Will lollipop work with HG9M or Air II in general?

All andriod roms tested on my HG9M so far boot up and work but touch screen wont work / area is not set right. Can't even unlock most of them due to this.

Running out of ideas....

Hi,

I've read the thread and watched hendricksons video but for some reason I can't flash to android. I have a H6GN which came as android but I have the 7% battery issue, I've managed to flash the dual bios and install windows. Now I'm trying to flash back to android but I get stuck @ 5% on IMT. I've checked the settings and custom configure etc.

I've attached a screenshot of my of screen to see if anyone can see anything obvious.

Thanks

John

Please check

1. Check if Your tablet is in DnX mode. If no , press and hold power + vol up + vol down for 20 min

2. If 1 is yes, PC does not recognize your tablet. Open control panel -> device manager. Check of there are an ADB android device with yellow triangle symbol. Right click on the ADB device and click update driver. Select to choose driver manually. Select choose device from a list. Select Android -> ADB android Composite. Then try to flash again

It's likely that you will see same issue when the progress bar is at 12-17% again, if you do just perform the 2 Step again

Are you trying to flash lollipop? If yes, your config is correct. If no, I think the 0FFF needs to change to 09EF if I remember correctly

Guidance

Hi all,

I am struggling to sort through all of the information here and find what is specific to my needs. I am on a 64GB Teclast X98 Air 3G C8J6 with firmware version 1.07 (Build date/time 01/16/2015 12:16:21)

I would like to primarily use this device with windows. I would like to completely remove android.

A lot of posts/videos mention a dualboot firmware. I feel I already have this as I can currently boot to either android or windows so it would seem my bios is okay as it is.

There has also been mention of battery drain. I don't know if I have battery drain because I have never known anything other than the battery life I have now. I haven't played with the device enough to really comment. Is firmware 1.07 okay or bad in this respect?

The dualboot menu... Is this part of the firmware or is it something that could be lost by deleting the incorrect partitions?

In my position should I:

(A.) create a windows boot usb

(B.) delete all partitions and allow windows setup to create the partitions it requires

(C.) Install windows

(D.) Reboot and in the dualboot menu set it to always boot to windows

?

Will the above get me where I want to be?

Can I visualise my tablets partition tablet as the same as a laptop in architecture or is it a completely different beast that someone has somehow managed to get windows running on? Are some form of android partition always required to exist but can be left empty or can all shreds of android be removed?

I'm hoping that if you can answer the above questions that your answers will be useful for more people than just me because I did a lot of searching before I asked and couldn't find what I was looking for. There have been many changes since this thread started and the newer models like the 64GB C8J6 aren't covered on the front page.

Thank you for your time.
[Teclast X98 Air 3G] colo4you:
Try to leave your tablet in windows for a 3 to 4 hours if you have not applied any fix, you batt should drop 12-16%. Avg. 3% per hour in sleep mode. This is the issue. The one without issue will drop less than 0.5% per hour in sleep mode.

For how to remove android, I suggest you follow the method in the first page. The method is compatible with C8J6.
[Teclast X98 Air 3G] Wallace4793:
Hi,

Yes the device is in Dnx mode and yes the device is listed in windows as 'android phone" or something. Apologies I originally had 09EF... Same problem. I'm struggling to understand how no one else is having the issue :(

hey

I can't get advanced bios options to chnage to turbo? Do ineed a different bios, I have origina HG8N dual boot.

Or does system use boost when required anyway?

---------- Post added at 11:03 AM ---------- Previous post was at 10:49 AM ----------

ok, found the answer to the first part, new bios has no options, but anyone can answer the second part?
[Teclast X98 Air 3G] blasti99:
I investigated on the bios and found that the flash dump contains more than just the "BIOS". The actual BIOS is only 5 MB as you can see in the attached screenshot.

however, there are also some smaller parts within the actual BIOS that can contain differences, like the Windows KEY.

Appart from those minor differences, the actual BIOS of the posted flash-dump is exactly the same as in the dump that I created from my C8J6 flash.

I guess we can only find out by try and error.... so anyone having a SPI flasher could try to flash different bios files (full image and just the 5MB bios) to find out what actually bricks the devices.
[Teclast X98 Air 3G] colo4you:
Thank you for your great idea. I tried to decompose the BIOS and compared each part with the posted dump.

The result was that

--------------------

The descriptor regions were identical

The ME/TXE regions were quite different even if addresses, size and version of the TXE were the same.

The BIOS regions were also quite different. (not just the Windows key area) However, the date and version of BIOS was identical.

