Has anyone got the dual boot files outside of Baidu, as I don't want to mess about registering for it.
[Windows 8 General] jockyw2001:
There is no need for signing up with Baidu. You can use this version of JDownloader2 to download all files.

Run JDownloader and copy this url to your clipboard: http://pan.baidu.com/s/1c0EmSIc

JDownloader2 will show 4 files for download.

I just Flash Bios from baidu. Flashing fpt32.efi successfully but flashing fpt64.efi failed.

"image type x64 is not supported by this ia32 shell"

After reset tablet display fail,but tablet work properly by connect through HDMI.

I think my problem is bios resolution wrong.

Any have another bios file.

Thank you.
[Windows 8 General] Skanob:
If the bios/uefi is 64-bit, then that must mean you can now install 64bit Windows on it? Have you tried that? And is Macrium Reflect Free version enough to back up the entirety of the tablet?

I've already ordered one of these devices from banggood, couldn't wait for it to arrive.
[Windows 8 General] jockyw2001:
Haven't tried installing 64bit Windows yet, but theoretically that should work. In practice it means finding 64bit drivers and changing a few bios parameters (there are a few bios params depending on the boot state).

Yes Reflect Free Edition can do a full backup/restore. I store the backup images on a 128GB microSD and boot Reflect of a USB stick. I did have to add Voyo touch, pmic and some other drivers to the boot stick. How that is done is quite well described here
[Windows 8 General] jockyw2001:
The dual-boot bios can boot up in 64bit or 32bit mode. If it boots up in 32bit mode then fpt32.efi will flash a new uefi/bios and fpt64.efi fails and if it boots up in 64bit mode it is the other way around. Nothing to worry about.

I didn't have any display problems after flashing the dual-boot bios. I bought my 5v2a Voyo in Oct'14 and there was a bios of Sep'2014 preinstalled on it. I think I posted a dump of that firmware some time ago, not sure about that.
[Windows 8 General] Milardo:
Hi, i flashed bios with dualboot bios. How does one get the bios to boot in 64 bit mode? I'm wanting to try to install win 7 x64. I wasn't able to flash the bios with fpt64.efi yet because i also got the shell problem.

Problem after install BIOS

Hello,

I Flash Bios from baidu for Dual Boot. Flashing fpt32.efi successfully but flashing fpt64.efi failed : image type x64 is not supported by this ia32 shell.

After reboot, I have a problem with the display (photo attachment), but tablet work properly by connect through HDMI.

I wonder if someone have the same problem or if someone have a file of original BIOS ?

Thank you

(Sorry for my english)
[Windows 8 General] jockyw2001:
The answer is 2 posts above yours

Your new dual-boot bios is flashed correctly, you can ignore the error you got with the 64-bit flasher.

Old bioses have been posted before somewhere in this thread I believe
[Windows 8 General] zucco25:
I install Windows and start correctly, the problem is the screen : is black with white stripes. On my preview post, the photo was taken when Windows was started. But the screen is blank. But when I connect to the TV with HDMI it works.

I have access to the BIOS, the menu to select the OS and Windows but only on HDMI. I wondered if it was because I could not flash the BIOS in x64 but from what you say, it does not a problem.
[Windows 8 General] furer:
No, it's not. Some of the z3735f voyo-s are just not working properly with dual-boot BIOS. If you have made the backup of your original firmware before flashing dual-boot firmware - just flash it back with fptw.
[Windows 8 General] zucco25:
Arf, I have a Z3735F and I don't make a backup (we leanrs from mistakes !) :(

Is it possible to find an original firmware and flash it ? Maybe someone have one...

