Nandroid backup - Galaxy Tab S2 Q&A, Help & Troubleshooting

Questions,
1)
For a Nandroid backup I do not need *root*, is that correct?
TWRP should suffice.
2)
What are my options to forestall any possible Samsung OS update, OTA updates included?

1. If you update via OTA i.e. Update center, you will retain everything and system will be updated.
But if you flash the. 67 ftf you can still uncheck wipe data, app etc. to keep your data.
2. Without root you can use PC companion or backup app from sony... But 4.1 backups won't work on 4.2 but surprisingly 4.2 backups work on 4.1 too (it worked for.me when I flashed 4.1)
I think an app called "helium" can backup without root but I haven't tested it.
Your best bet will be to root and use Titanium Backup.
3. Savinh your Rom stuff can only be done via CWM recovery which can be installed after root. However you can make backup by sony's app and flash old ftf to rollback.
4. Haven't used the pc companion backup but the backup and restore app works perfectly. You can save the backup externally by copying the. semc-fullbackup folder from your chosen location of backup.

[Q] Need help updating to Sense 6 with TWRP

Hi, I used TWRP and the official tools to root my HTC One M7. I just received today an official download of the Sense 6 update and it asked me if I wanted to update. I clicked "Yes".
Now the phone rebooted and went back to the TWRP screen, and I don't know what to do to update my M7 to the Sense 6 platform. What should I do?

To run the update you need the stock recovery for your version of the ROM. Install the stock recovery like you installed TWRP. Depending on your version, there may be some preloaded apps that are missing due to rooting. Prior to flashing the stock recovery, make a nandroid backup and save it to your computer. If you want to start the OTA process over again, you must delete the OTA (Update) file from your download folder.

What is a stock recovery?
This backup you call is just copying all the files to my computer and pasting them over after updating?
What is OTA?
Does this mean that if I update to Sense 6 I'm not going to be able to use AppOps anymore (the sole reason I've rooted my phone)?

Stock Recovery = The recovery that comes with your ROM version.
Nandroid Backup = While in the custom recovery (TWRP) you can backup your phone's data, rom, cache, firmware, etc by selecting the backup tile. This is called a nandroid backup. You can restore it by selecting the restore tile. A nandroid backup is more complete than just copying the files from your phone. You should do both.
OTA = It is the Over The Air update to your phone.
If AppOps runs on Sense 6 then you should not have a problem. I don't have the app so I can not tell you one way or the other.

OTA with a rooted device?

Hi everyone, it's been a while since I started thinking to root my Moto G 2 but I still want to run on stock kernel & ROM. We are still waiting for the update to Android 5.1 and I was wondering if I could get the OTA safely with a rooted device. If not, I would wait for the official update and after this I'm going to root it; otherwise I would root it now. Thanks in advance.
I think you should wait for the OTA update and root after the update.
You won't receive any OTA updates from Motorola if you have flashed custom recovery and rooted your device
Copy that, thank you guys.

If I understood it right, @luke! wants to run stock rom after rooting. So there is absolutely no problem to boot into TWRP 2.8.5.0, make a nandroid backup and flash latest superSU from there. OTA just cares about custom recovery and changes in system. So when an OTA arrives just restore your nandroid backup or revert the changes you made like unfreezing systemapps, uninstalling things like adaway and there will be no problem to install OTA.
Even if you flash twrp instead of booting into it,you can easily flash back the custom recovery. As long you stay stock this is all an easy thing. And also after flashing a custom rom there are ways to get back to the original firmware. @luke!:If you need any help pm me.

