[HOWTO] Speed Fix! (variant of mimocan fix)

This is a quick walkthrough of how to apply my variant of "Mimicans speedfix" using my kernels on the Captivate. The speedfix essentially consists of making an ext3 or ext4 filesystem on an sdcard, and using that as our /data directory. This method is different from the original method in many of the details, but the underlying basis is that the stock /data partition is slow as molasses so we replace it.
This method should be pretty safe. As you will notice we dont copy around stuff and create a symlink mess. We just mount a partition over the current one. Yes we still mount the old one as well, even though it wont be used unless you take your card out. If that happens the phone will mount your old /data (that will probably be very out of date at the time) but itll get you up and running right away.
Right now there are two kernels, these mount the default partition, ext3 or ext4 on the second sdcard partition, the two options are:
Stock clock speed and Overclocked.
The overclocked kernel will clock from 100 to 800 Mhz as stock, then skippinig 1Ghz going to 1.2 Ghz.
Also, before we begin make sure you have this version of Odin. I used Samsung windows drivers that I found here.
You'll also want to read this thread about download mode. here you'll learn that you will have to try real hard to actually brick these phones, and even then it may still boot.
Ofcourse you also want to have root on your captivate.
You'll also need the android sdk.
If you are on Windows or Mac you will need some software to partition and format the sdcard, this live cd will work. You could also just get an ubuntu live cd or similar.
So, now we have the necessary tools and our new kernels and can get started.
Partition the disk:
There were reports from the modaco forums when mimocan first released his fix that ext3/4 partitions larger than 2gb were a problem, so keep your 2nd partition 2gb or smaller.
Use your favorite partitioning sofware to create 2 partitions on your sdcard. the first one will be formated FAT32 (vfat), and the second one ext3 or ext4. Make sure both are 'primary partitions'. You may want to make the second partition have partition type 83 (linux native).
Copy data files to sdcard:
If you are coming from stock, (eg without an existing a2sd /data partition on your sdcard) boot the phone without your formatted card and hotplug it before starting this process.
Using the sdk you need to connect the phone and use 'adb shell' to get a prompt on the phone.
Then follow these steps:
Code:
$
$ su -
# mkdir /sdcard/mnt
# mount -t ext4 /dev/block/mmcblk1p2 /sdcard/mnt
# busybox cp -a /data/* /sdcard/mnt
# umount /sdcard/mnt
# exit
$ exit
Flashing the kernel
1) Disconnect USB cable.
2) Open up odin.
3) Put your phone into download mode.
4) Connect USB cable, wait a second Odin should detect your phone, if not fiddle about with your drivers and reboot windows or something. This can be a real PITA.
5) In Odin load the kernel tarfile as "CSC"
6) Click "Start" in Odin, flashing should only take a few seconds.
You may run into issues here randomly and have a phone with the phone-!-computer image (I did!). Just go read up on the 'download mode' thread linked above it tells you how to proceed.
7) When you have booted your new kernel and /data partition you may have some issues with a few widgets/apps. Reinstalling or waiting/fiddeling with them seems to solve the issue. Maps was slow to open the first time after a new /data partition was mounted for me a few times, but subsequent launches were snappy.
If you want you may donate to my beer fund. It is not necessary but much appreciated

Didn't work for me. I partitioned my external SD card, flashed the speedup2 kernel, then ran the commands you posted, replacing 'ext3' with 'ext4'. My quadrant score is still in the low 900's.
Can you explain exactly what those commands do? The mimocan fix makes a lot more sense to me. Why did you decide to take a different approach?
Thanks for your help and effort!

I get 1716 scores in quadrant, but with real world running tests Touchdown and Dolphin HD browser still lag like holy hell.
I originally had the "method 2" hack (moving apps to the NAND) and that worked wonders, especially with these apps.
Can anyone test these two applications and see if there is lag for you?
Dolphin - try opening a new tab, closing it, and goto a large page and scroll with the volume buttons - it should all be smooth and quick
Touchdown - It should be very quick going between emails, I get a 5+ second delay before showing the email
Also in Quadrant, even though I get 1700 scores, do you guys get stuck at I/O Database writes for a good 3+ minutes?

