Wipe data/cache question

i have learned so much on this site but there is one noob question i have to ask that i still dont fully understand... im wondering when rom developer recommends a "wipe" before flashing what are they refering too? I mean i understand wiping cache ive done that numerous times but i thought wiping data gets rid of everything on your phone? Is wiping data/factory reset the same thing? why would you want to delete everything on your phone in order to flash 1 rom.. maybe im missing something. I appreciate your replys!

Wiping data is the same as a data/factory reset. Usually when switching between roms, application data is not compatable and will cause force closes. You can usually skip wiping data if flashing the same type of rom, eg, between blur roms, aosp gingerbread, aosp froyo. Sometimes you'll still get force closes and will need to wipe data anyways. If you use an app like mybackup root, you can backup all your apps prior to flashing a new rom, and restore just the app. This will prevent force closes, but you'll love any app data. But at least your apps aren't lost/forgotten.

How to save apps when changing roms

I hate it when all apps are removed to change ROM. I want to try Nik's JB and I dont want apps to be removed whatsapp....

try Ultimate Backup Tool for non-rooted and Titanium Backup for rooted

In this case it should be enough to do a nandroid backup. You can test JB and if you finished testing, you just restore your old stuff. The JB ROM is amazing but it's not a daily driver yet so it's kinda needless to install all your apps on it

I backed some using titanium but how how to restore them?
What about the backup and and restore on the recovery? What is that used for?

After backing up with titanium on your old rom
Download titanium on your new rom and you can re-install, but beware that restoring data from different roms may cause FC's

Can you set Titanium to only restore the apks, no data and cache? That should avoid most issues I suppose?
The interface is a little ... busy... so I havent really given it a go yet.

Buy the premium version of titanium backup then you can batch install apps instead of installing one at a time.

Yep. What I usually do, is go on the batch section click restore app, and choose app only. And then use app+data for my games, so I don't lose my scores and saves.

You could always restore the data partition from your old ROMs nandroid backup. Works for me.

For rooted phone, I'd suggest Go Backup.
Titanium Backup is much more powerful, but some essential features, like batch backup/restore, require paid version. And it loads pretty slowly on my Incredible S.
Go Backup offers backing up both apps and their data, as well as SMS/call log/contacts/wi-fi access points. Go dev team has recently added backup merging feature, which works fine either.
Today I installed 4.1.1-based ROM from Nikhil, downloaded Go Backup from the Market, ran backup restoration and voila, in 5 minutes I got all my apps back, including paid ones.
This app is constantly being updated, which is also a weighty argument (at least for me).

I'm using 4ext, I just choose advanced restore and choose data partition.

So if I restore my ROM from a previous backup, it will restore all my apps with data too?

Thanks for the info, when Nicks new roms settle in a bit and I try them again I'm going to try your method.

Is it really the same restoring an app from a backup as from Google play? Market links work and the app is registered by the os, integrated into the share menu (facebook for instance) and so on?
Just trying to learn how android works... Something like that would never work in windows, registry entries would probably break...

Nonverbose can you please explain more about the nandroid backup. I tried titanium and it worked.
I am curious about your method.

nandroid is the backup/restore function in you recovery A nandroid backup will save your COMPLETE ROM with all apps, data and everything else. After a backup you can install whatever you want on your phone and install new things, whatever. And if you had enough, you can restore your backup and your entire phone will be just like when you did the backup It's also a great method to switch between ROMs for example your daily driver (let's say ProjectX) and JB Evolution You can configure both ROMs like you want it, do backups and switch between them The process of backing up/restoring a ROM takes about 5min.
I hope this answered all your questions

