Ah, nice find. I'll give a try this evening and do some passmark tests on it. ;)

Btw, I tested my Samsung Pro 64GB card and got about 24 mb/s read and 24 mb/s write, as expected.

I haven't tested it on my USB3.0 stick on my laptop, I'll post some screenshots of crystaldiskmark soon.

Got mine today.

I am not so familiar with Android, having only one before, unrooted.

Tried to use vroot, always failed. Then I noticed post #90, installed windows (Bing) according to this post, without rooting (combining information of posts #3 and #90). Just got it finished. Looks good.

Now wondering if changing to 8.1 Pro or even 10. We will see.

Thanks for everyone.

This was my seller and my X98 3G Air is perfect. http://www.aliexpress.com/item/In-s...Quad-Core-2-16GHz-android-4-4/1994183585.html

Make sure you get DHL or FedEx delivery otherwise your looking at a month for delivery. The express couriers should be 3-4 days, but due to issues in Hong Kong mine sat around for a week. Might pay to ask the seller if there are still delays in HKG.

Yes you can use ROM from android X86 project but teclast hasn't released kernel source yet.

So... no drivers for coocking another fully functional ROM.

Thanks for pointing it out, I made the change.

They all pretty much work really. The reason for the redirect is because they updated with a newer version, and so they set the old page to redirect to the new page. Sorry for the confusion, I'll change it to a direct link to the newest version.

To explain: on this latest page (http://bbs.teclast.com/forum.php?mod=viewthread&tid=258279&page=1&extra=#pid3208488) , they have 2 versions:

One full version with Office and other apps (bloatware in my opinion): http://pan.baidu.com/s/1hq6AbRI password: zgjl

One Lite version with only the necessities: http://pan.baidu.com/s/1pJFjq5P password: wy2q

Dang !

(Dang, again ! - I couldn't even quite something containing urls .. silly indeed !)

In my case all other apps, including various games and 3D animated wallpapers etc., have been working OK so far.

But when I tried with this test then after couple of runs the tablet froze :crying: (Better not to test with this ? :silly: )

Maybe this test is indeed more demanding than some other ..?

Overheating issue ? (Could explain differences between units. How well thermal pads and heat-spreaders are applied ...)

Update:

Now it runs again however many loops of the test. But there is 'thermal event - dimming lights' -warnings occasionally.

This seems to indicate that there is indeed thermal issues and probably many devices are 'near the edge'.

If the temperature rise is faster than the thermal throttling then crashes or freezes are probable.

I thank everyone in advance for their work on our tablet, it's great.

And I would like to ask if anyone downloaded the files from Baidu and would not be willing to give somewhere else.

from that Baidu wants to first download the app, which unfortunately resign, so you can download it.

thank you very much
[Teclast X98 Air 3G] darkpower2k7:
Yes please send me your phone number. How should I proceed and what should I backup before proceeding?

Is there anyway to avoid having a problem? For example send you my BIOS sothat you see if there is big difference with the other bioses you have. It would be a pity if I have a problem on my new tablet :)
[Teclast X98 Air 3G] keepfishes:
For your files, I have already used Dropbox links as much as I can. But for the links to the Chinese Windows Image files, I can't upload them to Dropbox because my internet is too slow, only 1Mbps. Would be good if someone can help me to download and host them.

I understand that it is difficult to download from Baidu because you need the downloader app. I am currently trying to get other forum members help to download it and to host it somewhere else. I cannot do it myself because my internet speed is too slow (only 1Mbps).

I hope everyone understands... Would be good if someone can help to download the files from Baidu and host it somewhere else, I will change the link in my tutorial.

USB charging

Any standard USB charger works equally well. They all provide 5V 2.2A.

(Some provide slightly more amps but may then damage some poor connectors.)

No (current) standard USB device is allowed to use more than 2A - So more capable supply won't help here.

Note:

I won't go here much into various non-standard fast charge methods breaking the 2A and/or 5V limits.

Those are really dangerous hacks - keep away from those. And don't mix and match those chargers with another devices.

(One example is Qualcomm's QuickCharge2 which can supply 12V 3A .. They have some secret handshake trying to protect standard devices :eek:

Then there is USB Power Delivery Specification Rev. 2.0 standardizing somewhat similar approach - but these are not on the market yet.)
[Teclast X98 Air 3G] keepfishes:
Okay as a temporary workaround for those unable to download from the Baidu link, I have amended the tutorial and encourage the download from the links in the first page, until someone is able to help to download and host the files from Baidu.

I have a clean version of Win 8.1 Pro x86 with drivers included and bloatware removed created with Wintoolkit, which is on my hard drive, and I want to share it with everyone because it works fast and smooth, but I don't have a fast internet connection, my upload speed is 20kb/s, hopeless...

---------- Post added at 09:50 PM ---------- Previous post was at 09:48 PM ----------

I realised that the key to charge quicker is to use shorter and higher quality cables. There's some guy on the chinese forum who did an extensive test with the charging cables on this tablet, and found that the length of the cable greatly affects the charge speed on this tablet...

im 99% sure that the dualbios will work, im ready to gamble 100$ on this, who want to bet ??? :P LOL

i think the release was

c6j7 win8.1

then

c8j7 android

c9j7 win8.1

and the new dualboot c9j7 too

since c9j7 is latest, it should cover and work on all of them

Hey do you have a download manager that can open multiple connections? How I did with my work computer was I used this: www.freedownloadmanager.org/

Then I copied the link of the download button into the download manager and started downloading at 500kb/s with 20 connections open.

You can try it.
[Teclast X98 Air 3G] PWMx:
This makes sense.

On the USB charger end voltage is 5.0V and at the battery end ~4.3V is needed, so only 0.7V drop is allowed.

(Assuming step-down or linear battery charging circuit, which is most common types. But even up-down converter doesn't help so much ...)

With 2A current this means maximum of 350mOhms allowed for all connectors and wiring in between.

That is not so much - especially with cheap cables and connectors ...

And this assumed the best case without any other power consumption at all !

My final image was 2.83 GB, I went into the advanced menu and unchecked a couple of boxes in compoenent removal... Just remove what you think isn't necessary... I don't think it'll make much of a size difference anyway.

What are the differences (if any) hardware wise between the Air 3g and the Air ii?

I've heard it's minimal and wondered why they were only selling the Air ii when I purchased it? anyway if the hardware differences are not too vast, is it possible to flash the x98 Air ii to dual boot? is there any info on this? do roms etc for the Air 3G work on the Air ii?