The captivate speedup kernel link is dead. Can soneone please post a mirror? Thanks

Worked great for me using ext4 partition/kernel. It brought my quadrant to 1817! Thats with a poor little 4gig, class 2 micro sd card. Im also running the i9000 JM2 firmware with Samset 1.6.
Thank you for all your hard work!!!! My phone is now complete (for now lol).

All you do is copy the files from your original /data partition onto the root of your ext{3|4} partition on the sdcard. Then that is mounted on reboot ontop of /data so you can use the new data partition from your card.
I feel this is a MUCH cleaner method than the original Mimocan fix, that copis a full copy of data into the root of the device (unnecessary backup since you still have your original /data partition as well), then it mounts your sdcard on /disk and symlinks that to /data.
I just don't see the need for the symlinks and stuff and honestly I thought this was a simpler method, no symlinks or anything.
If you arent seeing any speedups I'm betting something didn't go right, you are probably still running of the old /data partition. Are you sure you are running the speedup2 kernel and not the ext4 only kernel?

yeah database I/O takes forever still.
Like I said in the other thread, try to reinstall the apps, Dolphin is very very fast here (thanks for getting me a new browser btw.)

I'm still a complete failure and now i get stuck at the galaxy s boot screen

Nuke, after doing the ext4 only method, I only get quadrant scores of 900.
Am I doing something wrong? I go through all the steps fine and everything seems like it went well but it seems like I'm doing something wrong down the line.
one thing I do notice is that I have A LOT MORE AVAILABLE MEMORY in advanced task killer. I use to only have 100 now I have 180MB.
Is it crucial to have to flash the Speedfix2?

after i put in
busybox cp -a /data/*
nothing happens it just sits there

What do you mean by "there is no trailing dot" ? Did you type it in? You need to include the trailing dot in your command; based on what you posted it appears you did not do that.

WOW! Okay... So now I'm getting 1756...
You just have to leave Quadrant on for like 15 minutes sometimes! This is very strange!

Notice the period after the asterisk. In the old forum, someone had a problem with that.
I did this fix last night after countless times of my messing up and figuring out how to partition with my phone still being able to read the card, flash problems with Odin, etc etc. I'm using an 8gb Classic 6 and just got an 1805 in Quadrant, and the phone is incredibly, noticeably faster. Did have some weird app problems when it was first applied, but some reinstalls fixed it. Thanks again Nuka!

FroYo Freezes fix

Use with 2.0.54 only, root is not yet available with 2.0.71
disclaimer: swap IS evil, you don't want it! Swap is a dirty workaround for crappy hardware (well somekind of) ... Don't complain if you put a swapfile on your internal memory (the 8 or 16GB flash disk) and it will stop working. Swap read and write like hell, so if you want to try it, please use an external disk, like usb, or better: micro SD. And of course i'm not responsible for anything ...
a) download http://hitme.resetbutton.de/priv/swapfiles.zip
b) unzip it somewhere on your PC
c) pick what you want ... i prepared a 128, 256 and 512MB swapfile in it. It might be smart to start with 256MB
d1) connect to your PC and use the dropdown area (on the Archos notification bar) to enable file transfers
d2) on my system the sd card is mounted on windows as "removable disk" .. the internal is A101IT, so if you have a sd card use "removable disk"
d3) transfer the file (the size you want, or all) to your Archos device, as i said: internal memory might be a bad idea, use a sd card
d4) on a windows system use the "safe remove hardware" or whatever it's called and unmount the disk form the archos. After that, on the archos at the orange Android screen: click the button
e) use z4root to root your device temporarily ( you can find it here: http://forum.xda-developers.com/showthread.php?t=833953 or google for z4root)
f) use the first option in z4root! a permanent root will not work (at the moment). If it's not working: enable USB debugging AND connect it to a PC
g) download a terminal if you haven't so far. Search in the market for "terminal emulator"
h) start the terminal and enter: su
at the first time you will get a request that you really want it. If you don't get it: root didn't work, happens sometimes. Power off your device and try again at e)
i) locate where you put your swapfile ... it should be /mnt/storage/sdcard, or if you don't have a sd card: /mnt/storage
j) go into the directory by typing: cd /mnt/storage/sdcard ... or cd /mnt/storage (without a sdcard)
you can list the content of the directory with: ls
k) type: swapon swap256
or the file you copied (swap128, swap256, swap512)
l) type: free
you should now see that you have swap memory
m) report back which file works best for you!
This will now work until you reboot your device. If you do: start again at e) .. of course you don't have to download z4root or the terminal again, so it's:
root with z4root
start terminal and enter su
goto the directory where the swapfile is (cd something)
swapon swap256 ( or whatever you used)
control with: free
done
WARNING: if you use a swapfile, which is described here, you can't use a usb connection to copy files without doing this:
start the terminal, enter: su
go to the directory where the file is ( cd /mnt/storage/sdcard or /mnt/storage) and do:
swapoff swap256 (or whatever you used)
This mini howto is for a swapFILE ... the advantage is that you don't have to make new partitions on your sdcard, but it might be a little bit slower than a swapPARTITION. If i have more time i will wikify this and extend it with the partition part ...
Credits go to http://forum.archosfans.com/viewtopic.php?f=74&t=42718

