Yeah, I just flashed from EB01 SC 292 to ED01 MIUIWiz after full Data, Cache, Dalvik, and voltage double wipes, and restored all my old EB01 user Data and apps over MIUIWiz, all in under 17 minutes.
Edit: adding navenedrob's utility method has cut this down to under 10 minutes, plus navigation and reboot time. See post #5
How? Just followed what the Devs have taught us, plus Nandroid Advanced Restore in CWM.
I have been doing this for every ROM I have flashed since I discovered what a Nandroid backup was.
But this is not just a Nandroid Backup. This is a partial restoration called “Restore data” under “Advanced Restore.” All in CWM recovery.
Here is the method I use:
Charge to 100% (At this point, I started the timer)
Boot to Recovery
Wipe Cache and Dalvik (and Voltage for MIUIWiz) x2
Make a Nandroid backup
Wipe Data x2
Flash the new ROM (of your choice) in CWM
Let it boot
Boot to Recovery
Select “backup and restore”
Select “Advanced Restore”
Select the Nandroid Backup file you wish to restore from (probably your latest one)
Here is where it gets cool, and less scary…
There is yet another page, with options:
Restore boot
Restore system
Restore data
Restore cache
Restore sd-ext
+++++Go Back+++++
So no sweat yet
Select “Restore Data”
Reboot completely
Turn off phone (here is where I stopped the timer at 16.5 minutes)
Charge to 100%
Boot and enjoy.
BAM! All the old data is back. On top of the new ROM. Except for stuff that no longer applies, like maybe in-ROM launchers that no longer exist.
My ROM flashing evolution path has been:
Stock
Odin DXC DB/DO tar
EC01 DB/D0 (zip i think, can't remember)
Full ED01 (Adrynalyne method, not OTA)
ComROM 1.0 zip
Evil Fascination, all variants in sequence. Zip
EB01 SC 2.9.2 zip (Why? To see if it would work. Because it means restoring ED01 Nandroid data over an EB01 ROM. Without compromising the ROM. (Thanks for the assistance with this, Lttlwing16.)
ED01 MIUIWiz
Seems to work flawlessly so far. No forced closes, no hiccups, just sweet functionality. Every time so far. And so quick, I sometimes actually have time to use my phone between flashes.
As I said, I have been doing this for just about as long as I have been flashing through CWM. Your backup may overwrite some ROM theme elements, so that is something to think about.
Any other drawbacks? Not that I have found, but…Not completely sure yet, So… You know the drill…
DO NOT TRY THIS UNLESS YOU ACCEPT FULL RESPONSIBILITY AND ARE PREPARED TO DEAL WITH THE CONSEQUENCES!! YOU MAY LOSE DATA OR FUNCTIONALITY!! YOU MAY EVEN MANAGE TO BRICK THIS THING!
But you just made a complete clean-wiped Nandroid Backup, right? So you can always restore the whole thing. Or worst case, do the Odin recovery method. (or even worse case, Heimdall).
I suspect that there is some reason that this method has not been widely promoted already. It seems unlikely that it has not been experimented with, so maybe someone can help show a newbie the error of his ways. Or we may need someone with a thorough knowledge of Fascinate ROMs to add some warnings, caveats, or guidance around potential problems, etc. But it does seem to work just fine for me, and all of the ROMs I have worked with seem smooth and stable. All my apps always work, and update properly. Unless I get stupid and screw something up.
It does seem that Android should be able to pull this off if sufficient attention is given to file structure and dependencies, and if everything data can be kept where a data only restore would look for files. I suspect that I have been having success because of the good work of all the great ROM builders and developers working to fix the Fascinate, and make our experience all that it is. So if this works for you, they are the ones that really deserve the credit and the thanks. They made it work. I just followed instructions, got curious about Nandroid Advanced Restore, and pushed the right buttons. Oh, and wrote it all down.
Wiping data and dalvik cache is kinda pointless because it gets overwritten and replaced by the restore anyway. Dalvik cache is located in the data partition, not the cache partition, ironically.

