How to read Userdata.bin - Android Q&A, Help & Troubleshooting

hey there.
so here i am, after purchasing a box/dongle of sort , which allowed me to read and backup the partition that i had on the phone i received while not booting.
the phone is an MTK xiaomi redmi note 4 .
i did backup all the partitions before flashing it.
the phone was constant boot looping , was not solved by flashing it (not cn dev firmware or any other firmware) it did not even went to fastboot.
i have heard that after android 5? the userdata.bin were encrypted .
1, im not to sure if the rumors are true.
2, how its possible to decrypt it ?
3, if i flash the same partition to a working phone, would i be able to read the data out of it ? (note that the answer to that question was yes after asking some one, however it seems difficult to understand how, i mean if there is a key to decrypt the partition shouldnt be in the phone itself who encrypt it ?) hope u guys can clarify if its possible to so , or its just BS.
now if the keys are somewhere can i extract them some how and decrypt the partition so i can get the data out ?
i did try to open it with 7z , ftk imager ..
nothing could open this up.
this is how it looks like
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
alot of the partitions are fill with
Code:
G..Â.ªÕ.E)ÎJØÁõV
Code:
470305C290AAD5154529CE4AD8C1F556
i mean i can clearly see that its encoded and see the partern .
i did try to flash twrp, but that did not work (because fastboot does not comes up.)
anyhow , this is it.
thanks for the help in advanced .
(in short how can i save the data of this phone, cheers)

I think a convenient way to remove the encryption from your Android phone is
Go to Settings-->Security
Then under "Credential Storages" click on "Clear all credentials"

It was just a hint for everyone how to avoid the mistake you made. :laugh:
It is the whole point of disk encryption to prevent unauthorized booting. A once encrypted disk/img can't get decrypted by external means as you are trying to do now. May be FBI has the appropriate tools ... That's probably also the reason why Google will, as announced in spring 2019, in the end, remove adb backup/restore from Android.
IMHO you have no chance.
