Going from Stock Android 8 --> Android 6 + Transferring all app existing data - OnePlus 3T Questions & Answers

I'm currently on the stock Android 8 ROM. I'm planning to go back to the Android 6 ROM.
Does anyone know whether there is still a method to achieve this?
Is there a way for me to backup all apps + their data and restore everything in the new ROM? Not sure whether I need to be rooted before a backup/restore.
Can TWRP backup apps + data from Android 8 --> Restore them to Android 6?
By backup I'm not talking about contacts, messages only. I mean all the app data (meaning signed in session, or whatever data has been created in the present apps). I've been searching for this info but not finding any info. Please help!

What is the best way to Backup User Settings between ROM Upgrades

Currently I am using CM 5.0.6-N1, it's running really well and I've spend many hours installing multiple applications (SD Card) and configuring many of them and system parameters as well.
I would like to test CM 5.0.7-N1-Test 2, but before doing that I would like to know what type of Backup Process I should follow in order to keep:
- All my currently installed applications in the SD card
- Keep all my application's configuration
- Keep all my system's configuration
- All my downloads from the Market
- Etc.
I know that everything related to Google will be saved automatically.
Is there a way to upgrade the ROM and after a quick restore to be in the same configuration I am now but with an updated version of the OS ?, thanks a lot
Post in the right section please read the rules
I use the donated version of titanium backup.
It saves all applications and user data.
You do the upgrade and everything should still be there. If not. run titanium restore and voila!
Just make sure you don't select to restore any of the google apps since it'll overwrite the newer version.
I used the nandroid+ ext feature from amon_ra recovery 1.7.0 and it seem to backup my apps. When I went and tried the Desire rom. Didn't like it so i went back, restored with nandroid and all my apps were back on SD.

What's the difference in Recovery 1.7.0 between Nandroid and Nandroid+ Ext Backup ?
Do you know if the Backup Current ROM option in the ROM Manager application will have the same results ?, thanks

What's the difference between using Titanium's Backup, Recovery's Nandroid Backup and ROM Manager's Backup ?, all of the will back up the configuration and apps only ?, or some of the will backup the full Android OS as well ?, thanks

Nandroid is just a back up of your OS and settings.
Nandroid + Ext is a backup of your OS, settings, and A2SD which are stored in your EXT partition.
Dont know about Rom Manager, never used it.

But If I perform a Nandroid+ Ext backup of the existing ROM (CM 5.0.6) and then install a new ROM (CM 5.0.7-Test2), and then I do a Nandroid Restore I will replace the new ROM (CM 5.0.7 Test2) with the old one (CM 5.0.6) ???, please could you clarify
I only want to Backup my applications, settings and system configuration, not the ROM itself, thanks

ooo. So your trying to install a NEW rom and restore the settings to that one? You will probably want to use one of those apps from the market. I thought you wanted to try out a dif rom to see if you like it and then go back.

Exactly, I want to install a new ROM and then restore my settings and applications to the new ROM.
Here is the thing, every 2 to 3 weeks there is a new CM version, I like to be on the edge and always using the latest version, but I do not want to have to install all the applications and configure the setting every time.
Maybe Titanium Backup could be an option ?, thanks

If your just updating from CM roms you shouldn't have to WIPE. WIPE is what deletes those settings. If you are on a CM rom just install the newer ROM and it should be fine.

Even if I am installing a Test Version ?, like going from 5.0.6 to 5.0.7-N1-Test2 ?, thanks
You can use Titanium Backup or MyBackupPro. Both work very well with backing up your settings, apps and market links. I prefer the donate version of MyBackupPro because it always seems to get the job done without errors. I have issues with Titanium Backup quite often(Lots of FC's with certain apps after a restore). However, I do have both installed. It would just be whatever your preference is. Try MyBackupPro for simplicity sake and go from there. You won't lose anything if you use either one when switching ROMS.

You will prob have to wipe. Either use on of those backup apps or just redo it. Create nandroid backups for each. so you dont have to worry bout it next time.
Titanium Backup has been my lifesaver. I switch back and forth between the CM5 and Desire ROMs on what seems like a near daily basis.
Since you're using primarily the CM5 ROM, here's my suggested procedure using TB
1. Run the Backup all user apps + system data script
This backs EVERYTHING up (account settings, home screen layout settings, launcher settings, all your apps including paid/protected, the works).
2. Do your ROM upgrade.
2a. If you do a clean/wiped upgrade, just skip all the initial setup steps on first boot. TB will take care of restoring it.
2b. Re-install TB from Market as necessary.
3. Start TB and Run the Restore missing apps + system data script
4. Reboot (not necessary, but highly recommended)
VoilĂ . All your apps (including all their settings) are restored.
NOTE: I don't know why, but I always seem to have to manually restore the launcher/home config from TB. If your home icons don't restore just manually find 'launcher' in the list of backups in TB and opt to restore it.
Another cool (but unadvertised) thing about TB is that it integrates the labels/categories from a program called Apps Organizer. So, you categorize all your apps into whatever categories you want in AO and when you go into TB there they are, ready for you to filter you backups by category!

