Hello,
i want to flash an Custom Rom with Mobile Odin Pro, without tripping my Knox.
After the flash, how can i wipe data, system, dalvik cache and cache, with the stock recovery?
I dont want to do a factory reset, because my internel sd card is full and i have no time to copy it on my laptop.
Thx a lot!
Hi,
I've recently done a succesful flash of Blisspop after a full wipe.
Now I want to update, but I don't want to do a full wipe. Simply installing the zip on-top gives a permanent booting screen. Can you update without starting from scratch?
Did you wipe cache & dalvik after flashing updated zip?
I did not. Is that the only required extra step? And will I lose data if I do so?

No, you only lose data when you wipe the data partition
In recovery, you'll see different named partitions, cache, dalvik cache, system, data, etc etc
If you wipe System, you wipe the ROM
If you wipe Data, you wipe your user data
Caches are just temp partitions, safe to wipe any time, only side effect is a longer first boot as Android needs to re-cache everything
But yes, you do need to wipe the caches when updating to a newer version of the same ROM/Droid version, and no you won't lose your data
Here's how I do it:
Wipe System
Wipe Caches
Flash new ROM
Flash new Gapps
Flash SuperSU if needed
Wipe Caches again
Reboot
Result = New ROM with no loss of data
That's a clean flash, a dirty flash is how you did it without wiping System
If you are moving to a newer version of android, or a different ROM, wiping data becomes more necessary, especially if the move is to an older version of droid
Thanks. I'll try it out.
I wish to move from stock b574 to sokkoban's.
My biggest concern is that in the description given, it requires wiping data. Given that I am already on marshmallow, is there really a need to wipe data in twrp? Won't cache/system wipe just do? I don't want to wipe my internal sd plus file structure/dates. Plus all my apps!
Call me lazy but am yet to find a backup system that will return all my files & apps as they were pre-flash.
Any ideas?

actually, huawei has pre-installed backup app.. and it works great... you can backup every app plus app's data too... but backing up all those may take time..

in teory no you dont need to wipe data ...
as you know sokkoban rom must be installed via twrp
so you can :
fisrt
install twrp
make nandroid backup
install sokkoban rom without wipe
if does not work you can try to
wipe and install sokkoban rom
recovery from your previus backup the data partition
Thanks guys. I can confirm you do not need to wipe data to use the custom rom. A simple dalvik & cache wipe did it.
Hi
I want to root my phone and I will follow the steps in this video
https://www.youtube.com/watch?v=M8ji0yjf7IY
Will rooting my phone means that my data will be wiped ?
No. Not unless you do some sort of wipe in your custom recovery.
Is it currently possible to root the S8 without wiping data? Installing TWRP obviously requires a wipe but I dont remember having to wipe data while using CF Auto root on my S7. Can anyone confirm whether or not this is possible?
