Thank you for responding.

I have followed the instructions in the linked thread word by word. I checked the links to links (couple hours worth of reading-not a bad thing though).

I image my sd card

I write the CM7 to my card.

I place sd card in my NC, and the penguin comes up.

Files start downloading.

Then it stops, and the message on my nook screen says "download the image file -description is given- and can be found at nook.linuxhacker.ru"

I cannot find a link to nook.linuxhacker.ru .

Google search reveals nothing including parts of the file I am supposed to download. Nothing

I would post in Verygreen's instructions, but I do not have enough posts.

Any help would be appreciated.
[Nook Color General] LarcenQ:
So after you write this image to your sd card:

http://nook.handhelds.ru/sdimage/generic-sdcard-v1.1.img.gz

You copy one of these files:

http://mirror.teamdouche.net/?device=encore

to the same card you just burned right?

Also, to make things easier, I add both the CM7 nightly build, AND, the google apps file to the sd card so both are installed at the same time:

This is a really great information thread for rookies. Im relatively new to android and the nook and i've learned so much from this one thread!

My two cents: currently running stock rooted and it is sufficient for reading web browsing and basic apps as well as watching videos loaded onto the nook.

As i get more comfortable I think ill give cm7 a shot. I tried nookie but had a ton of trouble installing gapps. Not totally comfortable with adb yet.

Thanks so much for the mature answers and help! Its really motivating to have a positive environment.

sent from my nook
[Nook Color General] LarcenQ:
I agree 100% on both accounts. I thought I learned some things before I made this thread; what I've learned since its inception trumps it by far, and a positive environment does encourage one to be a little more willing to go that extra mile when taking on daunting tasks such as rooting, flashing, etc etc etc.
[Nook Color General] Allsack:
Ok, I am doing something wrong, but I simply can not figure it out.

First of all, when I write the generic-sdcard-v1.1,img to my sd card (unzipped to desktop then written using win32diskimager) it makes a bootable partition on my sd card.

When I try to write the cm7 to the sd card, I get an error saying the drive does not have enough space. I look at the partitions using EASEUS, and the first partition is 117 mb, The file won't fit because it unzips to 130 mb or so.

I enlarged the first partition so the CM7 file would fit on the boot partition, but I still get the "cant find image file-download it (written up in my prior requests for help)

It's obvious I am doing something wrong, but have tried everything I can think of.

Suggestions?
[Nook Color General] LarcenQ:
COPY & PASTE the CM7 file to that boot partition. DO NOT write the file. DO NOT unzip the file.
[Nook Color General] Allsack:
O man,

Thank you so much.

Yes,,,, Worked!
[Nook Color General] LarcenQ:
You're welcome, glad I could help. :)

regarding button savior, description in market states rooting is necessary. If I am auto-nootered, do I need to do anything els special?

Softkeys just isn't cutting it for me.
[Nook Color General] bluewhite79:
nope got get button saviour. whats wrong with softkeys?
[Nook Color General] envygreen:
I think if you are using something all the time, I prefer softkeys. Right now though I have CM7 + the tablet mod running and have buttons on my screen as part of the UI except when a program overwrites it and goes full screen on me. Since Button Savior lets me turn it on or off quickly and easily, I usually close the offending program, start up BS, and then go back in and use BS.

And I gotta say, for those of you reading this thread and hesitating, stop. I was running a nice rooted setup and thinking it was sweet. (and it was)

Then I started with the honeycomb SD bootable, had some fun, but it just didn't feel finished. Then I got CM7 and the tablet tweaks. I honestly haven't booted back to my rooted install since then. It's an excellent experience, and if you don't like it or get stuck, you pop out the SD card, reboot, and you're back to start. :D
[Nook Color General] LarcenQ:
Amen. Started last Monday night with Honeycomb on SDcard. Meh, it was like riding around in a Ferrari on 4 flat tires and no interior.

Anyway, migrated to rooted nook 'stock'. We had a whole car then, just wasn't a Ferrari. Perhaps a souped up tuner car.

Come mid week, I was cruising around in a late 60's muscle car running CM7 #32 on SDcard. Very nice.

I took the plunge Friday night and installed CM7 #34 to EEMC and everything is sweet. Like a frame off restoration of the muscle car.

