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?)

got everything setup I believe, downloaded the firmware and unzipped, patched boot image with magisk, re-archived it as zip with normal compression, signed said zip file with test key from zee russians lol... now in theory I would just place this on a microSD card and slap it into the slot and the system should recognize it? then install magisk after it updates? does the file system matter? ntfs? fat32? fatex?

This looks like you got the files for the s8 Premium from ATOTO. Would you mind sharing them?

Atoto S8 Ultra Plus (gen 2) Firmware Update from ATOTO Link:
https://www.dropbox.com/s/901k1f3o95kamb6/Update-File-for-ATOTO-S8-GEN2.zip?dl=0

Please kindly download the attached update file to your computer, unzip the update file, open the file folder, then directly copy all the files in it to an SD card( format of FAT32 or NTFS),
connect the SD card to the radio, and there will be an update notice popping up, click the "start" to start the update. Then the car radio will do the update automatically.
The total update will take around 10 minutes.
When the update is completed, you will get a notice on the bottom of the screen, and you can just disconnect the SD card, and the radio will restart.

trying to get the s8 premium files from atoto now hehe
This is what they sent me for S8 gen2 firmware update: https://www.dropbox.com/s/901k1f3o95kamb6/Update-File-for-ATOTO-S8-GEN2.zip?dl=0

And this is what they told me, " download the update file to the computer, unzip the update file, open the file folder, then directly copy all the files in it to an SD card( format of FAT32 or NTFS), then insert the SD card to the radio, and there will be an update notice popping up, click the "start" to start the update. Then the car radio will do the update automatically. " This reply maybe too late, and I also can guarantee nothing, still hope it can do a little help.

This Gen 2 file flashed without issue on the S8 Gen2 Premium S8G2114PM.
Has someone uploaded the firmware with the patched boot.img for root? Did i miss that detail in the thread?
Thanks

That gen 2 firmware flashed on my S8 gen Standard just fine. Have not gotten a chance to see if it's any different than what it already had on it though.

Before I updated the system, my Carplay connected slow, even with a cable. So I contacted ATOTO suuport team and they sent me the update file. After that the Carplay works faster than before, maybe that's one of the difference?

    Just wanted to say thanks, I successfully rooted my s8 gen2 standard today using these instructions and the posted firmware file. All just so I can use Tasker to turn the volume down two clicks when switching to the radio since it's noticeably louder than spotify.

    Just rooted my S8 Gen2 Ultra with the 2022-04-15 firmware. Patched and ready to go files can be found here:

    Instructions said to copy the files in the extracted directory to a sdcard formatted NTFS or FAT32. Neither of these worked. An sdcard formatted to exFAT worked perfectly. Note: Flashing the firmware erases data so you will loose all your settings. At least it did not erase the apps that I had installed.

    Now hopefully I can fix the micrphone button to open Google Assistant instead of Google Voice Search, along with fixing the AC-44F5 Front Camera button to open the HDDVR app instead of the FCAM app.

    Thanks @ChrisDos .
    So nothing needs to be done to those files at all? Just download and put on a card?

    Is the mic button the main reason for rooting or is there anything else you gained?
    Correct. Copy to an sdcard and go to town. I put the latest Magisk apk and just the patched boot. img in the zip file as well.

    Well, the primary reason was to fix the buttons. I also wanted to be able to backup my apps , use ADB wireless, etc. All my phones and tablets are rooted and have been since the original G1 phone.

    Please tell me what one earth I'm doing wrong, it's formatted to exFAT, it has the patched boot.img from the original file, renamed it, deleted and replaced boot.img from the 6315_1 file and inserted it into every USB port, they all ready and access it but no pop-up to update. These are pics of the files on the flash drive

    You have to take everything in that ATOTO directory and put it in the root of the card. So you have everything in a sub directory.
