???

I certainly want to try the updates and see if they are more stable for my NC

Tinpau
[Nook Color Android Development] racks11479:
Are you able to use ADB? if so please follow the steps below:

-Boot to the clockwork recovery included with the dualbootsd image

-Now on your PC/Mac goto terminal and perform the following commands:

$ adb shell
# echo /dev/block/mmcblk1p7 > /sys/devices/platform/usb_mass_storage/lun0/file

-This will mount the /sdcard partition to your PC/Mac

-Now copy over what files you want and make sure you unmount drive before disconnecting the nook from your pc

-Exit out of terminal emulator

-Now on your Nook while still in recovery, goto "install zip from sdcard"

-Choose zip from sdcard

-Choose the zip and flash away

-Reboot when done!!!!

That's it!!

What I have realized is that doing this with anything other than a Linux type box is a task worse than Sisyphus's. All of the people here mean well, but they just don't live in the same world as PC users, and PC users are not up on all the jargon, command line and developer/programmer software environment tools requirements to follow along with tasks suggested.

So what I found that works well is this: http://xdaforums.com/showthread.php?t=910008 I hope that it helps. You will have to ask questions in that thread if you have issues. Good luck.

I had posted a day or two ago about new problems with wifi on MiRaGe. I am happy to report that with this new update, wifi works perfectly fine on MiRaGe. I never had a problem on CM9, and it is still working fine with the new update. Thanks given, Racks.

Is it possible to tether over Ad-hoc with the ICS rom you compiled? I still can't grow away from my dinosaur Sholes.
[Nook Color Android Development] webdroidmt:
Racks, thanks again for the new release. Installation went very smoothly, only thing I'm noticing is that CM9 seems very slow and laggy.

I've got it OC'd to 1.2 same as with prevoius versions but it definitely feels "sticky" with browser scrolling and transitions between home screen and app drawer screen.

Oh well, I'm sure later builds will improve on this.

Hi, racks,

I've never used your dualboot image before, and since you've updated both cm7 and cm9 zips, is it ok to boot into uRecImg/uRecRam and flash Update-Mirage_CM7_DualbootSD_02012012.zip and Update-Encore_CM9_DualbootSD_02012012.zip first, then follow the instructions you posted, Instead of complete your instructions then apply the updated zips?

Yes, it should be fine to just flash that first then concurrent necessary zips for gapps.

[Nook Color Android Development] mechanic54:
After flashing the new zip, my GB install is in a startup loop...

I copied the 2 new zip files to the sdcard

I then booted into revocery

I flashed the ICS update

I flashed the GB update

I flashed gapps for ICS

I flashed the ICS fix

I flashed the gapps for GB

Booted into ICS - long story short I again received the calendar has stopped errors

I booted into recovery and cleared cache

Booted into ICS again - still get calendar has stopped error

stopped calendar sync

went into the calendar and calendar storage and cleared data

started calendar sync again

now calendar synced and all is working fine

Booted into GB - everything gets a force stop error.

Booted into recovery again and flashed just the GB zip

Booted into GB and get a a constant startup loop

What is wrong, can anyone enlighten me?
[Nook Color Android Development] webdroidmt:
Thanks for the tip, Dave. I did cache/dalvik before I flashed the new build but I'm guessing you mean after it's installed? I actually reflashed this morning and it does seem a bit better but still laggy, especially on the screen transition for the app drawer.

I also have a CM9 install on my HP Touchpad and it is so much faster, so maybe I'm seeing an unfair comparison. But, I could've sworn that my NC was much faster with earlier builds.

Well, I'll try clearing it again to see if there's an improvement. Thanks again.

Mike T
[Nook Color Android Development] bretzke:
I did mean to clear the caches after install.

I did my install/update last night too and am seeing the same lag...especially noticeable, just as you mention, when you open the App Drawer. By no means horrible, but noticeable. We just may be at the limits of the hardware.

The only problem is that I tried to take my own advise. However, I cannot seem to clear the dalvik cache. I've always done this in Recovery. But when I try now, I only get an error in this triple boot setup. Any way to clear this while booted in CM9 or is there another option?

UPDATE: I found what appears to be a dalvik cleaner in Titanium Backup. Did it and rebooted. No significant change.

