If you 1st install the official rom like lrobberl suggest, u can also add the xml to only flash system so you keep windows and dual boot (and when you flash mirek latest rom you use the flash system only and delete data only xml and you will still have windows)

Im on c9j7 I flashed the new bios using the tool from official rom (from android itself)

here is how i did it:

YOU DO IT ON YOUR OWN RISK - im not responsible if anything goes bad

6. do the same thing as step one: but use one of the xml mirek added in the lollipop rom:

flash-full_with_pattitioning.xml if you want partition made again (erasing everything)

or

flash-system_only_and_format_data.xml if u want to only flash system.img and delete the data from android (keeping windows partition)

or

flash-system_only_no_data_formating.xml to only flash system without deleteing android data and without touching windows partition (not recommended)
[Teclast X98 Air 3G] royeiror:
Thank you.

I opened the file with ES File Explorer and most of the file is gibberish. Did I do something wrong?
[Teclast X98 Air 3G] mirek190:
Yes you did [emoji2]

You have deodex system ui then copy on computer use apktool to decompile apk and edit what you want then compile again in to apk and copy to system with persimisions 644.

OK, I read it.

So I assume, that BIOS 2.02 bin is OK for C9J7, so I will flash the same file, which I used in BIOS flashing (but do not know, which problem cause device brick, because whole procedure was completed with success).
[Teclast X98 Air 3G] dagrim1:
Think it's smoother (V2 at least, V1 had some issues). At least not as much bloat and chinese apps.

No clue about the camera, mine isn't working at all.
[Teclast X98 Air 3G] lrobberl:
Yeah... Mirek are there going to be any fixes in future for the camera? Mine on C9J7 with V2 ROM doesn't work either.

Does your camera not work at all? Or black screen? Or upside down?

lollipop deodexing

mr mirek190,

i am loathe to take your attention away from your very fine and much appreciated modding, but... :)

can you recommend a nice free android app that will deodex the lollipop systemui.apk?

i started reading on how to do it on xda and my eyes crossed. :| i would love to clean up the navigation bar like you did in your kitkat 3.1 rom.

to anyone who knows,

is a usb hub absolutely necessary for windows install?

i'm trying to install win10 on a c9j8 that currently has no windows installed (it dual boots). i have a usb with the latest win10 public build (10130?) formatted fat32 uefi in rufus. i plug it into the usb jack on my teclast, boot into win part and up pops a blue screen with language settings (a rather tiny window!). it says to hit next to continue. touch does not work. i unplug the usb stick and plug in keyboard, no response. i read the "normal" methods about using winpe zip and two usb sticks in the first part of the thread. i was kinda hoping to cheap it out and not spend $6 for a hub.
[Teclast X98 Air 3G] Chur2Much:
To install windows 10 you need a USB hub because the files need to be read from the USB for installation and keyboard and mouse to go through the setup
[Teclast X98 Air 3G] lrobberl:
Looks like any camera apps (the stock one and the Google Camera) dont load the camera... You know, it stays still with the camera logo as it tries to load it.

Nothing happens though, no crashes or stuff like that
[Teclast X98 Air 3G] mirek190:
For the time being the camera is working only on C5J6 as far as I know.

I try add drivers to the kernel from 4.4 maybe will be works ....

---------- Post added at 01:33 PM ---------- Previous post was at 01:13 PM ----------

You have to use a computer to make any mods on apks. Apktool .

I'm sharing my yesterday work.

Just replace systemUii.apk and framework - res .apk with privileges 0644.

If you don't do that then android go into bootllop.

