Unlocked bootloader, TWRP already flashed (or you can read boot via fastboot only).

| Capability | Works? | |------------|--------| | fastboot devices | Yes | | fastboot getvar all | Partial (many variables hidden) | | Read boot/recovery images | No (access denied) | | Read unlock code | No (requires exploit) | | Read serial/IMEI | Yes, via fastboot oem get-psid |

But what exactly is a Fastboot Reader? Is it an official tool? How does it work on Kirin-powered devices? And why is it specifically crucial for Huawei and Honor phones?

But always remember: with great power comes great responsibility. One wrong read or write in Fastboot can permanently brick your device. Always read twice, flash once, and verify every partition you extract.
