You can find the microG links in the step-by-step directions in my post https://xdaforums.com/nook-tablet/general/how-to-cm-11-8-gb-nook-tablet-bntv250a-t3667555

Since I am just now doing a CM 11 configuration I've discovered a few things that are not in the instructions. Generally you want the most up-to-date microG components, even if they are not "stable" (I'm talking mainly about the gms core app). But for CM 11 the stable version (0.24) is what you need to get going. Newer versions hang on sign-in. After you are all set up you can replace 0.24 with the most recent nightly. Google makes changes now and again that require updating this component. You'll know if apps begin to whine that you need to update Google Play Services.

Also, the PlayStore version I suggested for the initial set up is over the top for CM 11. I've attached one from a Jellybean GApps package below. Google will just update it anyway. From my initial observations it looks like the real PlayStore app might be OK on CM 11 for the BNTV250a. If it turns out to be too cranky you can always get rid of it and use the Yalp Store app as described in the instructions. But if you want to try the real thing for awhile, you can stop at step 11--unless you want to enable Contacts, Calendar and/or Location.

Thank you for all your help. My Nook Tablet is functional again :)
[Barnes & Noble Nook Tablet] mikeataol:
Location awareness?

Hi Chris, I agree with the others, seems MUCH more usable than the 12.1 version so far

Does this ROM require a gapps to get network location functionality?

A: I loaded the open gapps pico version (50mbish) , I had to do a factory reset after that, ( as setup wizard crashed on reboot) , but upon factory reset and reboot network location came alive ...
[Barnes & Noble Nook Tablet] mikeataol:
I like it! A clear advance from CM12.1

Thank you Chris.

Issues noted so far:

minor: wifi doesn't automatically reconnect after a reboot, even after turning wifi off/on . After a reboot have to turn it off-on, then pick the SSID and "connect".

not so minor: screen casting/mirroring doesn't appear to work at all. (using a chromecast 2015) . Within YouTube works, within a cast aware dedicated player it works, but trying the native screen cast . to enable everything including non cast-aware apps to work, does not. Tried changing the DPI to a few different settings, did not make a difference. Settings screen sees the chromecast, connects for a brief moment , then disconnects.

Thanks again,

M
[Barnes & Noble Nook Tablet] mikeataol:
(sorry should have added above)

minor issue - recent apps doesn't have the "settings" to change from card view to grid view

minor issue - recent apps, bottom two cards block out the "clear all" function button

Insufficient Storage When Installing GAPPS

[MENTION=361777]chrmhoffmann[/MENTION] - I have done clean, and dirty flash of this CM13 ROM, After dirty flash overtop CM12 the ROM booted fine but GAPPS kept crashing, so I downloaded the PICO version of open GAPPS, it keeps giving me insufficient storage space error when trying to flash GAPPS. I have even tried the mini and micro versions of the GAPPS but with same result. ROM works beautifully but I would like to have access to the Play Store. Any ideas on a fix for this?

Also, I am using TWRP 2.8.1.0 to flash, and TWRP touch screen is all wonky. Everything looks normal in TWRP, but when trying to select folders that contain the files I am wanting to flash, it is pretty much non-navigable. Touches are misinterpreted and it takes forever to drill down to the particular file(s) that I am needing to flash. Is there a fix for this?

TIA - HTR
[Barnes & Noble Nook Tablet] PepeladZ:
Nice to have cm13 on nook tablet. I also had problems with gapps after fresh rom install, but one more factory reset fixed the problem. One question though - is it fine that system shows total of 668MB of ram instead of 1024?
[Barnes & Noble Nook Tablet] mac4rfree:
My current ROM is Liquid Smooth ROM. I like to update to CM 13. So i am flashing TWRP recovery 2.8.7.. and then i have to flash the latest Nightly..

Am i correct or anything else to be done?
[Barnes & Noble Nook Tablet] chrmhoffmann:
Yes, the "ducati" co-proc (used for video enc/dec) takes quite some memory away (amongst others). It's called "carveouts".

[Barnes & Noble Nook Tablet] chrmhoffmann:
Seems to fail somewhere with OMX video encoding. Was this (i.e. chromecast casting) working on earlier versions?

Chris
[Barnes & Noble Nook Tablet] mikeataol:
re: chromecast: "Seems to fail somewhere with OMX video encoding. Was this (i.e. chromecast casting) working on earlier versions?