I figure by the time CM7 reaches 'stable' with an actual sleep state we'll have that Ferrari.

Now, envygreen, what are these tablet tweaks you speak of? Do they overwrite my CM7 install? Completely manageable around the CM7? If I update CM7 to a new nightly, do I need to start over? I desire knowledge, enlighten me.
[Nook Color General] rogerdugans:

That is the dev thread for Tablet Tweaks.

If you have a Ferrari now, put those on and you will go from having an old Ferrari with a couple of cylinders misfiring to a new one that works (almost!) to perfection!

The tweaks are an addition to CM7 that is under development: just hit feature freeze to get bugs fixed before releasing into the ROM.

It should be in CM7 soon. :)

It adds options for soft buttons on the status bar (pick the ones you want) and the status bar itself can be moved to the bottom. The buttons can be moved to left OR right side, whichever works better for you.

And there is a LOT more as well.

Seriously- as good as CM7 on the NC is these tweaks make it feel natural instead of a cell phone os on a tablet.

As for what it is:

Every time the dev has made changes/fixes/updates he compiles a new ROM based on the latest release source from the dev team.

You use this rom instead of the regular nightlies.

The oc kernel works fine with it.

There are still things that are not quite perfect, of course- the project is only a few weeks old, after all, but as it is right now it is excellent. Most of the problems that remain seem to be caused by apps that are coded badly- full screen behavior and handling, etc.

But there are easy workarounds for everything.

Button Saviour and Soft-keys are both good and help- the Tablet Tweaks (to continue the car analogy) makes them look like a Hyundai compared to the Zonda that CM will soon have.
[Nook Color General] LarcenQ:
Very good information, thank you. So, to elaborate on what you said, these 'Tablet Tweaks' will soon be committed to CM7's build(s)? That's perfect, I'll just continue cruising around in what I have and just continue to track the CM7 builds. There are -so- many threads on this site regarding this flavor and that, that it gets confusing trying to following multiple threads.

I love the 'honeycomb' effect with those buttons on the bottom of the screen, as well as, the notification bar being at the bottom as well; I look forward to seeing those options in future releases as well.
[Nook Color General] rogerdugans:
It does get confusing....

Yes, the dev who took on the project has frozen the features now- nothing new will be added.

He is trying to address the current bug list and once that is complete it should be merged into the ROM and a part of the regular nightlies/release candidates.

One of the things I like most about what Mad-Murdock has done is that everything is configurable: what you want, where you want it.

Nothing at all wrong with waiting and sticking with the regular nightlies, of course, but if you like the look:

everything used in the nightlies is used in his test-releases when he builds them.

He syncs up his local version of the source repository and compiles then uploads it for us.

For a while I was tracking nightlies too, but at this point I don't like not having my Tweaks. ;)
[Nook Color General] LarcenQ:
Yeah I read through the entire thread after you offered up the link, thank you.

So what you're telling me, and forgive me for probably re-re-clarifying, but until his work is merged into the trunk, or whatever repository they use, I can simply use the build from his thread?

AND for further clarification I don't need to format anything, I just 'install from zip' right over top of my current install? I finally got everything laid out how I like it (apps, widgets, etc) and I would hate to have to start over. :P

Thanks much again!

Signed,

On the right track.
[Nook Color General] rogerdugans:
No problem.

That is correct: use this instead of nightlies.

Flash exactly like a nightly- I use rom manager- and I have not yet had to wipe anything when doing nightlies or the tweaks version. Your mileage may vary, as they say, but I have had no problems at all. And not read of many either.

No problem, man. I do little around here except find out things for my own benefit and gain roms to use on my stuff, so helping others do the same thing helps me pay back those who helped me out.

The one thing I DO add is the overclock kernel. That is flashed from rom manager the same way AFTER you install the rom. Search for dalingrin's oc kernel if you want to try it.

Wait- there is actually one other thing I do on a regular basis:

Using rom manager I do a backup maually when everything is running well. That way I can name it something that makes sense to ME ("CM7_tweaks_oc_04_01_11" for example) in case something does break.
[Nook Color General] LarcenQ:
Awesome, thanks again. Though I've never touched the 'rom manager' I normally use the ClockWorkMod on a SD card I keep just for updates & backups. I'll give that a look tonight after work.

Now if I can just get Handbrake and Nook to play nice together we'll be in business.

