I am still stuck on not being able to find/install the correct display driver on my HG9M...

I've done a fresh win10 installation. I have found drivers for all the "other devices" in device manager by letting windows search for the driver in teclasts driver package folder...

But no driver for display, sound and touch has yet been installed... Can anyone point me to the display driver?

Hang on.... Something is happening all of a sudden... I had a couple of exclamation signs on some system devices under device manager... They were called IC Atom something.... Updating the driver on some of them kick started something... All of a sudden more unknown devices appeared under the device manager... Including a VGA device...

Looks like windows is as fudgy as always...

Arrived today my new teclast air 3g 64gb c5j6

Dont know what to do first.

Update bios to 2.02

Update Windows to Windows 10

Update Android with latest Mirek's rom.

I've already take a capture of my Windows 8.1 serial.

I think:

First update to Windows 10 and Windows will see my serial key on the bios, then update bios with the official Android app to take no risk, then Mirek's latest rom.

Any advice to do it in the best order?

I have updated my bios to 2.02 in x98 3g 64gb c5j6 and keep record of serial key and also make backup of key with teclast bios editor,

But now after updating bios, I m not able to restore key back to bios with bios editor.

Even After whole process of restoring key to bios , my bios key is left blank.....

Secondly, is there any one able to install .net framework 3.5 in windows 8.1 with bling.

It always get error .

Third , I m getting error while using ussd codes in mike rom (android KitKat).

I can't use codes to check balance or check data balance
[Teclast X98 Air 3G] siezed:
Yea might as well do windows 10 first but you should save your windows 8.1 key anyways just In case, as for the bios vs ROM it really doesn't matter, I'd almost reccomend doing the ROM first just to familiarize yourself as the bios is the riskier of the two, but as long as you follow the right procedure the order shouldn't matter.

Best solution to test if the new base really doesn't work with C6J6 and similar is to shrink Teclast ROM to 1 GB. I tried and couldn't get it small enough to fit. I'm now calling all developers out there to debloat the hell out of that Teclast ROM.

So somehow, while deleting partitions, I messed up my tablet and it won't boot past the blue Recovery screen with error 0xc0000225.

WIn 10 auto rotation

EDIT EDIT! The original post is below, but I have solved it:

To make sure rotation works in windows: do all the below! Install the driver with the exe, do the registry merge. If you have problems like I did, enable rotation lock (see below) and set the service "Sensor Service" to automatic.

ORIGINAL POST

I just can't get my screen to auto rotate in Windows 10, and never have been able to since trying an Insider build. (It does rotate in Android.)

I've tried the drivers, reg keys, I even have to add "SensorPresent" in the registry under HKLM>Software>Microsoft>Windows>CV>AutoRotation to be able to see the Rotation Lock tile in action centre.

Could someone please look at device manager and tell me what it's installed as and with? I see it as Kionix Sensor Fusion Device. Driver date 13/05/2014, version 21.9.28.893.

Thank you!

EDIT: Looking at the device properties further, should there be a service running to allow rotation? There's something called WUDFrd that's referred to in the Kionix device properties but I can't find it under services. Again, if someone can type "services" at the start menu and run services - is it there? I see there's one called Sensor Service - "a service for sensors..." which mentions rotation in its description. It was set to manual and wasn't running. Starting it doesn't help so I assume it's not that...
[Teclast X98 Air 3G] tonica:
Hi everybody,

Last week, my Teclast x98 3G 64Gb (C5J6) arrived. I'm very happy with the dual OS, but it has some issues:

- The Wifi is too weak in Windows and Android, comparing with other devices. Sometimes, in windows I use a Wifi dongle, but no solution in Android.

- When charging and using Windows it shuts off, I will try the solution suggested by MindlessAutomata

- It has random auto-start up, specially when closing Windows.

Do you know if I update the Bios it will solve these issues?, specially the Wifi that is the most annoying.

I have read a lot of pages of this thread, but nobody complains about the weak Wifi reception, maybe it's a HW problem of my device.

I have the stock ROM, so I can update the Bios with the Teclast App. Is it the most safety way and avoid bricking the device? or Is it better an update with the PC?

Thanks for the forum and the excellent developers work.

Thanks in advance.

seized,

Try this image. It's derived from the lollipop final, but is rooted and has some essential apps bundled. I have been running it for basically a week with no lockups. If you are already running a lollipop build, you shouldn't have to wipe data. Use MFT to flash.