In the worst case, i can use the tablet as a PC with HDMI, she's not definitively dead.
[Windows 8 General] furer:
Well, I had the same situation. There is a post with pak of original firmware here but files are no longer available on mega.co.nz: http://xdaforums.com/showpost.php?p=59796233&postcount=449 :( Only capable firmware I found was test1.6.3. on 4pda.ru. In my case it worked. Everything seems to work fine except from the front camera. To flash it with ftpw: put the test163.bin file to the fptw directory, run cmd.exe as an Administrator in Win and go to the fptw directory then run command "fptw.exe -f test163.bin". Wait until process ends and reboot. To backup your current firmware run "fptw.exe -d <filename>.bin". There is always some risk to get a break when you flash not original firmware! And you should backup your windows activation key with "Windows 9 Product Key Viewer" because activation can be lost after flasing.
[Windows 8 General] jockyw2001:
I have stored the bios pack on my google drive. There is also a backup of my original bios (sep 2014) made with AFUWIN. I will keep the files there for a couple of days. Get them here
[Windows 8 General] zucco25:
Thank you very much ! :) I would try the firmware once go home. I'll let you know.
[Windows 8 General] Skanob:
I realized the driver problem. Hhmm. I wonder if voyo or someone has made a 64 bit driver for it? I'm pretty sure it'll not give it a boost in terms of speed (lack of RAM). Just might be useful as the processor is 64bit compatible.
[Windows 8 General] jockyw2001:
You can find most of the 64bit windows baytrail drivers on the Lenovo support site for the Thinkpad Tablet 8 or 10. The way to go is to switch tablet to 64bit mode and enter bios/uefi and then boot a 64bit installer from a usb drive.
[Windows 8 General] Skanob:
Really? do they have the same hardware in everything?
[Windows 8 General] Milardo:
Hi jockyw2001, can you show how to switch tablet to 64 bit mode?
[Windows 8 General] Milardo:
Anybody know?
[Windows 8 General] jockyw2001:
After installing dual-boot bios there is a graphical boot menu which shows android (64bit mode) and windows (32bit mode) icons. That menu can be operated with the touchscreen and includes an icon for entering BIOS. In the case you don't see that menu, you can try the following sequence: power off tablet, power on while at same time keep the Volume- and Volume+ buttons pressed. That switches to 64-bit mode and you can enter bios to boot a usb installer. You can also try to reinstall bios if you don't see the menu. Before installing the dual-boot bios I recommend to note down or take photos of all your current bios settings and also to make a backup of your current bios.
[Windows 8 General] Milardo:
Thanks a lot! With that sequence, i was able to boot a win 8 (have not tested win 8.1 yet) x64 dvd and installed sucessfully, however the os/bom keeps switching to win 8.1 instead of staying in android mode sometimes. Haven't yet installed x64 drivers but have acquired them from the lenovo site. Tried to install win 7 x64 and keeps getting stuck at the "loading files" screen for some reason when you boot from dvd. When you try to install win 7 x64 dvd from win 8 x64 os it needs a driver some standard sda host complaint controller driver. I was able to acquire the right driver for win 7 x86 when i also tried to install it from win 8.1 x86 for testing but so far i am still looking for win 7 x64 version. Any more help appreciated and from anybody who is also trying this.
[Windows 8 General] Skanob:
Which version of win 8.1 dvd are you using? Imight recommend trying with a windows 8.1 update 3 (november update) dvd and see if it works. Google will show you where to get the .iso.

Can't wait to get mine. Hopefully be shipping this week.
[Windows 8 General] jockyw2001:
Don't you get the graphical menu?

In 64bit android mode some bios/firmware settings are preset and differ from the 32bit windows bios settings. You should make a note of these and after doing that make sure you update those specific 64bit settings to the 32bit settings. A couple are usb otg enabled, usb vbus off, isp device selection B03F0. There may be more.
[Windows 8 General] Milardo:
I tried a couple of versions but im getting an update error.

I tried to search for that particular iso but don't know where to find it, perhaps you can provide a link or so?

---------- Post added at 06:47 PM ---------- Previous post was at 06:43 PM ----------

Almost everytime i restart win 8 x64 it seems to just to want to go back to win 8.1 32 bit mode. Also i had the graphical menu originally on first bios update but i messed with the bootloader which made it disappear and also i have no efi shell on filesystem either? I have to put one on usb to get it. How do install a efi shell for both 32 bit and x64? After that i reupdated bios of 32 bit and then got the graphical menu and also i updated bios of x64 too. However, now im not getting graphical menu anymore. I set some 32 bit settings like in x64 mode but it isnt helping.
[Windows 8 General] Skanob:
There's a lot of ways to do it. One of the best ways to do it is by using the media creation tool. Then there are "unofficial" ways, which I'll not post.
[Windows 8 General] TehMajoo:
Hi I have a problem with the dual boot tutorial:

When i write ftp32, tablet says: ERROR: ACCESS DENIED. I tried with many pens and many formats but I don´t get it.

