Android to Windows Hack or Dual boot Option? - Lenovo Yoga Book Questions & Answers

So im thinking of purchasing one of these when the come out here and i was wondering about an android to windows os hack. Will there be one in the immediate future and will dual booting be an option?

The hardware is exactly the same.
There must be a way to dual boot, hopefully others on this forum can figure out how to do this if Lenovo doesn't facilitate dual boot themselves

I believe there's a different BIOS for Win vs Android. Could have sworn I saw the Windows BIOS posted on the Lenovo support site prior to the Oct 17 launch. It seems gone now though, unless I'm missing something or went to the wrong link? Unlikely you can install Win without a different BIOS.

There is some clear hardware differences with the Android and Windows tablets. Specifically, 2 different physical layouts for the halo keyboard, where the windows one has defined left and right mouse click buttons. There doesn't seem to be any way of accessing the BIOS on the Android tablet, and it does have the usual Android power + volume up, power + volume down recovery options, so it looks like it boot directly to the boot loader.

The Bios is still there ... but how would you flash it?

ok so there is also android open source code available in their site, any chance of making a custom rom?

I wonder if we could flash the Chuwi 12 roms onto this given that Chuwi12 has dual boot already?
This is reallly really stupid to me, why not provide dual boot in the first place? I would not mind shelling out $100 more for a dual boot version. Now if I want the windows version I will need to spend another $550 to get another OS with the same device. I will end up having 2 same devices, but that is so anti-mobile really. Do I have to carry 2 hardware devices so i can have 2 OSes at the same time?
Lenovo get some grip please and provide a dual OS version.

win 10 driver
Today, the windos 10 drivers are online..
The drivers you get with levono support with input of the serial number
It must now be possible to build a dual system
Tastertur chipset audio and more .

Could you post the link for the windows 10 drivers? also any idea on how to unlock the bootloader?

Hi,
earthCallingAngela did unlock the bootlader. .
My background knowledge about booting is very low. But I think there are huge differences between Android and Windows. I think If a system can boot via PC-Bios or Android-Boot-Loader is "on the chip". If this is correct you would need a Android-Boot-Loader that does boot into a windows ... IMO this is no "easy to do". May be the guys who did create Remix OS found a way to do that ...?

Can we use Chuwi 12's disk image somehow? It comes with dual boot.

Are the two the same hardware? My understanding is that unless the hardware is very similar, you can't use other ROMs without a *TON* of work.

so i was able to install android x86 6.0 on my yoga book, unfortunately i managed to do it over my windows install so now i just need to reinstall windows lol.....

Hi & Happy New Year
Now it's possible to get root with android version
I have a YogaBook with Windows version ; Someone can make a backup Android version?
Maybe it's possible to create a dual boot with the windows version I cross the fingers :fingers-crossed:

Where and how?

someone can said me, where i found an android image? (original yoga book, of course) i try to install Remix OS and Android-x86 6.0-r1 released from Android-x86.org but, its can't run. graphics issues and reboot.
i install in a MicroSD and boot it booting yogabook hold volume up + power boton and select boot menu, but it fail on boot.
i have yoga book windows. any idea?
thanks
sorry for my english..

I'm exploring this as well.
Since the BIOS and drivers available (just tested with my serial#), it does seem like it would be relatively easy to dual-boot, provided you can get past the loader issue.
I've done many dual-boot setups, just not since the Win7 days, with the Win8 and forward it's gotten quite a bit trickier, the loader does a bunch of "extra" stuff, boot timing and such, to protect itself.
I've also never done an Android/Windows dual-boot, mostly just Win/Win or Win/Unix.
I think you'd have to figure out how to bootstrap these, so the custom loader can take over, and load from there, but this is a bit beyond my Android capabilities.
Has anyone even tried this? I assume the power/volume keys must work, to get at the loader?

Hi there !
I've just unlocked my Yoga Book's android bootloader and made a backup. I'm trying to install Windows 10 and replace Android with it. The problem is that I don't know how to boot the device from the USB drive.
Does anyone know how to do that ? Even if rooting is required ?
P.S. : I can't google it as all results link to "how to boot a PC from android device", which is the reverse...

how comparable is 2.3.1 and 2.3.3 and how similar would the cwm be? I ask because I have a cheap dopo md-702 tablet that I would like to try working with. It has 2.3.1 and I was wondering how to get cwm to work with the tablet. It has a rockchip rk2918 so any ideas on where to start digging?

Most cheap tablets cannot have cwm due to the lack of recovery menu. Cheap tablets are already rooted. Just install superuser and do whatever you want with. But once again. Due to lack of recovery you have to be careful with what you do.

