How to DUMP bios in windows

[MENTION=320897]People[/MENTION] having stock

C6J7

tablet with orginal bios

Can you please dump your bios and share it with us?

Here there is a zip file.

Unzip the directory and go inside.

What you should simply do is run as Administrator the file

flash.bat

.

At the end it will create a file named bios.bin in the same directory. This is the file you should share with us.

Don't worry! This is a only read operation, nothing happens in your device! It takes some seconds.

Thanks.

c9j8 bios

*this reply are editted, because i thought i write in PM

i have c9j8, now with c6j7 bios flashed (48hz refresh, windows only). the benefits is battery life is great (10+ hours home usage), but the cons is i've lost 3g data hardware, but gps still there. since i'm not using 3g data, i think i will keep the bios.

anyone have stock c9j8 bios? or share the dump bios, since i forgot to bios backup. I just want to keep it in-case i want to get the 3g or dual-booting back.

Hi guys,

Been trying to take the 600+ pages in and im feeling a bit over-whelmed.

Im hoping to buy a x98 air 3g 64gb dual os in the next few days

Could someone tell me what is the latest version? is it C8J6 or C9J6, Is it just software updates between these versions?

And where would the best current place to get it be?

thanks heaps

Joel

That's really strange! All people here lost GPS, while you lost 3G! :)

Are you sure your GPS is working? I'm quite sure not... For 3G hardware, try to reinstall drivers, maybe it came back.

Anyway i remember you that battery drain is here in this bios too...

We need original 60Hz C6J7 bios... to have all fully working!
[Teclast X98 Air 3G] abanglek:
yup, maybe different hardware on c9j8. gnss switch is there, but i never try it, try download here maps but its pending, will update later. no 3g data option. on device manager, only have 3 sd host adapter instead of 4.

as screen refresh rate, my first criteria for the c6j7 bios is because of the 48hz. i belive 48hz instead 60hz make different to battery life. in my dell v130, theres option for 40hz or 60hz, & i pick 40hz for battery life & some performance. & the thing is, in my bare eyes, i didnt find any different, for normal task or watching movies, 48hz (or even 40hz) more than enough to avoid stutter or flicker. even default video camera setting is 30fps.

i want to try to find out how to force (lower) screen refresh rate on stock bios.

so anybody can share c9j8 bios dump?
[Teclast X98 Air 3G] vpx:
If you cannot see your USB flash with exact name, e.g Kingston DT 101 in Bios, and one time boot override, your USB is not recognized correctly. You need compatible USB OTG hub, no Teclast connected USB OTG cable to normal USB hub. If you do not have right USB OTG, you are not able go to Bios with keyboard and USB stick in the same time. I am not sure, but I needed to put USB stick into hub *before* powering tablet ON, otherwise it was not visible in Bios too.
[Teclast X98 Air 3G] abanglek:
i though here maps have turn by turn navi, but it's not. i don't know how to test the gps (& maybe even after few years i'll never use it).

i've try to replace all the drivers, because i don't know which is the 3g driver, unless the folder written the hardware or contents obvious like intel display driver. & the mobile broadband switch are back, maybe it's my fault skipping the driver & device manager not showing any error. but i never try it since i dont have adapter to my nano sim..

em, maybe c9j8 & c6j7 shared the same hardware?

anyway, thank you..

Just make sure it is indeed the Dual Boot version...and don't forget to thank whoever helped you.

This was already discussed here in the thread.

It's suggested by many tests that the maximum frequency it can take before it freezes is 500MHz

Just confirming

Hi guys,

So just to confirm so as to make sure I understand correctly.... Regardless what x98 air 3g 64gb dual-boot I get, it will not matter as the hardware is identical and in the worst case I can just do a OTA update to get the latest ROM? So that would then mean that C9J6 just stands for the rom and in this case its the latest available release?

Also I read somewhere that initially the hardware you got was a bit of a lottery... Is this still the case with the x98 air 3g 64gb dual-boot?

thanks

Ok, I understand but I was trying to explain that I have left the original max frequency of the gpu to 646mhz and changed only the minimum frequency to 313mhz.

This way I have the same performance in games and got rid of the 3d freezes.
[Teclast X98 Air 3G] abanglek:
Yes, i'm talking about my x98 3g. Nope, i'm not 50, i'm 35. I have experience varieties of oses from dos, linux to mac, varieties of game consoles from nes, handheld whatever. Phone from windows mobile 6 to android to iPhone to windows phone 8. Mostly jailbroke after minute out of the box. Yes, later i was a theif, but now i'm paying whatever i feel worth.

I need triple times to get work done in my Windows x98, without esp touchpad, selecting is a ass pain job. Of course no problems for casual usage.

As for android, it forcing me to use both hand, even for casual youtubing, which is not happened to 7" tablet. Yes, I've tried 8" android & I hate it, still forcing me to use 2 hands. Still I feel, 7" 16:10 is golden ratio for android. Seen many times, big android are abandoned, just keeping dust. Not happens to iPad, even with thousands crack, people still use it.

Ios know how to optimize iPad, you can type as fast as you can. But for some reasons I'm no longer supporting ios, they're lost from their own path.

