Hi,

I am a personal laptop user. Recently I have reset my laptop, reset was successful to reset windows in C Drive. However, my D & E drives got locked by bitlocker automatically. I have spoken with Microsoft about this problem and they suggested that this error was caused due to a glitch in TPM. They asked me to seek Lenovo's help and downgrade my BIOS to earlier version. But unfortunately, Lenovo restricted downgrading BIOS recently as a recent change in their policy. Now I am stuck with my personal pictures/ files sitting in locked drives. Hope you could help me in recovering my data. Please let me know if you can help me in any way. Thank you so much in advance.
