I DID some cache wipe and dalvik cache wipe and accidentaly included data wipe too..the phone rebooted and ask for goole etc etc to be filled up but then the phone died and when i tried to reboot it. I get stuck at CM7 boot screen. I tried recovery pressing power-volume down-menu all at onece and when i try to restore back up it says E: Couldn't open directory/sdcard/nandroid/ please help me please i dont know what to do
Did you move the nand backup elsewhere on your card or to your computer? Toggle USB storage and copy the nand backup back to the sdcard (and to the same folder).
no.backup was not moved ever since i created it using nand backup.and upon checking..it is still there
my guess is that the rom has become corrupt (somehow), so this is what i would do:
1. wipe everything again (as if you were going to do a fresh install of new rom)
2. flash cm7
3. once everything has booted properly, reboot into recovery and try to restore the backup
Im gonna try that one out sweet...anymore suggestions or solutions or is there anyone out there who knows exactly what to do?
Hoping your suggestion would solve this problem...Rebooting now after re-installing cm7......
Re-installed CM7 and phone went On..Tried to restore backup but to no avail....anyone who can suggest what to do?
did you rename the folder of your backup? i know that the name cannot have "invalid" characters, such as asterisks and spaces.
also try reflashing your recovery and try again.
I think I know what went wrong. Yesterday I used Amon Ra to wipe cache and dalvik cache and battery stats coz I've seen somewehere here in this forum that CWM recovery doest completely wipes caches so I used it but I forgot to return to CWM. I think that causes the problem "couldnt open file directory". Upon reinstalling CM7 rom, I flashed CWM and tried to restore backup and it did.
Nope..I never did anything with the backup...reflashing recovery solves the problem
so everything is now up and running? glad to hear that
yeah..up and running thanks
hi,
this ROM works very nice for me, thanks all the deveopers!
i have few questions:
(1) since this ROM has OTA updater (it seems, from the changelog), next time when the new version is realeased, can i just update the ROM via OTA updater?
(2) i dont really understand what “Wipe cache/dalvik” and “Wipe data / factory reset” really do. my guess is that “Wipe data / factory reset” repartitions the internal flash memory of the original memory, so we can use all the memory for our purpose. (not like original Nook Tablet, in which they dedicate only 1GB for personal usage)
if i understand all these correctly, this means next time if i flash the new ROM and want to keep the old data, i should not do "Wipe data / factory reset", but only need to do "Wipe cache/dalvik"? is this correct?
thanks so much,
Jun

Wipe data/factory reset is an option in CWM Recovery. Really all it does (from the screen messages) is format both /data and /cache.
Assuming you have CWM Recovery (though I imagine that there are similar entries in TWRP, I've just never used it), to wipe both of the caches you will first need to go to the entry "Wipe Cache Partition", which I believe is directly below Wipe Data/Factory Reset. Do that 3x (that's always been the recommendation, anyway) then go to Advanced and click on Wipe Dalvik Cache (again, 3x).
Again, assuming CWM Recovery, when you're in the recovery Vol Up/Down goes up and down in the list, the 'n' key is for Enter, and the Pwr button goes back.
I don't know about the OTA Updater. I always download and install ROMs (on both my phone and my NT) via Recovery.
Since this is a CM10 based rom you probably don't want to do the ota updater since that is a Cyanogenmod feature. This rom is optimized for the Nook from the CM10 Source I would presume. I personally tried the ota uldater since i get the notifications all the time but i get an error message something like "can't verify the source with a string of numbers". Stick to the recovery based flash installation.

I agree with liquidzoo that you should probably do the wipe cache, wipe dalvik cache and factory reset 3times seems like overkill but you can never be too safe. Also i use twrp recovery and click the system button and wipe system a few times as well.

I wipe /system 3x as well (under Mounts in CWM Recovery) when I'm installing a new ROM.

