guys i have got Teclast X80H with me. Do you think flashing a custom rom (maybe [MENTION=2198172]mirek190[/MENTION] 's rom) will be compatible or just wont work?

Go to the Intel Graphics settings utility (find it in the tray), choose Power section and disable all energy savings functionality. That will fix the auto-dimming issue.

Hi Guys. I've bricked my C6J7 Air 3G device and that forced me to flash (using the clips and a programmer) BIOS taken from Air II device. I had a chance to check the BIOS and it always showed GPS as disabled (even on original BIOS). I've tried to manually add a device/driver and guess what. It simply works.

Go to Device Manager and from the context menu on root node (usually showing the computer name) choose "Add legacy hardware" - sorry I've got localized Windows and don't see the exact English wording. Simply choose click the second (last) item from the context menu.

Click Next on the welcome screen

Choose "Choose from the list" and click Next

Choose "Sensors" and click Next

Choose "Broadcom GNSS 47521 Geolocation Sensor" and click Next

Click Next

And that's it. The device will appear in the device list and location service start to work immediately. Try "Maps" or "Here Maps" to test.
[Teclast X98 Air 3G] majkel_94:
So we can flash Air II dual boot bios and have working 3G & GPS + no battery drain? :D
[Teclast X98 Air 3G] the_jako:
but there is no Air II dual boot, isnt it?
[Teclast X98 Air 3G] Flash2light:
Thank you for this :) Bios installed and working.

[Teclast X98 Air 3G] grigoris_a:

I'm having normal battery drain with Wi-fi and Bluetooth on. It's definitely not 30% during the night. My guess (I'm still observing) is 6-7% in 8 hours. But I'm not sure, I need more time to make statements :)
[Teclast X98 Air 3G] mnitstanley:
Thanks for confirming it.

Do you have the battery drain issue in Windows with new BIOS ?

Did you have the GPU problem earlier ? If yes, then did the new BIOS solve it ?

Does the sound work OK ?

Also please check the GPU frequency via terminal.

Run these commands from Terminal Emulator for Android. Download it from playstore.

Hi, I know you have to wait for them from China but look on aliexpress for the tempered glass protectors.

They are about $20 but worth every dollar. The touch feel is fantastic and seem to make the screen more sensitive.
[Teclast X98 Air 3G] ayamgoreng:
so basically ipad screen protector not compatible with x98 ?
[Teclast X98 Air 3G] HDtracer:
They kind of work but the apple one has holes in it and Teclast ones dont. If you can live with it they would be better than the plastic ones from aliexpress.

All of the plastic screen protectors on aliexpress are too soft and scratch really easy.

USB hub and charging at the same time

I got the same hub and the same problem. I tried many different combinations of connection and otg/ charge switch positions. Non worked with the X98 (C9J8). But with my Note 3 it worked perfectly, I could charge and hook up a hard drive and a usb stick at the same time with ease.

Are there any tricks left, or are there different verions of this hub on the market?
[Teclast X98 Air 3G] ambrosio5:
Hi,

On C6J6 everything works exactly as the older dual bios? I mean camera and sound are ok in android? Does the camera still need the same fix in windows?

I mean the only reason for putting this bios is the battery drain issue in windows, correct? :confused::confused:
[Teclast X98 Air 3G] BPM:
this is strange. i can see the usb drive in the bios and can select to boot from it. but it still boots up into windows.
[Teclast X98 Air 3G] grigoris_a:
Camera still needs the fix in windows.Didn't test android because was too busy finding the way to make the modem work.And yes the only reason would be the drain to use this bios(witch I am not sure that it fixes)

If i remember correctly, air II owner's with dual boot confirmed battery drain with windows... So seems all dual boot bios have this problem...
[Teclast X98 Air 3G] the_jako:
Is this correct? I thought that this bios doesnt have battery drain!!

What about the new (1.05) bios???
[Teclast X98 Air 3G] rlego:
as i mentioned, i have well working dual boot (c9j7). I'm ready to flash tab with different partition table. I've found mirek rom for c9j7 (version as mine). Can i use any version of Windows with bing??? I've found X98_Air3G_C6J7_Win81_20141022, and there is an older X98Air_Windows_20140811 on first page in this topic.
[Teclast X98 Air 3G] antony84:
Bios 1.05 (C9J8) is dual boot, and have battery drain.

Bios dual boot of Air II seems have battey drain too.

The only bios without battery drain are orginal C6J7 bios and Air II bios. Both NO dual boot bios, only windows version.

At least, this is what people have reported here, not tested by myself.
[Teclast X98 Air 3G] Graf Schmidt:
You didn't get your teclast yet? :D
[Teclast X98 Air 3G] Flash2light:
1.05 bios bin file is integrated in the key. This key is incorrect. if possible, a copy of the original key. The key can be found in the c: \ windows \ system32 \ config \ Regback and file SOFTWARE.

File in use "system". You need to boot the system windows usb 8.1 installation. Repair -> cmd -> c: \ windows \ system32 \ config \ Regback and ren Regback regold

Now the files are readable in windows.

Now you need MiTec software.

Open SOFTWARE file in this.

Now you can find the original key.