Chris "

Its a new gadget for me, so I never tried it on the official CM12. I only tried it on one other rom, an unofficial 12.1 where it fails the same way.

searching the error I saw on a TI board where its likely to be a version mismatch, but out of my depth for sure.

re: wifi not connecting on reboot seems to have sorted itself out over time
[Barnes & Noble Nook Tablet] PepeladZ:
Thanks for info, Chris. Still i hardly understand why so much memory is used (356MB ). Interestingly, moto g 2nd gen with 1GB ram has 888 MB free for apps and os. Its quite clear, that around 128 mb of dedicated ram is quite sufficient for most uses. Can this be made tweakable on the end-user side? Hope my Q does not seem strange :)
[Barnes & Noble Nook Tablet] mikeataol:
Hi, The touch screen versions of TWRP for acclaim have always been screwy. You kind of have to very lightly tap, then tap again, to get the selections you want.

As far as gapps, all the system partitions I have seen are 650MB on a 16GB tablet, and the "open_gapps-arm-6.0-pico-20151203.zip" , 59 MB has gone in with no issues after flashing the nightly.

I dont trust the recoveries lately to clear things properly, so I manually clear system, cache, and data in an adb shell before building a new unit.
[Barnes & Noble Nook Tablet] mac4rfree:
Guys so finally I too hoped into marshmallow train.. I flashed cm recovery and flashed CM13.. Is root not available with this ROM?

And how to delete system partition and flash with cm recovery??
[Barnes & Noble Nook Tablet] mikeataol:
Root is available by enabling developer options, and there's an option for root

It's built in .

I haven't tried flashing this in a CM recovery...

But if you have cyanoboot already running, you can fastboot flash one of the newer recoveries pretty easily from the cyanoboot menu.

turn on fastboot

"fastboot flash recovery twrpx.x.x..recovery.img"
[Barnes & Noble Nook Tablet] digixmax:
Possibly (chrmhoffmann can confirm it).

You should never delete any partition or you will risk bricking your NT.

The /system partition typically gets reformatted (aka "wiped") automatically when flashing a new ROM, so there is no need to "wipe" it either.
[Barnes & Noble Nook Tablet] mac4rfree:
Well yes, i have flashed TWRP from fastboot and i wiped and reflashed again with Pico gapps.. The tablet looks so smooth.

But when i connect it to my laptop, i can see the tablet partition has only 4 GB. I understand from the first post, that 1 GB will be lost due to the partition but 4 GB was way low i felt.

Can somebody show some light as what am doing wrong or its the way it is?
[Barnes & Noble Nook Tablet] mikeataol:
if you at some time in the past repartitioned your device to what some think was the 'better" method, than you now need to repartition again. (your "media' partition was/is bigger than the old 1 Gb default.

theres a document in the first post showing what to do.

basically,

transfer the parted binary and make it executable

rm 10 and rm 11

mkpart a new userdata which will be 14GBish and all the flash will once again be used by cm13 as emulated storage

-----------

"RE-PARTITIONING IS NOT MANDATORY. IF YOU WANT TO RECLAIM THE 1GB PARTITION (called media) YOU CAN TRY TO FOLLOW THE RE-PARTITION GUIDE:

Anyone had any success running Marshmallow on BNTV 250A, the 8GB/512RAM Nook Tablet?
[Barnes & Noble Nook Tablet] nenitaj1:
Yes

Running great on my daughters.
[Barnes & Noble Nook Tablet] nenitaj1:
From cm7 til now....this is the smoothest ROM I've ever used. Love it. Is there a way to fix SD card issue? I'm trying to format SD as internal but it says my SD card is too slow when at 60%. Then when I go to settings and storage, it says SD is corrupt. Reformatting as portable fixes corruption. Is there a fix? I triedbon a 64gb and 32gb card.

Thanks
[Barnes & Noble Nook Tablet] ColinrB:
I'm jealous! Had all kinds of problems.

Did you update from KK? or Lollipop? Use TWRP or CWM recovery? What gapps?

I also had a problem with Marshmallow liking my 32gb SDCard. Said it was corrupted.
[Barnes & Noble Nook Tablet] nenitaj1:
I came from jelly bean. I used twrp. Wiped data, cache, dalvik, fashed rom. Then flashed open gapps 6.0 pico
[Barnes & Noble Nook Tablet] Juanito216:
Latest build runs well, but still having WiFi drops. Have to manually connect after.
[Barnes & Noble Nook Tablet] ParadoxGBB:
Well done

The nightly released 1/25 seems to be more performant / responsive than previous ones for me.

