Teclast X98 Air - Bios update or reset to defaults with no keyboard - Teclast X98 Air 3G

Hello,
My Teclast X98 Air (first version, no 3g) stopped charging, and while trying to fix it, I changed some USB related BIOS settings that made the USB port stop working.
I've solved the battery issue resoldering the cables, but the USB port doesn't work. At this poing I can enter the bios, but I can't make any changes as I can't connect a keyboard and the touch screen is not being recognised in the BIOS.
I can only think about re-flashing the BIOS, but I couldn't find a bios for this model anywhere. Is there anything else I can do?
Thanks!

Hi. I think the only way is to reflash bios chip with programmer (you have to desolder chip). You can ask Teclast for bios on twitter, they should provide bios for your tablet.
In my case I have fixed broken bios myself, using UEFITool (bios editing tool) by extracting options from "defaults" section. My post: forums.overclockers.ru (append /viewtopic.php?f=25&t=479847&p=14995548#p14995548 )
I tried to contact Teclast by email. No response. Then I started to dig. Later I got in touch on Twitter, they have posted bios for me.

Ok, Obrigado

Disconnecting the battery wire does not reset the BIOS settings. Is that right?

HTC Diamond USB error

Hello everyone,
I'm having a problem with my Diamond. When I attach it to a USB port nothing happens. No 'hardware found sound' or what so ever.
I tried several other pc's with no result. It does charge when it is connected and the phone asks whether it needs to be in USB mass storage mode or in Active sync mode. I havent found anyone with the same problem so I'm afraid it is a hardware failure?
I tried:
-Soft/Hard reset
-Several computers/usb ports
-Disable Advanced Network capabilities
Does anyone have some tips that I haven't tried already that could help me out?
Thanks for your time!!
Disable Advanced Network capabilities under USB->PC in your Settings, that should do it.
I tried that also. With no result yet. Any other tips maybe?
First, check your cable for any marks that resemble rabbit bite marks or alligator bite marks.
No, seriously, check the points where the cable goes into the plugs for any obvious signs of damage, then check the cable itself.
Maybe, try using a different cable, if that doesn't work your Diamond most likely has a problem. If the different cable works, your cable is a goner.
Although I think there's quite a small chance that that's it, it's worth trying, right?
Use the 6.1 version of the Windows Mobile Device Center under Vista
Thx for all the tips. I didn't manage to get it working though
When the phone is connected to the charger it asks if I want to use activesync or usb mass storage. A friend of mine has also a diamond and his doesn't ask this. My conclusion is that it is broken
Damn I got this phone as a replacement for my broken K850i from my provider...They will go crazy when they see me again
Hi,
I have the same problem.
My guess is that it all started with a non compatible charger.
When charging it asked for active sync or disk.
After that the problems started, active sync doesn't work anymore.
Sometimes it workes when advanved networking is off.
Tested on different pc's, freshly installed.
Complete factory settings, notting works.
If synchronised by bluetooth it works.
I'm affraid i have to send the phone back for repairs and trow away the bad charger.
I never used a 3rd party charger.
Is there a way to update the firmware via bluetooth?? Because i'm still using the old slow version...
Same problem here. I've used my tomtom USB car charger. Is this a guarante matter, or do i have to pay for the repair?
You may have set the default connection to other than ActiveSync when first seeing the pop-up.
Go to 'Settings' 'Connections' and select 'USB to PC'.
Ensure ActiveSync is selected.
If you want the pop-up to display when the USB is connected (its good when you want to use your internal micro-SD as a memory stick), check the box at the bottom. You can select ActiveSync, Memory or PC Modem from when it appears on connection but when you just ignore it, it will perform whatever default selection you wanted last and then dissappear.
If all else fails perform a hard reset!
I've tried /soft/hard reset. No luck..
Can this be a hardware related fault, or could a ROM flash resolve the problem?
Transfering video files via BT is a pain in the a*s...
i would try a flash before returning it. You can probably dl an official 1.93.xxx.xx from htc and try that. You don't need hard spl and all that for those ROMs.
I have the same problem:
no connection at all from the PC-side. The Diamond comes up with the ActiveSync/Discdrive question and starts charging, but nothing else.
I did use external chargers that also trigger the ActiveSync/Discdrive question.
Update:
Oops, it seems fixed after a soft reset.
Same problem, diamond would not connect to PC.
Solution: Warranty repair---> they changed the motherboard, and everythings is good. Everything was free.
Edit: But now I have a different problem. I connect diamond in to PC, everything is good, but about 30 seconds after, mobile center looses the diamond, and sync won't work. Any solutions?
I have the same problem before. My Diamond USB cannot be recognised by the PC. Took back to repair and now working. But one PC still cannot recognize the diamond. The service centre told me they have reset my unit and when came back, everything has been cleared. I suspected a full reprogram of the ROM.
I have the same problem
I cant have any connection to the PC
so, no solution but the service people
USB Connection ERROR
I have the same problem. No computer seems to be able to connect to my P3700. I tried DL new ROM but I don`t know where my device came from. On HTC site from HK, which is the only one where I found a neutral Diamond with no carrier associated like, Sprint , Telus, or the like, its says The ROM Code can only be updated on HTC Touch Diamond Hong Kong English Version Device
Does anybody have a clue how to find out where my device was originally intended to be marketed? My ROM is 1.93.456.2 WWE dated July-10-2008? Do the the numbers 456.2 mean anything?
Help is highly appreciated!!

