Your model is the HG9M if it's dual boot and 64 GB.

---------- Post added at 09:18 AM ---------- Previous post was at 09:14 AM ----------

Some people get this behaviour due to overheating, overheating is frequent when the GPU is heavily used, so some people have underclocked it with good results, I personally have not done it and don't exactly know how to, but there's been talk of that in the past week or so. Also maybe on the first page there's info about that. Although this thread is meant for 3G variants, most of the fixes also work on the Air II

Hey seized,

I ordered a couple of them guitar picks from a US seller. Also ordered a manual ROM flasher, just in case.

I was thinking maybe I should order some thermal pads for when I open it up. Any idea what kind I should get ?

Here is the BIOS/EEPROM flasher I got. Someone here reported that it works.

Hi! I intend to buy this device (from GearBest, they say that they have got latest revision) but I would like to specify some things first:

* Can I install both Windows 10 and Remix OS 1.0 (I don't think we can put 1.5 on it... or can we?)?

* Can I connect my 1080p TV via HDMI to use as a mirror screen?

* How well does it play with Logitech Bluetooth keyboards? Or at least Bluetooth keyboards at all?

Thanks in advance for replies!
[Teclast X98 Air 3G] Bolemo:
So today I found the time to give that a try.

It did not work at first because the path is /dev/block/mmcblk0p3. Corrected that and the dd function worked well.

I got a bit scared because the original boot.img was 16,777,216 bytes, and the new one is only 10,604,544 bytes. Did the reboot and crossed my fingers… waited, it took some time… was hoping it was not soft bricked… and voilà: lock screen appeared and the touchscreen worked!!!

Thank you so much tecknight, that was really helpful and efficient.
[Teclast X98 Air 3G] siezed:
well theyre not like insanely different, i think arctic makes the best pad at 6 w/mk, the cheap ones are like 2-3 w/mk, but i mean copper is like 400 w/mk so if you can use copper that'd be the best, then paste to fill the microscopic gaps, and maybe a pad to get good contact to the back case. ideally youd take the stock pad off, clean the crap off with alcohol, add some thermal paste then a copper heatsink on top of each chip then more paste to fill the microscopic gaps in between the back cover and copper, but that would require a precise thickness of copper to get to the back case. I chose to leave the pad on just for fear of shorting anything out, but im guessing thats unlikely. anyways best is the arctic at 6 w/mk, so id just find a cheap pad close to that, or even of not its such a low thermal conductivity im not sure it would make much of a difference.

edit: according to tomshardware herehttp://www.tomshardware.com/news/arctic-thermal-pad,29137.html the arctic does perform measurably better than the other ones, so id go for the best w/mk you can find for cheap, arctics a bit expensive especially if you want to stack em.

I'm just wondering. What are the benefits of upgrading the BIOS? I'm running the stock BIOS currently on my DualBoot 64GB Teclast X98 air II and I've flashed Mireks v.3 ROM successfully on the Android partition and in the future I am planning on installing Windows 10 on the Windows partition, do I need to do something to the BIOS first?
[Teclast X98 Air 3G] siezed:
i have an hg9m dual boot 64g air ii and updated the bios to 2.02 and the two major advantages are no more battery drain while sleeping in windows and you can use switch os shortcuts in both windows and android, no more shutting the tablet off to switch os, push s button and switch works like a charm. Also some things require the new bios to work, so theres more to it than just those things. If i'm reading your second question right you are probably referring to saving your windows key, in which case all i did was use a windows key extractor so i could view the actual windows key and saved that, you can inject the key into the bios as a new bios will erase the key but its only gonna matter if you try and reinstall 8.1. Just copy your windows key with an extracting program just in case, i just took a pic with my phone so ill have it.
[Teclast X98 Air 3G] tecknight:
That's great !! I am so happy it worked. Thanks for the update on the partition path.

FYI, the reason the original boot.img was showing as larger is due to the fact that we copied the entire boot partition.

FYI, I am working on a modified boot.img for this tablet that will support all models of touchscreen hardware. I will let you know when I am done with it
[Teclast X98 Air 3G] guvno:
Thanks for that, good info. So I guess updating the BIOS could be worth while... Good to know that the key dissappears when flashing the BIOS so I will need to save it.

I assume you enter the key during re-installation of windows right?
[Teclast X98 Air 3G] tecknight:
guvno,

The key doesn't disappear when you flash the BIOS, it's still in the windows registry and your windows will remain activated.

However, if something ever happened to your windows installation and you hadn't previously recorded your key, you would not be able to activate windows. The reason is that the Windows installer will retrieve your key from the BIOS image automagically IF you still had your original BIOS. Yes, you are correct, once you obtain your key, you would physically enter it during re-installation of windows.
[Teclast X98 Air 3G] guvno:
I see. Thanks for clarifying! So basically after flashing the new BIOS you loose the functionality of automatically retriving your windows key unless you re-enter it into the new BIOS
[Teclast X98 Air 3G] tecknight:
correct.

