[Teclast X98 Air 3G] Mark the Red:
I have the Air II. I only mentioned the X98 Air 3g link because you can download the FTPW.exe software from the same webpage at the Air 3g link. I specifically called out the 2.02 windows only bios for the Air II. You can get FTPW.exe from anywhere. I am just not going to do your googling for you (xda wont let me post links) .

Please note I thought I was pretty clear that you should NOT flash the x98 3g bios to an Air II. I even said to delete the air 3g with extreme prejudice. So long as you do not run the batch file from the link, and follow my instructions everything will work fine. Be ye warned.

Please note this is a WINDOWS only BIOS because the boot logo shows the Teclast logo next to the Windows 8 logo. Dual install Android at your peril.

Everything works 100%. I only use Skype so I cannot comment on the camera overall quality.

I reinstalled Windows 8.1 from scratch when I single OS'd by tablet. I did not like the 10 partitions the tablet shipped with so that is why I did it. Please note it is a chore to reinstall the drivers for windows 8.1 from scratch, but I am glad I did because I have no more Chinese text artifacts and everything is much, much snappier and smoother. Not to mention I have a single EMMC partition now.

It was showing the correct size and was still going flat in about 2 hours.

The other day in Windows it showed as the full 31000mWh and today it is showing as 21000mWh but as I said above even when it showed as the full 31000mWh it was still going flat after 2 hours, and since it is now showing as 21000mWh it hasn't really changed.

I have read that if you unplug the battery and then plug it in it has corrected it for someone on here:- I wonder if that is what is at play here?

[Teclast X98 Air 3G] 25gee:
Understood, I've been away from the thread a while so wasn't sure if it was dual boot or single as there was mention of switching between the 2 somewhere down the line?

I mostly use android over windows on my current dual boot setup anyway, so was hoping it may have been capable of both with a view to fixing some of the power issues related to booting in win8 as it dies really fast when in sleep mode :(

I can't say I have any chinese artifacts at all in the windows installation as it was a fresh install with the drivers manually loaded (maybe that's half the problem? but every driver I've tried, while working fine doesn't seem to fix the battery drain) so I tend to stick to android most anyway :)

but this thread - http://xdaforums.com/showpost.php?p=61719173&postcount=9792

it shows Dual boot? so if that is the case, can I not install both? I'm quite comfortable with partitioning and flashing the BIOS having done it countless times now, as long as the BIOS update is successful, I should be fine getting the rest going :) just wanted to clarify, as if this is indeed dual boot capable I'd like to try it simply to fix the Windows power issues during sleep as this is the only real gripe I have currently.

hello i want ask,how to resize the android partition,,example i want to instal android rom but just use 8gb,, please help me,thank you
[Teclast X98 Air 3G] 25gee:
Under partition tables is a partitions file (I believe it's XML, but it's been a while) from here you can edit the file to allocate the partition sizes you require when flashing the device.
[Teclast X98 Air 3G] raka-raka:
my android now is 20gb,so if i change into 8gb how about the rest? can i use it for windows?
[Teclast X98 Air 3G] 25gee:
Yes, if you leave the remaining space unpartitioned then you can install windows into this free space and dual boot, assuming you have a BIOS capable of dual booting.

My android installation is also 8GB and I have windows installed on the remaining space with a 64GB SD shared between them both, doesn't seem to cause any issues at all :)

When you install windows however, you will need to tell it to unmount the partitions for android under the management console, this can be found under Control Panel -> Administrative Tools -> Computer Management -> Disk Management.

DO NOT FORMAT THEM, simply change the assigned drive letters to nothing so that they are hidden from windows :)

If windows is already installed alongside android, you can possibly reflash the android partitions only, giving you unallocated space leftover, which you could then expand the existing windows partitions with using a tool such as partition magic or whatever you prefer.
[Teclast X98 Air 3G] Mark the Red:
The battery drain is 100% BIOS related. You will never fix it until you flash to 2.02. If you are dual booted,then updating your BIOS should be even easier than what I posted. Please refer to post #935. Not my post btw.
[Teclast X98 Air 3G] 25gee:
That is exactly the post I needed, thanks!

I'll give it a go shortly, hopefully it will fix the battery drain issues :) anything on top of that I can live with, of course I will try my best to get a 100% working device or as close as possible but this was a real annoyance :fingers-crossed:

That is core temp, the original user I quoted stated that the device started to 'Burn' if they mean physically I've never known that to occur.

The CPU core can hit 66-70C under heavy loads, but I have not known it to get too hot to hold or become uncomfortable, only slightly warm on the external casing.

