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?

Hey guys,
I have had some issues with my current ROM. I want to change the ROM. I am looking to switch to OMEGA.
How would I do this, I currently have AROMA rom. Should I do a factory reset the just reboot into recovery mode and install that way? Or will just installing the ROM from zip work? Or if I do a factory reset do I need to root it again with Odin, or will I not need to root it?
Also for wiping the phone should I wipe my SD card? Or no?
Thank you I searched and found half answers for most of this.
You have to format /system partition and /data partition in order to get a clean ROM, otherwise you may run into some unforeseeable problems.
Don't have to wipe sdcard
Most ROM except stock are pre-rooted.

Ok just to double check what your saying.
I should do a wipe using the built in android factory reset.
Then just install the ROM using the recovery boot.
I will not have to use ODIN or any other soft ware. Just factory reset and install rom.
AW: [Q] Switching ROM and wiping
I'd factory reset in recovery, wipe cache and dalvik, format system and then flash the new ROM from your external sdcard
Please report if that way worked for you
But be sure to backup your apps with titanium backup

6.Install zip from sd card , Choose zip from sd card , Choose rom and Click yes!

Nobody can tell you which rom is better .. All roms are amazing because of the work put into them try them out one by one.. you're not going to lose anything..
Ok cool. I installed OMEGA and I like that rom. I did a factory reset and wiped the Dalvik cache and cache. Will look around a bit more but so far so good....
however same issue with the phone. But now when the call ends it says process com.android.phone has stopped. Then i hit ok and phone is ok. It doesn't automatically restart then go really slow.
No idea about this, I searched however couldn't find a answer. Lots of phones and versions of android had this issue.
Any ideas would be great guys.

why not you backup your current rom first then try to flash a new rom without wipe data. if you not facing any issue on the new rom, then it's ok.
if you facing any issue, you must flash again the new rom with wipe all data. if you not happy with both, then you restore back what you are backup before.:fingers-crossed:

There is no white data. only buttons available are force stop and clear data. If I press clear data it says all data will be deleted permanently including all files, settings accounts, databases. I assumed the files were the actual app.
I went to settings. Applciation manager and chose Phone.
......hit clear data then, do that for phone and contacts storage, the data bases get rebuilt the only thing you will have to set up again is which contacts to display and any ringtone options etc you may have chosen

Can you nandroid backup in recovery? If so I would do that or titanium backup and copy the backup to PC then use the link below to get back to stock. Then you can update to 4.4.2 root with ioroot25 and use autorec to get custom recovery (twrp).

It's not exactly a clone of the whole phone. It's basically a clone of the currently installed ROM including data, settings, cache. To back up your apps and stuff use Titanium Backup or Copy. To backup music and video and photos, sync that to cloud storage or copy to your pc.

Oh ok my bad on that part then I was told it clones all your data rom and all. I did a backup and restore
and I had everything from before but I guess its because I didnt factory reset the phone.

Yeap, each phone will behave differently and for this specific G2, Factory Reset will wipe EVERYTHING.

So when people say to wipe everything like when installing a rom do they mean factory reset from the settings menu or from recovery?

Oh, no no, especially on this G2. Nope, don't do that.
"Wipe" when updating/installing new ROM is
+ wipe dalvik cache // a must regardless of dirty install or clean install
+ wipe data cache (?) // a must regardless of dirty install or clean install
+ wipe data // this will wipe data partition. Must be done when fresh installing new ROM (basically not an update)
+ wipe system // only need in some case, generally, you don't need to do this step
For this G2, if you Factory Reset, you will lose every personal stuff that on the phone, all end-user partition.

Oh ok because for the Mahdi 2.5 rom for G2's he says to wipe "EVERYTHING". So I'm guessing that would be a case
where you need to wipe system as well then? Thanks for the clarifications.
I've been playing around with 5 Android devices and so many custom ROMs. Some do require FULL wipe including format system, some others don't.
Just read the instruction of the ROMs' authors and you should be fine.

Uhmmmmm, nope, not truth.
None of your personal stuff will be backed-up.

A nandroid copies the phone set up as is at the time of the back up. Everything, settings, call history, text messages, contacts, app versions... Everything!

Always wipe system when going from rom to rom. The new rom will install new system stuff.. Never wipe "internal storage"!
Hi, I'm not exactly new to XDA, however my Note is my first real Android phone. My question is this: If I want to make a backup of the entire phone, so that I can install a new ROM, then restore the phone to exactly the way it was before I installed said ROM, what do I need to select to back up in TWRP? I'm wanting to play with the Lolipop build for i717. I already have a good EFS backup stored separately just in case, so I need to select System, Data, and Boot, and this will save the kernel and the ROM contents, correct? ...and when I restore this backup it will be just like I left it, right?
Also, what do I need to select to Wipe to perform a 'Full Wipe' as is recommended before install?
Thanks for your time.

Use gimmeitorilltell's version of twrp as some specifics have not made it to official version. I've had great results using 2.8.0.0 though I believe some newer versions are working now as well. I backup android secure as well. Not sure if this is necessary, it was the default setting. Wipe is generally accepted as factory reset usually followed by going to advanced wipe and checking cache, and dalvik cache and wiping these again. Then install your new rom zip, gapps zip if required, wipe cache and dalvik cache and reboot. First boot will take a long time. Possibly as long as 5 minutes or more. Once booted let rom settle for at least 10 minutes before adjusting any settings. Good luck.
Edit: Your backed up rom system will restore everything back to the way it was if you desire to go back (installed apps and settings as well).

Thanks @developweb, works perfectly. Also thanks to @gimmeitorilltell for his TWRP and Lollipop ROM.

Hi guys!
I've been fiddling around with different ROMs. With every new rom I install, I always wipe data/factory reset, wipe cache + Dalvik cache.
However, it seems there still are files lingering from earlier versions (eg. wallpaper settings).
Is it possible, and if so how, to do an ultimate reset, to make the phone as bare as possible before installing a new rom?
I've tried using CM recovery, TWRP, CWM, and others based on earlier mentioned recoveries. Right now I'm running the latest Candy 5 (infected) + CWM
It's not quick but if you encrypt before wiping it that is one way. I've always reccomended doing this when selling your device.

usually I do a full wipe with TWRP (go advanced wipe and check everything including internal sdcard), this will wipe everything you have on the phone like pics and other stuff, so make sure TO COPY THEM FIRST, the are not included in a nandroid backup, had to learn that the hard way
There's no better wipe then what you do (except formatting sd card).
I think the settings that stay between flashing are the one restored by your Google account.
Uncheck backup / restore from Google settings next time you install a rom and it should be all new !

I'm quite sure it's more than just the google back-up files lounging around, but I'll make sure to try and set it up as a new phone next time around. Thank you for your help

If you mean files that are on your sd (internal or external) they are not Google's backup but have no big effect on your settings (except for some apps). If you want to get rid of this, just format your sd.
Now if you mean some settings like the wallpapers, they are restored by Google automatically but the setting is stored on the data partition (which you wiped).
Do you have other examples of things that stay between wipes?

Nothing that comes to mind, only the reoccuring feeling of "Huh? That shouldn't be there anymore". However, I'm quite sure I solved it using PhilZ to advance wipe and wiped everything but the boot.
