So close to Dual Boot!

EDIT: We already have dual boot. Check out from HERE

Old message:

Hi!

I have almost working dual boot on my Teclast X98 3G (HK1). I have installed Windows 10 Pro (32-bit) AND Android x86 4.4-r3. I installed Android using Android-x86 Installer (UEFI Version). The Android 4.4 boots up nicely but there is one BIG problem. Android doesn't detect power supply or battery so when the Android boots up (the language menu appears) it will immediately force shutdown. It doesn't matter if usb charger is connected or not. It will always shutdown.

This might be some kind of driver issue so does anyone know where I could find other battery drivers for Teclast X98 3G for testing? Then we could finally have dual boot system!

There is newer Android x86 5.1-rc1 but it doesn't boot at all. Same thing goes for Remix OS.

EDIT: Now I'm able to boot Lollipop! I made ext4 partition to my hard drive and now Lollipop is able to boot! However the tablet turns off immediately since it doesn't detect battery. It shows 0%.

Fully working 3G connection on Windows 10

How to make 3G connection working in Windows 10 on Teclast X98 3G:

First check out the Windows 10 info. You need a Teclast BIOS 11.09.2014. (Onda 911 doesn't have 3G support).

Install 3G drivers (Comneon_High_Speed_Modem_Driver)

Use compatibility mode: right-click on "Setup.exe" => properties => compatibility => Windows 7 => OK, and then double-click "Setup.exe" to install the driver

Open the Control Panel

Select Phone and Modem

Switch to the "Modem" tab

Click "Properties"

Click "change settings"

Switch to the "Advanced" tab

Enter the "Extra initialization commands" in the following command, Replace the access point name to your carrier (mine was "internet.saunalahti" in Finland):

AT+CGDCONT=1,"IP","access point name"

Click determine

Re-open the modem properties, and switch to the "Diagnostics tab"

Click on "Query Modem"

There should be "success" and something like: + GMM: "H350 HSPA + Module", "H350",

APN setting is completed then open the Control Panel

Select the "Network and Sharing Center"

Set up a new connection or network

Connect to the internet => Next

Set up a new connection (if not connected to a network, skip this step)

Dialing (using the dial-up modem or ISDN connections)

Fill dial a phone number "* 99 #" without the quotes, leave the others empty, then => Next

Done!

Original guide HERE.

If you want a 3G connection strenght bar you can use this software:

SimStatus.rar (20.74 KB)

SimStatus_With_PPP.rar (12.93 KB), this one did not work for me

EDIT: Possibly found working Android x86 files for Teclast X98 3G: No, same force shutdown problem... :(

http://pan.baidu.com/share/link?sha...%E7%B3%BB%E7%BB%9F%E5%86%B7%E5%90%AF%E5%8A%A8

Downloading is just damn slow

I found a hacky way to dual boot Android and Windows. You can find the guide from Teclast forum HERE. The download links are dead so we can't use them. However we basicly have everything that we need.

[IMG="Hacky way Dual Boot"]http://bbs.teclast.com/data/attachment/forum/201411/25/220935m7q3keqll7w7tp2m.jpg[/IMG]

Another way to Dual Boot is to use Android x86 build. I'm currently working on this. I found that Carbon Jiao made a "working" build for Teclas X98 3G. Check it out HERE. Carbon Jiao managed to solve "force shutdown" problem which I'm currently suffering.

[Device Reviews and Information] Zereus:
Wow sounds great.

Maybe i can provide drivers from my running HKC1. maybe we can load some drivers in android x86.
[Device Reviews and Information] Flash-A-Holic:
Working Dual Boot (Win 10 and Android 4.4)

No Lollipop yet but finally a working dual boot (Android x86 4.4.4)! I believe that we are now able to run Lollipop 5.1 also but there is some work to do.

UPDATED 24.5.2016

Now we have working Marshmallow 6.0.1 and CM13 builds. You can find it from HERE.

Here is a working build for Teclast X98 3G (HKC1): android_x86_4.4_r3_Onda_V975i_V2 (284.7MB)

Working: Touch, WiFi, sounds, sd-card, battery level indicator, power and home buttons, video acceleration, brightness control, accelerometer (but it is upside down)

Not working: 3G, bluetooth, cameras, volume buttons

This build has

GAPPS

installed and NO force shutdown anymore :). Here is a short guide:

Make a FAT32 partition to your main drive using MiniTool Partition Wizard. (I made 8Gb)

Install Android x86 4.4-r3 EFI to FAT32 partition using Android-x86 Installer UEFI Version. (I selected 3.5Gb for "Data size")

With this method we get touch drivers from 4.4-r3 build and easier install process. (Previously method had laggy touch)

After installation copy and replace "kernel", "initrd", "ramdisk" and "system" from "android_x86_4.4_r3_Onda_V975i_V2" folder to "AndroidOS" folder. Then delete system.sfs from "AndroidOS" folder

Then reboot to Android like this:

Open Settings, and click on the Update & security icon.

