Hi,

My x98 3g doesn't boot anymore. It shows very short the ami-boot-logo with 4 lines oft error messages. It's almost the same as starting on low power. The difference is, on low power the message apears much longer. My screen shows up really short. The battery is full - no doubt.

Pressing vol + and vol- and power enters fastboot.

That happend after successless win10 update with win10 setup on the sdcard. I tried this update several times before the same way. Well, because of the update failture, wich is probably based on strange Hardware, i tried to disable some features in the BIOS. I set there an Option to Fastboot, then i disabled PS2 support. I dont think thats the Problem, because several reboots where successfull.

So, anybody an idea?

I have the same issue on my x98 air 3g. After change from Mirek to stock android, Windows icon disapered from boot menu. When i try boot into "boot to Windows" (after come back to mirek's rom) from android it shows like on your second screen.

I haven't found solution do far.

You have to reinstall Windows. Stock Android rom from Teclast deletes and reformats your Partitions.
[Teclast X98 Air 3G] giupa87:
any help for me?
[Teclast X98 Air 3G] Cozla:
I have installed stock rom with modified file. Android partition size is still the same.
[Teclast X98 Air 3G] SN1P3R-14:
It's the same but the windows partiton is empty and unpartitioned.

If you run a Windows installation from a usb drive you can see there are only 15 partitions instead of 19.

38000 MB should be unpartitioned and that's the space for the windows installation.

I also went from mireks rom to stock rom. My windows icon disappeared too. After that i plugged in an USB hub with mouse, keyboard and the USB installation drive for windows and installed windows in the unpartitioned space. After the installation i rebooted my tablet and it showed both icons.
[Teclast X98 Air 3G] Mikha777:
Download Win 10 32 bit edition ISO from Microsoft

Copy the ISO file to a USB drive with RUFUS using MBR Bios/UFI and FAT32 option

Plug the USB Drive and Fire Up you X98 and press "esc" to go to the boot menu and boot from the USB drive.

Follow the instruction to install Windows.

Happy with C5J6 and Mirek V6

Hi everyone, new here on this forum. Just got my X98 C5J6 model and am quite happy with it especially after upgrading to Mirek's minimal ROM Lollipop V6. That is an excellent improvement over the stock rom, and using his batch file straight from Android with reboot makes flashing a breeze. The method using MFT is more complicated and in my case did not even work.

Anyway I sometimes am puzzled by the genius designers that make these tablets and phones and decide to put so much crap in the stock ROM that the product is barely usable. If you do that too bad but let he user/owner fully debloat it so allow crap to be uninstalled such as in Windows. E.g. CleanMaster nice program but in stock rom you can not remove unless rooted. And which international customer cares for Chinese apps? Crazy I guess they get paid to include on the crap sort of like advertising. Hate it.

Anyway the Mirek V6 runs like a charm, very smooth and fast, and even battery use appears good. Only thing I dislike on the X98 at this moment is that the screen is too bright both in Android and in Windows. Have looked for some setting to just change the calibration of the screen brightness gauge both Android and Windows but not found sofar. Anyone have some tips? There are plenty tools that apply some screen filter but really that is not a good fix. It should be possible to tune down the LED background, which also lets you battery last longer.

Talking about that there is no auto brightness adjust it seems. Did anyone try to use the camera as a brightness adjust sensor?
[Teclast X98 Air 3G] mirek190:
Thank you

I can not to lower brightness less because screen stop working ....

---------- Post added at 04:47 PM ---------- Previous post was at 04:47 PM ----------

I updated 4.4 to v5 - have fun :)
[Teclast X98 Air 3G] EricCrapton:
Brightness

Too bad this can not be adjusted in a better way. My Samsung Tab2 10.1 can run down in brightness quite far so how do they do it?

Battery

Other comment I wanter to make was regarding battery use. On Windows 10 it used 35% in 2:45 hours run time with low brightness 5%, just Wifi enabled, also the 3G of course but no GPS or Bluetooth. Doing mails and some web surfing. This yields just over 8 hours run time. Will need to do some more testing with better data.

On Android with Mirek Lollipop V6 same conditions went pretty good today almost entire day say from 8:00AM through 6:00PM from 100% down to 55% which is fine and better than Windows. Then I tried part of a movie using VLC player and now I look agains and suddenly have only 14% left??? Really sharp drop in battery capacity suddenly! VLC player was off for sure and does not show up as a running task in Apps or System Panel Lite. Confused now... what causes this?

