bluetooth + wifi = complete disaster

ive done a fair bit of testing now it looks like, for me at least, that bluetooth and wifi fail to function properly if they are both on at the same and in use.

i connect bluetooth to my bluetooth speaker. internet stops working in android.

with wifi on i cannot pair my bluetooth speaker. the second i turn off wifi *ALL* the nearby bluetooth appear instantly. its a very obvious fault on my tablet.

can anyone else confirm the same issue?

Sold my tablet for same price and got ASUS T100 64GB for $30 more.. with keyboard. (Not bad deal at all and loos new.. and sleeps like beauty. This teclast screen is good(+ dual boot) and everything else sucks big time. As I have other Android tablets lying around.. Just went for Windows. I went through every forum to fix Sleep problem with there is none. wifi also sucked on my tablet. NOT worth it in my opinion.
[Teclast X98 Air 3G] 25gee:
Hi, sorry about the late response, had a hell of a lot going on lately.....

As for accessing the device for the file-names I'm not sure what you are referring to? the files are on your PC the flash.xml file and other related files should be browsed to within the flash utility, you should put the device into DnX mode, setup the flash utility and point to the flash.xml file using the browse option in this, this is where I mentioned to check the path to the files to see if any of the folders/filenames have odd characters in them (any unicode or chinese characters in the path such as "c:\users\mynamehere\downloads\roms\㣩議-My Rom\flash.xml" will not work because of the characters) the fact that it gets to 10% suggests that the device is seen by the utility which is a good start, I had this issue for days until I found a funny character in one of the folder names.
[Teclast X98 Air 3G] swidmier:
So, the files with the funny characters are on the computer I am using to flash the tablet and not on the tablet itself? Those I can access. Though I did try changing them but may not have gotten everything.
[Teclast X98 Air 3G] mullepol:
I just flashed mirek 190 3.1 on my HG9M (64G dual boot) successfully. It took a third computer to do it. Failed on Win 8.1 Failed on Win 7. Only succeeded on another Win 7 where I had never installed adb or anything like that before. Did take 3 tries. On both previous computers adb just refused to notice the device.

Anyway. I'm having problems with the touchscreen being wrong. It seems to scaled differently to the screen itself. When I drag down the notification bar it stops roughly half as low as my finger. And clicking on notifications activates roughly half as far down. Anyone seen anything similar before?
[Teclast X98 Air 3G] 25gee:
The files you are flashing to the device reside on the computer being used to flash the tablet, if the path to these files contains any funny characters anywhere then the process may fail, this was noted early on in the Air II 3G thread.

It may not be the issue you are having at all, but just check that the names of any folders in the path do not contain any funny characters as this will stop it getting past 10% as happened on both of my tablets.
[Teclast X98 Air 3G] swidmier:
I am floored! It actually worked! I just downloaded everything from http://techtablets.com/teclast-x98-air-3g/downloads/, replaced config file and partition tables, and it flashed. Didn't find any files with funny characters so I didn't have much hope but it actually worked! I also didn't do the setup...guess the defaults in the flash tool were correct for my tablet. Anyway, I have successfully flashed the tablet and am now re installing the dual boot function. Thanks! :highfive:
[Teclast X98 Air 3G] swidmier:
I successfully loaded android, the dual boot bios, and then my backed up copy of windows. My issue now is i do not have the code to verify windows. i never got it from banggood. without it i cannot install the dual boot bios in windows so am currently stuck. I emailed Banggood but who knows when i will hear back.

iGO Primo Does Not Detect GPS

Hi billquinn1,

Thanks. But I'll have to disagree since Google Maps works just fine on my HG5N. And the tech spec also stated that this HG5N (X98 Air Android) has GPS facility.

Did you experience otherwise with Google Maps?

