Question: Non-root ways to do a nandroid backup?

Hi Everyone

I used to be a frequent XDA user back when I had a Motorola X2, and I rooted and flashed things to that until I broke it pretty much haha. I had an iphone for the last two years, but now I'm considering getting a Samsung S6 Edge.

I do have a question though. I want to stay unrooted (to use Android Pay and Samsung Pay) but I also miss the complete backup that my X2 used to do with a custom recovery. Can I unlock the bootloader (without root) to install a custom recovery, which wont mess with the system partition and allow me to use android pay? Or is there a better, complete backup solution for an unrooted S6 Edge ?

And I'm a software engineer, so don't worry about being too technical :D I'm very comfortable in the command console LOL.

I found conflicting info online about how to do this, so I thought I'd go straight to the source of all things new and cool for android: XDA !! Thanks in advance for the information.

What is 'persist' in TWRP while taking a backup?

hey guys, I just bought OPX 2 days ago and rooted and unlocked the bootloader yesterday. I also removed few apps like slides, doc etc and everything was working fine. Today when I saw storage was almost full (because of those google apps updates) I tried to integrate them into ROM using Titanium backup. 2 of 18 apps were successfully integrated (don't know which) but then it stuck for a lot of time. So i forced stop tit and tried integrating each app individually, but still same problem and it had f**ked system a little so fortunately I had restored the backup which I took before integration. During backup, I selected all the partitions (or whatever it is) and started restoring. Everything went well until the 'persist' was getting restored. Wiping of Persist was successful but it was stuck to restoring for a really long time so aborted the restoring, wiped everything and restored everything except persist. So my question is What is Persist and will it affect my phone 'cause I didn't restored it? and why are apps not getting integrated into ROM? any solutions will be helpful
(and extremely sorry for super-long post :P )

Howto update Pure Nexus incl. Baseband, Bootloader + Backup Apps?

Hi,
after managing to unlock the bootloader, turning off the forced encryption and flashing Pure Nexus I am very happy to have a nice system.

However I am still on version 6.0.1-20151219 and I would like to test the newest version.

What is the best way to update to the newest version without loosing my apps? After doing some research (I am a noob) this strategy seems to be the best:

1) Do a complete nandroid backup over TWRP just in case of failure
2) Backup all user apps over Titanium Backup
3) Transfer backup folders of TWRP and Titanium Backup to my PC for later use
4) Download the newest shamu stock ROM from Google and extract it
5) Start my device in fastboot mode
6) Run

fastboot flash bootloader C:/image-shamu-XXXXXX/bootloader.img
fastboot reboot-bootloader
fastboot flash radio C:/image-shamu-XXXXXX/radio.img
fastboot reboot-bootloader

7) Start recovery (TWRP)
8) Do "Wipe data/factory data reset"
9) Flash newest Pure Nexus + gapps
10) Reboot
11) Configure phone (google apps etc.)
12) Install Titanium Backup, copy back backup folder and restore all apps
13) Done

Anything I missed or something wrong?

Thank you very much for your feedback!

Japanese Rom Backup

I have an old Japanese phone, Casio g'zone Type-x. Since I have never tried to back up a rom before.

I will also need to edit the rom to get the rom to add in gsm frequencies as well, if there is a software requirement for it.

This backup is needed as I plan to change the cdma chipset to a dual cdma/gsm chipset.

So the first thing to do is backup the rom.
Secondly is to edit the rom to handle gsm frequencies.
Third once the chipset is switched flush the phone with the updated rom.

Help with this would be appreciated.
