I cannot extract the token because my device was not rooted.
I bought a new microSD and clone in it the microSD from my device.
When i put this new card the phone recognize as the old one.
I recover photos, media from whatsapp, apps ...
You can always format from command-line to be sure where the problem is (if any). This will erase your whole /data partition which contains personal data, apps etc.
Boot to TWRP recovery.
Find block device for userdata partition. Usually it's symlinked at /dev/block/by-name/userdata or /dev/block/bootdevice/by-name/userdata. See FINDING BLOCK DEVICE section ...
Actually Android 6.0 had Full Disk Encryption as specified in the Android 6.0 Compatibility Definition Document - Section 9.9 Full Disk Encryption with exceptions if the hardware was insufficient to perform the operation.
So your case of a not specified lockscreen password is actually called out:
If the user has not specified a lockscreen passcode or ...
I was in a similar issue on a Nokia running a stock ROM. Basically Magisk module killed my phone and the TWRP won't allow decryption.
I was able to boot successfully to system again by.. Removing Magisk, because in the absence of Magisk, the Magisk modules shouldn't load and hence the system should boot just fine. I did that by flashing my stock boot image....
Your phone launched with Android 10.
In Android 10 Full Disk Encryption has been dropped in favor of File Based Encryption
You no longer need to "encrypt a disk" as everything is encrypted provided you have a lock screen with pin/fingerprint/etc. in Android 10
All devices that run Android 5 and beyond (out of the box) are encrypted. That's probably why you don't see a separate status for device encryption as you see for Ext.SD.
Encryption can be Full-Disk Encryption (FDE) or File-Based Encryption (FBE). The device is encrypted on first boot using default encryption and once the user sets up lock screen mechanism ,...
is there any reason as to why it doesn't support end to end encryption, or is it a feature that they intend to implement at a later time?
RCS improves the old SMS by bringing modern features. It provides client to server side encryption but not provide end to end encryption.
According to What is RCS messaging? Everything you need to know about the SMS ...
Searching a lot over the web I saw this question and by reading the entire post, and in particularly this answer https://android.stackexchange.com/a/176124/77853 I brought back my phone to life and without losing anything !
What I had to do was (as suggested in the answer) repair the /data partition plus the /system partition !
Good news: trying the following command successfully decrypted my SD card without any errors:
sudo dmsetup create crypt1 --table "0 `sudo blockdev --getsize /dev/mmcblk0p2` crypt aes-cbc-essiv:sha256 [16-BYTE HEX KEY] 0 /dev/mmcblk0p2 0"
A couple of minor issues:
sudo mount -t /dev/mmcblk0p2/crypt1 /media/mint/sd returned the error mount: /media/...
The hex value you found in the wpa_supplicant.conf is the PMK (not the PSK directly but some intermediate value computing the PSK or something like this). This value is not encrypted, it is hashed as defined by WPA2 using PBKDF2 SHA-1 with 4096 iterations see Wikipedia.
SHA-1 is a one-way function, which means that it can not be reversed.
Wifi still works,...
I had the same problem, and what worked for me, I formatted it from command line, so while in fastboot mode I typed:
fastboot format userdata
Then I flashed TWRP and rebooted into it and the files in the storage were all showing, all was working.
Android does not encrypt system partition as there is no confidential data on the /system. There are only standard ROM files which are already available in public domain.
The encryption should only apply to the userdata partition /data or SD Card (if mounted as internal storage). Moreover /system is mounted as read-only. So, nothing can be tampered there.
The older Android versions were using Full Disk Encryption (FDE) mode, therefore the password enter dialog was a small mini-OS booted before the actual Android-OS.
This mini-OS was playing what you are a calling the "metronome sound" when it was waiting for the user password.
I assume this sound was introduced to ensure the user recognizes that the boot ...
The issue here is that RCS is not a Google product/service. Google serves RCS via a service called Chat, and Google Messages (the pre-installed, default SMS app on most Android phones) supports RCS. The Verge are pretty bad at conflating the two but even they say (emphasis added):
Google has been quietly corralling every major cellphone carrier on the ...
First. You need to understand, two gatekeeper enroll processes are involved in synthetic passowrd.
Here is the process:
generate synthetic password, it's just a random number
use real password to enroll a fake id. and get sid(secure_id)
use keystore to generate an AES key, and bound it to sid. and use it to encrypt synthetic password
use synthetic ...
I don't think is documented anywhere the syntax but looking at this code
I was able to set a different password.
Initially I used a PIN for unlocking, so the command to run on a terminal on lineageos 17.1 as root is:
vdc cryptfs changepw TYPEOFNEWPASSWORD OLDPASSWORD NEWPASSWORD
So I had the same problem with an employee to whom I had given a phone. She kept forgetting to charge the phone, so when it rebooted after charging she had to hand me the phone so I could type in the password and then switch to her secondary account. Tired of this, I read some articles about multiple users. I couldn't find the right answers (or didn't ...