If I encode a test file (roughly 5 minutes worth of footage) it plays just as nice and smooth with excellent quality @ approx 75 - 90mb. However, using the EXACT same settings I encode the entire movie, it still looks nice on my PC however when I push it to my nook, it will not play open, as if permissions were bad. If I set permissions (IE: adb shell chmod 777 /path/to/file/file.m4v) it doesn't fix my problem. Another possible issue I thought was maybe the file size (roughly 3.5gb), but haven't found any posts anywhere where file size is an issue.

Anyway! I'll keep plugging away at that until I get that taken care of as well. :)
[Nook Color General] sorheim:
Using MadMurdock's version of CM7 with the built-in tablet tweaks and it is near perfect for my expectations of this device.
[Nook Color General] xdabr:
So is mad_murdock's build available for SD card and/or usable with the "size agnostic SD card" technique?
[Nook Color General] al2x:
Quoted for truth. I've never used anything as seemless as this ROM. Gives me near-exact quality of gingerbread 2.3 that my Incredible has gotten a while back from CM7 as well. The bottom status bar is truly one of the most needed things for the nook. I'm not huge into the tablet game yet, I really bought it just to **** around a bit with the hacks, play some apps/games on the big screen, and most importantly aid me in school a little bit, I've been basically reading all my text books on this nice compact nook.
[Nook Color General] pmilford:
Bet it will work if you limit file length to less than 2GB! (Have you tried a

different movie player on the 3.5GB file on the Nook too?)

Peter
[Nook Color General] LarcenQ:
Hrm, 2gb you think? Anyway! I tried rockplayer, flikie, and whatever the defauly player is that came with CM7. I'll have to do some more playing around tonight to test that 2gb theory.
[Nook Color General] envygreen:
I believe (and someone correct me if I'm wrong) you can flash in this order:

Nightly CM7

Tablet Tweaks

Dalingren's OC Kernel

However, if the nightly CM7 is the same as what the last MadMurdock Tablet Tweaks build was based on, you can skip the first step. When new version come out, yeah, you just flash them over your existing build and get new features with no customization lost.

RE: Handbrake and CM7 Nook

I got pretty good at encoding for the rooted nook based on the settings you can find here and at androidtablets.net, but I wasn't sure if the native size or anything else changes in CM7 vs 2.1 rooted. If anyone knows, speak up! Otherwise, I'll post once I find something definitive.

EDIT: OK, rooted, I was using 720 width and CM7 = 848 according to a couple of threads

However, I wanted to mention that if you do two pass encoding (with turbo first pass) and go for a target size, I got pretty excellent video at around 500-750 megs per hour. The two pass really helps on action movies imho.

I think my only outstanding issues at this point are 1 - Some apps want to run in cell phone size. Google Reader, I'm looking at you. (Newsrob was a good alternative I found though) 2 - When apps force full screen, they currently overwrite the tablet tweaks bar and the handy included keys.
[Nook Color General] xdabr:
I can't seem to find anything definitive -- most seem to say that Android only supports a maximum video file size of 2 GB (regardless of file system?).

But Android 2.2 may only support 512 MB ?

http://stackoverflow.com/questions/5217744/is-there-a-file-size-limit-on-android-honeycomb

And the FAT32 file system under Android only supports 2 GB files....

Anyway, you can always break it up into smaller chunks.
[Nook Color General] LarcenQ:
Thanks again, both of you for the info. I'm betting it is the 2gb file size then. Darn it, gonna have to work on that, I hate sacrificing quality for file size! :/

The route to patch using table tweaks makes perfect sense. I keep forgetting that in the end, Android is ultimately just a Linux flavor customized for phones/tablets/etc.
[Nook Color General] envygreen:
Aside from something realllly dark with lots of fast motion where the video quality can really make or break the experience, I haven't any complaints at all. 750 megs per hour looks like 98% of the quality I'd expect from a DVD, at least on the nook screen size!

My handbrake settings for reference (and so others can tell me if they have a better setup!)

