[Q] How do I revert to stock? - Galaxy Note 4 Q&A, Help & Troubleshooting

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.

"image" backup

I want to experiment with flashing different ROMs and kernels, but I would like a quick and easy way of restoring my stock 4.1.2 ROM with all my settings/apps if I need to. I tried to do this with Titanium Backup, but after flashing back to stock I had to wipe data and cache and when I reinstalled Titanium backup there was no apps/settings.
Is there any way to make an "image" of my default environment which I can then flash from recovery?
Create a backup(nandroid)
You will need a custom recovery installed, doing this will give you a complete system image and restoring it will put your phone back to the exact state it was in when you made the backup

Thanks, I have made a backup using CWM Recovery. I also selected the "create image.zip" option - I assume that I can flash that .zip and be back to the current state after playing with some ROMs?

Not sure about that option as I use quote an old recovery that doesn't have that option unfortunately, so can't help you there

Ok, I made both backups (the normal .tar and the image.zip). One more question though - the last time I flashed the stock ROM (using Odin), I had to wipe data and cache because the phone got stuck in a boot loop. If I restore from backup and have to wipe data and cache again, won't this render the whole restore useless (i.e. I will go back to default state)?

[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 ^

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.

[Q] Change rom question

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?

[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.
