I've been waiting for so long to flash the CM rom and finally I want to do it now. I've been on stock ROM and not rooted, this greatly limited my usage on this tablet but gosh the standby battery performance was a blast (got 18 days and going)

Anyway, I checked the install CM 10 for dummies thread to see how to back up stock rom before I wipe it with CM, but I want the CM11 version too. My understanding of procedure would be as following, pls correct me if I am wrong:

1. make a bootable SD card with CWM recovery and I need to use the more recent ones (any more updates than the one in page 5?) for the later CM 11 install

2. boot into CWM recovery and choose to back up the entire stock ROM

3. Then choose install zip and flash the necessary CM11 files in this thread

4. Unplug the bootable SD and change for the daily use SD

I have a few questions:

1. I know CM11 is going into nightly release already, so I should go to that thread to download the most recent release or there is a more stable earlier release?

2. Do I need to always keep the bootable SD in the tablet or I could just swap it out after the flash. I asked this because in the "for dummies" thread, it seems like leaving the bootable SD in tablet is recommended? If that's the case then I will need to use my 64G SD for dual purpose (I originally just want to use a smaller SD for bootable SD only and then use a 64G for my daily use)

3. Later on if I choose to restore stock ROM, how should I do it? Plug the SD containing the backup files in, and backup from CWM recovery? Does the stock ROM use a different recovery and if it does, will the restore procedure get the stock recovery back?

Thanks a lot.
[Nook HD, HD+ Android Development] leapinlar:
Your procedure is right.

1. Use the nightlies.

2. Do not keep the bootable SD in the tablet. Keep the SD but not in the tablet. If my dummies thread suggests keeping it in the tablet, I need to modify the text.

3. To restore, insert the bootable SD, boot and do a restore. And the restore does not restore the stock recovery. To do that go to my HD/HD+ CWM thread linked in my signature and either flash my stock recovery zip from item 5 of that thread or the whole plain stock from item 6. To flash either of these zips you must use the older CWM from that thread. The CWM from this thread will fail when trying to flash them.
[Nook HD, HD+ Android Development] TheDannemand:
[MENTION=610362]procter[/MENTION]: One comment in addition to leapinlar's advice. You could use the image from his guide to create the CWM SD-card and boot that to backup stock. That same SD-card can then later be used to directly restore stock (from your backup or from leapinlar's stock images) no matter which ROM and Recovery you have installed at the time.

Once you've done that, flash the newer CWM from this thread to emmc, take out the SD-card, and reboot that CWM from emmc (you didn't mention this step). And now use that newer CWM to flash CM11.

Make sense?

[Nook HD, HD+ Android Development] metropolitans:
I got a chance tonight to test the CWM file linked on page 5 and it doesn't recognize my external sd card either. In fact it appears to be the same exact 6.0.4.6 version I already had on there. I just get a message that it can't mount the card.

I'm wondering, does the micro sd card have to be formatted a certain way for this to work?

Does anyone know if there is another emmc-based CWM out there for hummingbird that will work with CM11 and do a nandroid backup directly to the external sd card?
[Nook HD, HD+ Android Development] Classpro:
My 6.0.4.6 recognizes my external sd card just fine, and gives me the option on the backup page of backing up to the internal SD or the external SD. I can also install files from the external SD card.

My external sd card is formatted FAT32. Maybe CWM can't see your external SD card because of the way it's formatted?

The CWM on page 5 may be the same one on the first page - Verygreen may have updated it. Originally, the one on the first page did not recognize external SD cards at all. But I have not had to install CWM since I installed the version on page 5.

I am using HD+, not hummingbird (HD). I doubt that matters.

---------- Post added at 10:47 PM ---------- Previous post was at 10:43 PM ----------

Another thought - is your external sd card SDXC or SDHC? Many 64gb cards use SDXC. Maybe CWM can't read SDXC cards? I think there is a way to convert from SDXC to SDHC through windows, but I've never had an SDXC card. My card is 32gb SDHC.

Here's a link to a site about converting from SDXC to SDHC: http://gbatemp.net/threads/how-to-use-a-64gb-micro-sdxc-in-your-sdhc-compliant-flash-cart.335912/

[Nook HD, HD+ Android Development] rhyang:
I think I tried this last month with a card formatted as exfat, and cwm didn't mount it. Cm11 on the other hand could mount it just fine though. I put movies and such on a 64 GB exfat card, and use a 32 GB fat32 card for cwm backups and flashing.

One other thing about exfat I noticed was that the partition needs to be primary, not a logical partition for cm to mount it. Strange, because my nexus 7 using stickmount + fuse exfat support does not seem to care about such things.

In windows you can fiddle with partitions using minitool, among others.
[Nook HD, HD+ Android Development] metropolitans:
Thanks ... It was the exFat format! Everything else was working normally with my card, so I never thought the formatting would be an issue. I don't even remember formatting it as exFat, but I guess I did it to accommodate larger file sizes. I formatted it back to FAT32 for now. I plan to get a 64gb soon, so I'll do what you did and format that in exFat and keep a smaller sd card as FAT 32 for nandroid backups.

Also, thanks to king200 and classpro for your helpful suggestions.

Fantastic battery life!
[Nook HD, HD+ Android Development] jpisini:
Very nice.
[Nook HD, HD+ Android Development] procter:
Thanks for the reply. Is the bootable cwm SD card step the same as verygreen's first step listed in OP if doing new install. He had an initial SD image and said use windisk to write the image into SD and reboot to flash the recovery image. Sounds very like it. But I'm kinda confused at which zip to use, as the name was "cm-11-20140106-UNOFFICIAL-ovation-sdcard.zip" compared to an "EMMC" zip. I thought that's the ROM itself?

