Content tuya_start.original.sh

[burnbabyburn]

Hi,

can someone post the content of the original tuya_start.sh? The if clause got ignored while restoring back to factory and thus it has been overwritten :(

this is my tuya_start.original.sh

Thank you very much @frtz13 I am currently dumping flash to recreate a working rootfs to escape my bootloop. I'll report back to document the recovery steps if one didn't make a backup and close this issue afterwards :)

Maybe you could also dump ssh_monitor.original.sh

[frtz13]

here we go: ssh_monitor.original.sh

#!/bin/sh
SSH_FAILED_CNT_FILE=/tuya/ssh/cnt

sleep 3
mkdir -p /tuya/ssh

failed_cnt=0
sleep_time=0

if [ -f "$SSH_FAILED_CNT_FILE" ];then
                failed_cnt=`cat $SSH_FAILED_CNT_FILE`
fi

if [ ! -z "$1" ];then
    test_login_flag=1

        killall tuyadropbear
        sleep 1
        rm -f /var/run/dropbear.tuya.pid

        let failed_cnt=$failed_cnt+1
        echo $failed_cnt > $SSH_FAILED_CNT_FILE

        if [ $failed_cnt -gt 5 ];then
                let sleep_time=432000
        elif [ $failed_cnt -eq 1 ];then
                let sleep_time=90
        elif [ $failed_cnt -eq 2 ];then
                let sleep_time=300

thank you again :+1: i just needed to hardcode the last line in tuya_start.sh to ./tyZ3Gw /tuya/tuya_user1/ /tuya/def.cfg & get the gateway up and running again
