will i keep my data if i flash HOME_CSC update via odin?

[IngoPan]

Hi,

Will i keep my data on my rooted A520f if i flash HOME_CSC update manually via odin ?
Or will i have to format /data again after flash as the data partition will be reset?

Thanks in advance,
Ingo

Yes it should be okay. Check online first to make sure

"should be okay" - thats why i wanted to check online right here. Someone else knows for sure?
So i can flash binary structure AP+BL+CP+HOME_CSC?

As with any software thing, things can go wrong and thus why @moozer said "should be okay." If he said "yes it will work" and all your porn vids or whatever you have got deleted, there is a chance that a noob could get very mad at someone. After I am done this rant, yes theoretically that should work.

Thanks, so flashing this will not re-encrypt /data?

It shouldn't do.

From what i read here https://forum.xda-developers.com/android/general/how-to-backup-restore-android-device-t3602583 it will
erase internal memory: "Flashing Factory Firmware using flasher will also erase internal memory." ?

Your personal data will remain if you flash "HOME"

CSC – personal data will be erased
CSC_HOME - personal data should be safe

I've done it several times with no issues, however, that is not to say that it is 100% perfect 100% of the time for 100% of users.

BEST ADVICE... ALWAYS BACKUP

ALWAYS

Yes

 

[IngoPan]

all worked fine. thanks for heads up!

Yes HOME_CSC keeps all of the original data.

Well, I did it on one phone using home_csc - all data stayed intact, did on another phone - even though Odin reported flashing fine, phone crashed and I had to do factory reset - go figure! In both cases I used the same bin version of the firmware.

CSC!

AP : CODE
CP: MODEM
BL: BOOTLOADER
CSC: CSC or CSC_HOME
USERDATA: USERDATA same for when you need to wipe the user data.

Note: the firmware you are trying to flash should have the same version than your current version on the device or higher, otherwise you may get an error in Odin

I want to downgrade the latest security update is that possible? It causes some issues ?

Really not sure. Best advice has already been given - to backup if unsure.

If you choose to attempt a downgrade, ensure beforehand that a full TWRP backup is taken in case things don't go the way you planned.

Otherwise, check the forums for downgrading firmware discussions.

Unfortunately I don't have this device any longer, so cannot accurately advise you to say "yes".

Hope that helps. Let us know how you get on.