Charging is not as bad as some say based on measured values it should recharge form 0% to 100% in around 4 hours, which is not too bad. Using the supplied charger which is 2.5A. Not sure if a more powerful charger would speed up the charging process, did anyone try? Where is the bottleneck?
[Teclast X98 Air 3G] mirek190:
Why you are using vlc ? MxPlayer is way better and use gpu not like vlc software rendering .

Apart ft9m 5hat you have to remember battery indicator is not very accurate .
[Teclast X98 Air 3G] MaK11-12:
Just had this problem. Use the tutorial here to fix your issue. This will flash a really old BIOS though. To flash a newer BIOS, replace the "X98Air3GA.bin" and "X98Air3GW.bin" files with the BIOS 2.05b version.

On another note, I just flashed BIOS 2.05b on my Teclast X98. Unfortunately, attempting to install Windows 10 32bit failed, so I tried to install Windows 10 64bit instead. This caused a blue screen then bricked my tablet.

Really dumb how a supposedly 32-bit UEFI BIOS would boot a 64-bit installation. Rather furious that I have to unbrick my tablet yet again.
[Teclast X98 Air 3G] kostas-k:
I have installed Lollipop v6.0 but due to camera not working, I need to go back to 4.4 v5.0. I must do a clean install only or I can do with Dirty? Because with dirty one, it stuck on boot image with the marbles and do nothing for 2-3 minutes, when I force to switch it off

Do you remember if the camera worked in Windows 10 and if the screen rotation was ok? Because I have a C9J6 and I'm thinking of doing it
[Teclast X98 Air 3G] mirek190:
Always ( epecualy from 4.4 <--> 5?0 ) clean flash is recommend .
[Teclast X98 Air 3G] Rivuzu:
Right, so stupid newbie time. Hi guys.

Air III 64gb Dual Boot received. Had it since Saturday. Been working absolutely fine on both Win10 and Android5.0. Couldn't of been happier with it - until just now, when showing it off to a co-worker, when I tried to demonstrate booting it into Win10. Something's gone a bit wrong.

From what I can see, it's stuck in the fastboot launcher as it's not allowing me to select an OS to boot to at all, be it Android or Windows, and is constantly just restarting. I can access the fastboot launcher with the + and - key, but have no way of inputting anything onto it.

Someone fancy giving me the ELI5 version of how to restore this to how it was? (Or am I up a creek at the moment?)
[Teclast X98 Air 3G] dafunky:
Don't you have a faulty button? volume/power constantly ON?
[Teclast X98 Air 3G] Rivuzu:
Not as far as I can tell, no. Doesn't try to boot on it's own.

I'm guessing faulty eMMC which is now unable to get past the bios.
[Teclast X98 Air 3G] apedro:
Does anyone know where to find the bios for the Teclast X98 3G (HKC1) (not the air version, with processor Z3735D)?
[Teclast X98 Air 3G] BoORDeL:
I've got a problem with sdcard and fast OS switch.

If i fast swap beetwen android to windows, windows system can't handle sdcard.

i found a workaround that solve the problem by shuting down android, removing sdcard, wait for win 32 bit uefi bios load, and than reinsert sdcard.

i've got bios 2.02, mirek KK rom e win 8.1 pro.

anyone else experienced this issue?
[Teclast X98 Air 3G] dmandic:
This is funny, first Win 10 that i installed (Home with X98 drivers included) had working back camera, but not front one. Later when I reinstalled Win 10 Pro, and installed drivers separately, both cameras are not working...

Rotation worked on both versions, after installing patch provided on forum.

Nobody came with idea what is causing errors (two win boot loader) in dual boot menu when I recover Win 10 partition image made with Macrium Reflect? I suspect it is caused with MBR or something like that, but I don't have that deep understanding of filesystems...

Can I edit dual boot menu somehow to fix it?

On normal PCs I've been using Ghost and Acronis True Image for decades without any problems.
[Teclast X98 Air 3G] EricCrapton:
3G working partially????

Guys I am lost here.

I have a SIM from a local provider. Switch off WIFI. I test this in my old Galaxy Tab2 and have no problem to open web pages in Firefox Android. Enough MB available, 3G connection is there etc.

Same SIM in X98 with Mirek V6. I adjust all settings the same, APN etc. Switch off WIFI. No web page loading Firefox Android, my Whatsapp text and smileys however working almost instantaneously two ways. But high res pics both ways NOT working. Lo res pics I do see both directions up and download.