Thanks!
[Nook Color Android Development] michaelg1030:
How stable is this build? I was using cm7 than I moved to the ICS night lies, but they are just to buggy for everyday use. Is there anything that doesn't work? Thanks in advance.

New IMG file ??? Please ... Racks

I am very happy that Racks has updated the zips for CM7 and CM9, and that we can flash the new roms. :)

But I am having a heck of a time getting into my SDcard partition and putting the new zip files to flash there...

I am asking that if it is at all possible could Racks or someone else please create a new updated with the latest roms IMG file??? It is so nice to just burn that Img file to the sd card and start....

Thanx and I hope it is not too much a pain in the butt .....

Tinpau
[Nook Color Android Development] webdroidmt:
Yeah, I used the dalvik cleaner in TB also, no noticeable difference. Actually, the lag seems to fluctuate and at times the NC is fairly snappy, only to go back to lagging again. It definitely seems to gain some speed after initial boot, maybe it's building up cache or something as it's being used???

I d/l Autokiller Memory Optimizer from the market and it seems to have made a small improvement in keeping things less sticky, along with NO Frills CPU @ 1.2. Although, that may just be placebo. :D

I'm hoping that as development progresses with acceleration, codecs etc., we'll see the abilities of the NC stretched just a little bit more.

[Nook Color Android Development] smarcin:
Here's what I did:

Copied both updates to my uSD.

Booted into recovery.

Flashed MiRaGe update.

Flashed gb gapps.

Booted into MiRaGe.

Connected to wifi.

Booted into recovery.

Flashed ICS update.

Flashed ICS gapps.

Flashed the gapps fix.

Booted into ICS.

Connected to wifi.

Then you can boot into whichever one you want. Note, when you reboot from recovery, it often boots to the native B & N OS. Just shutdown and reboot.

This is what worked for me. Some don't even flash gapps without a reboot, but I've never had a problem. I just wouldn't flash stuff from both MiRaGe and ICS without rebooting in between.
[Nook Color Android Development] tinpau60:
Sounds easy...

Well I looked at everyone's response and read them all and tried them all... but no success ... I know I am a smart person, and this cant be that hard... but it is..

Tried using the Driver Pack and getting that running ... cant tell if it works or not the screen closes so fast and I don't see any sdcard partition available.

Tried emailing the files to myself.... files are too large to attach...

Tried dropbox but cant get Nook to use it and if I try from the computer to put it on the card again I cant see the sdcard partition.

ARRRGHHH ... Little old ladies (no offense) are putting CM7 and/or CM9 onto their nooks.... and having perfect success... God I am frustrated.

I thought putting all the image files and zips on a sdcard and running from that would be easy...

This dual/triple boot is the only thing that has worked at all for me ... now I want to use Racks updates and I cant even do that.

Sorry for the rant...

[Nook Color Android Development] racks11479:
Really am sorry for all the trouble you're having with getting the zips to the SDcard partition. Couple questions.

Nova Launcher

@bretzke

Hi Dave,

Don't know if you've tried Nova Launcher for CM9 but give it a shot. It seems to be much smoother overall than the default Trebuchet launcher. I've been using it since Sat night and it doesn't seem to lag as much with screen transitions and the app drawer.

[Nook Color Android Development] bretzke:
I haven't tried it yet, but will now. I never thought it was a Trebuchet issue, just a low RAM or running from a SD card issue....though I using a SanDisk 32GB class 4.

Thanks!

Dave
[Nook Color Android Development] webdroidmt:
I tend to agree with you on the Ram being a factor, not so sure about SD card or eMMC though. When I've had builds of CM7 or CM9 on either of them, I've never noticed any visible speed differences.

Now, the only time I did notice a speed difference was when I had a CM7 build on a 32gb SD card. But that card was a PNY class 10, not a Sandisk and the NC definitely seems to favor Sandisk SD cards.

Try Nova and post back what you think. I don't think it was placebo on my part, so I'd be interested in your take on it. Probably others on here would be interested also. Take care.

[Nook Color Android Development] vejur79:
I had the same problem and this is how I finally did it. All it required was the installation of a third party file manager like ES File Explorer or File Expert.

Download the updates to your PC.