Hii mirek190

in the 1st i thank you for the lollipop v2 is very smooth :good:...

in the 2nd i have some reports in v2:

- users setting missing

- bugs when using Dolphin browser

- button " clear all" missing in rcents panel ...444 have this button

- camera off course but i know this is a driver problem:D

this is my reports

in the other side for SystemUI can be integrated in the futur as AOSP or CM based rom :confused:

finally i thank you so much for your efforts:good:
[Teclast X98 Air 3G] kapi:
C8J6 here without bios updated (afraid to brick) everything work with L vers2 even Cameras (back have a problem with focus). Google + can't install even tried Apk. Seams to drain normally when use, i shutdown everytime, so it's not a problem for me. Flashed with fastboot (flash, erase) command each Img cause i can't get Manufacturing Flash tool to recognize the tablet (may be a windows problem), but it's fine and more simple to use fastboot for me. Great work

Mirek v2 - Multi user

Today flashed to mirek's v2 rom on my android air II, works perfectly except for one thing. Does anyone know how to get multi user running? The option isn't available in the settings menu and when clicking top right user icon it says contact not found. Anyone knows how to get it back?
[Teclast X98 Air 3G] kostas-k:
I faced a strange problem today with my C8J7 today. The battery was at 12% when I shut it down to plug the charger. The charging battery icon showed up and after 10 minutes removed the charger and tried to power it up but with no luck. Pressed all three buttons simultaneously, after that Power and Vol+ and at last Power and Vol- but nothing. Tried another charger but nothing also.

Any solutions?
[Teclast X98 Air 3G] mirek190:
Restart the tablet . .then will be OK .

---------- Post added at 03:07 PM ---------- Previous post was at 03:03 PM ----------

Very easily - just keep power button around 30 second.

I had only ocne that problem few months ago.
[Teclast X98 Air 3G] lrobberl:
Tried to restart but no luck...
[Teclast X98 Air 3G] royeiror:
Thank you. This makes everything a lot easier.

EDIT: I can't open the file either in my windows PC or ES File Explorer. It says it might be damaged.
[Teclast X98 Air 3G] mirek190:
That's strange .

I had such problem then just keep power button for 30 sec and started - mine friend had that ptoblem as well - he did the same thing and works.

switch apk?

I've been looking for the "Boot to Windows" apk from android that I see in Mirek's new rom (icon) is it available some where...I have the boot to android from windows exe...could you please point me in the right direction...thanks
[Teclast X98 Air 3G] elvisi:
Hi all,

First of all congratullations to mirek for his work, your roms are simply the best. Thank you very much for it.

I have an air II tablet (HG7N),and I have some issues with mirek's 5.0 v2, performace it's great, antutu results are really good, and 3d games perform well (look attachments), but when I play star commander (2d retrolike game) it's terrible, a lot of frame drops (not happeing with KK). I've tried with gpu acceleration on or off, but it's the same. Does anybody find something similar? Also instagram app is not working, neither the camera (doesn't really matters to me), and sometimes notification bar blinks (while in telegram for example).

On the other hand, wifi is better than ever.

P.D.: ¿Does anybody tried 2.01 bios in this model air II (HG7N)? Any idea where to find it?
[Teclast X98 Air 3G] johanw90:
please help me.

i tried everything to update my bios,

with updateifwi it keeps saying upgrading this may take a few minutes.

with the flasher i get this

usb debugging is on
[Teclast X98 Air 3G] skew:
I just updated my C9J6 64gb to 2.02 with android flash everything went smooth no brick. But my Windows sleep battery drain is still there maybe not as bad 4-5%hr so far. I may try and install windows 10 to play around with and see if I still have battery drain.
[Teclast X98 Air 3G] kkoops:
How did you save your licence and do you have to restore it into the 2.02 BIOS?

Thx in advance.
[Teclast X98 Air 3G] whiget:
I had the same problem. Double click on flash.bat. run it NOT as administrator. Works for me :)
[Teclast X98 Air 3G] Wootever:
A licence restore is most likely only required if you completely erased the bios chip before, but it is always recommended to create a backup.

Here is a small msdm backup package:

http://www6.zippyshare.com/v/xogyQ7rV/file.html

Open OAKey.exe and click on GetOAKey, it will read the acpi table and create a file named oa3_fixed.bin containing your windows serial number.

Now - if you have erased your bios chip (in cases of a brick or to avoid mismatches from previous bios versions) you can restore your licence by clicking Restore.cmd [running as administrator].
[Teclast X98 Air 3G] johanw90:
thankyou it works now! flashed with succes.