Don't buy - no after service, shoddy goods

Here is a warning to those of you considering Teclast product. Bought my Teclast X98 Air II in the end of November on Aliexpress from Anna Fang Shenzhen OKQI Electronics Mall. The tablet arrived and worked well for about a week. After the initial testing and usage the digitizer started playing up. Basically it was registering touch all over the screen when none was present, the tablet would be idle and the touch clearly seen appearing. That would result in pages opening and closing, applications starting and shutting, etc. After a day of such unruly behavior I contacted the supplier and informed them of the digitizer problem, asked to post a video, which I did, clearly showing the tablet having a life of its own. I asked for the promised 12-month warranty replacement. Was told I have to sent the tablet back for assessment and repair, but advised it will take a few months. I asked to just be sent a replacement digitizer - they said NO. The postage would cost me $45, not cheap from NZ, so I eventually forked out for a new digitizer, it being the same price as postage alone.

A few days ago the tablet has suddenly just died - not charging, not turning on, no signs of life whatsoever. This time, being a repair shop, we had tested the components and the main board is no longer. Sure enough, I am contacting Teclast themselves for the warranty repair/replacement and OKQI as an authorized supplier for the same. NO REPLY FROM TECLAST, despite 2 emails being sent to every contact listed on a website. OKQI very reluctantly agreed to provide details for sending the tablet back, but not their address, after trying to basically talk me out of sending it back altogether. Here are the suggestions from them - to take the tablet to a local repair shop, maybe they can fix it (not sure why I should, it being on warranty), even after I told them that we are an electronics repair business and should not incur any extra expense, again, see warranty! Finally, after much back and forth we got to the postage. Again, a warning that it will take months with no guarantee, that they don't even know what will happen when I send it back, that i should not send by DHL or any other such carrier etc. HERE IS THE BEST PART - according to the warranty, THEY ARE ONLY LIABLE FOR THE LABOUR COSTS AND ALL THE POSTAGE AND PARTS COSTS ARE TO BE MET BY CONSUMER. Now, there is absolutely no guarantee it will be repaired and not cost me the price of a new tablet, after all I don't even have a say. The price can be anything, but if I refuse to pay it, who is to say they won't just keep my tablet until I do, or even after, as I said, there is no agreed amount, even after I provided the fault diagnostic. So $250 later here we are - a SHODDY PRODUCT AND EVEN SHODDIER SERVICE. STAY WELL AWAY, I WISH I DID.
[Teclast X98 Air 3G] MrRimmer:
Agree, you've had terrible service. I always buy this type of item with a view that the warranty is worthless. It's one of the reasons that the Chinese can sell well below the cost of an equivalent first tier product. Until they show the right attitude, they are always going to have to sell on price. Not that there aren't Western brands with shoddy levels of support...
[Teclast X98 Air 3G] beardedwonder:
This is the punt you take with Chinese tablets, I bought a Pipo tablet a couple of years ago and that's still going strong.

Did you pay with PayPal? I'd open up a complaint with them if you did.

Bricked my teclast x98 air 2

Hi all,

I'm using my teclast x98 air 2 dual boot only for windows 8.

Due to the limited reserved space I was trying to create some extra by deleting the android partitions.

It looks like I accidently removed a EFI? partition because the tablet won't load no more.

It only starts up and display's the teclast tpad logo.

Is there any chance i can reflash the entire tablet?

Grtz
[Teclast X98 Air 3G] 25gee:
Did you buy the device already shipped with dual boot? or did you flash the device to allow dual boot? if you are familiar with putting the device into the necessary mode required for the flash tool, then as long as you can still boot into this mode the process will be the same, the partition table XML can be used to define the partitions and sizes required and should re-build the partitions as necessary.
[Teclast X98 Air 3G] Rotjoeng:
I've bought the device when it was already dual boot.
[Teclast X98 Air 3G] 25gee:
If you hold volume up + power, do you get the option to select between which system you wish to boot? I'm not sure which tablet/BIOS version you have, but on the one I have I get the option to choose between android/windows as 2 separate tiles?

I'm not sure how you will go about getting the license for windows from the device (if you even have to, it should be stored in the bios?) but I feel someone who is more familiar with the pre-installed dual boot should assist here.

I used the old dual boot method, installing android first and using the bootable USB to install windows to the remaining space, if however you want purely windows, while this is possible, I have not personally tried it so cannot really guide you through the process.

If you can provide your tablet model number, I'm sure somebody here will be able to assist you further :)
[Teclast X98 Air 3G] enigma1nz:
Ah, but at the price point of $200 Teclast wants to be taken seriously, I could purchase a reputable brand for that amount and get a RTB 12 months or 24months extended for $15 extra.

---------- Post added at 01:06 AM ---------- Previous post was at 12:58 AM ----------

I would accept a punt on a $50 Pipo, at $200 it's no longer an acceptable punt to have it die within months of purchase with the promised warranty that is just not going to happen. I could order a reputable brand and have an extended 24month warranty for a tiny bit extra, like $15, and be looked after by a retailer. As I said - lesson learned, the funniest thing is, I loved that tablet and everything about it until now, so will stick to better brands and avoid Teclast from now on.
[Teclast X98 Air 3G] Rotjoeng:
It's a HG7N.

