Reflash Stock Rom without losing ANY Data - Samsung Galaxy J7 Questions & Answers

Hey guys!
Story time!
So after my warranty ended (1 year) i rooted my J700F. And after 1 year of root.......i chose to go back to stock (i mean to remove any modifications i did like installing a custom recovery) But i dont want to lose my emails on my stock email app......and i really want to get software update back.
Any solutions and suggestion will be highly appreciated!

Normally Odin won't erase your data flashing a stock rom. But you could use SmartSwitch to backup your data first.

1. IMHO, you should extract necessary settings or data and restore to your new rom. You can use AppExtractor
2. No need to delete everything before restoring
3. Your choice. There is touch version out there. Try and love it

Thanks for your reply i really appreciate it.
i was saying that if i wana go back to my stock rom (original rom) wich is not rooted can i restore it using CW?
if i flash back to my stock nandroid backup using CW my phone will not be rooted and it will restore the default samsung rom?
its just my theory though i haven't tried it yet i`m asking question like this for my future reference
Well...
Yes your device wont be rooted and will return to the stock rom.
Since the nandroid backup copies the whole partition. just like Norton Ghost does on the pc, so your phone will just go back to its exact status it was at that time.
You wont need to wipe user data/factory reset, because of the data partition being restored by CW.
Well you are asking for a recovery. How did you make a nan backup if you have no recovery?
Or you used the stock one? if you used the stock one, aren't you able to use it to restore?
Or do you want a new more powerful recovery?
As in the previous post they mentioned, use the one you like, with the most options

[Q] Will flashing through Odin wipe all of my data?

I've accidentally thrown my Note 3 into a bootloop and need to reflash the stock firmware. Will doing this wipe all of my data? If so, is there any method of preventing that? I really don't want to lose any data. I think I'm already running the stock firmware, unless Kingo replaces it automatically, so I'm flashing the same firmware, I think.
If you flash stock firmware thru Odin.... of course you will lose all of your data

[Q] Upgrading While Rooted

So, I know that OTA will fail since I am rooted. I am on a Sprint S6 with OC9. I rooted using the T-Mobile Auto-Root.
I see that OCF was published for Odin to flash back to stock. My question revolves around the recommended procedure for flashing with stock. I use Titanium Backup. If I backup, then flash OCF, will this also erase all data on the phone to the point where I have to restore all backups and customize the phone all over again? There's just some things Titanium can't restore well. Or is there a way to update the ROM without wiping everything (dirty flash)?
Given the phone has built-in storage and no microSD, does the storage partition ever get wiped unless I do it manually?
Also, is there any sort of change log for the stock ROM versions? Or do they seem to be just modem updates at this point?
I don't know much about this phone yet since I just got it but coming from a nexus 5 flashing a ROM would keep your data but in this case since it is a system image you will probably lose everything in your storage

Any way to update XtreStoLite without wiping? (getting bootloop if I don't)

Hi
I tried to dirty flash XtreStoLite 2.2 from 2.0, but I got a bootloop, so restored to 2.0.
But I got so many things on my phone that it takes an hour or two to set up, so is there any way to update without doing a factory reset every time an upgrade is available?
Thanks in advance
Via recovery try to backup rom. And later in the new rom try to restore only data
Flash this via odin.

Mind if I ask why?

Reverting back to stock recovery

Hi,
I flashed Twrp but I can't backup, because it can't mount data.
I thought, I'd try to revert back to stock recovery and then flash twrp again.
Does anybody know how to do that without flashing an entire stock Rom?
Thanks

Hi
Why you just flash TWRP again and start from begining?
Anyhow if you wish to reflash your stock recovery You need to reflash a stock boot.img
Here you have 2 ways to do it:

In those threads the point was to re root but the principle is valid you can use them as guides

I had this problem and found out in my case, at least, it was because when I rooted, I didn't "format data" during the process. I've been told that if you don't format data during the process, you leave the data partition encrypted, and thus it can't be mounted (at least by non-system apps and processes). No guarantees here as always, but If you back everything up and redo the root process and do the data format, then you may be able to mount data. At that point you can restore your apps and info. I've also read (but haven't tried this!) that you can do a nandroid backup and restore ALL your data from that nandroid after you reset your phone (which the data format will do). You should google everything I have suggested and see if you can get what you need in this way, without having to reflash the ROM entirely or try to revert to stock recovery.

Hi. Yes, I had to format everything. Now it works. Also the issues I had with Titanium Backup are gone. I flashed the ExtSdFix and I'm almost running like on Kitkat, yeah
