Hi, I think you need to boot it to os switcher with pressing power + vol up buttons.

And there in the left corner you should have a checkbox to tick :) If it's ticked then it will ask you always which one OS to boot into.

As for Windows 10. I'm testing it on my main PC already, I decided to upgrade a week ago. First thing the option to upgrade with saving all your data, apps and configuration - works perfectly I didn't lose any file or config. I just started My PC with Win 10, all other configs were the same as the old win 8.1.

For the one week I am using it I have faced only one unwanted restart ( I think that it was an update - but the fact is it restarted without any signal or pop up )

Apart from that all seems to be working. As per performance I din't face any much difference, maybe a bit slower - but it is still a technical preview so I hope that can change only for better. My PC is a bit old ( 6 years) so its not a power monster but I am able to run some games and I didn't find any difference by now. If you have any concerns or questions you can ask I will try to answer :)

I know that this is not really related to x80h but I will be installing the win10 on it soon as I see it works good on my PC :)
[Windows 8 General] Malkatraz:
sbasil, did you ever figure this one out. I have an fb6m device, and was playing around with it trying to get Windows 10 (10166) to boot from usb. Saw someone in this thread mentioning formatting the small partition on the drive using a partition manager. Well, my X80h had two small partitions and I formatted both. After a restart, couldn't boot into anything. Always looped back to bios. Couldn't get to boot loader (I have previously removed android so that's not an option anyway), and clicking on anything in boot override does absolutely nothing.

Tried the following:

GPT

W10 32 bit - no boot at all

W8.1 32 bit - no boot at all

W8.1 32 bit with boot64.efi - boots from USB but immediately BSOD's

W8.1 32 bit with boot64.efi renamed as ia32.efi - no boot

W8.1 64 bit - boots from USB but immediately BSOD's

UEFI

W7 32 bit - no boot

W7 64 bit - boots from USB, and is the only way I have even got the Windows installation white on black progress bar to start. but hangs when progress bar reaches 100%

I've been at this on and off for a couple of days. Have tried suggestions in this thread using diskpart to create the USB, as well as rufus and the win7 USB tool. Also tried the WINPE+NTFS dual USB suggestion (doesn't boot).

Again, the only option I get is the bios. Even though the SSD still has Win10 on it (an older version - was trying to upgrade to 10166) I cannot boot into it and the machine doesn't even acknowledge that the installed OS exists.

I understand it wasn't smart just randomly formatting partitions, but I would love it if there is a reliable way of booting into a Windows OS, of any kind.
[Windows 8 General] Braccoz:
make a bootable pendrive using REFInd. then use that to boot another pendrive/usb dvd with the 32 bit 8.1 installation on it. delete all partitions and let the installer create them automatically

I've tried this many times now and no it doesn't work.

Is it suppose to work? anyone else got this working or were you just guessing?
[Windows 8 General] dr.diggler:
Of course it works.
[Windows 8 General] dr.diggler:
sbasil,i know you´re busy or maybe not interested in developing stuff for this tablet because you´re working on chuwi hi 8 or something else, but could you kindly keep us up to date if a final lollipop 5 or a new lewa or a stable MIUI rom will arrive? I have no experience in making things like play store working etc.

That would be really nice :) Thanks
[Windows 8 General] n_chuck:
Late for me

Hope I've seen this before, did install Xposed manually in the tablet itself... got it working though.

Thanks for the script, will use if I need it later
[Windows 8 General] aerc:
Enyone try this? Can share some pictures?
[Windows 8 General] sbasil:
I'm on summer vacation which is the reason I haven't been very active lately (busy enjoying the cold Finnish summer). :p Haven't ordered Chuwi or other tablet so far either. But I'll keep you up to date if I bump into a new version of MIUI or LP. :) W10 seems to run really nice on our little x80h btw.
[Windows 8 General] sbasil:
I flashed my x80h's bios which fixed all booting problems.

Battery Calibration.

I calibrated the battery once using page 2 method and all went well. So I was playing football manager classic on android 5.0 beta, and yes, in case you wondering, it works well. FM classic on android is supported on this tablet. Forgot to off the screen when I was in the supermarket and no prizes for guessing, the battery died.

I tried to charge full after draining on android, battery didnt calibrate, must it be done only in windows? Currently draining the batt out on windows and any solutions to this battery calibration fix?