Well, I am expecting to learn something from posting this. So thanks. However, it raises more questions for me.
Does it mean that I never have actually needed to wipe data? I could have flashed all those ROMs without wiping data and without issues?
My understanding was that at least the cache would be re-written as needed by the new ROM, rather than trying to work with data created by the old one.
It sounds like it means that if bringing back the old data works, keeping the old data would have worked, too. So even Dalvik could have been left every time?
My thinking was that cleaning the cache and Dalvik before making the backup would mean that when restoring, they would come back blank, and not confuse the new ROM. I was under the impression that something was more likely to go wrong if all that stuff was left in there, and it was safer to bring it in later, after the ROM boots up, and give the new ROM a chance to properly recognize and deal with it.
Is there any logic in that logic? Just asking, because I really don't know. It sounds good.
If not, this thread is for educational purposes only.
But dang, either the Devs are even more awesome than we thought, or I must get lucky a lot. Because I have flashed quite a few ROMs without issues, force closes, etc.
Interested in more feedback on this process.
OK, I did have a couple of FCs of Gmail this last time flashing MIUIWiz, going from EB01 to ED01. It seemed to fix itself after I closed it twice, but I updated Gmail anyway. No repeats.
I have a new preferred method of backing up, cleaning the files, flashing new ROMs and restoring my data. Flashed MIUIWiz 111 over EF 360, the whole process taking about 10 minutes altogether plus navigation and boot time.
(Always create a clean Nandroid Backup (with wiped cache and Dalvik, possibly voltage) 4-5 minute process, not included. This should ensure that the new ROM will create its own compatible cache data after the restore.)
1. Run navenedrob's reformat utility [UTILITY]EXT4/RFS Formatter (CWM3 recovery packages) - xda-developers as a CWM zip from sd card <1 minute process.
2. Flash the new ROM in CWM <1 minute process.
3. Flash new Kernel if needed (before allowing ROM to boot) in CWM <0.5 minute process
4. Allow ROM to boot (3-4 minute process)
5. Nandroid Advanced Restore in CWM (Data only) (3 minute process)(Restores all User Data and apps)
From navenedrob: “Understand that this [format utility] will completely wipe your system, data, datadata (dbdata), and cache. This is a "full" wipe of the device.” But it also puts things back in order if they have gotten screwed up. This could be the solution to issues you are having. Thanks, navenedrob! Very cool.
If there are particularly desirable user setups in the flashed ROM, be advised they may get lost in the restore.
The only issue I seem to have is the need to update/install Gmail. Then all is smooth.
Works for me, but you may totally bork yours. You are responsible for what you decide to do.

I think that means wiping data also wipes Dalvik. So Dalvik wipe is redundant when wiping data. Good to know about the partition info. Seems to support the idea that wiping Dalvik before making the backup would ensure that when the restored data is brought back, it brings no Dalvik data with it, avoiding potential issues with the new ROM.

