hi all

couldn't find information about this using google or searching here.
Useful stuff i've found:
wiki. tizen .org/Porting_Guide/Tizen_Bootup_Overview (no information about signing or checksums) [remove whitespaces]
I was wondering:
1. Can I simply flash anything via Odin and it will still boot or is there some signing going on? maybe just some "custom" packing?
2. Has any1 built tizen "from scratch" using their repos (?
3. Are there more information about the bootloader(s)? do they use u-boot? (saw that in their git repo)

Thanks a lot in advance!

I suggest to choose wisely... because you can brick your device... and only bring back via USB cable for instance:

IMHO useless s h... depend what you want to achieve...

But you could use their daily Tizen 5.5 Images...
Maybe i will add later what I mean...

3. Are there more information about the bootloader(s)? do they use u-boot? (saw that in their git repo)
If you download Firmware for research... you would find sboot.bin Bootloader...

Meanwhile it seems I have progress with Rooting of Stock Firmware...
First test(s) on SM-R815U... with BSE3 Firmware...

In theory I could do this for SM-R800 too...

Best Regards

Wow, this is cool. Do you have access to Tizen 5.5 images? Is it usable as daily driver?

Sounds good! I'm interested into test the root for R800. Let me know if you need testers.

Thanks :good:

I am still waiting for feedback from SM-R810 user... :eek:

Here are the SM-R800 files... rooted...
https://forum.xda-developers.com/showpost.php?p=81329501&postcount=814


Here is how I create modified rootfs.img
Code:
sdb root on
sdb push .\GearS3root\R8xxSource_su\su /media/SDCardC/Others/
sdb push .\GearS3root\R8xxSource_su\fingerprint_list.xml /media/SDCardC/Others/
sdb push .\GearS3root\R8xxSource_su\fingerprint_list_ext.xml /media/SDCardC/Others/
sdb shell mount -t ext4 -o loop,rw /media/SDCardC/Others/rootfs.img /media/SDCardC/Others/2
sdb shell cp /media/SDCardC/Others/su /media/SDCardC/Others/2/usr/bin
sdb shell cp /media/SDCardC/Others/fingerprint_list.xml /media/SDCardC/Others/2/usr/share/ca-certificates/fingerprint
sdb shell cp /media/SDCardC/Others/fingerprint_list_ext.xml /media/SDCardC/Others/2/usr/share/ca-certificates/fingerprint
sdb shell cd /media/SDCardC/Others/2
sdb shell sync
pause
sdb shell cd /
sdb shell umount /media/SDCardC/Others/2

A
I have inject su Binary

B
I have replaced 2 files from Combination Firmware... to have full access to cert cr a p...
Platform, Partner signed possible...

C
Removed verityctl from end of rootfs.img... with WinHex

I am using Tizen Studio... to manipulate rootfs.img

Because I am Windows Fanboy. :D

Best Regards

WEAR OS

if it was done on the gear s, why isn't it possible to do with the galaxy watch or any others for that matter? I would rather have Wear OS instead of Tizen because of the universal capability to use on multiple platforms, plus the convenience of a plethora of apps. Samsung doesn't have versatility, or so it seems...
Is there anyone who has successfully rooted anything after the S2 and uses Wear?