Click on Recovery on the left side, and click on Restart now under Advanced startup on the right side.

Select "Use a device"

Select "Android-OS"

Now your tablet will reboot to Android

I have made

a shotcut

to the desktop which leads me directly to the step 3. Select "Use a device". You can download Advanced_Startup_shortcut.zip from HERE.

We are able to fix volume buttons since they are working on this build: android-x86-kitkat-rtl8723bs-kernel_3.18.2 (333M). There is also sources for bluetooth so it should be possible to fix it. However I think that we are not able to fix cameras and 3G.

For Lollipop we need to rebuild drivers from android_x86_4.4_r3_Onda_V975i_V2 to Android x86 5.1-rc1. That is not easy job but possible. There is already Lollipop 5.0.2 builds which

partly works

on our tablet:

android_5.0.2x86.iso (338M)

Working: WiFi, Touch

Not working: Sound, Video Acceleration

android_x86-5.0.2-knr18.iso (252M)

Working: Touch, Video Acceleration

Not working: WiFi, Sound

android_x86_5.0.2-knrl3.18+gapps.iso (367M)

Working: Touch, Video Acceleration

Not working: WiFi, Sound
[Device Reviews and Information] Zereus:
connect a usb hub with keyboard and windows boot stick. press "delete" during boot. in bios use boot from usb and Windows will install.

has anyone the problem with extreme battery drain with windows 10? i have to power off the tablet to charge. with Windows running, even in power save, the charging current is to lower than what the tablet needs.
[Device Reviews and Information] Flash-A-Holic:
I did have that problem but this fixed it. Have you done this yet?

BTW I found fix for upside down accelerometer on Android x86. Still need to figure out how to implent. I have also tried to collect needed drivers for Lollipop build and I have found some:

WiFi: https://github.com/hadess/rtl8723bs

Touchscreen: https://github.com/hadess/gt9xx

Accelometer: https://github.com/hadess/iio-sensor-proxy

Sound: https://github.com/AdamWill/baytrail-m/blob/master/alsa/t100_B.state

Battery patch: https://bugzilla.kernel.org/attachment.cgi?id=179931&action=diff

Since I don't have much spare time I can't rebuild Lollipop right now. Actually I don't even have proper skills for development yet. However I'm planning to do it later. Now I'm trying to get Lollipop 5.0.2 build to work on our tablet.

My plan is to swap needed files from working 4.4.4 build. I already have WiFi file: r8723bs.ko. Still looking for sound. Then we could have Lollipop 5.0.2 with working Touch, Wifi, Sound and Video Acceleration. Not perfect but something.
[Device Reviews and Information] Zereus:
i already changed the driver. didnt help... maybe i need to install the wifi driver also?

edut: or is bios update necessary?
[Device Reviews and Information] Flash-A-Holic:
I have Teclast BIOS 11.09.2014 and no battery drain after fix. EDIT: I have also updated WiFi driver.
[Device Reviews and Information] Zereus:
thank you i will try this.

one question to dualboot. android x86 uses grub loader?

do i need a keyboard to choose the OS? Or is it possible with touch/buttons?
[Device Reviews and Information] Linus303:
seems good. But how much is this:)
[Device Reviews and Information] Flash-A-Holic:
Currently I'm using Android-x86 Installer UEFI Version for installation. It makes the needed Grub entry automatically. With this method we are able to boot from Windows to Android without using external keyboard:

Open Settings, and click on the Update & security icon.

Click on Recovery on the left side, and click on Restart now under Advanced startup on the right side.

Select "Use a device"

Select "Android-OS"

Now your tablet will reboot to Android

If you have keyboard then you can boot from BIOS to Android or use this method from Windows:

There is also Gummiboot option but I haven't try that yet.
[Device Reviews and Information] minchas77:
Thanks for your work Flash-A-Holic. It looks great already. Hope you have luck with the accelerometer and the Lollipop build. Just a couple of questions:

- You have installed Windows 10 first. Have you followed any specific guide or is there any step we absolutely need to follow?

- How is performance in KitKat? Does it go to Deep Sleep? (any comment on battery life would be great)

- Any major issue with app compatibility?

Thanks!
[Device Reviews and Information] Flash-A-Holic:
I have installed Windows 10 but it is not necessary. Android x86 should work with Windows 8.1 also. Althought I have only tested it with Windows 10 on Teclast x98 3G and with Windows 7 on my laptop. When I installed Windows 10 I followed this guide:

TECLAST X98 3G, Allview Viva/Impera i10G Windows - Final version! Fully tested!

