firmware emergency update

Post by arris69 »

played around with the scripts from firmware update,
seems tv updtates (not encrypted) firmware from internal mmc card if boot procedure fail?
/mtd_swu -> /dev/mmcblk0p1

Code: Select all

sh -x /etc/Scripts/flash_update.sh
+ echo updating flash Images
updating flash Images
+ /sbin/ledon
+ [ -e /mtd_rwarea/shell_update_flag ]
+ [ -e /mtd_rwarea/swu_finalizer_complete_flag ]
+ echo Update image Dir = /mtd_swu
Update image Dir = /mtd_swu
+ [ -e /mtd_swu/exe.img ]
+ echo exe.img is not found.
exe.img is not found.
+ [ -e /mtd_swu/rwcommon.img ]
+ echo rwcommon.img is not found.
rwcommon.img is not found.
+ [ -e /mtd_swu/emanual.img ]
+ echo emanual.img is not found.
emanual.img is not found.
+ rm -Rf /mtd_rwarea/swu_finalizer_complete_flag
+ sync
+ rm -Rf /mtd_rwarea/shell_update_flag
+ sync
+ /sbin/ledoff
+ echo 
edit: seems to be the second stage of normal firmware update procedure

question is what's about the signature of this images. do the tv (re)generate it or are this images not replaceble.

zibri: time to brick and (hopefully) unbrick or bring to service the tv :twisted:

But, again, there is absolutely NO NEED to write to flash. There are enough mistakes in the firmware to allow to:

read on other forums that people are not happy with the builtin wifi-card
