I don't know how but I managed to get it to work!!!

now I've got Mirek v.4.0... I thought it used Nova not Apex... but that's not a problem!!!

next step, new Bios... if I can understand how to save windows activation key...

thanks a lot!!!!!
[Teclast X98 Air 3G] tecknight:
Is the MFT recognizing the tablet now ?

If it is not, then launch MFT select File->Settings

Make sure your settings match these:

You need to select an XML file to kick MFT into "Ready to Flash" mode

[Teclast X98 Air 3G] tecknight:
Awesome job Mirek !!!

New Flasher looks really nice !!

In order to get the newly resized partitions, you would have to flash with partitioning ?
[Teclast X98 Air 3G] mirek190:
Yes

But not working that option yet .

Will be in v3 flasher ;)
[Teclast X98 Air 3G] juanmaasecas:
The only solution for me was to downgrade the bios. In 2.02 bios, the front camera is said to be the OV2680 but actually in our tablets it's the GC2235 version.

But now I'm remembering somebody said that flashed an air ii (no 3g) bios in his 3g tablet and could add the gps driver as legacy device. You could try that with the GC camera, I didn't, but I can assure you that if you flash an older dual bios version (I'm running 1.03 atm) the camera will work fine with the GC driver, because our camera is GC and NOT OV.

The ideal solution would be teclast to provide some updated bios versions tablet specific for each model, so we could flash the exact one depending on our hardware and be sure everything would work fine (touch, cameras, etc.), and not to be so scary everytime we flash a bios for a possible brick...

@mirek190 , thank you so much for the new rom version, but in my case I think I'll wait for the new lollipop update.

What are those touch problems some people has and you've surpassed with your new kernel? Is it just about improving responsiveness or reverted screen? My screen is OK but I think the responsiveness could be better. I watched a video that somebody posted here with 2 different units of the same tablet and one of them had a lot of more dots in the same touch testing app. Do you think it's actually a hardware "issue" or just a driver thing? Is it what you're fixing with your modded kernel?

[Teclast X98 Air 3G] tecknight:
The touchscreen problems he is talking about are covered in some detail here:

http://xdaforums.com/showpost.php?p=61810302&postcount=10069

Basically, the modified boot.img and kernel is required to make the touchscreen work at all on affected devices.

Something is obviously "breaking" since most of the devices with the problem worked normally until they suddenly stopped working normally.
[Teclast X98 Air 3G] siezed:
Thanks mirek for all your work, really looking forward to the next 5.0 =) Do you know if the wifi scan interval affects battery life significantly or not? i don't think it does but might be worth noting if you never had d/c problems you can even set the scan interval to 500 without any ill effects, i think its more if you get disconnected the scan interval makes you reconnect faster minimizing the impact of the actual d/c, but i could be wrong. One thing about 5.0, are you going to do whatever fix you did on 4.4.4 to make it so we dont get the screen dim anymore? tecknight did a great job with the tool to suppress the thermal message but it does still dim the screen, would be nice to play games at a brighter setting.
[Teclast X98 Air 3G] KYU15:
Testing now.

C8J6, did system only + wipe data.

Flashed with VID 8087 PID 09EF

Tablet recognized (or firmware says) as C8J7

The front camera is still inverted,

The mute sound icon on top right is still kind of stretched incorrectly. (see pic)

But hey, good work so far. I'm sure it's in some ways better than V4.0 :)

[Teclast X98 Air 3G] BoORDeL:
I do not do understand why asking.

Mirek statement in his v 4.1 post:

IMPORTANT

I recommend ( MUST ) wipe data because I changed a lots of things in virtual machine, apps and viper4android either will properly after you make data format.

For me it is extremly clear
[Teclast X98 Air 3G] mirek190:
About mute icon - forgot to change [emoji12]

Inverted front camera ? - c8j6 ?

I give you a path for it later today .
[Teclast X98 Air 3G] AntarcticPL:
Hi Mirek

thanks for the updated v4.1 rom.

On my Air II (HG7N) I still have the problem with the 'Google Play Services'. Immediately after starting f.i. the Youtube app the play services have to be updated, otherwise the app does not work.

After the update all sort of apps start crashing.

Am I the only one with this problem? Do I have to block the updates for the play services, but then the google apps are not working?

thanks for your kind reply!
[Teclast X98 Air 3G] ar2rc:
Can you describe how the downgrade bios 2.02 to 1.03?
[Teclast X98 Air 3G] mirek190:
Have you made clean install ?

After a flash and login or play store just leave tablet for 10-20 min and its update play services itself .

