Since the script installer built into the boot partition does not format anything before installing a new ROM, sometimes it is a good idea to clear things out first. Or maybe your installation is acting up and you want to start fresh without formatting the whole card and losing your media files. You could use the modified Alternate CWM for SD to do it, but not everyone has installed that on their SD. So those zips are just an alternate (and I think cleaner) way to wipe your SD partitions. They can be flashed with any recovery (on emmc or SD) since they are hard coded to format those partitions on SD that are named in the zip title. They have safety checks built in to make sure that you have your partitioned verygreen SD in the slot before they will attempt to format anything. If you are just installing a fresh nightly and you want to keep your data, just use the system wipe (but that means you need to re-install gapps too). If you are having operational problems and want to keep the same ROM, just wipe data. Or if you are putting on a completely different ROM, wipe both system and data.

Thank you for the additional information. I'll be checking out the edited OP for tip B1. I also wanted to say thanks for the Alternate CWM for SD since my Paranoid Android 2.55 of 19 November started Boot Looping today after I had put a lot of time into getting it set up with all my apps and I used the Alternate CWM for SD to wipe the cache and the Boot Looping quit immediately afterwards!
[Nook Color General] leapinlar:
You might also want to look at item B3 and the tip about adjusting your dalvik cache. Since the SD install and the emmc install share the same cache partition, it is easy for the dalvik cache for emmc and the SD to get tangled up and maybe corrupted.

Anyone have any tips for supercharger?

CM10 is just far too laggy. Especially because the fiancee's nook is still running 7.2 and it whoops its ass in performance.

Here's what I have done:

- Installed busybox (not sure what this does)

- Installed Script Manager

- Ran V6_SuperCharger_for_Android-update8.sh.txt as su

- Chose option 12 " OOM Group Fixes - Bulletproof launcher

Then I rebooted. Anything else I should try?
[Nook Color General] hwong96:
CM7.2 has the option to set max CPU over 1.3 GHz which cm10 is maxed at 1.1 GHz. I ran CM7.2 at 1.225 GHz and it was faster than CM10 at 1.1 GHz. We may be pushing the limit on this dated hardware.

Tip B3 Adjusting Dalvik Cache

Thanks again! I have created the local.prop file and put the recommended line in there. You were prophetic about the corrupted cache. I wasn't able to download/install apps on the Stock EMMC side. I was able to deregister but wasn't able to erase locally. I ended up doing the 8 reboots and reinstalling to factory (1.2) and upgrading back to 1.4.3. Unfortunately I had gotten frustrated with Paranoid Android because I was having to wipe cache every time or it would boot loop again. I hadn't read your reply yet and switched to the latest nightly of CM10. On the positive side, the CM10 is working well. The only exception being that the current Netflix didn't work, but I found a 1.8.1 APK that works fine. In the future, I might try Paranoid Android again now that I know what was probably causing its issues...

1.2GHz was stable on one of my tablets, where it rebooted often on another. I run 1.1 daily. I could never get it to run at 1.3Ghz without instant reboot/lock within the first few minutes.

Nook died and won't power up

Hi - Noob here. My daughter was using her rooted nook while slow charging from an airline usb power port. The nook died (screen went black) and I haven't been able to get it to turn on since. I have replaced the battery and used a new charger with no effect. Any suggestions would be appreciated. Near as I can remember I had an older CWM (3.0.2.8?) and Cyanogen Mod 7 running. I read your other posts but didn't see a fix for this. Hopefully this is the right forum. Thanks.
[Nook Color General] leapinlar:
It is probably because the boot partition got formatted or corrupted. The Nook will not power on unless there is a working boot partition or a bootable SD in the slot. Go to item A10 and make my bootable CWM. Try booting with that. If it boots, you can flash a new ROM. If the CWM boots but the new ROM does not boot on its own, go to my partition repair thread linked in my signature and flash the 145678 repair and format zips.

