[Teclast X98 Air 3G] kinhvanhoa:
Thank you so much for sharing this rom.

I've just flashed it on my AIR II device [ Completed the Dual Bios installation but the Camera problem occurred ].

1. I followed FAQ 8 instruction for flashing Android ROM without affecting the installed Windows.

2. On IMT (Manufacture Flash Tool) I chose " flashC6J6_5G_500MbCache_JCEspi2005.xml " in your Rom for flashing IMG.

- Did I have to chose "flash.xml" ?

3. Flashing the Rom was successful.

4. It's super faster than the previous Lite Rom. The rom works just as stated: No Chinese apps. Google Play works fine.

BUT.... :confused:

1. Camera is still working UPSIDE DOWN.

- Weird. It's then another problem? or due to Hardware difference? Mine is AIR II not air 3G.

2. A good Spanish lesson this time rather than Chinese. ^^

2. OMG....My windows partition is gone.!!! It still shows the Dual Booting screen, but no Windows Logo to choose.

It seems gone.... How can I recover it? Do I have to do all process again?

Is that caused by a partitioning error?

Did I miss something terribly? How could I do clean reinstallation? Just follow the Dual Bios installation again?

Thanks.

Correct Values

Oh, I'm using the values from post #4 all the time. I was able to flash Supercowz android and to install windows flawlessly. But since then the tablet cannot be charged as long as it is running, and it is only detected by the host PC as long as it is in DNX mode. Also no data transfer can be achieved between Android and host PC.

But USB sticks, hubs, mice and keyboards work correctly under both OS on the tablet.

[Teclast X98 Air 3G] Cozla:
Sorry to tell you, but you didn't followed FAQ 8 instruction :(

8) FAQ:

A: If you want to reinstall Android only (leaving Windows unharmed):

One way is to flash just "system.img" through the Intel Manufacturing Tools (try this way first).

Download from here the zip named "ONLY FLASH system.img": http://1drv.ms/1s8dci8

Replace the "flash.xml" in your ROM folder with the one in this version.

Then flash as per normal using IMT.

This "flash.xml" will instruct the IMT to flash only the "system.img" file which is Android OS.

You have to install windows again.
[Teclast X98 Air 3G] jcespi2005:
As previous user said, using the XML flash the entire system, and modify the partition table with new values, so you need to reinstall Windows again,sorry... thoug was clear. The XML you used is designed to let 5Gb to Android (downing cache to 512Mb and System to 1024Mb), and the rest to Windows.

Good to confirm about Google Play ;D And answering to the other questions:

1. Camera works fine for me, with same files, but sounds to me like some app/framework don't work fine as deodexed. Need research, and someone more to confirm on a Air 3G model.

2. I'm spaniard, but easy to change to any other language ;)

2. You know why now... sorry again... just boot and reinstall windows (hope you haven't important data without backup).

Cheers
[Teclast X98 Air 3G] ImJamIN:
I think that camera work only with that version of Android of tablet's version.

So c6j6 to only c6j6, c8j7 ti c8j7 and so on

I hope that c9j7 can work for all.

P.s.: can you give me instructions to how to deodex , zipalign root etc that have you used? (Only for this passage) thanks
[Teclast X98 Air 3G] jcespi2005:
As a general method just decompile the IMG using ArchiKitchen, and deodex/zipaling inside. After that, subs files from ArchiKitchen project on mounted System volume.

NOTE: For deodexing theres no need to use nothing, cause files inside the ROM have class dex inside APK/JAR, so just can delete the .odex files... curious.

mmm perhaps a change in build.prop helps the camera works fine... can someone try to edit the C6J6 string with his model? just to discard this point...

Hi everybody,

I'm installing dual boot and i have problems to get a win rom:

- WINDOWS 8.1 WITH BING (Teclast beta version - no driver nedeed) - Link broken

- I used this wimboot image that automatically uses WinPE to get through the whole install process automatically without needing a single mouse click, which also has all the drivers and everything installed and working properly:

Waiting for repost on mega...

I can´t download this one because i get an .exe file of 10mb instead the zip file

Can any of you upload the second one to other server? Thks

Just an update on the USB OTG HUB.

It seems finally that it CAN charge & connect the tablet to peripherals.

The key is the order of connection:

1) Connect the peripherals to the hub

2) Connect the hub to power

3) connect the hub to the tablet.

I had tried connecting the hub to the tablet first, then connecting it with the power source; that didnt work

I was checking to buy the pricier hubs and I read the same advice about making them work, I tried and it works...

Thank god we dont need to spend like 15 euros just to charge the tablet and connect it to peripherals.

I still have the problem, that my tablet doesn't charge when it is switched on, not recognized by my PC and no data transfer possible, also no root.