Anyway I haven't such problems at all .
[Teclast X98 Air 3G] daWyrd1:
mirek190,

excellent job with viper! i can hear youtube now. :))

Thank You Sir
[Teclast X98 Air 3G] mirek190:
That auto dimming is very annoying I know - the only device hasn't it is c6j6 and maybe c8j7 either .

I'm checking that and looks this one is in boot.img ( I hope is a module - then I could just replace it that from c6j6 but if is hard coded in kernel I can't do anything ....) or maybe find a proces and just kill it .

Turn off auto dimming is possible completely now but front camera stops working on c5jx and c9jx devices ( rear is OK )
[Teclast X98 Air 3G] juanmaasecas:
I said it briefly before. I downloaded the updated flash tools by Mireks and Tecknights, which are ready to flash 2.02 bios version. I put the updated flash.bat from Tecknights overwriting the older one. I downloaded the old dualboot bios file from techtablets and renamed it so it had the exact same name as the newer 2.02 bios (which I put outside). The goal is to keep the program working witouth touching it and just change the bios to flash... If you prefer to avoid doing all this stuff, just download this file:

https://dl.dropboxusercontent.com/u/30899299/FLASH202 modded to flash bios 1.03.rar

It's all you need and prepared uploaded to my dropbox account.

1. Start the tablet in Android mode.

2. Make sure all the adb drivers are installed. Connect the tablet to the PC via USB.

3. Extract the downloaded file and execute flash.bat

4. Press enter to proceed

5. Pres 2 to flash bios without repartitioning.

6. Keep the instalation.

7. When flashing finish, you can read in the CMD windows that you need to turn the tablet off. Do it by pressing power button for 15s or so.

8. Voilà! New (old) bios flashed.

It's 1.03 bios version. It could be fine if we had some more dualboot bios version to test...

I've looking into the bios in techtablets and there are only this 2 different dualboot bios (1.03 which is repeated and 2.02 which is repeated too...).
[Teclast X98 Air 3G] benbraun322:
Wow Mirek thank for all the awesome work.

Any idea when we could get these features implemented into a Lollipop ROM?

From my BlackBerry Z30 or Teclast X98 Air 3G (C8J7)
[Teclast X98 Air 3G] AntarcticPL:
Hi, yes I've done a clean install (format data and cache). I'll try again this evening, but don't know what I'm doing wrong. It indeed updates play services itself, but starts crashing after the updates and a reboot.

thanks!
[Teclast X98 Air 3G] mirek190:
I think it will be ready for 2 weeks .

Still a lot to do with it ....path completely 2 big memory leaks , repairing framework , system ui , porting all features from 44 c 4.1 etc .
[Teclast X98 Air 3G] The_Foxx:
Do you have any future plans for doing 5.1 or 5.2 (when released)?
[Teclast X98 Air 3G] mirek190:
Yes I do - when I made teclast rom 5.0 enough good for me [emoji1] then I'm going port aosp or cm.
[Teclast X98 Air 3G] tecknight:
Mirek,

Mine is C8J6 and I have never had auto-dimming occur. Does it happen in lollipop or just Kit Kat ?
[Teclast X98 Air 3G] mirek190:
In that case that thing is on c9jx and C5jx devices only - belive me very annoying - if I'm not solve that fully then just use kernel from cj8x or c6jx and my front camera won't be working - I can live with it .

On android 5.0 - do you have auto dimming ?
[Teclast X98 Air 3G] tecknight:
You are not talking about sleep after a certain amount of inactivity, are you ?

You are talking about thermal based, auto-dimming, correct ?

Mine is not dimimg in lollipop, no
[Teclast X98 Air 3G] mirek190:
That auto dimming is in video and games that uses gpu .

For instance - video works on gpu ( acceleration ) if scene is darker then screen getting darker too - this not happen on software video .

And is very annoying on youtube , in MxPlayer you can use software acceleration then is OK .

Hi Mirek190

After flashing the ROM v4.1 KK, I mistakenly restored with titanium backup my old version of Viper4 FX and my old settings. How can I do to get your new configuration and your settings?

:confused:
[Teclast X98 Air 3G] lysie:
What is the latest recommended guide to transform the teclast into windows only?

I already have dualboot up and running and thoght about just deleting the android partitions. But thats not a clean way in my opinion and i´m not sure if i can add the free space to my C partition ( i think i´ll have to create another partition for that? )

The easiest way i found is w ww.youtube.com/watch?v=sNLPm0EQqA0 correct?

But what about wimboot? Or should i wait for win10 because they said they´ll change things up anyway to reduce the install size.

