Is this true ? When yes, battery is drained due to lack of some system drivers, which may be little different from drivers shared in post OP or Teclast site.

I personally have battery drain on Windows 8.1 Pro, is there anybody, who has battery drain on Windows 8.1 with Bing ?

Please anybody "who has not problem with drain in Windows", please export your device drivers information and post it to this forum, I will analyze that with my export.

1) run "cmd" as administrator

2) type "driverquery.exe /fo csv > c:\driversinfo.csv", press enter

3) attach file c:\driversinfo.csv to this forum

For complete analysis, we need scheme of Connected Standby too, so please export powerscheme:

1) run "cmd" as administrator

2) type "powercfg -export c:\scheme.pow 381b4222-f694-41f0-9685-ff5bb260df2e", press enter

3) attach c:\scheme.pow to this forum

and export whole registry key HKLM\System\CurrentControlSet\Power (it allows us to try(import) your powercfg settings without going to powercfg control panel)

Thanks

EEPROM Bios Flash using SPI Programmer

Has anyone flashed the Bios using the SPI Programmer from a Windows 8 computer, or has everyone used Windows XP to flash?

I am getting a strange issue where the CH341A software says Connected right after I plug-in the USB part of the SPI programmer to the computer but I haven't even connected the clips to the Bios chip. When I actually do connect the clips to the Bios chip the status changes to Not connected.

So its the opposite of what you would expect. Anyone else face a similar issue when they flashed their Bios using a SPI Programmer?
[Teclast X98 Air 3G] grigoris_a:
There is no point in doing that.Teclast Windows with Bing also have drain with dual boot bios.It's a bios issue.You can try your self.Install air 2 bios to your existing installation and the battery drain will disappear.If you install dual boot bios it will appear again.And don't worry you won't lose your android install by doing this.

[Teclast X98 Air 3G] Graf Schmidt:
Nope, there isn't.

I'm afraid I need SU privileges.
[Teclast X98 Air 3G] mirek190:
In that case if some dump bios 1.05 from new devices we probably solve the problem with battery drain [emoji4]
[Teclast X98 Air 3G] melvincz:
That means the clip is not connected correctly to the chip. Either you're not connecting the dark wire to the "hole" on the chip or you have to reconnect the clip while moving a bit to the left or right. Also, sometimes it says "Connected" but flashing is not successful. You need to see correct chip info after clicking the "Detect" button. Give it a few tries. I've already flashed several times and there were many uncorrect connections.
[Teclast X98 Air 3G] Graf Schmidt:
Lol I am trying to backup mine, but I am sufficiently n00b that I'm unable to locate the .bin file "fpt" created - it's not on pc, I've search everywhere, must be under root dir on the Teclast somewhere, and I am trying to gain superuser privileges in order to see those folders :|.
[Teclast X98 Air 3G] mkumar12345:
Thanks for the help melvincz. Did you use Windows 8 computer to flash?

Did the software say connected before connecting the clip to the chip for you? From everything I have read before you connect the clip to the chip it should say Not Connected. If the connection is not correct then shouldn't it say "Not Connected" both before and after connecting the clip to the chip?
[Teclast X98 Air 3G] mirek190:
If you was backup without su then not possible to crate file in root .

Only in /data /cache or internal memory
[Teclast X98 Air 3G] ImJamIN:
Ok, Try with this backup_bios.bat modded. Probably there is an error in the bat file
[Teclast X98 Air 3G] mkumar12345:
If I jiggle the clip to a state where it keeps saying "Connected" (note that I don't get the windows hardware connection sound when I do this and my guess is that it is still not connected), when I click Detect I get Manufacturer: Other, Memory: Unknown etc., like its not reading anything.

Also if I try to Program it in this state, I get a "Write Operations TimeOut Failed" message very quickly.
[Teclast X98 Air 3G] Graf Schmidt:
Run new batch, it says:

C9J8.bin file already exists.

I can't overwrite nor quit the cmd window.

And I am experiencing problems in getting root permissions with the tools in the first page. Using vRoot just push into my device a window entirely written in chinese :D.

I should try: TOOLBOX WITH SU - updated to 2.43

I am not sure of the result though.
[Teclast X98 Air 3G] melvincz:
Yes, I'm using x64 Windows 8.1 computer :) It says connected once you plug-in the USB programmer even before connecting the clip. Incorrectly connecting the clip will switch it to "Not connected" status.
[Teclast X98 Air 3G] sauliusz:
You can try flash windows only bios and then for android use amiduos .com It looks promising if you don't need much from android :)
[Teclast X98 Air 3G] melvincz:
I've been frustrated while unbricking my tablet as well :)

There are exactly 3 states (in majority there is a sound of connected/disconnected device):

- connected correctly (try to push the clip gently from top down to the chip while connecting), detection shows correct values, everything works.