[Q] Updating, Wiping, Restoring and Titanium...

Dear community,
today as a first step I have successfully rooted my Phone (Froyo 2.2.1) with CF-Root Kernel and Odin, yay! Thanks to all the Developers, Guides and Refs on this page!!
In order to fix my ongoing battery issues,next thing I want to try is to flash a new ROM; I think for stability and for practice the latest Froyo Build JS8! I have downloaded Titanium Backup and have successfully backed up all my system and user apps and settings.
Now when I flash the new ROM, the phone will be wiped, or at least the Wipe-method is recommended (hard-reset AFTER the flashing?).
Can I restore at least some settings and apps with my Titanium Backup Files (I read restoring system apps/settings is not recommended)?
How would I do that (where does Titanium save the backup files?)
How do you guys usually perform the steps to a new ROM without losing all system settings, apps, app-settings etc...?
Thanks for all recommendations!
I would recomend you, restore user apps only. It will restore your apps and their settings. You could do it in batch mode.
Also is recomended to copy your TitaniumBackup folder to PC
Last but not least, do not forget copy your EFS folder too.

1) Get titanium backup PRO.
2) Batch backup your whole system (while you're at it, create a schedule so your phone automatically gets backed up at least once/week). The files will go on your sd card in a TitaniumBackup folder (actually you can specify where they go).
3) Go and nuke your phone with whatever.
4) Re-install Titanium backup, then batch restore your USER apps & settings. Leave the system settings alone for now.
5) Okay for system settings, be a bit more selective:
6) Go to Backup/Restore tab, select menu, then filters, then apply a Filter by Type: System.
7) Anything in GREEN is system settings (red=system applications).
8) I typically restore the following: Contacts/Call-logs; SMS/MMS/APN; Bookmarks; SMS/MMS Preferences; Wifi Access Points; Calendar Storage (think that includes your alarm clock settings).
Note that you may need to reboot before you see the restore take effect - e.g. you can't see your restored sms till after reboot.
Also it's safest to grab a copy of your titanium backup folder and put it on your computer. Lookup how to get a copy of your /efs too.
Thanks for the swift answers and useful guides! Will buy the Titanium Pro for sure.
In the Pro Version it says it can convert System Apps into User Apps and vice versa. Couldn't I just convert all the System Apps into User Apps and then restore everything, once on new ROM?
About the freezing feature of the Pro Version: Does it freeze complete Apps, or can you tell them to freeze specific tasks? I noticed that for example some Google Maps or Latitude tasks run in the background (and start again by themselves if i close them manually) and I would like them to get out of the phone memory while I don't have the program running. Yet I want the apps to function properly once I need them.
P.S.: Before I proceed flashing a new ROM I will also look into backing up my /efs folder so thanks for pointing me at this!
Okay, I figured out how to backup the /efs folder via ADB shell.
Questions remain though concerning Titanium Backup Pro. Can someone that uss Titanium Pro help me with these questions?

You could convert it technically. But generally it's not advised as it may mess up settings or so on a different ROM. I backed up my system stuff but I doubt I'll restore it on any ROM, the hassle isn't worth it if any issue shows up and you have to check everything out to fix it. Maybe some individual system thingies can be restored safely but keep in mind lots of system stuff changes on each ROM and could be incompatible.
Just like others did here, I also recommend the PRO version as you have to click every single restoration on a batch restoration otherwise (and it's probably slower anyway).
Freezing means just that, it freezes the app. It "deactivates it", so it's not there/usable but it's not uninstalled. Can't think of a scenario right now where this would be useful except for testing purposes, maybe if an app causes an issue and you want it to be gone temporarily or so.
If you don't want an app to continue running simply use the task manager to kill it which comes along with the SGS (Samsung app afaik, usually pre installed).
Btw Titanium has a nice wiki website which is really helpful but can't link it as a new user here. Google Titanium Backup wiki and the first link should be the correct one.
Correct me if I'm wrong but if you do a app+data restore the app doesnt show up in the market under installed which means that any updates to the app wont get rolled out.
What I did was install each of my apps from the market then did only a data restore. This worked for most of my apps BUT last night I noticed a few of my apps missing, in fact launching my angry birds from simi folder caused a FC. BUT I know that angry birds was working earlier in the day.
So I simply went back to the market and reinstalled and all seems well again.
So now I'm wondering what is the best method to restore, my method or maybe do a app+data restore then go to the market and install the app again.
Afaik, normally Titanium also backs up the links for the markets so the entries won't get lost and should be restored as well. There was an issue mentioned which can happen if that data gets corrupted. The Titanium wiki lists it.
Generally, installing the app from the market and then restoring it should work just fine.