Then you just need to make FAT32 partition with MiniTool Partition Wizard and follow guide that I wrote earlier:

Working Dual Boot (Win 10 and Android 4.4)

The performance on Android x86 is better than the "native Android" I think. However battery life is not very good. I believe that the deep sleep is not working :(. The stock internet browser will crash sometimes but Chrome is working perfectly. Also Play Store had some issues once but reinstall solved those problems. I haven’t noticed any other problems (excluding hardware issues: 3G, bluetooth, cameras, volume buttons and upside down accelerometer).

I already managed to fix accelerometer once but then I lost touch. I need to figure out what happaned. No luck with Lollipop yet. I have the last exam for this season next week so I'm little bit busy right now but after that I will try to fix everything that I can.
[Device Reviews and Information] minchas77:
Great post, thanks!

I will try to test the KK build next weekend. Pity about the Deep Sleep. This is the exact same problem all official roms (Teclast / Viva / 9PV 3G) have. It's a battery killer...
[Device Reviews and Information] Flash-A-Holic:
KitKat build is the most stable and good enough everyday use. Too bad that accelometer is upside down. I will try to fix it later. (You can use Rotation Control untill it is fixed). For deep sleep there is very little that I can do.

Good news are that the new kernel has a fix for the force shutdown problem on our tablet. So we should have a lot of new builds to test!

There is new CM13 build out for testing: CyanogenMod_13_x86_20160521. I haven't have time to test it yet. There should be GAPPS included and the accelometer should be working. However it can be 90 degrees wrong. I can fix it easily if that is the case. (Accelometer is easier to fix in MM than in KK).

Now my goal is to fix sd-card reader in MM build.
[Device Reviews and Information] jonnie77:
After updating all view front camera is upside down?any fix?

[Device Reviews and Information] Flash-A-Holic:
Have you updated drivers? For temporal fix you can use manycam with Skype etc. Just google it for instructions
[Device Reviews and Information] mihaiolimpiu:
Hi guys, this is my last update to this thread, I upgraded to an Teclast X98 Plus 3G.

Just some final thoughts:

Allview Viva i10G (Probably original Teclast x98 3G) uses FocalTech Touch. I don't know if on my tablet the touch is broken or if it's just a driver problem but I'm tired of it, I'm a very heavy Windows User, so I need it to work every time I need it.

I found that disabling sleep mode on the I2C HID device makes the touch way, way more stable, but sometimes , there are some areas (at least on my tablet) that miss the touch... a quick sleep/wake cycle fixes it and preventing I2C HID device form sleeping made it a very rare appearance.

Also completed the tutorial with a quick and dirty Android conversion, and how to fix usual problems! I bricked the tablet 10-15 times last time I did it so be sure to follow those steps!

Still I need something better. It's a real disappointment because usually FocalTech Touches are considered better than Goodix ones.

I'll do a quick check of my tutorial to see if everything is still up to date then I'll move on.

The tablet is great, only thing is missing is dual boot (I understand there are some great advances on this front) and a 100% stable touch in windows.
[Device Reviews and Information] Mi_ka:
Thanx for the posts so far!

I hope the new 'blet will serve you well! If you do not mind drop a line in comparison to our not-plus model.

I guess no 5.0 upgrade anywhere? Since I do not expect any updates by Allview I was hoping to see this happening *maybe by you?) one day as the hardware is just too capable to be stuck in the 4.4.2 limbo. For me this has been the main reason to be staying in the Apple fenced garden: No official updates after 6 months-1 year tops by most Android related tablet companies means that in the long run the Apples cost the same per year of ownership since you do not change them that often. If you can take the Apple sweet tyrrany that is... Tweaking is very nice but peace of mind is nicer and the 4.4.2 is just long in the tooth now and however nice the windows 10 mod you have posted may be, Windows and I have (mostly) parted ways for good now.

Hi,

I've instaled win 8.1 and I've tried to preapere partition for androidx86. Unfortunately after rebooting there is screen titled Automatic Repair and two option: first Restart and second Advanced Options. But touch screen doesn't work. Mouse and keybord connected to usb don't work eithr. Any idea how to select one of this options? Or restart windows?
[Device Reviews and Information] zendop:
Hi All,

I just bought (and prepare to return) an Allview Impera i10G (Teclast X98 3G).

This one is a re-branded Teclast and delivered out of the box with Win8.1 unlike (maybe) same hardware Allview Viva i10G that runs Android out of the box.

I still want to give the tablet a chance, but...

I want to revive post #561 (later #586-#588), so: has anyone solved the problem?

http://xdaforums.com/showpost.php?p=63571801&postcount=561

Two workarounds but not a solution:

1) Disable EIST (Intel SpeedStep) - this partly solves the problem but core 3 and 4 still goes to .48Ghz after one minute.

