no Root and after Xposed = BOOTLOOP

mirek190_rom_v4.2 - android 4.4.4

Hi Mirek...

I have now your version v4.2 installed on my device (C8J6) with the special BOOT.IMG. (fresh install (wipe))

It does not work your ROOT function (SUPERSU is indeed installed but without function)

After rooting with the toolbox and installed Xposed the device starts only in a BOOTLOOP.

Do you have a solution idea.

BEST WISHES...:crying:
[Teclast X98 Air 3G] mirek190:
Have you used my special boot.img ?

From my google drive ?

You remember after clean flash device will restart itself twice .
[Teclast X98 Air 3G] articsilverfox:
Yes I updated to bios 2.02

I followed the main guide for updating roms from TecKnight's Teclast Tutorials series guide index.

Its in the speedtest info, its the C5J6, its the 64GB version, yes with dual OS.

I was confident in it working my only fear was maybe my micro USB cable would be dodgey and cause a failure in the update but nothing went wrong. The tablet did reboot at least once on its very first power up after updating which I wondered was deliberate or not but it all worked fine in the end.

I managed to get a better speed test result as well after the my last post.

Hi panie Mirku,

After flash c9j6 4.4.2 via with Intel manufacturing tool - wipe- system only, Tablets boots to Android only, not to windows anymore.

If I understood correct I have to flash bios also via your new tool. Then will have dual boot again.

For that I have to save windows key saved in bios before, correct?

and inject it to new bios afterwards?

...and i have used your new special boot img,,,

My bios is still stock one.

sorry found vol+ and power on works...

[Teclast X98 Air 3G] chrissss91:
Yes but to save Windows key stored in BIOS you need to launch the tool from

Windows on the tablet :(

IIRC there is a command line to boot to Windows from fastboot or something like that. TechKnight can maybe help you.
[Teclast X98 Air 3G] Hendrickson:
Yes, but others have been able to use it and inject Windows keys into the bios and apparently change the boot up image logo file. I think it has to be run from a Teclast tablet or the bios needs to be placed in the dir. Really needs someone that understands Chinese.

This tool will write your oem Slic bios key to a text file: http://techtablets.com/download/Windows CD Key tools/OEM SLIC Bios Windows key reader.7z

By the way, Teclast have an announcement coming 10th of August. A new 9.7" tablet with a Core M and maybe Cherry Trail :)

Bios Fix

Yes, i think i need a old bios as well, maybe 1.05. I have a c5j6 model of teclast that could enter sleep mode and hibernate (i.e bios that support sleep state s3 and s4) but then i flashed a new bios 2.02 which doesnt support s3. Sleep doesnt show up any longer. I have tried all windows tweaking to bring back sleep, but it seems only solution is through the bios. Please i need help.

Hi.

I bought the X98 air 3G C5J6 64gb dual boot and I want to install the fresh 4.4.4 kit kat of mirek190 v4.2.

I don't know what's the sequence of the installation on win 7.

I need to install the device driver first?

Then I run some kind of tool? What should I press? I don't want to lose the dual boot feature

Is there a detailed guide on how to change the stock rom?

I would appreciate it if mirek190 could give me a guide.

Best Regards,

Akis

Well I think Teclast will have 2-3 new tablets to announce on the 10th. One a top of the line Core M retina tablet, to compete with the Onda v919 Core M. Then a 2GB, Atom X5 Z8300 or hopefully Z8500, 32GB-64GB eMMC 9.7" retina X98 air upgrade. And maybe an eight inch X80 with a Cherry Trail and 1920 x 1200 to better the Chuwi Hi8.

All Windows 10 andAndroid 5 dual boots :D
[Teclast X98 Air 3G] BloodRose:
Sorry if this has been answered already but this thread is massive.

I have an Onda v102w which has exactly the same Intel chipset as this tablet but a slightly lower resolution screen (1080p). It just arrived last week with Windows 8.1 pre-installed on it. Could I also dual boot it into Android?

I'm not really that fussed about removing the recovery partition and creating a new one of my own since the default build was all in Chinese. I actually had to navigate around it by guessing what some of the characters meant based on their reading in Japanese and then I removed all of the Chinese and just installed the English and Japanese MUI packs.

Thanks. :)
[Teclast X98 Air 3G] majkel_94:
Could you make this tutorial with more details?

I am fighting with my touch driver, I have C6J6 and Win8.1 and use the first 3driver combo to work touch,camera and screen orientation ok.

But I also have to use the startup script to reinstall driver on startup to prevent inverted touch after rebooting from Android but sometimes in fails and give me BSOD.

I want to perform a clean install of Win10 but I don't know which drivers will be good?
[Teclast X98 Air 3G] tecknight:
Bloodrose,

Does Onda sell a dual boot model v102w ? If they do not, then there isn't a dual boot BIOS available. That would make it a virtual impossibility to set up that tablet for dual boot. Does Onda sell an Android version of the v102w ? If they do not, that would be major issue #2. The two tablets may share a common SoC, but they are far from having identical secondary chipsets, bus addressing, etc. You couldn't just boot android for the X98 on the Onda or flash the Onda with the X98 dual boot BIOS.

