Original firmware appeared automatically

I have the Linksys 1200 ac running with lede 17.01.4
Very fine!
Then I tested nodogsplash and with only some wrong confit settings the router restarted 4-5 times and ended up with the power led blinking.
No access via Ethernet nor WiFi.
Restart didn’t help so I unplugged the power plug - waited and plugged it back in.
On Luci was gone and the original linksys config Interface appeared with the wlan config I had done before flashing lede.
How is this possible?
Does the original remain on the device if I flash lede? The router was without internet connection at that time.
I understood that I was overwriting the original firmware with lede so how can it appear right back?

2 flash partitions on that device.
By failing to boot several times it triggered failsafe and reverted to other partition which must have contained factory firmware.

Just reflash and try again.

nice. thanks,
I red it is fw_printenv and fw_setenv boot_part and failsafe.
Nice feature.
I am just wondering how a wrong config did make the router always dail to boot / crash. I have seen something "terminated" in the syslog before I was able to disable nodogsplash.
Maybe nodogsplash is not the right tool for me.
