I think that Lollipop requires a 2GB system partition. If you have a partition smaller than that, it probably causes you bootloops. For that reason you need to create a bigger partition for the system which will most likely cause your Windows to vanish as well. I'd wait until the official Lollipop hits the "shells" for x80h. You could also remove some apps from the official Lollipop (beta) image and try reducing its size to 1GB (Linux --> img2sim/sim2img --> make_ext4fs -s -l 1024M -a system new_system.img sys...etc...This is just me guessing).

edit: I had to try... :) Reducing the img size by removing some non-essential apps seemed to do the trick. Lollipop starts just fine from my 1GB partition (although the first boot took several...minutes).

What I did was (used my own tool and resized/repacked system.img file):

- chose the option C (3 will be fine too, the others will erase Windows as well)

- replaced the droidbood.img manually (copied it from tools dir to _PLACE_ANDROID_HERE) (Lollipop's own droidboot.img doesn't work too well).

- erased the data partition (clean install)

---> vóela, system up and running.
[Windows 8 General] guyton100:
can you please upload modified lollipop rom for me? many people who want small android space will also benefit from it.

or is there any simple tool for windows?

if you are editing and uploading can you make it as small as possible with just basic apps?
[Windows 8 General] sbasil:
Sure. It's about 474MB (packed size). I removed many Google apps from it (download them from the store), set the default language to English instead of Chinese, but that's pretty much all what I did to it (= reduced the size). Ohh, and set lcd density to 170...everything was so small @ 160. It's pre-rooted, but the app is in Chinese, so good luck with that. Still, I suggest that you download some other launcher (Mi Launcher is nice) and an icon pack, the default ones are "blurry." I don't know if it's the latest beta, but that's all I had on my comp. :) And nope, there really aren't any good image editing tools for Windows that I know of. I made some scripts and run them on Virtual Mint which works for me. :

Here's the download link to it.

Need help,

I reinstalled windows on my FB5M dual boot tablet the space taken up by windows is about 14GB.

My android is missing, I accidentally wiped out everything incl droidboot.

How do I install android on the tablet? Flashtool cannot boot droidboot.img. In dilemma. :confused:
[Windows 8 General] guyton100:
thanks for modified lollipop. is your modified kitkat compatible with 1gb partition?

please implement your modified lollipop in next toolbox. your toolbox has made it child's play to install rom.

is there any way for charge and otg besides buying cable from banggood?

installed lollipop and xposed can not be activated. used rar from previous page.
[Windows 8 General] lemuel95:
how can i get rid of volume and screenshot keys from nav bar on lollipop?

when i adjust lcd density the nav bar moves to right, and it gives bugged
[Windows 8 General] sbasil:
Both stock ROMs seem to require 2GB for system partition (even the modified one...they both have over sized system partitions if you ask me --> over 700MB of wasted space). Lewa needs only 1GB.

I'll update the tool to show the system partition size requirements. Less bootloops that way. :)

And I'll add the Lollipop to the list when a better version comes out. The current one isn't particularly good.

edit: I tried installing Lollipop using the original image and 2GB partition....I think that it's a bit faster this way. (Quadrant 18000, Antutu 36 000).

Probably better to leave the System partition to 2GB or at least 1,5GB, especially if you're planning to reinstall the whole tablet (that way you don't have to meddle with the partition sizes and lose Windows (again) once the official LP appears).
[Windows 8 General] bushako:
Its not that easy. Youll need to decompile systemui.apk file from root. And modify the settings on your PC using apktool and such. Just Google its there somewhere.

Help

Someone help me ...

I downloaded the rom Lewa 5.0, forgot to unpack.

Do not enter more in fastboot.

It is on this screen.

o What do I do?

