I see, Have you ever run into some dump games that need to check whether a proper USB mouse is attached or not ? Wonder if there are any free dummy USB mouse driver floating around :( .

Your X80HD mod looks awesome btw, too bad i've never done much on modding the tablet. Do you know how hard is this relatively compared to changing stock PC i7-950's heatsink to cooler master hyper 212 evo ? that's the only heatsink mod I've ever done. Would be nice if I could successfully mod it as my x80HD runs around 86c playing graphic games :(
[Windows 8 General] sbasil:
Sure. Upload it somewhere and I'll check it out asap. :)
[Windows 8 General] mr_kaboom:
Maybe mediafire or Google Drive, One Drive. Thanks you.
[Windows 8 General] paradoxez:
Could you please do me a great favor and link me to the one you purchased on AliExpress ? I'm a bit confused about their spec (i.e. w/m-K, etc.). Also, do you still require metal shield plate for the tablet ?
[Windows 8 General] MacArthur67:
No, I actually don't use the tab for anything. I gave it to my 7 year old son to learn and play on. He's old enough to mess it up totally sometimes, but not old enough to fix it afterwards and that's when I have to take it for a while. Anything that can go wrong usually goes wrong so it's good training for me too! :D

86°C is definitely to high. It starts to throttle at around 75°C I think, but I haven't tried to study the thermal policy or done any deeper research in the matter. I just repeated the heatsink mod I did in my X98 Air. It helped a lot in the X98 and it's very easy to do so why not apply it on the X80HD also.

The mod is easy to do. The whole back cover can be quite easily removed using plastic prying tools (google it). Remove the SD card (important) and start in the opposite side to the side with the connectors (USB, HDMI, headpones). Then gently remove the tape around the metal shield plate/cap and pry it away with plastic tools. Be careful not to drop it on something that might cause a short circuit. Remove the original thermal plaster from the CPU and PMIC. Clean them with a cotton bud dipped in some alcohol. Put on thermal transfer tape or just heatsink plaster to make the shims stay there, put on the copper shims, put some heatsink plaster on top, put on the metal shield. Be careful to put the metal shield right in the small metal clips on the circuit bord. Easy, but be aware of static electricity, use plastic tools and try not to touch the components on the circuit board. On your own risk of course. :)

You don't have to worry about the thermal conductivity and such things as long as you use copper shims. You are limited by physical dimensions and not the design of the heat sinks so much.

I wouldn't remove it completely, possibly modify it if I wanted to spend my time on that. You need the electromagnetic shield (Faraday cage) around the high frequency electronics. Not because the microwaves could do any harm to you but possibly to other electronics on the board. Also the high freq. electronics is sensitive to incoming waves/radiation. If you want to spend a lot of time on this you could perhaps make exact openings for the copper shims in the plate and use much thicker shims, but don't remove it completely.
[Windows 8 General] MacArthur67:
I really don't know how to delete my Win 10 reg key that is stored somewhere in the BIOS. I can easily open the .bin file in a BIOS editor or hex editor, but I don't know where to look. Due to work abroad I also don't have time to search information about that right now. Do you know of any easy method to remove the fingerprint of my device in the BIOS backup (.bin file)?
[Windows 8 General] paradoxez:
Got it, thanks for a detailed guide. So I take it that I should go with thermal adhesive if I'm feeling confident to not screw up putting on the permanent adhesive. Otherwise, go for a less thermally conductive , yet more re-fixable thermal tape, right?

Don't worry , if I ended up failing then it's just fate telling me to get the new cherry trails series .

Thanks a lot :). I'm excited to see how it goes
[Windows 8 General] sbasil:
I found my product key this way with XVI32 hex editor:

Search --> Find --> Text string (where I copy pasted my product key) ==> Text -> Hex ==> OK

It was easy to replace with some other key by using the replace function.

