[Q] Lose data with flashing a new rom?

I have several apps and data on my Desire... Currently I am running a MIUI-rom. I already made a backup of the rom... If I decide to flash a new rom, does that mean I will lose all my data, like saves from games and stuff like that?

hi,
so if you dont backup them you will lose them probably
TitatniumBackup can save your user apps + data, so this will not be lost
but system data(wifi spots, contacts, bookmarks, ...) could also be backuped but with care!
if you change the android version most of the system apps change and also if you change rom type it will probably not work.
i can tell you how i do save all my data.
1. i do a complete nandroidbackup (if you want 2 go back from where you came)
2. a Titanium´Backup (sometimes system data could also be restored)
3. i use MyPhoneExplorer to backup my Contacts
4. MyBackup Root, to save my Sms/mms and other stuff (exept from Contact wich are put in the Google Account i like the app
Sounds a little bit much, but most of the apps have advantages at some point but also flaws on a other point!
ps.: yep i know most of them could be stored in the cloud but i like it lokal

I use the Google backup feature when registering my account on first boot.
Last time, all my user apps and data restored, plus wifi profiles, system settings etc (even my wallpaper) were reapplied. I did nandroid and TiBu also but didn't use them at all!
To use this you could nandroid backup, wipe everything, restore and check the options re backup when registering. Then wipe everything again, flash rom of choice, and wait. You may need a reboot for all the changes to take effect!

that kind of datas are stored in SDCard, so if you don't format it, you should not have problems, but always do a backup before flashing

I9000 & Titanium Backup

Just a very quick question, as I can't find an answer on forums.
When running a backup with Titanium which is the best approach?
1. Back-up all User Apps and System with Data
2. Back-up just User Apps with Data?
The reason im asking is if System Apps with Data is not selected, i presume that I will not have all text, emails and preferences that I have setup?
Can someone correct me if im wrong
Thanks,

1st option, backup all user apps. I found it's safe to backup & restore wifi access points also (although not between CM and stock ROM), other system data ain't safe. You have SMS backup & restore for SMS's, no idea for E-email (I use Gmail), preferences should be set again manually just to be safe.

Well, I suggest to use NanDroid Backup to backup everything to SDCard. Nandroid also backup android settings/ apps, so I suggest do this backup only if you're going use same Android version as you currently on.
Otherwise I sugg you to do only User's Apps/Data/settings backup.

Hi,
Please don't use a nandroid backup from a different device to a new one. That can cause many issues, including destroying your new phone if you restore system or EFS by accident.
Try titanium backup maybe for User apps only... no system apps. Or again, might be serious issues.
If you saved contacts to your Google account, they will be on your new device the minute you log into your Google account during setup of the new phone.
If any other apps don't restore data properly, that's just something you'll have to live with. ?

Which is the best app to allow full backup of our device?

Hello, as some of you know, after I used Keis to backup my device, did a factory reset and restored the device, I found that some of the data and files were not backed up. Since Keis cannot do a good job in backing up the device, why do we need Keis? Is there any good app that can do a full backup/clone so that after restoration, the device is like it is before a factory reset? From Helium Wiki, it says that the app does not backup photos nor videos. It also does not backup system files, widgets, device specific apps like s-note or s-memo, contacts, etc.

I usually keep personal things ( documents, photos, etc. ) on the removable SD card, and then use TWRP to do the backing up of the device. Quite frankly, having TWRP backups has saved my bacon many, many times Another option would be Titanium backup, which has been around forever and has a very large user base.

Thanks. By TWRP, do you mean TWRP Manager (ROOT)? I don't know if ROOT means it only works on rooted devices. As far as I heard, Android 4.4.2 on our device does not allow saving on SD card. How do you do that?

Yes TWRP is a replacement recovery which you boot into prior to the OS booting using particular button combination. By loading prior to the operating system it allows for the complete backup of all files (system and all).
Essentially for the best possible outcome with regards to backup and restore it is best to have root which gives you full access to system files for backup and more importantly for restoring which requires the ability to overwrite system files.
One of the reasons I insist on having root on my devices is that I keep a backup of all applications using Titanium Backup such that if I'm ever disatisfied with the way an application update performs (lets say a developer updates their app and the new version has bugs in it) I can always roll back to the prior version if necessary. It's very handy for this purpose.

How to keep/back up user data after disabling forced encryption

I have installed Nougat and done lots of customizations. I just learned that in order to root and disable forced encryption I have to wipe user data. Is there any workaround? I don't want to lose my data.

Removing encrypting and rooting are two different, independent things. You may decide to root only. Then wipe is not necessary.
(Do a backup in any case)

My experience with encryption is not that bad. I have an encrypted RETUS variant that's stuck in MM with a November security patch. I flashed xperience nougat ROM along with magisk (which comes with root) and everytime I reboot or boot into TWRP I have to put in my password to decrypt my data partition.
The only workaround to backing up and removing encryption that I know of is to make a backup with titanium, this is almost as good as a TWRP backup of data given you know what you're doing. After the backup, you can copy the titanium folder onto your PC before you wipe and then copy it back in to restore the backup.
