I started a discussion about the inaccurate battery capacity under android with your roms.

http://xdaforums.com/x98-air/help/air-ii-inaccurate-battery-meter-android-t3227964

and the user stm00192 mentioned a flashing process that helped him utilize the battery capacity under Android:

http://xdaforums.com/showpost.php?p=63744660&postcount=19

So my question is, do you think that the flashing process is the reason why we have faulty battery capacity under android? I mean, most of us using your super easy .bat file to flash your rom, which uses android's recovery, but stm00192 mentioned that it's crucial to not to boot into android, and the the flashing from DnX mode / Fastboot.

Has anyone tried flashing this on a X98 Air III (M5C5) 32GB? I already rooted and debloated the stock Lollipop ROM, but it seems to have an issue with GPU performance, it's around 30-50% slower than it should be for a Z3735F. I would also be very thankful for any pointers to other ROMs for this tablet.

Edit: Mirek, can you maybe provide the content of this script in a pastebin or something like that?

* GPU-fix -you can under-clock ( stock 580 MHz ) to prevent freezes - you can easily change it in ( /system/etc/init.d/gpu-fix )

I think I have narrowed the bad GPU performance of the X98 Air III down to it staying on base GPU frequency (314 MHz) and not scaling up to full frequency. I was hoping your gpu-fix script where you influence the maximum GPU clock might give me some pointers on how I could try this out.

Flashed v6 on my air 2 without data wipe and everything seems to work fine. Games and apps that did not work before still do not work and ones that did still do.

Thanks for the great work on these roms!
[Teclast X98 Air 3G] sky|ined:
Almost as soon as I got the device in my hands I flashed Mirek's ROM but.. I run antutu before and after, 27000 vs 32500. That and the fact that a lot of Chinese bloat is gone suggests that the device became faster

Another update on compatibility. I can say with 100% certainty that mirek's v 6.0 ROM is fully compatible with my AIR lll android only device. I have no problems to report, I know I made a note about lagginess in a previous post and I have to explain. For £91 this is a good, satisfactory device and fast enough to perform every task - I don't play games.

I suggest custom ROM, custom launcher, and gravity (expanded desktop enough of a reason, amongst others)

[Teclast X98 Air 3G] mirek190:
You take partition table from folder partitions and replace the current partition.tbl in root directory.
[Teclast X98 Air 3G] mirek190:
In init.d you have to add script like

echo 640 >/sys/class/drm/card0/gt_min_freq_mhz

echo 640 >/sys/class/drm/card0/gt_max_freq_mhz

Editing 640 to 550 or lower to get the gpu stable ( 640 is default for tablet - I set up in my roms 580 mhz ) .
[Teclast X98 Air 3G] hedelein:
Hi mirek,

thanks, I figured it out after poking around for a day and forgot to update my post.

For some reason, Teclast has nailed the GPU down to 396 MHz with the X98 Air III Android 5.0 ROM, which leads to horribly slow GPU performance.

I set it to the maximum possible (646 MHz) and it runs very stable with these settings.

Any chance you'll update your 4.4 or 5.0 roms to run on the Air III?
[Teclast X98 Air 3G] rudnik8:
I installed this rom yesterday on my C9J8(came from mirek's 4.4 ROM), wiped data and im quite dissapointed. Maybe im doing something wrong, im not sure

ROM is not smooth at all. It seems worse than original teclast 4.4 ROM. Dunno why, i tested it without any apps and it was still bad. It's far much worse(for me) than 4.4 mirek's ROM. Virtual keypad is lagging a lot(stock and swift key), and when the screen turns off by itself, it flashes twice and then turns off. Like CPU was blocked on very low frequency or something

Battery is going down superfast, without any particular reason - i checked for wakelocks and there were no suspicious ones

I tried to move clock from middle to standard position in xposed and it crashed whole system(systemui crash over and over)... Had to flash it again
[Teclast X98 Air 3G] XICO2KX:
Great work with this ROM, mirek190! ;)

I installed it on my C8J7 model with BIOS 2.05b, but I have a problem...

Is there a fix for it?:confused:

Or do you have any plans to fix it in a near future? :fingers-crossed:

So i want to flash this Rom on my brandnew X98 G3 (C5J6) and i want to repartition it, so i use the MFT tool with the drivers install before. But dont work :( I use the xml with repartition, plug in my tab and.. nothing. The tab was in device manager but MFT seems not to see the tab.

Ok, then i use the .bat in the package to flash and tick point 3, but i only see "in Developmet yet"

Ok, so no repartition and use the full wipe flash. That work but after all the install , the battery was low and it plop up the "save energy", i tick yes and display goes totaly black. I hear sound from the volume wipes but cant see anything. I must plugin the charger and then the display comes back.

I know at my first charge (all stock W10-Android 5.0)), that charging stops at round about 8.100mAh but after flashing Mireks Rom, it stops at 4600mAh. Why??

Is it possible to use this rom on Air III ? or any way to root Air III ?? Please help!

---------- Post added at 11:24 AM ---------- Previous post was at 11:18 AM ----------

Hi hedelein! Can you help me how to root Air III?
[Teclast X98 Air 3G] hedelein:
Hi,

it's pretty easy, just follow this guide:

http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096

When asked which TWRP/CWM version you want to load, choose 5 (CWM)

When asked which trigger should be used, choose T4.

After flashing the SuperSU zip file and selecting Reboot System, CWM will warn you about losing root access, and asks you if you want to fix it. Choose “no” because otherwise CWM will overwrite the su binary that is included with SuperSU.