Select Regular/High Profile

Picture Tab

Anamorphic = None

Check Keep Aspect Ratio

Set Width to 848 (or 720 if source is lower than that) and height will auto correct

Video Filters Tab

Set everything to off

Video Tab

Video Codec = H.264

FPS = Same as source for DVD or 29.97 otherwise

Quality = Target Size and put 750 megs per hour. (500 for movies without action is more than acceptable usually)

Check 2-Pass Encoding

Check Turbo first pass

Audio Tab

Delete any extra tracks and keep only the AAC (faac) track

Audio Codec = AAC (faac)

Mixdown = Stereo

Samplerate = 44.1 (Can't tell the difference between it and 48 on the Nook)

Bitrate = 96 or 128 (Ditto 160 BR)

DRC = Cranked to your preference. (I like 3.5 out of 4 max)

Skip Subtitles and Chapters tabs

Advanced Tab

Maximum B-Frames = 0

Uncheck CABAC, 8x8 Transform, and Weighted P-Frames

Heh, finally found the thread I was thinking of where I discovered all of that. All of it is standard except I played around with the video tab because I didn't like the crazy variations in file sizes I got with constant quality and average bitrate sometimes struggled with action scenes.

[Nook Color General] LarcenQ:
LoL That is the exact thread I used to get where I am right now, except for the 750mb/hr. Perhaps I should have read past the first page of the thread to make sure I was on the right track. Thank you, I'll give these adjustments a run tonight on some lame movies (Pulp Fiction, The Wall) and then on something worthwhile (Transformers, A-Team, etc).

Signed,

Stay tuned. Same Bat-channel, same Bat-time.
[Nook Color General] joelszs:
As much as I love Transformers (the new movies are AWFUL - the 80's animated was the bomb!), I certainly hope there's serious sarcasm intended when calling Pulp Fiction and The Wall lame! :)

Update - I am running the latest version of Phiremod on my emmc and loving it! That's right, the training wheels are off and my SD is no longer my booting option of choice.

Overclocking to 1100 is cool - perhaps it's a placebo effect, but I see a massive boost in snappiness in both browser function and overall UI smooth-ness.

I am continuously amazed by the community around this device and Android in general. Coming from the iPhone community, I've learned so much more about coding and computer science in the last month than I ever expected to. As a biology grad student, I really appreciate the thorough work being done to fully utilize the nook and most importantly, how helpful everyone is!
[Nook Color General] LarcenQ:
It was sarcasm actually, they are two of my favorite movies. AS is the original Transformers (Movie, and shows, G1 of course.) and other than a few mistakes, the new A-team isn't so bad. Anyway, that's neither here nor there!

Update: I encoded a movie last night, per the settings given, using the 750mb/hr and it came to around 1.5gb file size. Played (yay!), looked good (quality wise) and sounded OK, kind of distorted, could of been my headphones though. However, usually every 15 - 30 - 45 seconds there is a hiccup with playback. Its almost like you hit pause for just a millisecond. Maybe its just a performance issue, I didn't have time to watch it on the PC to compare, but for now that's what I'm hanging it on. If I'm out on the road, traveling, and not driving and have a need to watch a movie I'll never complain. It would be annoying, but considering the alternative (no movie, watching cars go by, etc) I can handle that.

Oh! And as for overclocking, maybe its just me, or maybe I was expecting more, but I don't see that big of change from 800Mhz to 1100Mhz. Maybe a slight performance increase, some lag still at times when in landscape mode. That may be cause I'm using ADW Launcher EX though? Anyway..

I did however remove Phone.apk, TelephonyProvider.apk and Mms.apk and that got rid of the 'cell standby' that was eating away at my batter, but I still have the 'phone idle' showing up. I'm thinking that doesn't go away, just the 'cell standby'.
[Nook Color General] Gin1212:
Set your governor to "Interactive" and the Minimum CPU to either 800mhz or 1000mhz.
[Nook Color General] LarcenQ:
Hrm. I wasn't sure 100% how all those settings worked, I'll give that a try tonight after work. Thanks!
[Nook Color General] envygreen:
Interactive Governor will help a lot I think. Might not even have to bump your min processor level, just make sure max is 1100.

Video playback was perfect on my rooted nook, so this may be one area where they are still ironing out the hardware accel in CM7? Not sure. Been too busy to mess with transferring my movies to the SD boot of CM7 and test playback. What are you using to play the vids? I was using Doubletwist for the record.

