[ROM+Kernel] MiRaGe - Custom CM7.2 for Nook Color - 07272013

If not gapps, how do you install apps? Side loading?

I have a nook at the drawer, and if I can get it to run some browser and play YouTube it could be useable again.

I got mirage to flash, apparently I had to downgrade to twrp 2.3 (I was on 2.8, for cm11).

It's working snappier on the nook, but very limited in what it can do.
Seems like the integrated browser is capable of playing YouTube site. Just warnings about certificate authenticity. And not being able to do secured connections.

I'll see if this would get it out of the drawer and be used for something.

Edit: it's un-useable. Nothing can really work on it.
In the process of tinkering with it I got it reset to stock - a big mistake as I do not have the proper files now to hack it out of stock.
And it can't register as stock anymore, my guess the back end BN site not operational any more.
So this is now officially a tech junk, which I need to properly bring for electric recycling.
Sad moment.

Damn, that's rough. When going to stock, did you make sure you were on the latest version? Pretty sure I had to update mine before it would let me register. That really sucks. How did you go back to stock? My NOOK has literally no trace of the stock firmware because it was complete crap, so I flashed CM72 straight to EMMC.

That's what happens when you're not totally in focus while flashing. It flashed the stock ROM copy I had on my old SD, realizing the mistake only when it booted already.
Now, unfortunately I don't have the SD partitioned for alternate recovery, nor there's any valid link to download load those images again.

Nevermind, that piece of electronics did had a good run as a tablet for 3-4 years until my kids grew to demand better reactiveness and dumped it for a more modern tablet.

    I have been building/compiling my Nook Color's ROM from the CM repo. Besides the geek satisfaction, I build for removing some extras and customize for performance. This thread is for sharing what I build for myself with the community. Here is MiRaGe.

    Please thank/donate to CM project, especially the lead Nook Color developers, dalingrin, fattire, and keyodi.
    Thanks to Nick N, unibroker, Tool Belt, k8108, christoophat, deboyz1014 for their generous donations.

    - Synced with CM to include the FC fix with rotation. No Statusbar FC on boot anymore. I had tested this fix earlier and it was not preventing the statusbar FC. Now works, I missed something apparently.
    - Built an optional ROM with the full language set. If you don't need any other language than English(US) and Spanish, smaller ROM is recommended.
    - Synced with CM to include the rotation animation fix. Thanks to kalltkaffe for this brilliant fix.

    - Switched to modular kernel (see the previous update below), includes the SOD patch, and compiled with linaro 4.5-2011-10 toolchain.
    - Based on Dalingrin's encore kernel, built a modular kernel by configuring the uncommonly used features (they are still available) as kernel modules. There seems to be about 20% increase in the free RAM (available to the apps and cache) after first boot on my nook.

    - Just follow Eyeballer's guide.
    - If you are installing MiRaGe for the first time or upgrading after a long time, complete wipe is recommended.
    - When upgrading from a recent MiRaGe build, do wipe cache/dalvik-cache only.
    - If you do a clean wipe, you will need to flash gapps again. You can find it here or here.

    1) Regarding the status/notification bar force close issues, I recommend unchecking the "disable full screen" option in the Tablet Tweaks to avoid the status bar crashes. This also improves the app behavior especially movies and games that need full screen. To bring the soft buttons back in the full screen mode, I recommend Button Savior (available in the Market). If you had tried this app before, Button Savior developer greatly improved the app lately. When I enable autohide feature in Button Savior, it does not occupy any space on the screen. I just use the short swipe option at the right edge of the screen and bring the soft buttons when needed. Since I keep the soft buttons on the status bar, Button Savior is only used when an app goes to full screen mode. You can even remove the soft buttons from the status bar completely if you prefer an uncluttered status bar.
    2) If WiFi is not starting automatically on reboot, please see the fix in this post.

    Using ICS Launcher icons by kovdev. The clock widget is Sense Analog Clock.

    Disclaimer: I don't accept any responsibility for any kind of damage or loss. If you are going to report problems, please make sure that there are no mods or themes applied to the system. Also, SD installations are not supported since many problems are related to the performance of particular SD card. Only EMMC installation is recommended and supported. Before reporting any problem please try reflashing after a clean wipe.
    MiRaGe 11102012

    I have updated the ADW Launcher with the latest version which is working much better than the previous version. With only this change, I have bumped the build number to 11102012. This will probably be the final version of MiRaGe for Nook Color based on CM7 since the development has reached to saturation since some time. There isn't much left to do here. I am planning to base the future builds on CM10.

