It's possible also for M5C6 (64Gb Dual boot) [emoji6]? Or we can use the file from 3G?

So it's for M5C5 not for C5J8?

Just use for that c5m6 ( I think they are the same )
[Teclast X98 Air 3G] mirek190:
So c5j8 has a problem with the camera too ?
[Teclast X98 Air 3G] NicodemPL:
It works in camera app but not in Skype. Skype - only front camera

[Teclast X98 Air 3G] mirek190:
Ok give me orginal c5j8 kernel ( boot.img ) I check it .
[Teclast X98 Air 3G] SkubiDoo:
Please maybe first check M5C5, because still only front camera works in Skype :(

I've just checked boot.img from 2nd post and still the same issue.

Let me know if you need more details from M5C5 I will share with you.
[Teclast X98 Air 3G] blackbile:
Mirek - there is very questionable thing in your 7.0 package - the BIOS update, I read here and saw in the package, that you use for flashing the 2.05b version, so maybe that is a big trap for the C5J8 owners, as there are 2 people who reflashed the BIOS with your tool and his tablet bricked!

I think for C5J8 the perfect and ONLY USABLE BIOS is 2.05c version!!!
[Teclast X98 Air 3G] Furdik:
Hi, what you think, which bios is the best choise for C9J8?
[Teclast X98 Air 3G] ZeekWorld:
Mirek,

I have a c5j6, came preloaded with dual boot Win 8 and Android.

I would like to start from scratch and keep Dual boot with a fresh copy of Windows 10 and your Android Version 7 Rom instead. Can you let me know if there is an updated link to perform this full proccess please.

I would like to see a step by step to guide me through the full installation Win/android dual boot fresh install.

Note: I've already updated the bios on my c5j6 to 2.02 some time ago.

Thanks a lot in advance.
[Teclast X98 Air 3G] mirek190:
Is the bios 2.05c works Ok on other devices ?
[Teclast X98 Air 3G] blackbile:
Unfortunatelly I don't know.
[Teclast X98 Air 3G] Gitanitos:
Hello mirek190, I unblocked my tablet X98Air III "M5C6" with the files from blackbile' post "Unbrick X98 C5J8 (pionioni method)". In this post, blackbile said that BIOS were 2.05c.

At this moment it works but if I shutdown from any OS, I can't start again. I need to push +10s power button, after that, it start again...I don't understand.

Do you have any idea of this kind of behaviour? I have really fear if I need to flash again another BIOS [emoji37].

[Teclast X98 Air 3G] blackbile:
do you remember that it started good before bios restore??? As I answer you earlier that is "normal" behaviour - I think.
[Teclast X98 Air 3G] Gitanitos:
I wanna think yes but I don't remember (maybe I needed to do this one time).

The only thing is that in this state the tablet is draining the battery, I checked this evening.

Hello. Which version I must download for AIR 3? X98_Air_2_android_5.0_mirek190_v7.0 or X98_Air_3G_android_5.0_mirek190_v7.0 ? My bios version is 2.05.
[Teclast X98 Air 3G] picarddontoro:
Hi to all. I own a Teclast c98 Air (C5J6).

I flahed bios 2.05 (from 2.02) and right after mirek190_rom_v7.0 (from v.6.0).

At this moment if I shutdown from Android, I can't start again. I need to push +10s power button, after that, push again power button and it starts. Moreover, I see a significant battery drain when the tablet is off. It seems that the power off (from Android) does not really closes the tablet.

If I shutdown from Windows all is ok. I have to reflash the previous bios 2.02 or Mirek190_rom_v6.0? Can anyone give me a solution?
[Teclast X98 Air 3G] Gitanitos:
Hello gthebest, You have only one version for all variants. I flashed in Air 3 (M5C6) and work fine.

PS: Could you please say me if do you have the same issue than us (when I shutdown the tablet, I can't start and I must press power button +10s). Thanks for your answer

Enviado desde mi SM-G900FD
[Teclast X98 Air 3G] gthebest:
I have air 3 M5C5 not M5C6 is that a problem? When you say one version then why there are 2 rom versions air 2 and air 3G? Which one I must choose? The issue you say is with the factory rom or with the custom and which version of all?
[Teclast X98 Air 3G] takagen:
I confirmed i've encountered the same after flashing 2.05.

After several attempts to boot back up into Android, i have to flash just the bios 2.02 to resolve this issue.

Mine is a HG9N.
[Teclast X98 Air 3G] Gitanitos:
You have two versions (standard & ultra light) of the same ROM V7 that is for all variants.

Use the guide as described by Mirek190 in the first post, it's really easy.

The issue usually is when you flash a new BIOS over stock.

Enviado desde mi SM-G900FD
[Teclast X98 Air 3G] gthebest:
The issue is the same with all the firmwares (7.0 6.0 5.0...) ?
[Teclast X98 Air 3G] Gitanitos:
The issue is not from firmware, is related to BIOS version or flashing a new BIOS.

[Teclast X98 Air 3G] Barleyman:
2.0.2, I was following Tecknight's tutorial.

Trying to get the 31.8. lollipop from Baidu, fun fun. You're supposed to be able to use the accelerator with weibo account but in practise this does not seem to work.

Service has been temporarily unavailable (from the download spyware backdoor software) all day on that. WRT registering for baidu directly, it's tricky as they want you to recognice phonetic chinese character and online dictionary's ideograms none look like the available choices.
[Teclast X98 Air 3G] Barleyman:
Well that could have ended in tears. Seems like all of the necessary drivers are unsigned so if you don't do custom reboot to disable driver signature enforcing, nothing works.

