Something is wrong with battery. Reports twice less capacity.

How to fix the issue? Anyone has stock 4.4?
[Teclast X98 Air 3G] reachforthesky:
Will the camera work on the M5C5 model? It is not stated on OP's post.

TIA
[Teclast X98 Air 3G] niflo:
I havent tested it if it works, but in his 2nd post OP says this:

alternative kernel --------------------

( boot.img ) for air3 ( c5m5 ) that fix the camera

And there is a download link.

---------- Post added at 08:04 PM ---------- Previous post was at 07:58 PM ----------

I was searching for fix for weeks, and from what I read this bug persists at many Teclast models (air 2, air 3, air 3g etc.) and for now no fix exists.

---------- Post added at 08:19 PM ---------- Previous post was at 08:04 PM ----------

If you cannot install the drivers, depending on your system search youtube or google for

How to install unsigned drivers on Windows 10

You will find many videos/articles explaining how to do that.

Teclast x98 3g C5J6 not work

Hello everyone, from about 30 days I have a problem with my air teclast x98 3g C5J6 explain to me, has trouble to boot both Android (version V7.0 mirek190 lollipop) and windows (windows 10) the few times that lights up Android after about 2/4 minutes turns off automatically when it happens I noticed that the battery on the next reboot from 96% to 34% I find I tried with windows and this problem would not show up right away but now it's common that in windows mode restarts least three times before it fails the second part of the system recovery and the third works. in recent days to use it I have to keep attacked the alimentaazione I tried to make a battery test with applications but the result is always the same no problem. What recommended me to do?

Sorry for bad english.

Battery drain, YES

Yes, i have the same problem too. It come from the screen that lights up regulary since i flased the v7. You can also desactivate notifications in the Applications menu. It will save the battery (usefull for the games of my daughter...)
[Teclast X98 Air 3G] zsolarewicz:

I went to ROM 2.0 (I suppose)- the one prior to 2.05 - it helped.

I'm using this ROM for more than 6 months and it is much better than stock ROM of Teclast. I do face this random battery drain bug, but still it's enough for day to day usage. To improve battery life you can try Amplify app.

In that case the rom for air 2 is fully compatible with air 3 ?
[Teclast X98 Air 3G] sky|ined:
Everything seems to be working as it should. OneNote was crashing when trying to login but found a way around it and Ad block plus crashed once but was immediately working again. I had about thirty applications restored through Titanium which can cause instabilities some times so I am monitoring the situation in case something like that happens again

Antutu score went up from 27000 before flashing to 32000 after flashing the rom but tablet feels a bit slow for a device that scores this much. I have installed Nova launcher with faster than speed settings-no animations but I guess the lower frequency processor of the AIR lll struggles a bit with the high resolution of the display. To be fair for £91 it's very high v.f.m. Xposed / Gravity box running fine. I will report back after some more use.

In short I would say that this ROM if fully compatible with AIR lll

Incorrect touchscreen resolution

I flashed this Android 5.0 v7 ROM but the display resolution and the touchscreen resolution is not the same.

If I move my finger on the screen then the contact indicator moving only on a pretty smaller area, maybe 20% of the display size.

[IMG="Touch resolution mismatch"]https://img.xda-cdn.com/IptO38cvOX8gE6E4I0voKdWS3Ic=/https%3A%2F%2Flh6.googleusercontent.com%2FNeeuBoP-JOtzkrd_X1MzsAvbL7mZThzJp2ICriOE69YBxuHyLsNQp1GTV8P1HSEw23zX-a9VYo4KwLE%3Dw1920-h971[/IMG]

See the attached picture. (If I touch at the big dots, it reacts at the small dots inside the yellow marked area.)

It is almost useless. At the moment I navigate with a mouse on the OTG.

What I tried:

Download a calibration software

Failed it. I can not found any. Only sensitiveness calibrators exists for Android. On Windows You can calibrate coordinates, but on Android... Somewhere I read that the calibration data is hardcoded in the kernel.

Compare the stock ROM with the newly installed one, search for differences on drivers or config files.

The .idc files are the same in /system/usr/idc, and the .drvb files are the same in /system/vendor/firmware.

Modify the .idc file in /system/usr/idc

I found some content at Android's site about the Input Device Configuration files.

I tried the following parameters:

touch.scale (but it is corresponds to contact area size)

raw.x.max (the maximum of the raw value received from the touchscreen)

output.width (the displqy coordinate to associate to the max raw value)

Anyway I tried almost all touch.* raw*. and output.*

Nothing helps.

Note: I have the skills to extract a ROM or decompile an .apk!

Should I replace a driver? Or is there a handy software?

Should I modify another config file? Or the kernel?