How much wiping do you need to do when you are upgrading to a new ROM release? I don't really want to have to go through all of the setup every time a ROM is updated. What does every generally do?
I'm running the G-Harmony ROM.
Use Titanium backup or the like to take a backup of everything if you are upgrading from one version of the rom to a new version. At first I wasn't backing up and spent hours getting everything back to the way it was. Now, in a matter of minutes I'm back running the same way I was before, but on a newer ROM.
Take the backup -> copy the backup folder to your micro sd card or computer -> follow the steps to install the ROM (do what is recommended such as the user data, dalvik, cache) -> once the rom is up and running, copy the backup folder back to your tablet -> download titanium backup, it will see the folder you copied over containing your backup-> restore data, apps, user settings from titanium backup.
I'm not sure how it works if going from ROM to ROM, probably want to search on it.
Cool, that's pretty much what I did. Unfortunately, I hadn't copied off the TitaniumBackup folder, and the new ROM version switched the emmc and SDCard mount locations, so I had to switch them back to be able to get at my backups. I didn't have an external micro SDCard reader with me, so I couldn't easily copy the folder from the internal card to the external. Ah, well. Going through the Titanium restores right now. I really should buy this software to prevent having to approve every restore
chadness,
One of the main things I try to help people here with is boot loops and I spend a
lot of time trying to figure out the cause so we can prevent it.
IT IS MY OPINION that one of the things causing the boot loops and making
people have to re-flash and re-partition -- is the stuff leftover in flash after
flash playing with their tablets.
I'm not sure the Android file system is all that good. I don't believe in tablet formats
because it doesn't work like a hard disk. You can delete a file and go back later and
the file is still there. You can nvflash the tablet and stuff is still let there.
When stuff gets left over it can conflict with the new stuff and BAM -- boot loops.
All of this is to say -- I SAY before every ROM burn you should nvflash to a solid
version -- bekit 1105 (2538) or 3588 -- the repartition to 2048 and 0, Fix Permissions,
Wipe Dalvik Cache, Wipe Cache and Wipe/Reset Factory Data.
I can't prove it yet -- but I bet if people would do that most of the boot loops would stop -- and probably some of the other little stuff too.
This is just my opinion -- but then I have only nvflashed either of my G-Tablets one time in five months now (involuntarily -- because of problems.)
Think about it.
Rev
Interesting! I've been flashing different ROMs this week and haven't run in to any problems as long as I've formatted system and data.

Rev, what is your opinion about using 'Calkukin's_Format_All.zip & wiping Dalvik Cache' vs all the above steps ?
Hello, I always find the people on this corner of xda very helpful. As usual, I think I know what I'm doing, but I'd like to check that I am proceeding in the right direction.
I've been using Mik's Cyanogen ROMs on my Optimus One. That's going well. But I need to SIM unlock my phone and I need to go back to a stock ROM to input the codes (please let me know if this is incorrect).
Before installing Mik's ROM, I performed a Nand backup. I have boot, cache, data, recovery and system img files. I think I can flash these through recovery and I should be back to stock.
Do I lose my apps and settings by doing this? Do I need to clear any caches?
What about returning to Cyanogen after I unlock my phone... Do I have to root my phone again or will I still be able to flash using recovery?
Using Clockwork, I just backed up my current ROM. I assume I will be able to restore from this later.
Is there anything else I should be aware of?
Thanks for answering my questions / clearing up my confusion.

to revert back to stock, you must wipe data/factory reset, cache, and dalvik cache. you will lose your settings. as for your apps, you can back them up with titanium backup and restore them after you have restored your backup.
What about returning to Cyanogen after I unlock my phone... Do I have to root my phone again or will I still be able to flash using recovery?
when you restore your backup of the stock rom, you will still have root. i dont think unlocking your phone will cause you to lose root. your root access and custom recovery will still be intact
Using Clockwork, I just backed up my current ROM. I assume I will be able to restore from this later.
yes this is true
Is there anything else I should be aware of?
just to be on the safe side, please list the steps you are going to follow
Thanks for answering my questions / clearing up my confusion.
Thanks for the quick answer...
I on my sd card, I have a /clockwork directory with two subdirs. One is my original backup that I made before first installing Cyanogen. The other is the one I just made. Both contain boot, cache, data, recovery and system img files. The difference is that with my new backup the image files have an extra yaffs2 suffix: cache.img (stock) but cache.yaffs2.img (Cyanogen). Any problem here?
1. boot into recovery
2. restore stock from my sdcard using nandroid and wipe caches as you indicated
3. reboot, enter unlock code
4. reboot into recovery
5. restore current ROM from my sdcard using nandroid and again wipe the same caches
6. reinstall / restore apps (I'm not using Titanium, instead I backed up the list of installed apps)
Will I need to find and reinstall the GoogleApps (Market, etc) or will they come with the backup of my current ROM?
Pretty simple really. This make sense?