There's some posts online about CPU performance tuning in CyanogenMod but I don't see the setting, even after enabling developer options. Anyone have any luck?

+1 on the auto rotate comment earlier --- applications run in portrait fine but the home screens and application list are forced in landscape. That's not a big deal though.

Does anyone have any issues getting USB file access working on these builds?
[Barnes & Noble Nook Tablet] mikeataol:
The home screen rotation has to be set by pressing like you are going to add a widget, and then there is a menu with lots of options when you press the tiny triangle shaped thingie.

USB file access is had by dragging down the notification bar and tapping the message "USB for Charging". then changing it to file transfer mode.

note to chrmhoffman: the setting for USB storage mode has no effect on what actually happens when you connect a USB.

also +1 on the tuning options. don't see them here.

Battery drain

First, thanks for all the work that went into getting CM13 on my old Nook Tablet. I have been using my Nook HD and haven't messed around with this device in a while but my Dad was having trouble with his so I pulled mine out to help me remember the process of flashing a new version. I am running nightly 128. I put the device to sleep with 90% battery before bed, and in the morning it was down to 80%. Put it back to sleep and before bed that night is was down to around 50%. Is this normal for it to drain that much power in sleep mode? I have put very few apps on this so far. Is there something I can change in the settings to get better battery life?

Other than the power drain, things seem to be working pretty well so far. Maybe its just from the age of the battery.
[Barnes & Noble Nook Tablet] digixmax:
No.

You can go to Settings->Battery to see which apps/processes are the power hog.

Also, it would help to have WiFi off when the tablet is asleep.
[Barnes & Noble Nook Tablet] mogators1:
The only things listed under battery are Wi-Fi, Tablet idle, and Screen. I updated the setting for WiFi and will see if that helps. It appeared as if WiFi was sleeping before because when I woke it up, it was not connected to the internet for a few seconds. I guess it was probably still eating battery though.
[Barnes & Noble Nook Tablet] nandroid123:
CM13 bugs

I have CM13 running. Just some notes on what I have seen.

First the nightly recovery doesn't seem to work. When trying to install the update it fails every time. Doesn't matter which update method I choose. Won't find the external SD or anything. I had to revert back to a CM12 recovery to install. That could be a problem.

I noticed that when going through the registering process that it is quite different. I made sure that app restore was checked but it does not restore.

I also noted that screen rotate doesn't work no matter what. Auto rotate is turned on every where I looked. In settings and the hold screen pull up menu ???

Also I can't set a wall paper. Usually on first boot the wall paper is restored. Did not happen.

There are probably other bugs that I haven't found yet.

Hope some of these are fixed in the next nightlies.

But so far it seems very stable. Not like the last CM12.1 snapshot.

Good job Chris
[Barnes & Noble Nook Tablet] nandroid123:
bugs

After loading the latest nightly

The screen rotation does work initially. But after a sleep it turns itself off. And cannot be turned back on by the controls. Have to do a reboot to get it to work.

Still can't get it to restore Apps from internet.

Didn't try the latest recovery. Does it work yet ??? Had to use recovery from 12.1

don't seem to be many people posting ??? Maybe that's a good thing ????

One other thing. How do you get rid of the SD card notification in the upper left ? Annoying !
[Barnes & Noble Nook Tablet] ajbiz11:
Question: Is there F2FS support? I was about to repartition my device, but I didn't know if I should format ext4 or f2fs (I kinda wanted to try it out for once)
[Barnes & Noble Nook Tablet] mikeataol:
Yes

I have 2 tablets one, formatted f2fs, and one formatted ext4 (userdata partition)

The f2fs one scores 1000 points higher on Quadrant Standard benchmarks, primary difference is the in the IO tests.

I was holding off committing to f2fs because I initially read of filesystem corruption, but I have been running this about 3 weeks and haven't seen any signs that it doesn't work as it is supposed to.

I think you lose some (minor) disk space too, when using f2fs, as it appears the system stuff is larger on the f2fs machine.
[Barnes & Noble Nook Tablet] ajbiz11:
/cache is far fuller on f2fs, as it's just the way it works.

I'm going to attempt to enlarge my /system as well as reclaim the 1GB.

Does the ROM even LOOK at the ext_sd? Does Android M's new adoptable storage sd card feature work?
[Barnes & Noble Nook Tablet] nandroid123:
Is auto-rotate fixed in the latest nightly yet ? After the first sleep auto-rotate quits working until you reboot.

