Mate, please, can you specify better your inputs?

I and other users can't install Dell BT drivers, because at installation it says it is not compatible with the device. Have you same behaviour? Or you be able to install the Dell BT drivers?

Why this different behaviour?

EDIT: Beside BT dell driver, i can't be able to install original teclast driver, in fact i got same message error! What happens here? Maybe different hardware on C9J8? Can C9J8 users tell me your BT drivers number? And your BT ID hardware? Mine is ACPI\RTK8723.

About 48Hz, i agree with you, but we hav battery drain on it! So no good! About battery life, how much is your battery life with moderate usage?

Wow, 10+ hours come viral.. i hope my estimated times is right, since windows no real meter like android. That is archived only on the 1st day i'm using this setting (48hz bios etc), other setting is, 1) turn of cpu virtualization 2) battery saver power option 3) performance/best battery intel graphics setting 3) lowest screen brightness

Now theres some changing, battery saver power option is disappear, intel graphics setting have to rise some setting because even youtube become stutter for lowest. Then screen brighness not lowest everytime, esp on office environment.

I'm not trying doing the battery test, but yesterday i'm trying to monitor the battery, still yeah sometime can archive 10%/hour sometime faster. I can say real life maybe 8 hours or more, or about that.

But seriously, before this i bought this tabby (nick to my x98, haha) to work, not even half of the day the battery died, but then i still have the juice even end of the day. I'm not using this tabby as main device. Just occasionally googling or researching yeah things like that.

Yup, this hub is crap. Mine died only after a day. Can be use in system (win/android), but not in bios. Now i'm just using normal compact usb hub with supplied otg cable.

Simply get usb 2.0 (not 3.0) hub at your local store (if convenience). Try to find powered-able if you plan to use external hdd (not trying it but direct hdd to otg simply not working)

I could not install the BT drivers as well and I also got the same error.

I'm also can't install the latest bt driver, but why? The installed driver is working fine.

And talking about bt, i have belkin fusive bt speaker, it's great for casual listening, but i can say stream from x98 is not that great, either on Windows or android, so i suspect it's because of Hardware. The sound from bt is loud, but rough & not really full. Best sound from this speaker, either you hate it or not, are streaming from ipad mini, then my wife iphone 5s & latest update Lumia 1520.

hy....many user are complaining of not getting the windows menu while booting through USB.....i had also ...i guess that there are three things that need to confirm...

1. Use rufus with MBR not GPT (and obviously FAT32)

2. USE x86 windows image not x64 bit...(i was doing the stupid thing for past two days)...finally downloaded supercowz image given on the OP.

3. Try to use powered USB hub (may or may not be the issue).

APart from this...if you have flashed the correct XML. There should not be any issue...also the 2 no is the one people are ignoring as many of us are having windows image and we are not bothered about the downloading same from OP. Please use X86 window 8.1 and the menu will appear for sure.

I tried to flash rom (almost all which I found: mirek190_v3.1 C6J6 / C8J7 / C9J7 / C8J7 (JCEspi2005) and original 2.0 from first page)

In DnX mode I see this:

Continued:

E: Installer device ignored

FASTBOOT INIT...

E: Failed to mount device '/dev/block/sda1' as installer partition using fs_type 'vfat'

and after succesfull flash I got trapped in tPad booting screen then rebooting, again and again

My device is C9J8 and I didn't made root :( (I didn't know, that I need it for the flash)

Is any way, how I can flash android rom (original or another) and rescue my new tablet?

X98 Air 3G temps are really good on the soc (At least my unit) I did a little test here Vs the Onda v116w with the same CPU. And after a 3Dmark test run the Onda throttles like mad at 88 degrees max and my X98 Air 3G only 51 degrees :) So Teclast are doing something correct when it comes to the little heat spreader and shield.

I recorded it here in a video https://www.youtube.com/watch?v=auXzxeXs_84 , trying to convince my seller on Ali Express it's not normal for a Z3736F to hit 88 degrees and throttle so much.

Your tablet must to be fully rooted.

Read carefully first page, dual boot developement, especially c8j7 instructions.

try again after you have a fully rooted tablet, with proper rom.

I get that with supercowz c8j7 rom, link in first page.

Good luck!

Yes you can use ntlite to integrate all drivers in both the system image and installation image on a usb with a windows iso writen to it using rufus with the correct settings. Then connect the usb to the tablet turn it on and select the tiny windows icon in the dual boot bios. You will be able to use the touch screen to complete the setup.

