Hey guys,

I just received my Teclast x98 plus (A5C8) and did a fresh installation of windows 10 german.

I know this is not the right thread, but maybe someone of you had the same issue with windows and touchscreen.

Everything works just fine.

But after some idle time (display off) or random restart the touchscreen stopped

Can anyone help me out?

Best Ragards,

Dominik

Cwm & remix os

I'm glad to see you back on track! :)

Have you seen that we have a custom recovery for our lovely tablet?!

And what do you think about the new Remix OS 2.0: a porting for our device would be possible?
[Teclast X98 Air 3G] javiti:
HI guys, does exist any Android ROM without the bright problem and good battery performance? I got the Air II HG9M with dual boot

I´m not using my tablet because it constantly change the bright (because of the temperature I assume) and the battery falls when it reach 50%. I´m just looking for a stable Android version because i´ve realised i dont use windows.

I do not have that model so I can not to develop that ...

You have android 4.4 ?

Change kernel to c5jx for 4.4 then will be ok

Or use my rom for air 2 .

---------- Post added at 03:11 AM ---------- Previous post was at 03:09 AM ----------

Recovery is not very useful on our devices ... because is hard to get there ...

Remix 2.0 is based on android 5.1 ?
[Teclast X98 Air 3G] supercowz:
hi mirek190 how are you

i did have the X98 Plus now

i did root the tablet, since no root method was advable, all root method for any teclsat X98 model, all know prog like IRoot, kingo root, framaroot, kingroot, and even IntelAndroid-FBRL-07-24-2015 fail but work great on most intel tablet include some Teclast X98

so under linux unpacking boot.img edit it and repack.. story then create small batch to add supersu

i did grab/get the system.img, unpack it and edit/repack it, but fail to boot, i guess is about sparse, if you can explain me the right way .... im still learning, im not at your level

with your help, i can made, we can made custom rom, so the comunity can enjoy custon rom for X98 plus

thank in advance :)

Ps :
[Teclast X98 Air 3G] mirek190:
You was making rom for x98 air some time ago wasn't ?

The same method for for repacking not works ?

Use goolge tools for that - to compile them from source is the best method.
[Teclast X98 Air 3G] supercowz:
did not made custom rom for teclast, with kitchen yes for other device, but need custom recovery, we dont have that with teclast tablet :)

never done that before, i mean compile from source, do you have any link explain/teach me that ? im confuse how to

there no way to grab modified system.img fron the x98plus tablet ? then use fastboot to flash it back ?
[Teclast X98 Air 3G] maxedout56:
Thank you.

I tried to update the bios to 2.02 and now my tablet does not start. I tried pressing the power button for a while and everything i can possibly think of. Is there a way to fix it now? I am so confused :(
[Teclast X98 Air 3G] deathrowz_sri:
Need some advice guys. Wondering if its safe to flash any one these bin files using USB programmer.
[Teclast X98 Air 3G] javiti:
Thanks for the reply. Actually i´m using one of your Lollipop´s ROM.

You recommend me to downgrade to 4.4 or there is a kernel for the lollipop version that will fix these problems too?
[Teclast X98 Air 3G] cattolicboy:
What do you mean by "because is hard to get there"?

I have managed to install it and test the functionality and, apart the slowness, seems to be working.

Yes, Remix OS is based on LP 5.1 and they have the EFI version (both the x86 that x64 architecture) and I have heard that someone have already installed it on our tablet and both the display (must had been connected to an external one through hdmi) and the touchscreen (must had been used an external keyboard) weren't working.

I know that Teclast didn't provided source codes and that the last android release is LP 5.0: would this be the issue for non compatibility?
[Teclast X98 Air 3G] Mikha777:
Have you followed the instructions carefully and received the successful message at the end of the flash ?

Give more information about what happened please :cowboy:

---------- Post added at 08:34 AM ---------- Previous post was at 08:33 AM ----------

Yeb since with a CH341a programmer you can flash any firmware you want easily. :cyclops:
[Teclast X98 Air 3G] deathrowz_sri:
Thanks for your advice. Did everything according to steps, detect, read, save, erase, blank, program and verify. I desoldered red battery wire prior to flashing and soldered it back. Left to charge for some and no sign of booting. Anything im missing here? Please your help much appreciated.
[Teclast X98 Air 3G] Mikha777:
OK it's with a CH341a I was thinking it was a "softflash" with Intel FPT tool.

