For C6J6 and C8J7 model

You must download dual boot bios from here

Extract the file "dualboot bios tested C6J6 and C8J7.7z

If you are in android just copy dual bios folder in to the device, then open ifwiupdate and then tap to browser and select the file "X98Air3GDuala.bin'' inside the extraction folder after tap to update (be carefull, you must have enough charge)

After this you must install android ROM again. so grab X98 Air 3G (C8J7.C6J6) Lite 4Gb or 8GB for DualBoot.zip made by supercowz, https://www.dropbox.com/s/c0kg06aq3...7.C6J6) Lite 4Gb or 8GB for DualBoot.zip?dl=0

then flash with ManufacturingFlashTool

for C6J6 open in ManufacturingFlashTool :

flashC6J6-4GB.xml or flashC6J6-8GB.xml

for C8J7 open in ManufacturingFlashTool :

flashC8J7-4GB.xml or flashC8J7-8GB.xml

this last action dedicate 4 or 8 gb of rom space for Android and you can install windows in 18.5 or22.5 gb free rom space.

Then reinstall Android rom as before (open manufacture flash tools and select flash.xml)

After install android rom you can install windows as before (using bootable windows usb disk and select 18.5 or 22.5gb rom free )

For correct work of devices under windows you must install x98 air 3g windows drivers, dowload it from here

FAQ

Q: I flashed android bios, now I can not get in to droidboot mode by pressing VOL- + POWER. The tablet always gets into shell command interface. I can only get to DnX mode by pressing VOL+ , VOL- and POWER. Any solutions?

A: Follow this steps valid for C6J6 and C8J7 model :

Just open manufacture tools,then open file menu and go to the settings.

Put this value to SoC Devices: VID: 8087 PID:0A65

Put this value to Androird Device: VID: 8087 PID: 09EF

Click on apply and then on ok.

Disconnect the USB cable from the tablet and turn off your tablet (important)

Then in Intel Manufacturing Tool and go to the menu File -> Open. There, choose the folder of X98 Air 3G (C8J7.C6J6) lite 4Gb or 8GB and choice "flash.xml" for your device 4Gb or 8GB and open it.

Keep pressed VOL +, VOL- and POWER button until the tablet go to the dnx mode

Connect the USB cable and Intel Manufacturing Tool begins the process of flashing Android ROM.

Wait until the process is complete.

Disconnect the tablet from the USB and and turn off your tablet .

Connect the usb keyboard to the tablet and turn on your tablet, you could get shell command error again

Just type exit and you see the tablet go to the android version

When go to the android you must change your bios with ifwiupdate and you can flash dualboot bios or new android bios from first post
[Teclast X98 Air 3G] codezion:
Very well done keepfishes. Thanks for taking time to put together the guide along with everyone else who are taking time to answer all questions.
[Teclast X98 Air 3G] keepfishes:
Whoa a whole lot of info here... I'll organise it and add it into the tutorial, then add some screenshots and it should be good.
[Teclast X98 Air 3G] supercowz:
you rock dude :) thanks you ...

im not so crazy abt write tutorial with my poor english..... and i made so bad video quality, lol ... im more in tweaking stuff at my low level :)
[Teclast X98 Air 3G] keepfishes:
Haha thank YOU, not me. :) We need more people like you who can tweak stuff. Busy editing the post now, and adding the new stuff in.

One thing though, the last time I hosted on Dropbox and had high traffic, the file got blocked, so I don't know how long the Dropbox link for the ROM will last haha. :laugh:
[Teclast X98 Air 3G] supercowz:
thank you i try to do my best, and share ...

yeah i ask frontier to host my file :)

anyway im arround, we can fix that quick :)

ps : still need c6j7 4.4.4 rom or at least flash.xml, then i will support it in futur, hope to try soon duaboot on c6j7 :)
[Teclast X98 Air 3G] SUMMERBREEZE:
guys we can also use http://d-h.st/ as mirror for each file :good:
[Teclast X98 Air 3G] HDtracer:
A quick question, which operating system recognises the external SD card with dual boot. Windows or android?
[Teclast X98 Air 3G] supercowz:
i format to ntfs so i can install software under win8.1 on D: my sdcard .....then install paragon ntfs in android, i mean my own choice

but maybe split sdcard with half ntfs and the rest on ext4 so both system will be happy

i am wrong ?
[Teclast X98 Air 3G] HDtracer:
Ah ok so if you format sd card with 2 partitions 1 as ext4 and 1 as ntfs they will both use the card.