I had all this before I flashed the dual boot bios and installed Android again and Windows in addition (coming from android). But I did not do the online update of Android since that gives an unknown error message.

My question: Can I re-flash under Android a single boot bios? And still boot into one of the OS, Android or Windows, so that I could flash the dual bios again, in case that I still get no ADB connection to work?

Which single boot BIOS should I take?

Your help is very welcome :)

Cheers, Steff

I am happy it worked somehow for you. Yes, i have been searching about OTG Hub & charger for long time and i read the way you did and succeed too but i couldnt remember later time :) I also bought that otg hub and waiting for it to come still..

thanks once more, it will be very helpful for others (but as i can se, nooone almost care about something like that :rolleyes: )

Applying Camera Fix and INVERTED TOUCH FIX ?

I realized that on Windows (Dual Bios) the computer doesn't recognize the device through the USB connection.

Is that common?

Thus, do I have to use the USB stick instead every time I want to transfer something?

After all attempts are made, my tablet (AIR II) still has a camera UPSIDE DOWN problem on both OSes and Windows screen is inverted as booting.

Hope we can figure out it sooner or later.

Thank you so much for all who contribute to this interesting work. :good:
[Teclast X98 Air 3G] BoORDeL:
Yes for me. Both dual or windows only BIOS.
[Teclast X98 Air 3G] kinhvanhoa:
I've used a MicroSD card to copy Inverted Touch Fix but... nothing happens.. The screen is still UPSIDE DOWN as windows starts.

For me, on Android with [MENTION=281521]jcespi2005[/MENTION]'s ROM, my device doesn't have any problem with connecting to Computer.
[Teclast X98 Air 3G] Hendrickson:
Newer Air 3G out for delivery today, hopefully it will have no flaws and a good touchscreen so it's a keeper. My Air 3G with laggy touch will be sold off on eBay if it is a good one. Touch wood, it is a good one. But now with X10HD with 64gb eMMC I shouldn't have brought it I think :(
[Teclast X98 Air 3G] steff_1964:
Recognized under Android?

Is your device under Android recognized by your PC?

Does ADB work, does it show up in the device manager? Because I cannot access mine via ADB as long as it is not in DNX mode.... (dual boot BIOS).
[Teclast X98 Air 3G] kinhvanhoa:
Another report: When I run Google Hangouts, it says "Unknown issue with Google Play Services."

He was asking for windows not for android

---------- Post added at 13:09 ---------- Previous post was at 13:07 ----------

I don't know how to solve your problem because i've got AIR 3G and not AIR II.

this coulg be the problem of your issues.
[Teclast X98 Air 3G] Hendrickson:
You need to delete or edit the touchsettings.gt in the C:/Windows/inf folder I had to mess around with mine more than others did here. I'm not sure way but it seems some touch panels are slightly different as the touchsetting.gt file included with the drivers doesn't work 100% for all Air 3G's for the Air II is different again as the up and down is inverted, but horizontal isn't.
[Teclast X98 Air 3G] kinhvanhoa:
You mean after applying the instruction (as I did already):

INVERTED TOUCH FIX (thanks to krisbliz)

You can use the DevManView to restart the "Goodix Touch HID" before the windows logon screen and everything working perfect again.

Here are the steps:

Download the file "disable enable touch driver.rar" attached to this post

So first copy the extracted files in Windows dir

Now run gpedit.msc

Computer configuration

Scripts (startup/shutdown)

Startup

Add

browse for reset driver.bat

Then, delete the file your mentioned?

Again, please find and use the link in original post, not the link in the "quote", since it is normally just a shortened "link name" that forum software recognizes as link to URL .

Requesting the key is just a sign that you use link that does not have a target.
[Teclast X98 Air 3G] Hendrickson:
I never applied that fix, but the driver and intel GFX from the drivers zip and I just deleted the TouchSettings.gt file in my inf folder. I seems for certain batches it's different. I the dual boot, I think I just edited it to 0 0 0 0 for all settings in the file itself.

Could be an isolated error, i have some on stock too, with other apps... haven't tested hangouts, usually use Skype for video conferencing instead...

I'll take a look later, but i though prefer starting to work with new base...
[Teclast X98 Air 3G] kinhvanhoa:
I tried, some other "Google Play Services" such as Google Music. It also causes an error message.

To be clear, although the error message came up, the "services" were working.

Just the error message bothers me.

Working with new base sounds really promising.

As I experienced all problems ("google services," Camera upside down and others) I wish I could understand Chinese to check out the forum on the China side. My AIR II is kind of new in the market. As many people here are using AIR 3G, I cannot figure out the hardware specific problems.

Thanks.