If it your tablet was not charged previously first I will let it charge fully ( 3-4 hours) first. For mine I did not disconnect the battery at all.

If it did not boot after 3-4 hours on the charge first things will be to test if the battery have some charge, you can connect directly your charger to be sure there is some current.

If you have current and it did not boot first thing to do is to test your firmware with CH341a to see if you are able to READ/WRITE/ERASE begin with the READ Test and compare the content of the Firmware against the .bin file it supposed to be inside the firmware.

Let me know from there how it react ! :fingers-crossed:

STRANGE BATTERY C H A R G I N G problem

Dear All,

I am writing here knowing that there is a huge possibility that I will not get an answer, just like in few of my oldest inquiries. I really need the experience from the people that might know how to solve a STRANGE BATTERY C H A R G I N G problem. I have downloaded and followed and installed dual OS Android Mirekl's 1.86 something... and Windows 10. That happened almost a month ago and everything was working perfectly till last week.

(In the android version)

The problem started out of the blue when I tried to charge the tablet. At first I noticed that the battery didn't last for more than 2 hours, (Voltage ~ 4.340).

Then I noticed that the battery was charging from 0% to 100% extremely FAST. Less than 1h50mins.

At that point i noticed that: When the battery is charging and the meter show 100% (in android version) if i remove he charging cable and plug it again it will continue charging from 40% to 41%.

Due to Advance Battery calibrator App I get a beep warning when the batter charges up to (faked) 100% so, when the battery charges +1% (e.g. 40% to 41%, 42% to 43% , 92% to 93%). the app beeps and the battery meter shows 100%.

Then I have to remove the charging cable and plug it again to the tablet to charged it 1% more and it goes on and on like that up to 96%.

The tablet cannot charge more that 96%.

I do not mind if the table cannot fully charge to actual 100% and it charges up to 96%. but i do mind that every 1% i have to plug in and out the charging cable.

What I have done till know

1) Switched off tablet pressed Power Button + Vol up, enter the menu and did a full reset.

2) Switched on the tablet pressed on factory setting and did a full reset

3) Download 3 different apps that "calibrate the battery" and "created" a new "batterystat.sys" file (or something like that).

The problem persists and I have to charge the tablet every 1% every 5 mins
[Teclast X98 Air 3G] supercowz:
yeah oki right, and i solve my img repack problem, now all good

thanks for your advise:good:
[Teclast X98 Air 3G] mitchy24:
Same problem with a Samsung tablet . tried a different cable , works great now . hope it does for you .
[Teclast X98 Air 3G] JagSagaz:
Try what the former colleague has just said (change cable) in case it could solve your problem.

If that doesn't help and this charging problem keeps on happening with both OS, maybe you must assume that your battery or the charge chip are damaged in any way and must be replaced.

Good luck, friend.
[Teclast X98 Air 3G] deathrowz_sri:
No this is using the usb programmer and clips. Quite strange that after i plugged in to charger and left it for about hour and checked the battery is warm to find out cpu and ram area is warm. I was worried and removed power. I have misplaced that aluminium sheet covering cpu and ram. Do you think its causing short circuit?

I had 2.02 dual boot firmware when i bricked my tablet. I flashed the newest firmware. Will that mismatch also cause it not to start?

How do i directly connect the charger and see battery has some charge? I checked the charger with my phone and it charges as usual.

Really appreciate you helping me out. Thanks!
[Teclast X98 Air 3G] Mikha777:
The aluminum sheet is a heatsink to cool down the CPU and ram when it work, if it was NOT touching any lead or trace on the board you should be fine.

But it's normal that the battery/component become warm or even a little hot when the battery charge.

What is the firmware version did you use for flashing the firmware ?

Anyway at anytime you can flash back 2.02 firmware without any problem, if everything work fine with 2.02 Firmware I would stay with 2.02 since 2.05 don't seem to have enough features to justify the hassle.

You just connect the charger directly (as usual) on the X98 and it will draw power from the charger. :cowboy:

Let me know how it turn ! :o
[Teclast X98 Air 3G] deathrowz_sri:
Still bad news. Earlier I had 2.05. Yesterday i re-flashed 2.02 dual boot. Everything went ok, detect, read, write etc. Then left it to charge overnight. It seemed charging with charger getting warm.

