My OP6 has the TWRP 3.2.2 installed, with OOS 5.1.9 and Magisk. I would like to try out the new HAVOC rom, so i have done a full TWRP backup of all the partitions of the phone, and another one with only the BOOT, SYSTEM and DATA partitions.
But I have many doubts about the reliability of the TWRP restore: I read several posts related to bootloop and failures. I would like to avoid having to reinstall the whole phone from scratch.
Has anyone successfully full backed up and restored on the OP6 with TWRP? If so, which partitions did you backup?
The alternative would be to use Titanium backup, but the restore procedure would be much more complex.
I want answers about this as well. What partitions do we backup? What's the process to restore? I tried backing up everything then restoring it and i got a blank screen when I was suppose to see the boot animation.

Our TWRP is very buggy i tried to restore whole backup using twrp and it failed showing error. But somewhere i got solution in xda.
Backup only data, system and boot and restore it will work.
But for safety always keep one extra full backup of all things like efs,modem, data, system, boot, vendor. Because sometime if something goes wrong u have rescue operation always there
Since this device is super easy to unbrick if needed I personally only keep a data backup of each ROM I use on my flash drive.
So I don't need to do a full setup when flashing a different rom.
Otherwise if something crazy happens and the device gets bricked, it's fixable with a PC.

Hello forums,
I have a rooted One running the latest official update version 44S with TWRP recovery. I am interested in flashing an Android Lollipop port (the one made from CM12 dailies). If I don't want to lose all my app data permanently (I know several resets and erases are necessary to swap ROMs), how can I back it up and then restore it once I've upgraded? Can I keep a backup of my current ROM/apps through the various resets necessary (just in case of big issues or bootloops)? FYI all my backups include system and data, but not cache.
Thanks to any help in advance!
If you're only backing up system and data, your phone will never boot when you restore the backup, you need to backup boot as well. You should always keep at least one backup on your phone at all times, just in case things go wrong. Unless you wipe your internal storage (which you don't need to do) you won't lose your backup. In regards to your user apps, just use Titanium Backup to back them up and then you can restore them after flashing a ROM.

Due to problems with Google Services on my rooted Galaxy S5 (SM-G900F) I opted for a reset from TWRP and it returned to a condition where after some initial screens it was just stuck at "Checking for Updates" so I went back into TWRP and told it to wipe the other partitions. Whoops - now I have no OS (I was sort of assuming that the factory reset OS was somewhere else)
Which is the stock ROM for my Region - UK, unbranded - where do I get it from and how do I load it using Odin and/or TWRP?
TIA
Hello,
Did you make a nandroid backup of your stock ROM or a nandroid backup of a custom ROM if you installed one? If you have a nandroid backup of either of those then you can restore them in TWRP by choosing the restore option and then your nandroid then swipe the slider at the bottom of the screen. If you installed a custom ROM at any time before this and you still have the ROM file then you can reflash the ROM and Gapps.
If you don't have a custom ROM stored anywhere but can still get to recovery, then you can download any of the custom ROMs compatible with your device and a Gapps package that matches it and put them on your extsdcard then boot to recovery and flash the ROM and gapps, do the normal wipes in recovery after flashing, the normal wipes(wipe data/factory reset, wipe cache and wipe dalvik cache), DO NOT CHOOSE THE ADVANCED OPTIONS THAT LET YOU WIPE PARTITIONS.
Check this thread to see if it is your stock firmware, it SHOULD be but double check first, it also has instructions for rooting again and installing recovery.
http://forum.xda-developers.com/galaxy-s5/development/stock-rom-root-recovery-sm-g900f-t2967725
If that doesn't work then go to Sammobile.com and search for your stock firmware by using your device model number.
The firmwares can sometimes be found at samsung-updates.com also.
Find the right firmware for your exact model number and flash through Odin.
For further assistance, post your question in the forum linked below.

Good luck.

Sadly not - wasn't expecting to need it, thought it would revert to factory default - I have Titanium backup of apps and data.
I am hopefully a few minutes away from downloading the stock ROM and hopefully can reflash that using ODIN.

