Well, some of you might have had the same urge to buy one of these little wonder with almost the same data sheet than a LG G2 but with a Dual SIM functionality and at a much smaller price. If you are one of these crazy people that ordered their in China just like me, you might have the same disappointment that I felt when I finally received mine: the advertised SD Card slot is just a fantasy and all Google apps have been replaced by their Baidu counterparts. If the English language is indeed present in the Operating System, none of the installed application seems to understand this language. If you just don't speak Chinese just like me, you might end up wondering why on earth you bought a smartphone destined to Chinese people.
So I decided to turn this frustration into something positive and succeeded so I'm happy to bring you my home cooked ROM for the Lenovo K910. But first of all, the usual disclaimer:
Disclaimer
Don't hold me responsible if you brick your phone. This method have been successfully tested on mine but this is no guarantee for yours. You should obviously always have a backup of your data at all time if you're willing to install this ROM (or any other).
Safety measures
Like most Android phones, the Lenovo Vibe Z have many possibilities of recovery. I would advise you to be ready to apply at least this one:
Download the QSB file of your ROM (for example, mine is K910_SS_S_2_040_0039_131101.qsb). Google will point you to a Baidu site where it is downloadable
Put it in the folder /sdcard/SDFUSE/
Shut down your phone
Hold Volume Down and Power button for a few seconds
You end up in a menu with a "SD Card Update" entry. Move down to this entry using the Volume Down button then press ENTER or power button.
Make sure your ROM is available in the list
Cancel and reboot
If your QSB file is visible in the list, you should be pretty safe. If anything goes wrong, use the same method but apply the upgrade this time. Note that this method overwrite everything included your applications, SD Card, ...
What it is
The ROM I'm offering is:
An extract from K910_SS_S_2_040_0039_131101.qsb
Applying only to your system partition (your applications and data should be safe)
Rooted
Busybox-ed
Grossly freed from most vendor applications
Replaced by Google applications
What it is NOT
This was already some work to figure out how to reach that goal so it is not:
Bug free (I have at least observed a strange display glitch for the network icons which turn standard blue instead of Lenovo's white one)
A multi-language ROM
A ROM build from scratch like MIUI, Cyanogenmod, ...
A custom recovery (though this might come in a later stage)
...
Prerequisite
You should have installed:
K910 ADB Driver (available on the CD that appear when you connect the device)
ADB
Fastboot
Just check that your USB debug mode is enabled (in the USB Access Mode menu).
In any of these prerequisite is an issue for you, I'm ready to explain you further but you should also wonder if you are ready to go further because if anything goes wrong, you won't be able to properly act.
The installation
OK, enough talking, now some action. It is pretty simple actually:
Download the ROM and un-7zip it (mirroring in progress)
Reboot your phone in bootloader mode. Therefore, open a command prompt (no matter which OS you're using) and type:
Code:
adb reboot-bootloader
Now your phone is displaying the Lenovo logo
Check that you can access the system
Code:
fastboot devices
If fastboot just return displaying nothing, you might have to run in Administrator/root mode. Under Linux, I had to use sudo.
Unlock the bootloader (this should wipe all your data if it wasn't unlocked previously):
Code:
fastboot oem unlock
Flash the system:
Code:
fastboot flash system <path-to-file>system.img
Reboot:
Code:
fastboot reboot
That's all folks ! After your phone restarts, you should be able to use Google applications (though not all of them are there, at least the Play Store is allowing you to install the others).
What's next ?
I hope to be able to free some time to achieve these next steps:
Publish the script I wrote to extract content from Lenovo QSB files
Apply the same method to the last upgrade (K910_SS_S_2_040_0078_131203 ?). If you are lucky enough to have this version please contact me to see if you can provide the QSB file.
See if I can cook a custom recovery.
This is probably my very first participation to the community so I'll accept any comments as long as they are constructive :good:
Thanks!!!!!
Thank you so much, I'm crazy because I get the phone and to try, where is the link to download please??
Thanks again, you can post pictures?