Search --> Replace --> Text string (paste your product key) ==> Text --> Hex

THEN ==>

Replace with --> Text string (your new product key) ==> Text --> Hex

==> Replace ALL

Don't know if it actually works, but at least the product key gets changed. :)

The Hex address for the product key started from 71E016
[Windows 8 General] MacArthur67:
Actually it's easier to remove the shims if they are on heatsink plaster than on the 3M transfer tape. That tape is extremely sticky, whilst the heatsink plaster becomes more like a dense foam. Also, if you use the plaster you have a few minutes to adjust the shims before it really hardens. If you drop your tab I guess that the shims would never come loose on the tape, but maybe on the plaster, depending on how much you use. I used tape on top of the chips, between chips and shims, and plaster on top of the shims, between shims and the shield plate. I used a cotton bud to spread the plaster on the shims before putting on the metal plate. However you do it it will become an improvement over the original careless design.
[Windows 8 General] oile:
And did you flash the modded bios afterwards?
[Windows 8 General] sbasil:
Read my post again ("Don't know if it actually works, but at least the product key gets changed. ") (=Nope, I had no reason to do so)
[Windows 8 General] MacArthur67:
Thanks, I followed your instruction but I get the message "String not found" all the time, even when I search only the first 5 digits in the Product ID.

On the other hand my Product ID doesn't look like a unique number, but rather like a dummy number that ends with ..OEM. Are we all on the same OEM license number perhaps?
[Windows 8 General] sbasil:
Did you change the values to HEX before you hit the search button? It probably won't find the text strings? If nothing seems to work, send me the bios via PM and I'll take a look.
[Windows 8 General] MacArthur67:
It looks like that owners of the X80HD are on the same Windows 10 key (37GNV-YCQVD-38XP9-T848R-FC2HD). I'm not sure how that works from Microsoft's side, but it seems to be some sort of a universal OEM key tied to the X80HD hardware and OEM Activation 3.0. Also there are no traces of that license key in the BIOS file so the key must be stored somewhere else. Or it's encrypted somehow. That would mean that I can share my BIOS backup with any X80HD owner as our BIOS should be exactly the same. On the other hand there is also something called Windows (BIOS OEM Key) according to NirSoft ProductKey, and as of now I don't know if that key is shared also. That key is stored in the BIOS and could possibly be unique for each license. Therefore I have taken that key away in the BIOS .bin file that I share below. I don't know how to obtain that key as it's not printed on the original box that the X80HD came in. Maybe you can skip that and go to Windows Settings -> Activation and fix that after installation (if you have another key). Otherwise the BIOS file has to be edited in a hex editor before you flash it. Use sbasil's X80H Toolbox for that for example.

Here is the BIOS file:

https://mega.nz/#!RVRmhCjY!rkBaiFjAtqLRRdOmRq1fUO86H6S2t-kf9dLxQ5wVVjw

The Windows (BIOS OEM Key) starts at line 715FFC

I have replaced my original key with a dummy key: ABC01-ABC01-ABC01-ABC01-ABC01

If you use XVI32 Hex Editor you see that key in clear readable text in the right field of the editor (hex in the left field).

Teclast x80hd windows 10

Hi guys, sorry for my bad english i'm italian...i have a Teclast X80HD with dual OS ( Windows 8.1/Android 4.4) and i want to upgrade to Windows 10! What do you suggest? There are problems with drivers, touchscreen and so on? Thank you so much :D
[Windows 8 General] MacArthur67:
Follow the method in post #1216 in this thread for example. If it fails you can flash a whole new Win 10 (link in my post #1271). Also check and write down your Windows 8 key and Windows (BIOS OEM Key) according to my post #1322 to avoid license key problems. Make a BIOS backup in X80H Toolbox before you start perhaps.
[Windows 8 General] mr_kaboom:
Thanks for your bios uploaded.

With my old X80HD (i have 2, one die with bios and one go straigh to bios when press power on), before it was going to dead, I used a program that can read the key and that key start with A***.

