Hey i wluld like to invite all member to take a look of my thread regarding windows installation issue please help me guys....
[Teclast X98 Air 3G] tecknight:
That is very good news to hear. The 2.05 BIOS we were aware of before yours does not appear to have GPS support

Update: I just checked the binary and look how recent the time/date stamp is:

07/20/2015 21:04:57 Ver: tPAD205

Compare to the previous 2.05 w/o GPS support:

05/05/2015 09:21:57 Ver: tPAD205
[Teclast X98 Air 3G] Crazy_Oni:
Hmm but do you think its wise to use it with an AIR II ?
[Teclast X98 Air 3G] pedralpi:
Bios or Android , that was the question!

Thanks for sending me the reference. Your acompaning tutorial is indeed quite easy and understandable. At that time I was looking for a solution of the disaperarence of , what I understood part of the bios, but it was probably just a wipe of Android, no more start buttons in the start menu. It seems now that it is just a matter of reinstall of a Android packkage.

The way you describe , on the X95 itself , without MFG, can it be followed also for reinstall Android?

Thanks for your time , Pedralpi

I think it had to be modded first for our air model. So that it will flash properly otherwise your device will brick:o
[Teclast X98 Air 3G] tecknight:
Yes, even if you have a Air 3G, I would advise giving [MENTION=2198172]mirek190[/MENTION] a chance to take a look at the image before you flash it.

It defiinitely looks promising, however..

TTT-Install or Upgrade the latest Xposed Framework to your X98 Air device

TTTTecKnight's Teclast Tutorials series

Install or Upgrade the latest Xposed Framework to your X98 Air device

Several of you were wanting to install the latest update for Xposed Framework, but the update is only availlable as a CWM or TWRP flashable zip. Since we don't have a custom recovery for the X98 yet, I created this installer using the embedded files and script from the flashable zip.

I also update or install the latest Xposed Installer and GravityBox (LP) apks during the install process.

This installer currently installs:

Xposed Framework V74 (updated 9/10/2015)

Xposed Installer 3.0-alpha4 (updated 6/29/2015)

GravityBox [LP] v 5.1.5 (updated 9/9/2015)

I will continue to update this installer to the latest Xposed Framework version available for Android 5.0. as new versions become available.

NOTE: if you have an older version of Xposed framework, Xposed installer or GravityBox [LP] already installed, the installer will update each component to the latest version.

I have also included an uninstaller, which will remove the Xposed framework mods (if present) and uninstall the Xposed installer and GravityBox [LP].

Procedure: Install Xposed Framework

Required:

A Windows host PC to run the installer on.

A rooted X98 Air device running Android 5.0 with busybox installed

A USB A to Micro USB cable

The Installer Archive:

Download installer archive

Step by Step Instructions:

Extract archive to a folder on your PC

Boot your X98 into Android and connect to PC via USB cable.

Browse to the folder and launch:

InstallXFandInstaller.bat to INSTALL the framework and apps.

or

RemoveXFandInstaller.bat to UNINSTALL the framework and apps.​

Both scripts create a detailed log of the installation or uninstallation and reboot the X98 when complete.

I have tested it pretty extensively on my X98 and I did not encounter any problems.

Just to reiterate in case you didn't notice a post above...

***Saved BIOS backups MUST be modded to flash correctly.***

I learned the hard way.

As mirek190 shows here, the mod is to change 2 values with a hex editor:

[Teclast X98 Air 3G] tecknight:
Thanks for the info, billbmsn

The values were in fact FEFE. I changed them to FFFF.

I then successfully flashed the BIOS to my C8J6.

I am happy to report:

Cameras, GPS and 3G Networking are ALL working in Windows and Android.

Of course they were working for me on 2.02 as well

and Select OS button is in English (says OK)

I am attaching a FLASH205B.ZIP archive which will flash 2.05B (as I am calling it for now) safely.

It includes the modified BIOS image and the flashing script.

Download FLASH205b.zip

As @ jsager33 was quick to report (Thank you!!)

Flashing this BIOS image causes Windows 10 to immediately lose it's activation.