Also is supercowz 8.1 pro .iso recommended? Comes preinstalled with the drivers i think?
[Teclast X98 Air 3G] szaman89:
Wipe and flash 4.1 again
[Teclast X98 Air 3G] mirek190:

- Flash again with wipe

- try setup viper4android by yourself and check if works OK .

Thanks, I tried all three. Everything remained the same.

It's probably because my tablet although is C8J6, is identified as C8J7

Hi Mirek, where is coded this setting please ? I can't dl your ROM right now because I'm abroad but I would like to test it as I've got some wifi issues.
[Teclast X98 Air 3G] tecknight:
Chris,

It's in /system/build.prop

Find the line containing:

wifi.supplicant_scan_interval=

and change the value to 90

Then save build.prop and reboot

Note: you will have to remount /system as read-write before you can change the file, since /system is mounted read-only by default.

you can remount system read-write by typing:

mount -o remount,rw /system

from a root shell. You can remount /system read-only after you have edited the file with this command:

mount -o remount,ro /system

also from a root shell.

juanmaasecas,

Could you upload the 1.03 dual boot BIOS, cuz I have an idea about how to mod the 2.02 BIOS to make it work with your camera. In fact, I think I could modify the BIOS so it would work with both camera types. I have been analysing the 2.02 BIOS and and I found several unused device entries that are not being used in 2.02 and I think I can overwrite an unused entry with the correct info for the camera on your devices.

You would probably find it interesting that BIOS 2.02 already has 8 different GC2235 configurations defined--apparently none of them match how the camera is setup on your tablets.
[Teclast X98 Air 3G] juanmaasecas:
I got 1.03 bios from tech tablets. Com.

Here you are de original link

http://techtablets.com/download/teclast/x98_air_3g/bios_files/dualboot bios tested C6J6 and C8J7.7z
[Teclast X98 Air 3G] tecknight:
Thanks.

One more thing.

Could you give me as much detail as you can get from device manager about the address/configuration/PNP properties of your GC2235 ?

I need to identify the device profile in 1.03 that is correctly identifying your camera.

Once I do, I am going to transplant it into the 2.02 image.
[Teclast X98 Air 3G] juanmaasecas:
By the way, has anyone with the camera orientation issue managed get them working fine with the latest graphic drivers? I want to keep my graphic drivers updated because of possible improved performance, but o can only get them working well-oriented with the old drivers. If only I could know which registry entries modify orientation, or at least just make working only the old Intel imaging driver with the new graphic drivers... (when I install 2013 October imaging driver with the newest 2015 graphic drivers I get a BSOD in windows 10).

Finally, I find windows 10 quite slow, lag, transitions aren't fluid, etc. I have also a Voyo a1 (z3735d and 1280x800) and its much faster. does windows 8 work better on our teclast? or is it slow because of the resolution? I have a c6j6, which is always quite warm but doesn't hang because of temperature or have screen dimming (until now...).

Guys, if you need more support from manufacturer you should buy Asus, Samsung, LG or other famous brand.

This is one of the reason why this tablet is so cheap. ZERO support. They just release another models and forget about Air 3G.

I have Win 8.1 for some time now and only one problem still remain : 48 Hz screen. Well, i don't play games on tablet so it's no big thing.

This tablet is excellent price to functionality ratio.

Yes. It will happend because when the OS is activated there is an entry in BIOS where is stored the information about legal activation.

When you flash new BIOS you have to activate it again but you can't do it with this tablet because it's pre-activated, you don't receive a key on paper to enter in a textbox.

Any news whether Win 8.1 in Teclast dual system is 64-bit or 32-bit?
[Teclast X98 Air 3G] HDtracer:
I just dont understand the fascination with the whole dual boot thing in this thread.

If you want a windows tablet, Teclast has given at least 2 options to have one, either Air 2 or flash the Air 3G.

To me its the same a buying an Ipad and complaining that Android wont dual boot on it even though they both run on the same chips.

Microsoft and Google have both said recently that they do not/ will not officially support dual boot systems, so the fact that Teclast is even looking at it should be considered a bonus.

Considering IOS, Android and Windows on a tablet have sooooo much in common functionality wise, to me you should just pick one and be happy with it.

Sorry if this comes across as a bit cranky but I just read through 6 pages of wheres our dual boot :crying:

[Teclast X98 Air 3G] petruccig:
I think that for some uses Android is better, for others is better Windows.

Maybe Android is better for multimedia use because much more "touch friendly", while Windows maybe is unsurpassed for a business uses.

I think also that Windows 10 could be a turning point in terms of usability with fingers, I refer to the possibility of switch from desktop to tablet mode .
