Open backdoor for fixing bootloop situations
Some people have reported about a bootloop preventing the TV from starting through. The issue here often is, that the script invoked from within /mtd_rwarea/SamyGO.sh is getting stuck and preventing the exeDSP to start.
There are two key steps that should be considered when hacking your image, to avoid such situations or at least to open a external "backdoor" to prevent the respective script from starting.
Patching your exe.img
- Ensure that you send your scripts into the background when starting, by padding with a "&". Your changes in /mtd_rwarea/SamyGO.sh should look like:
export MAPLE_DEFAULT_PATH=/mtd_cmmlib/InfoLink/lib export MAPLE_MANAGER_WIDGET_PATH=/mtd_down/widgets/manager export MAPLE_NORMAL_WIDGET_PATH=/mtd_down/widgets/normal export MAPLE_WIDGET_DATA_PATH=/mtd_down export MAPLE_WIDGET_INCLUDE_PATH=/mtd_down/widgets/inc export MAPLE_PLUGIN_DATA_PATH=/mtd_cmmlib/InfoLink/lib export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mtd_cmmlib/YWidget_LIB export KF_SLEEP_READ=-2 echo 30000 > /mtd_rwarea/DelayValue.txt #touch /mtd_rwarea/DoPrintYahoo.txt export KF_NO_INTERACTIVE=1 export KF_LOG=/dev/null;/mtd_rwarea/SamyGO.sh& cd /mtd_exe/ ./exeDSP
- Include a check in your /mtd_rwarea/SamyGO.sh script, so that it will source and run a different set of commands, dependent on whether a specific file is detected on the USB-Drive or not. An example could look like:
# Open back-door for fixing boot-loop situations sleep 20 # Allow USB-stick to settle USB="/dtv/usb/sda1" # USB mount-point if [ -f $USB/usb.sh ];then echo "USB-File detected" $USB/usb.sh exit else echo "Running Normal SamyGO Startup" fi #"Your Lines Here" exit
