I have an EU H870 with V20g-EUR-xx version 8.0.0 (from Settings-->About Phone-->Software Info)
I have many apps already installed with data
I want to unlock the bootloader, install TWRP, install custom ROM, install Magisk (for root), restore my user apps+data
I realise that unlocking the bootloader will wipe out my user data (factory reset) so how do I backup all the apps+data beforehand and then restore them at the end? I had an LG G4 before and unlocked the bootloader when I first got it (second-hand already out of warranty) but this G6 was quite new so didn't want to unlock straightaway. I have used Titanium Backup on G4 but it won't work on G6 as I don't have root yet so I seem to be in a loop here (need backup before root, need root to backup).
I have also heard of issues with TWRP and re-encryption issues preventing TWRP restoring TWRP backups.
Can someone help with a definitive list of instructions, listing other G6 guides is OK. I have searched the G6 Guides section and G6 Q&A section but couldn't find the full story.
I am just so lost at the moment and don't want to lose my data. I know my pictures/music are OK as I can copy them from the internal storage to an SD card and copy them back.
Thanks
Darren

Hey guys and gals!
After a few weeks of using the phone, I now feel comfortable doing a Nandroid Backup (TWRP).
I used to do it all the time on my OPO Kitkat, but now with Android Marshmallow, it's quite different.
Here is my situation:
A2017U (us version)
TWRP 3.0.2.2 Installed
Bootloaded Unlocked
Rooted
Xposed Framework v87 installed
Update B29 installed
Inside TWRP>Backup I have many options:
1- Boot (64MB)
2- Cache (2MB)
3- Data(6969MB)
4- Recovery (64MB)
5- System (3723MB)
6- System Image (6144MB)
7- EFS (4MB)
By default, the "Boot", "Data" and "System" are selected, but after some reading I could also backup "System Image" for a near-perfect restore.
Also, some said to backup the EFS in-case it gets corrupted/damage, but some say it can brick your device.
Could anyone tell me what should I backup in case I get stuck somewhere in the future.
Thank you !!
P.S: I have removed any fingerprints and set the lock screen to "Swipe" (no pattern).
First, make sure to flash the official twrp. Do not keep the one we use to unlock bootloader.
There is no harm in backing up efs, in fact it is a good idea to do so. Just do not select it during a restore unless something has wiped your current efs and its the only way to fix.
I don't see a need to back up a full system image but couldn't hurt to at least have one for safe keeping.

This? :
https://twrp.me/devices/zteaxon7.html
https://dl.twrp.me/ailsa_ii/
Edit: Looks like there's twrp-3.0.3-0-ailsa_ii Out for the Axon 7
But the official XDA Forum Page it's twrp-3.0.2-0-a2017u
After flashing the 3.0.2-0-a2017u, I now have in the backup sections: Modem (NON-HLOS) (95MB), I don't know if I should back it up.
Hello,
I have an S7Edge and looking to flash it. I am currently in Nougat 7.0 and would like to backup my data before proceeding with the root.
I have flashed the phone with TWRP but when following this tutorial: https://forum.xda-developers.com/s7...overy-official-twrp-hero2lte-3-0-0-0-t3334084
People say that you have to format the Data Partition in order to proceed with the installation of SuperSu and NO Dm verity.
Is there a way to backup my phone data [w or w/o TWRP] before ROOTING my phone with TWRP (format data partition to decrypt, install no dm verity and install super su)? This is so after my phone is rooted, I can restore all the apps, pictures, etc.
Thank you for the help! :fingers-crossed:

Dear All,
I would really appreciate if anyone could help me on the question above. Need to get my phone rooted but want to have it backed up first.
Thank you!

Hi,
Thank your forwarding me to your thread. I think I figured out a way to fully back it up with the following steps:
1) If you are in Nougat, downgrade to 6.0.1
2) Root your phone by flashing CF-Auto-Root in Odin (it should not wipe any data)
3) Once phone is rooted, you can backup your phone with TitaniumBackup or Flashfire
4) Save the backup in your sd or other external
5) Update phone with official or custom Nougat FW
6) Root phone via custom recovery (TWRP), will have to format all your data
7) One phone fully booted up and rooted, restore from backup with TitaniumBackup or Flashfire
Let me know how it goes
My Nexus 6P is not rooted, bootloader is also locked. As the BLOD is imminent threat, i want to unlock my Bootloader. But i'm unable to find any app to backup my entire phone. Personally i like nandroid backup from TWRP, but without root, it's not possible, and in order to root i need to unlock BL which inturn will wipe my /data partition. See my dilemma here?
So, if therer is any software that can backup my phone while i unlock BL and restore my data?

