[Barnes & Noble Nook Tablet] Merazomo:
Yeah, I guess that's too much of a hassle for me. Do you recommend Nougat for my Nook Tablet? Have you tried it? How stable is it compared to CM13.
[Barnes & Noble Nook Tablet] carefreeway:
[MENTION=5989831]Merazomo[/MENTION], I haven't tried it because I have analogous tablet with only 0.5 GB RAM (To upgrade it I need at least hot air gun and 1 GB chip). As you can see from above posts I have asked others about memory info on this firmware to estimate is it worth it to build a new firmware for my device. It doesn't worth it without hardware upgrade in my case.
[Barnes & Noble Nook Tablet] Merazomo:
I have a 8GB BNTV250A Nook Tablet, and after futilely trying to install the Pico Gapps (always installing 94 out of the possible 95 apps and failing at Google Play Services in each of the 20 different packages at startup that I have tried) I've decided to use the tablet without Gapps, and use alternative F-droid applications.

There is a question I've been wanting to ask, but I don't know anyone personally that owns a Nook Tablet. I have two Nook Cables. One cable turns the LED indicator light Red, even when I'm not charging anything; it just needs to be getting power for it to turn the light on; it then changes to Orange/Amber when charging, and finally turns Yellowish/Green when the tablet is fully charged. The other cable's LED light is always off even when getting power, it then turns on to Orange/Amber when charging, and finally turns Yellowish/Green when the tablet is fully charged.

Does anyone know which cable does the right function? It's been so long, I don't remember if at some time they both did the same thing. I don't want to be using a shorted cable and damage the Nooks.
[Barnes & Noble Nook Tablet] carefreeway:
[MENTION=5989831]Merazomo[/MENTION], you can use multimeter to check your cables.

With all traces of CyanogenMod.org gone, where can I pick up CM 13.0 for my Nook (acclaim).

I need to redo my tablet as it became corrupt and will not boot after 2 years running LiquidSmooth...

Thanks!
[Barnes & Noble Nook Tablet] mikeataol:
I have been using an early Nougat release from [MENTION=4473900]amaces[/MENTION] for a long time.

He did acclaim users a huge favor by porting it along with the HD and HD+.

see : https://xdaforums.com/nook-hd/development/marshmallow-nook-hd-hd-t3239269

just my experience... This 7.0 version has none of the issues developers are seeing with the newer ports, or if it does, I'm not seeing them.

I have uploaded it to mega for you as he dropped it from his repository some time ago .... use opengapps.org to add gapps for 7.0

you need a TWRP 3.something.... which I assume you have.

my experience has been to wipe, install the rom... reboot to recovery, install the gapps.

https://mega.nz/#!nQwiEILS!dm7i-4AOUzYW5yP0LaqcZ5EAUsxeh-Qr8DULB4BGYZ8

after install, to get Superuser functioning you need to add the opensource version of su interface from the play store.

https://play.google.com/store/apps/details?id=me.phh.superuser

sorry for all the edits.... I have assumed also that you have a 16GB Nook Tablet. I haven't seen release within the last few years that runs well on an 8GB model.
[Barnes & Noble Nook Tablet] JMaejr:
Yes I do have the 16GB...everything was fine until a couple days ago, tried updating my kindle app and suddenly everything was broken.

I suspect somehow something got corrupted as it was stuck in a boot loop and would immediately crash when I touched the screen, if it did manage to boot, then the process would repeat...

I will give your suggestion for Nougat a try. Thanks so much for uploading it; that's the bad thing about so many of these guides is you cannot find the files...and of course I lost mine years ago.

Thanks again!
[Barnes & Noble Nook Tablet] nmyshkin:
I've been lurking on this thread for awhile trying to decide what I want to ask. With all the CM stuff up the flue, this seems to be about the only game in town other than succulent's CM 11 builds.

I'm currently running CM 12.1. It's "ok", but a bit flaky at times. No major problems, just a little sluggish at times. Occasional shutdowns. So, ok, the device is old. I'm wondering about this CM 14 build. There seemed to be a lot of issues with CM 13 and that scared me off. What about CM 14? Can you compare it with CM 12.1? Is there an advantage to moving to CM 14 other than the gee-whiz factor? (there aren't any apps I currently want to run that need it and I often freeze updates on apps that perform better for me in an older version).

The whole repartitioning thing gives me the heebie-jeebies. I had my tablet repartitioned at B&N before I ever did any ROM flashing. I'm guessing that's not enough :( But if I got buyer's remorse from CM 14, I guess I'd need to repartition again?!
[Barnes & Noble Nook Tablet] mikeataol:
If you are on a 1GB/16GB Nook tablet,

The Nougat 7.0 I posted in the mega folder runs fine for acclaim , without the shutdown/reboot, and video playback issues that all the 7.1/7.1.1 roms are having. (not just Barnes and Noble tablets, the KIndle roms I've used are seeing the same things) Its AOSP which is just less customized than CM versions of Android.

