Sorry if this has been covered way too many times but I want to make sure.
I have rooted my phone that was running 3.20.502.52 with the AAHK so now I'm on the version it sent me back to and I have done nothing since. I am getting ready to switch to the Jellytime R29 ROM. I know to make a Nandroid backup but I was a little concerned about getting back to the state my phone is right now should anything go wrong or if I don't like it, go back. It seems that I can't just restore my Nandroid through CWM without flashing a different kernel since I'd be coming from a JB ROM.
My current setup is:
Android: 2.3.3
Sense: 2.1
Kernel: 2.6.35.10-gd2564fb
Software 2.47.502.7
So, in order use my Nandroid in case the Jellytime messes up, do I simply have to do a factory reset, and wipe cache, and dalvik-cache (this is considered a "full" wipe, yes?) and then flash a compatible kernel then restore my backup? And if so, can I find that exact kernel somewhere to flash or is there another one you guys can recommend me to use in my situation? OR, can I just straight up restore the Nandroid since the backup should cover the kernel too?
Sorry I'm a newb. I'm trying to learn. All help is greatly appreciated. I'm hoping to flash Jellytime as soon as I know how to recover from it.
1. Welcome!
2. The kernel is included in the backup. You also don't need to wipe anything; just restore the nandroid. Make sure you use a fully updated recovery; make sure using ROM Manager for CWM or the 4ext Updater or Play Store app for 4ext.
3. A full wipe is system, data, and cache. Dalvik is already included if you wipe those. A factory reset only wipes data and cache, leaving system unwiped. In 4ext just choose "wipe all partitions except sdcard."
Alright. I already flashed Jellytime a while ago and so far I see no reason for wanting to go back although I did a quadrant standards test and scored lower than stock. Not sure why, but either way, this was a nice first ROM. What I wiped in cwm was the reset, cache, and dalvic. So far everything is working if I missed anything.
Didn't know wiping wasn't necessary for using backups. Must of missed that in my reading. Thanks though. I'll become less of a newb over time.

Hello,
I flashed CWM and did a full system backup/system wipe/cache wipe then installed xboarders 1.2.2 rom for the first time. I'm rooted! woohoo! I want to install eaglesblood new rom now. My question is when installing a new rom is it recommended to do a full backup or is one time enough? Thank you for any help as I am a newbie at this.
I always keep at least one or 2 backups of setups that I know work. That way if I screw something up while tinkering with my phone I always have a working backup to fall back on.
So yes, its recommended to keep a good backup on hand. You don't necessarily need to backup every time though. I just make sure I backup my texts before I flash anything. I hate losing those.
What you DO NEED to do EVERY TIME you flash between completely different roms is do a full wipe before you flash the new rom. If you're only updating to a new version of the same rom then a full wipe isn't necessary.

Thanks for your help! Also, when doing a full wipe do I need to do a dalvik wipe as well in the advanced settings in CWM?

I always do. It certainly wont hurt anything if you do. Just remember the first boot after clearing dalvik cache usually takes a little longer than normal because the phone has to rebuild the dalvik cache. Don't panic if it takes a few minutes even to boot. After the first time it wont take as long.

This is not a "how to root" post.
I finally said F it and installed clockworkmod and flashed a ROM but I just did a basic one to get my feet wet.
My basic question is how do ROM upgrades get installed. Say I install the latest EaglesBlood ROM and there is an update for it. Do I have to do a complete data/cache clear and re-flash with the newest ROM or is there some sort of updater or is each developer different?
Thanks.
That really depends on what was updated. Most of the time if you are upgrading to a newer version of the same rom, you can get away with just flashing over it, and keeping your data intact. Clearing /cache and the dalvik-cache is recommended. However this is not always the case. Some changes require data wipes to be effective. Usually best to ask in the rom's thread if a wipe is needed.
Also, sometimes you can just do a nandroid backup, install new rom, then reboot into cwm and do an advanced restore just restoring the data partition. Again, it really depends on the rom, and what was upgraded.
Hi. I've been using a ROM for the last little while (SlimICS), and I like it, more or less. There's a feature in another ROM (ParanoidAndroid, per-app density), that I'd really like to try out, but this ROM also has a lot of features I don't want (tablet mode) and doubt I would like. I use TWRP as my recovery...if I use TWRP to make a backup of System, Data, Boot, Recovery, .android_secure, and EFS, will I be able to flash this other ROM, then restore the backup to go back to my old ROM after I play with the new one a bit? Will the backup of these items bring me back to exactly how it was before, if I do a Wipe Cache/Dalvik Cache/Factory Reset?
Sorry if these questions are answered elsewhere, I'm just trying to make sure that my limited understanding of all this isn't incorrect, in my specific situation.
If you make a backup through recovery, when you restore, it'll be exactly where you left off, settings and all, when you shut the phone down.
When backing up in Recovery, you are backing up the OS and apps. This is called a nandroid. This does not backup anything on the sdcard.
Yesterday, I flashed a different kernel version on my NS. Before flashing, I did a nandroid backup using Reovery. Unfortunately, the kernel failed to load properly and I was stuck in a boot loop. I restored my backup I have done previously, and my phone was back where it was, few minutes before. It is very easy to do and backups/restores and verified using MD5 checksum.
Keep in mind that some apps put stuff on the sdcard. So if you flash your phone to a new ROM, upgrade apps and then go back to another ROM, it is possible that some apps won't work anymore. I've never seen this happen but this is a possibility.
I came from ARHD 1.2.2 and wiped cache, data and delvik and flashed to OpenSensation 200121007 with 4ext. and gapps 20120429.
all is well except Play won't restore any apps. Not looking forward to a one by one.
Any suggestions for an easier fix?
Tried removing my settings/acct and adding in Play. Finds my apps, but that's all.
Should I re-flash CM9, then gapps, then OS, then Bricked?
Yes also before flashing did you wipe data factories reset after wiping cash and dalvik? Make sure you have nandroid backup incase something goes wrong. Steps, wipe cash, wipe dalvik, wipe data factory reset, flash Rom, flash gaaps , see if that solved your issue. Hopefully it will. Best of luck. Before flashing Rom in 4 ext I always wipe data factory reset along with cash and dalvik for a clean install. Hope this helps. Best wishes .