Thanks a lot.
[Windows 8 General] jockyw2001:
In the bios security menu set disable secure boot and try again. There is also a bios write protect setting which should be disabled too.
[Windows 8 General] jockyw2001:
In case the graphical dual-boot menu does not show up anymore, go into bios and restore settings. Don't forget to change the devices to your original configured devices and then do save and reset. That worked for me after I had lost it.
[Windows 8 General] TehMajoo:
Hi!

I have another problem, when I reset the tablet, appear something like that bitlocker recovery. I dont know who is that and I cannot do anything.

Thanks!
[Windows 8 General] Milardo:
I tried the media creation tool not sure if it is the latest version but i am still getting the update error and not being able to install 8.1 x64 only win 8 x64, and still not win 7 x64. Able else trying this yet?
[Windows 8 General] TehMajoo:
Hi Jocky again, when I write fpt32.efi -f I need to put ENTER TO continue, but the last time, I have a ERROR 200: Invalid parameter value specified by yser and ERROR log is not created because tool is likely running on a read-only media.

Thanks bro! :D
[Windows 8 General] Milardo:
Hi, did you put the name of the bin file as well after "-f" ?
[Windows 8 General] TehMajoo:
Yeah, i put this.
[Windows 8 General] Skanob:
It should be update 3 that you've downloaded. Try to grab the .iso then.

Unless there's a settings in the bios that needs to be changed.

Have you tried installing Windows 8 then upgrading to Windows 8.1?
[Windows 8 General] Milardo:
I've used the usb but the iso on dvd probably wont make a difference.

Its possible there is a bios setting but i dont know what to set.

Yes i've tried to upgrade as well. I might try again to do a complete clean install when i get a chance- deleting partitions etc. I was trying to also test the win 8.1 x64 drivers from lenovo site- thinkpad 8-intel chipset drivers on win 8 but keep getting a compliance message .

iso converted to usb installer using Windows USB/DVD Tool?
[Windows 8 General] Crempa:
Forgotten Windows administrator password

Hi all,

I forgot Windows admin password and I don't know ho solve it now :(

- I used local Windows account so its not possible to reset it online

- I tried pogostick.net/~pnh/ntpasswd/bootdisk.html reset disk, but voyo don't want to boot it

- I'm able to boot Ubuntu from USB and it's possible to reset Windows password from linux with chntpw BUT I can't mount Windows partition in Ubuntu

So, some advices? :)

- Is it possible to recover Windows partition to default factory state? (I don't have any valuable data here, so there is no problem with complete erase)

- or some experiencies with mounting voyos mmc paritions in linux?

- or some another advice?

Thanks!
[Windows 8 General] jockyw2001:
With Fedlet I was able to mount the Windows system partition.
[Windows 8 General] jockyw2001:
Yesterday I thought I had bricked my Voyo and opened it up in order to disconnect the battery. Luckily for me it was simply an empty battery. Anyhow I made the attached photo and you can see the board is (still) made by EMDOOR and the board version# is EM_I8080_V6.1. Interesting is the name of the daughter board at the bottom: "EM_I8080_3GMODULE_V3.1". I didn't check what components are on that board. My tablet is definitely not a A1 Mini 3G, but perhaps my A1 Mini has the same hardware. There is a 5000mAh battery inside.
[Windows 8 General] Skanob:
Got my tablet today. In order to do a proper Macrium Reflect (Free Edition) back up and restore, do I just only need the installer, or should I download the PE Components too? Will the 16gb flash disk enough to back it up? I reckon it should not backup blank space.
[Windows 8 General] jockyw2001:
Install Macrium Reflect Free Edition on your PC and create a bootable rescue USB stick with it. Then replace the boot.wim with the one which I uploaded to my Google Drive. A full backup with maximum compression and sector-by-sector mode (non-intelligent mode) will probably be around 5-6GB.
[Windows 8 General] Skanob:
That wouldn't be the case for me, I ordered a single OS Windows 8.1 version, but they've sent me a dual-boot OS. You might say it's all good that I've got dual boot, but I would rather have single boot than dual, I have no use of an android tablet, I've already got my android phones for that. I'll post a screenie of the partitioning of the emmc that I've got. I would rather, though, back up the whole thing before converting to single OS.

Edit:

[IMG="drive partition"]http://i.imgur.com/nKpRvzS.png?1[/IMG]

Drive D: is my 32GB SD Card.

