Dear Anna,
We solved such problems by writing python script for automated rename of files corresponded to ETM+ thermal bands before processing in Grass as we often have to work with many images.
in the case of single images it is not a problem to rename it to format LE........B61 and B62. Then after ETM+ data import to GRASS, i.landsat.toar work properly.

Best regards,

Maria V. Kozlova
