Hi. Thank you for the quick answer, friend. I am using a powered USB from Trust (http://www.trust.com/pt/product/15140-pyramid-7-port-usb-2-0-hub), and tried with all ports, but no one worked. I see my 16GB flash drive on the 2.02 BIOS screen, it appears on the boot order list. Both Android and Windows show it on their files programs. I'm using GPT for UEFI partition type with a FAT32 format with Rufus 2.8 (latest version) and downloaded GParted-live-0.26.0-2-i686.iso from their site. But if it works, I'm gonna use it with PhoenixOS and ChromeOS via live USB either. Do you have any clue on this? Thanks again!
[Teclast X98 Air 3G] Mikha777:
I don't use Android myself only Windows 10 but your problem is that the X98 is using a UEFI bios so not all ISO can be installed on the X98 to boot from USB drive. Look here https://www.reddit.com/r/PhoenixOS/comments/426728/easy_uefi_install_for_p for Pheonix OS it should be the same problem for Chrome OS ;)

If you google to find solution for problems related to installing those OS on UEFI tablet/computers use keyword UEFI in your search :angel:

Front Camera not working

Hi guys

I upgraded my C9J6 to bios 2.02 dual boot and I am facing a problem in windows now. The front camera is not working anymore in windows (The back camera works fine) I get the STATUS_DEVICE_POWER_FAILURE Code 10 error. I tried looking at the hardware it does not seem to have any visual issues and I did not mess with the camera to break some wire I think. Also in windows i have the "X98_Air_3g_android_5.0_mirek190_v7.0-ultra-light" rom installed and when I turn on the camera it does not open i get an error saying camera app stopped working. Now I am not sure if the problem is hardware or software. I have seen some posts on this thread saying it is a software problem but no solution. Can someone please help me fix this issue?

Thank you

Hopefully you know the solution for windows [MENTION=3986785]Mikha777[/MENTION]
[Teclast X98 Air 3G] Mikha777:
Sadly at this point there is no real fix, I was supposed to do one but I have not enough time to complete the fix. It's caused by a bad implementation of Firmware 2.02 and higher so there is nothing we can do for it. It only affect the first batch of X98, the latest don't have the problem. :(

One work around would be to replace the front camera module with a newer camera module OV5648. But those module are not ez to find. :cowboy:

[Teclast X98 Air 3G] rafabrasil85:
Thank you sooo much for your help! This link was very useful and I finally got boot from pen drive feature to work. I used a 64 bit version of ChromeOS called CloudReady and it worked, although it does not support X98 drivers and it's not usable then. Now that I see it works, I will try to find a PhoenixOS ISO file which is UEFI compatible. Thank you very very much!

Could you help me with one more thing? I've installed version 1.0 of RemixOS on internal memory but I really want version 1.5 which is based on Lollipop and I can't find it anywhere on Internet. OTA update on settings doesn't work at all, and also offline update using their specific app and 1.5 file is not working. I've tried many things without success like posting on specific threads here on XDA (got no answer), searching on Jide (Remix developer) and Teclast forums, and many keyword combinations on Google. I don't want to give up on this because I saw on Teclast forums (translating from Chinese) that they have released this version, but the links don't work anymore... Could you suggest anything to help me? Any insight is welcome! I think it's the last thing I want to change on this tablet. Thanks again!! =)

I was also thinking of replacing the module since the front camera does not have good quality either. Can I replace the camera module with any OV model or specifically OV5648?

And one more thing in android the camera does not work at all is there a way to fix this issue? Is that problem due to the rom or also a bios issue?
[Teclast X98 Air 3G] Mikha777:
You must use the same exact module cause it's programmed in the firmware and if you don't the camera will not be recognized :cowboy:

For Android I really don't know since I don't use Android but only Windows. But from my theoretic knowledge the back camera

should

work fine. :silly:

I did not forget you, it's just that I did not find the time even for me, like I said when I will open my X98 to fix the camera I will read the value of the Res/cap and send it to you. Maybe somebody else in meantime can will open his X98 and could be able to give you the value. :cowboy:

Could you take the value [MENTION=2120608]Kryogen[/MENTION] of the capacitors/Resistance around the Firmware/bios on the X98 from the broken one you have ?