Another important question ... How did you rooteado?
What program did you use?
Thanks.
All need you help please.
I'll need just a few more hours since my upload just missed (I'm not sure why it only uploaded 437 Mb on the 659 Mb)
It will be for the first hours of 2014 (at least for me).

Probably in the most complicated way possible: I extracted the system partition from the upgrade file, mounted it in my Linux, put all the needed files and authorization then flashed it on my device.
I confirm that the file is now available but I need a few more messages before I can add the link. In the meanwhile, I can send it privately.

Sure I get it, I also took little time here and leaves add links.
You could pass it private?
With your permission I'll share it on other sites of course directing people to this thread so they can see their creator and comment.
In several HTCMania we are waiting to receive the phone and while we're compiling everything.
Root on many threads where people are wanting to get and so far you're the only one.
I await your email with the link partner, and with your permission I'll share. A greeting.

This means that next upgrade will most probably erase all the content of your phone (again) included your data and internal SD Card. This also means that flashing the first version of my custom ROM will make you "lose" 500 Mb, at least until a release based on the latest version of Lenovo's original ROM.
This also mean that:
Next Custom ROM upgrade won't be applicable to the not upgraded phone (you would be certain of bricking your phone)
You will lost 500 Mb worth of storage on your non expandable device
This isn't all good news ...

They are not good news. but I honestly what I need are 3 things:
1 Language Spanish, but we already you can not imagine not doing anything?
2 Root, to be able to use apps like Titanium Backup, Root Explorer, etc..
3 Very importantly, GAPPS (Play Store, Gmail), but of course in Spanish or English.
Your Rom has 2 I need and it is very important to me and very many users, it is a great job and the first to do so was you.
I do not mind losing 500mb, but I worry that the next official update is dangerous for us.
Thank you very much for sharing the link. If you write more answers in this thread at XDA have permission to put the link publicly, I think the requirement is 10 responses and almost have them.

You control by private (Because here I can not yet) a link to the version you want, I found on google, as I said I have not tested, I hope that this can do wonders lol
I also hope that I root Gapps and either Spanish or English: D

The few post I read about this are telling that it is close to impossible but I installed morelocale 2 on mine and it does add my language in the application that supports it.
Root is probably my top priority so it will stay available in the future releases
Play Store and GMail are present in the ROM and if you install morelocale 2, it will be in Spanish

Of course, the priority is Root.
About the Gapps in Spanish or Englis, the could include a patch?
If not, do not worry that you use MoreLocale2.
I'll try to find more links ... it's a shame it does not work ...
The good news with root access is that you can do a lot of crazy things. For example, I'm starting to understand why it is so hard to get this upgrade thanks to a network dump:
Code:
POST /reaper/server/config2 HTTP/1.1

That said, I'm sick of coming close to the end and receiving a connection time out

If I have latest version K910_SS_S_2_040_0109_131226 installed via ota update and push this system.img from previous version it's ok?

This should work since the system it pretty much self contained but since I haven't tested it, I really can't be sure. Furthermore, this is a downgrade of your system.
If you have this version, could you check if you still have the image on your sdcard? This could be in folder /sdcard/lenovoota.

ok, here's the deal:
1. I tried to push system.img but no working, adb respond "failed: targed locked".
2. I don't have the ota file anymore BUT I have the K910_SS_S_2_040_0109_131226.qsb file. I poot this one in sdfuse folder and updated already before starting procedure with adb from above as you described, no problem just flashed it, btw it wipes everything.
So, my opinions:
1. Locked target issue could be determined by the bootloader beeing locked? Don't we need to unlock it somehow?
2. Can you reinsert root and gapps in this newer version K910_SS_S_2_040_0109_131226.qsb file?
3. How do you decompiled .qsbfile ?
Waiting for your feedback asap.
Respect.
Obs:
- we can use android-aio-flasher just to substitute from working with cmd commands... just sayin', works for me.
- reboot in recovery command doesn't work, just adb reboot bootloader, then lenovo logo appears.
- correct command for pushing system.img is adb fastboot flash system path to system.img.

