Ummhhh...Unless you made a backup of your old bios OR Windows product key, there's not much you can do. Get a valid product key from somewhere (for Windows 8/8.1) or contact Teclast or the store you bought your tablet from and ask if they could spare you one (which I doubt they won't). However, IF you made a backup of your bios like you should have, it's fairly easy to get the product key from the bin file (just upload it somewhere and I'll get it for you).

Which version of Android did you try to install? Lollipop? If so, you need to replace the droidboot.img with droidboot.img that comes with 4.4.4. At least for me the one that came with LP didn't work.

teclast problem

Hello, new one here.I'm having an issue with my teclast x80h.The problem is , when it is charging while the tablet is turned off, sometimes it gets heated up a lot so as result it won't be turning up.Does anyone has a clue what the problem might be?
[Windows 8 General] sbasil:
First, try charging it with a different charger and see if it still heats up. I threw the original charger away without even using it. The quality was THAT bad (I would probably have ended up electrocuting myself at some point with it).
[Windows 8 General] prat91:
i have to mention that this only happens when the tablet is getting charged while being turned off!
[Windows 8 General] sbasil:
Ok, sounds weird. But still, try if it overheats with a different charger (when the tablet is turned off).

best rom

Hello everyone.

I have the tablet Teclast X80h ( FB6M model )

IFWI Version : 5.6.5

Build number : v1_00_20150207

But this goes hand in reboot some times when I'm on android OS .

It has been a long time off without the turn it on. I was thinking to send the guarantee , when I try to connect and work again.

The problem is the ROM ?

What is the most stable ROM for this tablet?

[Windows 8 General] dr.diggler:
i can´t find the downloadarea at teclast. they redesigned the website - no idea where to look. Also i will setup my x80h with 3.5GB Android Partition today and would like to give a new ROM a chance.

First I will flash android with flash.xml, there i will exchange the regular partition.tbl. with the 3.5GB one. This will format Windows partition too. Then i will start with windows installation. Does windows install script from teclast image sees the additional free space left from smaller android partition? I´m asking because the original image has it´s own partition script.
[Windows 8 General] elgera:
my x80HD comes only with android.

could someone explain how to install Windows?

What is the advantage to flash the BIOS?
[Windows 8 General] dr.diggler:
top secret ;)
[Windows 8 General] sbasil:
If there's nothing wrong with your tablet, there's no reason to flash the bios. In other words, you gain nothing. If you have the older FB4M single boot model, you might be able to convert it into a dualboot model through a bios update.

Or in some cases, if you've lost the dual boot menu and can't install Windows, flashing the bios might bring you the dual boot menu back.
[Windows 8 General] aerc:
My tablet as thefersion FB6M, what is the best ROM for it?
[Windows 8 General] dr.diggler:
In my point of view I would wait until a final 5.x lollipop is available. And also I would wait for a newer Lewa OS or a newer miui rom. But if you don't want to wait: lewa (4.4) and lollipop 5 beta are already very good!
[Windows 8 General] aerc:
thanks [MENTION=4405979]dr.diggler[/MENTION]

I have both systems (win+Android).

What system do you have?
[Windows 8 General] EndlessRoeDeer:
Hi, did anybody tried to upgrade windows 8 to windows 10 already ?

Is there a chance that this auto update will erase the Android partition or it will only affect the windows side :) ?
[Windows 8 General] jockyw2001:
I updated my dual-boot Voyo A1 Mini to the latest Windows 10 preview (build 10162). After running the installer you can delete the partitions used by Win8.1 and create a single new partition of, in my case, around 23 GB. If I recall correctly that is partition 17. Windows 10 installed flawlessly, you just need to install latest drivers (around 17 of them). I am very happy with it, it runs smooth as butter. Since the Voyo A1 Mini is nearly the same as the Teclast X80h, it will also work fine on the X80h.
[Windows 8 General] dr.diggler:
The same. Only difference is that I made a complete new setup of both according to guide on page 1. I exchanged the partition.tbl for 3.5gb android partition to have ~4gb more diskspace on windows. Android 5 beta running. No errors... but remind that lewa doesn't support ntfs on external sd. That's why I have chosen lollipop. But user interface of lewa is very nice!
[Windows 8 General] aerc:
Do you recomend upgrade de android system to lolipop?

It is easy to install ?
[Windows 8 General] dr.diggler:
It is more beautiful than 4.4 but still beta. A pro is that it is prerooted. I deleted the Chinese super su and installed the english version. This can be done with root uninstaller from playstore. You have to decide! In my point of view the stock rom is full of waste apps. Lollipop is a clean and stable rom. Installation is very easy but you have to follow strictly the guide especially choose "flash_nopartition" in flash tool or use sbasils flash tool to be sure to not destroy your current windows installation.