Just backup and sync with google it's decent now. Can't remember if internal gets touched maybe backup to computer or thumb drive to be safe.

Thanks. I decide to bite the bullet and go for bootloader unlock. You are right, google backup is now amazing, i've even got back my call log and sms. App data is also restored, but no internal Memory is backed up. luckily i did copy my Internal memory.
So, TL,DR: Copy all my internal, did google backup. Unlocked bootloader, Got TWRP then root using magisk immediately (otherwise TWRP dosent stay), restore backup. Got old phone back
I updated an old thread on this. Long story short I have another G5 plus and rooting it is going nothing like rooting the first one.
In theory, I should be able to just pull an image from the first one and use TWRP to restore it, skipping the EFS partition. I have the correct EFS backed up on the new G5 plus.
Currently the new phone has TWRP 3.2.3-1 installed and has the boot loader unlocked. I have the zip file for Magisk 16 but it is not installed. I was able to overcome many problems with the new phone booting after I tried to restore the image I wanted.
My goal is to have them both function the same.
Is it possible to use a backup I made with one phone on the other, or should I manually install everything?
Would attempting to use that backup corrupt it?
Restoring a backup from an identical phone on to a new one
shadow460,
Restoring a backup from an identical phone on to a new one. Will work just fine. I have done it before. After breaking a screen, pulling the sdcard & putting it in the other phone. And using TWRP to restore (clone) the original phone.

I have a completely stock Moto G5 Plus (XT1683 - 2GB of RAM) on stock Oreo 8.1 and I want to use the Pixel Experience 10. I've watched some tutorials online but I still have some questions:
1. I've seen many people complaining that they lost their IMEI and 4G, but I still couldn't figure out if that only happened with people that downgraded from a custom Oreo rom to a stock Nougat or if there's a chance of that happening by installing any custom ROM. My phone has the latest official Oreo version and I've never messed with the system before. Is my phone still at risk of losing its IMEI if I install Pixel Experience 10? What did those people do wrong?
2. Now let's talk about the procedures I have to take. After unlocking the bootloader it will wipe my system, right? If that's so, should I let it boot again into Android and turn off or should I immediately get into fastboot and flash TWRP? Will it make a difference? Will the persist and efs partitions be there on TWRP to be backed up or do I need to let Android boot so it can make them first?
3. After everything, if I get into TWRP and it asks for a password, should I just cancel and wipe the partitions to remove the encryption (can I keep the internal storage?) or do I need to install that dm-verity file instead? As I understand the dm-verity if only for when rooting the phone while keeping the stock system, right? (I don't plan to root my phone, only install a custom ROM. It would also be good if I could keep my files, but if I can't, that's fine too.)
My original plan was the following, please take a look to see if i'll do things correctly.
1. Unlock the bootloader
2. Install TWRP immediately, before it even has a chance to restart
3. If TWRP asks for a password, skip and wipe all the partitions, if it doesn't, wipe them anyway to install the new ROM.
4. Backup efs and persist to my SD Card (will they even be there after I wipe the partitions?)
5. Right after that install the custom ROM
6. Reboot, not get into a bootloop and still have my IMEI. Profit.
Is everything right or did I misunderstand something?
Thanks!

Answer for your questions
1) losing of IMEI no is possible on custom ROM too, but taking the backup of EFS and persist will retrieve them, so no problem. And losing of IMEI is random occur when moving from one rom to other.
2) just let the android boot once, so everything get loads up with unlock bootloader (no need to setup).
3)after installing the twrp, it won't ask for password since your device got format when unlocking bootloader, so it won't ask. If you want to remove encryption then format< type yes. It will remove your encryption.
4) for talking backup of EFS and persist use this method.
Code:
Use the following command to create a backup and save it at /sdcard/persist.img:
dd if=/dev/block/bootdevice/by-name/persist of=/sdcard/persist.img
To restore use the following command:
dd if=/sdcard/persist.img of=/dev/block/bootdevice/by-name/persist
If you have saved a backup using different name then use that name instead.
And seeing your plan, everything seem good, you can continue with your plan.
Note:- for some user PE won't work for them with 2gb version, so I suggest you to take a backup of stock ROM or keep an other rom file in case it needed.