In a very interesting sort of way the tablet has a recovery mode but it takes multiple steps to get to it. The long and short I used quick boot app to boot to recovery (which looked similar to a download mode) and then had to try different key presses to get into the actual recovery mode. I can run an update.zip from the menu but nothing else. It looks so similar to what the modded cwm is for our phones that I wonder if there was a way to look at the codes and compare. Also note worthy after I used Titanium Backup to unistall the phone (bad idea) I had to hit the reset button to see if I could start it back up, and it booted back to just the basic apps but still had the google play app (this tablet did not come with google play originally). There are just so many little nuances that I'm not sure what is going on with this tablet. I need to have some time to connect it to my PC so I can see if there is a way to look at the tablet through the computer similar to what I used to do with my windows phone.
There is also an upgraded model of the tablet that has 4.0, with a 1.2Ghz instead of 1Ghz processor. Is the OS (android 4.0) a part of the firmware? If I have the firmware from the newer model what are the chances it would work with the older model?
I want to copy this post over to the tablet thread and hopefully get some hits over there.

As long as you have a way to get to recovery from boot up you shouldn't have much of a problem. And Android and Windows work differently on many things. But android is more open. *you can do whatever with it* and if I'm not mistaken you can upgrade your firmware to 4.0 through recovery. Some tablets you can upgrade by downloading the firmware on the tablet's site.. Try that if it doesn't have the option to do a system update in the settings.
Right now I'm bricked, used the firmware from the upgraded model but worried that because there a gig of additional memory, but the rest of the hardware specs are identical, so right will not boot. Fuzzy lines, going to try and drain battery then charge and boot into recovery.
Let me clarify, I used the firmware from the manufacturer for the upgraded model. So I thought out would work. I've not given up but not optimistic. If I'm lucky someone can pull the original firmware and I can miraculously get it into download mode again for a reflash, that is if I can't get a factory reset.
UPDATE: I can power on to the first animation, the infamous penguin. Going to see if either computer will notice it tomorrow. If neither will, I'm not sure I can do any thing more.
UPDATE: it will connect but windows doesn't recognize it. I'm thinking I have options but will take time.

The image ver. is acer_av041_a500_1.33.00_pa_cus1. I have tried one of the rooting options here and it did not root my device, . I can not find it now for some reason. any ways mainly I am trying to find out, is my rom on my tablet a stock version? can someone point me to a rooter that will unlock it thanks so much for any help.
the gingerbreak v1.20 apk is what i tried and it did not work.
first off i am not finding my version of rom listed any were in the official acer list. acer_av041_a500_1.33.00_pa_cus1 could acers ota of locked my tablet making me lose root but not flash their rom to my table?

Acer bootloaders have always been locked. Anybody wants to argue?
Now, first off, we need to know what version OS you are on.
If you are on ICS, with an ICS bootloader (give the version please) then there is no full root available unless you install the V8 bootloader from skrilax_cz.
Root involves full system RW. Not the half-root people promise.

First off thanks so much for the reply, i thought the boot loader was locked but was hopping it wasn't. First the tablet is working and this is the information i get off it.
adrodi version 4.0.3
image version
acer_av041_a500_rv16rb02_ww_gen1
build number
acer_av041_a500_0.009.00_ww_gen1
some of the problem i have had with some root methods is the fact that my only laptop i have right now has windows 8.1, and a lot of this stuff pre-dates windows 8, that and i am not really failure with 8 yet. I was able to disable the apc controls i think it was called, i was needing to disable it because this one script needed it disabled to try and root my tablet. But then i had a driver issue were windows 8 would not see the tablet.
another thing do not know if this matters or not but under image P/N it say unknown.
hmm, found some information i could not find before. according to another web site i do have an official os and that i am on ics. Still trying to find out why image p/n is unknown, and how to root.

And you are right. Most of the stuff pre-dates win8. However, NVFlash doesn't matter.
I would prefer you do this under a Win7 machine if you can find one.
the only windows 7 machine i have access too right now is at work, and they have the dang thing locked up tighter then a drum. I am going on vacation at the end of the week, when i get back plan on getting windows 7 and putting it on the laptop. I have xp but the laptop is a 64bit system. Main thing for me is i get the information, everything i find i save it to my drop box account for now.

I'd give the babsector file a try on yr xp laptop, you never know it may do the trick....
The gingerbreak root file u tried is for gingerbread builds so try icsRoot altho it may not work with win8
If the updat.zip definitely don't work then you have to have the cpuid. Have u had the tab connected to the pc previous to your tabs troubles??? Usbdeview will retrieve the cpuid in this instance. You can d/l it from the cpuid guide. Also check the root guide in my Sig, a lot of useful files u need you can get from there.
Good luck and to @Moscow Desire a big, helllllooooo and kiwi hug 4 u too my friend and yes like u , I'm still lurking about the place

Sorry wrong info, I jumped the gun. :silly:
Anywho, have you tried using virtual machine allowing full access to host PC, then either windows or Linux?
You could also try a liveCD.
That is if you like the windows 8's. Change to 7, set your BIOS correctly and watch partitions don't get screwy. I just had to install 7 the other day. The partitions got messed, so erased everything with gparted. Went into BIOS checked safe boot settings, wiped the key so it would reset user back to setup. Then started install without a hitch.
Hope that helps.