[Q] Nandroid backup and flashing rom with wipe

Hi,
general question about upgrading a new firmware.
When I do that and I got a "wipe" firmware, I usually wipe and reinstall everything and reconfigure all my apps.
It takes a while but, as seasoned windows user, I know this is the best way to have a clean and full speed installation so to avoid "registry" cluttering.
Is this applicable also to Android? Or using Nandroid or Titanium I can restore my apps with "messing up" with my shiny new firmware?
It is quite quick to put your credentials on facebook or foursquare but all the word learnt by swype or all rebuild all the folders structure is taking a while...
Thanks
Sergio
Using Titanium Backup, you can just backup user apps and data, and leave system apps alone. Then when you upgrade to a new firmware (I recently went from KK5 to KL8) you can use your Titanium Backup just to restore the user apps and data you backed up, and leave the system apps and data alone. That way you'll have only the system app data from your new ROM, but all the user apps and data from your old one.
When I flashed my new ROM, I went ahead and selected to restore all user and system apps and data. Of course I can't tell you how my phone's performance compares to if I hadn't done so, but I can tell you that my phone is faster (because of the new code, I'm sure) than it was before, and I'm having absolutely no issues whatsoever.
I do my ROM backup using ROM Manager by CWM, app + data backup using TBP and EFS folder using kTool. It always works well.
In one of the stock LA1 firmware threads in the dev section (stock LA1 is a wipe firmware) a user has reported success by restoring his data partition from a previous Nandroid backup.
Haven't tried it myself, as I agree with your approach of starting from a "clean" slate. Android doesn't have a registry, but the DBDATA partition could be considered similar?
I prefer the clean slate approach, but after I instructed my Custom Dictionary for one month and organized all my apps in nice folders I wanted to understand if there are risks here.
It is not clear for me what are also the information related to a certain fw that an apps saves... is that possibile for instance to do a restore in ICS of a backup done in Gingerbread?

[Q] titamium backup firekat update....Please help

Ok. So I'm new to a lot of this....I'm installing a new update of firekat V7 from V6. My question is I have I wipe and install correct and if so. Can I backup all my user apps and data using titanium and restore it all back again or do I have to start fresh pretty much? Would it cause any conflicts?
Yes. That is what it is for. You can even backup system data.
If you ever have a major update, or change ROMs completely do not ever restore system data. Just apps and app data.
So just in your case, just backup you apps and app data and then do the normal steps to install your update. After you are booted you can install it from the play store and then restore your apps.
I suggest getting the pro key as well. It will allow you to batch restore all the apps.

[Q] Help me understand the "rules" for restoring data with a new ROM?

Since most ROM updates require fully wiping memory, restoring data is an essential step. Simply restoring the SD-Card, photos, music, etc, is not sufficient. There are many other types of data, such as call history, SMS/MMS messages, Wi-Fi networks and passwords, bluetooth pairings, etc. that need to be restored also to return the phone to its working state again.
Several ROM developers have cautioned to not use Titanium Backup to restore system data with their ROM. As alternates, I have seen suggestions to use MyBackupPro, Samsung account, or others.
Could someone explain (or reference a thread that explains) the differences between these types of backup/restore? What are the underlying issues that have to be kept in mind? How do these different backup programs save and restore the data? Which are suitable for ROMs that change the system structure? What is the full set of backup restore options that are compatible or incompatible with various ROM updates?
Could the Titanium Backup XML data format be compatible with all ROMs even if the binary format isn't?
Personally, I restore my apps using TiBackup all the time. And I use superbackup to restore sms, call logs, contacts.
Never really had a problem.
Maybe when restoring across a new build there could b issues.
But other than that, restore whatever the he** you want. Lol
Cheers
Here is one reply I received regarding restoring from Titanium.
For the Rapture ROM, iB4STiD says:
Q. CAN I RESTORE SYSTEM DATA WITH TITANIUM BACKUP ?
A. NO!! THIS INCLUDES CALL LOGS, SMS, AS WELL AS APPS AND THERE DATA!! OTHER WISE YOU WILL HAVE APPS FC, AND OTHER ODDITIES!
Here is a response from an earlier question from a different developer.
I'm not familiar with SuperBackupPro - does it do anything different than MyBackupPro? I'm trying to figure out what aspect of the different backup/restore programs is or is not compatible with system data.
You should never use Titanium Backup to restore system apps or data since they are built for a different rom and will most probably cause problems. I always use TiBu to restore user apps and data. I use SMS Backup and Restore for text messages. I don't care about call logs but I would think that there are apps that can back these up. I re-setup bluetooth and wifi from scratch since that only takes seconds. Note that some roms I have tried over the years have cautioned not to use TiBu to restore anything, but have worked anyway for user apps and data. Some roms do really not allow you to restore anything (odex instead of deodex perhaps - I am not sure) since TiBu just hangs when it is trying to restore. When this occurs, I just flash a different rom since I would not take the time it requires to set them up from scratch.
I have never had a full wipe delete any pictures or other media but then I never wipe the internal or external cards, just system, data, and caches.
I always use tibu for user apps and data and the xml format in tibu for sms and call logs. Have done this for as long as I can remember over at least 5 phones. I even move backups from phone to phone and rom to rom. (went nexus 5 to note 4 to another note 4 and from cm13 back to kk).

Thanks for clarifying. I thought TiBu's XML format would be safe, but I'm glad to have confirmation. That covers the main requirement for restoring.

I use the standard backup and restore for apps. I just use the xml for sms and call log.
