[Q] Backing up before flashing rom? - Galaxy S 4 Q&A, Help & Troubleshooting

Hi, I want to flash WanamLite ROM to my new Galaxy S4, but last time I flashed WanamLite without backing up I ended up with a generic IMEI, so I need a way to back up my phone and IMEI and all the other important stuff, I can't afford Titanium Backup PRO right now, any other way to backup my phone so I can restore it in case anything goes wrong?

Once you flash a custom recovery like twrp or cwm you can backup your efs folder, you should keep that folder somewhere safe. After that you should make a nandroid backup and also keep this safe incase you want to go back to your stock rom
What I also like to have is my stock firmware on my pc so if anything goes wrong I can flash the stock fw
Edit: you can also backup efs manually but I am not informed about these techniques so I cannot tell you

I'm already rooted, can I back up the efs before I flash the rom?

There are various efs backups on play such as this although I haven't used them to restore them personally

If you're already rooted then you can also just flash a recovery with sgs4 flasher from the play store. Really nice for keeping updated. Backup efs With the custom recovery, or as the person above me stated, use an app for it

[Q] Can I restore to rooted backup after flashing rom?

I am using clockwork mod touch edition, and I have a full system backup using it. If I decide to flash cm9 to the device and then decide I want to switch back, can I then restore to this backup using cwm? Or do I have to flash to a stock Rom first?
Brent
u can restore using the backup u created earlier
Ok so the restore also includes the Rom backup then?
yea, that is the main purpose of recovery
Cool, thanks. Just trying to understand more about what is happening when I do these things. Cheers!
don't forget to wipe cache/dalvik cache. u should be fine

HELP!!! :'( Restore only apps and data from nandroid?

Hey guys!
So yesterday, I installed the app 'Android Control Center'. I messed around with a few settings and ended up in a bootloop. I do not have anything backed up in Titanium backup. So I made a nandroid backup in the hope that id be able to restore my apps out of that by using nandroid manager, but all of my app data were not extracted from the nandroid. So now im planning to restore the nandroid backup and use TWRPs file manager to remove that apk and its data. Are there any other things I should do to fix this problem? Will this work??
Guys, any help is appreciated!!!
Hardly believe that app can cause your system into bootloop... anyway, if you want to try.
Titanium Backup can restore apps from Nandroid backup, preferably CWM tar backup. However, this function is currently having issues with Android 4.3, so if you want to reflash the ROM, pick ROM with 4.2.2.
I believe TWRP backup should also works, but I haven't try it before. If you need to use TWRP, do it without compression & encryption.
IMO your problem can be a simple fix by remove the faulty app and reflash the ROM.
just reflash your rom via recovery, dont wipe, you wont lose any data
Alright thanks for the response. I copied my TWRP backup to my PC, extracted it and now I'm trying to copy the data folder from my TWRP backup to my ROM's data folder. Hopefully, this will work.
PS - I removed the app and i reflashed the rom but that didn't seem to fix the problem.

What is a nandroid backup and how does it differ from titanium backup?

I am new to this rooting world....I rooted my nexus 4 a week back using Nexus root toolkit v1.8.
I then flashed cm11 onto my phone.
I have TWRP recovery on my phone.
I want a full backup of my apps+data+ROM. How's this possible?? Which of these backups allow this..... And how to do these backups.
Also can anyone explain what a kernel is??
Titanium backup can only backup part of your data. Simply because apps can't access everything.
If you want a full backup, you should make a nandroid backup. Which is simply the name for a backup you do through your recovery. (TWRP in your case)
And the explanation of a kernel is really easy to find. So you'll have to use Google for that (I can't really think of a good explanation atm)

Just use the backup toggle in twrp. And no, you can't backup direct to your pc. But afterwards you can copy the backup to your pc. It's good practice to have at least one recent backup there just in case something happens where you'll need it.

Some More Question Regarding Backups :-
Backing Up Using The ROM Manager (By Clockwork Mod) also performs the Nandroid Backup ???
Also when I Restore My Nandroid Backup (Of ROM1) while i am using some other ROM(ROM 2) .....flash the device into the ROM 1 settings and all the systems settings+apps.???

First, don't use rom manager. You don't need it
A nandroid is like a copy of the entire os and all your apps and user settings. If your running rom2 and you restore rom1 all your settings of rom 2 will be forgotten and the ones you had in rom 1 when you backed it up will be restored.

Although this is not really accurate, but this is as close as I can get to. Think of a phone like a car. The engine part which is essential to make your car runs is your kernel while the body, doors, sidemirrors and everything else are part of a rom. Kernel is in the deeper layer of the system.

[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.

[Q] Odin or restore?

I have a n900w8 running cm11. I need to go back to stock.
I have a nandroid of my stock rom and was wondering if i can go back using my backup or if i need to use odin to downgrade?
Just want to make sure there are no issues with bootloaders etc if i restore my backup.
Thanks
Well as technically Nandroid backups are just a clone of your previous OS you should be able to flash it just fine, BUT you should not. Cause in doing that you will face several problems, multiple apps force closing would be one of them. So yes, just wipe the phone first, I mean a complete wipe, then flash a stock ROM of your choice via Odin, root, then restore apps with their data manually using Titanium. I mean the option in Titanium which says install the missing apks only, just hit on that, not the whole system wide restore, cause that will create problem too.
I don't know what model is that though, I have a N9005, so what I said might not even be applicable for your model.

Better to flash the latest stock firmware for your device via Odin.
and restore app(s) later.
