kodi beyond Jarvis 16.1 not loading on fire stick

I have a relatively new fire stick and have been running Jarvis 16.1 on it but my problem is I cannot update to a newer version.
I have tried 17.0, 17.2 & 17.3. I always uninstall 16.1 first to do a fresh install.
I loads but will not go beyond the ‘first run’….it goes blank after a few seconds. Then it does not load at all, but if I clear cache & data, once again it will load but again not past ‘first run’

I have 3.4 gb of 5.57gb
operating system 5.2.4.1 version 5.7.3 -17

I have 2 fire sticks, bought around 4 months apart and have no problem with installing 17.3 on that one

I have also tried various methods to install – adblink, downloader & ES file explorer

Is anyone else had the same issue, can any one suggest anything