Could you check them with a glass magnifier glass to read the numbers on them ? :angel:

I'm pretty sure they are resistors or capacitors if they are resistor they will have a number on them but if they are ceramic capacitor they could have nothing marked on them since they are too tiny but some have a numbers.

[MENTION=7418656]Madhavnarayan112[/MENTION] is a little desperate to have those values, I'm pretty sure they are all the same values

hey guys,

i was running windows only for a while on my c5j6 and i now want to go back to dual boot. I installed the dual boot bios back than but i´m not up to date so may be someone can point me in the right direction.

My problem right now is that i can´t seem to boot into fast boot. When i try it shows this screen

Any guidance? :D Maybe i deleted a partition or something idk. I can enter bios and boot into windows just fine.

i somehow fixed it... not sure how but it suddenly booted into fastboot

You can usually buy them from Chinese distributors, google the number of the part you need you should find some distributor. ;)

Thanks for your help. My tablet is still on bootloop, showing these lines

as soon as I plug it on charge. I think bootloop prevents battery to recharge itself. I've already let it plugged for one, two and more hours. When I try to turn it on, nothing happens. Don't know what to do, since I've already unplugged and replugged white and red battery wires. I've searched a lot on Google and YouTube, but for now nothing works. Hope someone saves my Teclast!
[Teclast X98 Air 3G] denis1304:
maybe you can charge your battery outside and then plug it back in the tablet? don't know how or what charger to use...
[Teclast X98 Air 3G] Madhavnarayan112:
Just donot try to charge the battery out side ,it can damage your battery , just lisint to me ,and follow my path if you want your teclast back

First use battery red and either white or black wire just as a normal battery + , - terminal and connect it to some small device like led or dc motor any thing which can consume battery power so it became completley empty., after that when you will find your battery fully empty , charge your teclast with charger of 5V <1.5A for 12hour and in this period donot try to power on your tablet.this is the obly process to get back your teclast.and if you experminet other thing on device than its all your risk.just follow my steps.

[Teclast X98 Air 3G] justason:
Not exactly, the flash chip we have, at least on C6J6 is 25Q64FW, and according to datasheet,

the operating voltage is 1.65-1.95V

Using 5V-3.3V programmers might burn the flash down.

The chip could became not programmable.

C6J7 Drivers and Bios dump

All,

So as promised here are the (complete) drivers and the Bios of my Teclast X98 Air 3G. I hope it will help you install Windows properly on the C6J6.

Camera is ok and refresh is 60Hz on mine, so I think the 2 main problems are solved. Windows is quite responsive, no apparent problems so far after a couple of hours of usage.

Wel it seems there is something wrong with the 4.4.4 recovery or boot menu.

Headset does work

The generic mic gain fix is enough. After it you can make phone calls.

Integrated hands free works when you activate the speaker button in call UI.

(Default routing is to earpiece - which is not present in this tablet.)

Also headset microphone works ... when you have compatible one, that is.

There are two major 3.5mm plug pin-outs : OMTP and AHJ/NAHJ/UHJ. This tablet has OMTP standard pin-out.

(OMPT stands for Open Mobile Terminal Platform - It's a standard group. And its 3.5mm pin-out was used first. And is still required in China etc.

Then Apple made their own pin-out just to be incompatible with everything else by swapping mic and gound lines. A in the AHJ.

Later this was pushed to north american operators and then also become requirement for device manufacturers.

Hence A was thought to mean "America". However south america didn't follow this spec. NA = "North-America" ...

Some operators thought it should be "Universal" headset jack :silly: What a mess !)

And 3.5mm stereo headphones will work equally with both. (Ground and mic lines are then connected together.)

BTW - It would nice to have some wiki where all relevant information would be collected and updated. Over hundred pages is a bit too much to search from.

I had Mirek's Lolipop v7 but couldn't get rid of this battery meter problem. I clean flashed the Kitkat v7 rom via his flash tool and had no battery problems but after awhile my tablet keeps resetting/rebooting itself everytime i put it in standby. I did a new flash but same problem.

Today i tried flashing it via MFT, keeps resetting/bebooting itself after i put it to standby.

After rom installation the "SuperSU" and "BusyBox" need to update via Playstore and some updates inside the SuperSU App. Maybe thats the problem?