Sorry for my English.
[Windows 8 General] sbasil:
You're exactly where you're supposed to be if you're going to install a new ROM (that is the fastboot mode). Do you mean that it won't

enter the droidboot mode anymore? And what do you mean when you said "you forgot to unpack?" What tool are you using to

flash the ROM? Intel's flashing tool utility? If you haven't flashed anything yet, you can just shut down your tablet by pressing the

power button for 10 secs or so and it'll be like it was before.
[Windows 8 General] asjaf:
I was using the toolbox 7.3

I downloaded the ROM in Lewa site.

I installed using option C, but failed. The tablet does not work anymore with Android.

Trying to solve the problem, open the tools folder and clicked the fastboot_user file.

Erased everything related to android :(

Do not enter more in droidboot mode.

It seems that erased all

The windows operate normally.

Help me, Sbasil.

Please
[Windows 8 General] sbasil:
Try this:

- power down the tablet

- start it with holding POWER + VOLUME DOWN as long as needed (the tablet should boot into droidboot mode that way).

I had the exactly same problem the other day, but cannot remember what exactly it was that fixed it. But it's fixable, so don't worry. :)

Mine got "stuck" when I tried to install LP to a too small partition.
[Windows 8 General] asjaf:
it did not work.

Not load any Android file.

When I clicked on fastboot_user file was deleting all files Android.

Its reinstall Android?

The bios?
[Windows 8 General] sbasil:
But did you get to the droidboot mode? It's the one where there's an Android logo on the black background. I also re-flashed my bios, but I don't know if that's what solved the problem.
[Windows 8 General] asjaf:
Droidboot mode does not work.

I want to reinstall the Android.

What do I do?
[Windows 8 General] sbasil:
Well this is a longshot, but download the attachment and extract all files to the same folder and run the _efilinux-user.efi.bat from the command promt (first you have to restart your tablet into fastboot mode).

I'm just following the same footsteps I did with my own tablet. One of them must work. :)

edit: I'll remove the ADB install from the script in the next version. It might cause problems when switching between LP and KK (can't flash the user-efi in droidboot mode so it skips it. Couldn't get the tablet to reboot directly to fastboot with adb commands either, so it's better if it doesn't exist at all. Pressing pow + vol keys isn't that much trouble).
[Windows 8 General] asjaf:
Hi,

A reflash the bios, but the Android botton does not appear.

how do I appear android button on initialization again ?

Thanks.
[Windows 8 General] sbasil:
Did you run the batch file I included in the previous post? Try reinstalling Android after that (try the official Flashtool from Teclast if x80h toolbox doesn't work) . If that doesn't work, I don't know what will. I rest my case. :)

edit: the Toolbox is now updated to a new version. Bu-byee to adb-installs. It shouldn't cause any more trouble (if it caused them in the first place...but better safe than sorry).
[Windows 8 General] guyton100:
no need to reflash bios, try installing both system using guide on page 1
[Windows 8 General] JD250:
Hi. I always use Android but last days I've been using windows and updating the software but there's a problem. The tablet doesn't turn off when I touch "SHUTDOWN"... The screen turns off but the tablet rises its temperature and the battery drains... I don't know how to fix the problem :S
[Windows 8 General] sbasil:
Check your event view log and see if there are any critical errors (Windows Logs --> System & Application logs). Then try solving them with Google. You can start the event viewer either by running a command "eventvwr" or find it in control panel (under Administrative tools).

Hi,

I have got a Teclash X80H FB6M device.

I deleted Android partition with windows 8.1 disk utility when I bought this tablet. Because default partition settings 12 gb not enough for windows 8.1

Now I want to delete all of data and reinstall android4.4.4 with 4gb partition and use other big of partition for windows 8.1 bing.

How can I do IT ?

I tried install android 4.4.4 rom with intel manufacturing flash tool but setup not completed. Teclast give error as below

But its only for X80HD, would this case fit in X80H?

Someone can look a nice case for this tablet?
[Windows 8 General] EndlessRoeDeer:
Case

I have ordered a Tri-fold Folio PU Leather Case Stand Cover For Teclast X80H on Banggood site, you can check it there. There is also a not folding case if you prefer that kind of cases.