there might be a problem. what clockworkmod version did you use to make the backup of the stock rom? if i remember correctly, using cwm 3.x.x.x backs up a certain way (and also does not have the yaffs2 suffix) and using cwm 5.x.x.x backs up a different way (with the yaffs2 suffix) so backups may not be "inter"compatible (more info on that here). however, you can just flash back cwm 3.x.x.x right now (you can do it using rom manager), restore your stock rom backup, do the following steps, flash back cwm 5.x.x.x, then restore your backup
1. boot into recovery
2. restore stock from my sdcard using nandroid and wipe caches as you indicated (i recommend wipe first then restore)
3. reboot, enter unlock code
4. reboot into recovery

6. reinstall / restore apps (I'm not using Titanium, instead I backed up the list of installed apps)

i think you will have to flash gapps again

I followed your instructions (I downgraded Clockwork before starting) and the 10-20% chance of you being wrong came true... but in a good way
Restoring from the backup brings everything back: apps, settings, contacts, SMSs etc. So it was actually even easier than you suggested since I didn't have to use my backups at all.
Thanks again for the tips!

Yes... when I was back in stock I could access the unlock menu by entering 2945*#500# on my keypad. The SIM unlock code that I have worked fine. I haven't actually tested with another SIM card but the phone claimed to have been unlocked, so I should be good to go.
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'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.

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.
thanks,

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?
Sent from my Barnes & Noble Nook Tablet using xda premium
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:

When you clear the Dalvik cache, it cleares 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.

