Although these calculations are indeed entirely valid, you can choose whatever you like. 264 is a bit low for me (fonts sometimes too small) but if you have 20/20 vision you may like it. I chose an intermediate value. I have not noticed a big difference in fluidity.

Hrm, 646 for both.

Guess I won the lottery, still not too sure why I've got the low Unity benchmark but everything else is great.

Anything further worth testing in Android? I'm gonna get rid of it and go Windows only, but I wanna be sure there's no other information people need first.

EDIT:

Ok, it's all in chinese, is there a guide for changing it all to english?

I've tried mirroring what I'm doing on my laptop, but I'm not having any luck.

after i used 320 ppi long time but changed it to 264 ppi, i felt so much difference at scrolling. also letters and icons more visible and clear to me. 264 is the native ppi for such screen and resolution. but it is up to people of course, they can do what they want :D
[Teclast X98 Air 3G] microb77:
Ah makes sense! I will try that.

So now i have dual boot, and both android and win work well. Is there a way to make a full backup of both in one shot and to be able to restore from PC in case I break Android?

To get there I had to do the procedure twice of installing Android and windows and I would like to avoid that... Thanks!!

Hi, I've tried to update the firmware from stock 4.4.2 rooted without chinese bloatware to stock 4.4.4 via Teclast auto update but the process fail... I don't know why!

I've tried to install some apps come with stock rom as suggested in post #2 : ALL THE APKS COMES IN /system/app STOCK ROM (thanks to migui88) , but the firmware update fail.

So I would try to change approach and install before dual bios by toolbox but I have this doubts:

Sorry I don't understand this. No driver needed for flash dual boot bios by toolbox but I must rename what?

Ok,no GPS on the C6J6 with Air II bios, but 3G and 60 Hz display refresh are ok? Nobody try C9J8 dual boot bios on C6J6?

Anyone can help me to understand how can I update the bios via toolbox, please?

Thanks

DPI

I personally use DPI 240 because with this value is "virtual" resolution 1024 x 1366 in the chrome browser and it is optimal for the desktop version of the most websites.

Thanks so much! I just got my x98 Air C9J8 Build V100-20141216 today, and was wondering how to install custom android rom only? The windows part of my tab works great, I'm just trying to convert the Chinese android part. Do I have to root first?? I have read the threads and watched the videos, but they seem more specific to installing both parts, or upgrading from older bios. Thanks for all the help!!
[Teclast X98 Air 3G] SUMMERBREEZE:
it makes sense :good:
[Teclast X98 Air 3G] smartchip:
Thanks for the suggestion! It really does work well for browsing. Also noticed that this DPI setting prevents the odd 1px line on the left of the screen if you're using the Google NOW launcher. Yay!

Hi,

thanks to this fantastic guide on 1. page i managed to install dual boot on my brand new teclast x98 air 3g. Android work's fine, Windows too, but i can't activate it. The download of win8.1 with bing from the chinese did not work for me. May be it's for my bad chinese, but i just get a .exe file of a few MB from this site. So i downloaded Win8.1pro from Microsoft, integrated the drivers for our device and installed it with a retail key. Now i tested a lot of activators, but i just got a lot of male ware, windows is still not activated. Does some one know a working activator for Win8.1 Pro???

Ok, I have turned on hibernate mode in safe mode and it's working :P

But not in 100%... when i wake it up from hibernate and leave it for about 1 minute, it hibernates itself. It should go to sleep - in power option I have set 5 minutes to sleep ;)

Even when I press the power button and the tablet goes to sleep, in a few minutes when I press the button it wakes again from hibernate.

And when I wake it up from the suddenly hibernation, the touch is not always working.

So the hibernation is faulty and useless... maybe someone have resolved this problem? :D

A totally knoob question! Android bootlooping on C9J7 model!!!

I have the C9J7 model (Dual Boot)... Android can't boot anymore (bootloops), Dual BIOS working properly, as do Windows 8.1. My knoob question is, is there a way to factory reset Android (4.4.4 came installed), or should I flash Android again?? any help would be much appreciated!
[Teclast X98 Air 3G] mirek190:
Heh you are funny.

Ok

if you have boot loop you have to clean up data partition - 2 ways

- try run recovery mode - when tablet is off. Keep vol - and power button then should run in recovery mode. If not ...