Want to clean it up with a WIMBoot installation after back up. Will also try x64 bit installation, I got me the Windows 8.1 November iso ready both on x86 and x64.
[Windows 8 General] jockyw2001:
It's really easy to install a single boot Windows. You can just run the Windows installer. I presume you already downloaded the WIMboot files from Baidu (they are in the dual boot package). Readout the product key before you install it. It takes no more than about 20-30 minutes for the full backup and another 20-30 minutes for installing Windows. I know the dual-boot partition scheme by heart, no need to post it :)
[Windows 8 General] Skanob:
Nice! I will download them WIMBoot from Baidu (has someone mirrored it?) (found it). And also do a backup of the original partition too, in any case (worst case scenario). I might try installing x64 or x86 with PRO on it first, then afterwards WIMBoot it. To which ever works.

Haven't heard any progress from the other guy for x64 installation and driver compatibility.

Edit:

Unfortunately, the maximum flash disk that I've got is 8GB, I don't think it'll be enough to back up both OS. Windows itself is around 5~6gb, i would assume. I'll be getting a 16gb and 32gb flash disk asap tomorrow.

Edit 2:

Has someone posted a collection of things that can be done on the tablet? i.e. button combinations, access recovery mode for android, tips and tricks maybe, etc.

Edit 3:

Speaking of android, I might root it first, then gapps, then backup. :D

Edit 4:

What is the latest UEFI version? Mine goes like this:
[Windows 8 General] jockyw2001:
I think it is possible to install a win-x64, but it is important to set a few 64-bit bios settings support windows. I listed a few already and will try to post all of them later.

You only need the 3.4GB Win-x86 from Baidu. Use JDowenloader 2 to get it.

Can you look up the installed bios and android versions on your tablet please. Thx.
[Windows 8 General] jockyw2001:
It will fit. The whole lot is 6.6GB

I've gapped, rooted and added a reasonable recovery. Will post that this week.
[Windows 8 General] Skanob:
Custom recovery? Nice! What's the latest BIOS/UEFI version?

Mine is:

Android goes:
[Windows 8 General] jockyw2001:
It seems the usb port only supports otg devices (kb, mouse, storage, etc). I haven't discovered yet how to configure it to slave mode so that it can connect to a PC. To resolve that I added network support in boot/recovery/fastboot. So plug in an ethernet-usb dongle and connect via the network (voyo ip = 192.168.42.1). ADB already works this way, but fastboot and adb sideload not yet. Must fix that before I upload it.

Mine is the same version. Android version also the same.
[Windows 8 General] Skanob:
Could a change in bios settings be needed? Hhmm. You've got tools in your disposal. :good:
[Windows 8 General] jockyw2001:
I nearly exhaustively tried all. I think there is another internal USB port which Voyo did not bother to add a socket for, that could have been the slave port. I also tried different cables with and without ID pin, all to no avail. Would be nice if you can test usb connectivity with your tablet.
[Windows 8 General] Skanob:
Could it be this?

[Windows 8 General] Skanob:
Looks like I'm unlucky on the model that I've got. Take a look:

[IMG="no thermal copper tape"]http://i.imgur.com/PDqFjx2.jpg?1[/IMG]

Note that I have not removed anything from the tablet.

As you can see, the tablet doesn't have any thermal copper tape to absorb heat from the IC's, Processor, and what-not.

Instead what I got is an abomination of aluminum (i think) slab at the back of the back-cover with a white plasticky-rubber to transfer heat, which I think would rather not do the job properly.

Honestly I don't know if this is better or not (I prefer thermal copper tape and thermal paste/glue).

Can anyone upload their thermal copper tape with size/measurement on it, as a reference? I don't want to just put copper tape on it as I know I will short the motherboard. I just want to know the measurement and things needed to include and not on the copper tape, and make it look official-like.
[Windows 8 General] TehMajoo:
Hi everyone!

Finally I got my voyo with dual boot. Thanks for helped me.

Anyone know how to root android in this tablet?

Thanks

EDIT: Play Store doesnt work, it needs internet to connect however Im connected.

Have you tried to install win 8.1 pro x64 yet by the way?
[Windows 8 General] Skanob:
Tried booting windows x64 installer via usb thru usb hub and mice and keyboard. Tried it with booting by Power + Vol UP + Vol Down, then pressing f7 to access boot menu. Just gives me BSOD even before showing anything, past blue windows icon.