I tried the trick with the power and audio+. It loads the dual boot screen but the icon of windows is missing and the android icon is not working :) S*cks

If it was only NZ$15 more, then I don't know why you went for a chinese tab with the inherent risks.

FWIW there's little available in the UK that comes close to this Teclast tablet at the time I bought it. I paid via PayPal for a bit of extra security.

The massive thread here on this tablet and the 3G version show that it is pretty good and working for a lot of people.

BTW the Pipo I got was ~£130 (M9) a couple of years ago, not some throwaway single or dual core tab.
[Teclast X98 Air 3G] 25gee:
Yes, this is what I was going to suggest if that dual boot menu was the same, you can find the thread here http://xdaforums.com/android/general/teclast-x98-air-3g-tablet-9-7-2048x1536-t2913035

Please read the instructions

VERY

carefully as things can get quite messy if you go flashing etc unprepared, the section you want will be under the "Dual boot development" there will be a part about downloading the windows image/ISO and extracting it to a USB stick, you will likely want the unattended version which you simply drop onto a USB stick and need no intervention with during installation.

In a nutshell,

Grab the Iso

Put it onto a USB stick

Plug the USB stick into the tablet using the OTG cable

Boot into the dual-boot O/S selection screen

You should have a small windows logo icon, press this to begin the install

Wait for completion and continue with any necessary adjustments.

At this point (since I dual boot) I tend to go to control panel -> administrative tools -> computer management -> disk drive management, I then remove the drive letter assignments (NOT FORMAT/DELETE) from any "Non-Windows" partitions (usually all the android ones, but this may not apply if you don't install both O/S) so that they do not show up in the windows explorer, as this prevents accidental writing to or damaging or these partitions.

Install patches/drivers/software or whatever else you wish to do as it should now be safe to do so.

When I did this, the device was already activated and worked from the get go, I cannot say for certain what will happen in your case, but since you had windows already running, the license should exist in your BIOS and work correctly I believe.

[Teclast X98 Air 3G] 25gee:
This likely means you don't have the dual boot BIOS installed, it can be installed manually if you are comfortable flashing the device.

The dual boot I'm using is old so it'd probably be best to ask somebody about the newer version and how to go about installing that from scratch, I'm not sure if you need to go through the old method in order to upgrade or if there is a simpler means now.

Anyone else had problem charging this tablet ? I got mine today (64gb dual-os one), it didn't boot so I decided to charge it.

When it still didn't start after few hours at charger, I decided to use usb gadget to check amp pull from charger and it's... barely 0.02-0.06A, no matter what buttons I press on tablet. (tried 3 different chargers and usb cables) Even tried holding power button down for up to 2mins.

Now I'm running out of options, clearly tablet ain't charging but nothing I can do and sending tablet back to china for warranty is probably more expensive than whole tablet was.

Rotation is locked by default for some reason after updating, can't remember the exact setting but somewhere in the display settings there is a rotation lock setting ("Lock rotation of this display"). I think that was turned on by default for me.

Found it by searching for 'rotation' in settings. Maybe that helps for you....
[Teclast X98 Air 3G] hectorox:
There is not such option here on my side (I have the H5GN model)

I tried to enable auto rotate via regedit, but that did not work either...

Guys, I buyed that tablet on the first date of appearing and I have to say, I am quite disappointed... . Of course, the technical specification is absolutely acceptable (the price, too), but firmware, drivers,... that's horrible and getting on my nerves. Instead of a better working tablet with win10 (as it was praised in the Chinese official forum), a lot of things are not better, but worse... . So, if someone is thinking about buying this tablet, do not do it! Wait for the xiaomi mi pad 2!

For me, that was definitely the last thing I buyed from teclast
[Teclast X98 Air 3G] billbmsn:
The get the rotation option, you need to install the gsensor driver from the driver pack available here.

That was the only one I had to update. Otherwise Windows got the drivers right or at least working.

Essentially everything for the 3G will work on the Air II. So, I hang out and use resources and advice from this 3G thread.

Hi there,

i would like to ask for a small Help.

I Have Teclast x98 Air II dual OS (HG8N) and i Flash to "X98_Air_2_android_5.0_mirek190_v4.0." I used Manufacturing Flash Tools.

Android woks perfect, but I probably did some wrong step, because now, when I reboot the device, I see only Android. The Icon for Window (on starup) disapered and also not work "reboot to windows" Icon in Android.

How can I fix it?

Thanks

It seems that you chose the wrong XML file so you changed the partitions removing the Windows one...

You have to follow the tutorial of the first post of the teclast x98 3g thread.

BTW, you said that "X98_Air_2_android_5.0_mirek190_v4.0 " woks perfect! I have the same HG8N and cameras are not working and Android finally freezes with Lollipop Mirek's ROM.