2) Disable All setting related to CPU C states - this keeps all the cores to 1.33

FYI: Z3735D does not support Dynamic Frequency scaling (aka EIST, aka Intel Speedstep) anyway, Teclast just cheated with 0.48 Ghz when EIST is enabled (just think about what manufacturers can do without your knowledge in bios)

The bad: this is a workaround but the battery receives a heavy hit and the tablet becomes hot (becomes a "desktop"), not right away but after some time.

The good: you can actually use the tablet, I really like it.

[MENTION=1379846]jlname[/MENTION] (post #581) Your post relates to the 0.48Ghz problem

P.S. My Bios version is 12/10/2014
[Device Reviews and Information] Zereus:
I tried to go back to android because windows is just unuseable, intel atom is just too weak.

I flashed "Rom_8MB_Tablet_Android" from your box (thought it was teclast). now i only get the intel logo. No chance for fastboot?

How did you unbrick?

edit: just a driver problem....

ohhhh why cant i just kill this thing, it's stealing my time :-p

edit2:

dont flash teclast 116 if you want upgrade to 4.4.2.. touch isnt working after upgrade. I think I'll try teclast 111
[Device Reviews and Information] melidron:
intel inside logo stuck

hello from Greece

I have Viva i10g and tried the easy install guide (from mihaiolimpiu) to upgrad to windows 8.1

at step "d" i couldnt flash the firmware Teclast Android ROM 116 so i skipped this step as he proposes to do...

He also says that if you dont flash 116 there is no other way to make touch work

I manage to install original teclast windows bios and then windows 8.1

touch and some other features didnt work

I used a windows 10 usb stick and installed windows 10 ( i deleted all partitions and created a new one with windows 10)

I searched drivers in here and made it work everything but the touch

So the only way to try was to flash android bios (Rom_8MB_Tablet_Android.bin) from fptw_NEW.zip folder of Mihai google drive using fptw tool and when I restarted the tablet it only shows "Intel Inside Logo"

My PC see it as a "Baytrail" device (no idea what is this) I tried flash "TECLAST android 116 rom" with Manufacturing Flash Tool holding the 3 buttons power vol+ Vol - but it terminates the flashing at 5% saying droidboot boot failure

Is my tablet bricked or there is still hope?
[Device Reviews and Information] mihaiolimpiu:
I'm afraid you need to flash the bios with a flasher. Until you find one, just try, try again, on mine it booted once in 100 tries when it happened (or so I think), the conversion back is sometimes problematic... I wouldn't advise someone to try Windows -> Android without a hardware flasher ready.

I don't know why sometimes it happens (bad flash?) but It happened to me several times, and usually when converting back to Android.

On my original tablet it went flawlessly, on a borrowed one it got bricked....

I don't know if it helps or not, but until someone gives you a better answer, just try to find someone with a hardware flasher.
[Device Reviews and Information] melidron:
i was so lucky :)

I was so lucky cause i tried flash "116" with Manufacturing Flash Tool on my wifes laptop and I manage to convert it back to Teclast andoid and then I followed the steps d - f on your Easy install Guide and Managed to install Windows Bios again

I didnt used your windows 8.1 files and then Upgrade to 10. I Installed Windows 10 from a usb stick I had...It didnt let me to chooce 64bit version (i dont know why it said it dont support it cause Viva's i10g cpu is 64bit)

I ended up with a new version of windows 10 32bit, install all the official updates nd the touch work perfectly...with the updates all devices work perfectly except rotation sensor camera audio and 3g which with your Impera i10g drivers made everything work... Thank U so much for your guide and your help in here I had a useless tablet with android system and a battery that drained in about an hour and now I have windows 10 inside and battery last almost 7 hours continiously open screen and updates all the time :) By the way Your last name Olimpiu seems so Greek name :)
[Device Reviews and Information] melidron:
CPU stuck at 0.49 GHz

The only problem now is that CPU is stucked between 0,48 - 0,49 GHz

It makes tablet a little slow is there a fix for that

Tablet is VIVA i10g with windows 10 inside (followed the easy install guide from Mihai Olimpiu) everything else work nice except CPU speed

Thanks

I installed viva i10g firmware on teclast x98 3g and after 2 days noticed a green tint arrount my screen more visible with dark colors. I noticed that IFWI now is 1.45 ( whatever this is I don't know) reverted to android 4.2 teclast firmware by first writing bios 4.2 with bios chip programmer and e green tint goes away. I would like some hell if anyone still active because viva i10g is more stable.

Thank you

P.s. who can explain me what IFWI version is? I can't find anything about it.

I believe it is simply glued on and can be removed with the help of a hairdryer.

Can anyone supply the part number so that I can order it without dismantling it first?