Hi.

On bios 1..07, I have modified in windows registry power csenabled key (to enable hibernate, like it was mentioned in post #1). After upgrade to bios 2.02, I can't find sleep option in "advanced power settings - power button action". In fact, I cant put the tablet in sleep at all. Any solution?

[Teclast X98 Air 3G] siezed:
yea as tecknight said this is spot on, also as for windows 10 you will get a new unique key so if you upgrade the 8.1 key, as far as i know, will be worthless in reinstalling windows 10, youll need your new key so the bios saving the key isnt very important to me.

---------- Post added at 11:07 PM ---------- Previous post was at 11:00 PM ----------

Your issue might be different than what most of us are experiencing, for us we get the hibernation in windows and in android we get the "dimmed screen due to thermal event" message. It might be worth booting into windows, running a game or stress test/gpu burn in test and seeing if it auto hibernates, if it does check your event viewer to confirm a thermal event message. If not you may have another issue and id start with reinstalling android.

Hi,

I think I flashed the new bios 2.02 but I don't see anything new like changing to android or windows without rebooting. How can I confirm I am with the 2.02 bios? I don't have a usb keyboard.
[Teclast X98 Air 3G] siezed:
You can get into the bios through windows by swiping in on right, settings, change PC settings, update and recovery, recovery, then under advanced startup click restart now. Then when it restarts click the advanced options then change uefi firmware. You should see teclast v 2.02 somewhere. alternatively you could download the windows to android file on the first page and see if it works correctly.

Edit: In other words the bios doesn't add any features, it just allows them to work, you gotta manually add the boot to windows and boot to android apps on the first page.
[Teclast X98 Air 3G] joshua_89:
I don't find these apps you mention on the first page, sorry for the trouble.

[Teclast X98 Air 3G] astromark:
Mine came from Banggood and while it was in transit (the same day DHL took posession of it, which was 7 days after the order was placed) I had a text from DHL, wanting payment via their UK website for £15.00 for customs and VAT. The tablet was still in Hong Kong at this point. I paid it immediately and it arrived in the UK two days later and was delivered the same day. I presume they'd have held it if I didn't pay.

---------- Post added at 03:50 PM ---------- Previous post was at 03:47 PM ----------

I've done that as an in-place upgrade from Win 8.1. I then did a fresh install. I have now lost the auto-rotation of the screen and can't get it to work, tried everything including registry edits and additions and different drivers. Not too bothered anyway as it'll get zapped in a month or so with the RTM version.

To be honest it seemed to run more smoothly with the upgrade from 8.1, not sure why, presumably a driver somewhere is different.

---------- Post added at 03:55 PM ---------- Previous post was at 03:50 PM ----------

Actually can someone in Windows (10 if you have it) look at Disk Management and see how many partitions Windows can see please? There are LOTS of them on mine, mostly small 16MB ones. I am guessing some are Android, some Windows, some boot and some for the dual-boot BIOS. I was thinking maybe having tried three Windows installations, Windows had created lots but I now think it's meant to be like that. (I was going to have a tidy up but stopped myself....)

Teclast X98 Air 3G 64GB dual-boot default partition map

Here they are. 19 partitions total.

Check the attached PDF.

FYI: Do NOT mess with the order of the partitions or the existence of any of them or you will learn a very costly lesson. You can change the size of some of them within certain limits, but that will also wipe the content of all partitions, so you will have to reinstall both OSes.

I have ordered a Teclast x98 Air3g, yet to arrive but expected shortly. This thread seems to be a treasure for the device but with with almost 1000 pages in this its too difficult for a new entrant to make head or tail of the thread. I have read the OP but I find a lot of fruitful and essential advices of various nature inside the thread posts. So its really going to be difficult for me.

Why dont we request a separate forum for the device or it has already been requested and rejeccted.!! Further a split of this mega thread into sections would have been great but I think that would not be possible because of the sheer volume of posts.

Anyway thanks to all contributors. Hoping to join soon actively.
[Teclast X98 Air 3G] astromark:
Thanks Tecknight. I'm glad I held back on playing with them!

This may have been asked earlier but I wonder if that 4.8GB Windows recovery can be removed if a recovery image is made to USB or SD card, or even if Win 10 creates its own WIMboot image. It's a fair chunk to get back.