I upload both BIOS here so that we can help investigate. https://db.tt/FCQrAluZ

PS. I already removed Windows key from both BIOS images for security reason. However, I have not patched both BIOS images to support all models. SO DO NOT FLASH THEM ON ANY MACHINE. IT WILL BRICK THE TABLET.
[Teclast X98 Air 3G] colo4you:
Are you sure that the device listed in device manager does not have the yellow triangle symbol on it? According to your screenshot, the issue occurs because of PC does not recognize your tablet (DnX mode). can you send me the screenshot of your device manager while your tablet (DnX mode) is connected via USB?

I already flashed the lollipop for C5J6. I found 2 problems 1. rear camera auto focus does not work 2. GPS does not work. Do you have the same issues?

Moreover, I try to uninstall some "system" Chinese apps (ex. baidu, etc.) by using Link2SD in root mode. It crashed my tablet and I have to reinstall lollipop again. Have you done that with success?

problem with teclast

Hello,

I have 2 problems with my tablet. First, when i watch stream (etc. twitch.tv) its working perfectly for few minutes, but after that... it's stuck. The same problem at windows and android, refreshing website don't help I have to close browser. My second problem is game called hearthstone. It's not working smooth, but it should work that. I downloaded software from 1 page, that should make it working better, but nah.

Any ideas...? Anyone? :(

If u want WATCH twich without this problem, download APP Gamestreams in MARKET of windows, i have ur same problem.
[Teclast X98 Air 3G] nrdmtt:
+1 I had a similar problem. Try by installing this driver.

Hi,

the problems that I have found till now are:

WIN: When I shut down from windows, the tablet make some difficult to switch on again. I have to press the power button a lot of times and wait 2/3 min. (to be investigated, maybe the tablet is not really switched off even though the screen in off)

WIN: Battery is reported as 14.400mwh, but no battery drain.

LOLLIPOP: Play store bug, fixed by uninstalling the old play store and play services and installing the new one

LOLLIPOP: The system after 10 min of usage start to become laggy (the UI is still responsive but, for example, chrome scrolling become laggy)

LOLLIPOP: Rear camera autofocus broken

LOLLIPOP: No GPS fix.

I had also the same problem with the chines app. The first time, I have uninstalled the one called "Game Center". Had to reinstall Android. Just freeze them.

I will upload a screenshot with the apps that I have disabled. I have also kept, tUI, Game Center and TeclastAutoUpdate.

Lol, join the club... Exactly the same here, flashed the HG9M bios on my HG8N device. Seemed to work fine, until restart... Also ordered the tools, also have to wait a long time hehe.

Ah well, all in the game. Just hope it's possible to revive it in the future (mainly a matter of finding a bios that actually works it seems) ;)

BIOS 2.02 Battery Drain in Windows

The fisrt time i flashed the bios 2.02 directly from X98 windows it bricked. I purchased the programmer and flashed the 2.02 with the programmer and it worked fine :)

About the battery drain issue in Windows i got exactly the same behavior as before. My battery continue to drain really fast, as you can see in the attached picture.

My X98 version is C9J8.

Hearthstone is slow because Hearthstone is completely unoptimized crap. Well, the client is, the game is pretty fun. But the game itself just runs like a dog even on my great PC (relative to how it should run). As you've likely noticed, it isn't so bad when you're actually playing a match.

I'm not sure if it matters, but you're using an old version of IMT. Try using 6.0.43. Also, did you copy the custom config.ini file to the IMT installation directory?
[Teclast X98 Air 3G] blasti99:
I compared the tPAD107 and tPAD202 bios and noticed that there are not that many differences:

- some modules have been moved to different locations.

- The only big addition in tPAD202 seem to be an EFI-Shell module, but I am not sure if that is actually usable ?!?

in my tPAD107 it does not work when I select boot to EFI Shell in the BIOS screen... which seems to be expected since the module is missing :D

I checked the TXE parts of all flash-dumps that I could find.

since version tPAD103 TXE 1.1.1.1120 (VCN 11) is used.

tPAD202 has TXE 1.1.1.1130 (VCN 12)

my understanding is that the TXE parts contains the firmware for the baytrail that handles the sleepmode, so it might be just the new TXE which fixes the battery drain on windows.

updating just the TXE firmware might be a safer way to get this fixed.

the post from ujensen pretty much confirmed by suspicion that the bricks are not caused by incompatible bios but by a bad flash procedure.

from reading the documentation of the intel firmware tools I saw that none of them is compatible with Windows 7 ... so that might be one reason for the bricks.
[Teclast X98 Air 3G] colo4you:
Your drain issue is not from the bios. It's from one of your driver that cannot start the low power mode in the tablet sleep mode. Try to up date driver

a nice guide to do just that can be found here:

http://chinamobilemag.com/bios-fix-pipo-w1-cube-iwork-10-intel-atom-z3740d-tablets/

