If you use the latest incarnation of my instructions here: https://rob.themayfamily.me.uk/hudl/hudl-fixI got to this thread after following @TigerRob's tutorial It is a brilliant tutorial but I had no joy. Someone (possibly @TigerRob) mentions somewhere the possibility that the tablet is updating various other aspects of itself in the background and the process needs to be run through quickly. Mine had updated to the point where it refused to find the settings app and demanded an update to Google Chrome (which it refused to install).
Well, I had a little brainwave which worked for me. I shared my Phone WiFi and, once past the initial screen, switched off teh sharing so I could fumble through the rest, knowing that the HUDL had no possibility of updating.
So, with the stock, unadulterated factory firmware, sure enough, once I get to step 5 above, in stead of typing google app, I typed "settings" and I found I had the option to search ON the tablet. The updated version doesn't have this. Skip steps 6,7,8,9,10! Once I got the date set, I rebooted and went onto my home WiFi no probs.
I'm happy happy happy. I just got a new remote control for my IoT!
then you shouldn't suffer from that problem of needing to do things fast ... the instructions have been modified based on experience from a load of people, and as things a stands it should work for all but some devices that have the original non-upgraded firmware (and there is an the alternative mechanism which includes that 'might have go go fast' part that should still work for them).
Your suggestion is an interesting variation that I'd be happy to try to include, if that's OK with you?
I still recommend "upgrading" to my Custom ROM: https://github.com/remay/tmf-hudl/wiki