Lesson learn: do not drain the battery flat when battery is calibrated.

---------- Post added at 10:58 AM ---------- Previous post was at 10:48 AM ----------

Didnt occur to me when I switched back to android. Try to recalibrate batt again, reboot several times to windows first and then switch to android, reboot, shut down as android and then reboot into windows, it should still show 32+++mwh instead of 16,336mwh on batterybar tool. if it still appears, recommend you reflash bios and redo the calibration steps.
[Windows 8 General] perche1:
any recomended rom for android?, android 5.0, lewa or 4.4.4, miui?
[Windows 8 General] n_chuck:
My opinion

I'm currently using Lollipop, so far so good.

The only issue, well, "issue" is that Instagram didn't work (I don't know if it was only for me), but leaving aside that, it behaves pretty neat for me (it's also crisp and clearer than stock (for me) )

Running it on a F6BM
[Windows 8 General] n_chuck:
(Solution?) Remove extra buttons on Lollipop Nav Bar

I don't know if its posted here, but there are some keys in the build.prop to disable Screenshot, Vol +/- and Menu buttons on the navbar.

They begin with the keyword "custom"

They have a significant offset but at least they doesn't show up anymore!

Mount Android Partitions in Windows

I hope i'm not spamming this thread, just wanted to give out as much as I can and help others with little stuff that they might find useful.

Paragon EXTFS for Windows has worked wonderfully, allowing me to mount Android FS and others, where you're able to modify without issues (at least I've messed up a little with the System FS and no problems so far), and the best of all, it's Free (after a simple registration on their website to obtain the key and license)

Here's a snapshot of the mounted volumes.

[IMG="Snapshot"]http://i.imgur.com/v0AckZx.jpg[/IMG]

The ones that matter for me are the 2GB and 7GB, because those are System and Userspace.
[Windows 8 General] lemuel95:
Hello, thanks for this, i was waiting for this so much time, what app you use for modify it?
[Windows 8 General] Sean29:
I think I may have found a solution to the battery calibration issue. Battery stats need to be deleted. I used advanced battery calibration app on android os, once process done, switch device off and charge to 100%. Currently doing another verification to see if it is confirmed.
[Windows 8 General] n_chuck:
How to do it

Actually there are many ways.

If you're root, get any root explorer (Total Commander, ES File, Root Explorer...)

Go to /system/, there you will find an archive called "build.prop"

Then just search for those strings that appear in the pic and change them to "No"

If you're asking about the app in the pic, it's called 3c Toolbox

---------- Post added at 07:02 PM ---------- Previous post was at 06:58 PM ----------

What worked for me was:

1. Full discharge

2. Charge powered off

3. when fully charged, boot to android with charger still plugged - Here my tablet showed a 80% charge, even when in the screen before power showed a full.

4. Let it sit and charge a little more if its lower that 100%.

if you have dualboot

5. Boot to windows and repeat the process of check charge and charge if lower than 100%

I did this once, then I just did everything except step 1 a couple of time and now my tablet is up and working with a good battery meter
[Windows 8 General] mirito:
Try this to confirm your method :

1. use all 5 steps as you describe

2. boot windows with 100 % battery, measure capacity in mWh

3. boot android, measure capacity in mWh

4. return to windows, if all works fine measurement should be ~ as step 2

I have no problems with battery when using windows, but once i've boot android and then return to windows, calibration goes to hell
[Windows 8 General] n_chuck:
I'll measure asap, but by now I can say that the method has worked pretty well for me. I've been switching OSes constantly, testing with SystemUI mod (without success) and I've seen a consistent battery discharge rate and measuring.

Let me see if by noon I can get you measures of MWh

I've attached my Powercfg report, I hope it's useful for you

how to upgrade to windows 10? i dont have enough free space

can use the microSD ?
[Windows 8 General] Sean29:
Windows 10 is out and I am prompted to upgrade, is it safe to upgrade on the tablet?
[Windows 8 General] Mouratti:
Good question!

I love to update to Android 5, but i dont know, how to do and how windows beahavior.

I use more android, but some times need to use windows.

If anyone can provide a step by step, to update android and windows to 10, will be great.

Come on gurus :)
[Windows 8 General] sbasil:
Install Windows 10 the same way that you would install Windows 8.1. There are several instructions available on this forum.
[Windows 8 General] Mouratti:
Ok thanks!