Is there any way to make that into a script that can be run during boot?
Also - you can download terminal emulator from Archos Aps and no root required.

impossible without perm root (we cannot modify root fs, so no chance for boot scripts...)
wait for SDE and custom roms

You can only use this while temp rooted (to use the command swapon), also, there should be NO reason why you should be rebooting anyway...

I tried this successfully in my Archos 101 but using the Internal Storage, not the SD card itself. I ran it for 3 hours straight opening very heavy stuff. It solves the stability issue, now my 101 doesn't hang when I open too much stuff.
My only concern is that the swap file operation may shorten the lifespan of the media because such media usually has a finite number or write operation cycles to it.

Just enabled a swap512 on a spare sdcard i had. Initial impressions is... WOW this thing flies! Apps are just popping open now with no lag and flicking screen to screen is almost instant. Will report back on the stability after I've had a chance to play with it but THANK YOU OP!!

Use a fairly good MicroSD card with it, high read/write cycles on it. It will last longer then.

Wow this worked great. My system is flying.
A put the 512 on an 8gb sd card.
I opened dolphin with 8 tabs, angry birds seasons paused after playing no problem. Then opened regular angry birds and played that with all others still running. No issue.
I also have music playing in the background.
I opened the my piano ap and played that with all others in the background.
Works just perfectly.
Here are my memory stats under free
used: 242148 free 2604
swap
used: 143652 free 380628

I'm going to try this too... once I got the archos rooted again... z4root isn't very reliable to be honest. Currently it's not working 90% of the time. But that's another issue in another thread.

Working fine too... I'm using launcher pro, started some apps, played angry birds seasons and yet no freeze.
Firefox beta was unusable without swap, now working like a charme. I'm checkin on Dolphin HD next.

Works great, put a 512swap on my 8 gb micro sd and no freezes anymore

Really Fix Freeze problem, it look smooth now...

Thank you very much. I will try on my Archos 101IT

This will not work with the newest firmware as temp root no longer works. However, the improved CPU and memory management should compensate for that.

[Dev] Native linux on Iconia

So, let's get linux installed natively on our Iconia.
As some of you I have been working on porting Iconia to chromeos 2.6.38 kernel (to get rid of Acer crappy moron-written drivers (well.. nothing personal, but most code written for commercial embedded devices is a pile of crap and you have to rewrite everything to update kernel or integrate upstream))
For now, I have hardcoded the kernel command line in the boot config to boot off /dev/mmcblk1p2 (that is, you must create ext4 (this is also hardcoded.. uhh)) second primary partition on your sd card with the root fs). For now, until all hardware is working fine and userland is ready, let's boot off micro sd. We don't have nvflash yet so let's leave repartitioning internal storage aside.
Flash the kernel image instead of boot.img to LNX or instead of recovery to SOS. And make sure to write your UID in a secure place before messing with the device - this is the only way to flash your device if you have checksum errors (you should contact sc2k in that case). Okay, even if you eff up here, there is still a way to get UID from a brick so take it easy. But if you do screw it, be prepared to work hard and use some command-line tools.
You should be able to use any armel rootfs. For X11, use fbdev driver and evdev for touchscreen.
For the proprietary NVIDIA accellerated drivers for X11, OpenGL ES and OpenMAX, download the nvidia-tegra package from AC100 PPA https://launchpad.net/~ac100/+archive/ppa (probably you have to manually download using this link http://ppa.launchpad.net/ac100/ppa/...dia-tegra_12-0ubuntu1~alpha1monson6_armel.deb as the package didn't show in aptitude for me after adding to sources.list.. or i was doing sth wrong) or the tarball from nvidia. A newer package of tegra drivers is available at https://launchpad.net/ubuntu/+source/nvidia-graphics-drivers-tegra. You may just add an alternative to mesa EGL/GLES library path via update-alternatives to always use nvidia libs.

