Hey teckight im facing an issue my tab x98 c8j7 is not booting it was perfectly working yesterday and a day before yesterday i flashed dual boot menu and was working fine but yester day whole day it was on charging and in when ehn i saw it was off and from night till today's morning its still off... Im worried guide me what could possibly went wrong.
[Teclast X98 Air 3G] cattolicboy:
Hi tecknight, thanks for your modded bios.

Since Teclast doesn't provide the changelog of their updates, have you noticed any improvements between 2.02 and 2.05 (example: fix battery drain, fix incorrect battery meter etc)?
[Teclast X98 Air 3G] kostas-k:
First of all, thanks for the latest BIOS file. After upgrading my tablet, I have problem with the Suspend option and when I switch off the tablet, it doesn't turn on immediatelly. I must reset the tablet before trying to turn it on or wait about 5 minutes and then try again. I have unchecked the option in windows to fix it but no luck.

Returned to 2.02
[Teclast X98 Air 3G] jagr:
i noticed there was a battery drain after power off with 2.05. about 20-40% overnight. i think its not in the fully off state, that was why you cannot turn in on. if you leave the charger plugged in and shut it down, display is never fully off until you power down with a 10-15s press. i have the same issue, have to fiddle with power switch a few times before i could get it on. back to 2.02 for me as well. have a C5J6 unit.

Hey tecknight,

thank you for providing these versions of the 2.05B bios.

But which one should I use if I got a x98 with windows 10 preinstalled?

(my acutal bios version is 1.07)

thanks

Hello everyone, I have a problem with the cameras, I came from the Air3G bangood 4.4.4 and Windows 10 with bios 1.07 (not if it is more ancient than modern or 2.02 or 2.05) cameras in android running but windows the front does not work, back when I put the last lollipop mirek and change bios to 2.02, a result, they are not going cameras w10 android and only the back, this is it? Is there any solution ?, in Device Manager in Windows I get error ov2680 camera, I uninstalled and installed the drivers several times but the result is always the same, because some people do well the cameras and others are not going well is a mystery, bios 2.05b would solve the problem? any suggestion would be helpful. thanks in advance
[Teclast X98 Air 3G] majkel_94:
The same problem on 2.02 on C6J6... you could try disable fast startup :P
[Teclast X98 Air 3G] jagr:
is this the fast startup in windows? or quiet boot in bios. i dont have that option since my hibernation is disabled. will try it via registry tweak. this happens during an android shutdown as well.

will report back if it solves the issue.

edit: the problem persists. guess its fine if you hardly intend to fully shutdown the tablet.
[Teclast X98 Air 3G] kostas-k:
I had done it but no luck...
[Teclast X98 Air 3G] B0IIE:
Now I got a bigger problem. I flashed one of mireks roms today and must have picked flash-full_with_REPARTITION.xml instead of flash-system_only_WIPE_DATA.xml. Now my windows 10 is gone and I don´t know how to get it back. I allready created a usb with MediaCreationTool. The usb shows up in bios but i can´t boot from it. What am I doing wrong?

Teclast Battery Issue

Hello,

I would like to talk about my issue with the battery of my Teclast Air II.

I have the same issue as tecknight, the design capacity was reduced to 14,440 as well a few days ago when I updated the bios to 2.02. (not totally sure it was because of that, the day fit).

I did install the rom of lollipop as well on that day, fallowing the tutorial from this forum.

So I was wondering if someone managed to fix this issue please ?

I was going to update to windows 10 as well, maybe I should start by doing that ?

Regards.

Hi, this can work with dual boot system? the procedure is the same?
[Teclast X98 Air 3G] .oOOo.:
I'm not using mirek's ROM, but I had the same problem. If you set the resolution to 1920x1080 in the HDMI settings the image on your TV will be displayed with black borders.

If you install secondscreen from the Play store, you can define custom display settings. If I choose 2560x1440 the image on my TV is fullscreen. Text is too small for me though so I manually tweaked one of secondscreen's settings files and changed the resolution to 2134x1200. If I choose 1920x1080 the home and back button at the bottom of the screen disappear. This might be different on Mirek's ROM.

