Lollipop v3 working GREAT here, congratulations mirek! I trust you'll solve the camera issue in next builds :)

About the windows part, I keep running my windows 10240 fine, with only 2 issues: front cam not working (same as other people I read here) and touchscreen driver could be better...

As stated before in this post, I've found 3 different touchscreen drivers. The oldest one (the one which comes in the cam fix) is super smooth but half screen is reversed and I couldn't manage to fix it. The second one is terrible slow, and the latest one (the only one which is properly signed) works just OK, but not as good as the oldest. Anyways, I've improved the touch smoothness by setting to 0 the friction value in Windows registry.

About the camera, it's odd somebody told that same camera is described as different depending on the dual iso version you flashed. Since I'm using the latest (2.0.2), would I get the front camera working if I flash an older dual bios? For me, front camera is more important than the rear in tablet cause of Skype, etc. Can I flash other dual bios without having to start from scratch the whole process (I mean installing official rom, reinstalling windows, etc) ?

Thank you so much for your help. I remember my teclast is c6j6 hardware version.

Edit: I also miss exfat support in Android.

Vainglory does work on the stock 4.4.4 rom and also shows as compatible due to being able to download directly from the play store, lollipop v3 it does work with though so thats good. The biggest problem is the screen dim message every 5 mins on lollipop v3, personally waiting for your lollipop v4, dont spend too much time on 4.4.4, most people want the latest android version anyways :)
[Teclast X98 Air 3G] sahor:
OK, Then I am going to flash your Lollipop Rom if you recommend me. I have Air II HG9M dual boot 64 gb. Should I flash v2 or v3(¿beta?)? Both have cammera issue?

Can I use this flasher to flash an older dual bios version? I'd like to check if my front camera works with other bios version in Windows (c6j6, there's no way to get it working with bios 2.0.2). How can I check the bios version number before flashing? All seem to have similar names...
[Teclast X98 Air 3G] siezed:
Flash v2 and let me know if vainglory stil' does the message every 5 mins :)

---------- Post added at 12:39 PM ---------- Previous post was at 12:35 PM ----------

They should all work on airii its basically the same tablet, i know for a fact v3 works as ive used it on my hg9m air ii, i might try v2 next if you dont just for vainglory. note the only issues are camera might not work correctly and the hardware reporting is wrong, it will say you have one of the cj models, but you can manually edit that in build prop if you really want to.
[Teclast X98 Air 3G] sahor:
In order not to take risk I will wait for one specific for air 2. While I am on stock ROM and it is usable but maybe could be better. I don't like so much lollipop 5.0.2 in my OnePlus one, and for that I prefer 4.4.4... (maybe 5.1 would be better) I'll wait for next v4.1 for air ii.

[Teclast X98 Air 3G] siezed:
well i mean mireks 4.4.4 v4 does have an air ii file, if you want one specifically named for it, but i mean a lot of us have flashed the v3 lollipop and confirmed it works fine so i think the risk is minimal at most. Also the v3 lollipop technically has an "all variants" file, and is made to work with them all. The v2 may bea a risk, i havnt actual'y looked at or seen if it has an all variants version, but as far as i know this tablets variants are all just harddrive size, dual boot capability and 3g/wifi module.
[Teclast X98 Air 3G] mirek190:
Flashing bios is not working yet - in v3 will be working - can someone post bios 1.07 or 1.09 ready to flash - I think add options to flash 3 biosess or even more like only android and only windows as well but need all that biosess ...
[Teclast X98 Air 3G] juanmaasecas:
In techtablets.Com repository there are plenty of bios, are they all the same so? I'll try to flash another one, I think I read in the past some people with both cameras working (reversed, but now we know how to fix...) ... I'm not worried about the apps to switch from Windows to Android quickly (and viceversa) but I do about the front camera not working (or the 48hz refresh date in some models in some older bios...).

I'll post my findings.

need help

i have some issue with my air 3g (C8J6)..

1. I tried to charge it and it sometimes managed to charge but there are no sign charging sign. I think its the same issue from a few users here.

2. In android mode, when i connect a cable from my PC to the tablet with developer mode enabled, it doesn't recognize it (i even tried in my linux desktop)

3. in DnX mode, it recognize the tablet but seems to have some issue while flashing in droidboot..

any solution?

i managed to flash bios 2.02 using windows though, luckly nothing bricked, but battery seems improve a bit..
[Teclast X98 Air 3G] tecknight:
I agree 100% with seized on this.

All of Mirek's Lollipop ROMs are for All Variants, and they have proven to be just that.

There is no risk in flashing a ROM anyway---Even if the ROM completely froze up and refused to boot, there are multiple ways to flash back to the previous version. The real risk is when flashing BIOS.

Seized,

I am on V3 and have never even seen this dimming message you are talking about.

When do you see it and what does it say ?

Does it actually dim the screen as well ?

I have had ZERO problems or complaints about V3. To me, it is Mirek's most stable, fastest and smoothest UI.