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

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,

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?
if so, how & what is the right steps to do the backup? can we still use CWM, or use ROM Manager, or other tools?
thanks
So, after much research and trepidation, I flashed my first ROM to my i717 last week. Then I decided I didn't like that ROM and flashed another an hour later. So far it's been stable and speedy. I'm very happy. Thanks to XDA-Developers, Google, the Internet, and everyone who made this possible.
So, now, here's my simplified guide to doing what I did. This should NOT be taken as gospel. Please read as much as you can first. But, in an effort to give back, I thought a simple, step by step guide (or, more like links to the guides I found helpful) would be useful to someone. Are we sitting comfortably? Then let us begin.
1. Go here - http://rootgalaxynote.com/galaxy-no...y-note-sgh-i717-icsgingerbreadeasiest-method/ - and root your phone. It will also install ClockworkMod Recovery. Both of these need to be done before you can flash a new ROM.
NOTE: I hear that TWRP is the preferred recovery app. I've tried it and it's very nice. It just so happens that I had ClockworkMod installed when I actually decided to flash a ROM. But use whatever you like.
2. Go to the Play Store and buy Titanium Backup Pro. Well, actually, download the free version then buy the Pro key. There are other backup methods, but I like this one.
3. Backup EVERYTHING. You might never restore a particular app, but best to have it and not need it than need it and not have it. I like to use the Google Drive option in Titanium to push by backup off my phone. But you can just hook it up to your PC and copy the backup folder from your SD card to your PC. This is just in case something REALLY bad happens. Best to have an off-phone backup.
4. Find a nice ROM to settle down with. I'm using Revolt (http://forum.xda-developers.com/showthread.php?t=2288566&highlight=revolt) but do your research and find one you like. If you decide to go with something built off Android 4.2 or 4.3 then you'll lose the Samsung Touchwiz stuff (fancy SPen features, etc.), but to me that wasn't as big a deal as I though.
NOTE: Make sure you know if the ROM need an additional Google Apps package. Sometimes they're listed with the ROM, sometimes not. Read and make sure or you could lose a lot of phone features or it may not even boot. Again, READING IS YOUR FRIEND.
5. Save the ROM (and GApps file if needed) to your phone's SD card (internal or external doesn't matter)
6. Boot into recovery (Hold Vol UP+Vol DOWN then press PWR and hold all 3 until you feel a vibration, then let go of PWR). When ClockworkMod (Or TWRP) comes up, RUN A BACKUP!
7. Read 6. Make sure you actually do it. I'll know.
8. Once you're sure you have your Titanium and ClockworkMod backups, follow the instructions for installing the ROM. Usually this involves (from ClockworkMod or TWRP):
a. Factory Reset
b. Wipe Cache (this is usually a part of Factory Reset, but doesn't hurt to do again)
c. Wipe Dalvik Cache (see cyanogen's response here for what this does - http://forum.xda-developers.com/showthread.php?t=519495)
d. Flash new ROM
e, Flash Google Apps (you can also wipe cache and Dalvik cache between d and e)
9. Now the moment of truth. Reboot. Wait. This can take some time, so don't fret if it seems to be taking too long. I'd say if it's over 15 minutes then you might need to worry, but chill before then)
10. When it does boot, you'll basically have a fresh, new phone. You'll need to enter your Google account and follow all the usual stuff you did when you first got your phone.
11. Leave your phone alone now. You can click around, but don't install anything new just yet. I've seen many a post about letting things settle. So, maybe, poke around for 15-30 minutes just to see but don't change anything. Then Reboot
12. Now reinstall Titanium. You can start reinstalling your apps. DON'T reinstall standard apps or they could break (e.g. email app or its data) as the new ROM might not support the old version of the app. My rule of thumb is don't restore any data I can get back from my online accounts (Email, FB, G+, Keep, etc.). All of your pics and that should be on your SD card and should not need to be restored.
13. That's it. If you enabled a scheduled backup in Titanium you might want to disable it for a while to make sure you like what you have. That way, you can go back if you don't like it.
Hopefully that helps someone. Please forgive any mistakes or omissions and if anyone with more experience wants to give it a once over I'd appreciate it.
Thanks and good luck.
Sorry guy, but on step one there is a very high probability of someone bricking their phone.
Why? Because it has happened about 100 times over the past two years from people using that site/method. If you flash the wrong kernel you kill your precious.
You should edit your step to say in the strongest terms triple check your operating system and get the correct kernel.
And step one is unnecessary because all roms here are already rooted.
1. Flash TWRP using pc and Odin.
2. Download new rom.
3. Boot into recovery.
4. Wipe cache, system, data.
5. Flash rom. Boot and wait 10 minutes.
6. Check settings for networks.
7. Optional modem flash.
Only wipe that's needed is a factory reset within recovery. That wipes /cache too. The dalvik cache resides on the data partition and is thusly wiped as well.
The Rom will have a format /system line within the updater script.
And within titanium backup don't backup or restore system settings (anything in the list that's red.)
And as said rooting first isn't needed unless you've been using stock for awhile and have apps you'd like to backup first... the easiest way to root is simply flash the latest twrp with Odin.. boot into recovery... then when you go to reboot the system it'll see that you're not rooted and ask if you'd like to do so.
Thanks for the feedback. Like I hope I stressed, this is the method that worked for me.
I guess I have the terms mixed up in 1. I'm saying to install ClockworkMod (or TWRP) and root your phone. I want to root it here because I want Titanium installed before I change ROMS so I can go back to exactly how everything was before modding if I want. Does that make sense?
Also, can you tell me what's specifically wrong with the site I link in Step 1? I was on ICS at the time I think. Does it brick if you do it on JB?
I'll change the step to say to go here instead - http://teamw.in/project/twrp2/96
Is that better?
Also, can you explain your cache wipe suggestions. I've seen the official instructions say to Reset, then Wipe Cache, then Wipe Dalvik. I know the last 2 are included in the first, but why are we explicitly asked to do them again? Why do you think we don't?
My thinking behind adding it here is that it does no harm and if some devs think that not doing it will cause problems then why not include it to be extra safe.
If you wanted it back to the way it was before modding anything then you could flash a custom recovery and do a nandroid backup before rooting at all.
Titanium backup needs root. If you want your app data after flashing a rom then that's when it's needed.
As far as extra wiping... putting your arms over your head spinning in a circle while chanting a manta does no harm either and is just as effective.
When you flash as often as I do... you wanna streamline the process. Extra anything is just that... Extra... and is just a waste of time
His first step is correct. No one that I know has bricked their phone using those directions because that link does not install any kernels. And it never did. It works for all versions of android. Even after all this time there is so much misinformation given.
Studacris's help is as good as gold though. He has put me in my place in the past.
Thanks Everyone.
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).