Anyway, another question is if the CWM recovery in pg 5 is already the newest, if not where should I look into for the updates?

One last question is, it seems like I will need to format the 64G card I intend to use into FAT32 for the recovery to recognize based on a few posts above. So basically it means Link2SD or Mount2SD won't work in our Nook HD+ (they require partitions formatted into exFAT AFAIK)?

Thanks again.
[Nook HD, HD+ Android Development] TheDannemand:
You were on the right path before I got you sidetracked :rolleyes:

The initial SD-card is the one you use the first time to "escape" from the stock experience (stock ROM and stock Recovery). It is a way to boot a custom Recovery (CWM) so that you can install other things (rooting the stock ROM or other utilities from leapinlar's threads, flashing a custom Recovery or flashing a custom ROM). You can ALSO use that SD-card to backup stock and even perform future ROM updates; but most people prefer to flash CWM to the internal EMMC because it's more convenient.

To create this SD-card you can either use verygreen's Initial ovation sdcard image (cwm) from the opening post of this thread (which is compatible with CM11) or the similar image from leapinlar's threads (which is compatible with CM10.x and leapinlar's stock images). And you can use Windisk or a manual procedure to create the SD card (leapinlar has great instructions in his threads).

My suggestion was to use leapinlar's SD-card image and a small SD-card JUST to backup your stock. Also download and save a copy of leapinlar's stock images (in case the internet should somehow cease to exist). Then keep that card safe if you ever want to restore to stock (using your own backup or leapinlar's stock images). You'll probably never need it.

But before you put it away, use that SD-card to flash the new CWM on your internal EMMC (ovation recovery image (CWM) from the opening post of this thread). Now you can boot that new internal CWM and use it to wipe everything and flash CM11 as well as any future updates. Use verygreen's instructions in the first post.

As for your 64GB card, you can then use that for general storage, including future backups (which can get pretty big) and flashing CM11 updates. Place the CM11 and Gapps files on that card. You just boot your internal CWM Recovery and chose install ZIP from external SD-card.

I am sorry if I confused things. In that case just ignore this. Really, your original procedure was OK, as leapinlar said...

Edit: Oh, don't use the cm-11-20140106-UNOFFICIAL-ovation-sdcard.zip file, it's for running the ROM from from an SD-card (while keeping stock on the internal). I don't think that's what you want. And I am pretty sure verygreen updated the opening post with the latest files, so you don't have to go to page 5.

Also, if you want to use Link2SD, use Recovery to partition the SD-card, creating an sdext partition (ext3 or ext4 when you install Link2SD). The rest will be FAT32 for general storage.

Upgraded to cm11 from 10.2 and so far so good. It really is much smoother. I'm running the GEL also and everything is working fine for me. The only snag I've found is that my Google calendar is no longer syncing. Might be due to dirty flash. Using paranoid android gapps stock released 2-13.

That 5 hours screen on time takes into account the other processes running as well as 5 day standby battery life.

Playing locally stored 720p mkv movies on loop, I get 10% battery drain for every hour of video. 75% brightness full volume.

I'm pretty sure 8-10 hours is doable with mixed usage.

Any way to get HALO into a CM11 rom? With a tablet, I'd really like some better multi-tasking capability.
[Nook HD, HD+ Android Development] mr72:
I don't get nearly that battery life playing various HD movies. It is about 2x that degree of battery drain. I am getting about 8-10% per hour battery drain just reading books using Moon+ Reader, that's no audio and about 5-20% brightness. I ran 17 hours reading books (screen on) with my Nook Color using Moon+ Reader and 10-12 hours of playing movies from SD. I am getting the feeling my HD+ has just about 1/2 the battery life of my Nook Color.

So what's the trick to get 8+ hours of movie playback at 75% brightness? If I can get there, I am sure I can get >12 hours of reading books.

Would it be too much to ask for this to be included in the next build?
[Nook HD, HD+ Android Development] metropolitans:
Thanks, but I had the correct CWM file all along. The problem was that my micro sd card was formatted as exFAT, which CWM won't recognize. Once I switched it to FAT32, it was recognized with no problems. .

CM 11 forgetting Wi-Fi password

Been running CM 11 for quite awhile now, but recently with the newer nightly's after shutting down & restarting the wi-fi password will have to be

re-entered, but if I revert back to the 1-27-2014 version that I have problem is gone, but this version causes other problems with screen rotation & seems like battery life is not as good.

I am currently running the 2-15-2014 nightly. I have tried other versions that are still available for download & I still have the wi-fi password problem.

Is there anything that I can do to correct this issue other then using the 1-27-2014 version that I have?

Thank you

[Nook HD, HD+ Android Development] leapinlar:
Root access is not the same as hidden files. Hidden files just have a dot in front to hide them. You need to find another setting in ES Explorer for root access.

Does anyone else experience the interface seemingly being very slow/laggy when shifting between apps and the home screen? I'm on the latest CM11 nightly and I'm used to my older KFire and G2x phone being so much more responsive in GUI related interactions. I've tried running the other unofficial versions listed and they're no better than the latest nightly since they both have all the fixes. Also the boot logo is so jerky and slow compared to my other old as dirt devices running CM.

I'm used to my 1st gen Kindle Fire and it might run things like crap but the GUI transitions are fluid and smooth. Both it and my HD+ are both running the same version of CM11 nightly. People using the HD non-+ probably don't experience this issue because your resolution is so much lower.

I turned GPU debugging on so I can watch the load. When it's laggy the graph has spiked to the maximum value during transition back to the home screen. It's almost like the entire home is being reloaded into memory. On my lower end devices there's actually a setting in the CM Performance section to lock home into memory to specifically prevent this type of issue.