Regards.

how to flash W8 Bios only from dualboot bios

Hi everyone,

I have a x98 air ii HG7N with dual bios (only W8 installed) and a lot of battery drain with sleep mode. I want to try flashing a W8 only bios to - I hope - solve this issue. Can someone explain me how to do that?

thanks for replying an d have a good day!
[Teclast X98 Air 3G] dagrim1:
K, managed to download the files... Will give it a go tonight (at work now).
[Teclast X98 Air 3G] dennemann:
Hey guys,

I have teclast HG8N, is there anyone else experiencing charging problems? I charged for hours and only got 20% charge..
[Teclast X98 Air 3G] MrRimmer:
Are you using the original charger and cable? It's possible it was only charging at 0.5A rather than 2.1A.
[Teclast X98 Air 3G] dennemann:
Nope. Was using a 2A charger from Samsumg. :/
[Teclast X98 Air 3G] dagrim1:
Ok managed to install it, for some reason I had to change the .xml file used for flashing and use the droidboot.img version from the official hg8n rom (I have the hg8n model).

About the xml file, I changed the lines reading "fastboot format" to "fastboot erase" and comment out the "formatting logs" part.

And as mentioned, I also replaced the droidboot.img with the hg8n version... (Otherwise I got an error when flashing. Something with not being able to find target partition or something?).

I used the non_partition version, as I wanted to keep my windows/android dual boot.

First impressions, feels smooth. Antutu scores about 34k, just a little bit higher then KK rom and also a bit higher then another LP version I flashed before (was for the x98 air 3g, exact same build date and all btw) but it just feels way more fluent. Not sure if that willl stay the case now that I restored my apps, but I think so.

Temp seems higher at first, not sure if it will settle down more... Something to keep an eye on.

Something very specific, the foxsports app used to crash in the lollipop versions of this rom (temp increased until it reached 64+ degrees after which the video stopped). This seems to be fixed in 5.0! Temp remains constant and no crashing/freezing. ALl in all pretty happy with this version :)
[Teclast X98 Air 3G] edmaronline:
My friend, do you mind to put here to download the droidboot.img? I have the same model and, until now I don't have any problem with my tablet. I have the dual boot version. I flashed mirek rom. Do you think this android lollipop is now better than mirek rom? Because I read that this lollipop version is the teclast version with a lot of bloatware. Do you have the link to the rom you used?
[Teclast X98 Air 3G] deepmenace:
Is there an easy way to increase the android partition...make the windows one smaller?

Or do I need to fully remove windows and go 100% android...

I like windows but the battery drain issue is too bad.
[Teclast X98 Air 3G] dagrim1:
Here you go. The zip file contains the droidboot.img and xml file I used... The document is a google-translated version of the chinese page :)

Btw, I notice some issues with cpu-scaling. Sometimes it seems stuck at minimum cpu? Antutu then gives a score of 14k (same as when I lock cpu at min, 476mhz, with setcpu, normally I'd expect around 34k... same as when cpuu is locked at max, 2176mhz). Still checking into that...

Other times it seems to work well.
[Teclast X98 Air 3G] stevenplanet:
Hello, so I just got my X98 Air II a few weeks ago. I have a couple of questions.

1)Recently I had a battery issue so I tried to fix my tablet by flashing a BIOS image from techtablets but I think I may have flashed the wrong one because now I can't boot into the android partition anymore, it hangs when I select Android in the bios menu, and two it now says that my Windows installation is unregistered and my key was blocked, so in my desktop it says Windows Build blah at the desktop. Not a big problem but it annoys me once in a while when it asks for me to register.

2) The battery is really weird. If I put it to sleep on Windows it drains within an hour or two.

3) Sometimes I can't power the tablet on. I don't know why I'll be using it fine for like 30 min and then I try turning it off. Then 5 min later I go to turn it back on again and its unresponsive. If I wait like thirty minutes or something later then it works fine lol. I feel if I got the right BIOS back itll be fine.

4) How do I know what model I have? I bought the dual boot version with android and windows and its the Air II 32 GB. Is it HG6G or whatever? I see that a lot but I don't know what model I have.

