[Q] Change rom question - Nexus 4 Q&A, Help & Troubleshooting

I have a nexus 4, which unlocked and rooted standard android on it.
I have backed up my apps with titanium and backed up the rom via TWRP.
My question is if I change to a different rom using ROM Toolbox, will I be easily able to restore my apps from the phone or do I need the backed up elsewhere, does all the phone content get wiped?
Related to the above can i restore my existing rom, easily if I want to go back to it?

You do not need to wipe (format) your internal SD card so all your data will still be there (songs, pictures, apps on which you have performed backup on via titanium etc).
You should be able to restore your apps with titanium but sometimes there are apps that cause some problems.
And sure, you can go back to your nandroid backup (your old rom) at any time with TWRP.

Thanks for the advice.
So if I use rom toolbox, I just download and install a rom as zip, but do not wipe anything, is that correct?

When flashing a new rom

I know you should make a backup. So when you wipe and flash a new rom and kernel, do you restore data and that will restore all the programs you had prior at the time of the backup?
Thanks.

If you do an advanced restore of your data through CWM recovery, yes it will restore all your programs and settings. However, this can cause problems as the old data does not get along with some ROMs.

So it is best to just reinstall programs?
I would use Titanium Backup or My Backup Pro to back up you apps+data. After the flash you can either restore everything from the backup or just the data. Some people have said that it's best to re-download your apps from the market and only install the data from the backup (as opposed to restoring app and data). I don't know, I've done it both ways and have never noticed a difference.

nandroid + flashing/restoring across roms

I'm having a little trouble understanding nandroid vs. other forms of backup and would appreciate some clarification. I'm running CM nightly on my Fido (Canada) G4. I took a nandroid as well as titanium backup of the factory stock image before I flashed CM.
A poster in the last thread I made suggested if I wanted to restore to stock, I could simply restore the nandroid, but I've also seen people say you shouldn't use nandroid to go across ROMs. My understanding is that nandroid is like having a filesystem backup, which would obviously not react well if you restored it over a new operating system (e.g. two different versions of windows). Or is nandroid more like say Acronis, which takes an entire disk image and overwrites everything?
Other misc questions:
- If I do restore via nandroid, do I need to wipe all data / cache / system data before or after the restore?
- I assume I can use titanium to restore SMS + all non-system apps across ROMs, which would save a lot of time.
- If I'm going from one CM nightly to another, would titanium work for system apps (e.g. all my settings, or contacts, etc)
- If I want to flash a new CM nightly, do I need to follow the entire wipe procedure just as if it were going from one ROM to a completely different one?
Thanks!
always make a nandroid in recovery. i recommend keeping it on your micro sd card. in the event you need to return your device to it's previously functioning state, restore the nandroid in recovery. if you are running an aosp rom and your nandroid is touchwiz, wipe data, cache & dalvik before restoring the nandroid. if the backup is on your micro sd then feel free to wipe system as well.
if you want to flash a nightly or update to a rom you are currently running, simply wipe cache and dalvik then flash the update, gapps and any custom kernel that you may be running.
i cannot answer your titanium backup questions because i do not use that program

yes, that's about what I have. ok, thank you for the clarification of what to wipe! that's good to know.
re flashing a nightly/update: using your method should preserve system data yes? so no need to reinstall all apps or system data?
and thanks, I'll hold out hope that someone with titanium expertise will be able to answer that one

yes, system/user data will remain. understand, however, that if you perform one of these dirty flashes and you have a problem with the functionality of the ROM, you'll need to do a full wipe and flash to see if this clears the issue before you report the problem in the development thread.

Your right on both titanium questions.. However its not recommended to restore system apps you backed up on a aokp/aosp ROM to a touchwiz ROM and the other way around... Other than that like I said your fine

[Q] TWRP Recovery- How to use?