I was thinking about doing the dual boot thing (dont really need it, but its there to play with now haha) , but have 20gb of music and movies on my sd card and was wondering if it was Android or Windows that would use it.
[Teclast X98 Air 3G] supercowz:
u can keep it in fat32 i guess both will see it and use it, for normal day use like video .. try dude, no worry :)

i should do that too.. less trouble, but i hate fat32 restriction ..

u know loosing 4GB on windows but enjoy dualboot, for me ist must ... your choice :) definitly my choice
[Teclast X98 Air 3G] namth56:
Both for me
[Teclast X98 Air 3G] supercowz:
yep fat32 ... nothing to do, work out of the box for everyday use :)

[Teclast X98 Air 3G] BoORDeL:
You should change this:

Dual boot BIOS benefits:

Fixes 60Hz refresh rate

Into

Dual boot BIOS benefits:

Fixes 60Hz refresh rate for WINDOWS 32 BIT SYSTEM

Because if you plan to use android only, uefi 64bit bios (the former one) isn't affect with that bug.
[Teclast X98 Air 3G] keepfishes:
Yes sir, changes made
[Teclast X98 Air 3G] BoORDeL:
TNX m8

I would suggest you to use frontier share.

Just one share for all files.

What about?

EDIT: and it would be great if we could replicate that share to another system like mega o Google Drive.

Better to redound important files.
[Teclast X98 Air 3G] supercowz:
yep sure :good::o
[Teclast X98 Air 3G] BoORDeL:

[Teclast X98 Air 3G] supercowz:
Nice

I hope deserve nice credit

Spend lot of time on the project...

Still need C6J7 rom or flash.xml to support it too

Ps : not crazy about keyboard inside the lite rom..
[Teclast X98 Air 3G] keepfishes:
You've worked hard my friend, cheers to you :highfive:
[Teclast X98 Air 3G] BoORDeL:
Just one more tip for FRONTIER:

mate you should reorganize your share.

Use more subfolders to distinguish the use the files are intended to.

I'd like to reorganize it using this thread model:

ANDROID DEVELOPMENT

WINDOWS DEVELOPMENT

DUAL BOOT DEVELOPMENT

and if in need more subfolder to differentiate procedures by teclast model number (IE: c6j6, c8j7 etc..)

[Teclast X98 Air 3G] supercowz:
oh ... i see, coool.... no time to decrypt chinese, maybe i should, but i dont read chinese, and bing translator is boring....

i did miss dualboot bios lol .... at that time ....

my tablet is charging well and fast under win8.1 when im using it

my recommandation is us a good quality short cable (i use 5cm usb cable)

the official teclast cable is short and good quality... give good result too, but if u use crapy quality cable.... and long too hum not good... your tablet will not charge under win8 or really really slow ...

we are talking about 2.5A we need good short cable, specially under win8

anyway i know some model have battery problem, but different story

should add this to the faq or recommandation

good night

[Teclast X98 Air 3G] keepfishes:
Yeah around the same time too. The charger block does get hot too I agree.

It seems to charge slower with the tablet turned off.

Hello....

thanks to supercowz, mohamad_skiller, ro11er, petruccig and Frontier. :good::good::good::good:

After I made a mistake and like to install the Dualbios by Stock Rom and a copied Version from IFwiUpdater I had luck and everything goes well. Special thanks to supercowz for that.. :good:

Very imprtant is realy to have the Android Version with IFwi Updater in it. Dont copy from other Androidversion like me.