5) Can anyone give me original latest dual boot image? :D

6) Thanks for reading all the questions :)

WARNING: Do NOT flash the HG9M bios on a HG8N version tablet...

THougth it was safe to flash the HG9M bios file, but apparently not. My tablet doesn't turn on anymore now. Not even a splash-screen or bios screen. Have to see if I can and want to fix it (have to order some things from ebay to be able to reflash the chip). Ugh, sucky.

If anyone has the HG8N bios, could you please upload it? Cheers.

*Edit* made a typo, flashed the hg9m bios on my hg8n tablet... not hg8m on hg9n.
[Teclast X98 Air 3G] Leader2light:
RIP, thanks for this info though. I have the HG9M version.

We really need a table breaking down all the version and differences.
[Teclast X98 Air 3G] edmaronline:
Because of this I am afraid to flash my tablet again. I have the HG8N model and I flashed the mirek rom for a different model. The tablet, until now is perfect. I am afraid to flash Lollipop and brick my tablet.
[Teclast X98 Air 3G] dagrim1:
Well, as long as you're not repartitioning and not flashing bios files you *SHOULD* be fine... I flashed all kind of android systems and boot images on my x98 (also the ONda v9 and Cube i6 versions). Worst case is it would stuck in a bootloop but as long as you can enter the fastboot/dxn mode you can reflash.

But now it doesn't start at all anymore and that is more of an issue ;) Luckily I hadn't sold my MiPad yet, but still. Gonna order some tools which should make me able to revive it again but I'm gonna have to have some patience I'm afraid. Sucks though as I was quite fond of the Lollipop rom :/

Reason why I wanted to flash the bios btw is that I read it fixed the sleep/battery drain issues under windows 8.1 (Where connected standby drains the battery)
[Teclast X98 Air 3G] stevenplanet:
did that fix it? i have the same exact problem haha. if yes can you provide the bios you used that fixed it? thanks!!!
[Teclast X98 Air 3G] dagrim1:
As I understand the HG9M is the 64GB dual boot version of the air II... Correct?

May I ask where you bought it, and what emmc drive is used for it? As I understand there are a number of brands and BWIN is one of them but unfortunately is the slower one... (My HG8N had a BWIN flash drive). I think you should be able to find that information in windows (device manager) at the drives section or something?

Reading around the various M and N models are dual boot and android only (although quite a few of the android only have been made dual boot) and I guess the different versions HG5X - HG9X are small changes in hardware (emmc drive has changed, camera modules, etc). But yeah, it is indeeed pretty unclear what is what.
[Teclast X98 Air 3G] xanderluck:
Hi guys,

i have hg9n version, anyone can help me to find bios version for android, windows or dual ?

I have flash and now no way to have touch calibrated even in bios, i have tried to reinstal official android but nothing.

Thanks
[Teclast X98 Air 3G] dagrim1:
Ehm, in my previous post you could read that I bricked my tablet by flashing the bios... So no more battery drain, then again... Alsno no more tablet ;)

Ordered the tools to revive it, should come in in 2-4 weeks. Wonder if I can fix it in the end.
[Teclast X98 Air 3G] stevenplanet:
Which tablet do you have? There are too many pages to read all the posts :P. I have the X98 Air II Dual BIOS Android and Windows. I flashed the wrong BIOS and the tablet wouldnt turn on, however at times it would turn on, but with random spamming of the power button. Try pressing it randomly, sometimes with different durations. Eventually it will turn on. It helps if you keep it charged for at least an hour before you try spamming the power button haha. Got it on and reflashed with original BIOS. Now its alright :) Just the battery drain is a little bit harsh in Windows.

[Teclast X98 Air 3G] Silver-B:
I've got the HG9N (android only version). I've flashed it with nearly all the bios's posted within this thread however the touch screen was inverted even in the bios!

To fix this issue I've downloaded X98_Air_II_Dual_BIOS (HG9M), afterwards I installed X98 Air (HG9M) Android 5.0.