- run DNX more - boot tablet to droid boot with the help intel manufacturing tool. - just unplug cable when boot to droid boot and with the help buttons vol + - navigate to recovery and accept pressing power button.

In recovery factory reset.

I too just want to flash your rom to the android side of a brand new dual boot ver. C9J8- 20141216 (android side still Chinese).

I apologize ahead of time, if I missed that post.
[Teclast X98 Air 3G] Cruxiao:
okay, one last question, does the 3g work under windows or is it still android only?

I've inserted the sim but had no luck getting it to work.

Xposed bootloop

Hello,

Can somebody please help me. I installed Xposed, and now my android is stuck in a bootloop. I have a dual boot w/ windows.

I read in this forum thread that many of you experienced this. Please help me get back out of the bootloop and back into my android (preferably w/o loosing my data on android).

Thanks for the help!
[Teclast X98 Air 3G] grigoris_a:
To disable Xposed, you'll have to repeatedly tap one of the hardware buttons (Power, Volume) on your device during startup.

If that doesn't work you will have to do it through adb

[Teclast X98 Air 3G] Frontier:
I mentioned the ROM, not the BIOS. The ROM link you gave contains the same files (system.img, recovery.img e.t.c) with the ROM release that was withdrawn.

The BIOS link you post is not available on the Teclast download page, you should contact the thread creator in order to update the OP.

Edit: flashed the updated IFWI BIOS, no changes with the one that my X98 Air 3G came (it's still the same version 5.6.5).

Edit 2: WARNING!! The new version from Teclast Website (v2.00-BD41) and the one on keepfishes post DOES NOT HAVE PLAY STORE installed. This ROM does not update to 2.01.
[Teclast X98 Air 3G] majkel_94:
I have downloaded v2.00 ROM from Teclast site and the files are the same (MD5 of files is the same!) as where in this thread from dev host download. There are only installers of ADB and flash tools + chineesee instruction with pictures :P
[Teclast X98 Air 3G] petruccig:
Hi mirek190,

follow some informations from a friend that keep an eye on the chinese forums (keepfishes):

<<Some comments say that it is still not true dual boot, and others say that it's true, but until now no one can confirm anything. I guess we'll just have to wait.

Teclast used the term "perfect dual boot device" but makes no mention of whether it is Windows virtualised under Android or if it is really running standalone. The deadline for the reviews to be submitted is the 30th of this month, so if they publish it at that time, we should be able to find out if it is virutalised or true dual boot that everyone is craving for.>>

I think it is better understand before what kind of dual boot is it and only after add the procedure.

Believe me, there are many people in this thread that are waiting for the response of the test of this elusive dual boot.

If is it true dual boot this device could become a killer tablet :cool:
[Teclast X98 Air 3G] G3n3R4L:
easy. first of all try to update all the teclast drivers, and then for the english language u have to activate the bing to pro, then try to google on how to changle windows 8.1 language because i dont speak chinese neither do u ... so we will take it like drawings.

second for the screen, once u install the video driver right click on desktop>>personalize>>display>>adjust resolution and then hit the "Allow the screen to auto rotate" ...

My $.02

ordered Air II few of weeks ago. It takes few days before they ship. After having tracking #, it will take few more days for it to show up in DHL. Another week and u will have it in the States. Bottom line: plan for ~3 weeks to receive it.

Mine was ordered with Android. Play store was DOA (4.4.2). I put it aside and after they released 4.4.4, did the update and rooted it. Next I was able to install the play store and finally, have a working tablet.

I am a heavy Surface Pro 3 user that does have years of Android experience (multiple phones, Asus TF100, Nexus 10). My take on the tablet in Android "mode": it is fast in terms of apps (page loads etc), but screen is a far cry from being smooth or responsive when it comes down to screen render time.

Mike is really bad. Has something to do 4.4..4 update. In 4.4.2 I was able to use voice reco of Google Voice with 100% accuracy. Now it doesn't recognize a single word. Not major issue for many, but I do like ability to speak search words etc. Bummer. Installed a voice recorder and the quality of recordings is bad, muffled badly.

On upside, the storage and WIFI performance seem to be nice. Charge time is reasonable (compared to truly horrid Nexus 10)

I am going to give it some time, may be they will release Lollipop for it. If not, I will probably do the Windows 10 install, just 4 fun.

Bottom line: dont bother with it, unless u r into science projects.

I just install all driver i need everything working except language

Thing is I don;t know how to activate bing to pro, Do u mean re install the whole thing with win 8 pro?
[Teclast X98 Air 3G] rashid11:
When it first came in, with 4.4.2, it was fine. it is after 4.4.4 update that it became unusable.

They either dropped the ADC to something like 4 bits depth, or .5 KHz sample rate or jacked up gain into near saturation.

Not aware of any market app that allow you to change these settings. I am sure Android has standard APIs for all of these.

Even if we get a recording app that rectifies it, stock Android apps, that rely on reasonable settings being pre-set, still wont work.

allways same question ...... dang .....

after reading this topic, and dint received yet my tablet i will go for pro ....
[Teclast X98 Air 3G] rashid11:
U r not going to brick it at Windows-level so to speak :) All and any versions of Windows 8 will work - but most will require drivers (teclast's own distro has em baked in) and different methods of acquiring licenses.

I suggest, drum roll, Windows 10. Why not ? Unless u need 100% rock solid daily driver, but then u probably would have chosen a different tablet to begin with ? :)
[Teclast X98 Air 3G] jacfry:
For the record:

I had to flash the bios using SPI programmer to be able to turn on the tablet. Charging whole night, disconnecting battery for a day, very long pressing of power button didn't help. I also wasn't able to flash the bios with the Winbond chip in the device. I had to desolder it, write the X98Air3G.bin and solder it back. Now everything works as before :)
[Teclast X98 Air 3G] G3n3R4L:
so right click on start and open device manager, then right click on each device or driver, and click update driver, then click on "Let me pick from a list of of device driver on windows", then click "browse" open the teclast driver u downloaded from the first post (the whole driver, not only some subfolder) and then next ... it will update and then move forward, one by one till u finish them all ...

[Teclast X98 Air 3G] smartchip:
Don't think they've started making keyboard + trackpad combos in a case for this form-factor yet. Most of the Chinese keyboard cases I've tried have pretty mushy keys, not great for accuracy.

Better keyboard cases like the Logitech or Zagg ones tend to work with the iPad magnetic catch or plastic enclosing the sides, so not really good for the Teclast (no magnet, wrong cutouts).

I've settled on a separate keyboard + trackpad combo and case. Mine:

The Motorola one looks nice, but don't know where I can find one:

my only problem is that there are no F-keys (F1-F12).

is it possible to map the function-keys (or multimedia-keys - dont know how to name the upper row of this keyboard) to F-keys (only in windows of course)?
[Teclast X98 Air 3G] smartchip:
This is a very nice one! The hinge is well built and really makes it feel like a laptop. Couldn't quite pull the trigger on it though, a little costly. I find that I don't stay in laptop mode enough to justify it.

Haven't done much research, but that row doesn't detect in the key-binding application I use. I always miss the "Esc" and "Del", key when using iPad keyboards in Windows.

Hi,

I've a big problem.. very big!

I've finally managed to do update from 4.4.2 to 4.4.4 stock stock.!

The application updateIFIWI is not present with the stock ROM, this is strange, so I've downloaded the apk from this link: ALL THE APKS COMES IN /system/app STOCK ROM (thanks to migui88)

I currently have all in Chinese language and I'm trying to set up dual boot bios via UpdateIFWI, but the flash lasts an eternity, remains the message "Upgrading, this may take a few minutes ...".

I tried also with the bios which theoretically should be with the stock ROM: Frontier Repository Air 3G 4.4.4 Bios, but the result is the same.

I'm afraid that if I power off the tablet I brick it.

What do you advise me to do? Have You any idea why I can not flash the bios?

Please heeeeeeelppppp:crying::crying::crying::crying::crying:
[Teclast X98 Air 3G] j.jusko:

Ok, I've just flashed your wonderfull ROM (with 8 Gb partition partition.tbl), so I'm sure my firmware is rooted.

I've follow these steps:

1. I've installed adb driver on my Win 7 64bit PC,

2.I've enabled debug usb on Tablet,

3.I've connected PC to Tablet via USB

4.I'm launching toolbox as administrator

But when press "f" key no effect, it show always the choose operation screen.

If I flash dual boot bios my mission will be accomplished for now.