I did not read all forum yet, but can we install like on normal PC, pop- up appear and install!?
[Windows 8 General] mirito:
Quite, but when looking at design capacity i can say that 15,580 mWh is not right value. Probably when switching between OS those values somehow gone wild, cause right value is about 26,800 (2015-07-25 16:36:45 in your report). Have you switch to android in 17:29:50? Capacity drops from 74% with 23,000 mWh to 70 % with 10,906 mWh.. which is not normal and battery should freeze at 7 % for couple of hours.
[Windows 8 General] Reasec:
I dont know why this tablet is so popular when its only 8USD (92USD) cheaper than Onda V891W? Onda has FHD display, and Teclast only has poor 1280x800. Anyone enlighten me? Thanks
[Windows 8 General] n_chuck:
Like I told you before, I constantly switch between OSes,

Now down to the measures:

This tablet (at least mine) has a 4400 mAh Battery rated at 3.7v (opened it up past week due to buttons)

Using this page says that the battery should deliver 16.28 Wh, what seems to approach closer to my battery report.

About the 7% thing, I don't know but that sounds like a bug to me. For me, my battery will continue normal discharge until dying (thing I don't let happen, because it messes bad with Lithium batteries' life)

Also, don't expect similar discharge rates for this or any device, everybody uses them quite different.

By the moment, I don't have any other "PC" that this, so I use coding IDE's, web browsing, VMWare Player virtualizing debian and other stuff, so that can explain why battery goes down like my country economy, hahaha.
[Windows 8 General] mirito:
Good quality build, metal back dual speakers for X80H, hdmi and for this lower resolution - better performance in games (if play)
[Windows 8 General] sbasil:
It was out among the first cheap baytrail dualboot tablets (was it?)? :D Where'd you find V891w for $100 anyways? At Geekbuying it costs > $160. Chuwi also has some interesting alternatives for x80h. Chuwi Hi8 and Vi8 ultimate both cost around $90. Hi8 has a 1920x1200 screen, Vi8 1280x800. Both have faster CPU than x80h (Z3736F).
[Windows 8 General] Reasec:
On aliexpress for 102.99 with free shipping. Chuwi hi8 looks better than onda v891w. (Faster cpu) and its only 99.99. Chuwi actually looks like ultimate choice.
[Windows 8 General] n_chuck:
Well, shame on us for getting this tablet instead of any other better out there ;) *insert shame shame meme here*

But on a serious note, I don't know why it's so popular, I just bought what was to my reach (because at the time I bought it, was the cheaper, including shipping and taxes).

For me, by now, as the only Windows 8.1 tablet I've ever used, it's pretty useful, enough for what I do and a little even more, it feels solid with his metal backplate, 32Gb may be not enough for the dualboot setting and 1.3Ghz to 1.8Ghz may not be the fastest you can get, but hey, I'm using it for work, not games, if I want to game, Why not get a decent Desktop PC with an i7 or FX 8? (You know, for someone of us, money isn't a commodity)
[Windows 8 General] Puffstar:
For me the HDMI out was the decider over the V891W
[Windows 8 General] Reasec:
n_chuck: its not a shame that you bought telcast, its just outdated (but this is a thread for telcast, so its just my problem :) ). Puffstar is right that both Onda and Chuwi doesnt have HDMI which can be a dealbreaker for someone. I like chuwi hi8 for 2.16GHz CPU and FHD screen, it looks like that its a very good tablet and its for 92.99 on gearbest. Do you have any other brands/models to look for? Im pretty new in this area.
[Windows 8 General] n_chuck:
I was just kidding, hahaha. Yeah, it's kinda outdated but for me it delivers ;)

About brands, well, It's china, new brands come in, others go out, so the best would be to stick to those and check a lot of reviews, but remember, there's no better point of view that the one you make, and it's hard to do one because we don't have access to the device itself until we have bought it! So keep on your search and see what seems useful for you, at least you can take my word that the SoC this tablet has, behaves pretty well in both Windows 8.1 (10 also) and Android.

[MENTION=4199302]sbasil[/MENTION] Hey, Did you have a problem with Windows 10 and auto-rotate? I just did an upgrade and it doesn't seem to work, everything else seems fine, i'll be posting pics soon.