This fixed the inverted touch screen, once completed I installed Windows and it's working fine.

I'm currently trying to re-partition Android as it's taking 20GB on install.

I see 64gb dual boot air II versions on banggood and alixpress for example. Thinking about buying a 64GB version anyway wrt space in case of dual boot...

I bought it directly from Teclast on tmall since I live in China, so I don't think that will be very helpful for you.
[Teclast X98 Air 3G] stevenplanet:
I have an Air II 32 GB Dual boot Android + Windows I bought about a month ago. How do I know if it is HG9M? How do I tell model number? Thank you!
[Teclast X98 Air 3G] Silver-B:
Look at the back of your tablet, it should tell you the serial number & Id in very small letters.

The id is the model number.
[Teclast X98 Air 3G] dagrim1:
I have the HG8N, guess somebody changed it to dual boot as that is how I received it.

But thanks for the tip, will give a few more tries reviving it though I have small hope hehe... Ah well, matter of patience (and part of the risk) I guess ;)

Haha, fair enough ;) Thanks though!

alixpress is where I bought it. About 200$. Works great, but I flashed an android rom and now my windows boot icon is gone. Any idea how to fix this?

---------- Post added at 01:57 PM ---------- Previous post was at 01:50 PM ----------

Can someone list the Android roms that work with HG9M or Air II in general?

Because I have flashed 3 or 4 roms and all of them have touch screen issues. Can't even unlock them in most cases.

Also after the last andriod rom I flashed, my windows icon is gone on the dual boot screen. So now I can only boot into an android rom that does not even work due to touch screen being way off.

PLEASE HELP.

These are the roms I flashed and none worked with HG9M. So I guess the Air II and 3G version don't work similar at all? Also after I flashed the jcespi2005 LIte ROM my windows dual boot icon is gone. I didn't do a total flash or anything, so windows should not be wiped out right? How can I test this?

[Teclast X98 Air 3G] Gloomba:
Have you tested the speed on yours? I have the same model and my drive speeds are just plain awful. Worse than the bwinn speeds I had seen.
[Teclast X98 Air 3G] Leader2light:
No I have not yet. My windows boot option is gone, so I need to fix that or reinstall windows. Have not noticed any slow issues though, boots fast and whatnot.

U flash any custom roms yet? What works?
[Teclast X98 Air 3G] intruduh:
I've reached the same impasse as you - the roms I've tried are unusable. Windows is still fine and I can still dual boot.

I've also tried getting the HG9M 4.4 stock rom from vmall but the rar keeps on failing. Is there a mega download for this?

So I tried the HG9M 5.0 android (I dont really want that tbh) but the flash isn't getting past the 12% droidboot problem... I think this may be because I'm using Win 8.1 64 so I'll try a Win 7 32 when I get a chance. What VID/PID are you using - it seems the teclast forums suggest different ones to techtablets...

Tried keeping the volume up button pressed when starting (power and volume up pressed at the same time)? When you disable the dual boot menu (checkmark in that screen) this will trigger it.

USe the archive I uploaded earlier this thread. The trick is to use the droidboot from your own version (I have the HG8N) and adjust the x_nopartition.xml a bit (the newer uses 'format' commands, these need to be changed to 'erase' I believe... and some part needs to be commented out). Check one of my earlier posts... I posted my droidboot.img and modified xml file there.
[Teclast X98 Air 3G] Leader2light:
I see the dual boot menu just fine. The issues is andriod icon is there on the left, but windows icon on right is just gone. What causes this? Does that mean my windows install got wiped when I flashed a android rom?

I am using the techtablets values. Flashed 3 roms just fine this way, but the touch does not work as you know. I will try and flash android 5 tonight. Can you link me to the HG9M android 5 version.
[Teclast X98 Air 3G] intruduh:
A few comments above - the baidu URL

---------- Post added at 11:36 PM ---------- Previous post was at 11:22 PM ----------

Yes, you're right about the format... what is processing the 'erase' and 'format' commands, because it's obviously assuming that that has been upgraded...