You can still use Mirek's "android way" flashing but I was careless with editing the batch so I had it erase the partitions without actually flashing new firmware. Ouch. Well, disable driver signature enforcing and manually install the ADB and SOC drivers and MFT tool starts working. Now I've got shiny new PRC X98 64GB dual boot lollipop mark 31 August.

Nope, Kindle does not work :)

That's enough effort, I'll go back to Mirek's v4.2, hopefully that Wifi problem I saw last night is not a recurring feature.
[Teclast X98 Air 3G] Barleyman:
Looks like the v1.5 Intel USB drivers (comes with Teclast firmware etc) are not signed but the Knight's v1.1 drivers are. Who said newer is better?

I wonder where the Android ID for Knight's MFT ini file comes from. Teclast says to use 0FFF there.

If we could get a Kindle fix on top of the other fixes, that'd be doubleplus good.. Google+ is another app teclast broke with lollipop, it seems to work fine on Mirek's v4.2 Kitkat ROM.

.. Oh and about Baidu.. It seems if you fail the captcha test, it locks you out but you can request password reset and then it's all OK.
[Teclast X98 Air 3G] mirek190:
Ok - thanks for feedback .... I try to do something with it ...

Is Kindle running OK in Mirek's 5.0 ROM?

Hi,

I just bought a X98 Air 3g (C5J6), and although it had to come with 5.0, in fact it came with 4.4.4. I'm thinking on upgrade it to 5.0 before installing and saving stuff, and I'm planning to do it with Mirek's 5.0 v5 Rom, because it seems to be the best today. But I would like to confirm that there is no problem with Kindle application as Barleyman states...

Any news about it?

I don´t have this Problems with mireks rom V5 as an example. With this rom you don´t have the camera, but nothing other problems.

The "Throttling brigtness due to thermal event" is a normal problem on the stock rom. You can edit you thermal event xml (thermal_sensor_config.xml ) and change the values. Then it shouldn`t happen anymore.

[Teclast X98 Air 3G] Araneo:
I have issue with battery after installing this lolipop v7.0

I was on Mirek's 4.4.4 rom and wasn't battery problem at all.

I installed this lolipop v7.0 with Mirek's flash tool - I used wipe data.

Now the battery working well from 100% to about 50% capacity.

From 50% the battery droping down very fast (even the screen is off). It takes about 1-2 hod to drop down to 2%.

When I start use tablet on 2% it switch off after about 5 min - so it is not battery meter problem.

I have C8J6 with 2.02 bios.

How I can figure out what is the problem? How I can solve it?

The battery is draining pretty fast even with screen off on Lollipop. I don't remember if that was the case with KitKat, but I have a feeling that the battery lasted a lot longer when idle on RemixOS based on 4.4.4.

Hello and sorry if my English is not the best.

I have bought a Teclast x98 Air III and I'm going to flash your rom, but I have a doubt.

The instructions to flash the Rom are clear but I have to install also the Kernel (boot.img) which makes to work well the camera and I don't know how.

Do I have to substitute the file boot.img that is in the folder ROM for the one you can download apart for the M5C5 before flash?

Or do I have to install first the ROM and after the kernel?

And is know that are 2 versions of Air III, M5C5 and M5C6, so the kernel is for both or will not work on M5C6?

Thank you.

How to fix battery life on this ROM? I came from official debloated lolipop, and on mireks 7.0 i have very bad battery life

Tested on mine with skype again for 5mins, switching the cameras works :) Had one hickup (video froze) but with a camera switch it's back on. When I put skype in the background video will be transmitted, but the preview on the tablet is stuck with a green background. Putting skype in foreground and switching cameras and everything is back to normal :)

Regarding the modded boot.img for m5c5 from post #2: Have you tried clearing the cache or formatting the cache partition after flashing the boot.img? I started fresh with the correct boot.img then...

Just try "fastboot.exe erase cache" with the fastboot in mirek's rom package. Can't test this right now because the fastboot on my linux boxes doesn't seem to work with the tablet :confused:

---------- Post added at 05:09 PM ---------- Previous post was at 04:38 PM ----------

I looked at the batch file from mirek. If you have installed the boot.img via Option Key K the cache is indeed not cleared. So if you want to use fastboot you have to do it like in the script

fastboot flash osloader ROM/efilinux-userdebug.efi
fastboot boot ROM/droidboot.img

Or just edit the batch-file and reflash the kernel with Option K. Place "%fast% flash erase cache" before "%fast% flash boot ROM/boot.img". (around line# 100)

Hope this ain't all bollocks and it gets you forward :)

Flashing v7 over 6.1 without losing use profiles

Hi community.

Can someone more skilled contact me on PM regarding this? I'm not an android flashing guru and don't know which data are stored in which location.

I flashed mirek190 Lolipop v6.1 over original 4.4 just on 24th of December :)

That was simple because I didn't preserve anything. But now I would like to flash v7 and keep my kids' profiles (with their games and progress).

What are the options? Just pick up specific option while flashing or use special app that can backup application together with progress?

Is there an microsd card startup script on this ROM? I've tried different cards, as well as card mount apps, to no avail. The notification tray indicates that I can safely remove removable storage when I insert a card, but nothing shows in Storage (in Settings) or any relevant apps.

UPDATE 01/26/16: So it's not the ROM fault, but the fact that I was using a card not supported by the X98. When I reverted from a 64GB microSD XC to a regular 8GB HC (the only other card I have to test), things were rosy again.