Update: Here a couple

Use the x80h toolbox for win to fix it (page 2/sect-4 --> fix the screen rotation problem). http://xdaforums.com/showpost.php?p=61067632&postcount=821

not enough free space
[Windows 8 General] n_chuck:
Installing/Upgrading Windows 10

As far as I know, you MUST upgrade in order to get the Windows 10 free, this is what I did.

You wont be booting from the stick

Things needed:

1. 8Gb>= USB Stick

2. 16Gb>= SD Card (Installer asked for 9.00GB free on any drive, I had 10Gb on my SD so I used that)

3. Windows 10 ISO (Use Microsoft's Media Creator Tool to download an ISO, remember x86, I haven't tried with x64), preferably download Home version, to avoid issues. I did mine with a W10 Multiple Editions ISO I got from my university Dream Spark, but with MS Media Creation Tool only single versions are available, as far as I remember.

4. Fully charged tablet (Did this with 60% charge, enough but netter to keep this safe)

Before anything, create a recovery drive for the tablet and save the partition in case you don't have another USB Stick for the process.

I don't know if any of this steps aren't necessary, I was too sleepy when I did this and it worked, so If you have a better way to do it, feel free to post/link to it ;)

Steps:

1. Make bootable USB with W10 ISO (or just decompress the iso on the stick)

2. Run the Setup form the USB on Windows

3. Choose whether to keep files or do a clean install (I did the second)

4. It'll ask for stuff, mine asked to reinstall English language (because I downloaded Spanish W10 and my Tablet was in English)

5. It'll ask for more space, there you have two choices, use the last, that's to choose a drive with enough space, select the SD Card.

6. Accept and proceed. Wait until it boots to the Setup Screen and you'll be done :D

Troubleshoot

Sbasil's Windows Toolbox

Fixing Rotation (thanks sbasil for your tool)

Download Windows Toolbox and choose the Fix Rotation, it should work and you should have the rotation toggle in the notification area.

Fix Camera (if it doesn't work)

I had an issue that my camera's weren't working, so in case you have the same issue, reinstall camera drivers, the ones you can get with the Windows Toolbox (or if you would like, reinstall all the drivers, but remember, if ain't broken, don't fix it)

Now the cameras should be up and working with the stock camera app.

After that, recovery partition will be erased and merged to the normal C: partition, because W10 won't install like WIMBoot (as far as I've seen, If I'm wrong, correct me ;) )

So you'll have a C drive with ~8Gb free or so (check my previous post for picks)

That's it, that what I did.
[Windows 8 General] cruizgaray:
Thanks for the tutorial. I'm using dual boot, any consideration to keep the android partition?

Best regards
[Windows 8 General] n_chuck:
I'm also dual-booting, and I can confirm that with my method, Android partitions remain intact, I can still switch between OSes :D

Just to show you, here's a recent screenshot to prove Android is up and running ;)

[IMG="Recent"]http://i.imgur.com/CLIQYTv.png[/IMG]
[Windows 8 General] cruizgaray:
Perfect. And which version did you install?
[Windows 8 General] n_chuck:
If you're asking about Android, it's Lollipop, foind here in the forum.

If you're about Windows, I did the upgrade with a Windows 10 Multiple Editions (It contains Home, Pro, Education) and by default it upgraded to Windows 10 Home.

I forgot that little detail on my post, gotta update it.
[Windows 8 General] cruizgaray:
I followed your tutorial and installed Windows 10 without issues. I feel a little stupid but the screen doesn't rotate and I can't find the setting as I do in Windows 8.1.

Thank you
[Windows 8 General] n_chuck:
As [MENTION=4199302]sbasil[/MENTION] mentioned, search here for Windows Toolbox and do a barrel roll!!

Just kidding, just download the Toolbox and search for the Fix Rotation, it will install you the driver of the Accelerometer and add a reg key to enable it.

When you've done it, you'll find the rotation toggle in your notification area, beside all the other toggles.
[Windows 8 General] caravanman:
Just tried the upgrade using a micro sd for the external storage, tablet is now goosed!

well it's stuck in a loop saying it is restoring to previous version of windows and the boot logo ad infinitum

Oh bugger!
[Windows 8 General] n_chuck:
Did you keep the USB plugged in? I think my intall did read from it, because it was showint IO activity on the LED during install, besides using the SD

Also, in the upgrade, did you do a clean install or upgrade? What kind of SD were you using?