So almost like there is some filter cutting off anything larger than say 1024 bytes or so. WTF??? The notification icon shows 3G signal strenght OK, with an R and and an "!" mark. R probably for roaming which I happen to need with my provider. Also working in stock Android browser does noet change anything, it does not even open google.com but is like stuck at 25% error name not resolved.

Is there a bug somewhere in the ROM? Or is this some setting somewhere?

Also today battery went down from 60% to 20% in like 30 mins, straight line. Not even using it.
[Teclast X98 Air 3G] rudnik8:
I have this problem too, but my workaround is to just turn off android, and boot to windows via boot screen. It works for me
[Teclast X98 Air 3G] BoORDeL:
EDIT:

You are right mate, same behaviour for me.

it seems fast switch doesn't unmount properly sd device leaving it in a blocked state.

Anyway a clean shutdown solve the problem.

Thank you
[Teclast X98 Air 3G] BoORDeL:
i solved camera issue by downloading win 10 drivers from techtablets site.
[Teclast X98 Air 3G] EricCrapton:
Tried a lot of things such as dialing *#*#4636#*#* etc, calling my provider, putting the SIM in my old Galaxy Tab2, checking Android Status. APN is OK according provider and what I find on Internet. It is the same as on my Galaxy Tab2 on Kitkat 4.4.4. which has NO problem it works flawlessly so SIM or account are not locked.

Data bundle, SIM, provider, APN, general settings all are OK. Status tells me netowrk name, signal strenght -78 dBm, UMTS, In service, roaming (required by provider), network state = connected. Phone works, Whatsapp works and small amounts of data are transferred. Just loading a web page does NOT work so there is some data block.

IMEI is known.

I also read a lot about some bug in Lollipop 5.0? Could that be in this Mirek ROM? Anyway there is a connection to the provider network, there just is NO data. Anyone have a clue and can help?

UPDATE

I read that updating to Lollipop did cause quite some problems with 3G connectivity. One person flashed back to 4.4.4. and found 3G working, up to 5.0.1. and not working. He then flashed the "radio files" from 4.4.4. to 5.0.1. Very nice but how to do this?

Should cameras work in Android 5.0 with Mirek's v6 ROM? I have C8J7, BIOS 1.03 but both cameras seems don't work
[Teclast X98 Air 3G] apedro:
I finally managed to fix my bricked Teclast X98 3G (HKC1) with the programmer CH341A :o but now when I boot it I get the message "press esc in 5 seconds to skip startup.nsh, any other key to continue" and then 'Shell>' to enter commands :eek:. How could I have the bios options that I had before? I would like to flash just Android.

I think that the issue is that I do not have the correct bios. I do not find the bios file for the (HKC1) :crying:
[Teclast X98 Air 3G] SUMMERBREEZE:
all you need to flash this bios from your tablet (like you did before)

Hey,

I want to flash lite android rom and I need your help finding my VID and PID values. I can't access droidboot mode, when hold down volume - and press power button nothing happens. Tablet boots to desktop like always. My C8J7 tablet is running rooted android 4.4.4.

The VID and PID values i can see when tablet is connected to my pc: VID 8087 PID 0A5F

I don't know if it matters, but the VID and PID values in DnX mode are: VID 8087 PID 0A65.

Can i use them?

Thanks for your help.
[Teclast X98 Air 3G] Estiui:
Thanks, I'm still waiting to see some reviews of the Dual Boot model to decide. I've also the same doubt about the space splitted for both OS, let's see how it gets solved...!
[Teclast X98 Air 3G] SUMMERBREEZE:
this just came to my mind,

contact with your seller and tell him/her that when you ordered your tablet, it was advertised as windows 8.1 is possible to flash, but now you feel you fooled by them, you want to open dispute if you cant find a way to flash into windows :D also tell them that previous air 3g with ID code C6J6 can be flashed into windows.. Lets see what they will say :p

---------- Post added at 07:11 PM ---------- Previous post was at 07:10 PM ----------

so you also ordered air 3g with windows (possibly c8j7) :confused:
[Teclast X98 Air 3G] Estiui:
Could you post the complete review here? I can only access to the first part according to Google translation, since I'm not registered there.

