Well I wouldn't give up and consider it dead. Definitely a tough task for couple people, when Samsung employed thousands of men and women to basically engineer systems in place to prevent access to the kernel and bootloader. However, best believe if enough time and effort will be put, eventually you will crack it. Then people like myself and many other will consider you guys true geniouses in the android/samsung community and I have a feeling there will be many opportunities to hijack other devices as well. Regardless from my ongoing read of this thread, it looks like the solution for the Samsung Note 8 is through tampering with the hardware and most likely voiding the **** out of the warranty beyond what root access does. Since these devices are pretty pricey as it is, is unlocking bootloader worth it than using the initial SamFail root that was found last year?
The method that i think will work does not require taking the device apart.
If you are upgraded past rev3 bootloader then yea. Your pretty much out of luck.
I think there is some confusion because this thread dealt with multiple very technical issues.
At the end of it all...or basically were we are at here is this.......
I believe the best bet in running a custom ROM or Kernel is to inject U-Boot into the scene.
By that i mean to get Root initially using Samfail Method.
Modify the safestrap script (e2fsck) to load a Bare Metal Binary Version of U-Boot to accomplish having u-boot functionality.
Utilize the TFTP Boot function of U-Boot to load a Custom Kernel.
U-Boot could be utilized to load custom Rom as well or Simply use U-Boot to load a custom Kernel with Kexec Support and then use the standard safestrap slots and kexec to run whatever rom.
Honestly at this point I am not working much on the Note 8 anymore.
I recently bought a Hikey 970 Dev Board.
The power of the hikey 970 is far above and beyond the samsung devices.
Kirin 970 SoC
4 x Cortex A73 @ 2.36GHz, 4 x Cortex A53 @ 1.8GHz
64GB UFS storage
One of the things i like the most it it has A Mini PCIE Slot and also a M.2 M Key Pcie slot.
You can add any pcie cards and also run NVME SSD.
So i have been developing for the hikey now.
Once i have a solid understanding of the inner workings of U-Boot I may be more capable of pulling this off.