Here is some video
http://www.youtube.com/watch?v=NlGHZ5VTAr8
And now - we need developers, developers, developers.
The git is https://github.com/astarasikov/iconia-gnu-kernel
The main branch is chromeos-2.6.38 that is more stable. The 3.0 branch is unstable (network traffic causes virtual memory trashing).
For now, the following stuff works
-Panel/framebuffer/backlight
-Touchscreen
-Internal eMMC
-microSD slot
-usb gadget
-usb host
-gpio keys/buttons [rotation switch acts as wifi/bluetooth power blocker. iirc, left position disables wireless, right - enables]
-charger
-battery
-shutdown
-LEDs
-bcm4329 wifi (don't forget to copy bcm4329-fullmac-4.bin to /lib/firmware/brcm and nvram.txt from android's /system/etc to the same dir as bcm4329-fullmac-4.txt) [causes lockups with 3.0 kernel]
-nct1008 temperature sensor for cpu throttling
-sound. external speakers and headphones.
-bcm4329 bluetooth. accessible at 115200 on /dev/ttyHS2. Look at http://htc-linux.org/wiki/index.php?title=Ubuntu/Leo/Bluetooth to get it running at higher speeds with proprietary firmware patches (hcd files from android)
-suspend. Although will probably drain a bit more power than android because mmc power is not disabled (due to a race condition in kernel. and because we have rootfs on micro sd). Two glitches are: sometimes, the device freezes for several seconds after suspend (will test later if playing with wifi clock fixes it) and fonts get corrupted after suspend if using proprietary nvidia X11 driver. [suspend works in 2.6.38 only]
-kxtf9 accelerometer
-mpu3050 gyroscope
-ak8975 magnetometer
The following stuff is broken or not implemented at all
-hdmi video. May be working but no one has tested. hdmi audio is not implemented.
-light sensor
-video cameras, focus, torch.
-gps. To turn on the chip, it should be enough to enable gpio 203 via sysfs. Unfortunately it uses the proprietary MEIF protocol which can probably be obtained from Nokia under NDA. And I don't feel like disassembling the whole megabyte of the gps daemon
-3G. I don't have the modem in my iconia. So I don't care. But should be easy to add.
And one notice for those who want to join in. I don't care if hardware works properly. I want 'beautiful' code. That is, please, when you make patches to add functionality, do not follow the path of corporate coders and do not invent custom interfaces and sysfs hacks. Use rfkill for bt/3g power control, for example. And don't be selfish - please share your patches and userland stuff.
TODO:
-fix framebuffer issues (no console till X boots, X fonts and window decorations get corrupted after suspend with proprietary drivers) it kinda works.
-video camera
-port meego or build the list of good software in ubuntu for handling sensors, virtual keyboard etc
I'm not currently working on the project and don't have the device anymore. Feel free to PM me if you need help with some tegra hackery

good job...

I see no reason why not. But you'd have to hardcode the uuid of the boot partition in kernel command line or build a ram disk. Anyway having to use a heavy and power consuming external storage sounds like an extremely stupid and useless idea

I would like to try with different kernels but I'm still not confident on how to do this.
If I use dd if=zImage of=/dev/mmcblk00p1
will this effectively boot this kernel after pressing power and vol- keys ?

No.. You need to build boot image with android's mkbootimg and flash instead of recovery. And then, mkfs.ext4 on your sd card on partition mmcblk1p2 and untar rootfs there

Thanks man, this is really getting clear to me now.
I'm going to try and post results here. I will love to try and see how arch, fedora and ubuntu will run on A500.

There are two apps in the Android market that will install either Ubuntu or Backtrack for you- they are not native installs though I can confirm they perform well even if it is chroot and I can also confirm they work on the iconia great!

