Don't need to update BIOS.

There are 2 XML files:

1. Flashes ROM and wipes data. This is the recommended method.

2. Flashes ROM and leaves user data intact. I don't recommend this method, but of course, that is how I imaged mine and mine ended up working perfectly.

Neither method does any partitioning, so any Windows partitions will be unaffected
[Teclast X98 Air 3G] mikbe:
That's strange. Your img's are the only ones I can't view with EXT4 Unpacker. It always displays an error in a language I don't recognize.
[Teclast X98 Air 3G] mirek190:
I know that problem - if you want "normal " sound on headphones - just swith off viper4android then will be OK .
[Teclast X98 Air 3G] articsilverfox:
Yeah I had that problem, I was digging around settings etc in viper4android and I ended up just checking 'Compatiblity mode' and then rebooting the Teclast and the sound problem went away.

But its probably %50 chance that just rebooting the tablet made the difference over changing any settings in viper4android.

Theres always a creeping looser feeling I have with little issues like that when I start changing around settings when my deeper long term part of my brain is saying 'just reboot it you moron and I bet it will go away!'. And I can't argue with that part of my brain, unless I have xray vision and can see the electrons inside the RAM and CPU how could I argue otherwise?

Hi,

I'm trying to flash my bios Teclast Air II HG9M from 1.08 to 2.02 following all instructions.

My Air II is in Android with usb debug on, I'm running the Flash.bat from my Win 10 laptop connected to my Air II by USB.

If I run the flash.bat I'm stuck at: waiting for device , deamon started, List of devices attached.....

Any ideas? Do I need to run it as administrator?

Thx,

Running it as administrator:

waiting for device...

I know it's only cosmetics but has anyone translated the dualboot bios to english? I would love to see an english enter button.

Teclast Malaysia is selling the tablets with english dualboot bios but they don't offer a download for it :(

Also I had some problems with the mobile broadband driver: sometimes the driver gets messed up and this results in total loss of mobile internet. Even the mobile broadband device gets unrecognised in device manager.

This is on windows 10.

I am testing now with disabled selective suspend in device manager to see if it is more stable then.

I upgrated my x98 air 3G c6j6 first. But menu and so on dont work. So reinstall by usb stick.

Now works everything well. Only my front and rear camera is inverted. Is there a fix for that ? Or can I use the Inverted Cam fix from first page ?

Do I need the Bios 2.02 or can I install Mirek lollipop without it ? Can I install it directly from my Mirek ROM 3.0 for C6J6 ?

thanks...

Awesome tecknight! Does teclast Ota work with this?
[Teclast X98 Air 3G] juanmaasecas:
The issue is on c6j6 and in some other model I think... The newer models mount an omnivision front camera and the bios is for that camera. Older models such as c6j6 mount a GC sensor camera and doesn't work in Windows because of the 2.02 bios is programmed to the Omnivision camera...

In older bios, those with the OV front camera used same OV driver, while c6j6 and others could use GC driver and camera worked fine, but no more after bios update...

If only teclast developed a new bios compatible with every version of teclast x98 air...

Hi guys,

I have the HG6N model and in Windows (8.1 / 10), the front camera is not working; I am assuming it is exactly the issue you are discribing. No camera works on Mirek's v3 beta ROM either.

Based on what you said... Should I understand that I need to "rollback" my BIOS to an earlier Air II version for the Camera to work, or is it something that can be fixed in Windows / Android?

-- EDIT --

Also, when I select "Boot to Windows" from Android, it won't detect my SD Card. I have to shutdown first, THEN boot to Windows, for it to be detected... Anyone has seen this?

Thanks,

Michel
[Teclast X98 Air 3G] juanmaasecas:
Both Cameras work fine in other roms in Android, the issue in Android is only on mireks lollipop v3 beta. Try mireks 4.2. The real problem is only on Windows and 2.02bios. You can search one of my post here where I describe how to downgrade your bios to 1.03 dual bios with both cameras working.

I've not realized what you say about the sd card, I'll check it when I have the time.

I wanted to try your 3G Android 5 ROM on my 32GB Air II. I'm currently on mirek's kitkat v4.2 with Win 10 and BIOS 2.01. Everything has been working fine except the front camera in Windows, of course.

