[Teclast X98 Air 3G] Wootever:
It doesn't matter if it's fpt on android or fptw on windows as both are doing the exact same thing.

The android flasher just copies the fpt binary to the device and executes it from the local command shell:

adb push X98-Air-3G-Bios-files /data/local/tmp/
adb shell "cd /data/local/tmp/"
adb shell "fpt -f X98_Air_3G_Dual.bin -y"

(-y means it will not prompt if a warning occurs)

The problem is most likely an incompatibility with older variants.

Revisions confirmed working:

C5J5, C5J6 and C9J8

Revisions bricked:

C8J6

X98 Air 3G:
C6J6 - Android (32G) - [camera inversion problem]*
C6J7 - Windows (32G) - [camera inversion problem / genuine problem]*
C7J7 - Dual (32G) - [only 200 units sold]
C8J6 - Dual (64G)
C8J7 - Android (32G)
C9J6 - Dual (64G)
C9J7 - Dual (32G)
C9J8 - Dual (32G)
C5J5 - Dual (32G/64G)
C5J6 - Dual (64G)

It might be also possible that the bios has to be erased before the flash procedure. (likely caused by mismatches due to changed bios layout)

Backup current bios (it's important so save this backup on an external storage):

fptw -d backup.bin

Erase flash:

fptw -erase

Flash new bios:

fptw -f X98_Air_3G_Dual.bin

In tried flashing Air II bios (ver 2.01) on my HG9M via the Android method being discussed and shut it down holding the power button. I ended up with a brick. EEPROM programmer should be here by Tuesday to fix. I made a backup of the original bios before flashing and saved it on external flash drive. I just need to make sure I use the programmer properly. I wonder if there is something to be said about erasing the original bios first before flashing the new bios.

I am curious to know if anyone successfully flashed the new bios on an HG9M. Details of how it was done would be welcomed. I'll keep notes on what I do with the programmer and post it back here.
[Teclast X98 Air 3G] SkOrPn:
There is a rumor going around that Chuwi is releasing a 64GB model of its vi10 called the Chuwi vi10 PRO. With 2 full size USB ports that sounds excellent to me. I might just wait to compare it with the Teclast X98 3G.
[Teclast X98 Air 3G] mcjamez:
I have successfully flashed 2.01 onto 3 HG9M's. I did it in Windows 8.1 on the tablet using the flasher.bat from Teclast in the Android 5.0 beta thread on the Teclast forum. All of the required files came in a .rar file including the 2.01 bios, the flasher.bat, and the bios windows key backup/restore program. I just followed the directions in the Teclast thread and it worked every time.

I also didn't do a hard reboot after the flash, I just rebooted from windows. Again, worked every time. I see a lot of "do it exactly this way" posts, with no explanation of why the "way" is right. Most of those are followed by "I did it that way and bricked my tablet". I'd say do it the way the manufacture suggests for the greatest chance of success.

[Teclast X98 Air 3G] janders:
I successfully flashed 2.02 on my C9J7 from win8.1 on the tablet using: fptw -f X98_Air_3G_Dual.bin

After flashing, I rebooted using hardware reset (i.e. press and hold power button until the tablet completely shuts down) - I don't know if this is really needed, though.

Everything seems to work , except that I still have terrible battery drain in standby mode. Why? Wasn't the 2.02 bios supposed to solve this problem?

Do I need to update some drivers as well in order to reduce battery drain? Or change some settings? I'm still running the original Win8.1 with Bing.
[Teclast X98 Air 3G] mcampbellsmith:
Jim, Is this the thread you followed? http://bbs.teclast.com/thread-397112-1-1.html and is this the bios update you used? (http://pan.baidu.com/s/1hqAcDA8)

Got a C8J7 32Gb model, turned to dual boot some time ago. I did not use the Windows installation a lot, but I'm a bit lazy to reformat to allocate all space to Android.

In any case, I'm running out of available app space for Android. I thought I could use an SD card to move apps to SD, however this is not possible, since no move to SD option is given.

If I recall correctly I did not hide the partitions from Windows side (as per the dual boot howto's suggested), since Android seems to be working just fine.

Any idea what might be wrong here?
[Teclast X98 Air 3G] BoORDeL:
personally I don't like the 16:9 ratio,I prefer 16:10 or 4:3 .

In addition, the resolution of the display seems to be 1366 * 768 .

If you need dual boot 16:10 tablet go for X10.