Don't worry about the fact that the resolutions are larger than your screen sizes. Android will use the real resolution of your displays. The larger resolution will only change the size of icons and text on your screen. Don't go crazy though with using extreme settings. You could end in a crash loop. Make sure that you can restore settings from either Windows or adb if things get out of hand,
[Teclast X98 Air 3G] raffy01:
Hello, this is my first post on this thread :o

Just to say that I received my tablet, I was surprised that it was on Android 5.0 :good:

So I think I can only root it and uninstall all chineses app or do you think I have to install mirek's ROM ?

Thank you.

but now back to my first question. Which of the bios 2.05b version do I have to flash when I had win 10 already pre installed?

I downloaded the app and used your settings and everything is working as expected now. I also modified the option to actually turn off the screen when the cable is plugged in (I typically use a USB air mouse when I plugin the tablet anyway). It's an extra step to open the app and select the profile but it's allowing me to use the tablet in android now without having to switch to windows. Thanks again

you will keep you Windows license but GPS will not work at this time and with

you will lose your Window license (unregistered status) but GPS Work.

[Teclast X98 Air 3G] Ashenfall:
Just a query - 2.05B - does it still appear as 2.05?

Only reason is I just bought a new tablet which says it has BIOs 2.05, and the feeling I get from reading here is that there might be two versions of 2.05, and people have labelled the second one as B?

My HG9M Air II had this issue on the first day. The day I got my tablet, which was 2 weeks ago, I flashed to 2.02 and installed Mirek's v5.0. I have always thought that full charge capacity is the one to look at and not design capacity. How much are you getting out of your battery life? I am averaging about 4 hours on Android and maybe 6 hours on Windows 8.1
[Teclast X98 Air 3G] billbmsn:
What model and model ID (on back of tablet)?
[Teclast X98 Air 3G] Seiya0890:
Thanks for your reply, At the begining, both (designed and fully) were at 31160. Right now if I charge completly for 8 hours, the fully charge would still say something like 31100 mwh, while the design is at 14440. As for the battery, in Windows 8.1 I am not actually sure, but I think it was more than 6hours.

Hey everyone,

i got a second X98 Air 3G for the family (C5J6 with firmware 1.07). In Android 4.4 (stock) i noticed the speakers were playing a white noise. The normal sounds were there but also this white noise in the background.

I flashed mireks Android 4.4- v4.2 and thought everything is fine now but today the white noice is back. The white noice is there everytime the tablet plays a sound, i press a button (softkeys) or open a app. It is about 3-4 seconds long. The tablet is on tecknights 2.02 BIOS now.

This only happens in Android not Windows 10. Is this a problem only on Android 4.4? I dont have this problems on my Android 5 Air 3G.

Any ideas?

Hi everyone!

Got my Teclast X98 air 3G yesterday with Win 10 + Android 5.0.

I left Win 10 untouched, but flashed Mirek's v5.0 (thank you very much for the ROM!!) to get rid of all the chinese bloatware.

Everything works very smooth except that I am experiencing really slow WiFi speeds on Android compared to e.g. my Xperia ZL.

Could anyone help me with that issue?

I suspect bat file to copy ini files isnt doing anything. Earlier also i tried copying those files in x86 program files MFT folder manually only. Though i didnt know about programdata folder. Now have copied both ini files to C:\ProgramData\INTEL too. I hope its correct.

Giving it a try again this time after reinstalling everything. From drivers to MFT which i have done countless number of times. Only difference i am making is copying ini files in C:\ProgramData\INTEL folder.

Out of curiosity, did you have the files in a folder path that had spaces in it somewhere within the full path from the drive (C:\) to where the files were stored?

Which Drivers/version do you use ?

From there we will go step by step and I'm pretty sure you will succeed at the end :cool:

---------- Post added at 06:49 PM ---------- Previous post was at 06:38 PM ----------

Yes try with the UEFI method :cowboy:

There is no more risk to brick your X98 than with any other methods if you follow the instructions.

