[Google Pixel 2 Questions & Answers] mr_krabbs:
I'm trying to keep my problem short. I had unlocked my bootloader for years now and I know the whole subject quite well. I decided to lock my bootloader and put everything back.

Because I was at the official beta of android 9 I decided to flash a factory image of the latest version.

Also the start in the new environment worked out. Therefore I locked the bootloader in the OS and did the same in the bootloader via fastboot.

Now I have a locked bootloader which I cannot unlock due to the os settings.

At boot I get the error: Slot Unbootable: Load Error.

fastboot continue ends in the same error

I don't recover from the same error either.

I cannot change boot slot because of the locked recovery.

fastboot works.

adb sideload not because I only hang in the bootloader.

Do I only have some chance to lock the bootloader or to cause some kind of factory reset?

fastboot getvar all tells me that slot a is unbootable...yeah i know. however b is not. So how can i tell my bootloader to start from B????

I've read a lot now but I'm at a loss. I am grateful for any help or advice.

I hope I don't have to take care of an RMA =(

I hope i missed some way to bypass this locked bootloader. im going crazy

Pleaaaaaase need help =( i spend paypal-beer for help :D