    MiRaGe 06232012

    I have uploaded the 06232012 build of MiRaGe after syncing with the latest changes in CM repo. Please check the OP for the download links, changes, and also the credits. Enjoy!
    This is an effort to reduce the way to get Mirage-Kang on the eMMC of a Nook Color to it's bare essentials. It will then introduce what some call "must have" refinements and hopefully give a glimpse into the enormous potential of our beloved NC. This is just a compilation, you have a lot of thanks to click before you click mine. If you would prefer to install to an SD card first you"ll want to take a look at verygreen's thread.

    1) Use Win32DiskImager to write the 1gb_clockwork- image to the boot SD hereafter referred to as the CWM card.

    2) Download encore_CM72-MiRaGe-11102012.zip and write it to the CWM card.

    3) Download gapps-gb-20110828-signed.zip and write it to the CWM card.

    4) Boot into the ClockworkMod Recovery.

    5) Once the device boots into the ClockworkMod Recovery, use the side volume buttons to move around, and the n button to select.

    6) Optional: Select backup and restore to create a backup of current installation of the Barnes & Noble Nook Color. Standard Caution: If you don't do a backup you won't have a backup. Excuse me, I'm gonna go do a backup,

    7) Select the option to Wipe data/factory reset.

    8) Then select the option to Wipe cache partition.

    9) Select Install zip from sdcard.

    10) Select Choose zip from sdcard.

    11) Select the encore_CM72-MiRaGe-********.zip.

    12) Install the Google Apps by performing steps 9 - 11 again and choosing the gapps-gb-20110828-signed.zip.

    13) Once the installation has finished, select +++++Go Back+++++ to get back to the main menu, (I use the power button as a back button), and select the Reboot system now option.

    14) Last thing before you hit reboot, pop out the CMW card and put your storage card in.

    The Barnes & Noble Nook Color should now boot into CyanogenMod. (It seems to take longer that first boot, don't sweat it.)

    eyeballer's thread
    mr72's thread
    mrg666's thread

    Some Settings to Consider:
    Settings, CyanogenMod Settings, Performance Settings:
    check Use 16bit transparency

    Settings, CyanogenMod Settings, Performance Settings:
    uncheck Enable surface dithering

    Settings, CyanogenMod Settings, Performance Settings, Compcache RAM Usage:

    Nook Tweaks, CPU Setting, Clock settings:
    300, 600, 800, 1000, 1200, check set at boot

    Nook Tweaks, CPU Setting, Voltage Settings:
    .925, 1.05, 1.2, 1.275, 1.325, check set at boot

    When you want to update...

    You shouldn't need to redo gapps or delete Dalvik cache.

    You'll notice that during the initial CyanobootMod there is an instruction to hold down the "n" for boot options. Since you're rebooting anyway why not hold down the "n" key and use the volume key to choose the eMMC recovery option. See? It looks just like CWM except slight wording changes. We want to make use of this and at the same time make SD Card swapping a thing of the past. All you should have to do is surf over to mrg666's thread and grab his latest from the OP. At this point I like to move it from the download folder to the temp folder but you could leave it in the download folder if you like. Reboot to CWM recovery option, wipe cache, select the appropriate folder and load the update ROM from it, reboot new ROM. If you where setting at your desk at work when you did this you may now go get a 'Born to Hack' tat during lunch and grin sheepishly the rest of the day.

    After that first boot I like to go to settings/about tablet to make sure it "took" then reboot just because I'm a geek that way.

    The above is the last Mirage-Kang update for CM7 don't forget to find a post of mrg666's and thank him.

    Qapla' Y'all!
    Any desire to tinker with CM9/AOKP builds? I know you build for personal use, but have you thought about starting an ics rom? Or are you waiting until the 3.0 kernel is fully functional? Your cm7 builds are super solid, just wondering what's holding you back from moving towards ics..

    I thought about joining the other developers. But if I leave CM7 there will be nobody left behind to cover the base. If you look at the changelog and user feedback, I did more than just building from the CM repo in the recent months. GB is not new and shiny like ICS anymore but I still enjoyed optimizing the CM7 build and overhauling the encore kernel. Plus I am also building for LG Optimus V. I simply didn't have time left for ICS. There is a little more work I want to complete for the encore kernel. I can try to help with ICS after that.I just don't like leaving incomplete stuff behind.
