For Cyanoboot to be used internally it needs to be packed together with CM boot image and then the combined package installed into /boot (see http://xdaforums.com/showpost.php?p=25588117&postcount=8). The only NT CM7 build with built-in Cyanoboot that I am aware of is Succulent's at http://iamafanof.wordpress.com/2012/06/12/cm7-2-rc1-build-20120612/.

If you're looking for a CM ROM with better battery consumption than current/recent CM10's you might want to try ChrisHoffman's CM9 v0.05.3. CM9 is ICS-based so you'll get lots more compatible apps for your NT than with Gingerbread-based CM7.

I'm confused now. When I turn on my nook it goes into cyanoboot and loads the emmc. When I flashed the CM10 ROM it also installed cyanoboot, so can I uninstall it so I can install this CM7? http://xdaforums.com/showthread.php?t=1481826

I don't use that many apps, the ones I do use are compatible with gingerbread so I should be fine. I don't want the CM9 build because I want video hardware acceleration. My two problems with CM10 is the battery life and the way it renders pictures. I read manga and it seems CM7 applies AA to pictures while CM10 doesn't. I would post the screenshots to screenshotcomparison.com but it looks like the site's down.

Zoom done on the device:

What looks smooth in CM7 looks jagged in CM10. I looked it up and I think it has to do with what DPI android is set to. I noticed some of the icons in CM7 are a bit blurry and menus look bigger compared to CM10. How should I approach flashing that particular CM7?

Assuming you had used SD-based CWM recovery method to flash emmc CM10, in order to go back from CM10 to CM7, you can try the following (caveat emptor: at your own risk):

  1. replace recovery.img on the SDcard with the recovery version contained in CM7-9_CWM_v5.5.x_8gb-16gb_tools_sdcard.zip from http://xdaforums.com/showthread.php?t=1640958 (extract and rename new_cwm_recovery.img to recovery.img before copying it to SDcard)
  2. replace the previous CM10 zip file on the SDcard with the CM7 ROM zip file
  3. add to the SDcard flash_CM7-SR_CWM_v5.5.0.4_emmc.zip from http://xdaforums.com/showthread.php?t=1640958
  4. boot the NT to SDcard from power-off
  5. (optional: backup NT's current CM10 ROM)
  6. wipe cache/data/factory reset
  7. install CM7 zip
  8. install flash_CM7-SR_CWM_v5.5.0.4_emmc.zip
  9. remove SDcard, reboot (or power off then power on) NT

play store problems

I used cwm and put cm7 on my nook and everything worked including google market. About a day later though google market mysteriously disappeared. If I try to install play store it asks me to log into my account then all of the sudden it closes every time. how do I get it back correctly?


Thanks for reading.

Google Play is the updated version of Google Market.

I'd suggest you try deleting then re-adding account info in Settings->Account.

well, the working google store mysteriously disappeared.

I tryed downloading a google play store apk, and it installed. When I click the app, it says "you must add an account to the device to continue, do you want to add one now ? yes/no"

If i click either yes or no, both options close the program...

theres no way to get to settings for it.

Any ideas ? I would use cwm to redu the whole installation of cm7, but since the app mysteriously disappeared wont it just happen again?

ps, what is the best version to use of cm7 ?

I've installed the CM7 SDVersion (http://xdaforums.com/showthread.php?t=1481826) and it's very unstable (constant reboot), is there a solution or should I just update to CM10? (http://iamafanof.wordpress.com/2013/02/18/cm10-1-jellybean-android-4-2-2-for-nook-tablet-0218/)

My experience with CM7 (the Alpha version preceding the version you're using) was fairly positive, only a few occasional force-closes. A potential cause of the problems you're experiencing might be your SDcard's speed class. For running ROMs class 4 is best due to its read/write throughput optimization in favor of short & non-contiguous memory blocks, see http://xdaforums.com/showthread.php?t=1005633 for more detailed comparison & discussion.

Nevertheless I'd recommend you try iamafanof's CM10.0 build dated 12/31 http://iamafanof.wordpress.com/2012/11/18/cm10-0-jellybean-sdcard-img-for-nook-tablet/, it's very stable and has good battery performance although it does not have the latest bells-n-whistles of recent CM10.1 builds such as multi-profile support.

