Hey,

figured out on Friday, that I wasnt using correct PID/VID. I entered wrong PID/VID for droidboot.

That solved my situation.

thanks for the help !
[Teclast X98 Air 3G] benbraun322:
So mine just arrived and it's a C8J7.

How are those in general?

Good news?

Bad News?

I'm planning on installing Dual Boot on it (it is only Android right now), with 4 Gb to android (or less if possible) and the rest for Windows.

Which ROM and partition file should I use for it so android will have the lowest amount I can give it while still working for Dual boot.

And how can I check before flashing and installing and everything that mine doesn't have the 3D error because I'm planning on playing some games on it eventually.

Thanks in advance

If you read all tutorials or maybe use search threads you will have answers....

Why ask again and again same thing?

Just read dude.... And if really need help then we are here...
[Teclast X98 Air 3G] benbraun322:
Okay I'll rephrase it all.

I know a lot about this and have read much of this forum multiple times.

I'm planning on following Hendrickson's video which I've already watched a couple of times.

He showed in his video the different partition files included in the ROM, but I honestly just didn't understand the partition part I wasn't sure if the higher numbers meant more for Windows or more for Android and vice versa.

I saw a few times that in order to test the tablet for the 3D kernel error you should play a few games of Asphalt 8, but I was not sure if that was for Android or only Windows, would playing Asphalt 8 on android trigger the 3D error?

Oh and can I plug a external Hard Drive into the tablet via the OTG port?

Thank You

Ok, today i tested Air II bios (windows only), and in 8:30 hours battery drain was of only 3%, in total.

So it is clear, this bios and original C6J7 are the only bios without battery drain.

About Air II bios, i can confirm too that GPS is not working, i tried different configurations, adding legacy hw and different hw names, but GPS is not working. So, using Air II bios we lost GPS function.

About brightness, i can say that i can't see a lot of difference between Air II bios (60Hz) and c6j7 (48Hz) bios. Maybe the great difference is between single and dual bios. I ask to [MENTION=1167021]Hendrickson[/MENTION] for his opinion in this case.

So, guys, the only bios that is full working for windows in our tablet is original C6J7 bios.

I would ask to more experienced users like [MENTION=1167021]Hendrickson[/MENTION], [MENTION=2198172]mirek190[/MENTION] and others (sorry for not write all nicks) if we can try to dump again C6J7 bios and try to get it working.

First of all, for letting people having original C6J7 bios dump their bios, i would ask you

how to dump the bios using windows

.

Waiting for you inputs, Thanks!

I don't mean to be rude, but if you already read the forum, and seen the video, there's not much more we can do.

Just follow the guide, the instructions are very clear, everything will be fine. Unless there's a problem, in that case, we are here to help.

PS: Asphalt 8 for Android, if there's the GPU problem, the tablet will freeze after a couple of minutes while playing it.
[Teclast X98 Air 3G] benbraun322:
Thank you for your help.

I want to make sure that my tablet doesn't have the 3D error before I install dual boot so if I have to return they can't pull the whole "you messed either the tablet, it's your fault not ours" bit.

[Teclast X98 Air 3G] BrocasHelm:
The unity benchmark works as well. And you don't have to run it many times, just once at 1080p and leave it there for 5 minutes after the end of the test. If it's frozen you have the problem, if not you are lucky.
[Teclast X98 Air 3G] antony84:
3D freeze

About 3D freeze.

I played Asphalt 8 in windows, and the game after third race had some micro freeze/lag (about 1 second) but never frozen. it was very hot. But i can play the game until the end.

So, my question: what we mean for 3D game problem: the tablet should frozen and we need to restart it by power button or even some freeze/lag are due to gpu bug too?

boot menu language

Hello,

Is it possible to change the language in the os select screen?

& another quick question. Where can I find an english guide on how to use the microvirt application (my tablet came with this app (Teclast x89) and based on the videos on microvirt site it is very cool (you have win 8 and android running in the same time))?

Thank you!
[Teclast X98 Air 3G] xusso:
Please try also the unity benchmark utility that was mentioned by BrocasHelm.

I just got a X98 3g 64gb C9J6 a few days ago its a great tablet after a few minor issues are resolved.

so far I rooted installed xposed and flashed the mirek190 C9J7 system.img android is running and tweaked just the way I like it until we get Lollipop. I ran unity benchmark for over 20mins no issues and played asphalt 8 on android and windows with no issues. Guess I got lucky and received a good one. The only issues I have is battery drain in windows Android only lost 1% battery in 3.5 hours with screen off today. Windows looses around 2-4% a hour. My volume in Android is not as loud as in windows none of the tweaks seemed to make any difference.
[Teclast X98 Air 3G] liu-zhen:
My C9J6 also has no GPU issues. Maybe they have fixed it?