Ps: Do you have any idea with my X80HD, the one which go straigh to bios when press power on? I want to consult from you before edit and flash your bios you uploaded. It cant boot from usb (to install windows), include choose in Boot Override. Sometimes I disconnected the battery, waited for a day and reconnected again, it boot to Android luckily (about 10% lucky).

---------- Post added at 05:15 AM ---------- Previous post was at 04:49 AM ----------

After update windows 10, my tab have a bit stuning. But after check and install a new update package, it work very well and smoothly but storage is going to low if you don't clear Windows.old. Note: Don't clear it if you not sure about use windows 10 or not beacause you can downgrade to windows 8.1 again if these are any problem. You can force update to windows 10 with instruction from a Vietnamese site.

Anyway, I have a warning for you: Don't try to install Windows 64-bits. It will break your bios and hardbrick your tab, of couse.
[Windows 8 General] shiggs1988:
Sorry for the delay - been AWOL on here for a while!

I downloaded the stock firmware through a mirror on the 4PDA.ru forums - someone had posted these in a sticky for the x80h.

Baidu downloading is a pain so hopefully this will help!
[Windows 8 General] MacArthur67:
Thanks, problem solved while you were AWOL! :)

Lollipop

Hello guys,

i have FB5M x80h running Kitkat 4.4 and windows 10,

i tried changing the DPI to 180 but after a rebooted my tablet and choosed android, it stuck in the boot logo,

i tired changing it back to 160 successfully by connecting it while it's stuck, but it didn't solve the problem,

any ideas ?

EDIT1 :

it actually reboot after a while, to the boot selection mode,

windows starts normaly,

android keeps rebooting :rolleyes:
[Windows 8 General] cruizgaray:
Since two weeks ago, my x80h charges until 92%, in Android and Windows os. Any advice?
[Windows 8 General] mr_kaboom:
Go to post #2 and read the Battery calibration link. Hope it work for you.
[Windows 8 General] B1sakher:
Anyone ?

Edit1: i solved it by instaling a new OS, i choosed LewaOS

maybe after a while i'll try Lollipop
[Windows 8 General] MacArthur67:
Did you brick KK by changing DPI? How did you change it? What method? I have been playing with the DPI and trying many different values and don't see how that could cause a bootloop? I gave up my DPI changes because no matter what value I set the same photo viewed in Win 10 always looks better. Strange.
[Windows 8 General] B1sakher:
i know right? i used X80H_TOOLBOX the last version to do that.

Now i fixed it by instaling Lewa OS, while it's stuck in boot logo.

Lewa OS is sharp, better than the original KK i think, DPI of lewa is 212
[Windows 8 General] sbasil:
If you used the Toolbox to install Lewa, the DPI is 160. The original DPI was somewhere around 212, but it looked way too clumsy, so I set it to 160.
[Windows 8 General] B1sakher:
i didn't know that,

by the way thank you for the toolbox !
[Windows 8 General] dr.diggler:
I tried to upgrade Windows 1511. Get always error in SYSPREP. Anybody else has this? Could be that teclast os switch which has some thing to Do at setup in sysprep.
[Windows 8 General] oile:
How did you update it?
[Windows 8 General] dr.diggler:
Downloaded image and created bootable usb stick. Total progress always stops at 40 percent. Driver install (sub progress) always stops at 23 percent. I removed os switch and try again now..

Normally this thing is done with windows update. But im tired of always load 2 gigs and fail.

Update: not working. Seems that i have to Do a fresh install to get this upgrade. Will Do this when i have not hing else to Do :D
[Windows 8 General] B1sakher:
By the way, do you recommande LewaOS or Lollipop beta ?
[Windows 8 General] sbasil:
I'm using LewaOS, but I don't know if it's any better than the LP beta. In my opinion -Yes. :D Should we ever be so lucky that Teclast would actually release the final version of LP, I'd probably install it. But as for now, the current LP beta was too buggy and I hated the blurry screen with KitKat.
[Windows 8 General] flywithlovepls:
hi

anyone know how to fix my prob :

android is missing from os selection :(

edit : fixed
[Windows 8 General] chillout23:
How? If you can say :)
[Windows 8 General] skrewie:
How is lollipop on this device ? Blurry screen and bad sound as KitKat? Never again i buy a teclast produkt...... So bad support, lika a joke !
[Windows 8 General] petricss:
Has someone bought the X80HD version lately, and can confirm that they're using no name emmc with such a slow performance as reported at post #824?