Yup I tried this one today but I didnt know it was called nandroid. Thanks

Stuck on Paranoid Android Bootscreen! (noob) HELP

Hey everyone...
ive already tried to get some quick help already but i really need my phone tonight LOL.
iam running cm9 rom with the latest cm9 stable kernal, now i wanted to flash the hydrocore kernal to see if battery would improve, but it seemed fine but then choppy afew hours later so i changed back to cm9 kernal. Anyway after it rebooted it stayed on the paranoid android bootscreen! where you see the picture loading. i then tried to wipe the cache and dalvik and its still stuck. someone mentioned to do a wipe but i was unsure if he meant to a full wipe? as ive not wiped the factory reset, just the two caches! ive also flashed both kernals back and forth and im still stuck.
Its a simple issue iam sure but could someone help me, im unsure if i should do a full wipe including factory reset or just flash the cm9 rom again. if so can i have instructions step by step...
thank you.

islandmixed, you are on a safe kernel so there is no harm in performing a wipe data/factory reset.

A full wipe worked, it rebooted. since iam weiry about restoring my apps again via mybackup pro i might just check all my apps installed from google and install them one by one and then that way i wont have to worry about anything going wrong. i do have a backup from TB and mybackup but someone said it can cause issues when restoring to a cm9 rom!
Thanks for the help. iam back again at the start HEHE.

You know when I wiped data would it have wiped off the gapps? I'm sure I had more rom apps with this....hmmmm
Sent from my GT-N7000 using XDA

wipe data is totally wiping what's in your phone.. including what's inside the system/apps, build props and framework...
you may need to flash back your g.apps if you want to get all of them and selectively selecting which to install back(rather than just restoring it from TB)
TB does not restore all what you have made a backup to.

Okay then I guess the factory reset only deleted user apps then. I was told it deletes system apps which is why I thought it deleted gapps.

[Q] Stupid Question

I've rooted my phone and I want to get the new MaximusHD ROM (4.3, HTC Sense, Rooted)
How can I replace my ROM while preserving my data (WhatsApp messages, pictures, etc)?
I am sorry but I am coming from the world of Apple and iTunes did everything for me. Android is a totally new beast!

What do you mean by user data?
Pics music videos etc, basically anything in your SD card will be saved.
I think.
App data, you need to backup the whole app. That's how Ti backup works. You can't download the app form play store and apply your user data to it.
EDIT: just make a nandroid. Then backup whatever you need. If the restore fails, then you have something to fall back on.

Go to TWRP (personal favorite) or CWM.
Then, back up EVERYTHING.
Except media. But I'm not sure that's actually an option lol.
Oh yeah no need to back up the cache or the recovery either.
I believe CWM doesn't let you choose, you just hit back up and it backs up what it needs to.
Note: you can not selectively restore from a nandroid very easily. It is meant to be sort of a time machine, so if something screws up, you just restore your phone back to how it was.

Yeah, TWRP lets you back up all your info. You can pick and choose and it lets you back up the current rom, so if you have issues you can go back to it. Copy that folder to a computer, because what you want to do is a dirty flash and might run into problems. It's best to flash by wiping clean and then replacing or you run into problems with the rom with some of the data.
Just my opinion.

My advice would be to read a lot more about how nandroid backups work and about how backup apps like Titanium Backup work as well before trying anything.
That being said the above advice about doing a nandroid from recovery is a must, especially if you're new to the android world and aren't sure what you're doing. The nandroid is your fail-safe in case anything goes wrong. It will allow you to restore your phone back to exactly how it was when you did the backup.
As far as bringing the app data that you want into your newly flashed rom, this is what I do:
1. Have a rooted device
2. Download Titanium Backup (I bought the pro version, I think you need it to do batch backup/restore)
3. Batch backup all user apps (I also backup my call log and sms/mms messages)
4. Reboot device to recovery and perform a nandroid backup
5. Flash new rom
6. Wipe data/Factory reset
7. Reboot into new rom
8. After doing all the initial device setup (google account, etc.) install Titanium Backup and restore all missing apps NOTE: RESTORE ONLY THE APPS NOT THE DATA!
9. Now this is the part that I do that technically isn't recommended because restoring data can cause issues but it's the only way I've found to restore app data that otherwise can't be restored. Do a batch "restore all apps and data" but select "data only" and "deselect all" and go through and manually select only the apps you really need to restore the data (this can also be done manually through Titanium but I still use the batch function). Also I restore the call log and sms/mms at this step.
Hopefully this helps. Best advice I can give you though is before you do anything, make sure you understand all of the steps completely. I've lost everything too many times because I didn't know what I was doing.