You wil brick your tablet. Then you can install by IFWI Updater the dualbios without trouble. Then with the manufactoring Flash tool

the Android Lite Rom and in the end windows 8.1 by making a booting stick with rufus tool.

Now a special question. Is it possible to install Ubuntu 14.04 too on this tablet beside windows 8.1 ?

Means. One Partition Android with maybe 4 GB, Windows with 15 GB and Ubuntu the rest ?

Maybe install Ubuntu after windows and you become a grub2 boot manager screen ?

Greetings... and thanks again at this team here... (and the chinese team)

[Teclast X98 Air 3G] PWMx:
About battery capacity and charging

The average lithium cell voltage is ~3.8V. (Full charge is 4.2V and typical discharge cut-off ~3V.)

USB chargers deliver 5V and 2A.

So two hours would charge 2h*2A*5V/3.8V=5.26Ah (in ideal case - in practice quite a bit less).

This would be practically half the capacity of specified 8.5Ah.

(This device seems to have two cells in parallel. If someone claims half the operating and charge times then I would suspect one cell with open contact...

...Or even more probably some SW glitch or other measurement error.)

It is also important to note that the tablet can consume near 10W (if not even more) at maximum display brightness and high activity.

In this case the battery will not be charged at all (or could even be discharged) due to USB current limitation.

Thus the charge time should only be measured with the tablet off and with a standard USB charger (2.2A 5.0V).
[Teclast X98 Air 3G] jcespi2005:
You can download the V1.0 firmware from

http://dl.vmall.com/c0jprfzibk

Hope works for you, here at work can't connect...
[Teclast X98 Air 3G] ambrosio5:
Excellent and very analytical guide. But please notice that if you have Android 4.2.2 on the tablet (c6j6) and with bios 1.10 if you download and use UpdateIFWI with "X98Air3GDuala.bin'' (or any other BIOS) it keeps saying "Upgrading, this may take up a few minutes..." and actually does nothing! I've tried it 2-3 times and luckily it didn't change the current BIOS.

I was terrified that I was getting a brick! :eek::eek: This also happened to other guys here!

So I think you must specify that perhaps “UpdateIFWI.apk” only works with 4.4.4 or something.

Thanks again for your guide!

Sorry for my English - I use a translator.

Unfortunately, I was able to damage your tablet.

When you try to install Windows (using x98 toolbox) tablet crashed.

Now when starting displayed: blkC: BlockDevice - Alias (null).

I also have a possible entry into the BIOS.

Unfortunately, you can not re-install android Manufactured using Flash Tool.

On the tablet displays the message "waiting for fastboot mode ..." and nothing further happens.

I tried to reinstall the drivers but it did not work.

Hi again, could you please specify which version from the above link you are using?

Since I'm also a member on the teclast forum I only rely on the poor translation from Bing or Google.

So the above link http://bbs.teclast.com/thread-259131-1-1.html sends you to http://bbs.teclast.com/thread-258279-1-1.html and you can download 2 proper versions of 8.1 pro:

2. Appropriate to streamline the rapid version download link: http://pan.baidu.com/s/1pJFjq5P Password: wy2q

Hello,

I'm after a program that will let me quickly knock up a list of things to buy when i go shopping. It should have a list of items that I regularly buy thats customisable, then when I run out of them I can tick them off. When i go to the shops it should be able to bring up a list of everything I need to buy (and not the things I don't), with a tick box that removes each when its in the trolley.

Does that make sense? Does something like that exist? Does someone want to write it for me?

Cheers.

[HTC One SV] raisinette:
Hi!

I have a serious problem here. I offered to try and fix a friend's HTC One SV (4.2.2 Jelly bean). His battery died a few days ago, everything was working fine before that. He charged the phone and tried turning it on, but now it gets stuck on the HTC One welcome screen. (I've added a photo of the bootloader screen as well) The phone is not rooted. I've tried everything - clearing cache, recovery mode, factory reset.. Nothing helps. While researching for solutions, I stumbled upon a post where they said that if it were rooted, a custom recovery or RUU would be possible.

