I currently have a Onn. Roku TV 50' 4K. I have worked with Onn Roku Support and as well as Roku support to update the software, and it will not send out an email to register the device. I have done most if not all of the recommendations for similar issues: changed the wifi settings, used the hotspot on my phone, used a different email address, soft reset, and hard reset. I have done all those things with onn Roku support as well as Roku Support.
At this this point, the only thing I can think of is to do a manual software update using a USB Jump Drive. Here is the issue: I cannot get past the model number requirement on the Roku Software down load page. I choose Onn. as the brand and I have used what I think is the model number (2160p). This number was attained by researching similar TV as my Roku TV says the Onn. Model is "default"..... Which cannot be right. Either way, the model number mentioned above is incorrect as the Roku says that unrecognizable Model #. The Model Number that is on the back of the TV is 100012585.
If anyone can provide me with a model number that they have with a smilar TV that I can use to downlaod the software update that would be wonderful. OR suggest another fix, I am all ears. Thankful for any ideas beyond what I have tried.