If I am handing a tablet to an end user , that's is the version I use.

Stock partitioning is fine for [MENTION=4473900]amaces[/MENTION] builds, (like the 7.0 I posted above) , the re-partitioning in choffmans semi-official is not necessary. ( and you often have to take extra steps to get it to work. )

In my opinion , any of the 7.0 / 7.1 / 7.1.1 builds are better than a CM11 rom, but I haven't used a succulent build in a long time.

if you are on a 512MB/8GB tablet, I don't know of any roms other than succulent's that run acceptably.
[Barnes & Noble Nook Tablet] nmyshkin:
Yes, I'm running a 1GB/16GB tablet. So it sounds enticing. As far as the procedure, is it parallel to flashing say CM 12.1, with an updated TWRP and GApps? And if I screw up or hate it, could I just use my CM 12.1 SD card backup to return?
[Barnes & Noble Nook Tablet] mikeataol:
I don't think you'll hate it....

if you need to find the relevant TWRP, I have attached it as a zip, don't unzip it, just rename it to .img after you save it. it's not a zip, it's an .img

from the cyanoboot screen, enter fastboot mode.

from the pc with working adb/fastboot.... " fastboot flash recovery twrp-3.0.2-0-acclaim.img"

end fastboot

reboot to recovery, flash the rom...

reboot

flash the appropriate opengapps

I don't know what's on your cm12 backup. is it a CWM based recovery or TWRP?

if it's a TWRP backup I suppose it will be fine, you could also do a TWRP backup after flashing the newer TWRP
[Barnes & Noble Nook Tablet] digixmax:
FWIW, in case anyone is looking for an old CM13 snapshot, cm-13.0-20160819-SNAPSHOT-ZNH5YAO0IN-acclaim.zip is archived at https://archive.org/download/cmarchive_snapshots.
[Barnes & Noble Nook Tablet] nmyshkin:
Bear with me here as this is very different from what I've done to get CM 10.2.1 and 12.1.

Am I right that this fastboot procedure is overwriting the emmc recovery? (which I think might currently be CWM). If so, then I would be booting into emmc recovery afterwards and flashing the new ROM from the SD card?

I'm used to working with SDC, booting from the card and using the recovery on the card (which is TWRP right now), making backups on the card, etc. Is there any reason I could not approach this in the same way? In other words, could I prepare a bootable card with the new TWRP as "recovery.img" and do what I usually do (I never use the emmc recovery, so maybe just leave that alone--ah.......the TWRP you supplied is an img, not truly a zip, hence the fastboot routine?)

Just trying to wrap my head around this before I end up with a doorstop :eek:
[Barnes & Noble Nook Tablet] mikeataol:
re: updating

______________________________________
[Barnes & Noble Nook Tablet] digixmax:
Instead of using the fastboot method, you can use your existing EMMC or SD recovery to flash the new recovery -- but you'd need to have the new recovery "wrapped" in a flashable zip file. Unfortunately CWM/TWRP recovery often don't get released in flashable zip form. What I had successfully done in these situations was to take the flashable recovery zip file of a recovery with version number relatively as close to version number of the target recovery as I could find, then used 7-zip to delete the recovery.img file contained in that zip file and re-inserted the new version of recovery.img -- thereby created a flashable zip file for the new target recovery.img.
[Barnes & Noble Nook Tablet] nmyshkin:
Just a few more questions and then I'm good to go.

You don't mention a TWRP wipe&factory reset before flashing the ROM. Good/bad, necessary/not?

I thought I caught a mention of SU earlier in this thread so I assume the ROM has a developer option to enable root?
[Barnes & Noble Nook Tablet] mikeataol:
I always wipe as a matter of course. system is probably not necessary but I do them all (system/data/cache/dalvik)

you probably also want to convert your /data partition to f2fs file system before installing (reboot to recovery after file system conversion and before rom install)

(also don't forget a reboot to recovery after rom and before gapps install)

SU is built in to the AOSP variants, there isn't a developer option like in CM, but you do have to add the phhSuperuser app as posted above to make root work in the :"normal" way

(in: https://xdaforums.com/showpost.php?p=71077169&postcount=254)

otherwise su would only be available in adb or command line environments.
[Barnes & Noble Nook Tablet] nmyshkin:
Finally, a devil in the details (there are probably more...). I searched for this in the forum but didn't come up with a lot. I'm guessing this has something to do with speeding up things a little (or at least making them more efficient)?