1.Basically you make a backup of your current BIOS

2.Flash new BIOS

3.Restore BIOS from the backup you made but leave MEI untouched

You can also get the BIOS utility here:http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_bios/9hjy53usb.exe

If this is the case how come when installing dual boot bios we have drain but when installing air 2 bios drain disappears with out changing any driver in windows?Maybe because the only difference is that air 2 does not list the GPS??So could the GPS cause the drain??
[Teclast X98 Air 3G] johanw90:
what is the best rom at this moment?
[Teclast X98 Air 3G] colo4you:
The best one is DualOS C5J6 v2.02 (GPS and autofocus do not work on Lollipop. Not sure if it works on Kitkat) however, there are some risk to brick your tablet which is still an unsolved problem.

For a safer path, WinOS HG6N v1.03 is also good one for Windows only system. However, you will not be able to use Android OS, GPS and front camera.

---------- Post added at 03:31 PM ---------- Previous post was at 03:24 PM ----------

I don't think GPS cause the drain because which GPS works in v2.02 (only Windows mode) perfectly. However, ujensen's issue was different because according to his screenshot, there is an unknown device preventing Windows to go into connected standby mode 100%. So his problem was not about BIOS.

I think sometime when we change a BIOS, Windows thought that some devices had been changed (It might be related to some descriptions about hardware in the BIOS data???) and reinstall them. It happened to me when I moved to v2.02 BIOS.

---------- Post added at 04:01 PM ---------- Previous post was at 03:31 PM ----------

That was my first assumption because TXE runs independently from the main OS and CPU. However, from the fact that BIOS v1.07 uses the same TXE version as v1.03 (TXE v1.1.1.1120). I don't think TXE version is the root cause of the problem.

Actually, there is one thing I guess that it might cause this drain issue. It's about the execution mode of UEFI. For the moment, Windows only supports 32 bits UEFI code (x86). (You can notice that the Windows must be 32bit running on 64 bits Intel Atom CPU. Don't ask me a reason. I don't know too... I only saw someone mentions on a forum that "connected standby" only works with 32 bits UEFI which only works with Windows 32 bits) However, Intel Android for x86 (only??) supports 64 bits UEFI code (x86_64). So the DualOS BIOS/UEFI will be quite complex because it need to find a way to handle both 32 and 64 bits in the binary code. Anyway, it's just a guess without any proof :p
[Teclast X98 Air 3G] ZeAuReLiEn:
I installed the 2.02 bios and I still use Kitkat : no autofocus issue (didn't test GPS).

So it is related to the ROM

Custom Rom or stock

Hey guys, I have a small question :confused:

I bought the 64GB dualOS-Version of the 3G and I wanted to install the custom rom from mirek190, but with the lollipop beta update, Im not sure about it now. Is it easier to upgrade from stock rom 4.4 to stock lollipop (when available, not beta) as from custom rom (mirek190) to lollipop? I dont want a full wipe when i change from 4.4 to lollipop.

Thanks :)
[Teclast X98 Air 3G] Wallace4793:
Hi,

Yes I have tried all of the recommendations to solve the IMT failing at 5%

1. Custom Config in the correct place

2. ADB drivers installed and showing as working correctly in device manager

3. IMT PID values are correct.

4. I've tried old and new IMT

5. I've now tried 2 cables.

6. DNX mode confirmed.

7. Toolbox script not working. The device does not appear in "ADB Devices", ie it is somehow not recognized properly in windows even though it is showing up. For the record "Fastboot Devices" command does show the baytrail info. I'm not sure what the difference is between Fastboot ane ADB.

I guess my only real option to flash again is via the programmer which is not something I really want to do. I can only assume that my bios is somehow not able to flash anymore :(

Nightmare.
[Teclast X98 Air 3G] benbraun322:
Wait your Windows is working?

Maybe you should try to flash your BIOS From Windows. Make sure your battery is fully charged, and flash a BIOS.

Then attempt to flash android with partitioning again.

Hi,

I've flashed to windows now and cannot get android back on the tablet (IMT sticks at 5% - I've tried all the fixes) I also have the 7% battery issue.

I have a few questions :

1. Is the battery reporting bug a bios issue?

2. Is it limited to windows roms.... Or would I still have this issue if I was on android

3. Is there a bios which fixes the battery drain in windows? I've seen some discussion on TXE but some people are reporting some bios don't exhibit the issue.

PS I have an Air II (H6GN)

Thanks