Still trying

Hi. Thanks for the quick reply. I made the A10 bootable CWM, but the nook will still not power on. Any other suggestions? Thanks.
[Nook Color General] leapinlar:
There are two possibilities. One, the battery is still not charged, which I doubt. And two, the card did not get burned properly. Try looking at my A9 and reburning a few times. Like I said it will show no life unless it can find something to boot to. Try plugging your Nook into your computer's USB port with the bootable card in the Nook. If it still will not get going, the Nook may be toast.

Sent from my Nook HD+ Running CM10 on SD
[Nook Color General] f16jack:
I tried the A9 reburns with no luck. I then held the Power and the Home buttons at the same time while connected to my laptop first with the nook cord and then with a regular USB cord. After about 15 seconds the computer sees the nook. I received a message on my laptop: "Installing device driver software" and the device was "OMAP3630". But after about 2 seconds the nook fell off and was no longer present. This is a repeatable process (about 2 seconds and then not present). The nook itself shows no life during this process.
[Nook Color General] leapinlar:
Ok that is good news. That means it is not toast. It is loading just enough to see there is nothing in the boot partition and turning off. You have to keep trying to make a bootable SD. Try a different PC. Different cards, different card reader. It is alive, just not well.

Oobe problem

07/28 - Added Skip Oobe (Out-of-Box Experience) for stock Nook Colors to section A

Hi! LeapinLar

I successfully did the procedure for Oboee and as a result I'm unable to listen to music or see video, though I hear a click when starting the tablet.

Whether it's for sound or images a download process starts but then the screen turns desperately black..

Was such an incident ever recorded?

Canceling Oboee wouldn't help as my old email account at Barnes and Noble was canceled and the new one is not recorded for the same serial, this is was I did Oboee)

Now I'm in the process of rooting on an SD card according to your instructions.

Would you have a tip to solve the problem?
[Nook Color General] leapinlar:
I don't know why you are having problems with music or video. Maybe it wants to verify your account.

But back to your account info and registering. If the original account was yours, you should be able to call B&N and get it deregistered so you can reregister.

Hi LapinLear

very nice dev ! no freeze or SOD on nightly build 20121210

even bluetooth is back :)

only one problem : Svox (v2.0.14) put a message 'TTS settings parameters' but impossible to fix .. no choice for Svox,

only offer pico or google voice

( on CM7, svox was ok, may be I have to reinstall CM10 by upgrading CM7 (?)

EDIT : upgrading CM7 by CM10 don't solve problem : TTS settings parameters still give only choice between Google or Pico voice, no Svox

many thanks for your working :)

cm-10 update

LeapinLar,

Firsts off Thank you very much for always being there and taking time to write such detailed instructions.

I have a question around the SD Card CM10 install.

CM10 w/h SD Card works awesome, now I am trying to update my cm10 to the latest nightly update, I looked at the B4 instructions, and I personally find putting the SD Card into the computer much easier, although the SDCard Partition is fat32 when i insert the sd into the computer windows asks me if I want to format the disk, when i click cancel I have no access to the SD Card.

How do I go about updating to the latest Nightly if I can't put the update-*.zip in the SD card partition?

I personally think I am missing a step here.

Regards
[Nook Color General] leapinlar:
When you say you insert the SD into the computer, you mean you physically remove the card and insert it into the card reader? It is sounding like you are plugging the cable into the PC by the symptoms. No one has ever said removing the sd is easier than using sdboot.

Obviously the PC read the card ok when you copied the first cm zip there. So it should do it now.

Sent from my Nook HD+ Running CM10 on SD
[Nook Color General] sjallipa:
I mean via a SD card Reader.

Yep it is true that I had no problem copying the cm zip file during the initial install.

I am looking for something obvious I might have missed.

So if the SD card reader doesn't read, what are my options?
[Nook Color General] leapinlar:
You have two options. First option is to install my sdboot script so that you can see the boot partition inside the nook. The second option is to install the NookColorUMS app found also in my tips thread (Section B). It allows you to mount the SD boot partition inside the nook so that when you plug in the USB cable to the PC it shows up as one of the removable drives in windows. You have to use my version modified for CM9 and activate USB Mass Storage in CM10. Go to settings, storage, menu, USB computer connection and check off Mass Storage.

