@Nuno_Jun ,
Thank you very much for your continued attention to this issue. We have already fixed the problem. We may release the update next month (or possibly update directly to Android 16 later this year). You are an important customer to us. Now, we are providing you with a convenient update method using a USB drive. You can go ahead and update the version. I have recorded an instructional video. Hope this helps you.
I applied the given update and confirmed that everything is working fine. Thank you for your support!!
