No - from old version 4.4 they have diffrences structure and won't work on lilipop.
[Teclast X98 Air 3G] ImJamIN:
I didn't know it. I have read that on stock lollipop the camera works on every device, so I think that you have changed something (driver or other) for optimization.

If so, this is a little/big problem and we cannot do so much to resolve it. :(
[Teclast X98 Air 3G] tecknight:
sahor,

Unless Teclast decides to post the source code for their ROMs or the source for a nearly identical device becomes public, we will likely have to wait for Teclast to release a 5.1 image. BTW, there are very few nearly identical devices, most non-chinese devices using a Bay Trail SoC use a completely different GPU

Update the BIOS on your X98 Air II/3G to the latest dual boot version (2.02)

I just saw that you don't have a Windows PC. Maybe you have a friend with a Windows PC ?

Cuz I don't think you will find any instructions on updating the BIOS from linux.

You can install adb in linux, but the .BAT file will not run under linux
[Teclast X98 Air 3G] droutis:
3.8 Gb is very little free disk space to do the job through thw upgrade utility alone.

I performed the following steps to successfully upgrade Windows 8.1 -> Windows 10:

- created USB stick through the update utility you mentioned earlier (for install to another computer, be very careful to select 32 bit edition)

- factory reset from inside Windows 8.1. That alone created around 10 Gb free space in Windows 8.1 partition

- installed Windows 10 through the setup program in USB stick

- updated G-sensor driver + Intel display driver http://techtablets.com/2015/07/teclast-x98-air-3g-windows-10-update-and-windows-10-drivers/

Windows 10 worked like a charm!

Hope this helps.
[Teclast X98 Air 3G] sahor:
I don't know if Teclast is a company which update firmware frequently... I only know that Pipo didn't and I hope that Teclast will be better in this situations.... You maybe know more about Teclast... Is the situation that you describe really possible?

Android Strange issue

Hi guys,

I don't know what happened, but since yesterday Android is asking me for the wifi password every now and then; sometimes 15 minutes into using it, it just disconnects and doesn't remember the password. Also the icons once in a while will just go away, as if the apps were deleted. Really strange.

I have the HG6N model (Air II) on BIOS 2.02, with Mirek's KK latest build. I also am running Link2SD to save space, which is one of those things I suspect could be partially responsible...

Anything I should try before re-flashing? I tried disabling the automatic backups, saving the password, and re-enable backups (found this as a suggestion somewhere), but it didn't help.

Thanks!

Michel

[Teclast X98 Air 3G] microb77:

[Teclast X98 Air 3G] PDPR:
I have HG5N (same than yours but without windows) Did you have problems with cameras on Android using latest mirek's KK?
[Teclast X98 Air 3G] microb77:
Nope, still not working. So I decided to go ahead and try a few things, as I think Mirek asked earlier to give that a try...

I have a HG6N, so I have the camera issues. Since my Android was "broken", I decided to give in to the science and experiment with different ROMs from Mirek.

Results:

X98_Air_3g_android_5.0_mirek190_v4.1

no camera

Entering the camera app didn't crash the tablet, just the black screen with the camera icon.

Seems very fast compared to KK.

X98_Air_2_android_5.0_mirek190_v4.0

no camera

Entering the camera app crashes the tablet as reported by others.

Strangely, this one says "Android is upgrading" when starting for the first time.

Did not reboot on language screen, only after WiFi selection, which ended in strange reboot behaviour.

X98 Air 3G 4.4.4(Air2) mirek190_v4.2

Works fine, camera and all..

I just am a bit concerned as I had the earlier mentioned issue about wifi and losing apps. Strangely, I would reboot and the apps are back. I am wondering if it is not a dual boot issue related to the SD Card issue I have with Windows when switching OS through software...?

Will remain on this ROM until a working lollipop comes out for this version as no skype is very bad for me on this... (as most of us who complain about camera!)

---------- Post added at 02:56 PM ---------- Previous post was at 02:40 PM ----------

No the cameras work fine in Mirek's latest Air II KK ROM. I actually went back to it for that sole purpose!

Front camera is not working in Windows - so I will be trying the "miracle" I read about yesterday a couple of pages back, something about some Intel drivers that may fix that...
[Teclast X98 Air 3G] Franckydiam:
:) http://xdaforums.com/showpost.php?p=62333476&postcount=11722 for me and my c9j8 under kk v4.2, its work fine, all camera in android 4.4.4 and windows 10 :) Perhaps
[Teclast X98 Air 3G] microb77:
Yes, that's what I do with my HG6N as well. But it means saying bye bye to the front camera in Windows (if going to BIOS 2.02).

And I would like to note that the drivers from lenovo provided a few pages before didn't work for me - Windows 10 will not boot anymore... Back to re-installing it again.
[Teclast X98 Air 3G] tecknight:
You make an excellent point. I guarantee you he has NO help from Teclast and yet he ALWAYS manages to improve Teclast's ROMs significantly with no detailed hardware address map and no android source code. Please understand the significance of this and the amount of attention to detail that is required. Every one of us that owns an X98 is very fortunate that Mirek is willing and able to create these ROMs for us. Without them, the X98 would be pretty boring and slow on the Android side.

Thank you for your great job!

I have X98 c5j6 64gb and after installing your last ROM (I came from your Kitkat version and made full wipe as advised by you)

I have a lot of freeze very randomly on all kinds of apps.

I understand you work on better version to fix it. Meanwhile can you explain how excactly to make the changes you suggested to GPU or other settings.

Where and how do I change these settings?

Thans!

[Teclast X98 Air 3G] ceptic:
PDPR,

It isn't that hard to mod all of the camera xml files in system/etc. I used root explorer to change the folder permissions to r/w and opened each file in text editor. At the top of each file look for the line with 'orientation' in it and change the value with the following inverted commas by 180 degrees as you said ie "270" becomes "90" and "90" becomes "270". This is the only change you need to make in each file. I saved and exited, checked permissions (mine hadn't changed). I now have a correctly orientated camera... so big props to mirek190 and you for this discussion.

Very happy with v4.1 ^^, tomorrow is windows10 D-DAY :D

EDIT: do you know how to display the battery percent on status bar?
[Teclast X98 Air 3G] ceptic:
If this rom comes with xposed and gravity box, like mirek190's 4.4.4 rom does, you can activate gravity box and adjust the battery indicator or percentage. Currently I have the kitkat battery with percentage on my status bar.

The 3.3V CH341A. I have a 1.8V EZP2010 programmer on order, but The CH341A did the job with no ill effects.

Also, I just flashed your 1.08 BIOS (fixed to be flashable). You and I have the same Air II mode (HG9M, although mine says HG8M on the case, I assume because the case was manufactured before dual boot). You have a front working camera in Win 10. I don't and 1.08 did not fix it. I assume yours shows an OV2680, like mine. Mine still shows the dreaded STATUS_DEVICE_POWER_FAILURE error. I've tried various drivers, uninstalls, etc. So, it's not clearly a BIOS issue.

As far as you know I'm working on v5 lilipop ...

Yesterday I finally rebuild all apps ( properly yay ) in rom for x86 and see4.1 optimisations and removed prebuild system x86 apps.

Now the tablet in first run must build all apps itself with optimalizations in vm ART ( no prebuild app anymore ) - it takes x3 time longer 1st boot but later on 2nd boot is 2x faster booting compare to v4.1 .

Even apps sems work faster or maybe is my imgination ...
