Reset Bitlocker

Is it possible to reset this device to factory settings? captainlinux8880（留言） 2024年3月7日 (四) 18:28 (CST)

It is possible. I can just format the system partition and install a new copy of Windows, or doing the factory reset in WinRE environment, but I don't need to 'cause I don't need another Atom tablet for use, also the performance of this tablet is not good. Probably I (or someone else) can get/calculate the Bitlocker password in BIOS ROM (I dumped the original ROM before batch a new one), then maybe the system partition could be unlocked. -WoodEar85（留言） 2024年3月8日 (五) 11:40 (CST)

你需要理解重置过程以及bitlocker的解锁流程。的确可以通过重置过程转储所需的VMK（CVE-2022-41099），但是这首先要求fTPM正常工作，但是显然经过固件重写之后fTPM对应的nvram已经不在了。--蓝色泪雨（留言） 2024年3月8日 (五) 13:17 (CST)

So that means, to unlock this BitLockered partition is almost impossible, only have a extremely tiny chance that the BIOS ROM contains the key (or some sort) than the partition can be unlocked. So, just RIP to the system partition. --WoodEar85（留言） 2024年3月8日 (五) 18:00 (CST)