So I am currently on Paranoid Android and wish to switch to another ROM (most likely AOKP or PACman just to try). In TWRP recovery, what would I select to just back up my app data and NOT my ROM, and after that is possible, what must I restore to get it back and in what order of flashing alon with my new ROM and GAPPS???:silly:
You can go into TWRP and backup and choose what partitions you want to backup. However, I'd suggest you backup everything and don't try to restore the data to another ROM.
I use Titanium to backup all app data as well as MMS history, WiFi networks etc then do a full backup in TWRP. Then wipe everything and flash the new ROM. Then boot up and reconfigure accounts and restore apps + data with titanium.
It may be a little more effort but this way you can always roll back to the previous setup if anything goes wrong and you're less likely to run into any weird issues from moving data around between ROMs.
Or you could try something like app2zip off the play store to make a flashable zip of only selected apps and data which is probably safer than the whole partition. If you do a full backup first you can always rollback if something goes wrong.
When using Titanium Backup, when I hit run backup, where does it go and how do I restore it after I flash my new ROM. Or do I do the update.zip option and flash that when I'm doing my new ROM?

It goes into a folder on /sdcard called TitaniumBackup. When you flash a new rom, you will need to redownload titanium backup. When you redownload it, it will find the backups and you can click on the app to restore it.
Theres no need to use the update.zip method. Do it like this ^

Hi,
TWRP offer "nandroid backup" which is a phone backup solution, it work best to restore everything if you system data goes wrong and unable to start your phone. It also means you cannot selectively restore certain apps that you want with TWRP alone.
You can either use Helium (formerly Carbon) or Titanium Backup to backup your user apps. It will save your data so no worries here. For Titanium Backup to work, you need root. Helium works fine without root, but you need to install the desktop client.
Hope it helps.
Thanks for this tipp:
so if I make Nandroid Backup and Flash new Rom (4.3) and restore a nandroid Backup it go down again to 4.2.2 or it recover just apps / Images etc. to it?

Nandroid backup works like a system snapshot, so yes it will go back to 4.2.2 in ur case. Pictures & musics in /sdcard (/data/media) is untouched, they won't be backed up when nandroid or wiped when you do factory reset. It's an isolated zone for custom recovery.

[Q] How do I revert to stock?

I'm a newbie when it comes to all things Android. I have a T-Mobile Galaxy Note 4 which I've rooted.
I've installed a flashable zip via TWRP and I think it may be causing some problems. Due to lack of forsight, I did not make a backup.
So, how do I get everything back to stock so I can start from scratch and make a backup the right way? Can I use the factory reset option in TWRP?
The zip I flashed was supposed to unlock my wifi tethering, but it didn't work. I think it altered some system files.. If I use TWRP which boxes would i want checked?
Reflash stock rom of your device. It will be back to complete stock with no root what so ever

Factory reset does not help to revert back to stock.
Install Phone INFO ★Samsung★ app > Menu > 'Firmware Browser' to find and download stock firmware for your device.
Then boot into download mode and flash via Odin software.

Just checked it out on the Play store; looks like it redirects to sammobile for firmware downloads. I already tried to download my firmware via sammobile on the PC and it seems like the link is currently broken. However, I found it over on samsung-updates. Hopefully that's a reputable site as well.
My plan is to re-flash with stock, re-root, install TWRP, and then immediately make a backup. Is that a solid plan, or should I use titanium backup before/instead of TWRP backup?
Also, are the default options in TWRP backup good enough? Is Titanium backup redundant if I use TWRP?
A TWRP makes a full backup of the ROM, so its more useful if you mess up and its is highly recommended you make one.
Titanium Backup is useful if you wanna change ROMs, but keep your apps and app data

So for example, let's say that I want to install some mods on top of the stock firmware (like this one that supposedly unlocks my wifi tethering). But then I change my mind and I want to revert back to stock -- I can restore my TWRP backup to revert back to before the mods were installed (with default backup options checked?) and then use titanium backup to restore my apps and app data?
What exactly happens if I back up with TWRP using default options and then restore? What will be different? I'm assuming that all of the apps that I installed since the backup will no longer be there?

Yep you are correct! Restoring the TWRP backup will restore the ROM, data, apps etc that were there when you made the backup; you can, however, use TB to backup any apps or data and then restore them when you restore the TWRP backup

So, I just re-flashed the stock firmware and all of my apps are still there. The recovery mode went back to stock so I put TWRP back on. Then I rooted again and TWRP was gone again! What is going on..

In short, TWRP creates a backup of whole partition, e.g system partition - where Android OS is stored, userdata partition - where user data is stored (including all installed apps and their data, settings), etc...
While Titanium creates a backup of individual apps inside the userdata partition.
