Hey Rob, I have an Onda v975s v1 tablet (which was cloned by a Romanian company called Allview) and I've tried all the v1 ROMs uploaded by you, but the wi-fi doesn't work.
From my understanding is that I need a 3.2 or older ROM for the v1 975s tablet.
Could you please look and see if you can find it somewhere?
I believe this issue was answered in your other direct messages.
Yours is not Onda device ... period ... any firmware you install is at your own risk.
Please refer to duckduckgo.com search engine results, as it contains much information and links to other techie sites and some post links containing download links .... the research is yours .... confirm same CPU, RAM, Storage, Touch panel, Video and Screen.
WiFi / BlueTooth has always been an issue with these cheap ( disposable ) Chinese devices.
AFAIK Win 10 drivers were compatible... at the time of release .... Win updates may no longer be operational ( ie: may require you disable device driver automatic updating ).
So I have an Allview 3 Speed Quad HD which is a replica of the Onda v957s v1 tablet, but I think it has some modifications or something. Because I've tried all the ROMs I found (4 here and another Allview ROM) and the wi-fi never turns on. Is there any way I could add some wi-fi drivers maybe?