I cannot really say anything about it cause I am still waiting for the package with my teclast and the case for it.

If you want to wait I can update you once I get it :)

Just got mine, FB5M and need some quick advice:

1. Can I factory reset Windows 8 so I can set it up as English etc or do I need to reinstall from scratch? A

2. Dual boot. i have to press the volume up to trigger the options. How can I get the options automatically on every reboot/start?

2. Lollipop. Got the files from a previous post, but I am struggling to find out how to install it? Do I need to root 4.4.4 first etc

[Windows 8 General] sbasil:
1) http://xdaforums.com/showpost.php?p=60717472&postcount=726

2) when you see the OS boot menu and a check-box on the top left, put a check mark on it.

3) read the instructions (2nd post on this thread) or use this Toolbox here
[Windows 8 General] slewis1972:
Thanks for above, really appreciate it.
[Windows 8 General] sence:
Anyone solved the 7% battery issue of X80H? Did search in this thread but dint see any info on that. Complete drain of battery in windows will some times solve the issue. But once you switch to android, the battery issue comes back.
[Windows 8 General] slewis1972:
Trying to use toolbox app, but am having issues getting the Intel Android AD driver installed on pc. Installed both the Intel Android exe and isoc usb driver but in device manager still get a entry for Intel Android AD and it fails to install.

Any ideas
[Windows 8 General] sbasil:
If you have 64bit Windows, you need to disable driver signing verification. If you do not, unsigned drivers will fail to install (such as these). It will probably look like it's installing something when you have the DSV on, but it's not! Use the toolbox to do so, or do it manually. You can turn the DSV back on after you've installed the drivers and rebooted your computer.
[Windows 8 General] slewis1972:
Driving signing is off. I now have 2 entries for Intel Soc USB Driver when in Dnx mode - is this correct?

uefi firmware settings

I own a Voyo A1 Mini which, unlike the Teclast X80h, can not enter DNX mode (it is shown for 0.2 second and then it boots to Android) and USB device mode for ADB. I suspect it is a limitation of the Ami Aptio uefi firmware or perhaps some default setting should be changed. Would one of you X80h owners be so kind to provide photos of all firmware menu screens? Thanks a lot in advance for your time!

PS: I posted photos of the Voyo settings in a series of posts starting with this one You can also point out differences by referring to these in case you don't want to spend too much time on this.
[Windows 8 General] slewis1972:
Can you expand the settings. I've been messing and now have the attached but still no joy. Everytime I try and get status, get daemon not running etc.....

Try installing samsung usb drivers for android too.

---------- Post added at 02:11 AM ---------- Previous post was at 02:07 AM ----------

Guys are you having battery calibration issues on your X80H? Like draining fast to 7% and then stuck in there for couple of hours. There was a guide like in X98 air 3G, to drain the battery to 0 in windows and then charge it to full. It will calibrate the battery in windows. But once you switch back to android, the problem will come back again. I dont if you guys experienced this issue or tackled it. Please reply if you got any tips for this problem. Thanks.
[Windows 8 General] slewis1972:
Tried Samsung drivers, no go.

Just installed on Windows 7 - same issue.

Tablet is in "Entering DNX mode, Waiting for fastboot command...."

Different USB ports tried. Got to be missing something but not sure what.
[Windows 8 General] lamjah:
How I solve this issue

Hi My Friend, I had the same problem like yours with the same device FB6M and USB not showing in boot override. This is how I solved it/

1. Download and install minitool partition wizard in your teclast device

2. Open minitool partition and format the other small partition on your C drive

3. Restart your device, it will automatically reboot in bios mode and you will notice that evering is removed under boot override;

4. Now insert your windows installation usb key in the device (teclast OTG port) and restart.

5. It will begin the installation process and your bios is repaired too.

Hope it will help

Thanks

All of a sudden everytime I turn my tablet off it reboots, has anyone else had this issue?
[Windows 8 General] guyton100:
can someone upload Le Frog OS Extreme optimized version from bbs?
[Windows 8 General] Callmenobody:
Heads up!