Updated link:

https://docs.google.com/uc?id=0B52NEACNrGeqOXh0eXpQTVRoWTg&export=download

original archive had corrupted system.img and would not flash

and if you want to remove the thermal messages, use the same installer I sent you last week. It works fine with this image

[Teclast X98 Air 3G] tecknight:
I have found that this fix will fix the MFT crash bug sometimes:

Download MFT timeout Fix

1. Extract archive to a folder on affected PC

2. Right click on 3-RunAsAdmin-ApplyCustomConfig.bat, select Run as Administrator

Batch file will apply MFT custom configuration in 2 INI files.

3. Launch MFT and flash desired ROM.

Running Android 5.0 and Windows 10 !

For anyone wondering if you really CAN follow the instructions on this thread

to install a rooted Android 5.0 ROM and upgrade Windows 8.1 to 10, I am happy to say YES

to both questions.

I used the provided tools and installed Mirek's Lollipop ROM.

Then I put the FREE download of Windows 10 Build 10240 on a thumb drive and installed it.

Using the Windows driver provided on this thread for Windows 8.1, I got everything working perfectly in Windows 10

and all my legacy apps also work perfectly.

BOTTOM LINE: If you CAREFULLY follow the instructions on this thread, YOU can achieve the same success.

The Teclast X98 Air 3G is my 8th Android or Windows tablet. I've rooted and customized every one of them.

So far, this is the BEST tablet and at $200 USD it is an amazing value.

Glenn

P.S. I did not flash the BIOS. My tablet boots into Android 5.0 or Windows 10 by simply pressing POWER button.

If I wan to change the OS, I hold the Volume Up button while pressing POWER. Then the choice window appears.

It will continue to boot into same OS unless I use Volume Up on next boot.

[Teclast X98 Air 3G] mirek190:
Are you sure everything is OK ?

No freezes ?

I'm starting think only problem is because of faulty gpu ( all sytem works on gpu to prevent flickering in some apps - in stok dosen't and on v3 either ) in next release I just underclock gpu to ~ 580 mhz like I did in 4.4 v4 + .

A bit lower performance is unnoticeable and worth it .

Bluetooth Keyboard doesn't work with Win 10

Hi All,

I have updated my x98 Air II to Win 10, and the Bluetooth keyboard doesn't work with it. The Bluetooth mouse works fine.

Both devices work well with Android.

BIOS update, Mirek ROM update and Windows 10 update all went well. Everything else seems OK.

Some references on the web indicate that early preview versions of Win 10 did not have Bluetooth support, others imply that Windows 10 on phones may or may not have keyboard support.

Is there anyone with the same problems ? Is someone using a Bluetooth keyboard successfully with Win 10?

Thanks,

Idk mirek i have my GPU set at 550 now and i just got another freeze, i was running nhpr app, it crashed then i opened it again and the whole system froze and i had to hard reset =( its possible im not actually changing it though, is there a way to confirm the gpu is actually running at 550? i just did a factory reset as i really do want full volume i use the speaker all the time its the main reason i really want to get this to work and dont just go with tecknights, well that and this is an actual air ii rom. Do any of the log apps work with this tablet? i tried before and could never get any logs to record, at least then i could see whats actually happening before the freeze, could be useful.

% jumps in the battery level

Hello, first of all, sorry for the bad english.

I have one problem with my teclast,both O.S Windows and Android, the battery levels suffer jumps(drops), for example, on android when the battery level reaches 50% it goes allways to 16% ALLWAYS.

On windows it goes from 67% to 26% in 1 second.

I think that it could be the bios.

Any help or sugestions???

No freezes so far but only been 20 mins or so. Ill report back at first freeze if it happens and what im doing. Mines an hg9m air2 64g on 2.02 bios btw.

---------- Post added at 12:51 PM ---------- Previous post was at 12:44 PM ----------

Its a common issue, and by common i mean basically everyone gets it, no fix yet, all i can tell you is its related to the battery reporting the wrong full charge capacity, and thats because the "design capacity" is wrong, which has to do with the fact the tablet has two batteries, a small and a big one, the good news is it seems to only be the battery meter itself and not actually affecting the battery or charging or battery life. The closest thing to a fix i can say is download batterybar for windows and when you boot up or come back from a sleep state check that and see if it reads 30000 or so full charge, if its less than that your meter will be wrong, and you can reboot or boot to android then back and usually it will be up to 30000 ish again. It also could be related to the system time of this tablet. It seems to just keep changing and i have no idea why, could be reporting to the meter that charging is taking longer or shorter messing up the full charge. All just theory though.