Yes I noticed that ever present SD card notification. Does it ever go away ??

Did the associated recovery get fixed ? Every time I tried to install the update I got fail.
[Barnes & Noble Nook Tablet] nenaj1:
Use twrp
[Barnes & Noble Nook Tablet] nandroid123:
I had to use twrp because the suggested recovery didn't work.

You let it go to sleep just once and auto-rotate quits working !!! Did this get fixed in the latest nightly ??? Doesn't matter what you do auto-rotate will not work without a reboot
[Barnes & Noble Nook Tablet] nenaj1:
I use an app called rotation control from the play store.

---------- Post added at 04:13 PM ---------- Previous post was at 04:09 PM ----------

Nope adoptable storage doesn't work. It says SD card is too slow at 60%. then shows it as corrupt. If I pick to move files...it says settings has stopped and crashes. Formatting to portable storage brings SD back to normal. I know this is an issue with cm 13 on different devices but most have already fixed the problem.
[Barnes & Noble Nook Tablet] nandroid123:
Why should I need an app for something that the OS should do on it's own ? So look for an app called rotation control ?? :p
[Barnes & Noble Nook Tablet] mikeataol:
I've loaded several machines, on about 6 different nightlies since the release, and the auto-rotation has never been an issue.

the only 2 settings I have ever had to change were:

settings/display and lights/ autorotate screen on, and 0/90/180/270 checked and in the

trebuchet triangle thingy menu , last option, allow rotation
[Barnes & Noble Nook Tablet] nandroid123:
auto rotate on latest nightly still not fixed !?!?!?!?!? What's the big deal ???

All those things you mentioned are turned on !?!?!??!?!?!

I would auto rotate until it went into deep sleep and then not !?!?!?

What am I missing !??!?!?!

You know I don't really have a big issue with it stuck in landscape mode. The problem is that I have some programs

that setup in portrait mode. And once it does that it's stuck in portrait mode until I reboot.

So what the hell am I doing wrong ?? Are there other auto-rotate switches that I'm missing ??

Why is this so complicated with cm13 ??????
[Barnes & Noble Nook Tablet] PepeladZ:
Could you post some screenshots. I've also tried every option (on/off) I could find and nothing works.
[Barnes & Noble Nook Tablet] chrmhoffmann:
What app are you using that triggers this?

Can you give logcat and dmesg?

I don't have the problem at all. So I don't know what to fix.

And it would be advisable to be a bit more polite.

Chris
[Barnes & Noble Nook Tablet] Zippy Dufus:
I had this problem. Look at this earlier post.

It wasn't too clear about swiping up but I finally fumbled into a settings menu to change to portrait mode.

Otherwise, a great ROM!

Thanks Chris.
[Barnes & Noble Nook Tablet] chrmhoffmann:
Yes, that's the launcher rotation. But some guys say it doesn't auto-rotate after some apps starting or after sleep. I don't have those problems for some reason.

Chris
[Barnes & Noble Nook Tablet] chrmhoffmann:
adopting sd cards as internal storage should now be fixed. thx to stargo!

Chris
[Barnes & Noble Nook Tablet] nenaj1:
I tried but still doesn't work. Any idea of what SD card was used?
[Barnes & Noble Nook Tablet] chrmhoffmann:
You need to wait for the next nightly build.

Chris
[Barnes & Noble Nook Tablet] nandroid123:
I'm not using any app that is triggering this. All that has to happen is for the nook to go to sleep.

I mentioned an app that uses portrait mode for it's setup. Google photos. So when the auto-rotate quits working

and you setup google photos then it goes into portrait mode and remains there until a reboot.

Do you let your testing nook go into deep sleep and you are not seeing this ? I heard others mention this earlier in this thread.

CM12.1 never did this !!

I am still using CM12.1 on the other 16gb nook that I have.

When I revert back to CM12.1 the problem goes away. But that version has a multitude of other problems.

CM13 seems really good except for this one thing.

There is one other app I use that needs portrait mode. vMEyePro. This is a security camera app that needs to set the cameras

in portrait mode. But this app only sticks in portrait mode after the auto-rotate has already failed.

Are there more places to set auto-rotate besides SETTINGS and the pull down menu ? Both are on auto and still not working.
[Barnes & Noble Nook Tablet] chrmhoffmann:
Yes. The launcher menu. Long press on the home screen. Then you should see three dots. Press on the dots. Then scroll down. There's auto rotate for the launcher. Not sure if this is related though.

