08:45 <vakkov_> guys, any idea if I can obtain the bootloader of a TM2 device?

08:45 <forkbomb> it would probably be on the tizen website, if anywhere

11:03 <mszyprow> vakkov_: u-boot for TM2 is on tizen.org, but you also need a special 64bit enabled sboot (proprietary bootloader), because the stock Note4 mobiles comes with 32bit sboot

11:04 <vakkov_> mszyprow: any idea where i can get such an s-boot?

11:05 <mszyprow> vakkov_: no idea :(

11:06 <vakkov_> btw, i checked tizen.org and I never found such a u-boot

11:07 <vakkov_> mszyprow: when booting android they just jump from s-boot to the boot image, don't they?

11:07 <mszyprow> vakkov_: https://review.tizen.org/git/platform/kernel/u-boot

11:07 <mszyprow> vakkov_: but you need to log in first

11:08 <mszyprow> vakkov_: right

11:09 <mszyprow> vakkov_: the problem is that in case of Android Note4 mobiles this is done in 32bit arm mode and there is no back to arm64

11:09 <mszyprow> vakkov_: note that tm2 uboot does almost nothing besides reading compressed kernel and booting it

11:10 <vakkov_> yep, i'm aware of that... they have done it because of the Qcomm variant ...

11:14 <vakkov_> mszyprow: any idea about the exception level s-boot runs at? EL1?

11:14 <mszyprow> no idea

11:58 <vakkov_> mszyprow: wondering if they need to sign this u-boot in some way

15:21 <forkbomb> anyone familiar with u-boot? trying to port it to i9300. BL2/SPL works, but the iROM's "read data from SD" doesn't seem to work

17:17 <vakkov_> forkbomb: check the talks from Oran Avraham and his exploit here - https://github.com/oranav/i9300_emmc_toolbox; if i remember correctly u-boot was getting loaded from SD because the EMMC chips of certain galaxy s3's and note 2's were dying and iRom was looking for a bootloader on the sd card... but check his two talks (bluehat and the other one here - https://media.ccc.de/v/34c3-8784-emmc_hacking_or_how_i_fixed_long-dead_galaxy_s3_p

17:17 <vakkov_> hones)

17:17 <vakkov_> oops; https://media.ccc.de/v/34c3-8784-emmc_hacking_or_how_i_fixed_long-dead_galaxy_s3_phones

17:17 <vakkov_> forkbomb: iirc they were using this u-boot https://forum.xda-developers.com/galaxy-s3/general/totally-revolutionary-sdcard-bootloader-t2061437

17:22 <vakkov_> oh, seems they are using tweezers to short some pads and get into sd card mode... anyway.. read the threads :D https://forum.xda-developers.com/galaxy-s3/general/galaxy-s-iii-gt-i9300-hard-brick-fix-t1916796

23:54 <forkbomb> vakkov_: thanks! I was using that work as a starting point. Just not sure why it's failing at copying