When your tablet has rebooted, start SuperSU to check if everything worked :)

Mireks ROMs do not yet work on the Air III as far as I know.
[Teclast X98 Air 3G] Koles86:
Thanks very much!!! It worked :) And one more thing. Is the xposed working on it also ? And if yes how to install it ?
[Teclast X98 Air 3G] mirek190:
On air 3 use rom for air 2 - works perfect .
[Teclast X98 Air 3G] XICO2KX:
Hi mirek190! :)

I've just used your Flash Tool v2.5 and it works fine! :D

But throughout the process, it shows some error messages when formatting the partitions, for example:

erasing 'system'...

formatting 'system' partition...
Formatting is not supported for filesystem with type ''.

It doesn't influence the successful completion of the flashing process, but maybe you should fix this one day! :p

Possible portage to X89 ?

Hi, i investigate to adapt this rom to the teclast X89. The hardware is almost the same as the X98 Air 2.

Minor changes are the screen resolution (only 2048*1536) and the touchscreen (smaller).

It's possible to flash the teclast x98 2.02 and the mirek190_rom_v6.0 boot without problem. Screen looks ok but the touchscreen is off (resolution missmatch).

mirek190 do you have some clue to adapt touchscreen resolution ?
[Teclast X98 Air 3G] mklmkl:
I've successfully flashed X98 Bios 2.02 on my X89. Currently I'm only using Windows (bought a partially corrupted device on eBay), Windows 10 activation wasn't affected by the X98 bios!

X98 Air III & mirek190 rom

hi mirek190 ,

Flashed rom ( only system.img ) today works much better than the stock one........really liked the Teclast stock launcher ( TOS / JuiLauncher ), so extracted it from original rom to use on yours.....in addition: as well on stock as with your rom when charging the Teclast the screen turns on and off every now and then , when turned on as well when turned off. Is this a bug in the firmware?. Does anyone else have this also?.

thanks

Weird question- on Techtablets forum there were some questions from people using Teclast x 98 pro- k9c3 or k9c6.

Mainly they complain on some Android booting stuck - on logo. No teclast support as you know exist.

Weird question is they could use any of Mirek Android roms to flash?

Air III 32GB Single Boot

Hello,

I use the AIR III with Android. I don't want flash the complete system, but I want the complete Google Apps like contacts, calendar, chrome and gmail. Can anyone give me an howto for installation of google apps. The installed google app doesn't include the sync for contacts, I think its not complete.

And I have a problem, sometimes when I switch the device one I'll see only the backlight (light up black screen with no icons and background) then I must switch the screen off and on then it works. Or when I press the button longer as normal then it switch also correctly on. Has anyone this problem? Or has anyone here the dualboot version of AIR III? When I make the bios update for dual boot, is it then necessary to install the windows 10 too? Or it is only possible.

summary:

- How can I install google apps for android 5 on this device

- How can I make the Update of the Bios for dual boot

The only thing I recognised, is the name of the camera in photos is now "X98 Air 3G(C5J6)" (instead of "X98 Air 3G(C5J8)"), but since I won't use the camera often I can live with that ;)

Mirek,

is it possible to add doubletap2wake in the kernel ?

I assume the power button is not so sturdy and has a shorter lifetime than those on expensiver tablets....

One has to press the button to wake up the tablet a couple of times a day, maybe 50 times

or even more...

That would be a major improvement if you just double tap on the screen...

Unfortunately there is also no light sensorm otherwise one could try this sview thing...

What do you and the others think ?

My battery life is pretty bad too. But, to be fair, I didn't try it much with Windows to compare it and my device is pretty new, 3 or 4 times fully charged so far.

How long does charging take for you guys? With the original cable and charger, with Android powered on but in stand-bye, is 4 hours still ok? I tried a different cable (from Sony Z3 Compact), with that one it told me 7 hours until full (from around 30%) :eek:
[Teclast X98 Air 3G] Meikun:
Yes I did it, and the problem persists. The battery starts to plummet after 50% has been consumed, then it falls down extremely quickly (5 or 10 minutes) until 20-15%. It's crazy and really annonying. It didn't happen when I was using the stock ROM.

Air III 32GB with iPad screen is ultimate budget model. 64GB model pcba was canceled. Air III is brand new tablet from factory using new casing. Intel is unloading all lower grade Atoms stamped at Z3735F which is just same cpu as Z3736F but with lower burst clock speeds aka. cheaper lesser quality chips from Intel fab. Teclast like all Chinese small manufaturers is not storing any mainboards or making those inhouse. They are ordering mainboards as they get sales and factory runs. Mainboards come from bigger "printing" house like foxconn (but not foxconn, maybe) They are just using cheapest chips Intel gives.

Intel will unload all Baytrail chips untill Cherry Trail replaces them.

Also last batch of Teclast X98 Air 3G ever to be made is produced almost fully. It is Z3735F with 3G but no GPS. After these tablets are sold there wont be more.

Reason that there is no 4G model of Cherry Trail tablet is simply price. The pcba has slots for it. For now Intel is asking too much of it and Chinese are waiting for price to drop. Too expensive chipset wont fit to Chinese brands *pricetag* or manufacturing budget.

......

Overall first Z3736F were unstable anyway so these are all same CPU:s just now undercloked abit.

Run it.

Go to superuser mode:

$ su -

Find the path of the file of original and new (for referrence):

# find / -name "SystemUI.apk"

List the existing permission of the existing file:

# cd /system/priv-app/SystemUI/

# ls -l SystemUi.apk

Copy the file and overwrite it:

# cp -rp /storage/emulated/0/Download/7*/*.apk . (syntax: cp -rp <source> <target> )

# chmod 664 SystemUi.apk

# ls -l SystemUi.apk

Exit Terminal App and Reboot