I even tried nulling out the embedded Windows key, as it was set to xxxxx-xxxxx-xxxxx-xxxxx-xxxx2,

but it did not help. Flashing back to 2.02 did help. I find it interesting as my Windows 10 is not activated based on any software key, it is activated based on the fact that it formerly had a valid, activated copy of Windows 8.1,

and it is uniquely recognised by the Windows validation servers
[Teclast X98 Air 3G] jsager33:
[MENTION=2651082]tecknight[/MENTION] beat me to the punch. I modded the 2.05 bios file and successfully flashed it on my HG9M Air II. As he noted, Select OS button is in English and Cameras are working in Windows and Android (as they were under 2.02 as well on my tablet).
[Teclast X98 Air 3G] Mikha777:
I don't use Android at all, if i understand you don't have android partitions installed so at the boot time it ask to you which OS to start Android or Windows , so you see the Android Icon but to have it to work you must have installed Android.

I don't know exactly how Android partitioning works AND if you install it AFTER Windows I'm not sure if it will erase your Windows Partition.

If you decide to keep only Windows and want to remove the menu to boot direct on Windows just tick the tiny box in the upper left corner of the boot screen and next reboot will be direct to Windows. ;)

the old 2.05 bios didnt have this issue.
[Teclast X98 Air 3G] Lordof9:
Hey,

as i said before i was able to run my Windows 10 for about 7h without battery drops. So i tested it on Android the same way (Display always on (this time brightness set to min.) , Wi-Fi on, plane mode on, only laying around and illuminating my room. I was running this "test" on my X98 3G (2.05) with mirek's Lolipop Android (v5.0) and on a X98 3G (2.02) with mirek190's KitKat Android (v4.2), both C5J6.

Both tablets were running without (one exception) battery drops and no sticking to any specific percent. The 5.0 suddenly had a fast drop (but was not jumping to) from 28% to 15% and the battery saver kicks in.

Also i noticed both tablets are super different for the Wi-Fi and the Display consumption. The 4.4 had almost no (3%) Display consumption but a huge Wi-Fi. The 5.0 almost no (4%) Display and 72% Display consumption. So why is that? The 5.0 was suffering from this "calculated to high" (last entry, dont know what it is really called in the english Android).

This straight battery line on Android is strange to me because hat some big battery drops in the past on my Android 5.0 device. I dont have the Andoid 4.4 device long enough to tell if there are the same drops in battery life.

Is anybody having this drops on the stock ROM (4.4 or 5.0)?

Rather, the X98 Pro seems to be an inconvenience choice to do (at the moment) because of its thermal and throttling problems.

Hi Tecknight,

are you able to create a script to auto-add Windows product key in that bin file before to flash it? (in order to upgrade bios and still have Win product key in bios too)

I bricked my tablet using Toolbox. Got all the staff to flash the bios (the programmer, the Clip and a new Winbond chip). Done that but still the tablet doesn't start. Any ideas guys please. Thanks. Bruno29
[Teclast X98 Air 3G] jagr:
tried already, doesnt work as well. no issues with the 2.02 bios and older 2.05 bios though.

was unable to find the product key in those to try injecting.
[Teclast X98 Air 3G] Nathaphong:
I resolved the problem by setting the cpu at 400 in "/system/etc/init.d/gpu-fix" . Use Es file explore to do it.

Now the only problem in Lollipop is battery drop.
[Teclast X98 Air 3G] tecknight:
There is NO key you could inject. If you have Windows 10 upgraded from 8.1, your Windows 10 key is a generic key.

Your activation is due to the Windows activation servers recognizing your tablet as a device that was legitimately upgraded to Windows 10. Based on what I have been reading, the reason we are losing activation, is that updating the BIOS image is causing Windows activation servers to no longer recognize the tablet (activation server thinks the hardware has changed).

There are a number of posts on the internet of this exact issue, like user updates his laptop's BIOS and suddenly is deactivated

FYI, mine didn't immediately reactivate when I flashed back to 2.02.

I got an email from microsoft about "suspicious activity" and Windows wouldn't reactivate until I entered the security code that MS emailed me

If freezing in games ( I assume you made clean install ) you have to decrease gpu speed more - in my rom is 580 mhz .