You are right. I didn't know about android-auto-flasher, probably because I'm running Linux (which made my task easier to cook the ROM since the system partition can be mourned like any other).
I edited my first post with your correction and the link since I have now 10 messages on the board !
Well who are finding out that important things. Hopefully soon have new developments. I keep watching your work. I hope that more and more we are, I have put in all the sites I've found this link for more developers to come.

Originally I tried to create auto CWM for another model Lava Iris x8-L (MTK 6592M) upgraded to V. 5.1 Lollipop and it threw up this copy error. Then I read somewhere that Droid tools v. 2.5.3 doesn't support Lollipop, so i tried it on this Titanium s_10 model with kitkat, and it gave this same error which tells me me that I am doing something wrong. I am using admin account and even running the program as an admin. The drivers are all fine, readback is successful, just the CWM is not being made. If ura1 or someone else can guide me, I would be extremely grateful.
I am new here so before someone tells me to post in the correct thread by ura1, i wish to clarify that upon trying to reply to that thread xda throws up this page saying:

I hope mods can adjust or relocate my thread.

Could someone please help? I don't want to use a random img from internet to avoid problems.
I accidentally hard bricked my tablet trying to unlock the bootloader with fastboot, and now I can't find any stock roms to reflash it. Do any of you have a rom for this tablet (the rct6773w22b, which is different from the rct6773w22)? I have looked all over google and cannot find anything for it. Any help will be greatly appreciated.

Can you make this rom available again, please?
Hi guys,
I bought this tablet at the end of 2016. I played a lot with it, about 2 years. I sold it at the end of 2018.
These days i try to make some space in my hard drive, so i delete some files.
I have downloaded on 2016 many things about this tablet. Even now, Onda's official site is in Chinese and i saw that Onda Forum is down.
So i decided to upload here my experience, some instructions and service files about this tablet.
I will upload the files i have not at once, so before asking questions wait a little.
Enjoy
P.S : Sorry, now i saw that there is a limit on the size of files that a member can upload !! I wanted to upload the Original ROMS of this tablet (they are some GBs !!).
Please put the instructions
Hello,
I appreciate your good will gesture. I am interested in reinstalling the os on such a tablet ( I think mine is v5) and I can't find instructions and files for windows only the V820W_DUALOS_V5_32_1605279_20160602.zip(after windwos 10 reset I can't boot windows ,works only on Android). Hope you will continue, thanks.
Found solution to recover Windows 10 on tablet but lost Android
Hello , after some more search I found an interesting russian forum with many download links for this tablet. Here is a download link that contains many of the necessary files for Onda v820w from there:
........
For my case (tablet was reseted from windows options I presume, and was not able to boot anymore just some automatic repair started but did not work) , making a NTFS bootable disk with rufus and copied all the windows files from 10_V3.rar found in the download link provided and choosing ->"System image recovery"->then something about boot from EFI usb drive I remember. And it worked, it managed to reinstall windows and make it boot again by itself.
After succeeding this I became more confident and tried to update the Android form this tablet from 4.4 to 5 as I saw it has everything we need in the above link. After trying different versions of Manufacturing flash tool and Intel drivers for this tablet I managed to connect to it and make it take the provided image with Android 5 from fastboot menu when connected to laptop with the flash tool.
The only problem is it said it does not have enough space to flash system.img at around 84% on the Manufacturing flash tool loading bar. (strange as the tablet is empty,nothing on it, just default software).
Now Android does not boot anymore (haha, fixed something destroyed something).
The questions are:
-Can and how to use the other Android 5 images I found on the russian forum ? They are different type of backup files (with system.ext4.win type of files not .img files that the manufacturing flash tool expects).
From what I've read they are TWRP generated backups but my tablet has the default recovery.
-Can I convert the TWRP files to .img ?
-I found an TWRP recovery for this tablet (I hope) but I am not sure that if I flash the TWRP recovery it will not mess with the windows partitions already working on this tablet...
Here are the files I found and some english step by step tutorial for flashing the Android and a spanish tutorial for the Windows part of this tablet, on my google drive:

RE: Links to Onda v820w windows files
Hi Olaruci,
I seem to have a similar problem to the one you and POWERSER have had. Please can you assist with the download links for this tablet. I can't boot the tablet into Android or Windows, only the system recovery option is available to me and it doesn't work.
Thanks :good:

Hello , after some more search I found an interesting russian forum with many download links for this tablet. Here is a download link that contains many of the necessary files for Onda v820w from there:
........
For my case (tablet was reseted from windows options I presume, and was not able to boot anymore just some automatic repair started but did not work) , making a NTFS bootable disk with rufus and copied all the windows files from 10_V3.rar found in the download link provided and choosing ->"System image recovery"->then something about boot from EFI usb drive I remember. And it worked, it managed to reinstall windows and make it boot again by itself.
After succeeding this I became more confident and tried to update the Android form this tablet from 4.4 to 5 as I saw it has everything we need in the above link. After trying different versions of Manufacturing flash tool and Intel drivers for this tablet I managed to connect to it and make it take the provided image with Android 5 from fastboot menu when connected to laptop with the flash tool.
The only problem is it said it does not have enough space to flash system.img at around 84% on the Manufacturing flash tool loading bar. (strange as the tablet is empty,nothing on it, just default software).
Now Android does not boot anymore (haha, fixed something destroyed something).
The questions are:
-Can and how to use the other Android 5 images I found on the russian forum ? They are different type of backup files (with system.ext4.win type of files not .img files that the manufacturing flash tool expects).
From what I've read they are TWRP generated backups but my tablet has the default recovery.
-Can I convert the TWRP files to .img ?
-I found an TWRP recovery for this tablet (I hope) but I am not sure that if I flash the TWRP recovery it will not mess with the windows partitions already working on this tablet...
Here are the files I found and some english step by step tutorial for flashing the Android and a spanish tutorial for the Windows part of this tablet, on my google drive:

Download links Onda v820w
Hello Grimm1,
I've sent the download links in private message.
I still did not manage to flash any of the system.img files ( I tried to unzip system.ext4.win images and change extension to .img but it's not working, not valid).
So I've changed the original recovery.img with the TWRP recovery found in the download link, and it works.
Now I have TWRP but with a small problem, it's in russian... now I try to find a way to change language (it's the materialized theme of TWRP 2.8 , and it seems it does't have a change language option)
Also windows 10 on PC needs latest versions of:
- Manufacturing flash tool (6.051)
- IntelAndroidDrvSetup1.10.0
- iSocUSB-Driver-Setup-1.0.4 or 1.0.5 (I THINK THIS IS THE MOST IMPORTANT to have latest version FOR THE MANUFACTURING FLASH TOOL TO SEE THE TABLET)
Also only connect tablet to laptop usb(in fastboot mode) AFTER opening manufacturing flash tool and AFTER selecting xml file and message "ready to flash" appears.
Hi,
I'm using an Onda v820w dual OS. I like this tablet and its dual OS capability.
I'm trying for days to find a way to change a few things but ondaforum is down so it's not easy now.
Once I succede I will give links and steps.
A first link where there is a lot to download : http://chinagadgetsreviews.blogspot.com/search?q=v820w&x=0&y=0
/!\ WARNING /!\ I did not test any of the software found on the link above so don't blame me if it screw your devices.
The first step was to install TWRP to be able to flash Android 5 instead of 4.4. The one I use is in russian for the moment so I use Google translate...
Anyway I just flashed Android 5.1 found on a russian forum a few minutes ago. For the moment the tablet is on the boot anim for at least 20mn...
I will tell you.

Hi Olaruci, thanks for the link it was a lifesaver for me
I only stumbled to one problem - for some reason I can not calibrate my Touchscreen. It works, but nither the Touch PG or MS Calibration software helped me...the calibration is just off (few cm gap). Did anyone had this kind of problem and what do you think I could do to solve this problem?
Kind regards to everyone who contributed this feed....it helped a lot.