Since I am a bit of a newbie to rooting and hacking in general, then I'd like to ask if it's possible to root the damn thing now that it's not turning itself on properly and unlock the bootloader so I could flash a new ROM for example. Will it do any harm? Do you have any suggestions?

P.S.

Taking it back to the shop is an option and I am aware that warranty will void once it's unlocked. Despite this, we're willing to give it a try.

Thanks in advance.
[HTC One SV] old.splatterhand:
I'm a bit confused, about that "Security Warning" on the picture. Not normal at all!

But if you really want to root, unlock your bootloader at htcdev.com.

Follow the steps, they provide a guide on their website, how to unlock.
[HTC One SV] raisinette:
Turned the phone on and went to the bootloader, the security warning is gone. That's good, I assume? What about this ***tampered*** part?
[HTC One SV] old.splatterhand:
It seems the phone was unlocked/S-off already, and the one who locked it back to stock forgot to reset the Tampered flag.
[HTC One SV] raisinette:
That can't be. He is the first owner and hasn't touched it in any way.
[HTC One SV] old.splatterhand:
Tampered appears only after unlocking the bootloader.

Maybe a refurbished device!?!
[HTC One SV] raisinette:
Ah, yes! I completely forgot about that. He had its power button repaired a few months, perhaps the tech guys did something with it.

Will this change anything?
[HTC One SV] old.splatterhand:
No, not really. You need to unlock at htcdev.com.

Thats your first step.
[HTC One SV] raisinette:
I've been trying to do that for the past 2 days, but I'm stuck at step 5 - when I type in cmd ''fastboot oem get_identifier_token'', it says ''fastboot is not recognized as an interal or external command, operable program or batch file''. When I clicked on the fastboot.exe, it said something like adbwinapi.dll is missing. Downloaded that, the error was gone.

I've googled for solutions and so far none of them have worked. What could be wrong?
[HTC One SV] old.splatterhand:
Do you have htc drivers installed on your pc?
[HTC One SV] raisinette:
I have HTC Sync Manager. The drivers should come along with that, or not?

EDIT: Something odd happened - the phone started bootlooping, so I did a factory reset and then a red text appeared saying ''this build is for development purposes only.... etc''. I have not started unlocking the phone, it was simply connected to the usb while the bootloader was open. After the hard reset it does not bootloop anymore, but it is still stuck on the welcome screen. Thought it may be important.
[HTC One SV] old.splatterhand:
I don't know, what happened to your device. But you need to solve this fastboot issue on your pc to proceed.

Also check, if the bootloader still is locked.
[HTC One SV] raisinette:
I finally got my bootloader unlocked - it turns out Windows 8.1 was the problem. I couldn't manually install any drivers, so I refreshed my Windows back to 8.0, that helped.

Now, I'd like to root it and flash a custom rom to see if it helps me get out of the stuck HTC screen, but every rooting guide requires USB debugging to be enabled. How can I do that if I can't access the settings, because the phone won't turn on? :D
[HTC One SV] old.splatterhand:
You can boot into bootloader, do that. Plug your phone to the pc and make sure your phone is in fastboot (usb) mode, not in hboot mode.

Download this three things:

- http://download.chainfire.eu/supersu

(copy to sdcard of your phone)

- the recovery from first post of this thread http://xdaforums.com/showthread.php?p=41456540#post41456540

(copy to the folder on your pc where your fastboot.exe is)

this stock rom for your variant (or another rom for your variant http://xdaforums.com/showthread.php?t=2512742

(copy to sdcard of your phone)

Follow the "How to" in recovery thread to flash recovery, then follow the "How to" in the rom thread to flash the rom from recovery and at last step flash supersu.zip from recovery.
[HTC One SV] raisinette:
Thanks for taking the time to help, your instructions and advice has been indescribably useful :)

The phone is working fine again and it's all thanks to you.
[HTC One SV] old.splatterhand:
Cool, you're welcome :cool: :laugh:
