Hey <noscript></noscript>

I really don’t understand what the problem could be, as I have spent already hours, if not more, to try to find a solution, without success, and I feel quite desperate now… I know my USB dongles & hubs work well, but I don’t understand why I can’t manage to see them detected under the BIOS. I have thought for a moment about the BIOS Secure Boot function, but nowhere under the Bios I saw any way to disable the Secure Boot on this tablet…

On the YouTube videos, it seems to work flawlessly, and I respect the exact procedure they give, but on my device, it gives no result.

I wish someone, on this forum, could help me find a way to fix this, as having a full backup of my system & of all-partitions would allow me to deeply customize each partition without worrying.

Thanks a lot for your help, guys!

My C5J6 can detect the USB dongles. The UEFI BIOS can detect the USB dongles. Windows 10 detects the USB dongles. However when I set it up in the UEFI BIOS to boot from the USB dongles, it fails to do so. Same with Windows 10 with the SHIFT key + Restart option that takes you to the Windows 10 Bootup Diagnostic screen. UEFI USB 2.0 shows, and when choosing it, the C5J6 restarts, the USB dongle flashes rapidly several times, then it does not boot from there but instead boots into Windows 10.

I had the same objectives as you have right now but since this is my baby daughter’s tablet and the Android side of installs is still keeping me busy I have no time to tinker around that much anymore, having spend the best of a month trying to install a lot of apps and applying Link2SD to Android.

Maybe someone can help here or maybe if I can purchase another C5J6 in another sale.

Hi, I too am very interested in this aspect of our C5J6 devices, as I frequently use Linux (virtual) systems running from pendrives on both laptops and PCs, and would very much like to know if there is a way to call up a start-up sequence as with F11 on some computers. I am also wondering if anyone has installed Grub and a permanent Linux on their X98 Air 3G.

I tried several USB hubs but until I got a OTG USB hub I was not able to boot from a USB dongle.  Even with the OTG USB hub, I needed to tried putting the USB dongle into different port, and finally one port worked.

 

The picture below shows the brand that I used, and the port position that worked.

Thank you, Julyfish;

I haven’t yet tried a dongle, but from what you say I’d better order an OTG USB hub, as it’s bound to come in handy. I’m mainly interested in seeing if some version of Ubuntu or Debian can be run live.

Thanks. This looks extremely promising.

Hi Vasilis,

I’m sorry I couldn’t help concerning your specific request, as I don’t have, for now, enough skills in the mechanisms of dual-boot Win-Android devices. I wish I could have provided some help, sorry mate. I just know how to rewrite the Android part of this tablet with Mirek190’s custom Android ROM, as long as the partition tables of your device are NOT damaged, using the Intel Device Management sofware provided in this forum.

I hope you can find a way to fix your device 🙂

Cheers.

Did anyone work this out? I have a teclast x98 3G (c9j8) and have the same issue with being unable to boot from a USB stick, I have tried with both a powered and unpowered usb hub using an otg adaptor and also with just the usb stick pluged into the otg adaptor, in all cases i can see the usb drive as an option in the UEFI boot order menu (but not in the overide list) as well as in the windows UEFI menu but when I try and boot from the USB drive it always ends up booting my windows 10 install (on the internal storage), even if I disable that option in the UEFI menu??? I have done a lot of reading and while I have seen a bunch of people with the same issue, I have seen no fix. Please help :).

I have used Rufus to cvreate the drive and have tried both a 32bit install of win 10 (which I am currently running as my OS so it should work ok) and multiple different linux distros using the 32bit uefi workaround.