1. is this necessary?

2. is this "destructive", i.e., will this make it impossible to return to CM 12.1 by wiping and flashing with my prepared SD card?

3. how is it done?

Edit: oh, and at OpenGApps they have some sort of note on the 7.0 gapps...something about it requiring a patched ROM for proper WebView support? Have you noticed an issue?
[Barnes & Noble Nook Tablet] mikeataol:
converting to f2fs isn't necessary, I don't know if cm 12 supports it, but you can always convert it back. It's a faster file system. converting will erase everything In /data and /media (emmc)

its done in TWRP

wipe

advanced wipe

repair or change file system

(pick data)

change file system

I haven't noticed any issues at all with this 7.0 build. later builds there is a handful of niggling issues that are persisting even to the newest builds. That's why I use the 7.0 build.
[Barnes & Noble Nook Tablet] nmyshkin:
Your second cable (no red light ever) describes the one I have that came with the tablet.
[Barnes & Noble Nook Tablet] nmyshkin:
I thought I understood this and hoped I would not need it. But, of course, what happens when you reboot into Cyanoboot is that you lose that wonderful USB debug connection that would have made the fastboot dance a slam-dunk. And so here I am.

TWRP in a flashable zip?! I can't find any, certainly not at the TWRP site itself. Everything is an image file. The only thing I have that comes close is the CWM zip I used in going to CM 12.1. All the TWRP files I see in recent postings about installing CM x that are not also repartitions (and even those that are) seem to be images.

Can I use the CWM zip (as wrapper, of course)?? And why is it, exactly, that I can't just put the new TWRP on the SD card and use the SD-based recovery older TWRP to flash it to emmc? Another mystery :(

Edit: or can I just use something like Flashify to get the job done?
[Barnes & Noble Nook Tablet] digixmax:
Yes, you can. In fact (as I now recall) I could never find any TWRP zip file and had to re-use a flashable CWM zip file to create my flashable TWRP (v2.6.3.1 at the time way back when I still had my NT).

FWIW, I have just created flashable zip files for the last three versions of TWRP for acclaim (3.0.1, 3.0.2, and 3.1.0) and uploaded to https://www.mediafire.com/#xjwc1a482a6ll.

My understanding is the "install zip file" operation of CWM/TWRP recovery expects a zip file which contains the set of folder/file(s) to be installed ("flashed"), and a pair of update-binary and updater-script (which is located in the folder META-INF\com\google\android\ of the zip file) which get executed to effect the installation process. In the case of the flashable recovery zip file the updater-script has just three simple lines:

ui_print("Flashing recovery");
package_extract_file("recovery.img", "/dev/block/mmcblk0p3");
show_progress(0.100000, 0)

It basically just extracts a recovery.img file from the flashable zip file and installs it in the the recovery partition of the NT, which is why we could swap in any version CWM or TWRP where it expects to find a recovery.img file.
[Barnes & Noble Nook Tablet] nmyshkin:
Thanks so much. I did read about the set of files that belong with the flashable zips as I started to look at sites that described how to make them. And I had used Flashify to place CWM on my little KitKat phone I use as an mp3 player since no one had produced a bootloader for it, so I thought about that as an alternative. But the prepared zips you uploaded are even better :)

Too late to start now...tomorrow is the day!
[Barnes & Noble Nook Tablet] digixmax:
There is another, potentially simpler, alternative you might want to look into: using the TWRP App to install TWRP -- see https://xdaforums.com/showpost.php?p=58945605&postcount=1

Yup, one thing I've learned is never to undertake a non-routine upgrade late in the day. :)
[Barnes & Noble Nook Tablet] ehtisham ali:
Cyaonogenmod rom website is not exist now..could anyone upload alternativelinks?
[Barnes & Noble Nook Tablet] nmyshkin:
You are correct. I like it a lot, although I think I may have to try a different launcher because I can't deal with those huge icons and don't seem to be able to find a way to tame the size. I also miss the CM shutdown options from 12.1 (power, reboot, screenshot) but found a simple, free app that would give those back.

I have two issues which are unresolved and wonder if you've encountered anything like them. The stock browser would be fine except it seems unable to save any bookmarks! It says it has done so but then the bookmarks show empty. That's a non-starter. I'm trying to just keep it simple, but I could always install another browser. I just don't understand the issue and it worries me, just as the new-fangled SD card options rattle me a bit.

