I urgently need help to verify what files and in what order to flash to restore my GF's Note2:
It's a GT-7100 that is still on 4.1.1 and eMMC Brickbug Check app reports it as SDS vulnerable... original firmware, execpt for Exynos Abuse, SuperSU and AFwall+, but that was apparently enough to trigger "modified" state and so prevent OTA updates. Installing Wanam Exposed to hide modificatioon did not work, so we unrooted, but forgot to reverse Exynos Abuse fix. Now we're still unable to OTA, but without root as well
I think the next best step will be to flash to 4.3 via Odin and then apply saferoot from cosmyndemeter.
To prevent any warranty issues, I would prefer to keep the phone knox-free, which means that 4.4 update is not an option, and I need the botloader to keep to version mj5 or below.
I got N7100XXUEMK9_N7100VIAEML2_VIA.zip from sammobile.com, which seems applicable (region- and operator-wise), and BL_MJ5_DN3.rar for the unknoxed bootloader.
If I simply flash those two files, will that already trigger a reaction from knox (preventing any future BL-upgrades) or am I safe as long as the phone does not reboot between the two flash processes?
