If you are staring at a red progress bar that stops abruptly, followed by a pop-up box containing the text — specifically noting that the exception was "patched" — your MediaTek (MTK) device is not bricked, but it is refusing to cooperate.

Locate the checkbox at the top of the partition layout grid.
The ROM file you downloaded is damaged, incomplete, or meant for a slightly different model variant.