- connected incorrectly but saying "Connected". Detecting some ****ty info and showing timeout.

- connected incorrectly and saying "Not connected" - try to rotate the clip and connect - you should get into the state...

For me the sequence of "Clear" - "Blank" - "Program" - "Validate" operations was the only one working while having detected correct info.
[Teclast X98 Air 3G] ImJamIN:
Yes, You can use the new toolbox.

Anyway this is a new version of backup_bios.bat. Try it.

hi, I can not install the drivers for ADB teclast on my windows 8.1 64bit .... tells me that the syntax of the INF file is wrong .... how should I do?
[Teclast X98 Air 3G] jacfry:
I wrote that few days ago. I was on Windows and every thing was ok. Sometime I entered bios to see what the options are. Before exit I chose "Restore Defaults" and then "Save Changes and Exit" (I'm not 100% sure that I didn't change anything unintentionally after restore but before save) Tablet didn't turn on no matter what I did until I flashed Winbond 25Q64 chip with X98Air3G.bin using SPI flash programmer built on Arduino Duemilanova using flashrom software under ubuntu.

Right now I compared the bios settings and the ones which are saved with X98Air3G.bin are different in some areas than the ones that are set after restoring defaults. Differences are below..

Feature : X98Air3G.bin : Default

Advanced -> LPSS & SCC Configuratnio -> LPSS PWM #2 Support : Disabled : Enabled

Advanced -> OS/BOM Configuration -> DPTF : Enabled : Disabled

Advanced -> OS/BOM Configuration -> fTPM : Enabled : Disabled

Advanced -> OS/BOM Configuration -> PAVC : LITE Mode : SERPENT Mode

Advanced -> Thermal Configuration : more parametrs : less parameters

Chipset -> South Bridge -> USB Configuration -> USB OTG Support : Disabled : PCI Mode

Chipset -> South Bridge -> USB Configuration -> USB VBUS : ON : OFF

Restoring defaults and choosing "Save and restart" didn't cause any problem. The settings after restart are the same as in X98Air3G.bin so the changes made by restoring defaults were reverted during boot.

Info below is not relevant to anything as it changes after restart:

Under Advanced -> OS/BOM Configuration devices are set to different types

componenet : X98Air3G.bin : Default

PMIC : Xpowers or TI : Xpowers

Rear Camera : GO GNDF130928-C : Lite-On 12P2BA535

Front Camera : GO GNDF130927-B : Lite-On 13P2SF221

battery capacity

Hello guys, I have this tablet ( x98 air 3g) and I was looking to its feature in the official website. They said that it has a 8500 m.Ah battery, but the new version of cpu-z app shows only 4980 m.Ah!!!!! Can anyone approve this also?? I think maybe they lied to us.

Just received my new Teclast X98 Air 3G via slow boat from China and after the OTA updates am pretty happy with everything except battery life. I don't intend to switch to Windows but need to root to apply the fixes available via the Battery Doctor app re battery life.

I have read all the way through this thread and understand VRoot is the way to go and have found pages with instructions but am remain it confused. A couple of posts mention that one has to use KingRoot first then VRoot in order to root this tablet but I want to be sure that this is the case. I haven't found anywhere with instructions on how to use these two apps together either.

Is KingRoot really necessary or can I just use the VRoot app to get the tablet rooted?
[Teclast X98 Air 3G] thebigfatman:
For most people VRoot is able to push its daemon onto the device, but the windows client never goes past the detecting phase and the "root" button never turns to green.

Running Kingroot seems to get the train going. Once you've tried to root the device with KingRoot (but it fails), then VRoot is able to continue the process (and works)

Then, for a fully english solution, find SuperSU in the MarketPlace and update the binaries. VRoot's client will ask you for root permissions, and once the process is done you can uninstall VRoot and restart the device with SuperSU as your root handler.
[Teclast X98 Air 3G] Alexdad54:
Thanks, I'm a noob at this but I think I understand everything you've suggested except the SuperSU part in which I should " update the binaries.". Most forums suggest doing this via recovery mode but I'm not sure how to do this with the X98. Should I utilise a tool like TWRP?
[Teclast X98 Air 3G] thebigfatman:
There's no custom recovery for this device yet, so SuperSU cannot be flashed via TWRP or CWM.