Flash fails with the following log. Is it because mirek's ROM defaults to a 1GB system partition? If so, how can I return to a 1.5GB system partition? Steps aren't outlined with mirek's ROM as far as I can see. I reflashed V4.2 for the time being.

Nobody speaks chinese here? It would be wonderful if somebody read teclast forums and could eventually discover if they've fixed the front camera issue in some models with latest bios...
[Teclast X98 Air 3G] tecknight:
cosmo,

I am sorry to be the one to tell you, but you have bricked your tablet.

This means the only way to fix it is to get a USB BIOS flasher and reflash the BIOS using an external flasher.

There is a reason that the flasher script and the tutorial instructions display:

IMPORTANT: Hold the power button until your tablet powers off.

I can see from your FLASH log that the flash was successful.

We have noted that when the system is powered off by hardware immediately following the flash, the chance of a brick result is almost zero.

My theory is that the flash process leaves the BIOS in a vulnerable read-write state and if a BIOS call is executed in this state, it is likely to corrupt the BIOS image.

At this point, you will need to obtain a CH341A BIOS flasher like this one:

http://www.ebay.com/itm/24-25-Serie...H341A-Module-W-Software-Driver-/161436716985?

and a test clip like this:

http://www.ebay.com/itm/SOIC8-SOP8-...-Programmer-/141377097279?hash=item20eabb4e3f

You will then need to open up your tablet and flash the BIOS from a PC.

There are instructions in this thread, just search for them.

Good luck my friend. Sorry to have to tell you this.

---------- Post added at 04:07 PM ---------- Previous post was at 04:02 PM ----------

I agree 100%. It's pretty likely, since all the Teclast developers probably check out the forums as well.

Reinstalling Windows 8.1 (OEM)

Hi, I'm struggling to revert to Windows 8.1 having had Win 10 preview running for a few weeks. I did make an image of my Windows system before trying 10 but it fails (a strange split SWM issue.)

After trying an English language version of Win81 with Bing - and it being rejected with my activation key - I need to put the "proper" Teclast version on.

However looking at the instructions on page 1 and examining the scripts I'm aware running that WinPE install will remove the Android partitions. I don't wanna do that!

Elsewhere in this mega-thread there appears to be a way to put the OEM version of Windows on without repartitioning the device but (without installing it) it appears to be Win 8.1 Pro, which I don't have a key for.

The other alternative is to find a way to make the 8.1 WIM image install from a USB stick but that's eluded me.

Has anyone done a reinstall of the OEM version of Windows 8.1 with Bing like this please?
[Teclast X98 Air 3G] tecknight:
Bus Pirate looks nice, but it won't flash an EEPROM chip.

The file you need to flash is X98_Air_3G_Dual.bin from the FLASH202 archive.

It is remotely possible disconnecting battery might work. Can't hurt to try.

The only way to flash the BIOS image is to get a flasher like the one I posted the URL for.
[Teclast X98 Air 3G] massivekind:
Well I did install a Chinese bing edition with modifying the winpart file ( or something what ends on "part") but I wouldn't recommend that for installing Bing. At the end I found a Bing image ( in English) and used rufes to create a bootable USB drive. If you get an error when you select the partition ( while trying to install windows on a partition, select MBR in rufes and create a new bootable USB).

First I installed the android ROM with a 15gb table ( shipped in the file created by mirek). After installing that I plugged in the created bootable USB drive and installed windows on it.

Repost: Try out Teclast's Android 5 final release (rooted, debloated)

I thought I would post this for anyone that might want to check out the Android 5 release from Teclast

Update: This post links to a new, TESTED archive. Previous version had a bad system.img

The following mods have been made to this release:

XML files and droidboot.img file modified so it will flash successfully using Intel Manufacturing Flash Tool with standard settings.

System image has been rooted. Latest version of SuperSU has been installed and multiple contingency files installed to insure SuperSU will not lose root.

Busybox has also been installed. All Chinese bloat that I could find has been removed.

This is meant as kind of a preview for Mirek's V5 which should be out at the end of the week.

V5 will be based on this release and I fully expect it will be Mirek's best release yet.

Enjoy !!

Sounds like a great idea. We do the shutting down automatically.

OK, I made the change. Thanks for the suggestion Mirek.
