Cause : The modified partition file size was modified without adjusting the block configurations.
Manipulating firmware involves significant technical risks. If the internal structure of a payload.bin file is not perfectly recreated, the device's bootloader or update engine may reject the file, or the device may fail to boot (a condition known as "bricking"). Most modern devices utilize verified boot processes to ensure that only officially signed firmware can be executed. Modifying these files typically requires an unlocked bootloader, which often voids manufacturer warranties and can alter the device's security profile.

Many "exclusive" repacks sold on forums are actually Trojan horses themselves. An attacker selling a "FUD Meterpreter" might actually repack a (Remote Access Trojan) that steals your own cryptocurrency wallets or logs your keystrokes.
If you are a defender, you should configure your proxies to block uncategorized domains and monitor for HTTP GET requests to /raw or /payload endpoints with binary responses.
