Finally here it is, the long awaited CM10 for Nook HD+ (early snapshot, anyway).
This codebase is currently hardcoded to work from sdcard only.
How to build from source (you need to meet all the usual cm10 build prerequirements),
Get the source:
(device repo on github)
(temp kludge for source kernel build: get my kernel from https://github.com/verygreen/green_kernel_omap and put it to kernel/bn/ovation (use ovation-3.0 branch for 3.0.31 kernel or ovation-aosp-kernel for 3.0.50), then put B&N source distro copies of wlan and wpan kernel dirs to external inside of kernel dir, and also desired version of sgx proprietary-open tar file into external/sgx)
Build:
In the out/target/product/ovation output dir you'll have the update file generated: cm-10-XXXXXXXX-UNOFFICIAL-ovation.zip
If you do not want to build from source, here's my current (as of this post, see bottom for newer versions) binary snapshot: cm-10-20130511-UNOFFICIAL-ovation-sdcard.zip
(additionally there's emmc version, follow installation instructions here, but use this install file: cm-10-20130511-UNOFFICIAL-ovation-emmc.zip)
You will also need updated cwm image: sdcard-cwm-early4.img.gz
For first time install only (you will need 4G or bigger sdcard, smaller ones are not supported and not tested):
gunzip cwm image and write it to your sdcard (entire sdcard not just one partition of it), use either dd on Linux/MacOS or Win32 Image Writer for those impaired by Windows. Make sure to use sdcard rated for fast small IO for best results.
(Note: There is now experimental recovery image that does not require adb that's currently documented in this post)
Insert the card into the Nook and reboot the nook, CWM should start.
(This will also automatically repartition the card into a correct layout no matter the size (but no smaller than 4G).
In the CWM:
Go to "mounts and storage", choose "mount /sdcard".
Press power button to go back to the main menu.
Now do
Also push whatever other zip files you want to install to /sdcard too.
(if you don't have operational adb, you can also just turn off the nook at this stage, put zip files to volume named "CM10SDCARD" (not "boot"), then put sdcard back into nook and start it again)
Next, choose "install zip from sdcard", and then "Choose zip from sdcard" and first cm-...zip, and then whatever other packages you have the need to install.
When done installing, press the power button to go one level up in the menu and then choose reboot.
This will reboot you into CM10.
If you ever need to get back to CWM later, use either "reboot to recovery" power menu, or reboot, and once B&N nook logo shows up, press and hold power and home keys together for about 4 seconds.
To reboot into stock nook software, just poweroff, remove sdcard, then poweron.
Caveats:
- Current sdcard layout is ~800M system and ~900M data for less than 16G and 2G data for 16G+ cards, the rest is a separate sdcard (because having sdcard to live on data is kind of dangerous). I am still taking feedback on these sizes better to change these early on while there are not a lot of users.
- This snapshot uses B&N binary kernel from 2.0, it happens to oops in mtp_open if you have mtp storage mode enabled and plug into a computer, so steer clear of it for now I guess, this will be fixed later. (if your nook reboots when plugged into computer or right on boot while plugged - this is it, likely to happen after first install).
- /cache is shared with stock ROM, helps for slower sdcards at the expense of slower boots when you switch your OS from stock to CM10 or back.
- Upgrade from 20121209 snapshot note: that snapshot had bad kernel that had problems with sdcards. Most advisable thing is to redo entire install (after downloading new, cwm-early3 image first). You might also be able to just install kernel from the update.zip and write it to the first partition on the sdcard, that shuld also fix all issues and will let your existing cwm to work to flash this new image.
Things that I know are not working:
- Coming out of sleep sometimes there's a crash (this is related to wifi, the workaround is to disable wifi while sleeping in the options).
- Rebooting to stock with sdcard still in causes stock to hang at 99% booting and sit there, simply pop out the sdcard and it will finish booting.
- on-headphones microphone is not currently used even if present (I now believe this is actually not a bug, and stock has the same behavior).
- Bluetooth signal strength is very low
- Hulu+ and other such things requiring DRM do not work.
This is now at feature-parity with stock B&N ROM, I believe (other than DRM).
Experimental versions:
Other than the stable version above, there are some experimental versions below that are tested before (hopefully) being promoted to the stable status.
01/07 version with a different kernel, otherwise same as 12/31
01/08 version with a recompiled B&N kernel, otherwise same as 12/31
01/19 version with a yet another different kernel, updated CM10 base and default dpi/screen size changes
02/12 Some CM10 changes from upstream and updated wifi drivers from B&N 2.0.6 code drop (hoping that it will fix the annoying coming out of suspend crash - nope, it did not.)
02/20 Don't reboot into emmc stock on crash, it does us no good. Revert Z-axis in accelerometer for hopefully better responsiveness.
wifi should no longer drain battery when sleeping, cover close will blank screen, gfx issues hopefully fixed
Enjoy.
