First attempt at something myself (following Joying instructions - so they did all the work, really)
Instructions:
- two files required (6521_1.zip and 6521update)
- copy onto an empty MicroSD card
- put into your head unit and hope it works
NO WARRANTY. I AM A VILLAGE IDIOT. I TRIED TO FLASH THE JOYING ZIP AND IT BROKE MY RADIO UNTIL I REFLASHED THE ATOTO ZIP! I COULDN'T EVEN GET ADB WORKING.
<stop> I GUARANTEE NOTHING <stop!>
What I did:
1) Patched the boot.img using Magisck (using my phone)
2) Added to the S8 Ultra zip (download from dropbox if you get into trouble)
3) Used SignApkv2.jar (Java8) to sign the zip file (avoiding locked bootloader issues)
4) Copied the updated 6521_1.zip file into Atoto's firmware unzipped MicroSD and reflashed with patched boot.img
5) Installed the Magisck v7/22.01 onto my head unit
5) Installed kali linux and su into root
Copy to your own Cloud first (for link longevity):
Compatible Firmware Versions: S8 Ultra (whatever firmware came with it, there haven't been any firmware updates)
Unknown Compatibility: S8 Premium/Pro/Other (maybe?)