I replaced my launcher with Zeam a while back and can't give it up. Sadly, it's no longer in active developent, so sooner or later Android is going to leave it behind and it will break and I will cry, but for now, it's lightweight, simple, and fits my needs perfectly.
[Nook Color General] poofyhairguy:
I have encoded tons of movies for my Nook and that is what happens when the bitrate is just SLIGHTLY too high.
[Nook Color General] LarcenQ:
Thanks Gin1212 and EnvyGreen, I'll give both of those suggestions a run tonight after work, hopefully it'll have me rethinking my previous comments.

That's what I was figuring too; I've encoded tons of movies in my lifetime as well, none for the nook until now however, and that's usually the result. That, or drop in bandwidth streaming from my media server. Anyway! If adjusting the CPU performance doesn't correct this issue, then I'll have to keep tinkering until I find the sweet spot to rid my encodes of this issue.

By the way, poofyhairguy, what settings do you use in Handbrake (if you use it) to encode your movies? Do you use the same except set a CBR rather than static file size?
[Nook Color General] poofyhairguy:
I use a Constant Quality of 22.

If the source is 24p I leave the framerate alone, otherwise I change it to 29.9999.

I use Anamorphic Loose, and I make sure the width value is under 852.

I also crank the DRC to 3.75 under audio to make up for the Nook's speaker.

Here are another user's Handbrake setting recommendations:

[Nook Color General] polarborn:
Video encoding

I also have tons of movies I encoded for the Nook. I'm using Format Factory also free, and the basic MP4 high quality setting. If the file size is still too big, I jusr re-encode it using the MP4 medium setting. No muss, no fuss. Great video and audio is always synced.
[Nook Color General] LarcenQ:
Thanks for all the suggestions!

I have a question about performance. I see all these people talking about quadrant scores, so I installed the app. With 'Interactive' and 800min/1100 max clocks I got a score of ~1100. Setting the 'Performance' governor and 1100/1100 clocks gave me a score of 2012. Does that sound reasonable in comparison to everyone Else's performance? The only time I experience any real 'lag' is on my app drawer screen, which is probably due to the column/rows setup in ADW Ex.

And as for encoded movies, I'm thinking my problem with the hiccups were from the source media being Bluray. That or each movie differs from what works, and what doesn't. Meaning there is no turn-key operation.
[Nook Color General] envygreen:
running tablet tweaks RC1 version of CM7 from a class 6 SD card with Dalingrens OC kernel - Interactive, 1100 max 300 min

Got 1649

Switched to Performance governor

Got 1882

Been meaning to try the SD card performance tweak, but been a busy week. Wonder how much (if any) difference it would make.
[Nook Color General] LarcenQ:
Thanks. I wonder how much of a difference running on internal memory vS SDCard makes.

Anyway, after tons of tweaking and multiple re-encodes of movies I've come to the conclusion it has to be only that the bit-rate used is causing the very, very, VERY minute stutter at random intervals. Sound is good, picture quality is good, and since my 'score' is slightly higher than yours, it has to be in the bit-rate.

I think once CM7 goes 'stable' I'll do a full wipe and start over, cause at times my display lags going from side to side, or into programs like the app drawer. I probably have my ADW Ex columns/rows buggered up or some other settings.
[Nook Color General] jhitesma:
I really liked ADW but ended up switching to Launcher Pro specifically because of how much smoother/quicker the app drawer in LP is. Apparently ADW doesn't use hardware acceleration while LP does according to some of the posts I've read on here.
[Nook Color General] mcb01:
If I boot to CM7 from an SD card, is returning to rooted stock as simple as just booting back up without the SD card inserted? If I understand correctly, booting from the card should leave the internal memory untouched, correct?
[Nook Color General] LarcenQ:
Yes. Nook looks at the SDcard first before booting to the internal partitions. (YAY!)

Update on Movies..

So, setting a CBR of 1100 gets the job done. SD (standard def) movies are for the most part perfect. Clean lines, no stutter (at least in the 2 I test drove), though on occasion there were pixelation in the darker areas of the film (Blacks and dark colors mostly). This pixelation occurs a little more often and worse from Bluray sources as is there the occasional stutter, though not as bad or frequent as before. None of which are deal breakers, just saying. I'm anal when it comes to audio/video quality when encoding.
[Nook Color General] envygreen:
Thanks for the update LarcenQ, I'll try that out on my next batch!
