Bricked Tablet?

Hi Mirek,

I have C8J7 with Stock ROM.

I've tried your BIOS update package," X98 Air 3G Flasher bios 2.02 - works on 100 % on C5J6, C6J6, C8J7" from Android (V4.4.4). Flashing succesfully finished & warned me to " Shot down" tablet.

Now, it's BRICKED. Can NOT boot anymore!!

Any change to recover it or Only chance is to use Eprom Flasher?:confused:

Thanks,

Macikus
[Teclast X98 Air 3G] artur.tfb:
Don't worry, use Eprom Flasher. This is a safe and good way for unbricking after unsuccessful BIOS upgrade.

Can you get into Dnx mode? If so, flash system, if not you may need bios programmer.
[Teclast X98 Air 3G] simc1978:
Good buy?

I'm tempted to get one of these, I think primarily for windows use? Does anyone know how the battery life varies between running windows and android? Is there any difference between the 2 variants as sold or can I save some money by buying the android version and flashing windows when I get it? Does the 48Hz issue just affect gaming, Given the problems do you think it's a good buy.
[Teclast X98 Air 3G] G3n3R4L:
for me i bought the android version and flashed windows myself, but as you can read we have some problems, in the meantime the air 3g is out with fixed drivers such as the camera "which we already fixed" and the 60hz .... so as personal i recommend you to pay more 20 euros and get yourself a clean tablet with stable windows version better than wasting your time with us trying to fix, the battery is going for 7-8 hours on windows, i didn't use android to tell you how much time will be on android ....
[Teclast X98 Air 3G] Hendrickson:
It's so typical of Teclast, they wont post a 48hz or camera fix. Yet they WILL sell you a new Air 3G with Windows installed with 60hz and a camera fix.

It's either because of two things, they can't fix the 48hz issue has it's a hardware limit in the older batches of the Air 3G. Looking at my Air II on 60hz and my Air 3G @ 48hz there are hardware differences in the monitor inf's as described in posts a few pages back.

OR: They don't care and only give push out fixes in new units they want to sell.

Personally, I think it's both! And there is a plus side to 48hz, it does save battery. On my Dell Venue 11, Intel power saving feature would switch the screen between 48hz and 60hz. The real issue for me is the camera (I use skype) and the fix when applied messed up my top half of my touch screen :( (Boo hoo for me, works for others)
[Teclast X98 Air 3G] majkel_94:
I'm curious whether the Win version can be convert into Android or they really make new batch with different hardware :confused:
[Teclast X98 Air 3G] G3n3R4L:
i don't understand ! but if you ask about the hardware specs and if it's compatible with the two systems, so it's yes you can weather flash the windows or android on the device, but ofcourse some work need to be done such as the bios, and flashing the system after
[Teclast X98 Air 3G] SUMMERBREEZE:
I am happy for you that the battery went back to normal, cos it seemed a worse problem than 48hz and camera issue IMO.

And yes, you are right about your doubts for Teclast, they just want to sell the new units ans they dont care about us. I really dont believe that they dont have such techicians or engineers that are not warned about these issues, im so far sure they know about these all.. but no improvement at all.. so pitty..

I am not a gamer at all, i may be watch only films, youtube etc. so 48hz is not a monster problem to me, but i would love to use the camera without problem while im on Skype or Facebook etc. I will try the fix for camera at a few pages back and see.
[Teclast X98 Air 3G] BoORDeL:
I really don't know couse ANDROID BIOS is 64 bit UEFI while windows one 32bit.

I don't know if you can flash android bios c6j6 on c6j7, but if this would work properly, may be we could do the same with c6j7 bios.

---------- Post added at 17:11 ---------- Previous post was at 17:07 ----------

I am lucky with my C6J6.

The only issue i am experiencing is 48 Hz video refresh.

Anyway as stated from other users before, i'm not a gamer so i am really not experiencing problems.

Please notice that our C6J6 on android or UBUNTU (http://bbs.teclast.com/thread-255275-1-1.html) or other OS installed over 64 BIT UEFI BIOS have 60Hz video refresh.

So for me it's easy to say that there was a bad implementation in the first type of 32bit uefi BIOS (c6j6)
[Teclast X98 Air 3G] heikkiap:
I can have 64 Hz refresh rate, indicated in Monitor tab in Advanced display settings.

How is that possible?

When you don't yet instal Intel HD graphics or uninstal it, you can see 64Hz instead of 48 Hz. Is that a real refresh rate, I don't know. If it is real, then it is not a bios problem, but a driver problem.

