To sbasil 32Gb Android Instability

Interesting what you say about 32Gb Kingston Instability. I had exactly that problem on an Android phone but with Scandisk 32Gb. Posts said that the combination of after 4.1 and Scandisk 32Gb was not good for similar reasons. The posts said that prior to 4.2 the card worked OK and that 32 Gb Class 4 cards were OK with 4.2 - 4.4. Some claimed it was a timing problem - Class 10 is "Too fast". The fact that you are stable on Windows suggest that it is an OS issue rather than a hardware one - I'll see how I go on a 32Gb Samsung Pro card.
[Windows 8 General] sbasil:
Yeah, it's not a hardware issue but rather an OS related problem. Android has always been a bit nitpicky with sdcards.

Blurry display on Android

You might have noticed but the screen is not that sharp using Android like it is in Windows. The default Teclast Android install looks blurry why some other Android OS variant like LeWa OS looks sharp and clean. Does anyone know the reason? Is there some kind of kernel module that would fix this? Changing the DPI to 188 doesn't help.
[Windows 8 General] sbasil:
Could be partly because the lcd density is set to 212 in LeWa OS (vs. 160 in Teclast's stock ROM).
[Windows 8 General] Stewart Davidson:
Blurry Android

There is no difference in definition between Android and Windows on my X80h - both crisp. Have you downloaded the latest android update that installs Play Store ? If not, that might help - see my previous post on how to do that.

Bios Files FB6M

where i can download the official bios for Teclast x80h fb6m ?
[Windows 8 General] tasoskoul:
I have noticed exactly the same thing. In windows everything is clear but in android looks pretty blur. Does anybody know what can we do for this? The difference is quite obvious unfortunately...
[Windows 8 General] sbasil:
Try some different launcher. Most of them seem to be pretty poorly optimized for x80h's screen. Mi Launcher looks pretty good (adjust the font size, download a good icon theme)....That is if everything isn't blurry, including websites etc. Mine looks ok. Might not be as clear what is was with Windows but pretty damn close.
[Windows 8 General] ninezero:
Got mine too, I'm very happy with that tablet but it doesnt charge, when its turned on (anymore).

Started a thread for this problem. Some experienced similar problems?

I just tried the HDMI it on my x80hd and I couldn't get it to work. There is no output under Android or Windows. Has anyone else experienced the same?
[Windows 8 General] Braccoz:
my x80h had a faulty hdmi output. it would just not work nor detect any monitor/tv when connected to it. returned it and i'm now waiting for new models based on cherry trail
[Windows 8 General] sbasil:
Funny. I just tested Onda V820W's Android on my own x80H and it works pretty well. Can't adjust screen brightness and there is no sound, but other than that it works (I only used system.img from Onda). V820W is about the same price range, but if they got their specs right, it's got a ten point touch screen. Not bad. :)
[Windows 8 General] billflu:
Braccoz, that's interesting. I wonder how many people never get around to testing the HDMI output. I actually just tried again a few minutes ago and got it to work. I had to angle the connector a bit. It must not be soldered onto the board correctly.
[Windows 8 General] Braccoz:
mine just didn't work no matter the angle, the cable, if i pushed it in any direction or anything, just a no go.

i'm honestly doubting the build quality of teclast products... people say they're high quality but i think they just stop at the exterior because almost everybody has some kind of hardware issue with the tablet (either this one, or the x98 models)

i think i'll just be avoiding this brand for my next purchase

My tablet HDMI works. Connected to DVI monitor with speakers through adapters :D.

Install Windows Problem

Problem to install Windows

All BIOS settings are correct to allow USB boot, the BIOS detects the USB drive, the USB is correctly partitioned and formatted to boot to a UEFI BIOS. Even selecting force boot from BIOS just flashes to black for a second and then goes back to BIOS.

i have a X80h FB6M
[Windows 8 General] B^4g:
Have you on USB drive EFI /Boot folder containing bootia32.efi and bootmgr.efi file in root directory?