Is there a way to share folder between User 1 and User 2 in Android?
[Teclast X98 Air 3G] dmandic:
I asked similar question some time ago, but nobody answered.

My idea was to boot Acronis Drive Image via USB stick, and make backup of all (or just important) partition on SD card. Acronis has a sector-by-sector option to make backup, so I think I should make exact backup image, regardless of filesystem and position.

I used it a lot to make backups of Windows and Linux partitions, only thing is that I used it on HDD partitions, never used it on SSD disks, so I don't know will it be a problem.

If anybody has some experience on making backups of X98 partitions, please share.

Download the bios files from the guide "from windows to android" and then replace the .bin file with the bios that you want to flash.Open cmd as admin and run the .bat

[Teclast X98 Air 3G] dmandic:
I don't think that backup destination is a problem. You can put it on sufficiently large SD card or you can connect large USB or even USB HDD.

I bought USB on the go hub with three ports and charging option so I think it should work...

Recover some disk space in Windows 8.1

Hey guys.

Back to dualboot - using Mirek's build and Windows 8.1 Enterprise. I wanted to recover hard disk space and I tried deleting the recovery partition but.... It is not there! My installation, not being an OEM one, seems to not create such a partition.

But I had only 3Gb left once I did all the updates... So I was sort of not happy with this. I did some research, and found out that automatically windows will clean up space only after 30 days after the updates, to allow you to uninstall any updates.

So I did the following- cleaned-up the components manually. You can do this by going in an elevated command prompt and run the following commands:

The following command will uninstall all previous versions of components without the scheduled task’s 30-day grace period:

DISM.exe /online /Cleanup-Image /StartComponentCleanup

The following command will remove files needed for uninstallation of service packs. You won’t be able to uninstall any currently installed service packs after running this command:

DISM.exe /online /Cleanup-Image /SPSuperseded

The following command will remove all old versions of every component. You won’t be able to uninstall any currently installed service packs or updates after this completes:

DISM.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase

The latest is what I did, and freed up 3 more Gb. Not perfect, but getting there.

Hope this helps you out!

Hello all,

a pity we still have to wait to enjoy dual boot bios without battery drain. It seems Teclast has stopped developing any option regarding windows freeze after android workaround....maybe we should start contacting them again claiming for that! I will contact them asking it, but it would be nice all of us with freezing problems contact again our vendors in order to put pressure on Teclast!

One question regarding usb hubs with charging capabilities. I have found this hub in aliexppress:

http://www.aliexpress.com/item/Micr...erter-Extender-for-Micro-USB/32262141723.html

Do you think it will charge at the same time you can use usb devices? Normal hubs I have seen doesn't have a usb input to connect a charger...do you think this will work? Which ones have you tested and work already?

Ext4 better for android but won't work be seen by Windows.

2.http://mindbendingpuzzles.blogspot.co.uk/2014/06/android-tip-3-sharing-folder-between.html

The way multiuser works is something like - for user1 /data/media/0 gets mounted as /sdcard - for user2 /data/media/1 gets used as /sdcard.
[Teclast X98 Air 3G] kostas-k:
1) I used free MiniTool Partition and made second SD card partition ext3/ext4 format. The problem I have is that with Link2SD I can't move applications on 2nd partition despite the fact that it's mounted.

2) You can make a Download folder on SD card which you can share between users, I think that's the best solution

I asked Anna Fang the same thing, the answer was that only Dualboot bundles have the 64GB option. I hope, as it's more expensive, to have a better and faster eMMC.
[Teclast X98 Air 3G] jcespi2005:
The option to move app/lib/data to ext4 partition is "link", not move... the "link" option moves app/lib and/or data to second partition, and creates the links so the system thinks it's located on internal.

You can boot from USB in the same way like boot Windows 8.1 Installation from USB - override in BIOS settings.

Charge info

For those interested in some info on the battery and charger under Android

I installed Terminal Shortcut and made a script

echo 'Battery status:'

cat /sys/class/power_supply/dollar_cove_battery/uevent

echo 'Charger status:'

cat /sys/class/power_supply/dollar_cove_charger/uevent

Of course commands can be issued also with any terminal program.

The interesting parameter is POWER_SUPPLY_CURRENT_NOW=928000

Indicating that in this case the tablet is loading with 0.928 Ampere, the net difference between charger input and usage.

Depends a lot on screen brightness, programs running, adapter and usb cable. The teclast and ipad chargers both work ok.

Hi, I did not tried myself, but I think it will not be problem.

I am sorry, do not have a time to try this, but in according http://askubuntu.com/questions/395879/how-to-create-uefi-only-bootable-usb-live-media, it looks you have to use GPT always when booting through UEFI.

There are more informations about running custom OS on baytrail CPUs: http://xdaforums.com/showthread.php?t=2500078

In general our units lacks x64 UEFI, so for running Ubuntu you have to create GPT USB Windows bootable stick and copy files to this stick. You also have to add x86 UEFI to make boot possible.

[Teclast X98 Air 3G] Perfectdevil:
recovery partition is there for you if you want to RESET windows to default if you deleted this partition you will not be able to restore windows system if you mess it up!!!

still if you want to delete it you should delete both OS and re-install everything(if DUALBOOT) and use custom partition.tbl to give windows partition more space