[Teclast X98 Air 3G] muzetas:
I had the same problem. First try to leave it charging overnight if it didn't help the only way is to open the cover lid and dissconnect red wire from battery for around 1 min and then connect it again. The second solution helped for me. I know that is hard to do that but it's the only solution I have found in the internet.
[Teclast X98 Air 3G] lrobberl:
I googled "extract windows license bios", and I found different links... I'm afraid I can't give you the exact link cause I visited the site with my pc but now I can't check it.

Anyway I just saved the key but I'm not sure I'm going to use it, cause I don't want bing version...
[Teclast X98 Air 3G] billquinn1:
I flashed lollypop with no problem. Couple of small issues (no camera and rarely some odd screen flashes. CPU temp app won't run.)

[Teclast X98 Air 3G] juaaslo:
One different question maybe Windows users can help with!!

The HDMI output for windows, doesn't adjust perfectly to the size of TV. There is a piece of screen not showed, like the desktop doesn't fin in the TV. I have always worked with ATI drivers and there is a way to change this overlay. In android you can also adjust manually "zooming" so the image fits perfectly the TV. But I can not find any option in Intel HD sofware in the tablet. I can not believe Intel doesn't offer that option....so anyone knows what I am talking about and knows the answer??? :)

Thanks in advance!
[Teclast X98 Air 3G] jakep_82:
Works perfect on mine. This is probably an issue with overscan on your TV, and not the tablet. Check the settings on your TV. I had to adjust mine for 1:1 scaling with no overscan.

[Teclast X98 Air 3G] Lancer12345:

[Teclast X98 Air 3G] TomaszD84:
I also have this problem and I did upgrade the BIOS to 2.02. It's not very visible, but it does flicker (e.g. in GMail).

I would also like to confirm that with BIOS 2.02 the connected standby battery drain is gone. 7 hours of sleep consumed 2% of the battery. This tablet is finally usable with Windows without the dumb "hibernation" hacks.

I know I'm repeating myself here, but this thread has become insanely unmanageable and people are probably flashing their BIOS without thinking, so here goes again:

Flashing your factory installed BIOS will irrevocably wipe the embedded Windows key if you have the dualboot version from factory. So if you flash your BIOS and reinstall Windows with Bing (if you find the leaked ISO), it won't activate at all, so you'll have a "pirate" copy of it. Part of the price of the dualboot version is the Windows license, so I'd be pretty pissed if I lost it.

You can inject the new BIOS image with your Windows key if you still haven't flashed your BIOS from factory (otherwise it's too late) using this utility https://mega.co.nz/#!0I0zlDCS!PSrdxHDoHbsPJ9N7U-ajRR5vmB9qCI2xLuaPEFx-gGs and Google Translate using the visual options (app is in Chinese).

You can also dump the Windows key to clear text and save it somewhere safe, you can then manually activate the Windows installation if you wipe it. Search for an OEM: DM key dumper.

thanks for the additional info.The rar file on Techtablet is indeed corrupted but then I got a proper one from the french server you suggested

To make things completely clear in my little head,refering to what I highlighted below,you mean ANY mirek rom would do even old ones or you are suggesting the latest ones aka lolipop variants?

as I mentioned,I would love to keep my windows partition as it is and the dual boot as well

Safe Flash - in Android

1. Install Stock ROM 2.00 official firmware ROM "X98 Air 3G (C8J7) Android 4.4.4 V2.00 (Official Rom) (556.1 MiB)" is found here (flashing an official rom so u have/can use UPDATELWPi apk)

http://techtablets.com/teclast-x98-air-3g/downloads/

if you dont want to erase windows partition,

get installer-system_only.cmd and flash-system_only.xml from one of mirek's rom

and paste them in the official rom folder (where there are the .img) and in intel flashing tool use flash-system_only.xml instead of flash.xml (i removed it from mine)

(if the rar is corrupted then you will have to download it from somewhere else (had this problem), you can try to download from here: http://dl.free.fr/jgJWxiAig (thats where i got it)
[Teclast X98 Air 3G] Nuja:
I took them from: "X98 Air 3G (C9J7) mirek190_v3.1"

I flashed the bios (from factory dualboot x98), didnt touch windows partition (didnt redo partition structure) and my windows is still activated but its still a good idea to make a backup of the windows key.