I may have the droidboot from the stock 4.4 HG9M rom (the system.img is corrupt and I'm not entirely sure if anything else is), are you saying put that into the HG9M 5.0 folder and compare the nopart.tbl? What about putting the 5.0 system.img in the 4.4 folder and flashing the nopart.tbl from that?

If I could get the HG9M 4.4 system.img and see a working android I'd be more confident in experimenting with newer roms.
[Teclast X98 Air 3G] Gloomba:
I haven't done any custom roms yet because I don't want to mess anything up until I am sure of what will work correctly. Still trying to read up on what should work. I wouldn't mind trying another rom though. The original one is periodically freezing and rebooting.
[Teclast X98 Air 3G] Leader2light:
Cant get mine past the droidboot either. Tried many different ways.

---------- Post added at 11:59 PM ---------- Previous post was at 11:56 PM ----------

Mine wont flash even with this. HG9M and dual boot bios. strange right?
[Teclast X98 Air 3G] dagrim1:
Oh! Hmmm, if you used an android only version and chose repartitioning I guess that might have happened...

Ehm, what I'M saying is that I have to use my own model's version droidboot.img (I have the HG8N model) in order to succesfully flash other roms. With other droidboot.img's I either get in recovery with an invalid media error or something else goes wrong. I simply copy my versions droidboot.img over the one in the 'other rom'. In the past I did the same for the efilinux-userdebug.efi file, but I thought that's not necessary but you might give it a try anyway. Been messing around so much now I kinda lost track ;)

If you already have the HG9M model there shouldn't be any need to change anything? I didn't do anything with nopart.tbl... When choosing the flash_nopartition.xml it should leave the entire partitioning alone... afaik. (I have actually not seen a nopart.tbl file so far).

You can get the 4.4.4 HG9M rom here, but it's incredibly slow... Downloading it anyway, just in case ;) : http://dl.vmall.com/c0ox7paiav

Other roms/files can be retrieved through this page, enter the model (HG9M for example) to get to the corresponding files: http://www.teclast.com/tools/pad/putcode.html

I haven't suffered too much from inverted or non-working touch screens. Only when flashing Cube/ONda roms.... The HG9M android 5 version worked fine on my HG8N model. You might also want to experiment with the boot.img but I believe I also flashed the boot.img with the 5.0 version without issues. Only the bios file screwed my tablet up...

What model do you have? The droidboot.img I posted was the HG8N version... I think you need the one for your model (again, not sure... just saying what seemed to work for me) and depending on versions the flash_xxx.xml has to be changed a bit.

That was my problem - and I tried again with chrome but the vmall link stops at 154M with chrome every time, and the rar fails to unpack system.img if I use FF... but I did try IE this morning and it worked fine. Flashed it and I've got that awful teclast launcher with a working touchscreen so I consider a successful download.

Yeh, sorry, just getting confused... I meant xml.

What I did find out is the PID/VID must have 09EF to work (android PID) - in my Win 8.1 64b I don't get the device drivers I've read about so I didn't have a way of checking, but 0FFF fails and 09EF works so I will try a custom rom this week, possibly the 5.0 if it can be rooted.

I have the HG9M model. I tried flashing the 5.0 rom without modifying it. Still failed at 10 percent. Will try the 4.4.4 rom now. Right now I basically have a none working tablet cuz my windows is gone and android version I currently have touch screen is flipped.

I have the HG9M as well.. the vmall 4.4 rom worked a treat but the 5.0 rom wouldn't flash even after changing the xml to 'erase' and putting the 4.4 droidboot.img in the folder.

About the only problem I have is the /data partition is 16G instead of 32 (or 27 or whatever it was) and I've been trying to figure out why and whether I can just resize the data partition but I can't see the unallocated space after the partition... a bit of a mystery how the partition sizes were changed and where the space has gone.