But when I pressed on power, nothing. Just dead.

Running out of options. Thinking of giving to an electrician to see all wiring is ok.
[Teclast X98 Air 3G] Mikha777:
:( Humm, it don't look good, at least you know that the firmware is fine but why it don't open when you press on the power button is hard to understand. Only thing I see is that you have inadvertently shorted the board somewhere :confused:

Like you said having somebody else with more experience looking at the board should help to find what happen. :)

Good Luck ! :cowboy:
[Teclast X98 Air 3G] Nimn:
My dearest,

I have changed the cable and the charge as you have suggested me, but the problem remains. I have attached few screen shot to present the problem.

After a full charge up to 97% I did a new battery calibration and now the battery charges up to80% only.

GOOD Results in SleepStudy & Windows 10 in Sleep mode after Tweaking advanced Options

Very GOOD Results in SleepStudy & Windows 10 in Sleep Mode after Tweaking Advanced Options

I had to use my X98 lot more on battery those days and results in sleep mode were deceiving since I had the "stock" setting from Windows 10 (Power Advanced Options are nor enabled in Windows 10). That's why lot of users have trouble with poor standby time especially after upgrading a clean install of Windows 10 since advanced setting are under-optimized :p

Here's the Before (with stock setting) and After (Tweaked Advanced Options):

:cyclops:

Here's the detailed results of the sleep study:

:silly:

Here's my setting right now, if some users have problem in sleep mode it's a good start with those setting:

Note:

Those setting are hidden by default you need to edit your register to make them available. Here's a link where it is explained how to unlock them: http://tinyurl.com/hsreqdo and I use Registrar editor to edit the registry it's more easy and fast than regedit: http://www.resplendence.com/downloads

I think I could be able to squeeze a little bit more juice from the battery if I study the settings a little bit more...

So I will study more and optimize the setting for daily use (not only for sleep mode) and I will post my results later. :angel:

Let me know your results of if you have hints on how to squeeze more juice from the battery :cowboy:
[Teclast X98 Air 3G] simpledisaster:
I'd like to report back that Mikha777's tutorial concerning "unbricking" the 98x Pro worked flawlessly. I carried it out without desoldering the batter wire - I just let it run out of juice for a few days. The shipment came within 15 days from China (I used China registered Air Mail). Reflashed to 2.05 during reprogramming and I'm happy! Thank you so much for helping!!
[Teclast X98 Air 3G] -vpa:
Mikha777, there is possible export settings from registry? Thanks
[Teclast X98 Air 3G] Nimn:
I think the battery is in better shape while in windows. I read your post in regards to regedit and battery option power managent. Here is my energy report after enabling few of the settings.

In android version the battery still charges upto 80%while in Win10 goes full 100%
[Teclast X98 Air 3G] Mikha777:
I will finish to tweak the settings and try to find an EZ way to export/import it with script or registry, manually it's VERY long to edit the registry to unhide those settings :cowboy:

It could be very useful on any computers/tablet that use "Connected Standby Feature" like X98 since by default you only have access to few settings. :)

Follow my post here and I will give some news about it soon. :silly:

---------- Post added at 12:40 PM ---------- Previous post was at 12:26 PM ----------

So your problems are mostly software/drivers problems on Android since on Windows it's "Fine", but even if technically the Windows side is fine

it could be optimized a lot more

than default setting. Windows 10/Microsoft power savings defaults are very under-efficient for use on battery. From my research even their own Surface Tablet have lot of problems (poor life time on battery) after being upgraded to Win 10...:angel:

Try to make

POWERCFG sleeptest

from admin prompt it will give you a more accurate picture.

I don't use Android Windows is enough for me at this time so I can't help you for Android but like I told on my previous post I will try to find a convenient way to Import/Export those hidden settings for users that wanna try them. :silly:

Ive been having a hard time updating the bios. The file to do it seems different than what the tutorial shows. Could anyone PM me with some help9
[Teclast X98 Air 3G] Mikha777:
First thing to do is to find the the 3G modem in the "Windows Device Manager"

Here's an example with a Dell 3 G modem

After you go in the Device Propertie (Right Click) and you should see something like this:

Here's it is an Intel Centrino example it can differ a little bit but you should check the box: "Allow computer turn off the device..."