I'm not picking on you personally, but deleting and/or wiping partitions (in the case of /system) or directories (dalvik-cache) three times as opposed to once is completely unnecessary. You'll gain nothing by running the command three times over running it once, assuming you received no errors the first time.
When wiping the dalvik cache, both CM recovery and TWRP perform an "rm -rf /data/dalvik-cache" command using the shell. It's not Windows, and is unlikely to fail when passed the "-f (force)" option along with the "-r (recursive)" option.
In the case of wiping the /system partition, again both CM and TWRP write out zeros to clear the data on the partition. I would be suprised if CWM acted differently from CM and TWRP when wiping dalvik-cache and /system.
The only reason I bothered to look into what these commands actually do is to prevent a user from thinking there's a corellation between a failure to wipe 3x versus a problem they're having. If a 3x wipe "fixes" something for you, whatever the problem was, it's very unlikely that the second or third wipe was what fixed it but instead it was more likely a result of a clean install of the ROM.

Have fun modding!
No worries, it's just something I've always done as it's been recommended to me in the past (there are some ROM developers that recommend 5x, actually). I'm not saying that 3x over 1x is any better, but I've never had issues. YMMV, but it doesn't take much more time and I like being thorough.

sorry, but can you confirm that when i upgrade to the new ROM (from the same author), it is really necessary to Wipe cache &Dalvik cache?
i am confused because somebody told me that i can just flash the ROM by installing the ZIP file (containing the ROM), and reboot the Nook without having to wipe or clean anything.

I don't know if I am doing it right or wrong but I have flashed numerous ROMs and lately have flashed every version of SGT7+CM10+Cherry Picks,By meghd00t. from 24/09 thru my current installation of 08/10 with only one glitch and that was when I flashed enhancements v2 on top of v1.
I have never had any other issues with the above mentioned ROMs except when I flashed 04/10 with enhancement v2. I didn't have the tablet option.
The way I do it is as follows:
1. format /system
2. format /data
3. Flash ROM
4. Flash CWM emmc
5. Flash GAPPs
6. Reset Factory/format data
7. Remove CWM SD card put in data SD Card with Flash Player (no longer avail on Google Play)
8. Boot from CWM menu
Takes awhile to boot this first time. When booted up I bypass the setup screens.
9. Manually set up wireless (need to access auth web site at work and need wireless to be working to accomplish that)
10. Browse to a web site and get redirected to auth page.
11. Auth
12. Set up Google account and other settings, especially under Security <Install from other locations>
13. Download apps I want from Google.
At this first boot SD card is not mounted.
14. Shut down and do a cold boot.
Now I can see SD Card.
15. Install Flash Player from External SD Card.
16. Install Crackle from Play Store.
Now I check Pandora for Audio, Crackle for Video, other apps I use, utilities, keyboards, launchers, games, etc.
So far since Version 24/09 everything has worked for me with the two exceptions above, tablet mode with 04/10 with enhancement v2 and when I flashed enhancement v2 over enhancement v1.
I am now running 08/10 and am very happy with the performance, battery drain is more than CM7 but that is to be expected from a fairly new ROM but not so bad that it is unacceptable, to me at least.
I have never had a black screen or arbitrary reboot (knock on wood). However I do turn my tablet off when I am finished using it, so don't know about deep sleep. I'm using OnDemand, and three launchers without one being the default....Apex, Nova and Trebucket.
All I can say is these developers really ROCK, way to go guys!

You don't need to re-flash CWM every time you flash a ROM. Also, it doesn't make sense to me why you would do a factory reset/format after flashing the new ROM, I would think it would be done prior to flashing the ROM but maybe it doesn't make a difference, I don't know.
I've got TWRP installed to the emmc so I just download the new ROM to the SD with GooManager, reboot into recovery, do a backup, factory reset, flash new ROM & GApps and reboot. Only takes a few minutes.

