theYuuhi,

If adb is not seeing your tablet, did you follow the instructions and install the intel adb drivers ?

If adb is still not seeing your device after installing the adb drivers, try a different USB cable.

---------- Post added at 01:39 PM ---------- Previous post was at 01:36 PM ----------

That's what happens when you flash with partitioning. It re-creates all the partitions including your Windows partitions.

---------- Post added at 01:46 PM ---------- Previous post was at 01:39 PM ----------

the Yuuhi,

I think you mean android won't boot and you can't get into droidboot mode.

DnX mode is built into all BIOS for the X98. You get to DnX mode by holding POWER and VOL+ and VOL-- until "Entering DnX mode appears in the center of the screen.

If you wiped your droidboot partition, it's not a problem. The X98 will load droidboot into memory when using MFT and a properly configured .xml file
[Teclast X98 Air 3G] theYuuhi:
The thing is, i'm install adb drivers and successfully flashed X98 Air 3G 4.4.4(C5Jx) mirek190_v4.2. After that i try to update BIOS on the same computer. I enable USB debugging and start flash process, it's failed and android die. Now i can only get DnX.
[Teclast X98 Air 3G] tecknight:
You said it failed to see the tablet to flash the BIOS, right ?

Everything that you are saying points to a driver issue, the flash stops at 12%, BIOS flasher (adb) not seeing your tablet.

Is there any way to recreate Android partitions from Windows? I deleted Windows recovery one and Android does not boot.

I have already win10 and I woudn't like to re-install it.

[Teclast X98 Air 3G] tecknight:
You could create the partitions from Windows, but there is no point.

What you need to do is reflash your android with partitioning from DnX using MFT.

It will work even if you blew away your droidboot partition, because MFT will send a droidboot image to your device and it will load it into memory. You can then re-install Windows 10
[Teclast X98 Air 3G] theYuuhi:
You are absolutely right. A few things bother me:

1) Adb worked fine, since i been able to flash X98 Air 3G 4.4.4(C5Jx) mirek190_v4.2 on the same computer

2) Android failed after unsuccessful bios flash

3) MFT says REBOOT, so fastboot command is sent, am i right?
[Teclast X98 Air 3G] tecknight:
Well, when the BIOS flashing script ran adb, it didn't see your tablet.

So there was no unsuccessful BIOS flash.. The flasher script wasn't able to even see your tablet.

Hence, nothing was executed on the tablet from the FLASH script.

So whatever happened to your android, it had nothing to do with your failure to flash BIOS.

How did you flash Mirek's ROM ? I suspect you used his script, which uses fastboot to flash.

It is possible for the fastboot drivers to work and the adb drivers not to work.

Non-functional adb drivers would cause the BIOS flashing script to not see the tablet and MFT to not be able to kick the tablet into fastboot mode.

It's a possibility anyway. In any event, at this point you MUST have working adb drivers to recover your tablet.

There is no other way

Actually, MFT sends the droidboot image to the tablet in DnX mode. If your SoC drivers are installed properly, your tablet will load the droidboot image even without a working droidboot partition. The droidboot in memory can then restore the droidboot partition along with the others
[Teclast X98 Air 3G] theYuuhi:
Mirek's ROM was flashed following: http://xdaforums.com/showpost.php?p=61852850&postcount=10160

Thank you anyway! I'll reinstall windows and make sure adb works fine.
[Teclast X98 Air 3G] jsager33:
I don't know if this is an issue anymore, however, make sure there are no spaces in the folder names within the path that leads to where the bios flash script is stored. This can prevent proper execution of the script.
[Teclast X98 Air 3G] tecknight:
So MFT worked then, but doesn't work now. Very strange. It could be a cable issue, maybe?

Good luck to you, in any event..

---------- Post added at 03:47 PM ---------- Previous post was at 03:42 PM ----------

That is a good point, but in his case the adb devices command was not showing his tablet, which means basically either a cabling/hardware issue or an adb driver software issue

Can a teclast air C8J7 3G owner check the bios version by using AIDA64 CPUID software?