Try 550 or 500 in /sysyem/etc/init.d/gpu-fix.

Just change values inside the file.

X98 air 2 upgrade

Hi

Bought the X98 air 2 Dual boot(HG7N) and I have one share and one request

I successfully upgraded to Win 10 trough the regular Microsoft process.

Downloading took very long. few hours. Since there is not enough space on the disk, you have to connect external USB drive with at least 9G free.

The installation goes through some screens in Chinese, I next hit the right button which I assume was Next, and then English took place. I was afraid to stuck with the Chinese version. Maybe because in 8.1 the interface langue was English, and I also changed the Location to Israel. anyway, the end, all good . Win 10 is much "touch oriented" than 8.1. seems like is works well.

Now I want to flash an android rom. Mainly to remove all Chinese stuff' and specifically to try improve the brightness. I need it as low as possible.

I need a clear instructions. and couldn't find it.

I did try to install on Win7 the MFT as explain here http://xdaforums.com/showpost.php?p=61847947&postcount=10126

Looked like installation succeeded but the tool is not running.

The error message says "Program cant start because wdapi1140.dll is missing from your computer"

Advise?

[Teclast X98 Air 3G] tecknight:
Sorry to hear that man, I am certain that really really sucks.

Good luck getting it reflashed as soon as possible. As I understand, it's not too difficult.

The toughest part, they say, is getting the clip on correctly.
[Teclast X98 Air 3G] Mikha777:
It's not really difficult and CH341A programmers can flash ALL the new UEFI based firmware, so I bought those 2 from the same seller ;)

Sooner or later it was bound to happen with all the experimentations I've done. :cyclops:

Less than $10 and it will be useful for other projects too, my only regret is that

I should have ordered one long ago...

:p
[Teclast X98 Air 3G] tecknight:
That message means you need to install the iSoC drivers.

You can DOWNLOAD them here

Just extract the executable installer from the .zip and run it on your MFT PC.

You were using an old tutorial. This one here is updated:

[Teclast X98 Air 3G] Mikha777:
I have found the guy who wrote the software for most of the "cheap" CH341A, so if you like to read about the technology and know how those programmers works here's the link in English: http://see.sl088.com/wiki/Lai_Green_Tool

But the Chinese original version here http://see.sl088.com/wiki/CH341A_编程器 is a lot better and complete. you can use Chrome with the automatic translation it's very accurate for the Chinese. :cool:
[Teclast X98 Air 3G] billbmsn:
In my experience with the external flasher, the first time worked so easily I thought unbricking was a no-brainer. Then after that it seemed to get progressively harder after each bricking to get a good flash. Some of it may have been due to wear/bending of the tips of the clip contacts. So, yes, I would recommend anyone buy two, like I did. Even after what looked like a successful flash, the verify step would fail over and over. Once I just ignored the verify results and the BIOS worked anyway, but most of the time it did not. So, I kept at it until I got a good verify result. The clip seating was part of the problem. Make sure the software can identify the chip. If not, check/change the clip. Auto programming worked sometimes and failed others. I usually resorted to manual mode, which requires waiting at least 10 seconds between steps, it appears. But sometimes Auto mode would work after manual failed. Go figure. The last unbrick took so many tries, I'm afraid to flash anything but clean factory BIOS for my specific model (HG8M), of which there really isn't any. Teclast support is rather threadbare.

Flashing the bios

Hi, I can't get my tablet teclast x98 air c5j6 back to life after flashing the bios several times successfully. I bricked it using Toolbox trying to update the bios and now is completely dead. Any ideas or suggestions? Thanks
[Teclast X98 Air 3G] mirek190:
This the only way to repair it unfortunately ... ultra smooth or sometime blinking status bar ...
[Teclast X98 Air 3G] Plicha:
Ok, most likely I'm guilty of the issue. I didn't want to loose all programs so I did upade without wipe. Everything works fine and smooth besides camera, clock and random freezes. Additionally I cannot edit gpu-fix file. Once I give it a try it says that file doesn't exist (ES File explorer). Solid Explorer doesn't see the file at all.

So...I should wipe my tablet, right? ;)
[Teclast X98 Air 3G] mirek190:
First try to edit that file ( your the file explorer needs a root access - rw )

If freezes still happen then make a wipe data .
[Teclast X98 Air 3G] Mikha777:
Hi Bill,

From what I read last night about CH341A flashing software, it's easy BUT like you tell you must have a very good contact between the clips and the chip but it's not the only factor that play. :silly:

The version of the software/driver you use play a big role too, some version will work better on system with more RAM other will work better if you reboot the computer between the flash of Firmwares. Take a look at the links in my previous post especially the Chinese link I learned a lot about the software part.

Also

ideally

you must have the chip unsoldered but that's not easy if you don't have the tools. Flashing the firmware in place on the board sometime can't have enough AMPerage (

NOT voltage

) for the flashing process.

The CH341A provide the current and it take it from the USB port with a max output of 100ma, 100ma is enough if you flash "standalone" chips but when you flash firmware direct on the board sometime it's not enough cause you need to provide current for the whole section of the firmware on the board to have the flashing process successful.

That's why (from what I've read) when we flash chips

in place

we don't have always the same results from one time to another. :cowboy:

Soldering direct wires to the firmware to have a very GOOD contact can be a solution to have the best contact possible. If I have to do it I will leave the small lead soldered to the chip/firmware after the flash but covering them after to prevent a short :p.

If you doubt about the verify result after the flash you can also use an external software like ExamDiff http://www.prestosoft.com/edp_examdiff.asp to confirm the results with the source file (.bin or .bios) and the chip.

Having a higher voltage will not play a big role in the success of the flashing process but can destroy some components if it is to high... From the peoples around it seem that it's not really a big issue with the flashing of X98 :cyclops:

Regards :)

---------- Post added at 12:29 PM ---------- Previous post was at 12:24 PM ----------

If it's bricked you will have to flash the firmware if you want to unbrick it, for less than $10 it's not a big risk ! ;)

flash the firmware

Hi Mikha777 , thank you for answering. What do you mean "to flash the firmware", is it something I can do it myself? Here's briefly what has happened: after I bricked the bios I bought the CH341A programmer, the clip and a few of Winbond chips Eprom. I programmed the chip first then soldered it on the board. The programming of the bios has been always a success. I also tried the "Manufacturing Flash Tool" software. That is it. Now I'm stucked with this problem and I don't know what to do.

How do you have removed the firmware from the board ? With wik ?

[IMG="Wik"]http://i.imgur.com/iVjCgQq.png[/IMG]

Have you been successful one time in having the X98 come to life after the first bricking ?

Maybe you heated the board (PCB) to much and damaged a trace from a layer of the board ? A good and old trick to see if trace are damaged between the layer is to use a spotlight in front of the board, it will allow you to see more easily the trace between the layer.

Have shorted something ? Have you removed the battery first before removing the Firmware Chip ?

BIOS 2.05B images

Some of you were asking for the BIOS ver 2.05B safe to flash image.

Special note before you flash: If you are running the free Windows 10 upgrade, then EXPECT any of the 2.05B images to cause Windows to lose validation. The BIOS changes appear to cause the Windows validation servers to no longer recognize your X98 as the system that updated to Windows 10.

It's OK, restoring BIOS 2.02 will re-validate your system.

Note: All images modded to be safe to flash.

This is a BIOS flasher archive with multiple BIOS images.

Images included are:

BIOS202.bin - ver 2.02 Dual boot

BIOS205A.bin - 'A' version 2.05 w/o GPS support

BIOS205BKR.bin - BIOS 2.05B Windows key removed *

BIOS205BNK.bin - BIOS 2.05B Windows key set to NULLS

BIOS205BXK.bin - BIOS 2.05B Windows key=xxxxx-xxxxx-xxxxx-xxxxx-xxxx3

* This is default image

Set the image to flash by browsing to folder X98-Air-dual-boot-bios-and-FPT

Hold down shift key then right click an empty area in the file list and select Open Command Window here

In command window type

SETBIOS [imagename]​

[imagename] should be one of the BIOS image names above:

eg:

SETBIOS BIOS202 results in:

1 file(s) copied.

BIOS202.bin set as BIOS image to flash.

Run FLASH.BAT to flash BIOS