If no, device cannot boot without these files. Windows is 32 bit, right?
[Windows 8 General] oile:
Reflash dual boot bios from Android!
[Windows 8 General] shiggs1988:
Sorry to hear that, took delivery of my X80HD yesterday and can confirm the HDMI to be working just fine. Can only assume it's a faulty unit if it's not working under either OS?

I'm pretty impressed with this tablet at £80, but can also confirm that the display under Android looks much fuzzier than in Windows. Will tinker and report back!
[Windows 8 General] jjuniormestre:
Yes, have all files.

I broken my bios, the tablet not turn on.

I have a fb6m, the bios files from fb5m work on fb6m?
[Windows 8 General] sbasil:
Where is it available (fb5m bios)? :cyclops:
[Windows 8 General] jjuniormestre:
In this link: http://pan.baidu.com/s/1jGvcd2A

inside has a file named "bios" is a file and within cmpactado have two bios, one that supports only Windows and other dual. The bios with Name in Chinese and ends in .bin is the single boot version.

In truth should be the bios FB4M and the dual should be the FB5M, wanted to know if they could use in my FB6M because it no longer works, because that just corrupting the bios. I'll have to take the tablet in an electronic record to the bios, the problem is not work the bios that I downloaded.
[Windows 8 General] sbasil:
THANK YOU so very much! :) I just flashed my x80h's bios and IT WORKS!!! YAYYYYY!!!!!!I followed these instructions here http://xdaforums.com/showpost.php?p=59132512&postcount=342

(rooted my android, downloaded the bios from your link, then rooted my tablet and downloaded fpt-tools-package and followed B^4g's instructions.. I thought that I would never see Windows on my Teclast again, but I'm glad I was wrong. You literally saved my day! :)
[Windows 8 General] jjuniormestre:
You teclast is fb6m?
[Windows 8 General] sbasil:
No, mine is fb5m.

---------- Post added at 01:14 AM ---------- Previous post was at 12:33 AM ----------

Lets hope Android gets some sort of an update sometime soon to fix the somewhat blurry'ish screen. I would have no difficulties making my x80h a single boot (Android) tablet if it gets fixed. I had forgotten how much fun Android can be at its best! :)
[Windows 8 General] jjuniormestre:
Whats the file you has ben used? a dual bios or a single bios?
[Windows 8 General] sbasil:
I used the dualboot bios (tpad.bin) since I have fb5m.
[Windows 8 General] jjuniormestre:
Ok, thanks
[Windows 8 General] shiggs1988:
So had a few hours last night to mess around. I achieved root using the aforementioned X98 Toolkit. Cleaned up a lot of the Chinese junk that came pre-installed.

I also took this opportunity to edit the build.prop and changed my language/locale defaults but also my 'ro.sf.lcd_density=' to 189

I think this has definitely improved the clarity of the display in android but it's still not perfect. I've also noticed that the height of both the navigation bar and notification drawer are now larger and more user-friendly.

Please note that these changes only become active upon reboot.

Also tried to install Xposed which worked but resulted in a bootloop. Managed to boot android in safe mode and uninstall the framework and rebooted. Android now boots without issue - will have to read the threads more thoroughly to see what the Xposed workaround is...
[Windows 8 General] dr.diggler:
QUOTE from sbasil xposed works with the instructions provided at x98's forum (http://xdaforums.com/andr...x1536-t2913035).
[Windows 8 General] shiggs1988:
Thanks, had a brief look myself earlier and will hopefully get to try it out again this evening using this guide
[Windows 8 General] dr.diggler:
Hey.! Could you provide me a Screenshot before and after change of resolution?
[Windows 8 General] shiggs1988:
Well Xposed is installed and now working on my X80HD; GravityBox works like a charm as ever. Will try and grab some screenshots over the weekend if I get time.