Making nandroid backups in recovery is the most important and valuable function of custom recovery, flashing ROMs is its' secondary purpose Android is not like PC with a recovery partition that restores a factory IMG, on PC that factory IMG is stored in a recovery partition. The factory reset feature in stock android does not restore an IMG, it deletes all data from the user partition and leaves everything in system partition the way it is, if you delete a system app and then do a factory reset then you will still not have the system app that you deleted. Anything you modify in system remains the way you modified it if you use the factory reset option. You should only use the factory reset in recovery, not the factory reset in system settings when you have a rooted device with custom recovery.
I'm sure that when you found the recovery, the directions had to have mentioned making a nandroid backup of your stock ROM before flashing anything, your present situation is why you do that, so that if anything goes wrong then you can easily restore to the one ROM that you know for sure works with no issues.

I installed the TWERP recovery as part of the rooting operation and I didn't pay any attention to the backup option - I thought that's what Titanium did.
I am learning and will make sure that I take a Nandroid backup once I have it back up and running. Life would be so much simpler if only Samsunng didn't stuff their 'phones with bloatware that can't be deleted in stock mode.

Titanium backup can only backup data that you installed or downloaded, it does not backup anything that comes on the phone itself, that is what custom recovery is for.
When following guides to mod your device, read and understand ALL instructions before you even make the first move to touch your device. Get used to being thorough about reading and understanding first or you'll end up in a mess, possibly even hard brick your device, all it takes is one wrong move. Not all mistakes are fixable with android devices.

Is there a guide on how to restore a backup made in TWRP? I did this the other day forcing me to reflash the entire phone because it failed. So was just wondering about the proper way to restore backups on this phone?

It is a real pain but it works.
1. Store TWRP backup off the phone.
2. In TWRP wipe everything, then flash the same room as your backup on both slots. If using OOS, using the fastboot roms will do this easily.
3. Go through the initial setup in the OS.
4. Install TWRP (and Magisk if you were using it in the backup)
5. Restore the backup.
I know it is a headache, but the way this phone handles encryption makes it this way.

But this just sounds weird. I was on OOS 9 with TWRP and magisk. I app was misbehaving so I restored a backup I made the day before. Shouldn't that have worked? It sounds like this process would end up in the same situation. :S What about restoring only certain things, like the boot.img. Would that work?

I don't know to be honest. I did a lot of experimenting trying to port a rom (had to flash lineageos on the phone more than a few times) and would backup system, boot, and data. Then I would flash my failed rom, it would fail, and that process I wrote out earlier worked.
It is also possible that any and all Magisk modules we're causing your problem and starting with the fresh slate that the fastboot rom gives you would be important.
Also when you flashed OOS 9, if you didn't flash it twice you didn't have it on both slots, and you just restored your backup to the slot that didn't have OOS 9. The flash-all.bat in the fastboot rom will flash it to both slots.
Trying to get a clean backup before I go mucking about trying different ROMs, and I can't get it to work like I am used to. Just came from Nexus 5 for my wife and Onplus One for myself, backup was very simple. I am sure it's because I don't quite understand how A/B partition affects the backup, but I am not succeeding on solving this myself.
I am full stock updated to 9.0.3, unlocked no problem got BluSpark 9.93 TWRP and Magisk 18. If I make a backup, using default partitions or all partitions doest matter, when I restore it gets stuck on boot animation, and no matter what I do from there it ends up hard bricked. I have gotten quite fast at MSM Tool fix, and no major data loss because I have manual backup on computer, however I dont want to MSMTool every time I try a new ROM.
The ONLY restore I have succeeded at is to do a complete MSMTool fix, update back to 9.0.3, get TWRP and Magisk back in place, then restore JUST the data partition. that brings back my settings, apps, logins etc, but it is a huge hassle to do. I want to get to the point where I can say "meh I dont like LineageOS, lets just restore my clean Stock backup" and be done in five minutes.

hi same problem and a quick fix is to back up system image instead of system and vendor image instead of vendor
ps if you have a problem with password after flush this

Just backup data partition and flash your OOS zip when you want to return to OOS in TWRP. After you flash it, restore data and you'll be golden.

I tried that before but it either got me stuck in a boot animation or completely corrupted the phone with random gibberish named folders and having to MSMtool to recover. If I was on Havoc ROM, my understanding is that you cannot just flash the stock OOS zip over the top to return to stock.
Even if it did work that still takes out TWRP and Magisk, which is what i'm trying to avoid. I know it works different than it used to on the old partition setup, but is it possible to just swap back and forth between different ROMs using recovery backups? I would like to give Havoc and Liquid a week of use each but I dont want to nuke and restart my whole thing every time I switch. its fun to try other things but at the end of the day I still want to have a phone that doesnt need to be set up yet another time.