A heads up!

I installed the new firmware update on my new and unmodified X80H (downloaded via pre-installed update app) and when I later booted into windows for the first time after updating I got a blue screen with som chinese symbols and a sad smiley ":(".

After that the screen turned black and it is now completely dead.

It doesn't charge, start in any mode, doesn't show any start up animations or get recocnized by a PC when connecting it with a USB.

Well, it worked for a week at last :(
[Windows 8 General] EndlessRoeDeer:
Thanks for telling this, I should get mine new Teclast x80H today, wanted to do this update as a first thing after booting it up.

Now I wonder what should I do? Install some other version of Android using Sbasi's toolbox ? Any recommendations what Android version works most effective ?

I would love to have Lolipop but it's still beta version right ?
[Windows 8 General] sbasil:
Did you try holding down the power button for about 10-15 secs? Sometimes my x80h has frozen (black screen, nothing else) like that after trying to reboot it, but the pow button trick has revived it every time.
[Windows 8 General] Callmenobody:
Wow, it took around 30s for it to start but it's still busted.

I have vertical stripes over the screen, it keeps flickering and I got like a black frame around the screen but with round edges, as if you wipe of a dirty window with a rag.
[Windows 8 General] sbasil:
Does your computer (Windows) recognise the tablet? You could try re-flashing the firmware (bios?) with the x80h toolbox or manually. Just choose the right version of the bios (fb4m, fb5m, fb6m etc).
[Windows 8 General] Callmenobody:
Yeah, the explorer says X80h (FB6M) so I guess so :)

There is another problem which existed before though. Rebooting from Android is no problem but rebooting from Windows, or switching OS from Windows to Android, turns the tablet unresponsive for somwhere between 5-10 minutes.

So the question is if I should start to try and fix it by myself or just have the store replace it.

To be honest I didn't read to much when I registered and thus missed that this is i forum for professionals. I can find my way around a computer and follow tutorials but a programmer I am not :)
[Windows 8 General] sbasil:
If you bought it from a local store, it's probably not a bad idea to get it replaced there. :) I got mine directly from China and it would cost more to send the tablet back than what it's worth.
[Windows 8 General] Callmenobody:
Yeah, China has it's moments but this time I spent a little extra and bought it from Hongkongeek.

I'm from Sweden so I hope that the "Free return", "1 year warranty" and "German warranty center" is not BS :)
[Windows 8 General] EndlessRoeDeer:
Could someone confirm Callmenobody's problem related with Teclast update app ?

I want to try not destroying my new tablet in the first day of usage :)
[Windows 8 General] Callmenobody:
This is really strange.

It has been connected to my PC at work for some hours now and the stripes and "frame" is now gone. Exept for a slight flickering it is as it was upon arrival.

I still have to wait a few minutes after exiting windows before I can restart the tablet but that is a fault that was there from the beginning.

Is there a reset function that restores it to factory settings on both OS?

Perhaps that can solve the problem with waiting after exiting W8
[Windows 8 General] sbasil:
You could reinstall both OSs, but other than that there really isn't a "real" factory reset option. The screen flickering and those stripes could indicate a hardware problem rather than a software one, especially if they've been there since the get-go (screen flickering, stripes etc. --> low voltage -->faulty power supply/circuits.....or something). :)
[Windows 8 General] Callmenobody:
Ah, to clarift:

After the update I got the stripes, flickering and frame-thing.

Now evereything exept a slight flickering is gone (back to normal).

I guess that I need to deplete the battery to see if the problem comes back.

By the way, this is how it looked, with some good glasses you can see the black shading/frame around the corners of the display
[Windows 8 General] sbasil:
You should send that photo to the place you purchased your tablet from and ask if it's normal. :D Maybe they're willing to replace it with a new one without any drama. :)
[Windows 8 General] Callmenobody:
They haven't replied to my first contact yesterday but after a few more hours last night the flickering dissapeared as well.