When playing vainglory i get the message very frequently, probably every few mins, it doesnt actually dim the screen it just shows a message like "dimmed screen due to device getting hot" its not the same message as stock roms message which says thermal event, i just figured mirek changed the message to be clearer to non native english speakers or whatever.

If you are not having that issue, then boot into Android and connect your tablet to a windows PC.

Go to Windows Device Manager on the PC.

Do you see the tablet at all ? as an unknown device or anything else ? Try unplugging and replugging

while viewing Device Manager if necessary.

FRONT CAMERA WORKING ON WINDOWS!!! C6J6

I just downloaded the file called "dualboot bios tested for c6j6 and c8j7" from techtablets repository, and rename it to be equal as the bios downloaded in the mirek's and tecknights packet. This bios version is 1.03. It could be fine if we make a list of what bios version is every bios file, it's a mess...

with the latest flash given by teknights, I've been able to downgrade the bios succesfully (tablet connected in Android Mireks v3 beta version) without repartition. After booting to my windows (everything unaltered) I've been able to make the camera work simply installing the driver. It's GC2235, not the OV2680!

Anyone wants to try other different bios version? I know that 1.04 exists, don't know how many differents so...
[Teclast X98 Air 3G] tecknight:
So you just want to supress that message ?

Also has anyone got viper4windows working? doesnt seem to do anything for me, i just really like the way the tube emulator sounds on my oontz angle plus, really takes the sibilance, or harshness out of it if anyone knows of a similar free dac that works id be willing to try as well, dfx also works great but they want like $30 or w/e to remove the popup message every 10 min.

Hi Tecknight,

when you said V3, is KK or Lollipop beta v3.0 ? :confused:
[Teclast X98 Air 3G] siezed:
he means lollipop v3, kitkat v3 is outdated and not really needed for anything as mirek has released kitkat v4, lollipop v3 is the latest lollipop from mirek though.
[Teclast X98 Air 3G] tecknight:
Yes, you are right. The BIOS images available out there are poorly documented, if documented at all.

Did you try the GC2235 driver with BIOS 2.02 and it did not work ?

---------- Post added at 07:53 AM ---------- Previous post was at 07:49 AM ----------

Mirek is working on full viper4android functionality currently. In fact, I think he has it completely solved and only needs to test. It ends up being a pretty complicated permissions issue requiring some boot time filesystem ownership mods to make it work fully. I can tell you from personal experience on my previous Chinese tab, viper4android is a game changer when it works.
[Teclast X98 Air 3G] juanmaasecas:
Yes, I tried the exact same driver that is working now in 2.02 bios, and didn't work there. If only we could modify the latest bios to inform that camera is gc2235 sensor and not the OV one, at least for c6j6 version of the bios...

As mirek said it looks fine : did you copy all the rom files to the rom folder (the one which is located on mirek flash tool). If yes just flash, and follow what's on the flash screen on your computer (not the tablet).

If you are stuck choose 2 reboot then you should have the usual dual boot choice : choose android and you're good to go !

device gets confused with wifi/3g to the point that it indicates 3g data is disabled but it still downloads over it and not WIFI, which is enabled?

This has happened for me since the ROM was released, and it was installed with a full wipe. I didn't report it before now because I thought Mirek had stopped development, but I see now you'voe got a 4.1 update on the way. I've been away for a few days, else I'd have written this earlier. :D

Mirek V3 boot.img installer-Supressed Thermal Messages

Supressed Thermal Messages on Mirek's V3 Lollipop ROM

This is a modified boot.img and installer

Download archive here:

Supress Thermal Messaging Installer​

1. Extract archive to a Folder on your Host PC (with ADB drivers installed)

2. Connect X98 Air device to Host PC using USB cable.

3. Ensure USB debugging is enabled on tablet. Settings->Developer Options->USB debugging needs to be checked.

4. Browse to the Folder on Host PC where you extracted Archive and launch SupressThermMsgs.bat

5. Once it detects your device you can press a key to proceed

The script will now copy a modified boot.img to your boot partition.

The script is very fast. When complete, press a key to reboot your device.

The changes in this boot.img should supress messaging regarding thermal events.

Post your log to XDA developers if you have questions.

Sahor,

The green battery you describe is "normal" behavior for your device when a charger is connected.

I don't like it either, but it's not a flaw in your device

Try disconnecting the cable and then reboot droidboot.

If the OS Select screen comes up, select android.

It should boot to droidboot

Bios and mod rom on c5j6

Hello, I'm trying to understand how to manage my device since I only find instruction for other release (c6j6 and others).

Questions:

My device is c5j6, dual boot 64gb, do I need to flash a new bios in order to change the room with a custom one? If yes, where can I find the right one (I don't want to brick my new toy) and how can I flash it without risking to delete Android or Windows.?

Are there other reason to update the bios?

Are there any custom rom for c5j6?

That's all for now, hoping that c5j6 is not a blocked device ?