How can I know if I'm booted using 64-bit uefi? Any signs?

Edit: fixing usb installer for x86
[Windows 8 General] paul89rulez:
i did it!
[Windows 8 General] Milardo:
When I hold vol + and vol - down at same time then press and hold power button until the tablet powers up and the little white light near the power button on screen lights up you should see that it says switching to android mode or so and if your bios says under the bom/os settings that its in android mode instead of win 8.1, it should be in 64 bit uefi.
[Windows 8 General] Skanob:
I don't know what I'm doing wrong. Do you get the same thing too?

Windows 8.1 Pro x86 installation results:

- I was able to install x86 Pro no problem

- Installed latest drivers, except for DPTF which latest version gives an error-

- My tablet has the OV2680 camera for both back and front, had to look for it over the interwebs and managed to find one. Problem was now I can only use front facing cam, but drivers was installed for both front and back. Camera Metro app cannot switch.

- Left it last night at around %42~%45 charge, woke up to %35~%37 left on battery (after 6 hours sleep). It did not lock up, no deel sleep issues. Note that this is having Wi-Fi ON (but not connected), BT OFF, Location services OFF, all settings changed to maximum battery on OS.

Initially had issues with the tablet itself upon receiving:

[Windows 8 General] Milardo:
I didn't get a bsod but and error with a non smily face and wont get past that, it says when upgrading that the upgrade wasnt successful and rolled back to win 8 x64. Mine doesn't charge via micro usb, how does yours do that, i have z3735f version single boot originally.

[Windows 8 General] Skanob:
Crap! I might have stuffed up the tablet.

I was playing around trying to install Windows 64-bit, now it just doesn't show up the display.

I have found differences between 32-bit uefi to 64-bit uefi, in my tablet on this case:

OS/BOM [32-Bit Windows 8.X/BOM3.1] [64-Bit Android/BOM2.0]

ISP PCI Device Selection [32-bit ISP PCI Devce as B0D2F0] [64-bit ISP PCI Devce as B0D3F0]

DPTF [32-bit Enabled] [64-bit Disabled]

fTPM [32-bit Enabled] [64-bit Disabled]

PAVC [32-bit LITE Mode] [64-bit SERPENT Mode]

LPSS PMW #2 Support [32-bit Disabled] [64-bit Enable]

USB OTG Support [32-bit-bit Disabled] [64-bit PCI Mode]

USB vBUS [32-bit ON] [64-bit OFF]

I have changed them accordingly to the 32-bit settings, but now it doesn't "display". The reason I say display is the that USB hub that I've got have a LED light when it is ON and plugged in. That is how I know if the tablet is ON, but display is off. So LED goes ON on the hub but now no display. I hope its just the display that is the problem.

Edit:

CRAP! Tried booting my Windows 8.1 PRO x86 (installed already) from the 64-bit UEFI and I now it doesn't turn on. FFFFFFFFffffffffffffffff.
[Windows 8 General] jockyw2001:
I thought I bricked mine some days ago, later it turned out the batt was empty.

PS: I also used a hub with a led that was still on, but the led on the tablet didn't go on. Put it on charge for the next few hr

Btw, what are the version numbers of your main and daughter boards?
[Windows 8 General] Skanob:
I thought it was out. Fortunately it woke up. Prolly just empty battery too. I might not worry about 64-bit anymore (unless someone will be able to do it), for the meantime. No real advantage really.

Looking at doing my own wimboot of my installation.

I haven't really had a look on what my boards are. Will do after it finishes charging.
[Windows 8 General] PsyCLown89:
So I got my tablet yesterday, I have the D version. Really nifty tablet, amazing for the price I paid!

Seems as if I won't be able to dualboot the D version? I'd really like to get Android running on it :(
[Windows 8 General] Skanob:
Motherboard is EM_I8080_V6.0

Daughterboard is EM_I8080_3GMODULE_V3.1

Mine is not SIM card ready, non-3G version. What's yours?

Seems I'm pretty lucky to have micro usb charging.
[Windows 8 General] jockyw2001:
My motherboard is 6.1 and 3G module 3.1 and also the non-3G version. Did you inspect the 3G module? Is there only the SIM slot missing? Is yours charging both in 32-bit and 64-bit? Are you charging with a powered hub via OTG cable?