Darn the Luck ! ! ! No change. I did from scratch.
Guess it's a one by one.
If you have nandroid, restore nandroid, use titanium backup to backup all apps, install new ROM, Gapps and restore from titanium backup.
While you are at it, I'll suggest try CM10.

I do have nandroid, bur I figured the last time I tried OS it was unstable so I didn't use the nandroid.
Is CM10 stable with OpenSense 1007, WiFi calling and tether?
Perhaps you can answer this.
Some suggested that TWRP was a better recovery. I tired it with the todays re-flash and still have these (gapps) issues. But it seems to have overwritten 4ext though it does use some element of 4ext based on the progress log.
Is there a way to delete TWRP and just go back to 4ext?

CM10 is quite stable not sure how it compares with Opensensation. Bruce CM10 is getting updates almost every other day. I asked you to try because since you are between ROM's you can get a feel of what CM10 is and how it works out for you.
Wifi calling , I don't think works on any AOSP/CM based ROM. Tether I've never used so dunno again. Check CM10 forum.
I think you can install 4ext on top of TWRP to replace it.

WTH, I'll try another. So far (knock silicon) OS is pretty stable. I think I didn't properly wipe the first time I tried and/or this kernel is better.
WiFi and Tether do work with AOSP (pretty sure OS is AOSP derived).
4ext simple wouldn't reinstall over TWRP2, although it doesn't appear that TWRP is making some use of 4ext "routines" somehow.
Since OS is stable, I'm good.

That happened to me when I changed my hboot by way of upgrading the firmware and my phone got a different android ID. I think titanium Backup gives you the option to restore the latter id number if you run it just when you are starting to setting up your phone. I didn't know that so I ended up installing one by one but gave me the chance to discard the ones I wasn't using

Hi
I have a couple of questions, been digging around xda and the web and found some conflicting answers...
1) Does a Nandroid backup also back up the kernel? I'm thinking about dabbling with some custom kernels, but don't want to potentially mess things up as well as have an easy way back to the stock kernel if I don't like the custom one for one reason or another.
2) What would happen if I made a Nandroid backup from recovery, did a full wipe (/data, /system, /sdcard, caches), rebooted then restored from the Nandroid backup?
I'm still pretty new to all this but I've done some reading and a wee bit of flashing & rooting on Nexus devices and the HP Touchpad. I also have an old TF101 that I'd really like to tinker with as well.
Thanks!

I don't know much about kernel but I do know that Nandroid backup backups everything exactly where the phone is.
That means if you do factory reset and restore Nandroid backup it will restore everything from the day you made the Nandroid backup.
I hope it clarifies everything.
Let me answer your questions.
1. When you do a nandroid backup, it backs up everything. Including the kernel.
2. If you nandroid backup, factory reset your device then restore your nandroid backup. Your device will return to the same state you had it previously. You will have all your content, files and settings. However if you do a backup, then factory reset and reboot, your device will be wiped of everything but it will boot up. As if the device was just turned in upon purchase. Also note, if you do a backup, then wipe your device (factory reset) you will not lose your backup.
Just note, if you ever flash a ROM, even if the developer states there is no issues. MAKE A BACKUP, sometimes things go wrong.
Happy flashing

Thanks for the quick replies!
I was a bit confused about 2) because I read somewhere that if you make a nandroid backup of a stock ROM, then install a custom ROM (non-Stock based ie CM, PA or OmniROM) you must flash the stock ROM again before you can restore the nandroid backup, or else restoring the nandroid backup will not work. Is this true?
Consider the following example, say I:
-flash TWRP on my device and root
-make nandroid of stock, rooted ROM
-wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push a non-stock custom ROM .zip file and flash the custom ROM
-decide I want to return to stock, rooted ROM after a while
-Boot into TWRP, then wipe /data, /system, /sdcard and caches and reboot back into recovery
-ADB push my original stock, rooted nandroid backup to /sdcard while in reocvery
-restore nandroid backup
What would be the outcome of the above example? I'm very curious...but I'd like some advice before attempting something like this myself as I'm still kinda new to all this
BTW I'm now comfortable flashing back to stock using fastboot and the google facotry image to restore a Nexus device so I now know how to do this in case things go south. I'm just curious if this would work on a device where returning to a full stock state isn't so easy.
No you don't need to install anything to get back to the previous state. So if you had a stock rooted ROM, then backed it up. But you decided to flash, let's say. Cyanogenmod but you wished to return back to stock, you don't need to flash stock ROM, all you have to do is just wipe data and restore your backup.
And for the example.
The outcome would be, you would be resulted with a stock, rooted rom.