On a separate note - has anyone had any luck reverting the navigation bar back to stock? I really dislike the volume buttons, and the screenshot function is a waste of time for me (with the exception of the above ;) ). Tried using a module in Xposed to change them but it resulted in the SystemUI endlessly crashing
[Windows 8 General] elastor_bastardo:
I opened my x80h again (just for fun) and i have seen that there is only a 4400mah battery inside. Not as described a 5000mah battery. this is just for information for all of you.

I´m also still looking for a solution to charge AND use OTG mode simutaneously. I got a "special cable" from gearbest but this is not working even with my note 3. Any Ideas? It´s weekend, time to do some diy things :D

is it possible to do that?

---------- Post added at 02:11 AM ---------- Previous post was at 02:10 AM ----------

mine is fb6m,thanks
[Windows 8 General] elastor_bastardo:
take a look again at this thread. few pages before there is one custom rom in an early early state. In my point of view installation will be done with factory flash tool from Post #2 but i´m not 100 percent sure.

For my USB OTG Charge problem i have found a thread in a german android forum and they are using a specific OTG Hub from banggood plugged in at tablet booting and charging and data transfer is simultaneusly possible. I still can´t post links :( but will do asap!

Edit: Bangood SKU: SKU203271 just put SKU into searchbar at Banggood and there it is!

QUOTE from android-hilfe. de from USER Michael and translated:

important:

The cable must be plugged in when booting once (eg switch position 2).

Then you can pull it off / pack / supply with or without electricity as you want.

Once you have however changed in position 1 (pure HUB mode - is required to for example to function even in the UEFI) position 2 doesn´t work anymore.

You have to do the procedure with "wired at the boot" again.

[Windows 8 General] gsneddon:
Ordered the x80h off of banggood after being impressed with the x98 air 3g. Does anyone know if the tempered glass style screen protectors are available for this model?
[Windows 8 General] elastor_bastardo:
Searched the whole internet - found nothing. If anyone is successful, share the source!
[Windows 8 General] gsneddon:
I'll do a bit of measuring once I receive the tablet to see if dimensions are the same for any other models that have glass protectors for them.
[Windows 8 General] bushako:
Closest dimension i found was the nexus 7 2013. Might not cover the entire front panel but it should cover the lcd screen area.
[Windows 8 General] sence:
Hi mate,Is there any good quality screen protectors available for this tab? Do you have any recommendations?
[Windows 8 General] shiggs1988:
Well the screen on my X80HD is plastic and soft as hell, managed to add a 5mm long scratch on the left side as I was scrolling in Windows - there must have been a tiny piece of grit. I've never scratched a device's screen so soon after receiving it (4 days!). :crying:

BUT I did manage to fish out a spare matte screen protector I had for a Nexus 7 (2012) - this covers the screen perfectly and even the cutout for the front camera lines up. There's just a narrow margin left uncovered along the bezel space.

Luckily the adhesive on the screen protector goes some way to hide the scratch and it's now barely visible. My advice is protect the screen ASAP - unfortunately I was still waiting for my tailored protector to arrive from Hong Kong.

Event 41, Kernel-Power

Does anyone noticed similar issues? Sometimes when i turn on the screen I can see my windows login screen, and need to enter PIN/password. It is not hibernated but it looks like it keep restarting itself somehow as no running apps I can see if I log in. Looks like it crashes a few times / day with the following errror message I see in the Event Viewer logs

Log Name: System

Source: Microsoft-Windows-Kernel-Power

Event ID: 41

Level: Critical

Description:

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

So basically I put the table on sleep by pressing the power button, leave it on the desk for hours then I press the power button again and I need to login again so all my open apps are closed. It seems it lost power and reboots. Battery is going to die - it is about a month old only ? :( Also I have noticed that this happens only if the tablet is hibernated/sleep mode - I couldnt' see it during realtime using the tablet.