In the end, it's your money, do whatever you want, I'm talking not because of hate, but only opinions. I sell 1 of my lens to get this tablet, not a regret, since I'm not use the lens too much, so it's just a fair replacement, not really using it. & still I want real laptop, light, thin, but big on screen size. I just want my bloody job done.
[Teclast X98 Air 3G] antony84:
Mine is C9J8 tablet too.

I also flashed 48Hz single bios, but i lost GPS (it was there, but simply didn't work). 3g modem was there.

I didn't test battery life with 48Hz bios, but with Air II bios i can reach 5 hours with screen always on.

How do you reach 10+ hours? The screen is alway on? What activities you run in this time?

It seems too much 10+ hours consecutively!

Can i have some inputs from other users? How much is your battery life?

Hi [MENTION=2470600]supercowz[/MENTION], thanks for sharing with us.

I would ask you about the differences in battery life with and without it.

I'm interesting more in windows usage, how much was before and how much now your battery life? Wich bios are you using?

Thanks

Is your tablet completely standard? If not updates will fail for all sorts of reasons.

Even just being rooted will most likely cause updates to fail.

Exactly which drivers I have to update to get the BT and WLAN working at the same time on C6J6? I've tried every BT driver I've found but provided driver has always been incompatible. My WLAN disconnects when I connect my BT mouse.
[Teclast X98 Air 3G] Hendrickson:
The drivers are the same across all the models, it's the same hardware from realtek.

It's disabled on this this bios the GPS. Having tried all the bios, I think this one is the best for Winidows only users as you get super screen brightness (Quite a few nits over the dual bios), 48hz doesn't seem flicker on 3 tablets I've had and the best battery life of all the bio versions.

Cool, we were talking about the same thing!

I can confirm that is working magic on my Win 8.1 installation!

I tried free version (with lowest space saving features!) and it gained almost 9 GB on my C disk.

I used to have around 800 MB free, and now I have over 9 GB, and I can see no disadvantages regarding speed of system or others...

connected standby issues...

Hi, I did your fix and got sleepstudy working, however, my battery drain is still high in connected standby 3% per hour or 800-900mW consumption. I dont think battery consumption changed before and after the fix.

Microsoft advise that :

"The traditional ACPI Sleep (S3) state consumes 500 milliwatts or more of average power consumption to maintain memory in self-refresh and enable the platform to wake on user input. This gives the typical mobile system with a 45-watt-hour battery just under 100 hours of sleep time on a full charge. However, connected standby systems use low-power memory and power-optimized embedded controllers to consume less than 150 milliwatts in most configurations. As a result, the typical connected standby platform can stay in sleep for 300 hours on a full battery charge. This is three times as long as in the traditional ACPI Sleep state."

Do you have any idea how I can get closer to 150mW on my Air II?

Today I updated WiFi and Bluetooth UART driver with newer version 3007.7.915.2014_Α01 by Dell. Tested the battery draining after that and after one hour on sleep mode, there was no battery drain at all. Before the driver updates, the battery drain was at 16% in one and a half hour. The command powercfg /sleepstudy reports that there is No Battery Draining at all after the update. Hope that's not luck only :)

The test was done while having 7% of battery charge, I'll test tomorrow also with full battery to ensure for the result!

Two problems... no solution! Help!

I'm really beginning hating this tablet!

I got it from 10 days, and i cannot get solved two great problems.

My configuration is Air II bios (the only one without battery drain) and fresh windows 8.1 with bing installation.

1.

Wifi huge slow performance

My tablet starts from reboot working good, good and correct wifi performance, but after some time, i have huge slow performance! My dowload rate slow down to 1Mbps! I get this on lan streaming and wan download too, while other my devices work perfectly. A reboot seems to fix it.

I tried update wifi drivers, using original wifi driver, dell wifi drivers (even new drivers reported by [MENTION=515543]kostas-k[/MENTION]), and trying teclast wifi fix too. No one solve my problem!

And more, i'm not using any BT device, the bluethoot is turned off by airplane mode. If it's important, I have original teclast BT driver, because dell BT drivers are not compatible while install.

So, please, can you tell which configuration is working for you? Which bios? Which drivers?

2.

Very bad battery life

With Air II single bios i get 5 hours simply leaving tablet on, without any running task. How is it possible? I read here you got 10+ hours, it seems impossible for me! Maybe my battery is faulty?
[MENTION=912680]Kar-El[/MENTION] and [MENTION=960178]abanglek[/MENTION] which configuration are you using? Bios?

Didn't change anything, but didn't notice that my battery was at 7% charge, a usual "bug" in the tablet with stuck battery percentage in 7%, so maybe the stuck indicator made the No battery drain. I'll check tomorrow with full battery

I installed the newest Intel graphics drivers also and had no problem with touch or rotation. But I never had this kind of problems that's why I tried that update also!

P.S. After some usage the battery indicator reached 6%, I'll check with full charge to make sure
[Teclast X98 Air 3G] kiru:
Your tablet is only reading the stats of one battery (this tablet has 2). Please read the OP on how to re calibrate to get the proper stats. You need do some setting, then fully drain the tablet and then your battey stats will be more accurate.