---------- Post added at 08:38 ---------- Previous post was at 08:31 ----------

There was a discussion about your statement: link2sd offers the option to moove apps to sd in the pro version only(please correct me if i am wrong) and you have to be rooted.
[Teclast X98 Air 3G] SkOrPn:
Yeah I would prefer 4:3 as well since I'm mainly a reader, skyper, and almost never watch videos on these things. I just like the looks of the Chuwi about ten fold over the ugly white Teclast. The full sized USB are nearly a must for me for creating bootable images. However, I want the retina screen, and the GPS+Glonass of the Teclast.

I wish these two devices would have a child of its own with all the features from both, lol... I LOVE the glass on both sides of the Chuwi, just love that absolute flatness like the Dell Venue 8 Pro 7000 has.

EDIT: And one last thing, the Teclast having a strong XDA presence and aftermarket ROM following is also another must. The support alone demands going with it.

P.S> However, tomorrow I am picking up and brand new TAB S 8.4" for only $190 with the original Samsung case, so this device is now on hold unfortunately :( There is no way I can say no to a MUCH more premium device for less money. I really wanted a Dual Boot tab too.

I'd go for it too ;) , although i don't like exynos 5420 SOC.

Yeah, but I don't know why I feel sad. I been wanting the TAB S for a year now and all of a sudden my brother finds me someone who has one practically brand new still in the retail box with slight use (said he used it twice, but that has to be a lie lol) and the original Samsung cover. The only reason I am picking it up is because he really needs the cash and I can't get myself to look the other way on that device at that price. Now I'm afraid I am going to have to get the Teclast just for Windows, lmao.
[Teclast X98 Air 3G] BoORDeL:
Maybe you got a defective GPU.

Have you tried under android to lower GPU max frequence (about to 400)?

If the answer is yes and you can't ask for a substitution for defective part you have to follow acc007 tutorial and add termal pad to components to better heat dissipation.

[Teclast X98 Air 3G] royeiror:
in Post #2 there's a section called "WINDOWS 8.1 => ANDROID PROCEDURE (thanks to Frontier)"

You need to follow those instructions, there are quite a few ROMs and each will have pros and cons, although I dare to say that most of the people in this thread are running one of mirek190's ROMs, which you can find in his Google Drive Repo. It depends if you want to mess with partitions and such but there are 3 xml files to choose from. one wipes everything, the other wipes only android, and the other just upgrades android.

I have an HG9M and use mirek's V3 ROM, Although it's compatible with my device, it has a few quirks. First the cameras don't work, second the device info is for one of the 3G models, aside from that it works great.

2.02 Bios on C6J6 (does it really solve the Windows battery drain in dual boot?)

Hi Mirek190,

Thanks for all your great work in Teclast x98 Air 3G!

A small question since you say that you flashed your old c6j6 with 2.02 BIOS. Did it solve the infamous windows battery drain problem in dual boot?

Because I keep getting ambiguous info from this forum. Some say it does solve it, other say it doesn't.

What's your opinion?

I also have a dual boot c6j6 but with the old BIOS. Should I pass ver 2.02, is it worth it?

Thanks again for your great ROMs! Looking forward to Lollipop 5.1!

In that case you can use pc to flash bios if not works in android .

Or flash 4.4.4 and then use that app in android .
[Teclast X98 Air 3G] royeiror:
You could use the Teclast ROM, although I'm not sure it has the 3 xml files, so you might have to fiddle with some more settings. With mirek's ROM, you choose between the 3 xml files and you can keep your tablet like it is.

mirek does suggest you wipe android when upgrading from 4.4 to 5.0, but that's up to you.

[Teclast X98 Air 3G] Superjets:
Here's what I did, hope this helps, you need the tablet, usb cable and a Windows pc.

Download Mirek's flasher seen everywhere in this thread. Unzip the package somewhere on your pc.

On tablet

-Make sure your tablet is rooted and usb debugging is on (VRoot instructions link in second post)

-Tablet must be in Android

-Remember that you will lose your windows activation key so write it down before this

On desktop Windows PC

-Rename the folder to something shorter, like just bios (my flasher did not recognize the long folder name.. this helped)

-Install package's adb.exe, it just flashes on the screen

-Connect tablet to PC

-Press FLASH.bat

-Press any key, choose option 2, do what the flasher says

-Takes about two minutes, processes seen on the screen, ends with "Flashing bios is finished!"

-Turn tablet off with pushing the power button for 10 seconds, not from android

-Flashing completed!

In my case the black command screen with single blinking line was because the device was probably not rooted properly. I rooted it again with VRoot and yeah, it worked.