By the way I'm using Win 8.1 (own legal version, not bing). Can't confirm the same on Android since i'm not using it that often. Ideas, advices?

i think you just can't because cerberus reads the IMEI of the phone/tablet, but x80h does not have a cellular module so there is no IMEI...

I have a bit of a usability issue. I use the HDMI out under Windows and extend the desktop to get the full 1080p. The problem is trying to move a video over to the TV with just the touchscreen. VLC lets me put more than half of the video onto the TV screen then putting it in fullscreen mode opens it on the TV. Other players don't work as well. Is the only solution to carry around a mouse?
[Windows 8 General] bushako:
Hey thanks for mentioning that nexus 7 bit, I'll probably order a glass protector from aliexpress. It still sucks to know that the actual panel is plastic.
[Windows 8 General] oswald-p:
Hi,

I am very surprised about what you say. It does not look like plastic to me...

Just a very stupid question (don't feel insulted by it): did you remove the plastic adhesive which is present on the screen when you unboxed it? Mine was so tightly fitted that I could barely see it (actually, I saw it the second day after receiving it :eek:)

Cheers

O-p
[Windows 8 General] billflu:
It looks like they just recently started making a similar case for the X80HD. I ordered one for $7 off of AliExpress today.

I searched some time ago audio booster/enhancer. I was thinking DFX Audio Enhancer is player plugin, but I was wrong. It is audio layer device emulator and works great. Trial mode show popup to buy plus version and it is limited, but useful instead other tried applications.
[Windows 8 General] shiggs1988:
Hey, no offence taken!

Thanks for the suggestion but I received the tablet with only a loosely fitted plastic which had the orange Teclast info on.

I can't see any other protector on the screen despite plucking furiously at the edges.

I have the X80HD so perhaps the quality is not as good...
[Windows 8 General] oswald-p:
Yes, the triangle with the Teclast.com logo was very easy to peel off, but the there was an other screen protector that I didn't saw at first time.

I just checked and my screen is made of glass... so there is something obviously strange with your device.

Cheers.

O-p
[Windows 8 General] shiggs1988:
But do you have the X80HD? Or the original x80?

If there's another protector, I certainly can't remove it with my fingers!
[Windows 8 General] sbasil:
Here's little something for those who own Linux and want to tinker with system.img before installing Android (remove apps, modify build.prop etc.). Just copy system.img to PLACE_SYSTEM_IMG_HERE-folder, run RUNME! as root and the rest is pretty self explanatory.

Hello. Just to let you know, my Teclast X80H didn't came with the cheap chinese memory, but I have a Toshiba eMMC!

In the box i also had a certificate of authenticity, and it came with an OTG cable and screen protector (other than the one preinstalled).

After installing Windows 8.1 PRO over the whole disk and installing the dedicated graphics drives as well (did you know that it has a Intel Graphics HD4000? The same on Sandy Bridges) the startup takes less than 10 seconds (completely powered off to start screen), and it's fast as hell!!
[Windows 8 General] sbasil:
Seems to be clearly faster than what I have. However, the SSD is not the bottleneck, the slow sdcard reader is. (<25mbs read and <15mbs write speeds with a fast sdhci sdcard).
[Windows 8 General] xxLeoxx93:
Since I had 2 x80h's, I can tell that there are at least 2 versions, one with BIWIN emmc and one with Toshiba emmc. But the screen of the biwin versions looks a bit better with brighter colours.

Besides that, I can't feel any diffrence in speed etc.

Btw: Every Atom-BaiTrail hat the Intel Graphics HD4000, so no, I'm not suprised :p

One other thing: There is a issue on some intel atom devices with a driver (can't tell which one). If you use fast startup (default on windows 8.1) or hibernation, the driver is going mad. You can see this using the task manager -> the process "system interrupts" is taking ~15% of the cpu usage all the time. Disaabling the fast startup and hibernation can fix this.

(I've only experienced this on my toshiba-emmc device.)
