All the new BIOS's seem to break getting into droidboot mode.

You can still boot into it with

adb reboot bootloader

I use "minimal adb and fastboot" program.

The lite rom for C6J6 rocks. Saves heaps of space and standby battery performance is really good.

Just change the launcher if you dont like the included one (which I dont )

I want to flash dual boot BIOS but I'm on 4.4.2 ROM and there is no IFWI update in this version of Android :P

Should I do the same as in instruction Android->Win but just use the dualboot file? ;)

SOS on FW update!!!

SOS mates,

I've used UpdateIFWI on android (c6j6) to update to ver.2 of BIOS and after 50 minutes it still says

"Upgrading, this may take up a few minutes...".

PLEASE ADVISE!!!!:(:(:(
[Teclast X98 Air 3G] SUMMERBREEZE:
what do you mean here? you mean dualboot bios?
[Teclast X98 Air 3G] soudara:
Force stop app ifwi and retry with the same file in internal storage no sdcard but no power off tablet

Stop all other app before flash

If the flashing not complete correctly force stop and retry with stock bios file very important no reboot or power off your tablet if not complete because brick your tablet

thanks I'll try it!!! How long usually it takes?

---------- Post added at 09:36 PM ---------- Previous post was at 09:33 PM ----------

No, no just stock BIOS ver 2. from TECLAST.

How long does it take to upgrade the BIOS through UpdateiFWI?
[Teclast X98 Air 3G] SUMMERBREEZE:
20-25 seconds i think :silly:

try to force close the IFWI app and try again with the previous v1 bios. be sure you have flashed it before rebooting tablet, otherwise say bye bye to your tablet :eek:

no no im joking, everything will be fine :good:

I has still a problem with the air x98 , install the dual bios ,and when I tried to install android with the new partitions table I have problem. [FAILURE] OS flash failure ADB ENUM failed , reinstal drivers , even I install on virtual machine windows 7 (i have 8.1 ) and the same story.

What me to do ? ROMs android in x98 (not air) install normally .
[Teclast X98 Air 3G] mirek190:
Don't worry I had the same problem .

I was waiting in UpdateIFWI about 1 hour and tying several times on android 4.4.2 - then I restarted the tablet ( crossing fingers 2x ) and was fine - bios wan't touched.

Use better TOOLBOX on your PC - first root device via this app then - flash bios ( just replace BIOS.bin in BIOS folder on what you want bios file)
[Teclast X98 Air 3G] ambrosio5:
Oh I see, sorry my ignorance but what is TOOLBOX?

There is a bios update when you upgrade to 4.4.4

There is no bios update for 4.4.2, only the dual boot bios.

[Teclast X98 Air 3G] ambrosio5:
I'm on 4.4.2. I tried to UpdateIFWI the dual-boot bios but with no luck.

It does not work. So I'll try with the help of toolbox on my laptop.
[Teclast X98 Air 3G] SUMMERBREEZE:
It is actualy a ROM, it means operating system, the one you are using , it is the official ROM by Teclast and from fabrique. We are going to flash into tablet the lighter version of it. which has no chinese bloatware and also some performance tricks and keyboards etc..
[Teclast X98 Air 3G] mirek190:
You do not have to even uninstall that google play store..

BUT first you have to reflash rom again because you tried login play store first - that's why any method not now work.

I had the same problem.

After reflash rom - make root by Toolbox - then install Link2SD. move playstote to system apps and THAT'S IT
[Teclast X98 Air 3G] Cozla:
I’m little confused on post #4 for C8J7 model on point no 7 we can read:

„Open partition.tbl with notepad++and find this entry:

'add -b 4948008 -s $calc($lba_end-16384) -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0'

and replace it with this other:

'add -b 4948008 -s 16384000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0'

Then save it ,this last action dedicate 8 gb of rom space for Android and you can install windows in 18.5 gb free rom space.”

First of all in partition.tbl to the literom for C8J7 there is no entry like :

'add -b 4948008 -s $calc($lba_end-16384) -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0'

Secondly in edited partition.tbl for C8j7 attached to post #4 there entry is:

add -b 5931048 -s 16384000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0

So what is the correct entry for C8J7 in partition.tbl after edition?

'add -b 4948008 -s 16384000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0'

or

add -b 5931048 -s 16384000 -t data -u 80868086-8086-8086-8086-000000000008 -l data -T 0 -P 0 /dev/block/mmcblk0

reload /dev/block/mmcblk0

How do we do this then please
[Teclast X98 Air 3G] seba2000:
I have a quick question: are there any other advantages of having dual boot bios except the obvious one (dual boot)?

I'll use Windows as primary system (not need Android actually) so I am just thinking that loosing almost 10Gb of space just to have dual boot is not best option for me.

I am just wondering if this bios have any other advantages (like working 60Hz refresh rate, 3g, GPS, etc.) in compare to standard one?

In other words, Windows will work better on this bios or it doesn't completely matter?
[Teclast X98 Air 3G] Grayie10:
How do we do this then
[Teclast X98 Air 3G] supercowz:
yep of course win8.1 will run better with the latest bios even u dont use dualboot, u can only use win8.1 with it ...

is there any X98 Air 3G (C6J6) lite rom arround ???

i need one to made some testing .. thank you ..
[Teclast X98 Air 3G] seba2000:
Thanks for quick reply. As I understand it is possible to use that bios (dual boot) with option to install only one system with all available space (almost 32Gb)?

Please, correct me if I'm wrong...

And if I am, is it really worth to lose 1/3 of free space just to have this bios? (that is important for those who would like to use Windows only)
[Teclast X98 Air 3G] supercowz:
bios is a bios, not related to you 32gb, if you install just win8.1 you will have full space ....

New Bios -> additional advantages on Win 8.1?

I actually have the exact same situation or question, but related to the Windows battery meter on 8.1. On my C6J6 I "suffer" from the issue reported by Hendrickson, that the meter goes down and then keeps stable on a low (7%?) level for a while? Does any new Bios (or drivers) fix that, or did I miss any fix?

you can also flash LITE ROM for your device and try like that :fingers-crossed:
[Teclast X98 Air 3G] Hendrickson:
It's a very annoying fault/bug for sure, I read on Youtube from a comment that it also effects some Air II units, I think it's not bios related, but it is a hardware issue with the battery ic that controls the metering of the battery. Something to do with that is faulty. Your best to ask your sell from Aliexpress for a replacement.

If not not, when you hit 7% you have really hit 50% and should have a good 3 hours more. (Depending on what your doing, brightness or if your gaming etc.)

More comments I've had from Youtube, I've been told that there are many out there that have the touchscreen lag issue. Teclast just ship them out and hope people don't return them

Can't stress this enough, our touch screen should be IPAD smooth, if its a little laggy or stutters you have a bad touch panel.