Tried it as you mentioned, doing a factory reset before flashing the ROM and got a black screen and wouldn't boot. May have been a fluke but the way I mentioned above gives me a good image and alway boots. Don't know why, but if it works for me, I will continue to do it this way as long as it works for me. I have flashed numerous other ROMs the same way with good results each time.

For an update, yes it is recommended to clear both caches. To be clear, this is only for an update. If it is a new ROM, or if the author recommends it, you should also wipe /data and /system first.
You can just flash without clearing them, but you might run into unexpected issues, so it's not recommended.

I get a black screen for a while on first boot too, but it only last a couple minutes at the most and if you shine a bright light at the screen you can see the CM logo spinning. Are you sure it was hung?

When you clear the Dalvik cache, it clears out data stored in your applications. When you turn on your Nook after clearing the Dalvik, the first thing it does is it rebuilds the Dalvik cache, that's why it seemed like it hung on startup. I believe the long black screen in the beginning is when it rebuilds Dalvik for core Android apps and then when it says "Optimizing Apps", that's for the rest of your applications. The more apps you have, the longer it will take to build the Dalvik. No need to freak out, just a little patience is all you need. Correct me if I'm wrong, however, as I'm still pretty much a noob at this... :laugh:

Well fhe screen was black, no light at all and I waited for over five minutes for the Flash Screen to come up and it never did. Yes I know when you are waiting time drags. But due to the ROMS always taking awhile to boot up the first time I actually pay attention to how long it takes. No more then 2 minutes in my experience. I had to hold the power button in for a long time until it finally booted in B&N Recovery. Used my sequence mentioned in earlier post to flash the ROM again and everything worked as it should, GREAT. The number of APPs shouldn't be an issue as these ROMS only have the very basic apps.
I have read this forum and see the various and asundry errors some are getting, so far I have never gotten a major error, except for when I forgot to do the Wipe Data/Factory Reset after flashing.
I also got the "No Tablet Mode Option" with 04/10 with enhancement v2.
But I consider these minor issues and currently am running 08/10 with no issues, works smoother then any version of Microsoft Windows I have dealt with.
These developers are exceptional.

oh, so you always reset factory every time you upgrade the ROM? that way will delete all the old data/apps you installed, so you need to install all the apps again?
this is my concern, because i dont want to reinstall apps, or lose my data. so i think i just need flash the new ROM, then Wipe cache/Dalvik cache, and hopefully all the old apps and data are still intact.
thanks.

i have some questions on the "Enhancements":
(1) the correct way to install them is to flash version 1 first, then immediately flash version 2 right after version 1 (without having to reboot first)?
(2) i am not sure what i will get with this "enhancements". they will make video/audio playing more smoothly? is the quality improvement really noticable? anything else, like they make the battery last longer, for example?
thanks,
Jun
If you're running 08/10, the enhancements are not needed. That's my understanding at least. I had problems with V2 so I decided to not install them while on 04/10.

If you flash enhancement v2 on top of version 1 you will have problems, UI will stop. If you only flash v2 you will not have the Tablet Mode Option. So my understanding is that you can use either v1 or v2 but not both.
ROM 08/10 does not need either enhancement as indicated by the developer. ROM 08/10 works great by itself is my experience.
If I'm installing a ROM, backup the existing ROM and wipe everything.
If I'm installing a .zip package like GApps or an enhancement, backup the existing ROM, wipe Data/Dalvik.
Folks, these are development ROMS. Thar be bugs in thet thar code. It's going to take you longer than the time you think you're going to save by doing a dirty flash, and then having to restore the thing to stock (worse case) only to start all over.
Don't ask how I know.

so it is possible to back up the existing data/apps, then restore them back after the new ROM is flashed? could you please confirm this?