I would really appreciate if another crystaldiskmark report can be posted here.

Researching the differences between X80H and X80HD, I've came to the conclusion that the latter is having a lower rated battery (4500 vs 5000) and a plastic back casing. But then I don't understand why the same bios/windows version won't work on both of them. This makes me think that there're differences in HW as well.
[Windows 8 General] flywithlovepls:
anybody know windows 10 version for this device?

is it 10 home 32bit?

thanks
[Windows 8 General] sbasil:
Yeah. Windows 8.1 with Bing upgrades to Windows 10 Home (32bit).
[Windows 8 General] carpenick2:
model X80H, so much difference compare to screenshot at post #824

bought about a month ago...so far no problem and I love it :D
[Windows 8 General] eureka9092000:
Need opinion, is it possible to create a switch that can cut off electric current into battery?Maybe cut red positive wire and put small switch for it. The purpose of it is to retain battery life and use only usb-powered source. As we know, use tablet while it charging will reduce battery life dramatically.Just like a laptop, we pull out battery, which is cut off current into battery and use only external source. ??
[Windows 8 General] dr.diggler:
Hi. Should be possible. Tablet is easy to disassemble
[Windows 8 General] MacArthur67:
I have a X80HD bought in September. It has a Biwin EMMC. Not as fast as the ones in X80H, but a lot faster than the one in post #824. See attached Crystal Diskmark screen dump. For photos of the EMMC in My X80HD go to post #1304.

There are some minor hardware differences between X80H and X80HD. The screen, or actually the digitizer, is different. I flashed the LP Beta for X80H to my X80HD and it works fine, except that the digitizer is mirrored/reversed somehow. Tap upper left on the screen and it becomes like a tap on lower right instead. Very weird. So, in terms of hardware the only differences I know of are the EMMC and the digitizer.
[Windows 8 General] sbasil:
Hmmm...Interesting...I had to try something and so I did... :-d Just flashed Mirek's V6 x98 Air II ROM (LP) on my x80h and bloody hell -- IT WORKS! :D Well, almost. Had some system error messages after first reboot, but fixed them by lowering the DPI. The touchscreen isn't accurate (maybe 3cm off), but I'm pretty sure it's fixable. Maybe someone wants to take it even further and build a working "@mirek190 -wannabe-ROM" for x80h? I dare you!

edit: quadrant scored around 19 000 on this ROM
[Windows 8 General] chat1978:
I'm a bit offtopic

The tablet is getting decommissioned.

For the glorious effort of this amazing device here is the history. For the fast and the serious you can skip to the end for the question

What I liked?

The big screen

The performance on Android

The dual boot although I never actually used Windows. Interesting though to investigate the experience

The HDMI option

For around 100euros my respect.

And my question is what would you suggest as a similar device to get as replacement?

I would like to have one with Win10 but only if there is more memory.
[Windows 8 General] sbasil:
If you don't mind the lack of an HDMI port, Chuwi's Hi8 is probably a pretty nice 8" tablet. Faster CPU (Z3736F), a full HD screen (1920x1200) and also has both OSs (W10 & Android). The price isn't bad either (should be around $85-95).
[Windows 8 General] chat1978:
Nice although I think I would pay the extra back for 2GB more just to see what Win10 can do.
[Windows 8 General] sbasil:
You won't be getting 4GB Bay-/or Cherry Trail tablets anytime soon for $100. :)
[Windows 8 General] chat1978:
That I understand but aren't there equivalents for 4GB this maximum price 150?
[Windows 8 General] DanielDEV:
So... I have this tablet for 5 months and I hate it. Not accurate, bios bugs, speakers don't work well etc...

