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.

Hello,
Running i9250 on stock 4.2 android.
Want to try the Ubuntu stable build on it. I can see the Ubuntu Installation steps on Ubuntu website.
However just want to know what would be the way back to android. Would I be able to keep CWM recovery partition and restore an old nandroid backup. ?
Secondly is it possible to run Android and Ubuntu in a dual boot mode..
Thanks for your replies.

Hello,
at least for 2012 Sony Xperias (S, Acro S and ION) there exists a dual boot tool by @letama, which can be found here and is verified to run the Ubuntu OS as one of the two roms (or both, whatever sense that should make...).
Of course this specific minikernel will not help you directly, but maybe it'll point you in the right direction to continue your search. Maybe you can find out, whether a similar tool can be made / exists for your device in the thread mentioned.

I installed the stable version on my I9250. I'm not sure about the dual boot as this was not my daily driver.
From my experience after installing I could not go back to a CWM ot TWRP back up.
I had to do a reinstall a fresh 4.2.2 and then re-root.
I tried to restore back up from TWRP, but for some reason I had issues with a complete restore.
it was no biggie for me, since it was not my daily driver, but I made sure to back up the data I had on it just in case.
My experience.
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....

As title says, I'm looking for the Windows 10 Drivers for the Ployer Momo8W Dual Boot Tablet.
While updating the Windows 10 version of my tablet an error occured during the installation of the new version. I managed to do a clean install of windows 10 from an USB stick but now I have several "unknown devices" in the device manager, the touch display doesn't respond and screen rotation doesn't work either (everything is upside down as in 180° distorted)
I have found a thread with Ployer Momo7w drivers here on xda, but I'm not sure if they would work on my momo8w though. I hope someone can help me.
Hey buddy.
I'm going through similar with my Momo9w, while playing around trying to make it dual boot I messed it up, removed recovery to accidentally.
Finally managed to get a clean install of Windows 10 on it, then had another go today and now need to go through it all again! Worth a go.
Anyway I wanted to say the Momo7w drivers posted seem to work with my 9W, so I'm sure they will with your 8w.
The only issue I had on win 10 was the touch screen calibration not working right, the touch point was off from where I was touching it. However there is a Chuwi topic on here I've jist been reading with similar problems and fixes, so when I am back to win 10 I will try those.

Hey Buddy.
Ah, I'm still struggling to be honest.
Originally I installed Windows 8.1 and got the touch screen working fine after a few tries, then it updated to Windows 10 and there was no problem. Then in my stupidity I tried installing a dual boot with Android again and now I'm back to the beginning with Win 8.1 beside me and trying to fix the calibration again!
From the time before it is something to do with the touch screen driver and the Windows driver it installs for the screen, I've read the touch drivers need to be installed after in this case.
I'm currently sat beside the tablet trying to get the touch screen working on Win 8.1 again.
Ian
Thx for the tip with the chuwi thread, managed to install the touch screen drivers and it's now working again
I hope you can solve that problem of yours too
Hi all. Ehhh... Not very closely related, but you guys here appear to be the best experts on the topic on the whole wide internet, so I hope you can help me out.
Just bought a Ployer momo8w dual boot for my daughter, but the accelerometer won't work in Android.
My unit came with a new firmware, Android 5.1.1 and Windows 10. The accelerometer does work in W10, but would not even show up in Cpu-z or sensorbox in Android. Is there any way to 'hack it', or any way to downgrade the firmware to Android 4.4/W8.1 or whatever exact version these used to be shipped with? I could not even google anyone else having this problem, but I have two devices (two daughters) and they both have this issue.
ME TOO HOW INSTALL win10 driver ?
I do a backup using powershell like i found around here... and uploaded to mega.
Here's the link:
Drivers:
hXXps://mega.nz/#!SsdVnSjJ!XPHRqwMmOHVye7XxVoD1qdu95jy7bkV_5BVBBDR-rVE
And for a touchscreen 100% working you need to copy SileadTouch.fw to System32\Drivers folder and reboot.
SileadTouch:
hXXps://mega.nz/#!qgdBhSwS!pF0y7NfyC6UHVIGgDFfcwdnTemya7wUZe4Dt_o2htC0
And for fully working Video, i used Intel Driver Update Utility, downloaded from intel's site, here:
hXXXs://downloadcenter.intel.com/download/25977/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-33-
but you can download the driver from here:
XxXxs://mega.nz/#!W5NUTYZI!sBaGoJhJl0NZvALsBpCMOmvgqdIOTvOVJwabioVBIdc
The only thing that it's not working for me i'ts the mSD Card Reader
i downloaded the first link, but which folder do i put it in? please help im struggeling with the touch
I know this thread is quite old... but I managed to get some drivers at least.
For Bluetooth you can download the official Realtek drivers here:
realtek.com/en/component/zoo/category/rtl8723bs-software
For audio I found this (lenovo website):
support.lenovo.com/us/en/downloads/ds040044
But for touch I still have no clue! The SileadTouch file didn´t work for me.
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
Best
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?
http://support.lenovo.com/de/de/products/Tablets/Yoga-Series/YOGA-Book/downloads/DS119182
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...