However, you can get the app from the PlayStore and when you open it it'll pop you for the update on its own and ask for root permissions. It's not mandatory to switch to SuperSU once you're rooted but the KingRoot version is not in english (but obviously not too hard to figure out)

i still cant get my it to locate my tablet when I input adb devices
[Teclast X98 Air 3G] mkumar12345:
I have now tried this atleast a hundred times. There was only one instance where I was able to click Program button without it throwing the Timeout error immediately, but it gave an error when I clicked Verify.

I am matching the Pin1 (the pin where the dotted red line cable is going to) with the chip end with a circle mark on the top. I also tried the other way but no dice.

Even when I sometimes land into Connected state, with the clip attached to the chip the software doesn't detect the chip info and its always some default crap. So, I wonder if the clip is just not connected well and its showing the connected state of the Programmer itself. It can't be this hard, can it? You would think with a hundred tries I will land on the magic combination atleast once.
[Teclast X98 Air 3G] vpx:
So it looks, that UEFI for dual boot lacks some power saving code, so we have to inform and ask Teclast to solve this issue, isn't it?
[Teclast X98 Air 3G] melvincz:
So many times should be enough. However, my number was similar before I've found, it's crucial to push down the clip when connecting. Pin1 to the circle mark - yes, that's correct. Try to exit the app, disconnect clip from the programmer, unplug the programmer and repeat. It seemed to me there is something magical when I was flashing my tablet.

Windows battery drain

Hello,

it seems the only solution now for dual boot BIOS and avoiding battery drain is using an Air II dual boot bios. I remember reading here that 3G works perfectly and only "cons" point is that GPS is lost. My question is....GPS is lost only for Windows? Or also lost in Android? Not than I am using tablet for GPS, but better to keep functionality just in case even if just in android...

For sure new users with 1.05 Dual Boot BIOS can confirm in their devices suffer Windows Battery drain or not, and we will have a dump soon if this new bios is the solution!

Thanks everybody for this brainstorming thread!
[Teclast X98 Air 3G] HDtracer:
I dont know. When you first plug the tablet in windows automatically does the whole new device found/installing drivers thing. That lets the device connect as a media device, can it do that?

I would try uninstalling any adb drivers and starting again.

Can try this driver http://www.koushikdutta.com/post/universal-adb-driver
[Teclast X98 Air 3G] Graf Schmidt:
Keep changing name doesn't solve the problem :D.

adb pull /data/local/tmp/C9J8_105.bin

This instruction should "move" the data the program read to that directory. Is there any instruction to just copy it to storage or somewhere I could read without root permissions?

Stand by???? Not shutdown complet.

Hello all,

I got another tablet C8J7. I installed X98 Air 3G (C8J7) mirek190_v3.1, dual BIOS and Windows 8.1. Everything is ok, but I have one big problem; tablet does not close completely. I think it remains in standby. Even if I shut down. If you want to start and push the power button the tablet does not start. It must press the power about 12 to 14 seconds and then starts normally. How can I stop completely tablet?

And if you do not stop holding the power button down for about 12-14 sec tablet continues to provide power to the USB port for USB hub and keyboard stay on.

windows is in Single language and i cant even get it to Change, Not to mention it isnt Dualbooting

properly, not allowing me to change the partitions, it completely erases all the partitions because

its using WinPE. i just want to set my tablet back to normal with what it came with but ugh, Even Geekbuying

adb shell cd /data/local/tmp; ./FPT -D C9J8.bin

BIOS 1.05 from C9J8

Ok, I've managed to get the .bin file.

It was a syntax error: this instruction needs a "." at the end "adb pull /data/local/tmp/C9J8_105.bin", since syntax is "adb pull <remote> <local>" and "." means "current dir".

I just needed to call a batch with new syntax to get the bin out.

Go /etc/init.d folder and create a file named 91Fastmode (for example). Rename the actual file 99SuperSUDaemon to 90SuperSUDaemon (to execute before the FastMode one).

Inside the 91Fastmode file add the lines

#!/system/bin/sh
echo "FastMode" > /sdcard/FastMode.txt
su
echo 400 > sys/devices/pci0000:00/0000:00:02.0/drv/card0/gt_min_freq_mhz
echo 400 > sys/devices/pci0000:00/0000:00:02.0/drv/card0/gt_max_freq_mhz

and give 0755 permisions.

After reboot the GT_ files are changed...
