Because I am expecting malware to grow up to the point that it will be able to get root, then unlock, then turn secure boot OFF, and then overwrite the bootloader and radio in a ransomware form blocking the boot of the device until payment is done or something like that.Thank you for correcting me there LazerL0rd 2017-Mar-07 10:47 1 (quote) Dont think.By RusherDude, Senior Member on 25th December 2016, 08:20 PM.From there on, validating boot.img (kernels) and recoveries are checked via the lockunlock state of the device, and validating system is duty of the Verified Boot (dm-verity) feature on the kernel.
Unlike the old days with the Nexus One and its S-OFF achievement (for reformatting the nand and others), I havent seen any S-OFF or bootloaderradio development on any Nexus device from that point. Has been any exception for the N5X for some rare chance I know that disabling Secure Boot wouldnt be much useful considering there doesnt seem to be any radio or bootloader development at all, but the truth is that without the chance to flash and test it no development can appear from the nothing either. I honestly do not have any idea if by chance secure boot was disabled, anyone will jump into developing a better radio or more feature rich bootloader. Just wondering, has this been ever attempted or anything It seems that any HTC is attacked in this sense, but others arent, even if Nexus are considered development freely, the truth is that theyre all S-ON by default and no development of a radio or a bootloader seems to be in place ever. Mtk Secure Boot Android With RootIf It was able to happen with the Nexus One, why not for latter nexus devices And I dont agree to the point of we dont need Secure Boot disabled because we would be able to really brick our Nexuses, because you can still brick any nexus by flashing any (signed) bootloader or radio from another device, for example N5 bootloader into a N5X (and a ton of more examples with other signed images, and lets not talk about inside android with root. ![]() It would give out options not only to boot Windows, but also add features to the bootloader, repartition as we please (reduce system partition after debloating), adding a mechanism to prevent any bricking by adding a safe first bootloader sequence (like it was done for the N7 2012, via nv flashing if I dont remember bad), stuff like removing the damn bootloader unlock orange or other warnings (not only changing the images but also deleting the damn timeouts at boot), being able to add passwords for bootloaders, and a ton more could be done. That garbage partition is a GIANT security hole and for the worse it boots BEFORE the main cpu and controls everything, from the application cpu to the memory its using. Literally the radio controls the phone, its the most important partition, its FULL of backdoors (like the Replicant guys demonstrated for the Nexus SGalaxy S2), its FULL of unintended security holes (because no one develops for it decently, there have been some hacking conferences having fun at them) and its the worst we all having running on the phone right now. It doesnt matter your Android Version or security patch date, you have security holes that date from years ago opened and being probably exploited by goverments as we speak. There are great devs around, the bootloaders are usually decompiled to find exploits to be unlocked, for S-OFF and a lot of stuff. Secure Boot should be killed and development would take place. Sometimes I wish that the Nexus werent so unlocked and that we would need S-OFF to even flash custom roms, so a lot more development would appear, like it did for the Nexus One. ![]() ![]() The Following User Says Thank You to jugoslavpetrovic For This Useful Post: View. All is good while the bootloader is completely locked on and the radio is even more untouchable, literally making everyone able to spy on us.