Really sad that development stopped (especially without any notification). Atm my tablet is pretty unusable with terrible battery drain. Nonetheless, thanks [MENTION=2198172]mirek190[/MENTION] for your work, I bought my X98 Air 3G only because of your ROM :)

[Teclast X98 Air 3G] stronzo46:
Hey Mirek is a ROM planned for Model X98 Plus II? That would be great!
[Teclast X98 Air 3G] mick154:
Great.
[Teclast X98 Air 3G] llama1337:
Flash the firmware 2.02 as 2.05 is buggy, may cause battery drain. Not Mirek's fault, it's the ROM code.

For the resolution and screen size, try using the ADB commands to set the desktop size while the tablet is in Dev mode and connected to Windows.

As for bashing the guy, we do not know what has happened in his life to take his attention from this ROM - maybe nothing but how many years do we think he owes us support for a years old device?

Be fair, the final ROM he released is as good as it gets for speed, fluidity, and performance. He supported the device longer and better than Teclast, themselves.

Enjoy what we have or try to lean on the CM team to tie it into the CyanogenMod project. Maybe then we could get Nougat on this device.

Hi all,

Great work Mirek, works nicely on my Air x98 III. The little problems I'm experimenting are similar to the ones I've read in the post:

1) Facebook closing, resolved installing previous version 93.0.0.13.69 and stopping auto updates

2) Sometimes doesn't switch on at 1st click, but I believe it happened with stock ROM too

3) Skype not starting cam and freezing on call, I'll try previous versions

4) Camera working on default app, WhatsApp video call, messenger, but inverted on other apps like camera Fv-5 or QR scan

5) Camera freezes on web WhatsApp QR scanning

I hope you'll have time and motivation to go on with this great ROM

Cheers

I could install RemixOS 2.0 on my C2D4 x98 Plus II / 2.

Download the official RemixOS for Plus I/1

Download the Android 5.1 stock for Plus II/2.

Copy the boot.img from the Android5.1 stock and copy/replace into the RemixOS for Plus I/1.

Use Intel Flash tool in “Recovery” mode (not Update).

Power with + and – volume pushed, wait DNX Bootmode.

[Teclast X98 Air 3G] agustincordoba:
I've been using the Mirek lollipop room for my dual-boot C5J6, initially it was a lot better than stock which came with all the Chinese stuff; unfortunately it ultimately went so slow that I decided to do a factory reset, choosing the in-system option. This is where things went hideously wrong as it got stuck in a never-ending WIPE sequence following which Android did not start again, instead showing the “deleting“ message eternally (and I do mean the whole night long). I see now that what I should have done was to have connected directly in DnX mode and re-flashed the Rom from a computer but I wasn't thinking right (late-night mole bug!). In the end when I actually did this, in spite of there being no error message and the flash apparently correct/ok, the machine still goes back into the unfinishable-delete mode and does not start Android.

BTW, Windows10 is still working fine... Ideas, folk?

Hi all,

Does mirek rom is funtionnal with Teclast X98 Air III (m5c5) ? I've tried to install but after rebooting black screen and nothing append. So return to guvno rom :(

Thanks
[Teclast X98 Air 3G] paulmerrill:
I've gone through a number of ROMs now for my X98 Air II HG9N. They all seem to have similar problems. Firstly, I guess I should describe the machine:

> X98 Air II HG9N

> Android 4.4.4 (rooted) downloaded from Techtablets.com (X98-Air 3G (C8J7)-Android4.4.4-V2.00-(Official))

> V2.05 BIOS

I have tried mirek190 V7.0 rom but it had similar significant problems.

The problems I now face are:

> Battery info indicates the battery has a capacity of about 5000mah whereas I understand it should be around 12000mah...what's happening there and how do I reset it.

> Once it's running it seems to do ok but if I put it to sleep (use the button on the side to turn the screen off) and wait say 20 min or 1 hour, then when I hit the button again to bring it back to life, the screen will appear but the system can be very sluggish for 2-5 minutes. I can see that the CPU is at 100% for a long period.

> Burning a new ROM, like mirek's V7 Android 5 will work fine but I note that the system will over time get more sluggish, to the point it's unuseable. I have then found that if I burn a new ROM, the it comes back to life again (somewhat).

So the main questions are:

1. How does one reset the battery capacity to 12000mah?

2. What is causing this slow degrade to the point of failure and why does burning a new rom sort of fix the problem?

You might have driver trouble, when connecting your tablet to your Linux host.

If drivers are good, then I would open the file "FLASH_tool_Teclast_x98_air_devices-v3.0.bat" in a text editor, and follow the logic in this script file...entering the commands manually in a terminal window.

Else try running a virtual Win7 ?