I already did. The first few times the problem occured it worked. I have 6 different USB wires and they all cause the problem. When I hook up my HTC Touch, they all work well!?
Won't sync with PC
Hi,
I have the same thing where it won't sync with any PC and i've tried all the "other" fixes and I've sent it to the service people to have a look.
Thing is, because I thought it was an issue with the usb connector I thought I would have a poke around with it myself and i could see one of the prongs looked like it wasn't making contact. To cut a long story short whilst i was trying to fix it the plastic tab in the mini usb connector came out completely
Service people are now saying that I've abused the handset and want to charge me £70 to fix it. Now to be fair, I have made it worse, but in my defense it was only because a fault had occurred that I started to dabble.
I also reported to the service people that the led light under the "end call" button had stopped working completely. This was definiatley not due to miss use.
I'm wondering if this led is on the motherboard like the usb connector is. If so, can i be cheeky and just ask them to fix the led and not the usb? but by default because the m/b would be swapped out then the usb would be fixed anyway?
If you looked at my phone it looks well cared for (which it was!!!) and its not like I've hammered it in anyway.
Anyone have an opinion or know if the led for end call and the usb port are both on the motherboard?
Thanks

USB disk drive causes XP explorer hang

Sorry if this has been covered - I searched and googled with no success.
When I try to connect my Diamond as a USB disk drive it causes windows explorer to hang (Win XP SP2) and it only unfreezes when the USB is unplugged.
This happened with 2 different diamonds (I sent the first one back because of another problem) with both the stock Orange UK ROM and Dutty's 1.8 ROM. It seems to work fine on some other PCs. I would say it was a PC issue but it's not an isolated case - I've seen it happen with a friend's Diamond too, on his work laptop.
Edit: I should mention, it sometimes unfreezes and starts working if left connected for several minutes!
Anyone have any experience of this?
Thanks,
Dave
My XP SP2 does NOT have this problem...

Neither does mine.
Thanks for the responses guys. I didn't think it was an issue that would affect all computers, however I have personally witnessed it with 3 different Diamonds and 2 different PCs so I'm guessing somebody else must know about it.
I don't want to reinstall XP with no idea whether it will help so I guess my next step is to see if any other USB devices could be affecting it.
I think I've resolved it
I had to unplug my WD external HDD. This is a slight pain because it contains all of the media that I want to copy on to the Diamond!

Which Rom are you using?
I am not sure about that - How to check that?
Settings>> System>> About
Window Mobile 6 Professional
Original that comes with HTC Tytn II, I haven't updated the ROM.
I have downloaded this one
RUU_Kaiser_DOPODASIA_WWE_3.29.707.0_radio_sign_25.83.40.02_1.65.16.25_Ship.exe
but not able update as I am not able to connect, even I try to do using Boot from USB - Pressing Power Button and Camera Button but no luck on that also.
Please see the attached images also, picture after connecting to the USB cable, you can see Mobile is charging and in ActiveSync (Which didn't auto started, I forcible on it) shows this msg.
Now I hope it would be a better pic of the problem.
If you're still under warranty -- SEND IT IN -- just tell them you can't synch the phone anymore.
If you're warranty is expired, take a magnifying glass and look at the connector on the phone. See if any of the pins look out of place, and if so use something suitable to carefully move the pins back into position. BE CAREFUL or you'll break a pin or the connector and you'll have to go to the next step.
The next step is to send your phone to a repair shop. HTC will repair it even if its out of warranty, and they'll charge a lot for it too. PPCtechs in the US will do it for a more reasonable price.
Seems the last option is to send to the service center, as the place I am in hasn't have any service center of HTC.
One more thing I am able listen full stereo songs using the headphone - which also connects through the usb port.
No option then have to give to the service center.
Not sure of the differences (if any) between HTC TyTN II and the Tilt from a settings perspective, but I did have the similar problem with my Tilt. Under Settings\Connections there is a "USB to PC" setting. I unchecked the "Enable advanced network functionality" box and the ActiveSync now works fine.
Hope that helps.
Yeah I did that ...(enable and disable of Advance USB)... tooo
I have a GPRS connection, by which I was able to share internet of PDA with Laptop.
Now when I am trying the same, its saying check USB cable., But through Bluetooth PAN its getting connected.
A proper search whould have confirmed waht one of the replies suggested. Check your USB connector, there are several pins in it and if on that is used for data transmission is bent/broken then it would cause what you describe.
This is a thread that never should have been, consider it closed. If you need more info find one of the existing threads about broken kaiser USB port/connector.

Teclast x98 Plus 3G Windows won't start, need help with reinstall

Hi
I have big problem with my tablet. I wanted to delete the Windows.old folder and I used ccleaner. After this my tablet restarted itself and was "Resetting in progress 5%" (or something like this). It stuck at this screen about 6 hours so I turned it off. Now when I choose windows in dual boot option, there is a teclast logo and than black screen. In about minut it restarts. I tried to reinstall Windows, but I can't boot from USB. I tried with Windows 10 from Microsoft site and also win10 for teclast from this forum. I think the biggest problem is that I don't have an usb-keybard. Could anyone help me?
What I have:
-lot's of usb sticks
-micro usb keyboard
-otg cable
-hub usb (normal size usb)
-usb mouse
PS Android works normal

Teclast X98 Plus (A6C7) OTG not working

Hi everyone,
I've just bought a brand new X98 Plus (A6C7), and installed mirek's rom V3 without repartitioning.
However, somehow I've lost OTG....can't specify how or when (just know that when i got the tablet it worked).
Whenever i connect the OTG cable it does not power-up anything. I've tried mouse, flash drive, keyboard, both on Windows and Android...and the neither of them powered up (mouse didn't even light the laser).
Just to clear things, I've tested the keyboard, mouse and flash with a PC, all OK. Tested the OTG cable with the same mouse on a different android and it worked just fine.
I can charge the device, connect it to laptop (after noticing this, I was still able to a fresh install of android just in case it was something to do with the flash)...so it does not look like the connector is broken.
Anyone can give me a help with this?
Thanks