The only thing left is the initial wait-5-min-for-reboot-from-windows-error.

Just so you know what has happend for future reference :)
[Windows 8 General] dominik325:
I had a similar problem when I replaced a display on my brothers Nexus 7, all sorts of flickering and those same lines on the screen, but it all disappeared in a few days. I think it's because of the poor quality of the Chinese displays. It might also be the poor connection of the LCD ribbon cable inside the tablet. You might want to re-seat it and maybe even clean it with alcohol to make sure it won't cause it again.
[Windows 8 General] EndlessRoeDeer:
I got my package :) Teclast came with both OSes alredy in English, that was nice. What really suprised me was that in Android I had installed playstore already and it was running out of the box with no issues :)

I didn't use the update app as I was scared that it may cause some troubles, but I find the initial Android 4.4.4 Kitkat really great and smooth. I need only to remove the Chinesee apps, is here a list of the app that are not needed and can be uninstalled ? Cause I don't want to remove something important :) Thanks in advance for responding to this part :)

One more thing about the case. I really don't recommend it, at least in blue color. It is really glossy, looks like a case for a girl or a child, but I cannot complain on the way it's made. It holds tablet nice. Tri fold is ok, magnets not hold it realy strong but for that price if it woudn't been so glossy I would tell it's a good choice.

Hi guys

If i install android on FB4M version,did it become dual boot?
[Windows 8 General] shiggs1988:
I'm having trouble downloading the official images for my X80HD at this link:

http://pan.baidu.com/s/1mgBsG56#path=%252F

Any suggestions, as I don't have a chinese login? Many thanks!

N.B. I know the x80h files have been mirrored on OneDrive but these aren't fully compatible due to hardware differences, namely the touch screen.
[Windows 8 General] sbasil:
No. You need to flash a new bios in order to make it "dual bootable." There are instructions on this thread to do so, but be aware that you might end up bricking your device unless you know what you're doing.
[Windows 8 General] taranum:
Thanks sbasil for the reply.After flash new bios only need to install android then it will become dual bios?or need to fresh install windows 8.1 back
[Windows 8 General] sbasil:
You (probably) will have to reinstall both OSs, if the SSD is partitioned for one OS only (I assume it is since it's FB4M?). Remember to make a backup of your Windows product key before you flash anything or you will not be able to re-activate Windows. There are plenty of instructions here, read them through before you decide to do anything.
[Windows 8 General] peppe24:
doesn t work

haven´t heared anything new related to lewa OS or a final android 5.0 version. Is there something new tested by you, sbasil?
[Windows 8 General] sbasil:
Lol, no, I'm on vacation from the tablet stuff. Haven't really paid much attention to new LewaOS or Lollipop releases. I doubt if there even are any. Actually I'm thinking of getting myself a new toy, Chuwi Hi8. It has an 8" 1920x1200 screen, z3736f (2,13ghz or something) cpu....etc.....etc.....And costs only about 90 euros.

---------- Post added at 02:58 PM ---------- Previous post was at 02:54 PM ----------

Maybe your battery just got depleted. Try to charge the battery for 20-30 mins and try to turn it on again. If that doesn't help, try holding down the power button for 20-30 secs.
[Windows 8 General] EndlessRoeDeer:
Do you guys think that there will be an official Lollipop push for teclast x80h ?

Like an option to update just from stock 4.4.4 or it must be done manually even when the 5.0 will be released ?
[Windows 8 General] sbasil:
I can almost hear the crickets here...It's so quiet here. :) Anyway, we'll just have to wait and see about Teclast's update policy. IMO, clean install is always the best way to install ROMs. More than often things start going south after big updates. Installing Android on x80h takes only a few minutes so it really isn't a big deal.

edit: I noticed that the official download links don't work anymore...maybe they're cooking something new...or not :)
[Windows 8 General] taranum:
After flash bios my windows asking for activation :(.Any solution for this guys
