[Teclast X98 Air 3G] pbaumi:
Hi everyone, as I got no answers in the Air II thread, found no refs in this one and it's a problem which should occur on both versions:

1.) There are regular WIFI dropouts with the newest v4.

The wifi icon shows no connection for a few seconds. This occurs every 5 to 10 minutes. This is very noticeable when using tapatalk and every few pages it doesn't load the next page and when I look up, there is a short time, where wifi is not connected. When watching a video (stream via smb) there is nearly no impact. I think, it's only because of the prebuffering of mxplayer.

2.) When watching videos with mxplayer or vlc or any other player I have very clear sound and excellent speech. It doesn't matter if viper is active or not.

As the speaker aren't very loud, Iwanted to use headphones. But as soon, as I plug them in, the sound is completely messed up. Like an Equalizer is enabled with high and mid down and low up. It is nearly impossible to recognize any spoken word. I tried on, off, force on,... in viper4Android FX but it doesn't matter. My tested headphones are Philips Fidelo S2 and Xiaomi-piston-v3.

System was a clean install of mirek v4, HW: HG9n, single-boot
[Teclast X98 Air 3G] tecknight:
Yes, I am sure. The V4 ROM IS designed specifically for the Air II.

The 2 Lollipop ROMs are designed to run on all variants

I don't know what is happening... I am following the instructions you post about how to update the Bios version.

I think the adb drivers are installed (photo) and usb debugging activated and when I run the .Bat and press any key the program close and do nothing

Edit: I am running Windows 8.1 in host PC. I have tried to execute Fastboot. exe only for testing and it close too

Download the Android driver installer I have attached to this post, unzip the installer from the .zip and run it.

Let it uninstall any drivers it deems necessary and install the Intel Android drivers. When it's done, launch a CMD shell and type

adb devices + Enter

Does it see your tablet ?

[Teclast X98 Air 3G] djmvt:
Having the same problem with this device, tried solving it with the 7% method but it is not working. I am dealing with it now, at least i do get a pretty decent battery life but the tablet has to be on power every evening.

---------- Post added at 10:12 PM ---------- Previous post was at 10:07 PM ----------

Wifi dropouts i've noticed too, don't know how to solve it.

The audio problem you are describing seems to me the "apple problem": the device headphone pinout is the same as apple wich is different to the "standard" jack pinout. Try sticking the jack plug in half way, does this give you proper stereo sound? If so it is for sure the apple pinout problem...

[Teclast X98 Air 3G] pbaumi:
WOW You are completely right. When messing with the jack, I get different channels and one of them has a good vocal quality. But this just points out the problem. Do I need an adapter? Isn't this standard 3.5mm jack? I only tried headsets - I'll search for something without microphone.

[Teclast X98 Air 3G] tecknight:
you are doing great, but you need to run the first command from the folder where you extracted the flasher archive

there should be a folder named X98-Air-3G-andriod-and-win8-bios in the flasher folder

you are running the command from c:\users\Jesus

We need to run the command from the same folder where FLASH.BAT is located

We are VERY CLOSE to flashing your BIOS

This command:

adb push X98-Air-3G-andriod-and-win8-bios /data/local/tmp/

looks for a folder named: X98-Air-3G-andriod-and-win8-bios and pushes the entire folder and it's contents to your temp folder

This post answered a number of questions. First, I was having trouble finding links to mirek190's V3 lollipop ROM and I wasn't sure it would apply to my AirII after seeing mostly specific versions of V3 for variants of the 3G. Thank you!

Also, I was pleased to find your sig included a link to fixes for boot to windows including one specifically for the AirII. I applied that to my current Mirek V4 KitKat ROM on BIOS 2.02 and it works perfectly! How does boot to Android from Windows work?

EDIT: Oh, I found this earlier post by you with the windows app... That should work, right?

You had to unzip the .zip file to a folder somewhere or if you don't know, just unzip it again to somewhere you know

It looks like the archive itself is in your downloads folder, so browse to the downloads folder, find the .zip file, then right click on it and select Extract or something similar, then tell it where to extract the data to
[Teclast X98 Air 3G] sahor:
There is something that I should know I think. I have tried to put the folder in some places in my PC but I understand you that I have to change the "data/local/temp" for the place where my folder is (for example C/, but I am a bit frustrated because I am trying to understand you but I can't.

For example I have just unzip the folder in my desktop but I don't know what I should write.

Yes you are correct !!

Also if you click on the TTT in my sig you will see my current tutorials.

I just completed the Install Intel Manufacturing Flash Tool and I am now working on the Flash an android ROM without affecting the existing Windows install

I personally like V3 Lollipop best of all. The UI is way smoother than Kit Kat and it is nearly 10% faster in Antutu. It has a couple of small cosmetic bugs, but they are insignificant, IMO.