One important thing: in my case it's possible to go back to stock but FOR ME it's impossible to install update 1.04 from Teclast. I always get error message...
[Windows 8 General] aerc:
thanks.

do you know when lolipop will be realised for x80h? (non beta)
[Windows 8 General] EndlessRoeDeer:
Many thanks for your response ! :)

I am currently considering if I want to do that. I got the tablet for around two weeks and I am all the time in Android. Wondering If I want this to be still dual boot or better install Android Lollipop from scratch with 32 gb for it :)

What about the defauld os switcher on the start. It is working as before no problems ?
[Windows 8 General] jockyw2001:
My Voyo originally came with Windows only and it simply wasn't fun trying to do something productive with it. Then I turned it in a dual-boot system and soon enough, like you, I considered to turn it into an Android-only tablet. Now that I have worked with Windows 10 in the past 2 weeks, I am considering to again turn it into a Windows-only tablet. I will probably go for a compromise solution, where I will move the system and data partitions to a 128GB sd card. That way I will have around 20GB free space on the internal emmc drive. A fresh install of Windows 10 consumes about 8 GB. I will probably do that after the final release of Windows 10 is out.
[Windows 8 General] dr.diggler:
No idea.. maybe never ;) chinese support is always tricky..
[Windows 8 General] EndlessRoeDeer:
I am curious about the performance of system running from sd card. If you don't buy an expensive one I would say it would be very laggy.
[Windows 8 General] jockyw2001:
I was referring to Android, and want to move /system and /data to sd. I don't think it will become laggy. If it does, I'd move /system back to emmc.

[Windows 8 General] devinpatterson:
I think the combination of native android/win 8.1 dual boot and price, make the X80h a very attractive tablet. I'm considering purchasing one and I was hoping a X80h owner might be able to give me a bit of insight into the tablet.

However I'v been spoiled by wireless charging, and have adapted my hp stream 7 (win 8.1, 7" tablet) to work with it. I can do the same with the X80h if it doesn't require the usb sense line or the data lines to be tied together (a lot, maybe most tablets do require this for charging).

I was wondering what amp (2?) is on the X80h's charger?

Would it be possible for you to do a little test for me? Could someone note the amount of charge the battery displays then turn off the tablet. I'd just like to use a standard micro-usb cable (I'm assuming the X80h uses a micro-usb port for charging?) and a standard charger (or even a usb port on your pc) and connect it for an hour or two (while the tablet is off) to see if the charge increases.

If it does increase, it's likely the X80h can be hacked to charge wirelessly, with a typical Qi mobile phone charging tag/film....since it's only using the + & - without any additional input from the usb sense line. The HP stream 7 doesn't show as actively charging when I charge it wirelessly, however it does charge about 15% an hour with a generic 500mAh charging tag. I hope to try a 1000mAh tag/film soon, and bump up the speed. Although one advantage the stream 7 has over this tablet (for wireless charging) is it's back is removable, making placing the wireless charging tag/film very easy.

Thanks in advance, if anyone is able to help.

Hello,

I have FB4M (only with windows) and tried to flash updated bios (05.11) but it gives me error with the tool, then i make mistake to use flash tool from dual boot bios with the same file. All flash ok, but version in bios screen wasn`t changed. So second mistake use option save and reset. Then screen only light up, but no bios (post) screen or anything. I think first maybe IGP is disabled, but i read here: ondaforum.com/topic/530-onda-official-win-81-drivers-bios/

that the bios update can cause no tablet screen.

When starting tablet screen light up (in black) but it runs windows. I understand this by connecting usb flash drive (with usb hub with blue light) and hearing windows sounds. So i deceided to try "blind" firmware update using batch file converted to exe with administrator manifest:

fptw.exe -F tpad.bin >> log.txt

At the end i use 1by1 mp3 player to start mp3 as finishing flashing process :D

Here is log.txt:

This "Flash Descriptor: Invalid" blocks me to dump backup, flash bios or erase chip. Bios chip is 1.8V rated so i`m searching for proper SPI programmer. I think maybe we can use dual boot bios because is 8MB. Or someone make backup.

Seems to have fixed the issue. Honestly this tab was my only Android device being a blackberry user for some time. Now I just got a Moto x with tons of support and this tablet is now a go to when my phones on charge lol.

[Windows 8 General] sbasil:
I'm sure that Teclast would have used fb6m's bios for fb6m or vice versa if it would work better. So no, don't flash the wrong firmware (bios) on your tablet (I know at least one case where someone flashed f6bm's bios on fb5m which killed the dualboot). You could try re-flashing the correct bios and see if it helps. Just make a backup of your current bios and Windows product key before anything else.
