Reset User Locks v 2.0

Partition UserData is Encrypted. Break..

Hello is that any possibility to recover user data?

layder · 07-24-2020, 10:36

you can't extract data from encryption partition directly from eMMC/UFS
partition is crypted with data from current CPU

if you need data - you need put CPU + Flash IC at another PCB (if you dead) and run device

such a procedure is almost impossible

on all modern android devices with android version above 6, encryption of user data is enabled by default.

The password on the device also participates in the cipher, and the decryption key itself is random and is stored in the processor of the device until the next wipe of the user partition, when it is accidentally created and saved in the processor again.

you can only theoretically access this encryption key and decrypt user data if you find vulnerabilities for hackers in a specific model of the device processor

key can be founded by BRUTEFORCE Method ???

if it's possible then implant that method on upcoming updates

FDE (Full Disk Encryption) key have length 256 bit (32 byte)
it's like private bitcoin key - have 2^256 variants

a3s a1k and other models have reset oppo button.is that phones don't have FDE (Full Disk Encryption)?

At now is 4-6-8 MB/s
At new core be x2 (for socket)

Thanks for your response. So even the phone have no password the userdata still encrypted? No posible way to read the data?