This way it should use lot less power in sleep mode :cowboy:

[Teclast X98 Air 3G] maxedout56:
I downloaded the bin file which you sent me but I did not know how to update the firmware so I downloaded the update firmware archive from the first page and replaced the bin file to 2.02 and just ran the script on my tablet. It updated and it showed something in Chinese and it was successful and wanted to me to restart so I reset the tablet and after that it won't turn on
[Teclast X98 Air 3G] Mikha777:
I never used any other method than UEFI for flashing firmware so I can't really tel what happening with this script BUT from what you tell the tablet seem bricked and if I'm right (on the brick) you will have to use a CH341A programmer to unbrick the tablet. :cowboy:

It's not very expensive it cost less than $10 but it take few weeks to arrive to your door from China. :o
[Teclast X98 Air 3G] maxedout56:
I have tired everything to turn it on but it doesn't turn on. I guess it really is bricked. I ordered the CH341A programmer. I also downloaded the tutorial to unbrick the tablet from your signature. So hopefully it will be working soon.

Can you also check the resizing partition link in your signature? it is not working. I need that information once the tablet is unbricked.

Can someone tell me how to only update the android to mirek190 rom without touching the windows partitions?
[Teclast X98 Air 3G] Mikha777:
You're right the link is broken for this tutorial since the server has been closed, I've send an email to the owner to have a copy of the tutorial so as soon I will receive it I will the the link to a new server/URL.

If it is not done in 1-2 weeks let me know by quoting one of my message here so I will receive an email to tell me that somebody mentioned my name here since private message don't seem to work for me ... :cowboy:

BTW it's very easy to flash the firmware just take your time to install the clip you may need few try ;)
[Teclast X98 Air 3G] mirek190:
You bricked you devive because you turn off or restart device via Android menu propably after the flash ?

You should keep the power button until the devive turn off ... that's it .

If you have used my tool then won't be any problem :) .

Now you have to use the programer ...

Dear Mirek190

I am the guy with the strange battery drain and charge problem.

Few posts behind, you suggested me to go at

Win10》

Device manager》

Network adapter 》

Find my 3g adapter

Properties》

Power Management

And tick on the "allow the computer to turn off this device to power save".

The problem is on my 3g adapter I do not have the power management tab.

On the other hand the tablet does not charge more than 21% anymore.

I am thinking to flash it again

Could you tell me where to find the correct bios and latest android update for teclast x98 3g c9j8.

On the 1st page of this forum somewhere says bios for c9j8. I did install it and on the setting of the Android it describes my device as c5j6 or something.

Hi scopemind...

i have an c5j8 and also the blank black screen after flashing.. some other guys too...

It happens only with the flasher of the 7.0 version..

We used the flasher of the 6.0 Version and the data of the 7.0 Version... that worked... but i dont know if this is the right solution for you... you should ask mirek if its save to do so !

I hope he will find a solution for the next version...

Teclast X98 Air 3g GPS problem.

Hello guys. I have Teclast X98 Air 3g, C9J7 (dual boot), one of first batches that has come from China, and i'm facing a strange problem. My GPS is not working!

I tried several GPS status apps on Android, and neither one is receiving any signal. GPS is turned on, but no signal is visible in app. I duplicated experiment on my phone (LG G3) with same app, and as soon i started app, it keeps "seeing" satellites and receiving signals. On tablet there is not slightest hint of signal. I also tried with AGPS, but no help. Tried several different ROMs: original Teclast KK; Mireks 5.1 (KK); 6.1 and 7.0 (LP), but no GPS signal on any of them.

On Windows 10 same thing: GPS is recognized, driver is loaded (also tried several different drivers), but no GPS signal. When checked with sensor diagnostic app, all other sensors are working, but on GPS sensor tab it states "initializing".

Also tried several different BIOS versions: 1.03 original, 1.03 first dual boot BIOS, 2.02, 2.05 - but no help. No GPS signal on any of them.

One thing i noticed on 1.03 first dual boot BIOS (one with much greater options set!) is that on one page, next to the GPS field it states "disabled", but that field is not editable! I don't know how come my GPS became "disabled", because i'm pretty sure that GPS worked before. I didn't tested it extensively, but i tried it with Google Maps and some GPS apps, and it worked well.

Please guys, share some ideas because i desperately need GPS and it suddenly stopped working!

I tried Windows 8.1 with Bing, 8.1 Pro and now on Windows 10. I think that Windows 10 is the best.