Btw aint our tablet getting win10 free upgrade ? got this on my personnal computer but no sign in the tablet.
[Teclast X98 Air 3G] TomaszD84:
That was not what I meant. You will not lose your current activation if you flash the BIOS, you will however lose the ability to activate Windows if you need to wipe it and install it again...

Touch Screen Problem - Android (boot.img!!!)

Hi Mirek190 ...

from me too... thank you for your great work.

I have the same problem as "zvenzzon".

My touch screen (Teclast x98 3G 64GB (C8J6)) operates under Android only with the special "boot.img".

This "boot.img" works only with the original Teclast 4.4.4 Rom and with the Chinese Lite 4.4.4 Rom.

With Your Lollipop versions the touch screen do not work and with the special "boot.img" the system will not boot.

I hope you find the time to program a special "boot.img" for your lollipop versions.

Thanks in advance ...

Thanks for answering!

I haven't found any option on this TV nor other TVs related to hdmi overscan. If you never faced this issue I think you are lucku! For every TV I have ever connected to my laptop, I always needed to use ATI tool (Catalyst) to adjust size of image in secundary monitor to screen size. And particulary in Teclast, if you consider Android, you also have the possibilioty to adjust it. I cannot believe Intel HD misses this option on their software, there must be a way to asjust for Windows also!

Every TV I've used in the last 10 years has zoom/overscan settings.
[Teclast X98 Air 3G] royeiror:
The x98 Air II thread has little to no movement compared to this one, but am I correct in guessing that the BIOS files are specific to each device? I have a HG9M 64GB Air II and don't have the flashing device in case I mess it up, so I need to be sure I can fiz whatever I mess up.
[Teclast X98 Air 3G] juaaslo:
Yes, you can use zoom instead of default 16:9 aspect ratio, changing it manually. But I think the best option would be adjusting in source, using drivers or configuration options, so you don't need to change tv configuration depending on the video source. I don't know, maybe it is normal behaviour in Intel software for windows and I am just used to do it other way around. But it is still weird for me not to have those scaling options in Windows for Intel card, when they are available for Android and ati cards also in wondows computers.

Anyway, thanks for interest and comments!

[Teclast X98 Air 3G] Hendrickson:
Nice one! The fix for people that seem to have slightly different touch hardware. Remove the Touchsetting.gt file in C:/Windows/inf reboot and the touch screen is not reversed. :) Only do this if you have applied the camera fix and your touch screen is messed up. It seems there are a few of us that had issues. Most people shouldn't have to do this.

Also a tip for your emulator or old games. If you want 60hz in lower resolutions, try this.

Windows + R then type CustomModeApp and enter the lower res and refresh rate you want and try that. CustomModeApp only works with the old intel camera fix drivers.

[Teclast X98 Air 3G] keepfishes:
Hey guys,

Anyone noticed high battery drain in Win 8.1 when the tablet is put into sleep mode (connected standby)? As compared to Android with screen off (not shut down), the drain is extremely high for me, up to 2% drain per HOUR.

Thus, I have done several tests on Windows and found:

1) Flight mode ON, Wifi OFF, Sleep 3 hours

3 hours of sleep consumed 5% (1822 mWh) of battery power!

The sleep interval time is 32 seconds, which is normal. Top 5 offenders says that nothing is consuming power! I don't know what is causing the power drain!

2) Windows reports that I have estimated 10 hours battery life when using, but only 50 hours of connected standby time! And drain rates are extremely high at >25% per 16 hours, the ideal figure as stated by Microsoft is 5%!

3) This is not a one off problem as you can see, my tablet has not been sleeping properly:

Anyone has experience the same issue as well? I see many users of other Win 8.1 tablets having this problem, but so far no one in this thread has mentioned this problem... So far I keep having to shut down the tablet to prevent power drain, which is quite annoying!

To get the graph and data, run command prompt:

powercfg /sleepstudy

AND

powercfg /batteryreport

Thanks!
