[Samsung Gear S3] adfree:
Tiny exercise... :rolleyes:

With BQC2 FTMA Combination Firmware... Tizen 2.3...

3 x dumping rootfs...

dd if=/dev/mmcblk0p14 of=/opt/usr/media/BQC2_rootfsDumpFull_p14.bin

sdb pull /opt/usr/media/BQC2_rootfsDumpFull_p14.bin

rootfs.img from Firmware package is few Byte smaller as dumped rootfs partition p14...

But IMHO I can ignore this... for now...

Round 1.

1 : 1 same like inside rootfs.img

COMBINATION-FTMA_R760XXU2BQC2.tar.md5

Round 2.

After Command:

verityctl --verbose disable

But BEFORE Command reboot

1 Byte differ :D

Round 3.

After Command:

reboot

After Rebooting I know more Bytes are different... I have to wait for Transfer to my PC...

Edit 1.

Additional step after Round 3...

sh-3.2# dd if=/dev/mmcblk0p12 of=/opt/usr/media/BQC2_systemDumpFull_p12.bin
323584+0 records in
323584+0 records out

sh-3.2# exit
exit

sdb pull /opt/usr/media/BQC2_systemDumpFull_p12.bin
pulled BQC2_systemDumpFull_p12.bin 100% 158MB
1 file(s) pulled. 0 file(s) skipped.
/opt/usr/media/BQC2_systemDumpFull_p12.bin 549 KB/s (165675008 bytes in 294.216s)

Trying to identify where else data about verity crap is stored... :eek:

Edit 2.

Seems I can now use 1 Byte change... instead my old method:

Short tested with BQC5 rootfs.img...

I have injected su and verityctl from FTMA BQC2...