[Q] Re-sizing Partitions

I use my Nook Touch for reading only. I do not need it to access the internet or download apps. From my understanding, these are the main reasons to root one's Nook.
What I am interested in is gaining access to that 1.5 GB or so of internal memory. As the majority of my books are side loaded, it makes much more sense to have 1.5 GB available to me and only 240 MB for B&N downloadable content.
My first question is, if I am going to try to re-size some partitions and I have no interest in apps, which rooter is the simplest for v1.1? SalsichaNooter or TouchNooter?
And finally, I have searched the forum and there are a couple of threads about re-sizing partitions, but they all involve linux terminal work. I think I might be able to figure it out, but could a linux disk partition program (like gparted) be used instead?

Ok, I found a thread posted by ros87 here that details how to go about resizing the partitions. It was very helpful, however, after rebooting back into my Nook, I am no longer able to connect to the internet.
I am not sure if either the sdb6, sdb7, or sdb8 partitions have any connection to wireless internet, but I noticed during the step of:
#mount /dev/sdb8 tmpdata
Click to expand...
Click to collapse
I got some socket warnings relating to a wireless file. ros87 says to ignore the socket warnings, which I did. Then at this step:
#tar xf tmpdata.tar tmpdata
Click to expand...
Click to collapse
I got a whole bunch of errors about unable to write files. But when I checked the drive, it seemed that all the folders copied over okay, so I continued on through the steps.
I probably should have copied the error output, but after discovering that wireless isn't working (it says "Unable to Connect"), I'm thinking maybe something didn't copy over correctly.
Should I try deleting and copying over the tmpdata.tar again?

Go trough dmesg and logcat (in adb shell) to see if you can find any troubles about your wifi connectivity, then post it here, but not the complete logs please!
As for my posted setup, I ran it for several weeks, with wifi enabled, without any troubles at all.
The socket errors is not the problem. A socket cannot be copied, and it is recreated whenever the socket service is started.
-R

Can I use adb if my Nook isn't rooted? As in, would I be fine just using noogie? I won't be able to try this until I get home.
Edit: Found this. I'm not interested in apps and such, so this seems the best option for me. Will post the dmesg and logcat later.

Okay, so I restored my backup image and checked the wi-fi. That is coming up as "Unsuccessfull", too. So maybe the problem is my wifi setup? My ipod connects fine, so I'm not sure what the problem is.
Just for future knowledge, is it safe to erase and de-register the device with different sized partitions?

[Q] Running CM7.2 (MiRaGe-KANG build) - How do you know V6 is working? Wi-Fi Question

Hi All,
I'm new here but have been reading the threads since I got a Nook Color last month.
I'm booting from a 16GB microSD card: [CM7.2-RC0] MiRaGe - KANG build of CyanogenMod ("encore_CM72-MiRaGe-12122011") and also installed "gapps-gb-20110828-signed"
I ran the Battery Calibration tool just yesterday when it was plugged in and at 100%
I installed the Nook Color USB Mass Storage utility so that I could access the SD card from my computer
I also followed the thread's advice on installing V6 Supercharger (http://forum.xda-developers.com/showthread.php?t=1344873):
Nook Color with its large kernel with many features consumes the RAM rapidly and low memory becomes an issue where V6 Supercharger becomes useful.
Here is how I install, it takes only one minute.
- Download update 8 to sdcard root directory.
- Start Terminal Emulator and do the followings
- su
- cd /sdcard
- sh V6*
- choose option 0 (fastest scroll)
- choose 9
- choose option 16 to reboot ​
I have a couple questions that I can't ask in the dev threads since I just registered here.
How do you check if V6 Supercharger is working? I didn't install BusyBox or Script Manager like the original V6 Supercharger thread suggested...so is there a way to do this through the Terminal Emulator?
What do you recommend overclocking your CPU settings in CyanogenMod settings to? I have mine currently set to Conservative, Min: 300 MHz, Max: 1100 MHz, and Set on boot. Would 1200 MHz be pushing it too much?
I've read some questions and threads on here regarding the Wi-Fi turning off when it goes to sleep. When you press the side power button to turn off the screen, is that also putting the device to sleep? Is there a solution to the problem of the Wi-Fi turning off on its own when the screen is off?
Thanks in advance to any advice or answers! And of course, if you have any suggestions on other things I should be installing/uninstalling I'd greatly appreciate it!