I do however have quite bad battery drain (3-4% per hour) on Android and Windows. Both are stock though so might explain it.

Holding off for Lollipop to update/flash anything.
[Teclast X98 Air 3G] StefMug:
Nice long thead in here... my first post, two questions... :angel:

I have already bought die Teclast Air 3G (with dual boot), it's nice and the UI ist pretty smooth, so I'm glad for now and would like to stay on stock rom.

But there are two negative things i've detected:

1) battery drain is pretty heavy (on Android it lasts only 3-4 days in deep standby), so my question:

- How long das your Teclast stay in android standby?

- How long in windows standby?

2) WLAN receives excellent signal, but frequently it does not connect due to "authentification problems":

- are there new driver for Android?

- Howto install?

My tablet is latest version (C9J8)!

I thougt there are already the latest driver installed and there should be no bluetooth/wlan problems...

greetings from austria,

Doesn't look like it's included in the Teclast package.

Maybe it's not even compatible with our tablet.

[Teclast X98 Air 3G] iPWNtehNOOB:
Bumping this :)
[Teclast X98 Air 3G] rudnik8:
1)

On android my teclast drains about 0.3-0.5% per hour in standby mode. After 3 days of doing nothing i had about 75% of battery left. Maybe try greenify and some battery monitor and watch your wakelocks

On windows there is this stupid connected standby bug, and it drains about 3-5% per hour

On screen i got 8,5hour max(just testing with stopwatch and lighted screen, nothing more) and about 5,5-6hours of normal usage

2)WLAN is another bug, sometimes it disconnects and will not connect automaticaly, unless i'll light on the screen. Dunno how to fix it

Hi guys, sorry to bother you about this but I'm trying to re-install android and windows 8.1 in my teclast x98 air 3g (model C9J8), want to give more Gb to windows partition. Android installs with no problems (mirek's rom for C9J7) and everything on android seems ok. But when I'm going to install windows, cannot boot from the USB stick: my teclast x98 3g already has "from factory" the dual boot bios so no need to install another one right? the boot screen to select operating system is, but only shows android, ok, I entered the bios, changed boot order, burned with rufus the windows 8.1 iso (fat32), tried MBR/UEFI and GPT/UEFI both, and my tablet is not booting from USB stick, tried with several usb sticks (8, 16, 32 gb) and burn the windows iso with several programs too (rufus, ISO2DISC, with commands in cmd window) no results. Always shows the select OS screen with android, I have 2 HUBs... not working... Tried booting just with power button, pressing vol + and power... no results, always the same screen.

If I get a Android OS version of Teclast X98 3G Air II, is it possible to install/flash Windows 8.1 instead? Or even get dual boot?

Yes.

Although this isn't the Air II forum. You either have the X98 Air II or the X98 Air 3G.

Make sure you know what you are purchasing and always try to use the Forum's search function: it works

GPS with Windows 8.1?

Hello,

This is a geat forum, thank you everybody! I am desperately waiting for the X98 Air 3G with 64GB ROM shipping from EU. Unfortunately this tablet is not available here yet.

After reading through the forum there is one question I have not been able to get an answer to. I would like to know if it is possible to use the GPS in Windows mode (eg. with the Software CompeGPS Land). Is anyone able to confirm GPS is working with Windows, too?

Thank you.

[Teclast X98 Air 3G] ZIPmagic:
I'm sorry the site sees spammy, please feel free to provide suggestions to increase credibility. :confused:

The tool works perfectly and it takes just a single-click to get the job done. Yes, for real - if you have any doubts, fire up a Virtual Machine first, and test to your heart's content first! :highfive:

I recently added the following upgrades to ZIPmagic and DoubleSpace, just so you know I am fully behind my product, and constantly working to improve the user experience across the board, in all possible customer scenarios:

On the DoubleSpace front:

1) Built-in support for pre-WIMBoot’ed systems. DoubleSpace now undertakes the following actions on such systems, typically 16 GB eMMC hardware:

a. It automatically deletes the newly redundant WIM from the separate WIM partition.

b. It relocates the Windows Recovery environment from the separate WIM partition to the main partition.

c. It deregisters the old Windows Recovery environment, and re-registers the new one. This ensures Windows Recovery tools continue to work normally.

d. It deletes the partition hosting the redundant WIM file.

e. It extends the main partition to cover all space gained from the redundant WIM file.

Frankly, without these options, it would have taken quite a bit of manual work to realize space savings through DoubleSpace on pre-WIMBoot systems. The user could still manually delete the redundant WIM partition and extend the main OS partition; but this would not have kept the Windows Recovery environment without additional finagling on the command line.

2) Built-in Check Disk. DoubleSpace now checks a disk for errors before beginning the operation. I trust this new feature will also help a lot of people save data that might have otherwise been corrupted.

On the file compression front:

3) I did some more customary enhancements to improve the performance and reliability of the shell namespace extension. This is an extremely complex area (have you wondered why 7-Zip, WinRAR, WinZip have never even tried to implement this?) and it takes constant fine-tuning to keep perfect.

4) New 64-bit compression is now available. It outperforms every other algorithm known to me if your computer has at least 12 GB physical RAM, and you select the Super Strong compression feature in the setup wizard.

5) Parallel extraction of archives on SSD hardware. For example, if you select 5 archives in Explorer, right-click, and choose “Extract”; five processes will simultaneously extract the data. On an SSD, there is no reason to perform the extractions in serial – unlike all the other archivers out there.

ZIPmagic is a true hidden gem...and we are looking for more feedback and support from the community. Thank you!

Charging Clarification..

As mentioned few posts before i recieved my Teclast X98 Air 3G C9J8 with 32gb from Aliexpress last week. i really like the way it does and now i got a question about the charging. There is no charging indication on screen all the time or? Only when its completly off and i press the power button once it shows me a charging indicator. Then i tried to charge the tablet in windows and android but it only does it in android. is there a way to charge it when i am in windows?

best regards,

EDIT: I used a charger from work now and not the ones i got at home and it shows the charging now. but BatteryBar stays at 92%; loading rate 0mW and the windows battery indicator says it loads and also stays at 92%.

But all of a sudden the broadband drivers cannot load anymore (CDC MBIM) after few reboot that took longer than before i try to load them and tried to reinstall the drivers and now the device isnt shown anymore anywhere :( not in the device manager (not even under hidden devices). i also checked the bios to see if its somehow disabled there but there is no option for the 3g card. is there a way to restore the 3g functionality? should i try to update the bios? its on 1.03 or should i try to set win8.1 completly back to start? or can the connection get loose on the mainboard?

Well it worked for me as it reboots the tablet into a custom Windows PE environment I think which gives doublespace exclusive access then reboots again when its done its work

I bough zipmagic a few weeks ago after getting my own Air 3G

[Teclast X98 Air 3G] ZIPmagic:
That's exactly right on all counts :) DoubleSpace needs exclusive access to your boot volume.

Typically you would WIMBoot a PC by booting it off of an external Windows PE thumb drive, manually run tons of commands, etc. And that is after downloading 3+ GB of data from Microsoft, so you can create your own Windows PE image. A lot of work, and needs a lot of space.

DoubleSpace is contained in the very small ZIPmagic download (less than 20 MB) and it adds a new boot menu entry to your PC, which you just tap on when rebooting, and bingo! You're in the exclusive processing mode, where you can do everything safely and quickly, without needing to download tons of data, find an external USB, or execute countless command line scripts to create Windows PE or WIMBoot. It's really super convenient, because its meant to be.

Who says Mac users are the only ones who get to enjoy one-click, well-designed, braindead-simple tools? :D Now there's ZIPmagic and DoubleSpace.

---------- Post added at 10:13 PM ---------- Previous post was at 10:08 PM ----------

Yes it does :) You get to enjoy the one-click convenience of DoubleSpace without paying anything; you are even free to uninstall ZIPmagic after the process and keep your compression savings if you like.

The only thing you lose is the higher compression settings. If you're strapped for cash, you can always purchase my product, and if you don't believe it has been worth your investment, you can always get a fully unconditional refund within the first 30 days.

We do not ask questions, we unconditionally approve all refund requests, as long as they come in the first 30 days.
[Teclast X98 Air 3G] kosrica:
I believe the explanation for the 3d games freezing issue is how the default values for the min and max frequencies of the gpu are set or better said not set. As you can see from the screenshot by default the min and max values of gpu are set to 646mhz which in fact is the maximum frequency which is supported by the gpu according to the intel website: http://ark.intel.com/m/products/82...Cache-up-to-2_16-GHz#@product/specifications

After I have set the min value to a lower frequency like 313mhz (the gpu base frequency according to intel specifications) I have no problem playing any games.

Therefore the problem is that teclast set the gpu to always run at the maximum speed available so the gpu governor could not function properly.