Question:
Why can't he restore apps and data together? I've anyways done that, and it's seemed to have worked for me. Maybe I just didn't notice any lost data?
Also. Restoring with the free version is a pita because you have to give it permission for every app individually.
Just saying.
And you do not need to wipe your media, but I recommend that you back it up.
Also: WOAH WOAH WOAH. Did you just tell the OP to flash a ROM, THEN wipe?
I'm pretty darn sure you should not do that.

The reason I say not to restore data for every app is that not every app needs it's data restored to get everything back (i.e. Google Hangouts, Facebook, Twitter, etc.) and I've always been warned that restoring data can cause issues. So my reasoning is the less I restore the better.
And I know using the free version of Titanium Backup is a PITA, that is why I said I use the paid version.
I never said to wipe media (I assume you mean the virtual sdcard) I said to wipe data/factory reset (the name of the option in CWM)
And there is nothing wrong with wiping after a flash. The wipe gets rid of user apps/data, anything installed with the rom is fine. If I'm mistaken, I apologize. However, I have never had an issue wiping after a flash.
If the OP doesn't want to follow my advice that's fine, I was simply describing what I've been doing on various devices for the last couple of years.

Issues with backup/restore corruption

Every single time I go to upgrade to the next version of the dynamic kat rom, I can NEVER restore the data that i back up. I always end up in a loop where the apps attempt to sync and then the phone hangs and force shuts down and restarts. Yes, I have researched this for many hours before asking but I am still at a stand still.
I've heard this can be an issue with an offending application, but I really don't know what I'm supposed to do about it if I don't know what app it is, and I don't download anything broken, of course I use some cracked paid apps but would that cause errors?
It's a t-mobile galaxy note 4 running dynamic pop 6.0 for COD6. Android 5.0.1, baseband COD6. Kernel is whatever came with the rom and the phone is rooted. with knox definitely tripped.
I'm pretty technology proficient, so I'm hoping I can work with someone to figure out the root of this issue to finally fix it once and for all so I can upgrade without having to constantly fix soft bricks and manually transfer data and customizations over.

Give these options a try the next time you backup your ROM using TWRP: Boot, System, Data, EFS, Modem. I have had zero issues restoring a backup (using TWRP) with these choices.

No issues with TWRP here either. System apps don't matter for TWRP, I thought you were talking about restoring apps from titanium Backup.

Okay will do, I really hope I don't get completely wiped this time and stuck in a soft brick. The phone definitely needs to be updated, plenty of slow downs and weird bugs happening which I assume is because its one of the first releases on android 5.
The issue I'm having is specifically occurring when the apps are restored/updated/synced initially right after a restore. The phone hangs and force restarts and is stuck in a boot loop.
Restoring system, boot, efs, and modem won't cause conflict with an upgraded ROM? Like going from kit kat to lollipop?

I have similar but maybe different problem, I made 3 different nandroids with 3 different roms and cant restore anyone of them It give me errors so restore never completes but already formated system so I have to Odin from start. Using latest twrp, also after odin and installed new rom cant restore apps from tibu backup. If I try to restore only a user app, (never system) the restore option is disabled. And batch restore shows 0 missing apps but you can see the backups are there. Im gonna try in nandroid efs and modem, didnt do it but Im nervous the same its gonna happen.
Thanks

Make sure you are using the right path for restoring in TiBu. Go into menu, preferences, backup folder locations. Make sure you see your backups.
Also try menu, refresh apps list.

Im a user of Tibu and lots of flashing roms for 3 years in different roms never have this problem Im getting with my new note 4.
Right now Im trying to make a nandroid and its stuck backing up system for like half hour I dont know if take battery to end it.