1. Open your app drawer, flick the screen, if it scrolls instead of stuttering then V6 is working.
2. OC as much or as little as you want. 1200 is safe but some people say that the increased battery drain isn't worth the slight increase in speed. You have to decide for yourself.
3. Yes, that is putting the device to sleep, yes, that will turn off your wifi. Most people prefer sleep to just screen off because it saves your battery. The old CM7.0.3 and earlier didn't have sleep mode and you lost 1-3% of battery per hour of standby. If you're ok with that then:
wireless & network settings > wi-fi settings > menu > advanced > wi-fi sleep policy>never

Thanks a bunch! I was wondering why there wasn't an "Advanced" option when I went to Wi-Fi settings...didn't even think to press the menu button! I chose to set the sleep policy to "Never when plugged in" and we'll see if that works for me. Is the default "When screen turns off"?

yup, it's been the default on every android device i've used. It allows you to put your device to sleep and then turn it back on when you need it without having to wait for android to boot. I can tell when an app kept my nook from sleeping because my battery is dead.

I installed the Nook Color USB Mass Storage utility so that I could access the SD card from my computer

I don't think you (we) need this step since I believe the feature has been integrated into the latest CM7 builds, assuming MiRaGe the same.

Without even installing V6 Supercharger, I don't believe that I ever experience the stuttering. If that's the case, how do I know the V6 script is working/running/better performance?

You can tell it's installed Ok by running it again and using option 1 to show the status.
Not so easy to tell its immediate benefit as its real job is trying to ensure that the memory is kept free, so you have to compare operation over time as more apps get used / loaded.

You know, I'm not sure if I ever experienced the stuttering either. I'll have to check later today.
If I just used the Terminal Emulator, would I essentially do these steps?
- su
- cd /sdcard
- sh V6*
- choose option 0 (fastest scroll)
- choose 1 (to show status)
- choose option 16 to reboot
Also, just want to confirm that you need to keep the V6 file in the sdcard root directory right? I'm assuming if you ever delete or move the V6 file, V6 Supercharger would stop working?

By definition, "root directory" of the bootable CM7 uSD card is the one that has 117MB where ROM/GApp zip files used to be. If that, I don't believe that we (or NC) can access that partition. If it does, I want to know too.
With CM7 runs off eMMC, root directory of "normal" uSD card is ......... ehh, not in any sub-folder.
Can someone who actually do run V6 script chip in for some info?
Big thanks

Oh I'm sorry, when I wrote "sdcard root directory", I mean the root directory of what you can access when you plug it in via USB and not the partition where you're booting CM7 from. It's essentially where I save all my folders of wallpapers/music/videos/etc.

Oh, ok.
Did you run the script yet? How was it?

No offense to the person that suggested checking V6 by flicking the app drawer, but there are a couple more reliable options.
I am no expert, by any means, but from looking over the program, it looks like all it really does is prioritize your apps by whether they are foreground or back, a launcher or hidden and so on, then allocate memory to the apps following that priority. I think any response check would wholly depend on how many apps you have running (or being killed by the V6 task killer)
Either way, even if it turns out that I wholly misunderstood the program, I can tell you how to see if it is installed and running for sure.
This will work if you have already installed the V6 or not. the following are directions for terminals, if you are running the dev's Scripter app, I would imagine it is similar, if not automatic.
Open a terminal.
su
cd sdcard/
sh V6*
the menu then scrolls. option 0 is often recommended here, but that is just a value for the scrolling speed of theV6 script itself. you can increase this number if you errant to spend a little time looking over what you're running.
f you think you have already ran the V6 look below the 17 options to current minfrees. If you want option 9 (Mirage Kang's recommendation) the current minfrees should read 6, 12, 75,100,125,150 mb. if it does, then you are supercharged. if not, go ahead and select option 9.
Now before you reboot, I would recommend that you run option 15 if you are not using Scripter. that will run V6 through the terminal emulator. That way, should you ever want to check your values or mess with the options, you can open terminal, su, then bash V6, and it will run.
Even if you don't think you will ever want to readjust the supercharger again, it had the added benefit of yelling you your "installation was INCREDIBLY SUCCESSFUL" which is bound to make you feel supercharged.
Run option 16 to reboot and now you can feel secure, without relying on a subjective flick of the app drawer.