Also, I have a daily comics app that has always run flawlessly on systems ranging from JellyBean to CM 12.1 [Arcamax URLs require editing to change http to https]. It does not like this system. After looking at three or four comics it freezes. When you tell it to close, it goes back to the opening and will resume where you left off, only to freeze again after a few more. Very vexing. I thought it might be a WebView issue so installed the current app from the PlayStore but it made no difference. I've sent feedback to the developer, but just wondered if you'd encountered apps that would not run properly.

Overall I would say performance is positively sprightly compared to CM 12.1 and installing only the pico GApps means I don't have a ton of crapware to work around. Just these few little niggling issues........
[Barnes & Noble Nook Tablet] digixmax:
I'd suggest you give Nova Launcher a try -- lots of of tweaking knobs (although I need and have used only a handful).

I never like the stock browser much and always opt to use Firefox or Chrome, especially as they enable me to keep my bookmarks sync'ed across all my tablets/nettop/desktop.

[Barnes & Noble Nook Tablet] zswielder:
Hi.

I'm hoping that someone can help me. I have the 8GB version, and I have TWRP (3.1.1) installed. I'm able to install this ROM and Pico gapps fine, but once I get to the initial setup screen, the keyboard doesn't work right. It disappears while I'm typing, and it doesn't come back up. If I rotate the tablet and try, it sometimes comes back, but it's a big hit or miss. I can't get past the setup screen because of this, and then the tablet eventually crashes. I'm not sure what to do. The post says that re-partitioning the card is not required, but I'm wondering if I need to do that. Any help/suggestion would be appreciated.
[Barnes & Noble Nook Tablet] tjohnso1:
Hi,

coming back to this after a long time.....

i'm still trying to update my TWRP....i'm doing everying described here, but apparently my SD card is not seen (no longer seen) by my device, so I cannot access any of the zips or files.

Any clue why my device can't see the SD card?

thanks.
[Barnes & Noble Nook Tablet] digixmax:
What is the size of your SD card?

Nook devices have problem seeing SD card partitions that are larger than 16GB.
[Barnes & Noble Nook Tablet] tjohnso1:
I've tried two cards. One 16 gb, the other 128 gb. Both work in a PC, but are not recognized in the Nook....

---------- Post added at 12:09 PM ---------- Previous post was at 11:38 AM ----------

Hi, i also have a second nook color, which is working fine with CM.

I've just also gone into recovery with that one, and it has CMM-based recovery v6.0.4.8. I've put the SD car from the other Nook color (with TWRP v2.1.4), which is not recognzied by that Nook, and this SD card is recognized in this second Nook.

This means that somehow the first Nook (with TWRP v2.1.4) is not recognizing SD cards. It also does not start up in regular EMM, so i'm stuck....
[Barnes & Noble Nook Tablet] mikeataol:
The Nook Tablets can be finicky about the cards.

Class 4 Sandisk or other name brands seem to have always worked the best, and

there are a certain percentage that only see if you power off, insert the card, and then stick the charging cable in the device to start it, not by using the on/off button.

The issue is almost always the card, not the device...
[Barnes & Noble Nook Tablet] tjohnso1:
In TWRP i've just gone into the file manager, and there i can see the SD card, with the TWRP zip files and recovery. I just cannot see any files when i go via Install on the TWRP menue....

Any hints from anyone?

Note: there is no data on this Nook that i need, so if i can simply "reset" it, that might be the easiest? I'm happy to lose all data...
[Barnes & Noble Nook Tablet] mikeataol:
Have you connected to the computer while in TWRP recovery?

Do you have working adb on your computer?

in TWRP / Mount , disable and then enable MTP... if things are right you could then drop the rom directly to the device

or

the command "adb push romfile.zip /emmc/romfile.zip " will put it where TWRP can see it on the device as opposed to a card
[Barnes & Noble Nook Tablet] tjohnso1:
Yes, i can see the Nook device in my Device manager list when i mount it via the TWRP mount menue. (Win10 64bit). I do have ADB on my computer, i've sent the command: "fastboot flash recovery twrp-2.8.5.2-acclaim" but in my PC dos window i just get <waiting for device>.

See attached picture of my TWRP mount menue screen...I do not have enable MTP....
[Barnes & Noble Nook Tablet] mikeataol:
The tablet has to be in fastboot mode, not recovery mode for fastboot commands to work....

if you have a cyanoboot screen , there should be an option to put it in fastboot mode....

if in fastboot mode , and the PC Device manager has an exclamation mark, then you need to try a driver for ADB Android device.

I don't use 64bit Windows as often, but it can work.
[Barnes & Noble Nook Tablet] tjohnso1:
Something just worked! I've now got TWRP 3.1.0-0 on the device...not sure exactly how..

Now, if someone could help me quickly with the latest ROM....CM, or anything newer? I know CM is discontinued, so maybe something else?