Fellow Users,
I wiped:
- Factory/Wipe data
- Dalvik
- Cache
- Every storage
did a fixed permission
- Switched different roms Stock and Custom
- Switched different kernels stock and custom
- Flashed with Odin and with CWM Recovery.
How can i get rid of the nasty scripts or mods that are stuck ??
Is there a way to clean everything harder and deeper than what i did ?
How about init file or something?? i dont have ADB
I think this is how. follow these.
1. Factory reset / Wipe data
2. Wipe Cache partition
3. Wipe Dalvik
4. Go to mount & storage
5. Fix Permissions
6. format /cache
7. format /system
8. format /data
9. format /preload
10. format /sdcard
Try these. But make sure you have a rom to flash on external sdcard. because formatting these will remove system and you will not start phone without flashing a rom.

To fully format the phone you could also use megawipe. It is a flashable zip for cwm which will remove anything, also your sd card. Hence better have a flashable rom on your external sd. You can find it in the dev section or search for mega wipe.

Maybe it is hardware related? is there a way to test this?

Maybe let us now what you want to delete exactly.
Usually the mega wipe well erase any file and leave a blank slate.

Yes I was under the impression that you could just use Mobile Odin to flash your ROM's..
Do you also need to have CWM recovery?
BTW, I'm flashing stock firmware now..
Problem fixed. just had to choose 'Full Wipe' in the installation process of Omega..
I am getting a fc in setup wizard after installing the Infamous ROM 4.3 "pac_p4_4.3-Infamous_20131017.zip".
Followed below steps:
1. using CWM 6.0.2.7, wipe data/factory reset
2. wipe cache partition
3. wipe delvik cache
4. Flashed Infamous ROM
5. Flashed gaps "gapps-jb-20130813-signed"
6. Reboot
after getting the fc on setup wizard i tried, 1) wiping cache and rebooting 2) reflashing the infamous rom on top again.
both solutions did not work.
I am coming from Ganbarou 4.3 ROM and before that i had Toldo's v8 ICS rom. Ganbarou ROM was working well.
Just wanted to test different JB 4.3 roms.
can someone help me out?
thanks.

First you need to update your recovery to 6.0.3.6. You can get it from Droidbasement.
Secondly, before flashing you need to format system under Mounts and Storages in addition to the wipes you mentioned above.
After installation wipe cache and dalvik cache again and then reboot.
The gapps is okay as it is same as mine, and I never had any issues.
Cheers.

Great advice...
I also always suggest a system format...
I just wanted to add that with the older recovery...it doesn't like 4.3 gapps. You can boot after ROM flash. Then go back to recovery and flash gapps...wipe cache and dalvik before. And that will work also and I've seen gapps cause some weird issues with this device as well as my e4gt..
Or just use twrp...I've had zero issues with flashing anything since switching...
Thanks for the advice. (John and Gil81)
I followed the steps as advised i.e.
1. under Mount and Storage, format system
2. format cache
3. format data
4. flash rom, this time i flashed CM10.2/SGT7 rom.
5. reboot
everything was working smooth, so moved on to
6. flashing gaps
7. reboot and now
8. Enjoying. (restoring apps)
great work from all the developers of 4.3 roms for our device.
have not upgraded the CWM recovery yet, but please advise if it is absolutely necessary to do that. May be i would do it with any future upgrades.
also to get better understanding of the recovery, what is the difference between format data and format sdcard option?
thanks.

Formatting sdcard will wipe everything in your device including the media partition where your user generated data like pictures, videos, downloads etc and also all the files copied to the device from PC. So be careful NOT to format the sdcard.
Formatting data, on the other hand will remove your installed gapps and the associated data. This is necessary when migrating from an older ROM to a newer one that will need you to install different version of gapps that is suitable for the newer ROM. Even when crossing from one ROM to another based on the same version of android, it becomes necessary to format data to get a clean install so the data from the different ROMs do not conflict.
The recovery version, as I understand it, is necessary for the changes to the filing system of 4.3 which is different from 4.2.2. In addition it is also designed to support the multiuser feature of 4.3. I am a single user so I can't attest to how it helps there.
Cheers.
