[Help] BYD Seal 5 DM-i (DiLink 2) - Update Failed Error after custom firmware installation
Hi everyone,
I have a BYD Seal 5 2025 DM-i (DiLink 2).
After installing the firmware (Di2.2H_ota_26.1.1.2601212.1) from telgram "just_byd",
the update was successful and everything is working normally.
However, ever since that installation, my DiLink unit rejects all subsequent updates. Whether I try Chinese firmware from reliable sources (such as Di2.1H_ota_26.1.1.2602060.1 or Di2.1H_ota_26.1.1.2504290.1)
or even try re-flashing the same version from "just_byd",
the update bar flashes instantly, and after a reboot, it gives me an 'Update Failed' error.
It has been suggested that this issue occurred because the firmware I installed is actually intended for the BYD Seal 06, despite both models running on DiLink 2.
How can I solve this and force-flash the correct firmware for my specific model plz "