You do it from the same computer/tablet so no no cable and No other computers involved :cyclops:

Just

DON'T forget

at the end of the process/flashing to shutdown the tablet by pressing the Power button for 15 seconds ;)

How Flash your BIOS via the UEFI shell:

You connect a USB hub to your tablet and connect a Keyboard to the hub and a USB key with the

BIOS file

+

FPT.efi

command and the

fparts.txt

on the USB Drive.

Important:

To be recognized by the UEFI SHELL BIOS the USB must be formatted with GPT AND in Fat32, the more EZ is to use the RUFUS utility to format the USB drive. So don't forget to format the USB drive before copying the files ;)

You power up the tablet and press "ESC" key to enter in the BIOS.

In the BIOS you go to the Boot selection and choose "UEFI Shell"

You will see a screen like this:

You press any key to have the SHELL prompt (There is not Startup.nsh on tablet it's a generic message in UEFI bios)

You are now in the UEFI shell, it's a littel bit like the old DOS shell.

We now need to know where is the USB drive so you will type "map -r" (Without the quotes)

It will list all the devices available:

You try to find your USB drive, usually you will see "Removable Hardrive" in the name somewhere.

To be sure you have the good device you type at the prompt:

"ls FS1:" (Without the quotes) and press "enter"

It will list the files so if you see the BIOS file and the fpt.efi file you are at the right place if not try another device FS1 FS2 etc...

Once you are in the right device it's EZ:

First we will do a back-up of the BIOS, so Type:

"fpt.efi -D MyOriginalBios.bin" (Without the quotes) and press "enter"

It will do a backup of your bios named "MyOriginalBios.bin" saved on the USB drive.

Now we will Flash the BIOS so type:

"fpt.efi -f MyNewBios.bin" (Without the quotes) and replace MyNewBios with the name of the bios file) and press "enter"

The process will begin you wait few minutes till it end and you should receive a message that the process was successful.

IMPORTANT:

At this point you shutdown the tablet by pressing the Power button for 15 seconds ;)

That's it ! Enjoy ! :laugh:

N.B.:

If you want to remove the Dual Boot menu

Link for Flash Programming Tool:

https://mega.nz/#!o4YADKZJ!Q1q3J8wSC9npX1ofrGE3iAwYEMAodREv1v-PhrJIXKI

For the BIOS you can use any BIOS from 1.03 to 2.05 ;)

Hey Mikha

I cant seem to create a proper bootable usb drive with rufus. I did select the GPT and Fat32 options but unselected create bootable disk using iso as I didn´t have one and copied the files to the stick.

Then I booted up into bios and selected UEFI: Generic Flah Disk 8.07 and not UEFI Shell as it wasn´t available and rebooted using Save canges and exit (or restart) and the tablet allways boots into windows

What am I doing wrong?
[Teclast X98 Air 3G] iGavB:
Hi all

So I have pretty much bricked my Teclast Air II and I have no idea how to undo what I have done. Essentially, I was trying to be clever and run just Windows 10 on my tablet, so I deleted all of the drives other than the main C:\ drive on the Windows partition, when I rebooted my Tablet it no longer boots, all I get is "Entering DnX mode. Waiting for fastboot command..." and nothing else.

As such I have tried to use the flash tool process etc to fix this, but that doesn't seem to be working either, below is a screenshot of my Android Intel Drivers installed and working on my Windows PC, the Manufacturing Flash tool with a flash file ready to go, BUT NO DEVICES FOUND :( Also when trying to run the fptw batch file, I get an error, also in screen shot.

How can I unbrick my Tablet :(

I think you have to use MBR partition scheme for UEFI. See the remark in:

Nevermind: You should use MBR for bootable USB sticks.

I used MBR (both version) in combination with NTFS and FAT32 and in combination with "create bootable disk using uefi:ntfs". But nothing worked.

[MENTION=3986785]Mikha777[/MENTION] The instructions do not work for me either. I do not have the "UEFI Shell" option in the BIOS settings. There is an "UEFI OS" and "UEFI: Generic STORAGE DEVICE" under Boot Override. Choosing either just flashes the screen and brings me back to the BIOS settings.