Rooted Stock Major OS Upgrade

The Nexus 6 was my first Nexus. Since I am unlocked, rooted, stock I have been using the factory images to update throughout the life cycle of lollipop. Flashing all but User Data. I have never updated through a major OS revision before.
With 6.0 possibly being released today, would it be ok to dirty flash from the latest 5.1.1 to 6.0?
Probably, though a rooted user should take a nandroid backup and titanium app / data backup too in case a wipe is needed. A Wipe is always best when upgrading a major OS version
Thanks, I do have a nandroid backup and Titanium app/data just in case a full wipe was needed. Just was curious if I should even attempt a dirty flash.
So I am guessing there is different code in an OTA as opposed to the Factory Images to safely migrate settings?
An OTA doesn't do anything special to "migrate data" at all, if you look at the scripts.... and it's for this reason that if I received an OTA ever, I would wipe (Though I've never taken an OTA in 5+ years)...
You can attempt it, yes. I Believe you can flash the preview 3 without wipe
Hi, dirty flash (manually fastboot flash.... everything except user data) worked fine for me, from LMY48M to MRA58K.

ANCIENT Android

I have quite an old version of Android on my Nexus 6 (see attached). Is it safe to flash or fastboot to a 7.0 or 7.1 build without wiping? I am on rooted Project Fi. I don't necessarily need to keep root (though I prefer it for tap-to-wake), but I do need Project Fi compatibility since that is my carrier. Thank you!
You are going to have to wipe data and cache, flash bootloader and radio, and then you are clear to go to 7.0 or 7.1! *project FI is not a custom rom thing, its going to work now with any rom! Root is as easy is reflashing SU when done with upgrade, if you want root again.
While you probably can receive OTA updates until you get to Android 7.0, there's no guarantee that you'll get the required updates. Flashing one of the OTA images from the Google Developer website will get you there a lot quicker. But you want to back up your internal storage onto your PC before applying the OTA. Since there is a bootloader update involved, your device may end up wiped.
Darn. Can you link me to whichever bootloader, radio, and build would be best for me to use? I just want the base stock Project Fi build, so I'm not sure if I should get the Google build, or one in the dev forum.
I cannot utilize OTA updates: I click install, it reboots, and fails. Hence why I have been on 5.1 for years. I just haven't had the time (or desire) to do all of this manually. How should I go about the upgrade process? I understand the process of fastboot and all that (though it has been a while), but I need a little guidance on which file (or files) to use and where to download them. Any pointers on which website and which download(s) would be much appreciated, whether it is the official google file, or I need other files as well, etc.
This is a link to the 7.0 bootloader and radio, both flashable! http://forum.xda-developers.com/nexus-6/development/fxz-nexus-6-recovery-flashable-fastboot-t3066052
This is a link to a stock (project fi ready) 7.0 build, with radio / bootloader/ rom / gapps / everything. Perhaps it would be easier just to do this writeup! http://forum.xda-developers.com/nexus-6/general/android-nougat-nbd90z-flashable-image-t3474572
Excellent thank you. Regarding the second link:
a) This will work for 5.1 and a very old version of TWRP correct?
b) Also, what is the purpose of making a backup if this will wipe the storage anyway?
Of course it fails. OTA updates require the stock recovery to work. Had I known you had TWRP installed I would have had you flashing the factory image using fastboot.
a) no, while it may work, You should definitely update your version of TWRP
b) You aren't going to wipe your internal storage if you use TWRP. that's only when you're flashing via fastboot
If you use TWRP, you can wipe the system, data, and cache without touching your files. just dont' wipe internal storage
Yes. I do have TWRP. In that case, do you agree with the other post that the following link is the best upgrade path? http://forum.xda-developers.com/nexus-6/general/android-nougat-nbd90z-flashable-image-t3474572
Ohhh I see. My eyes immediately skipped to the "Method 2" content.
a) So I should first update TWRP, and then perform "Method 1" in that post, correct? Just want to make absolutely sure of the steps.
b) In the case that Method 1 is correct, since my data would remain, will my phone be wiped or not?
Yes.
It worked! I am now proudly on 7.0 without wiping!!! Thank you!!!!!! How do I mark this as the answer? Woohoo!!!
P.S. In case this should help anyone else (or maybe help myself in the future), I updated TWRP though the "TWRP Manager" app, did a full backup of the phone (took 822 seconds), then flashed that zip in that other thread. So far so good!!!
Woot!
