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.

this is correct
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?
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
5. restore current ROM from my sdcard using nandroid and again wipe the same caches
(same here again, wipe first then restore)
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?
i think you will have to flash gapps again
Pretty simple really. This make sense?
looks good (how sure am i? id say 80-90%. it definitely makes sense, but i have never done this before)
Good good. It's getting late so I'll tackle this tomorrow. Thanks for the detailed help... I'm glad I asked before going at it.

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.

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.
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?

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,

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.

Hi.
I have the stock rom 4.2.2 its root and a Twrp Recovery.
So i want to update it to 4.4.2.
My Problem is OTA doesnt work because, i have a boot loop i come only into Recovery.
Meanwhile im out of the bootloop.
I wanted to ask if I can update without data loss.
Thanks in advance.

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.

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.

+ 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.

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!

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

Always wipe system when going from rom to rom. The new rom will install new system stuff.. Never wipe "internal storage"!
How do I make my stock partition smaller, or remove it completely to give to my Cyanogen Mod slot?
What values would I edit in the build.prop file for a Razr Maxx with Verizon?
Thanks a lot!

1. You can just wipe stock slot and install CM on it. You have to do it fresh and not restore a backup from another slot.
2. Why do you need to edit your build.prop?

1. Is there another way to take space from the default slot and give it to the CM slot without having to reset it?
2. Because I need to download some carrier-specific/manufacturer apps that have all of my contacts.

1. No, stock slot, is stock slot... all of that is predetermined space of the partition... If you have titanium backup Pro and a custom launcher... all you will really lose is time. Make sure you are saving to ext. sd just to be safe, backup your user apps, backup again for modified data, and you are fine. For the custom launcher, save your setup. After you flash over, restore. Depending on what/how much you have it could take a couple hours... some games that require extra data, you will still have to download it but, your progress should still be there. Double check if it is a game, as some of them only save via a cloud.
2. I may be ignorant to your particular situation/apps, but, if your previous device was a an android device, and you saved your contacts to your google I.D. they should be waiting for you, when you reactivate from the wipe/flash. When I got my first droid years ago, I was coming from a crappy flip phone from att, they were able to flash my conacts from the att sim over to my new droid. All my contacts are now saved via google.. so it doesn't matter what phone I boot up.. my contacts are waiting for me.
If I helped you, hit the thanks!

Ok, I know what I'll be doing this weekend. Thanks!
EDIT:
Will everything will work out if I install CM on the stock, and then delete ROM-Slot1?

Keep slot 1 and it's backup til you have the stock slot the way you want it. That way, if you forgot something, you still have what you need til you figure out what you missed and it isn't gone for good.
When you do your wipes DO NOT TOUCH internal storage and micro SDcard... that is all your personal data.. there is where your backups are... you wipe them your screwed.. pictures.. music, all of it is gone, and no one can help you!

I've done what you've said, booted on to the stock ROM, and it's been on the CM boot screen for an hour, I still have the CM installed on stock ROM 1, what would've caused this problem?

Lol.. now you know why you wanted to keep slot 1. Either the stock ROM didn't get fully wiped, the CM11 didn't install properly, or it was a bad download.
So. Just a recap, you are using safestrap 3.65 or higher. When you did your wipe, did you just factory reset, or did you go into advanced wipe and wiped Dalvik cache, android secure, data, cache, and system? The CM thread recommends advanced wipe, and doing it three times!

OK, I am gonna just start from the absolute beginning again:
I am flashing the Razr back to factory default with RSD Lite... Complete
Booting into the stock Android installation... Complete
Rooting device with RazrBlade... Complete
Installing Safestrap V3.65... Complete
Rebooting into Safestrap recovery... Complete
Wiping ROM Slot 1 3 times, wiping the same as 2 steps below... Complete
ADB Push CM onto /sdcard/
Install and configure CM on ROM Slot 1 as a fallback...Complete
Advanced wipe Stock slot 3 times, wiping the Dalvik cache, Android secure, data, cache, and system, this is where I messed up... Complete
Install and configure CM on Stock slot...Complete
Delete ROM Slot 1... I'll delete it once I have the Stock ROM fully finished.
It works, thanks for dealing with my stupidity

Not stupidity. Ignorance (for lack of a better word... look up the true meaning if you are taking offense.)
And just so you know, you probably went through a few extra more steps than you needed too. Stock wasn't damaged, just needed to be thoroughly wiped then reinstalled. Also if you had a backup of Slot one, after you did the firmware reflash with RSD then root and recovery, you could have just restored your slot 1 backup.. same thing, less time. Just a couple of tips.
It is certainly good that you aren't afraid to just reflash a fresh firmware though, that can solve a lot more problems than you think. Hone your searching skills, and you are golden
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).