16:10 isn't good for me as a tablet :P

I would like to see Air II 3G - 9,7" Retina OGS, Dual-channel DDR3L 1333MHz, 64GB fast eMMC, 10k+ mAh battery, docking keyboard, magnetic smart cover... and < 250$ :D

Probably due to 3G modem - it could interfer with signals from SoC and they isolated it with metal cover :P
[Teclast X98 Air 3G] SUMMERBREEZE:
yes but we also have 3G modem in our tablet but we dont have such black thing :)
[Teclast X98 Air 3G] majkel_94:
...

Air 3G has 3G modem so the SoC need the metal cover.

Air II doesn't have so no metal cover -> big thermal tape on SoC & RAMs.
[Teclast X98 Air 3G] SUMMERBREEZE:
ahaa teraz rozumiem! :)

i was thinking to leave open the soc unit (without metal cover) for my Air 3G.. because the metal cover is just absorbing the whole heat inside and doesnt really spread the heat, maybe thats why most of us have thermal throttling problems.. but now you say it must be there cos of 3G signals? what will happen if we leave the metal case open? we will have problems with 3G?

If there will be no big problems, then we can put about 2mm thick copper heatsinks on cpu and rams :silly:
[Teclast X98 Air 3G] Hendrickson:
It's a tape with a thin copper heat spreader on it. I had a look at mine. I think without the modem it doesn't need the shield, must be due to interference from the modem.

Your right, 16:10 is only really good for movies. But its basically the same tablet but with a 64GB eMMC.

------------

Both my Air 3G C8J7 and C6J7 (Windows model) arrived today.

The Air 3G windows model is good. It's flawless, 60hz, working cameras and nice responsive touch screen. Looks a keeper! BIWN eMMC Vs the Toshiba eMMC in my C6J6, it's a little slower than the Toshiba, it must be cheaper for Teclast which is why they switched to it?
[Teclast X98 Air 3G] martyan:
so windows model is better? and really bios of windows is C6J7 ? This not C6J6 ?

And your C8J7 is android?

C718 with android but I have installed dual boot
[Teclast X98 Air 3G] Hendrickson:
Yes, I feel this Windows Air 3G is the best so far for me. And games like PES2015 like more than 32mb dedicated on the GPU and It can run at 1024 x 768 30fps in high with 512mb allocated. With the Air 3G non dual boot bios I can up this amount.

It's the C6J7. And dual boot just makes both OS's seem slower to me. The eMMC is slower it seems with all the partitions in dual boot.

All of the Air 3G's i've had don't overheat. My C6J7 maxed GPU temp is 61 degrees after 1 hour of PES 2015. My other Air 3 and Air II hit around the same figure.

I saw 1 gb as data partitation not system.. so i wanted to mean that can we reduce 1 gb data partitation to 500 mb.. but wrote as system... now it makes a bit sense? but still it doesnt give you any right to call someone like that. and what other posts you think i am stupid or troll?

I'm afraid you'll affect the windows partition, so make a backup of data first ;)

Perhaps you could redimension some of Android partitions from Windows, but you should mess up the android system, and sounds not so easy to reinstall only Android doing this...

That would be great. After I flashed the Dual Boot BIOS from Post #1929 (http://pan.baidu.com/s/1sjK4Zbn), Android and Windows, I do have dual boot and two OS, but I cannot access the tablet via ADB any longer, I can therefor not root Android, not install Paystore Fix, and not flash Android again. I also cannot find the tablet in the host PC's device manager, neither unter Android nor under Windows. And I cannot charge the tablet as long as it is NOT shut off.

Thanks for the idea. I just did that. It helped in one point: Now I can shut down the tablet under Android. It does not reboot all the time. But as sonn as I connect it with a powered USB port, it still reboots. Even after some time.

It does not reboot when I shut it down in Windows 8.1, even it is still connected with a powered USB port.

The main issue, no ADB and no charging when the tablet is switched on, is NOT affected :(

Yes, abo.adam reported exactly the same issues like I have..... no idea as well. Without ADB we cannot flash another rom.

What would happen if we choose another BIOS (e.g. a single boot one) in Android? Is it for sure that we cann still boot into any OS (at least one of them), so that another ROM could be flashed in case that does not help?

I think you can use Manufacturing Tool from PC, not need to use ADB for this... just reflash the whole Android System...

What do you think?
[Teclast X98 Air 3G] steff_1964:
I thought the same. And tried it several times. But it did only work up to 10% in MFT. Then the tablet reboots, and from then on it seems to need ADB which we don't have anymore. So nothing on the system is changed. On this point abo.adam and I had no idea how to proceed, beside flashing another BIOS in Android, which might brick the device, if we cannot boot anymore into one of the installed OS.....