[Teclast X98 Air 3G] SUMMERBREEZE:
if it is a real refresh rate without driver but after driver installation, it locks itself to 48hz, then it seems a driver issue but in the other hands, we think its a bios or even its a bad hardware issue etc. really interesting.. hope we will not die before fixing this issues guys :p
[Teclast X98 Air 3G] BoORDeL:
As i said before why the same driver works properly on C6J7.

We all know that C6J7 Windows ISO is hte same crafted for the C6J6
[Teclast X98 Air 3G] SUMMERBREEZE:
thats why i added it could be a bios issue. I understand you, the same driver locks the refresh rate to 48hz on C6J6 but doesnt lock on C6J7.. working properly as 60hz :silly: and windows iso is exactly same for the two tablets
[Teclast X98 Air 3G] majkel_94:
Bull****.

I've just downloaded the C6J7 version and the MD5 is different!

Hi together,

now I have my tablet too. After rooting my tablet I made a mistake. I erase the Teclast Autoupdater app.

Can someone send me or show me where I can find this app ?

My second question. How I can start a LiveUSB Stick with Ubuntu 14.04 ?

I have a USB Hub and keyboard and mouse. But when I like to start with the Stick the Tablet runs only in the normal OS.

Hope we have a chance to become a System like a smal computer with booting three OS liek Android, Ubuntu and Win8.1 or win10.

Thanks...

[Teclast X98 Air 3G] Dudeonyx:
Question

If i read that Ubuntu post on the teclast forum right, it seems that the method used to install Ubuntu allows true dual booting but only win/win or win/Ubuntu and not win/android ?

Edit: it seems the touchscreen doesn't work due to missing drivers?
[Teclast X98 Air 3G] BoORDeL:
As stated some posts ago (RTFP),

Windows 8.1 can be installed only on 32bit UEFI BIOS.

Android and Linux on 64bit UEFI BIOS (and windows xp 64).

All depends on vendor implementation.

UEFI BIOS is shipped only on 64bit distributions of linux while intel has product his drivers only for 32bit uefi bios.
[Teclast X98 Air 3G] G3n3R4L:
but it seems to be true, what's wrote on the teclast forum is that you can dual boot win/ubuntu ... you speak right, but they mentioned something else on teclast forum, did you try installing it ? and what was the result ?
[Teclast X98 Air 3G] soudara:
i'm sure the refresh rate it' 48hz because in 3d game if you use vsync caused lag in game because screen not syncronised with the game spec refresh rate 60hz for super street fighter 4 i test with low resolution 640x480 is the same problem ,48hz on c6j6 it's real problem

my question is c6j6 and c6j7 had same hardware or not ? if the same hardward we just need to flash c6j7 bios on our c6j6

it's possible for c6j7 user dump and send bios here

thank you

Finally, in order to increase the System available space for Android I lost all partitions and I have to re-install everything from scratch. I don't like remix OS with chinese tools/characters, so I'll wait for Mirek's v2. But my question now is for Windows.... What is the last? I don't see any "update" on third post, does that mean that Win10 still not a good option? What about the wimboot method to save a lot of space in Windows partition? Is it worth? Is it easy to install that way?

Thanks in advance.

If you want a way to get more storage in Windows you can try Simon King's Zip Magic 12 Doublespace.

- 1 GB system

- fully rooted

- removed all Chinese programs -

now really everything

- busy box

- init.t

- zip alignment

- deodexed

- updated. Google services, Google play, YouTube

- adblock ( need root )

- resolution changer ( need root )

- ViPER4Android FX - need root now sound is really good and noisy

- Apex launcher

- Total Commander - for file browsing

- tone of optimizations for :

internet speed tweaks

GSM/3g tweaks

WiFi tweaks

vm management tweaks

kernel tweaks

tweaks in kernel ramdisk

battery tweaks

optimisations, tweaks for ETX4 partitions

governor and I/O tweaks

tweaks for memory ( RAM ) and lowmemorykiller - heavy multitasking works nice !

and more I don't remember

IMPORTANT​

I recommend wipe data because I changed a lots of things in virtual machine and no all optilimaziations will be work propely until you make data format .

I created xml file called flash-system_only_and_format_data.xml for it !

In that case maybe try to improve your radiator that taking heat from your cpu - maybe iit s not installed properly. Mine after even 1 hour of intensive playing not shows me information about temperature

Or you can reduce cpu speed if you want - find some cpu control in play store .

About camera not working - I didn't chance anything about the camera - for me wasn't work at all on 5.0 so far .

We can wait until teclast release 5.0 for older devices or trying repair ourselves by adding driver to kernel from 4.4 ...maybe will be work.
