Looks like enabling SSH with this method doesn't work anymore with OEM firmware version 3.2.0.11. SSH doesn't get enabled after I uploaded a modified version of config. When I backed up the config again, the cron file and the scripts folder are gone. Maybe they started sanitizing config restore?
The number of files in the backed up config also look significantly smaller than what you guys posted. The backed up config file is here: https://mega.nz/file/VsUwiazB#bg2o_RaLamut-g9CmLU-FhUP012-5cnN3Sy2TT4RTpw. I tried looking for the endpoint for TR69 in the files, but didn't find anything.
