hello man, the second video is very promising.. its great to know the tablet as like a desktop pc as long as you have a monitor(with hdmi) , keyboard and mouse :D (we can use wifi mouse-keyboard set yes? )
[Teclast X98 Air 3G] Hendrickson:
Yes it runs well as long as you don't expect it to be lighting fast it is an Atom 2W soc. Chrome can lag a bit, as long as you take it easy on the ram and multi-tasking it's fine. The bottleneck as always on these new bay trial tablets is the eMMC drive.

I've been using it in desktop mode a lot recently as I like the fact its dead silent, my Surface 3 Pro was loud and the fan would come on often. My desktop has like 6 fans in it so it's loud.
[Teclast X98 Air 3G] HDtracer:
That is high.

I dont find Android to be particularly good either, at around 1-1.5% per hour in standby with wifi off.

It can lose more than 10% in 8hours over night.

Compared to my LG G2 which might lose 2-3% at its worst and wifi is never off on my phone.

I cannot find what is causing the drain and suspect it is something badly coded in the firmware.

Even using better battery stats and wakelock detectors I cannot work out what the problem is.

Battery use always says that Android OS is responsible for 75% of battery use. My LG is around 6%.

[Teclast X98 Air 3G] Dudeonyx:
Damn if I'd known I would have ordered that instead of a 32 GB, oh well

I just realised from reading the last few posts that the current c6j6 windows bios is prolly incompatible with the new c8j7 android air 3g.

Thats bad news for me as i just ordered an air 3G android 3 days ago so it might be c8j7, and I'd originally planned to install win8 asap.

In the first place is there any hardware/software/firmware difference btw the c6j6 & the c8j7, though it's probably to early to tell

So maybe the guy(?) with a c8j7 could dumb his bios and someone knowledgeable could check if its diff from c6j6 (a word? I've repeated too many times in a single post despite having zero idea of its meaning )

Why teclast won't make the dual boot for the old x98 Air 3G.

[Teclast X98 Air 3G] robusto:
I would imagine that there is a reason why every other batch c6j6 etc has the windows bios at teclast web page but c8j7 does not... Didnt want to experiment with flashing and risking having a beautiful paperweight just after a couple of hours of testing, so decided to play the wait game and see if theres a windows bios coming days to come.. I can understand your frustration because I had the very same plans of quickly flashing win8, even bought an active usb hub for this. Lets wait and hope for the best..

Yeah it's a real problem for me because most of the time I put the tablet to sleep to save power, and it ends up killing my battery and I can't turn it on... What I do now is keep having to shut off the tablet when not in use for some time.

It's funny that only two of us are complaining about this, maybe the others don't encounter this issue.

Wi-Fi issue with Mirek's v4

I have a wifi problem since installing Mirek's rom v4 android 4.4.4:

My C5J6 (bios 2.02) connects and stays connected to my home wlan but google apps (gmail, play store etc.), standard browser and some other apps like news feed reader loose connection to their servers after few minutes. Typically the only way to restore their access to internet is to switch wifi OFF and then ON again but that helps only for 2-10 minutes. The weird thing is that Firefox almost always stays connected to internet when these other apps have lost connection.

With the original ROM and both with 1.07 and 2.02 bios I didn't have this problem. When installing v4 I did the full system wipe.

I don't have many apks installed, no games and no battery helpers. I disabled AdAway but that didn't help.

What could be the issue here? And how to solve it?

Thanks already in advance.

Installing ROM on a dual boot device

Hi guys, this is my first post here - I tried looking for the answer on this thread and couldn't find it, sorry if it's been asked before..

I have the C8J6 (Air II 3G) and currently running dual boot Win/Android. I'm trying to figure out how to install mirek's ROM and maintain the dual boot setup, without losing anything on my Win partition.

Is there another way to see the bios version? I don't have here a USB keyboard and I can not checked.

I am interested in flashing the android part (HG9M dual boot 64gb) and I think that las mirek rom (kitkat) it could be the option(or one what you recommend more stable,I don't mind to have Lollipop) I have downloaded the files but I don't know what should I choose and I can't see instructions.

There are too much files with an explanation (NO DATA FORMAT, NO WIPE DATA, and the partition tablets...)

I would like to keep the windows part, and flash android, because there are too much Chinese apps that I don't know if I can uninstall(I have read that one of them is important for Teclast updates but I don't know what it is.

Hi. I had my X98 Air II HG9M for arroud 2 months now, and yesterday I updated the bios to 2.02 correctly. I flashed a custom android rom from mireks or something like that for the Air II and everything went well. Today I went ahead and wanted to install windows 10 on it, so i went to the bios, loaded defaults and overrided the boot to the kingston usb flash drive. it restarted and the windows 10 installer failed because it was 64bits while the tablet is 32 bits. it shutted down and now it won't power. i tried disconnecting the battery leads one at a time (gnd, then soldered gnd in, then unsoldered bat+ then soldered it in again) and it won't solve it. what do i need to do now?
[Teclast X98 Air 3G] sahor:
I can not see the instructions in post 2...I am not an experimented user, I am only a simple follow - tutorials...could any one tell me step by step instructions... Thank you so much. (I am not root, and I haven't updated the bios because I don't know what I have.) I have read that tecknight was going to show new methods to see the bios version... And a full collection of high quality tutorials...

[Teclast X98 Air 3G] mrunderhill:
Thanks for your help. Before I start the procedure I have another question - the guide says to do the following:

I've recently upgraded to the 2.0.2 BIOS - do I still need to do this? The BIOS they're referring to is older...
[Teclast X98 Air 3G] mrunderhill:
MANY thanks! I assumed that, but would rather make sure I don't brick my tablet.

One more question remains - how do I find out the right VID and PID numbers for my tablet?
[Teclast X98 Air 3G] siezed:
ok for that you wanna follow the tutorial and install the adb drivers (they allow your host pc to see your tablet) plug the tablet into comp while in fastboot (in tutorial) then from host (desktop windows pc) right click the bottom left corner, click device manager, find adb android device, right click, properties, details, hardware ids. then you switch to driodboot to get the android ones, its all in tutorial and actually i skipped the android hardware ids, its my understanding theyre just so the intel mfg tool can see the tablet, so if it actually sees and flashes youre good these arent that important unless the tools not seeing the tablet.
[Teclast X98 Air 3G] sahor:
OK, thank you very much... I will read slowly at home....It was very very difficult to understand to me without your purple help...

I understand that I don't need to root the device before and neither to update the bios (only if I want to use the switch button to change OS directly) , It is right?

And about mirek rom...

Is better to flash Lollipop? What version (v3,v3.1 C8J7, v3.1 C9J7) should I use for HG9M? In V4 there is a file for Air II that I can't see in v3 versions, But I suppose that you recommend v3 because is better...

Once I will chose a rom version, I will flash the file from mirek rom you tell me, but what about,what file should I use from the followings?

Too much doubts, thank you for your patience.

[Teclast X98 Air 3G] mirek190:
Ok

V3.1 , V4 - newest - android 4.4.4 ( most stable )

V3- early beta - a bit older - android 5.0 ( beta - Propably camera doesn't work , memory leak )

It depend how you want flash .

Via MFT or via that bat files on your screen.

From android with wiping data or from droidboot ł.

If you run one of that files then you get directions what to do .
[Teclast X98 Air 3G] siezed:
I believe you have the wrong file, or at least a different one that i used, download the one that says "all variants" should only be 3 flashable files, lemme know if u cant find ill go and look
[Teclast X98 Air 3G] blade_:
hello,sorry for asking,but this is a flashable rom?i have to find a suitable recovery first?thank you
[Teclast X98 Air 3G] siezed:
I only recommended lollipop v3 "all variants" because its the file i used, with those instructions, and its working pretty well. The camera is wonky, like it doesn't focus right and makes a clicking sound when you switch from front to back or open camera app, if you really need camera go with the 4.4.4 version, however i havnt used those files and someone else may need to help you, but the procedure should be the same as long as you use the dual boot file that keeps windows the way it is. Basically mireks done most of the work in keeping the system how you want it in the different files, its just a matter of flashing the right one, Heres a link to techtablets with all the roms; http://techtablets.com/teclast-x98-air-3g/downloads/ if you decide on 4.4.4 use air ii(or whatever model you have if someone else is reading this)if you decide on lollipop use the X98 Air 3G (All Variants) Android 5.0 Beta V3.0 Mirek190 (336.4 MiB) .note theres a memory fix that involves installing xposed and getting the memory fix "app" through the exposed framework, if you decide to do it. I did it without issues.

X98 Air 3G multirom

Hi, guys. Sorry if I'm doing anything wrong, this is my first post here.

I was wondering if we can install multirom access on Android. I've been searching and found nothing. My idea is to have dual boot with Android and Windows and multirom within Android. For me the perfect system would be Windows/Lollipop+Remix OS.

Is it possible? Am I asking too much? Any help is appreciated. =)

Hello Dear,

Have you installed the mirek's ROM yet? If not, you will need to replace the boot file with a different one while flashing the included BOOT.IMG will not work on C8J6 models. The only issue is that the touchscreen does not works in the android mode. Use this for the time being.

Feedback on Mirek190's 4.4 v4 ROM for C8Jx

Currently the ROM is excellent, everything is smooth, perhaps the smoothest so far. It'll be hard for me to go to Android 5.0 at all if it can't match this kind of performance.

There are a few bugs that I've seen so far.

1. Front camera is still inverted

2. The mute icon is not scaled properly in the tastebar.

you should find your stock firmware at this link:

eg the c5j6 is on page 3 or 4

download the android and win8.1 files and store them someplace safe. you find howto apply them on the first page of this thread. i found the hendrickson video quite helpful.

ps. loaderdroid is a good app to download with. i had trouble staying connected for the big files and loaderdroid is great at resuming a download.

good luck
[Teclast X98 Air 3G] tecknight:
It's a very complex problem. Apparently the touchscreen normally works ok at first and at some point it becomes special.

Once it becomes special, it rarely reverts back to working normally. Teclast probably knows what the real problem is, as they released a special boot.img for the issue which almost always fixes it when running on android 4.x but it doesn't work on Lollipop.

Mirek and I have spent quite a bit of time examining the boot.img contents to see how it differs from the standard image and while we have found some obvious differences, making special touchscreen models work under lollipop has been a challenge.
[Teclast X98 Air 3G] mirek190:
Which version the tablet you have ?
[Teclast X98 Air 3G] tecknight:
I'm sorry to hear that this happened, you actually did everything right, except for the 64 bit Windows. By the way, the X98 does have a 64 bit processor, but the BIOS are 32 bit only. It certainly sounds like the BIOS got wiped somehow by the attempted Windows install.

The only suggestion I can think of that hasn't already been mentioned is to try powering it up while connected to a Windows host PC and watch device manager on the PC to see if any devices show when you connect the cable. If any do, you might be able to do something. Honestly, though I think it's probably going to require an external BIOS flash to fix. Many have reported success in recovering tablets using this unit:

No, unfortunately it's the BIOS that determines which OS to boot and support for automated selective OS boot was only added in BIOS 2.02.

The only way to make it work is to update the BIOS.
