Some Onda V975i Tablets Deficient For Windows 8.1 Upgrade

Thanks to Marcus in Comments, we learn that some of Onda’s V975i production run has a design that can’t easily upgrade to Windows 8.1.

From a thread at slatedroid:

It is now necessary to solder on two resistors to be able to flash win8.1 bios properly without the HDMI/Screen bug. This is why Onda has delayed the Win8.1 update as they were probably trying to find a way to do so without a hardware modification. Unfortunately, it is pretty much confirmed that you need to solder two minuscule resistors onto an equally tiny spot to be able to flash win8.1. Most of us have really horrible soldering skills. Luckily, if you read on, I’ve come up with an alternate solution that will enable the majority of us to perform this hardware mod with minimal skill.

Like most tablets these days, the Onda V975i isn’t made to be opened by ordinary people. This isn’t an option for people who are fearful of possibly destroying their tablet. For those who don’t want to ship it back to China for a swap, I’d suggest trying to sell it on ebay or Craigslist (and clearly mentioning no Windows upgrade; some people will be fine with just Android) to defray the cost of buying a brand-new V975w. That sucks but this is the risk with Chinese tablets — and especially with Onda, a company that now has a history of fast hardware revisions.

    Yeah, or you could mention that with a few bucks and a couple of weeks waiting time, you can order the parts on places like eBay and then perform the hardware mod on the slatedroid thread. It looks really simply and straight forward.

      That’s why there’s the link to slatedroid, so people can see that for themselves.

        I saw the “Like most tablets these days, the Onda V975i isn’t made to be opened by ordinary people. This isn’t an option for people who are fearful of possibly destroying their tablet.” That isn’t very encouraging.

        It’s not supposed to be!

    There’s a fix that doesn’t even require soldering. Just use a pencil.

    hey mike has there been any new coverage of the v975w? judging by the company theres a chance of even that getting new hardware revisions or updates due to being unstable now.

    I was sure that I will buy v975i until I’ve read about possibility of v975w. Should I even be thinking about Windows 8.1 on 200$ tablet? What do I get which is not possible on Android?

      Ah, excellent. I’d already swept YouTube once today for V975i vids, so this popped up afterwards. Will do a post — currently busy with another Xiaomi one. Thanks.

    Mike, is there any way of differentiating between which v975i models are able to install windows 8 without hardware modifications?

    • mikecane

      If there were, Onda would have said so. This same thing popped up with the Chuwi V88. Some people could not easily use Oma’s ROMs due to hardware differences. There’s no run of device serial numbers that distinguishes internal differences.

      EDIT to add: Onda has published device serial numbers, but they’re in the download itself. Post coming.