Boot to the

NOOK Color

side and connect it to your PC. Then transfer the update file(s) to your NOOK to somewhere that is easy to remember. I put mine in My Files - My Downloads.

Now, boot to Android side. (Mirage or ICS, wherever you have your third party file manager program installed.)

Start up your third party file manager and make sure you have granted it root access. (I'm not sure if root access is required, but I have it on ES File Explorer and it seems to work.)

Navigate to emmc.

Go to the location where you transferred the file(s) in Step 2.

Copy or Move the file(s) to the root directory of your sd card.

Boot into Recovery and you're good to go.

Hope this helps.

Ron.

What a clever idea! I don't have to worry so much, as my main desktop is a Mac and I can see both Boot and SDcard. And my old laptop and my newer netbook both are dual boot, with XP and Linux. But if I didn't have an alternate OS to work with, I would definitely use your tip. Your idea is GENIUS!

I installed and updated CM7 (GB) using the 2/2 update in the second post. All seems to work A-OK. :)

However, with the CM9 (ICS) install and even with the 2/2 update (Update-Encore_CM9_DualbootSD_02012012.zip), I experience a great slowness while downloading anything from the Market. I mean, it downloads in KB/sec not MB/sec like with GB or my other android devices.

I do experienced a general sluggishness using CM9, but that appears par for the course it seems. I've tried setting the CPU governor to on-demand and 1200 Mhz, but that only helps marginally and only when the downloading is sent to a "background task"!

Anyone experiencing the same ICS Market slow download speeds using this CM9 ROM?

Thanks a million to everyone that worked on this project.

I installed it per instructions, and had no problems for me.

Did it a second time to increase sdcard size and resize cm9 parts.

Learned more about my Nook Color, run it a 1325mhz and all is cool. :cool::cool::cool::cool:

Unrooted my Nook Tablet and reset it back to factory software and applied 1.4.1 update. And now I wait for dual boot for it. Or just cm9.

But NC is number one again. NT is back to number two.

OK I've been reading the forums for days now awaiting my new NC, which finally came today :D

No major problems with initial flash. Hoping I did the updates correctly. I copied the update files to sdcard folder after going to file manager in CM7 and turning on USB. then reboot to recovery and installed the updates, once the 3 updates were installed I rebooted.

During testing, after updating I noticed in CM7 I couldn't get into Market, but was able to get into it before updating.

Anyone know what I should do to fix Market?

If this doesn't belong here, Mod plz move it to the right area

My question is about cache and dalvik cache on this triple boot setup...

Do all of these systems (Stock on eMMC, CM7 & CM9 on mSD) have their own cache and dalvik spaces or do they all use a common cache/dalvik cache space, presumably on eMMC?

I was wondering when flashing/reflashing whether the I am actually clearing these things when I want/need to. I guess yes would be the anwser if they all use a common cache but probably not if they all have separate spaces.

Using the experimental CMR included in Racks setup, I get and error attempting to clear the dalvik saying directory not found or such.

Thanks for any insight.

Has the tailored CWMR been fixed for the 7 part layout?

I wondered if the CWM had been fixed?

Thanks
[Nook Color Android Development] racks11479:
-Both roms on the dualbootSD share the same cache partition 'mmcblk0p7'. On next updates maybe I'll create a different mountpoint in 'mmcblk0p7' for each rom. Just like how NookieFroyo did before.

-Each rom creates it's own Dalvik cache in the /data folder.

The reason you're unable to just wipe dalvik at the moment is because CWM is searching for /data in the mount point, something I overlooked. The dualbootsd mount points are as follows:

/boot mmcblk1p1
/system1 mmcblk1p2
/data1 mmcblk1p3
/system2 mmcblk1p5
/data2 mmcblk1p6
/cache mmcblk0p7
/media mmcblk0p8

/data1 is CM7, /data2 is CM9. I plan on updating the CWM for DualbootSD when I have a chance. Have to rework some code to wipe the correct partitions. Hopefully I'll have sometime this weekend.

Putting CM9 Nightly Builds on DualBoot

Racks,

I already know that you prepare any build updates specifically for the dualboot setup and that if I try anything, it will most likely screw things up. That said, is it possible that I can take a CM9 nightly and simply replace the META-INF folder in the zip with your CM9 META-INF folder and flash? I won't be surprised if it isn't that easy.