Chris
[Barnes & Noble Nook Tablet] chrmhoffmann:
And does the rotation problem occur on the 16gb model?

Chris
[Barnes & Noble Nook Tablet] nandroid123:
Both of the nook acclaims I am using are the 16gb models. I do have a 8gb model but never had any success getting CM12 to run on it.

I try to keep one of my 16gb nooks running a stable version so I can use it. I had trouble getting CM13 to do the restore apps thing.

On page 5 of this thread a user nenitaj1 replied to me that he was having auto-rotation problems and used an app called Rotation Control.

I just tried that app and yes you can change the rotation with it. But when you set this app to auto it also fails to work !?!?

The problem is showing it self quite repeatably. Like I said above I have never seen this before with CM12 or earlier roms.

If I revert back to CM12.1 on this nook the problem is gone.
[Barnes & Noble Nook Tablet] steveh_131:
Great rom, thank you!

My only issue is the wifi not reconnecting after a sleep. Smooth and fast though!

Has multi user support been disabled for this rom?
[Barnes & Noble Nook Tablet] nenaj1:
I'm a she :)

I uninstalled rotation control and now the rotation works. Its auto. I didn't have to go into settings or anything. Are you using the latest ROM update?
[Barnes & Noble Nook Tablet] nandroid123:
I am using the February 5 nightly. Chris told me he didn't know what to fix. Which nightly are you currently on nenaj1 ??

thanks for posting

nandroid123
[Barnes & Noble Nook Tablet] nenaj1:
I forgot my user name then forgot I had already registered with Google before.

I am using the current cm-13.0-20160206-NIGHTLY-acclaim.zip.
[Barnes & Noble Nook Tablet] nandroid123:
Thank you nenaj1 for posting. So now we have at least 2 that have seen the auto-rotate issue. I will download the 06 nightly and see if that fixes the problem.

So nenaj1 did you have to delete the Rotation Control app before auto-rotation started working ? Or did you delete it because you didn't need it anymore ?

thanks again
[Barnes & Noble Nook Tablet] nenaj1:
I deleted the app then installed nightly 06. Now I'm on nightly 07. It was released earlier. Adoptable storage works now too! Sexiest ROM ever! Thanks to everyone who worked on this ROM. Best I've ever used.
[Barnes & Noble Nook Tablet] steveh_131:
Is the wifi issue still present, where you have to reconnect it every time it wakes up?
[Barnes & Noble Nook Tablet] nandroid123:
Auto-Rotation still not working on 20160207 for me

The auto-rotation feature is still not working for me on the 20160207 nightly.

I am at a total loss of what to do at this point.

Could this be because the custom recovery associated with the latest nightly does not work either ??

I had to get a CM12.1 recovery in order to install CM13.

I had been using the internal updater but found out it wasn't really updating !?!?!?

No matter what recovery I had in the emmc it would not update. No error messages at all !?!?!?

I'm just about to go back to CM12 until things can get sorted out.
[Barnes & Noble Nook Tablet] nandroid123:
There is something seriously different with this build. I have never seen auto-rotation fail like this.

Tell me what to do. I'll provide any and all the logs or whatever you need.

Has anyone seen the custom recovery along side of the rom actually work ?

As soon as I try to access the rom from the external micro sd I get fail.

Doesn't even show me what's on the sd.

All the custom recoveries up to CM13 always worked for me ???

If you need me to revert back to CM12.1 to prove there is nothing hardware wise wrong with my nook I will do that.
[Barnes & Noble Nook Tablet] nandroid123:
Ok now I have re-installed the CM12.1 rom back into the nook. Now everything works normally in respect to the auto-rotate.

I didn't have to do a thing to make it work normally.

So can someone please help me figure out why CM13 is giving me such problems ???
[Barnes & Noble Nook Tablet] nandroid123:
The nook is still working fine with CM12.1. No auto-rotate problems with 12.1. What the heck ???

This proves there is nothing wrong with my hardware. This is a software issue.

I can't believe I'm the only one with auto-rotate problems with CM13 ???

But there's still that issue with the custom recovery that you download with the rom. Never could get that to work ???

Guess there just aren't that many people using these old nooks anymore.
[Barnes & Noble Nook Tablet] nenaj1:
Edit: never mind issue fixed.

---------- Post added at 08:40 PM ---------- Previous post was at 08:36 PM ----------

Did u press and hold the home screen? Widgets and other options will pop up. You will see 3 dots. Press the 3 dots. That's how u can change the rotation.
