[Guide] How to use your own (full) fastboot

[BenutzerEinsZweiDrei]

(For my Kirin650 apparently the fastboot image provided didnt have all features.)
(this is only useful if your phone is soft or hard bricked)

1. Get stock rom and use Huawei Update Extractor to extract xloader.img and fastboot.img (they have to match)
2. Put them in Kirin650 folder of nvpotato
3. Use the following script to calc hash
4. change manifest.xml to your hashes
5. use nvpotato -> klick "disabled fblock" and uncheck reboot
6. check if bootloader ist unlocked, if not oem unlock and go back to 5
7. -> full fastboot access

use this script to calc hashes

import hashlib

def sha1_hash(file_path):
    h = hashlib.sha1()
    with open(file_path, "rb") as f:
        while chunk := f.read(8192):
            h.update(chunk)
    return h.hexdigest()

print("xloader.img:", sha1_hash("xloader.img"))
print("fastboot.img:", sha1_hash("fastboot.img"))