I had the exact same problem! :p

I tried different custom ROMs and different versions of the Updateifwi.apk but the updating process never finished! :silly:

(It should normally take only 2 or 3 minutes, by the way!)

I don't know what is the cause of the problem... :eek:

But the solution that I found was to update (or better... downgrade) to the official Teclast Android 4.4.4 V2.00 (

which you can get from here!

) and then use the included UpdateIFWI app and successfully flash the BIOS! :cool:

After that you can update to whatever Android ROM you want! :cool:

I hope it helps! :good:

You CAN use the mirek's files IF the system partition is large enough for the bloated stock system.img. Mine wasn't. Rebuilding debloated system.img would've required linux so I flashed mirek's ROM back.

Thanks my friend, i have read all posts, and in 6 hours i come to my house, and go patch my tablet.

Battery power drain in sleep mode - fixed

First I would like to say that it is not perfect fix but it works quite well and I am happy with it. Second I am using Windows 10 Technical Preview, but I am sure it would work well on Windows 8.1 too if not better. I am using tablet C9J8 dual boot, but I suppose it should work for all.

So what is it about? From reading some material on the internet and here I started to play with the settings and figured out how to turn on hibernation and when the tablet goes to sleep, after set period of time it hibernates. It is easy to do and to wake it up is very quick, a few seconds, so it is almost like a sleep mode and there is no battery drain :) There is one post dealing with that:

However I could not install any updates of Windows 8 on my system and besides that I have found another solution.

1. Enable hibernation as in the above post and create hibernation file on the Windows partition. Run Command prompt as administrator and type:

powercfg /hibernate /size 50

That will occupy 1GB on the eMMC for the hibernation file.

2. Run regedit and add the following registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FlyoutMenuSettings]

"ShowHibernateOption"=dword:00000001

"ShowLockOption"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power]

“CsEnabled"=dword:00000000

3. Reboot

4. Go to "Control Panel/Power Option/Change plan settings" (for the plan you want)

Here you can set how the display goes off and technically it is the same as the computer goes to sleep. (fig.1)

5. Go to “Change advanced power settings” and find “Sleep”. There you you go to “Hibernate after” and change it as you like. (fig.2)

You will also have the ability to hibernate your tablet through the start menu too. (fig.3)

That is it. What happens that after the stipulated time for the screen to go off the computer goes to sleep. After the time set in the “Hibernate after” the computer hibernates. You can set it different for battery or mains mode.

One disadvantage is that you loose the option to put computer to sleep through the press of a power button. You will be able only hibernate it or shut it down. So it seems that you can have either “sleep” or “hibernate”. However the wake up from hibernation is very fast and the main thing is that over night I did loose just 1% of battery. That is because it was running 20 min on sleep. It is not a perfect solution but it works well for me and hope that it may help some of you too :o

If you have some solutions for enabling sleep state trough the power button, please let me know.

I have tired and tried to backup the Air II windows image and flash it on my Air 3G, no luck what-so-ever! It seems Windows image recovery will not let me. Must be hard coded to the hardware ID.

Here is a hands on for anyone interested in the Air II

[YOUTUBE]g1Y8LyuqGOs[/YOUTUBE]

I have compared bios settings and they are the same. So I think, the Air 3G needs a new Windows bios to correct the cameras and improve the performance. The Air II feels so much snapper, I will benchmark it and see if it is really faster or it's just because it's running at 60hz. Good news on my OTG Hub, with the Air II it will charge and run usb hard drives and everything without stopping! Seems, my Air 3G is faulty? Or the OTG hub does not like the 3G as it seems to stop charging after a while.

So bottom line, the Air 3G needs a new windows bios and image . Teclast have the fix and the means, I just hope they release it! This Air II is going to it's owner in a few days...

This Teclast X98 Air 3G that my colleague has ordered from China, well it is not working with the Google Play Store.

Does anyone have a clean full restore ROM for this hardware? Rooting is not my thing and all I need is a clean ROM that I can flash over a not even properly installed Android 4.4.4 update (came with 4.4.2 but an update messed up all the software).

Nothing seen on the internet helps to fix this mess, the only way to fix the play store on my colleague's tablet is a clean install with a clean ROM, anyone out there got one or a link to download?

I don't mind the cheap price and my colleague did buy it also be cause it was inexpensive, yet what he has received, well this is a complete nightmare. A non-working product out of the box, and the shop selling these is not even taking notice of all the problems they generate by sending half finished products.