I totally concur with the previous post. Try a different card, different brand. And you don't need a fast one. many people found the standard speed ones work better for them.

Also, I see nothing wrong at all with the alpha CM7 version. Some people like to change to the latest and greatest. I prefer to stick with something that works unless the newer "thing" has some capability I really need (want?).

    To use ES File Explorer to edit system files, you need to go to ES File Explorer settings and checked "Root Explorer" and "Mount File System". To edit buid.prop, long press on the file and open it as text in ES Note Editor. Build.prop is in your system folder.

    For wifi problem,

    Try - edit your build.prop and commented out "wifi.supplicant_scan_interval = 20" by "# wifi.supplicant_scan_interval = 20".

    Not sure if it'll help with the random wifi drop.

    While you're there, change "dalvik.vm.heapsize=64m" to "dalvik.vm.heapsize=128m"

    Wifi calibration,

    Turn off your wifi and open up terminal

    # su
    # insmod system/etc/wifi/tiwlan_drv.ko <-only if tiwlan_drv.ko is not loaded, check by lsmod
    # start wlan_loader
    # ifconfig tiwlan0 up
    # wlan_cu -b
    # / w p 1 l 2 f 2 <-there is space between each character
    # / t b v 21
    # / t b t 1 0 0 0 0 0 0 0
    # / q
    # /system/bin/rmmod tiwlan_drv

    Now you can turn on your wifi.


    For mounting media partition,

    Try - edit your build.prop and add, "ro.additionalmounts=/mnt/media" and
    "ro.vold.switchablepair=/mnt/sdcard,/mnt/media".

    I don't know if this work, but in my CM7 build it work when you turn on USB storage. It will mount both sdcard and media partitions.

    For reading epub with Nook App,

    Copy your epub to /sdcard/Nook/MyDocuments and refresh in the app.

    Now that we've released CM7 again for the NT I thought I'd best start up a proper support thread. Pleas keep it as back reports and help.

    Please use this thread to post feedback and to ask questions. The Dev thread is for exactly that, development and not support! Please keep the development thread clear of support and feedback posts.

    Live support may be available on irc.freenode.net irc channel #nook-tablet-chat, if any of us are around we'll be happy to help but don't bug people if they are busy please. A web version of irc is available here http://webchat.freenode.net?channels=nook-tablet-chat


    When posting a bug or issue please use the following format

    • Which install are you using (Internal or SD):
    • What version is your CM7 download that you are using (should be alpha final now):
    • Do you have any mods on your NT (updates or system modifications)
    • If yes to above what have you installed
    • Where is this bug (main system or which application):
    • Can this bug be easily replicated:
    • If yes to above how can we replicate it to check:
    • Description of the bug
    • Any other information we may find useful


    Know bugs for Internal version will be in post #2

    Known Bugs for SD version will be in post #3

    I'm awaiting a Mod cleanup of this thread and all previous bugs up until the new release will be removed from this thread, should knock it back down to about 2 or 3 pages and give me the 2nd and 3rd posts I mention above.

    Bugs / Issues from the SD version

    System will reboot if you remove the SD card, this is completely normal and you should not remove the SD while device is running from it.

    Market will not work properly after the update unless you install the GApps (follow link in Dev thread)

    Wifi sometimes does no reconnect after sleep, simply tap on the status bar to get notification up and toggle wifi off / on and it should reconnect.

    There is currently no Reboot to Recovery option in the power menu, you can do this instead by going to rom manager (make sure it's updated via Market / Play)

    Mounts aren't working properly due to a typo on 2 lines in build.prop. search this thread for how to fix the issue on SD release

    There is still a possible issue with formatting. A member has said that asking the software to format the /media partition totally wiped his entire device completely removing the partition table creating a paperweight. As has been mentioned many times in both thread about CM7, if any formatting needs to be done please do it from a computer and if in the case of the Media partition that's not possible just delete files instead of formatting. Due to the risk involved we have not yet attempted to recreate this issue on our own devices!