Thanks everyone! I'm going to try uninstalling the USB Mass Storage app I downloaded then, if I don't actually need it with the CM7.2 version.
I did run Terminal Emulator to see what the minfrees were and it was the same as option 9. I didn't even think of running option 15, but I've done so now. After I rebooted, I opened up the Terminal Emulator again and typed "su" and then "bash V6" and it says "bash: V6: No such file or directory". Am I doing something incredibly stupid or wrong?
Also, do I have to leave the V6 txt file on the sdcard or can you delete it after you've run it?

I would bet it was a problem with case. bash v6 and bash V6 are two different things. Capital V should fix the issue.
Save the txt file, it is the actual script that is being ran. Without it, nothing happens.

I used bash V6 (and tried bash v6 just to see if anything would happen) and I got the same message. I thought maybe I just didn't do it right first time around, so I went back in, checked the minfrees and entered option 15 and then 16 to reboot, but when it did, it booted to the stock Nook Color OS. I just shut down and turned it back on and it went into Cyanogenmod with no problem...but is that strange that it didn't boot into CM? And once I got into CM again, I checked the overclock settings and it was back down to 800 GHz (even though I set it on boot at 1200 GHz).

That's a partition, not a directory. Every partition has a separate root directory.
With emmc, it's simpler because there's only one partition on the sd card so there's only one root directory. You can copy it over using usb or a sd card reader and it'll end up in the same place.
If you are running off the uSD, transferring files via USB places them on the "SDcard" partition on the uSD. That way, CF3D can find the files.
**I have a ton of apps, which may be the cause of my app drawer stuttering on flick (where you try to swipe to the bottom of your app list in one flick).

Thanks for all the useful replies! I uninstalled Nook Color USB Mass Storage app, and it seems to be working fine!
I saw that there is a new build for [CM7.2-RC0] MiRaGe - KANG and was wondering if you guys could kind of walk me through doing my first update. I downloaded both of these files listed in his first post:
- ROM - 01132012 build: MD5sum: 41676325569e773340378ba886dd6bf6
- transparency theme with circular battery indicator for 01132012 build. MD5sum: 9fb6a03e91f01c162a2f8f37cfe8ac77 Flash this theme after booting once with the new ROM. Do not use this theme with earlier or later builds.​
For installation, it says "Just follow the official CM7.1 installation via recovery guide (stable or nightly). The removed components will be retained on your NC from the previous ROM if you do not uninstall those (Titanium recommended) or do a clean wipe."
I do have Titanium and I backed up using the "all user apps and system data" option. Is that adequate or is there a different option I should be using? Also, since he mentions that the removed components will be retained on the NC if you don't uninstall those...how do you know which ones and how do you go about uninstalling those? I never actually used the uNooter or ROM Manager...so I'm trying to figure out how to make it work with the method I used the first time around (VeryGreen's: http://forum.xda-developers.com/showthread.php?t=1000957) What I've done is just renamed "encore_CM72-MiRaGe-01132012" with "update-" in the beginning, put it on the boot partition, and rebooted into recovery.

wrong button click, LOL
Anyway, that should be it.

Yeah, my NC seems to be working fine after just renaming it to "update-" in the beginning of the files and booting it into recovery, but the transparent battery indicator theme didn't seem to do anything
Also, this is a random question, but do your NCs' volume rocker thing seem kind of loose? I was just wondering if that's normal because mine you can move left and right (you can kind of wiggle the button itself).

My volume button does that too.

Oh good, I was hoping it wasn't some sort of issue with the button being broken or something.
Also, I asked this earlier, but could someone explain to me what to do since after updating a new [CM7.2-RC0] MiRaGe - KANG build, he says "The removed components will be retained on your NC from the previous ROM if you do not uninstall those (Titanium recommended) or do a clean wipe. If you don't need a clean wipe, i.e. current ROM is CM7.1, instead of step 5 in the guide, do wipe dalvik-cache only."
Is that what I should be doing? How do I go about it using VeryGreen's method (without using ROM Manager or ClockworkMod Recovery?)
I'm sorry if I just sound like a complete noob, but I'm trying to learn!