I only backup data, but I'm also decrypt, which helps. There really isn't a simple flip flop like you used to do. I backup data, then install OOS zip, flash TWRP, reboot recovery, flash noverity (for decrypt), magisk then kernel and reboot and all is the same as it was before.

thats a shame, it was really nice to be able to quickly change roms on my phone.
Regarding decrypt, I noticed one of my backup attempts was hampered when I had pin/fingerprint enabled before backup and since then I just make sure to remove all locking before backup. is this noverity thing used to strip the password from a backup or?
EDIT: so just to make sure I am understanding, when I do a backup in TWRP I can only really make use of the Data partition backup. and if i want to flash a ROM i basically have to do it as if it was a fresh install, get TWRP/Magisk back in, THEN restore my partition, every time I change ROM?

The best way to flip between ROMs is to take a data backup specifically for each ROM, but install the ROM as per instructions every time.
The noverity just maintains decrypt after you decrypt your data partition.
Restore your data any time while in recovery, and it'll be fine as long as it's data for that specific ROM. The order in which you do everything does not matter when restoring data and flashing the ROM.
EDIT: the order doesn't matter in regards to your data restore. Everything else matters in those steps, in their specific order, but you can restore data at any time as long as the other steps are in order.

Alright that makes sense, thanks for the help. again, shame it's not as easy as it used to be, maybe this will finally get me to settle on a single ROM and just be happy with the phone I paid so much for lol.

The a/b partition is a failsafe that also makes updates easier overall. OOS is a solid ROM. I would recommend xXxNoLimits. That's what I use along with Smurfkernel. It's all preference.
In the past I've always backed up my complete ROM incl. appdata with twrp. I didn't have to competely setup my device if flashing went wrong and reverted to stock. I had some bad luck flashing roms because the A/B slots are new to me. I now have my bootloader unlocked and everything setup on stock OOS, and made a twrp backup of super, recovery and data.
Before flashing another ROM I just want to make sure I can revert easily to the previous OS without doing a complete setup of app settings and stuff
My question is
Can I wipe/factory reset and then just restore with twrp?
Do I restore when in the active slot where current os is?
Are there any issues with password/encryption when restoring?
Expected scenario;
I'm on stock OOS, wiped and want to restore appdata, settings, homescreen, etc...
I failed to install custom ROM and want to revert to stock OOS without having to redo the entire setup
I did search google and this forum for an answer or guide but couldn't find one (please correct me if I missed a thread)

HI, yes I did
I am still confused because it says before a restore I have to disable screenlock, if my phone is softbricked or has no OS does that count as not having fingerprint/lockscreen enabled?

When you start TWRP, does it prompt you for a password/pin/pattern?
If Yes, then you have a lock screen password set. And if you can't get into the system to disable it, you'll have to format data (completely wipes all data).
If No, then you're good to go.

Hi, first of all; thank you for taking time to help me!
I managed to completely wipe the phone including data, and afterwards I restored it by copying the backup (which was now on my computer) and restoring it. SUCCESS! All appdata seems to be there, homescreen, and after second reboot my fingerprint still worked as before.
I just have one more question if you don't mind;
Below partitions I backed up;
Data
Boot
DTBO
Super
However, I'm not able to copy over the "super" partition from my computer to my phone, is this normal? it's almost 8GB and I was convinced I wasn't going to get to the OS without restoring it but apparently I didn't need it (?)
I suppose with the Fastboot Enhance Tool I'll be able to also restore this?
You really only need to backup the "system" partitions (boot, dtbo, super) if you're changing to custom ROMs. If you're always on OOS then you can forget about backing them up.
You should be able to copy the full backup, including super files from your PC to your phone using ADB. I've done that lots of times.
I've never used the tool you referred to. But I do know that you can't use fastboot to flash the super partition - it's too big.
However, if you break it up into chunks (I did it in 512MB chunks) using SparseConverter (https://forum.xda-developers.com/t/tool-sparseconverter-v1-0-1.2749797/) then you can successfully flash it.
Just to confirm, if a ROM bootloops and I don't have access to a computer, there's no way to restore the TWRP backup? Seems like this defeats the point of even making on-device backups (AFAIK encryption can't be disabled for many roms)

If you can enter TWRP (even if your rom bootloops) there is a great chance you can restore backup in TWRP.