First of all, thank you for this great thread and your service to the color nook community. I sure hope that you can help me.

My nc is stuck in a boot loop.When I turn on the device in the usual manner I get the "cyanogenmod" logo with the words "loading..." below. After a few seconds, it reboots and repeats. Forever.

I can load CWM 6.0.1.2 from sd card. I also can load CWM 3.2.0.1 from EMMC. I have tried to use CWM to restore stock recovery without success, stock ROM without success, etc. In fact, I have tried EVERYTHING suggested above, including partition repair, reformating /data and /system. I am still stuck in the bootloop. If this helps, from CWM I am unable to mount /data

My best guess, is that even thought CWM reports that flashing is successful, that nothing is actually being written to EMMC (or maybe only partially to EMMC because when I mount USB storage from CWM I can see the ColorNook with the following folders .adobe-digital-editions; .android_secure; .docThumbs; .kdebug; B&N Downloads; LOST.DIR; My Files). Even though I have attempted to flash stock recovery to EMMC several times, I am still running CWM 3.2.0.1 from EMMC.

Is there anything else that anyone can suggest? I have some experience with rooting and custom ROMS and have used adb, but do not consider myself an expert. I've been working on this for 3 days and can think of nothing else. I would be even willing to ship this to someone if they feel they can fix it for a modest fee. Otherwise, I'm going to have to throw in the towel and post it on ebay for parts.

THanks in advance for your help.
[Nook Color General] leapinlar:
You said you tried partition repair. You tried my repair 145678 zip? And CWM reports it installed successfully? And after booting that it still sticks at the cyanogenmod logo. It should have switched to the cyanoboot logo. You are right, it is sounding like emmc has somehow turned read only. I have never heard of that happening to emmc, but it has happened to my SD cards before. When it happened to my SD, it acted like it was writing to it, but nothing changed. If it has, then you will not be able to run anything on emmc.

You might be able to run on SD though. But maybe not. The SD install needs to use /cache (partition 7) and /ROM (partition 2) to run properly. It's worth a shot though. If you can boot to a ROM on SD, but it acts wonky, you can avoid using /cache by adding the dalvik.vm line to local.prop as suggested in my earlier posts. And it only uses /ROM to write flags and if the flags are set right, it does not need it anymore. Play store also uses /cache for temporary download space when installing an app so it might not work either.

If you can't get either emmc or SD to work, it may be eBay parts time.

leapinlar,

First of all, this thread has been a life saver, thanks so much for it.

I'm currently running CM 10 on emmc and CM 7.2 on SD and so I've been using tips B3 and B4, that is I am using a shared media partition and mounting the SD boot partition. So right now when I update a CM 10 nightly I have update-sdbootmount-rev2.zip (for B4) and a modified vold.fstab (for B3) on the boot partition. From CWM I install the CM 10 nightly, then update-sdbootmount. My problem is that when I boot up the first time I still have the boot partition mounted at /sdcard because I haven't copied vold.fstab over yet. That means I get some folder cruft, etc. in my boot partition and I have to copy over vold.fstab to /etc and reboot.

My question is, is there an easier way to do this? Could I perhaps combined update-sdbootmount-rev2.zip with modifying vold.fstab for tip B3? How would I go about that?
[Nook Color General] leapinlar:
Well, the way I do it is to reverse which system you have on emmc and SD. I have CM7 on emmc and CM10 on SD. That way I rarely flash emmc so vold.fstab rarely gets overwritten. Then I have CM10 on SD and because the SD /system never gets formatted during a new ROM install, the 19sdmount never gets overwritten either. And the sdboot mount works great for updating CM10 daily. But if you do this it means you must start fresh with a new burned SD image. CM10 needs to use the rev 5 of my SD image file.