Last time I buy from Teclast >.>
[Windows 8 General] sbasil:
I haven't noticed one (yet), but this one comes pretty close (with a bigger screen). The WUXGA (1920x1200) resolution works pretty well on a 10" screen. Not that much wider than FHD but enough to make it better on portrait mode.

[Windows 8 General] chat1978:
Thanks sbasil but I thought maybe someone had direct comparison experience.

I'll look further on the specifications front.

Thanks again and sorry for the off-topic for the rest

I love my Teclast, OK it isn't perfect the battery 7% issue is a bit of a bind but you get used to it. So anyone reading this thread don't be put off this is a great looking device and the dual boot works well especially on windows 10.

Has anyone come across a Dual Boot Phone? I am running a bit of an ebay business and find the ebay android app virtually unusable. So I would love a phone with dual boot, Has anyone come across one>

Fixing blury screen on Stock Android 4.4

Hello everybody, I've been out of this forum for a while.

Well, to the point.

I was searching for a way to fix the blurry of the stock android rom, I found out that Chuwi users had the same issue and fixed it by flashing a boot.img.

So I tried flashing, but using the LeWa boot.img into the stock, and I think it worked!

In a nutshell, replace the boot.img of the Stock 4.4 with the one I've attached to the post.

I can clearly see the difference when using certain apps (being Settings and Xposed Installer the most notorius)

So, if you want to, try this fix and I hope everything works as fine as it has been working for me.

Here´s the boot file https://drive.google.com/file/d/0B2iYnMM5TaIUSUM4RG5aUGFGOG8/view?usp=sharing

Issues so far:

- Camera not working

- No Audio

Update:

Since audio and camera were not working, I reflashed stock boot.img, problems were fix and blurry it's still gone.

I'm going to research more on the matter

I'm having an issue with touch screen, when i touch the screen in the middle - it doubles, pic related: cs4-1.4pda.to/7315265.png

Am I alone with this? Is there a fix?
[Windows 8 General] oeriel:
I have Teclast X80H - only Windows 8.1 OS. It works great, only disk (EMMC) is Biwin, so it's one of the slowest. I have a cable - something like USB HUB, but it allows to works as USB HUB (position 1), USB HUB and charging (position 2) and only charging (position 3).

Yesterday something strange happened. I've connected it to charger, in position 2 (charging and USB HUB) while working normal. Tablet was switched OFF to sleep, as I defined it - as always. But I realize, that it have problem with charging. When I connect charger it's Windows icon not changed to "plug" and not charging tablet.

Moreover - when I connect OTG cable to it ... it charges other devices through this USB port, like my smartphone or powerbank!

It looks like power direction was reversed. BUT! It's only when Windows is loaded. When I switch off tablet (shut down Windows OS) then plug charger it charges it. But next strange - it charges it to 80-81% and no more. What happened, how to repair it.

Micro USB port seems to be ok, not loose, all devices connected through OTG, HUB works as normal. Charging is also OK, but ONLY when device is switched OFF (not in sleep or hibernation mode - it have to be switched OFF).

This OTG USB HUB (with 3 posiotions switch) works ok, because I've tried it on other devices.

Can you give me some advice?

To sum up:

- Teclast X80H - Windows 8.1 with Bing

- USB charging only when tablet is switched OFF,

- no sign or icon change when connected any charger (tried many) and no charging in Windows,

- microUSB works ok, not loose slot, all pendrive or disks works ok through OTG,

- charging, when device is OFF goes only to 80-81% - charging time is normal, but durring all night it will not charged more than 81% - maybe some wrong information about battery size and then it see 81% as 100% of other value

- connecting OTG cable or normal cable to i.e. PowerBank, this tablet can charge other devices, so in Windows it works as ... powerbank.