Edit: [MENTION=3014815]SUMMERBREEZE[/MENTION], I've not ordered any yet. I'll probably order either Dual Boot version or Air II, depending on what I read or see on reviews. Because the original Windows version of Air II works well without screen lag issues, right?
[Teclast X98 Air 3G] G3n3R4L:
you need to rethink again .... we are using only 1.33 out 2.16 of the actual speed of the processor, we need the bios or we will be stuck with all that forever, and the fact that we can't change the bios configuration is terrible
[Teclast X98 Air 3G] SUMMERBREEZE:
haha i thought you ordered anyway :D

so all the questions you asked were just for pre-information then :laugh:

Those numbers are probably correct if 2 came from the computer and 2 from the tablet.

I tried to install Xposed framework last night and it bootloops the tablet with the lite rom.

Has anyone tried to install it on the official 4.4.4 rom?

It is easy to recover the bootloop.

Just restart the tablet and keep repeatedly clicking the Vol+ button until the tablet starts. You should hear 4-5 beeps just as the tablet finishes booting if it has worked.

It was working fine on the 4.4.2 rom.

I miss youtube ad block haha.
[Teclast X98 Air 3G] supercowz:
i had the same problem with xposed, i got a bootloop, what i did was VOLUME - and POWER

then i was able to boot android 4.4.4 in secure mode, then i done a factory reset.. in android setup menu ....

no more bootloop ...

another method to fix the bootloop ...

---------- Post added at 07:58 PM ---------- Previous post was at 07:54 PM ----------

I did receive this today....

Useless

U can OTG, u can charge, but not at same time....

crappy quality, mine have bad contact when you touch it u lost otg or charge ... dont buy it ...
[Teclast X98 Air 3G] HDtracer:
Ah that sucks, you lose all you settings :crying:

It all becomes very painful and time consuming with no custom recovery.

Xposed has included a bootloop recovery file now.

You just have to workout which button it is and click away as it boots and it automatically disables the Xposed framework.

Which ROM are you using?
[Teclast X98 Air 3G] Petepe10:
Waiting, waiting...

,,, for my x98 air 3g android.. I hope it will arrive before Xmas...

I try to keep up with the thread, thanks for all the contributions.

My goal is to have a rooted device without bloatware, either by deleting the apps myself after rooting or the lite rom.

(Perhaps after all the dust has settled down a dual boot. )

But it is sometimes confusing. So I guess there are now 3 HW versions, each with either android or windows factory installed, plus all cases where the OS was changed, Win>And, or And>Win, which makes 12 combinations (not considering the original air/air ii without 3G), that may or may not have some problems.

So I wonder, assuming I will get the latest HW version and 4.4.4 (factory or OTA or flashed rom), what are the remaining issues?

- Google app store: still present or needs to be fixed (fixes present, so no big deal)?

- mike issue (same - solvable)?

- Slow in responsiveness? Is this due to the teclast tUI?

- 3G: some problems with a few providers so it seems

- Lite rom based on 4..4.4: issues with Exposed framework

- Overheating message playing video/gaming causing screen brightness to lower

- Headphone/mike combo not working - distortions with 4-way plug?

Am I still missing something?

Thanks,

Pete
[Teclast X98 Air 3G] eltigroUK:
Are you sure about this? The turbo speed is 2.16GHz. Check under performance tab of task manager to find out peak performance.

My X98 air standard clock is 1.33GHz buy will peak at 1.86GHz when pushed.

If you are stick at 1.33 they mustn't have coded the bios properly to use turbo peak performance which I find unlikely.

Hi,

If you are staying with android the tablet is awesome.

Playstore needs to be fixed, no big problem.

It doesn't work as far as i can tell because of the Chinese government restrictions on google rather than any tablet problem.

Mic issue is a simple fix thanks to Frontier. (just lazy coding by Teclast)

Xposed is always a crap shoot as to whether it will work or not, sometimes it will sometimes not.

The tablet does get warm when playing fullscreen HD movies, but then the power drain to drive that screen is large too so not really a problem.

The headphone plug is the only problem I have, which is just a stupid problem for a tablet that can make phone calls but cannot support a headset :confused:

All in all it has been money well spent.

---------- Post added at 08:46 AM ---------- Previous post was at 08:41 AM ----------

To start the flash, tablet needs to be disconnected from the computer and in DNX mode then plugged into computer and flash will stat automatically.

Is this how you did it?
[Teclast X98 Air 3G] Mikha777:
It's because you don't have any OS installed it boot directly in the EFI shell. If you want to see the Firmware (bios) screen you have to press ESC key during the boot. :)