But if you want to keep it the way it is and flash the sdboot zip every time to emmc, it is an easy fix too. Just open the sdboot zip with an archive program like WinRar and move to the etc folder in the zip. Add your modified vold.fstab file there. Back out of the zip and it will be saved. Then when you flash it, it puts the modified vold.fstab file on your new CM10 /system for you along with the sdboot file.

v6 SuperCharger

Leapinlar,

Have you tried the V6 SuperCharger yet, what is your opinion in using the script in CM10, I looked through your index and didn't find any reference to it, so just got curious, I have been following your instructions so making sure you recommend it.

The only reason being my browser (any browser, default, opera, firefox, opera, dolphin) all have been pathetically slow, at this point in time just click on URL bar or for key pad to popup alone makes it dysfunctional, we are talking terms for several minutes.

Keep up the good work.

Leapinlar,

Thanks for all your work in putting together this and the other threads. They're great.

After successfully rooting my own NC (to Jelly Bean) and my wife's NC (to Gingerbread), both our sons wanted in. Rather than buy them new NCs, I thought to try eBay, so I purchased two NCs that were stuck in bootloops. I've encountered trouble with both of them.

The NC I'm currently working on boots up to the "Touch the Future of Reading" screen, but freezes. It doesn't seem to respond to any of my efforts. I burned a CWM 5.5.0.4 sd card as per your instructions, and loaded it with the emmc recovery zip and CM7.2 and gapps zip files to root it. When I put it into the NC and try to boot up, it goes to the CM bootloader screen, and then to the initial CWM menu screen with "reboot system now, install zip from sdcard," etc. However, I immediate get the following error message at the bottom of that screen:

CWM-based Recovery v.5.5.0.4

E:Can't mount /cache/recovery/command

E:Can't mount /cache/recovery/log

E:Can't open /cache/recovery/log

E:Can't mount /cache/recovery/last_log

E:Can't open /cache/recovery/last_log

Then, when I try to navigate through the menu and attempt a procedure I get some form of the preceeding error, e.g., when trying to install zip from sdcard I get "E:Can't mount /sdcard/."

with some attempted functions, additional errors show up

W:failed to mount /dev/block/mmcblk0p7 (No such file or directory)

W:Can't unlink /cache/recovery/command

When I try to reboot system now or reboot recovery, the machine just shuts off .

Also, when I try to run the machine off an sdcard with gingerbread (which works on my other machines), the NC boots up the initial dual boot menu, but freezes when attempting to access the sdcard operating system.

Any clue what's wrong with this machine and what I can do to get it up and running? Thanks in advance.

Your cache partition is borked. Go to my partition repair thread and run the partition repair zips.
[Nook Color General] judgerey:
Tried that. Loaded the partition repair zips onto the sd card. Booted into CWM, tried to "install zip from sd card", and got

"E:Can't mount /sdcard/"

Talk about being Borked. I think I'm beyond that. :eek:
[Nook Color General] leapinlar:
The cache errors can be explained by the internal partitions being messed up. But I don't understand the not mounting sdcard. Could be a bad SD. But that does not explain why the other card did not boot to completion. Maybe a dirty slot? You also might try my other version of the CWM card.

One of the things you can try to see if the internal partitions are messed up is to try to mount each one with CWM in mounts and storage. We know you cannot mount cache. Try the others. If you can get them to mount, then you can use ADB to look at them.

<Materod>'s method on applying the V6 supercharger scripts a good method also. The forums down in cyanogenmod are more for novice users and younger users like myself. I have put together a guide down in cyanogemond on applying the V6 supercharger script along with a modified services.jar. I will give the link for that.

Whether changing the OOM memory settings actually works in improving performance is a heated debate between the experienced developers that < leapinlar> probably wants to stay out of. Some of the most experienced developers think it does actually nothing and is more of a placebo effect. I feel it works and applying that script and mods gives me a chance to learn more on how android works. Last year there were heated discussions about that script for the 7.0.1 and the 7.2 nightlies and stable builds.

Here is the link for that guide I have on the V6 supercharger in cyanogenmod. Keep in mind about the app <materod> is working on called "botbrew" on the playstore. It has *nix tools for development on the go for your nook color.