Edit: some searching in this megathread suggests others have removed it, but I'll leave it be for now :)
[Teclast X98 Air 3G] tecknight:
I would probably resize the partition to 0 blocks and give it's space to partition 18 (Windows user data)
[Teclast X98 Air 3G] joelxda:
Ok, so I managed just half a lap on Asphalt 8 in Windows and the tablet froze completely. I checked event viewer but didn't see any thermal event messages, just one about the system rebooting without shutting down properly. Also, I just wanted to mention that I too get the "dimmed screen due to thermal event" message in Android.
[Teclast X98 Air 3G] astromark:
Looking at the PDF you posted, I see my Windows partitions are slightly different. I'm not sure if this what Win 10 has done but:

100MB - EFI system

32.9GB - System/user

450MB - Recovery

4.69GB - Recovery

So I've got no 128MB MS partition but do have a 450MB smaller recovery. I'll see if I can see what's in it in a bit.

Meanwhile I have come up against a problem - I can't force Windows at boot to enter recovery. Trying to ask for it from within Win 10 results in a reboot but then a standard boot, not recovery. And I can't use F8/F10 etc on boot (with USB keyboard) to enter a recovery mode. I'm assuming the way this tablet boots (the dual-boot thing) gets in the way of what Windows normally expects.

I'm documenting this so others can learn.

try updating your graphics driver (here) if you have not done yet, it made my tablet a bit more stable, the only time mine freezes now without anything in the logs is while charging, it got really hot as well so it might have overheated.

I didn't have to change those settings for the apps to work, however I did have them both installed before updating the bios which shouldn't matter but just thought I'd throw it out there. Don't change those settings unless you know exactly what they do as I messed with em on a cube dual os tablet and lost windows all together, like the dual boot screen would pop up but windows was gone and no icon to tap ;)

New benchmark on Android?

HI again all,

I wanted to ask if someone can supply a new benchmark on the air 3g 64 gb version?

1) Will there be improvements in the benchmark if I falsh to a different ROM (Mirek?)?

2) Is the processor 1.3 Ghz or 2.13 Ghz? I'm a bit confused?

Thanks.
[Teclast X98 Air 3G] astromark:
Yes, I assume that's the Boot Override option in the BIOS under Save & Exit. This doesn't do anything; Windows boots as normal. That's trying to do it with either the Windows Boot Manager or whatever the USB drive option is named.

BTW this trick might help someone: the BIOS does have an on-screen keyboard, at the AMI logo touch the bottom of the screen. The ESC key (near top left, it's a tiny keyboard) takes you into the BIOS. So you don't always need a keyboard attached to do BIOS-related activities. You need to be quick, but once you're in you can change the Prompt Timeout in the BIOS so it'll wait longer before booting - I've set mine to 10 seconds.

EDIT: Curious, having just posted the above and now trying it again, selecting the USB device on the Boot Override option for the USB drive it's now booting to recovery. I don't know why it wasn't before but I'm doing nothing different. Still doesn't help, though, because (a) it's all in Chinese, but I have figured out what option is what, but mainly because (b) I can't get Windows recovery to want to do its stuff anyway; it won't recognise the recovery image from USB. I get "Windows cannot find a system image on this computer".

(For anyone else struggling I suppose there's always the twice-forced reboot option: holding down power til it powers down. IIRC after doing this twice it forces recovery.)
[Teclast X98 Air 3G] siezed:
I have thought about this too, and also struggled with navigating these pages. I don't think it's really feasible to split the entire thread up as that would take forever and likely end up as confusing as it is now. One idea I had was to just make a new sub forum when you have researched and found a fix, for instance I was going to make an "overheating troubleshooting steps" new thread and list all the things related to overheating and such. Someone could do the same with flashing a rom, list every model and clearly lay out the steps and link the posts that are needed. As right now a lot of "tutorials" are sort of universal and while the info is there, it's very confusing to someone whose never used these methods before. In the meantime, even though it upsets some people, don't be afraid at all to ask about where something is, use common keywords and stuff so future searches might lead someone else to what you're looking for too.

Your BIOS settings are fine. They match my settings exactly.

I think it has everything to do with the Android version you are running.

You are both running a stock Android ROM. The ROM seized and I are running (Mirek's Lollipop v3) had the Android OS switcher baked in.

In Windows it just freezes, in Android it freezes and then a couple of seconds later it reboots by itself. I'll give your suggestions a go, and if they don't help I'll probably just install one of mirek190's roms.

Little problems or question to ask!?

What a long full of information post.

I just want to thank everyone in advance.

I started get my hands on my C5J6 64Gb X98 today after reading most of the post.

I did understand that Windows Key was safe even if updating Bios to 2.02 so I didnt extract it........

Updated was ok, Dual OS works, BUT Windows 8.1 keeps telling me is NO ACTIVATED. Try to extract the Key with ProduKey program and seems like the key got erased from BIOS. Manually activation doesnt work.

Can I inject the key back to BIOS? Do I have to?

Also wasnt able to get GetWindows10 app to ask for a free copy. Script download from page 194 (if I remember) also didnt work.

Is there another way to updated to Windows 10? or reactivate 8.1?

Also in Windows SIM card gets signal but NO INTERNET. No APN admited.

Anyone can give me some advice?? Thanks