Is it like the one on this screenshoot below (this is true-dualboot model):
[Teclast X98 Air 3G] supercowz:
need to re-check but i saw on the bios 5.6.5 C8J7 android version ..
[Teclast X98 Air 3G] SUMMERBREEZE:
then all C8J7 owners will get dual boot sooner and later or at least the WIN BIOS to FLASH WINDOWS 8.1 after..
[Teclast X98 Air 3G] USDan:
This is a bad idea, as has been mentioned multiple times. With the likelihood that the (soon to be available) dual-boot version's BIOS is compatible with C8J7, if you can't risk losing the device, just wait the (at most) week or two.

Anyone who did this should learn how to use an SPI EEPROM programmer first, with a good chance they'll need to use it to unbrick their device.

Dual Boot on Tiny Deals

Did you notice that on Tinydeals an official dual boot version is now offered beside an Android and a windows version? Must be quite new, I check the page often. Still waiting for my on 11.11.14 ordered android version. Hoping to get dual boot enabled some time later.

Dual boot is offered for presell here:

http://www.tinydeal.com/de/teclast-x98-air-3g-97-android-44-win81-z3736f-tablet-phone-p-141878.html

They claim to start shipping on December, 20th.

PS. I read the whole thread carefully, but my English is not that good. There is no working TWRP recovery so far, right?
[Teclast X98 Air 3G] ImJamIN:
Excuse me. I'm not English.

We can see a functional dual boot on a c8j7 that it has a 5.6.5 bios.

So I have thought that if your c8j7 android version has already this bios version, isn't it possible that you have dual boot already active?

Or will be a mod version of 5.6.5 bios for dual boot?
[Teclast X98 Air 3G] supercowz:
no, no dual boot, i have uefi 64bit ... on my C8J7 android version
[Teclast X98 Air 3G] ImJamIN:

mirek190_rom_v4.2 - android 4.4.4 (air 2 HG5N) inverted camera image

Hi, Big thanks to mirek190 for supporting Air II users. I've had a search in this forum and I can't find an answer so I thought I'd ask. I installed mireks' v4.2 rom for air 2 with an android only clean install. I am also running bios 2.02. The issue I have is that the camera image is inverted on my HG5N air ii.

He goes out of his way to help people, he knows his stuff very well.

In short, he is a GREAT asset to this forum. Anyone suggesting otherwise is definitely not seeing the big picture.

And I agree with him. I think we do a lot more harm by jumping all over a newbie for simply asking the question he has been trying to find the answer to. Personally, I would rather expend the effort to answer a question that has been asked here before, then to have someone that came here looking for help to not get that help and feel like they can't ask any questions w/o getting jumped upon.

This is what I recommend, given your X98's current state (No Android and apparently no droidboot partition)

1. Uninstall MFT from your PC

2. Install and Configure MFT on your Windows PC <- Click for tutorial

This procedure kills three birds with one stone.

It insures your MFT is installed and set up correctly

It insures your SoC drivers are installed properly

It insures your adb drivers are installed properly

3. Flash a Android ROM to your X98, leaving Windows untouched<- Click for tutorial

and this procedure will restore an Android, droidboot and recovery image to your tablet.

Choose whichever Android ROM you like. You will need to choose the Flash with Partitioning xml file

4. Update the BIOS on your X98 to the latest dual boot version (2.02) <- Click for tutorial

and this will give you the dual booot BIOS once the adb drivers are working

5. Install Windows on your X98

---------- Post added at 11:57 PM ---------- Previous post was at 11:07 PM ----------

mnitstanley,

The X98's integrated wifi chip apparently does not have it's own non-volatile memory on board to store its own MAC address or Bluetooth address for that matter, so the task is relegated to the respective android services.

I am unsure how they obtain a suitable address, but my address is not the same as yours.

1. Install and Configure MFT on a Windows PC

This will install all needed drivers and the Manufacturing Flash Tool to a Windows PC.

Kindly post your MFT log.

BTW, the problem you describe (freezes at 10% in MFT) is almost always caused by incorrectly configured MFT or SoC drivers not installed properly or at all. That is why I STILL advise you to do this:

0. Uninstall MFT from your Windows PC.

1. Install and Configure MFT on a Windows PC

If you follow these steps, you will install all needed drivers and Manufacturing Flash Tool to a Windows PC.

You will then use MFT on the PC (Step 2 below) to re-flash an Android image to your X98 device.

2. Flash a Android ROM to your X98

The only change you will make when you flash your device, is you will need to Select the:
