I have RUT905 Serial: 05419029 HW rev: 0202 and first firmware from 2006 ( Idon't know exactly version).
I have updated firmware FIRST to the last 00.06.02 from April 2019.
After that in Firmware apperas about bootloader 1.0 which should be updated.
I have tried to update bootloader, also to the last, but I didn't succeed.
I respected intructions from https://wiki.teltonika.lt/view/RUT9xx_Bootloader_Upgrade#Bootloader_menu
The router still respond to ping and also webUI can be accessed.
I put the new firmware again and the router finished firmware update, restart and it works, BUT ofcourse bootloader remains 1.0.
What can I do?
How bootloader 1.0 affect functionality with last firmware?
I mention that I have made also downgrade firmware to oldest from site 00.03.832 but still the same problem.