Install Android 4.4 on Toshiba Encore 2 (WT8-B)

Hi everyone,
So a few days ago I bought a Toshiba Encore 2 and Windows 8 is just not what I'm looking for in a tablet.
I've looked into Thatgrass' guide on how to dualboot Windows 8/Android but it's somewhat outdated to the machines in the market (atleast Toshiba's)
(Link to the guide: http://forum.xda-developers.com/showthread.php?t=2321292)
I'm stuck at the boot step:
I hold the Power and Vol+ keys in order to select the device I want to boot from and once I click in the USB, which is recognized, it jumps to Toshiba's boot screen and starts loading Windows 8. (Well, since secure boot is disabled it actually goes to BitLocker)
Any thoughts? Steps I might be missing?
Has anyone successfully installed Android in this particular machine?
Thanks.

Android-IA or Windows/Android dual boot tablet

I have spent about a week now trying to figure out if it's possible to boot Android-IA on a 32 bit UEFI system. I have seen threads on the mailing list and other sites that apparently have gotten it working on the T100TA, but the links to their compiled roms are dead. I specifically am looking at doing this on an HP Stream 7 and making a dual boot car install. Has anyone successfully booted Android-IA on 32bit UEFI?
If this is not possible, how do the Chinese tablet manufactures do it with the same Atom chipset? I need a 7" tablet that can dual boot Android and Windows. Is there any quality model I should look for? I have seen the Cube iWork 7 which looks promising, and seems to be perfect for my needs. I will need root in Android for the car install.
I've been a lurker on these forums for a while, but just now got around to making an account. Hopefully someone here can share their experiences or suggestions. Thank you all
May be it's too late to reply, but anyway.
iWork 7 DualOS BIOS has both UEFI64 and UEFI32 booting. If you load Android(i.e. Linux), then 64bit mode is using. If you boot Windows, then 32bit mode is using.

Probably, your backup isn't full, i.e., not all partitions are backed up. TWRP sees only standard partitions like boot, data, system. But there are many service partitions. For example, on my iWork7 there are 17(!) partitions used solely by Android.
So, i think, after downgrading you've got mess of old and new versions of partitions and they are not compatible to each other.
So, you need initial Android installer (like my iWork7 has). Contact Lenovo support.

I have recovered from this mayhem, i had to flash official firmware but now I am in another difficult situation.
After updating to lollipop, I am facing a weird 'sim not ready' error, no mobile netrwork appears nor the setting of mobile network is configurable, no data(2g,3g,4g) no voice call support.
When i insert sim card it shows sim added notification, also telecom stk app shows that sim has been read,
but still I am unable to figure it out why the goddamn network doesnot shows up? Btw wifi is working nice.
Is any body also facing same issue? What causes this error?Any help to resolve this will be much appreciated.*
P.S. I am in good network and I have also tried different sim cards but no luck so far....

[Q] Rikomagic V5 (mk802V) Dual boot or ROM work

Is any one working on or been successful in getting one of these devices Rikomagic mk802V V5 (RK3288) HDMI stick to dual boot with Linux and Android OR succeeded in backing up the ROM it ships with?
I have the android version and would like to dual boot it to Linux. I have looked at work done by lunuxium and others, however the methods used require a Linux PC. I have many versions of the Flashtool software for windows from version 1.3 through to 2.3. I have the factory flash tool as well and several images to replace the boot sector of the device. Not sure if boot sector is correct terminology.
While the device is detected by some of the software when I turn on USB debugging and Connect to PC via the OTG USB port, however the software reports a device mismatch and halts when I try to do something. All versions I have tried do this.
I'm also a bit lost on the instructions that I have read that do apply for windows. I might not be succeeding because of this. So my questions for anyone who has succeeded:
Does anyone have a software application that actually does succeed to write to a rk3288 chip device?
Do the boot img files by linuxium work as is or do they need to be injected into a device ROM to be flashed onto the device?
Is the correct way to flash it to just use the boot img or the whole ROM?
Do I need to download the original ROM and modify that to make it work?
How can I download the original ROM from the device so I have a backup?
Does the device need to be in recovery mode or is it acceptable to boot it with USB debugging?
If anyone can help I'd really appreciate it.
thanks
303.
Looks like a workable solution has been found. Taking a bit of time and reading through linuxiums' web page on Latest news for RK3288's here:
sitesDOTgoogleDOTcom/site/ianwmorrison/Downhome/Topic6
The above link contains instructions for several different methods of dual booting an rk3288
Looking at the section: Simplified dual boot Android and Ubuntu Utopic Unicorn 14.10
I followed those instructions and it was straight forward.
There are several bootable images linked on that page. I think they are the same image but they might not be. I ended up with an Ubuntu image although I don't recognize the desktop.
At this time the ethernet network does not work. It is configurable but not working. I will look at the images and see if there is some different ones there to try.