Did you make the recovery stick I mentioned before upgrading?
[Windows 8 General] cruizgaray:
You're a life saver! At first I feel it a little slow but after a few reboots it's snappy. The only thing is I can't install my bluetooth keyboard which ran perfectly in windows 8 (it pairs but doesn't connect). That's a deal breaker to me so perhaps I'll reinstall windows 8.

Thanks for your help!
[Windows 8 General] n_chuck:
I haven't tested mine, will do now and edit this to post results, and maybe if mine fails too, i'll search for a solution, because W10 surely works better in tablet mode than W8.1

EDIT: Just tested mine, it works alright, I don't know what's happening to yours.

Also found an issue, Can you test your Camera App? Mine opens but there's no image

EDIT2: Camera's working now, but I don't know if the reboot or the reinstall of drivers fixed it. I'd recommend reinstall the original drivers for both cameras.
[Windows 8 General] caravanman:
USB was plugged in throughout (for power) SD card in slot,

I did an Upgrade on 16gb Micro SD card (for extra space as requested the w10 install), which was freshly formatted, I have checked this and it has about 6gb of folders on it, presumably this is the recovery to windows 8 that that the upgrade is trying to fall back to?

No recovery made, lesson well and truly learned :o
[Windows 8 General] n_chuck:
Hahaha, well, you should've done it. But anyways, it's weird it has failed.

I think your best shot would be to reinstall W8.1 from scratch with the guides in this thread and then try to update once more, and see if that works.

Hope you haven't lost anything on the process.
[Windows 8 General] caravanman:
Nah, it's a secondary device so no great issues, will have a read, and no doubt get confused!

Anyhow off to more pressing matters, BEER

Cheers

Hi

Just got the lewaos 5 h lollipop installed but is there a easy way to root it, say via a script?

Thanks
[Windows 8 General] n_chuck:
I don't know what version are you saying, but, try with the Android Toolbox posted in this thread
[Windows 8 General] slewis1972:
Android toolbox just lists 4.4.4 to root unless I am missing a version. Got the lewaos version off this thread, a way back mind you, got to find the post but its lollipop. Not prerooted.
[Windows 8 General] sbasil:
LewaOS isn't lollipop. It's Kitkat (4.4.4) and you can use the toolboxes rooting method. The Lollipop version that my Toolbox downloads, is pre-rooted.
[Windows 8 General] slewis1972:
Got to get fed up with people, its skinned to look like lollipop, that's for the prompt. Time to download the on In the toolbox.
[Windows 8 General] n_chuck:
As far as I remember, it looks like Lewa, not Lollipop. Also in the info it says 4.4.4.

Lollipop version in WToolbox comes pre-rooted
[Windows 8 General] cruizgaray:
My camera doesn't work either. My keyboard is recognized as Bluetooth 3.0 Keyboard, how is yours? How do you reinstall the drivers? Sbasil tools magic again?

Best regards

Edit1: I did an update and now my camera works. Struggling with the keyboard yet...
[Windows 8 General] perche1:
i install android 5.0 in my tablet with sbasil toolbox and all work ok but i have a problem, in windows 8 and 10 , programs like battery bar and battery care report a wrong capacity , 31.160 mhw about 8200 mah, before of upgrade to android 5.0 was 16.300 about 4500 mah (real capacity of teclast x80h is 4500 mah at 3.7v).

Any more have this problem?
[Windows 8 General] n_chuck:
I really don't know what Bluetooth version is mine, I just turn it on, press Connect, in Windows I go to Settings> Devices> Bluetooth and from there I pair them up. That's it.

And yeah, the update of drivers with the tool was all that you need ;)
[Windows 8 General] dr.diggler:
My 2 cents:

I did the upgrade with ms Media creation tool. Worked fine. Only thing is that i need to reinstall things like office365.. i also realized that clean up of storage is a must. It will delete win8 recovery and i have a lot of free space now :) my Bluetooth Keyboard is also working fine. No errors atm. Can recommend. It is much more comfortable to work with touchscreen now than with win8.1. The thing is, don't Upgrade with other methods... use Media creation tool and you're done. Also force windows update After setup has completed and Do several restarts. That should solve minor issues.