Sorry to be the bearer of bad news. How does Windows run on the Onda ?

TOUCH FIX TUTORIAL C6J6 WINDOWS

I have my graphic drivers updated up to latest 25-may-2015 release. Cameras are inverted but I prefer having the latest driver from Intel which could improve tablet performance...

1. Download this pack from my dropbox https://dl.dropboxusercontent.com/u/30899299/Teclast x98 c6j6 touch fix.rar

2. Attach a mouse and keyboard to the tablet. Unstall goodix drivers and aso delete the files.

3. Install drivers from the .rar package provided. Then, copy the file "touchsetting.gt" to c:/windows/inf and overwrite the one existent (with admin privileges...).

4. Reboot the tablet. If the touch is fine, continue to step 5. If it's inverted, open touchsetting.gt and change this:

X2X=1

Y2Y=1

X2Y=0

for this:

X2X=0

Y2Y=0

X2Y=0

Use Notepad++ to be able to overwrite the file and preserve .gt extension. If you're using the default note app from windows, save the file anywhere else, then delete the last ".txt", and when the file is ".gt" overwrite the one in c:/windows/inf.

Now you've corrected the touchsettings.gt, check if it works: Go to device manager, select goodix touch, disable it, and enable it again. Check if the touch orientation is fine. If so, go to step 5. If not, try to change X2X, Y2Y and X2Y parameters playing with 0 and 1, but the most common is 0,0,0 or 1,1,0... Also check if "SendCFG=1 " at the beggining of the file, without ";" first in that line.

5. Now you've the touch orientation working fine, run Touch 8 app and slide the slider all the way left to 10ms and press apply button.

6. Open regedit.exe with admin privileges, and go to

HKEY_CURRENT_USER\Software\Microsoft\Wisp\Touch

Edit "Friction" value from 32 to 0

7. You've finished. Restart Windows and tell me how it goes :D

edit: My only problem are inverted cameras in Windows. I guess it has to be a way to turn them the way they should, but I don't know. Probably changing some parameter in bios programming? Probably it's just a registry value to edit? Please, if someone has been able to solve this issue (while keeping graphic drivers updated) tell us!
[Teclast X98 Air 3G] BloodRose:
No I don't think Onda produce an Android BIOS for it unfortunately but I know a lot of these Chinese tablets are actually identical hardware under the hood so I'm not sure if it would be possible to cross-flash it with the bios from one of those if one of those has an Android variant. Obviously that's a bit risky though. :)

Windows is fine on it, although a particular Windows Update has been failing since I got it last week (I think it's a large definitions update for Windows Defender). I just wanted Android to run the occasional app like Google Books and maybe games like Fallout Shelter. I've tried DuOS but it's limited to only 600MB of system RAM. unfortunately. Thanks for your reply though, at least I know now I suppose.

Incidentally though, I only get 15 fps on this tablet on Dolphin for Windows making it unplayable unfortunately whereas my previous Windows tablet was a Linx 10 and that got around 22-25fps on a Z3735F. It isn't the higher screen resolution that's causing the lower performance either because I've tried knocking that down to as low as 640x480 and it didn't make any difference.

Has anyone downloaded the Windows 10 installation files ahead of tomorrows launch? The system should download them automatically if you have made a reservation through the update app.

My pc apparently has finished downloading the files but nothing is happening on my Teclast. Maybe its a disk space issue since I have only about 4 gigs of free space on my C: drive?

The installation files should be located in C:\$Windows.~BT\

I would also like to point out that apparently you can't install the OS until tomorrow even though your system has downloaded the files.

Leave tablet plugged in for 2full hours (1is ok too) This is normal when battery is fully drained out. Also it drains easyer with older bios. Mostly because older bios wont deep sleep and always ends up drained battery under 24h. New bios will stay standby for days before battery is out.

It will take more than 1-2minutes to charge enough to start. Be patient, leave it and come back. Your tablet will be fine. Because you see the errors its already charging. That message in the screen is charging animation bugging out, it already charges, but slow and drains more when screen is lit.

I still have the problem when I do a Hard-reboot (advanced menu Xposed) under Mireck190 v4.2 with ViperandroidFX that appears but does not disappear automatically, I have to close it myself.

[Teclast X98 Air 3G] tecknight:
Same issue here. My PC has the files already, X98 has none.

I wonder if it's related to the fact that my PC shows this:

Also, my X98 has 16GB+ space available
[Teclast X98 Air 3G] mirek190:
Soft reboot not run init.d or any other rc files because they are already in memory - soft reboot is me like gui restart .

Only full reboot run rc and init.d files.

Viper should close itself after run on boot - maybe you do something while still device load system. If you wait 20 second after gui shows itself them viper4android is starting and closing .

Why - because after restart device viper4android not working until you run it ...that's why I added autostart for this app like that .

If you want you can remove viper4android from init.d but then you have to run it by yourself on each boot.
[Teclast X98 Air 3G] Franckydiam:

the only thing I do after boot is to enter my password to login, and viper4 start and not close

[Teclast X98 Air 3G] mirek190:
Because normally apps start in background - I tried to run viper4android in background but didn't work.

Or remove viper4android from initd if you wish and run app manually on each boot .