OK if you unzipped it to your desktop then do this:

1. Browse into the folder you created on your desktop when you unzipped it

You should see a FLASH.BAT file with a gear on it.

Once you are in the folder with the FLASH.BAT, then find a blank area, hold down the SHIFT key and Right Click.

Select "Open Command Window Here"

and it will open the command prompt we need

I was successful in updating my Air II 64GB Dual Boot (HG9M) with the 2.02 Bios file using the above instructions.

My heart was pounding as I did it and I left it for a minute or so after flashing, it also took ages to turn back on after the flash so I assumed I had bricked it, thankfully it booted up and I have been able to switch between Android and Windows from the opposite operating system fine since.

My Windows stayed activated, is that normal? I had saved my key anyway but I thought the Bios wiped the key, or will I need it when I format? Did I need to use the chinese software to inject the key back into the Bios?
[Teclast X98 Air 3G] siezed:
Replacing the bios just deletes the key from being saved in the bios, its still saved in windows and only would matter if you tried to restore or reinstall windows, then instead of windows seeing it in the bios you'd have to type it in.

---------- Post added 14th July 2015 at 12:04 AM ---------- Previous post was 13th July 2015 at 11:54 PM ----------

in his defense, there was a few times your sig didnt show up for me, no idea why or how it got fixed, or if he even had the same prob though.
[Teclast X98 Air 3G] Mattycee:
Thanks for that I thought that may have been the case. I used the software to back up my key in the bios so I can re-inject it I guess. Not sure I am too fussed anyway, as long as I have the key (Which I do) I am right to activate Windows anyway.
[Teclast X98 Air 3G] siezed:
yea i didnt bother, i might when i get my win 10 key but for the 8.1 i just took ampic on my phone and thats good enough for me, i should probably write it down if i was smart, but im not so...
[Teclast X98 Air 3G] tecknight:
Yes it is normal to stay activated as the software key is stored in the Windows registry.

The software key in the BIOS is simply for convenience as it will automagically populate if you reinstall Windows 8.1. However it is no different than typing in the software key and my Windows 8.1 key won't be in use after July 29th, when I claim my free copy of Windows 10 with its own unique software key.

Yes I really like the boot to other OS option, It actually works better and faster than a normal reboot--It never stops whether I am charging it or not

I wanted to test the Teclast Android 5 beta Rom to see if it helps with the battery drain I am having but it will not install. I can install Mirek's rom no issue but when I try and install the rom from the official source it fails at 22%. It also logs into a different screen on the Tablet if it is going to work.

When the rom successfully flashes it goes to a dark screen with light blue writing and when it is going to fail it goes to a Fastboot screen with the little Android man on it. I am not sure how to install it to test, any pointers?

[MENTION=2198172]mirek190[/MENTION] i just flashed your 4.4.4 v4 to my air2 hg9m 64g dual boot and it seems hearthstone is actually working smoothly!! Thank you very much but im curious why it works on your 4.4.4 rom and is choppy as hell on any other rom, even the v3 lollipop, cause it'd be really great to have hearthstone and 3d games in general be working as they should in 5.0 v4 =)

- changed governor and upgraded ( stock governors works bad .... )

- a ton of optimizations for cpu

Yesterday I got a package from Anna Feng.

I took the Air 3G dual OS with 64 GB but the model is C5J6, does it mean I got older model? I do not think that it was used, everything was nicely packed.

Does anyone make changes in an older model, I would not make bricks after a week.

Will the new system also has so many Chinese letters?
[Teclast X98 Air 3G] djmvt:
C5J6 is the latest model, you've got the right one ;)

Well, that is not the problem in my case (air II hg5n loaded with teclast bing windows) - left the tablet at 100% in the evening, now it has 99% of battery. however I disabled realtek device to wake the tablet I device management. Maybe this is the answer to battery drain, also you guys have 3g and GPS, maybe you should disable those too when you don't use it.
[Teclast X98 Air 3G] keepfishes:
Thanks for your suggestion.

I have tried everything from muting the audio before sleep, disable the device driver for Realtek I2S and Intel SST and they all still cause battery drain.

I even tried uninstalling driver for Realtek I2S and Intel SST and it still does not work. Reinstalling driver also doesn't work. However, in the Sleepstudy I see that it is SB.LPEA device that is running at 100% activity and preventing the system into going to sleep. SB.LPEA corresponds to the driver BIOS name of the Intel SST Audio Device, so I suspect that this is the problem. But I have tried multiple methods to get rid of it but it still doesn't work.

I have to say the Lite ROM from the Teclast forums is really good on battery so far.

It dropped from 100% when I took it off charge this morning to 96% 10hours later when I got home from work tonight.

So I do think there is a programming problem or a process in the official Teclast android releases that drains the battery even with gps, wifi, 3g etc turned off.
