Hello everyone,
I bought this tablet on ebay and it seems that the ROM preinstalled is a test ROM.
I searched the web to find a custom ROM but I couldn't find much info.
I found the way to root the tablet but that's all.
Is there anyone who can indicate me a link to a stock rom or a good custom one?
Thanks for those who will read and help!
What do you mean by TEST ROM?!!! this is ridiculous, I have the tablet and it's working like a charm even I received over air update yesterday, the only odd is that I can't use it as a phone because Lenovo has no license yet for that it's available only in the Chinese version, and I think this will be solved later when they start launching their mobile phones all over the world.
Hello mmis,
Test rom is not the correct terms but I didn't know how to call that !
The problem is that every widget I put on the desktop is loading but never display anything.
The information in "About tablet" are the following :
Model number : IdeaTab A2107A-H
Android Version : 4.0.3
Baseband version : MAUI.11AMD.W11.50.SP.V13, 2012/05/25 01:09
Build number : A2107A-H_S307_120605
If I search for system updates, it doesn't find anything. If I click on firmware update, the settings FC.
I made a factory reset but no luck.
That's why I thought it wasn't a stable version.
As long as you tried the factory reset with no luck, I think in your case its better to get back to Lenovo customer service or your local dealer if it's under warranty, they should be able to help you. it's a new device in the market and it will be difficult to find custom ROM for a while or even someone to give model-specific help. Good Luck
Would you mind linking to the instructions on how to root this thing?
Sure, no problem !
After several hours of search and difficulties to register onto Chinese websites
I managed to find the attached file. I take no credit for the tool because it was developped by someone else (SNARL I guess)
It was missing the superuser apk inside so I put it back and also translate the steps to English.
Here are the steps :
- Connect the tablet in Debug USB mode
- Launch root.bat
- The device will reboot at each of the 3 steps
If you need more info, don't mind to ask!
Here is the link of the original thread :

Fantastic, thank you very much.
LePad Chinese Model A2107A-H
I have a Chinese issue model of the A2107A-H that has the dual sim card cellular feature. I've been trying to get it rooted to get rid of the Chinese apks on it, but normal rooting software has not been successful so far, including the one posted here from SNARL via Ichi go's post. I get a "device not found" error message and in device manager on my PC it indicates that there is no driver installed for the device. I have "debug" turned on and the USB link seems to be working as I can see file folders on the device, but the rooting software will not run. I've tried several of the most well known methods with no luck. Any ideas on this would be appreciated and in particular, if there is a driver I need to have installed to get the rooting software to work??
TIA!!!
Rob
First of all many thanks to you ichi go it was very easy to root this device as instructed, but as the one I have does not have the phone calling capability, I replaced the phone.apk with different one but now the device does not recognize the sim card at all, I tried to push many versions of phone.apk to system folder with no luck, it seems even if I put the apk in the system folder the device will not launch it at all, could you please help me in that.
I've had this tablet for a while and love it. I just got the OTA update and its downloading now.
I'm a also keen on rooting it and inns installing a custom ROM. I guess once its a bit more common, we can expect a dedicated Dev community here on XDA
The update failed to install. I'm not rooted or anything but upon restart it gave a signature verification error.
Any way to fix this?
Edit: got it! was a path error since i had changed the default storage.
but i can't figure out any changes

How does your device appear in the device manager? For sure, the adb driver isn't installed. If it's not the case, download android sdk and then the Google USB driver in the extra section.

FM Tuner - perfect for in-dash?
The in-dash car tablet people should be happy to hear the A2107 has an FM Tuner. It's one of the few tablets that has a radio tuner, and the only modern 7" that I know of. I just ordered one. I will report back.
The Chinese stock rom I installed has the phone ability and that works very well! The problem of this stock rom is that the Google services aren't there. I'm trying to find a way to install the zip file but I need to know the exact path of the recovery partition.
I tried to find it with the cat /proc/emmc command but this partition isn't listed.
If anyone has an idea...

So I understood that you managed to flash the Chinese stock ROM, am I right?!! please tell me how to do as I am facing serious problems with my device, I managed to root and then I changed the phone.apk (what the hell I was thinking of) and now I have the the error message android.process.acore stopped working and sometimes the sittings force closed, I tried to re root, factory reset and deleting cache of almost everything with no use, even I contacted the Lenovo CS to reinstall the original firmware, I think they will charge me for that :crying:
by the way I don't have contacts anymore (I installed it manually) and the most impressive thing that the device doesn't recognize the SIM card (I cleverly deleted the original one phone.apk :silly and what ever apk I push into the system/app folder and change the permissions it will not install after reboot.
So...what do you think guys?!! any help?
I've confirmed this does work on the A2107-F.
I had some trouble with the ADB driver. I can't post links, so you will have to google it, but I used adb_driver_20110720.zip for the drivers. I forced it to install via Update Driver > Browse my computer > let me pick > have disk > pointed to the android_winusb.inf file > selected the thinkpad option, it was the bottom of the two.
I also had to manually turn the tablet back on after the first reboot, but it went fine after that.

Hi mmis,
I will upload tonight (if i have the time to) all the needed files to install the Chinese ROM (tools and procedure included).
Btw, I managed to install all the Google services and all is working well! The only thing is that the OS can only be put in English. All other languages are Chinese variants.
Hi I just flash tablet with a chinesse rom A2107A_H_S121_120525 and right now the device don't turning on anymore. The flashing is still possible. So I need a stock rom please
Hi
I am new to hacking android. I have built linux distros in the past, and have worked with Linux for 15 years,
I have just rooted a ZTE V965. It doesn't come pre-installed with Play store, and has all sorts of ZTE-specific Chinese apps. It has a good baseband circuit, a good screen, reasonable camera and I think is a great value phone, apart from the awful UI.
It is an android phone, although heavily customised. It has an MTK6589 processor coupled with 4Gb ROM and 512Mb RAM.
I have other phones which operate a much more "Vanilla" android. For example, the Guophone 9105 which also uses an MTK6589. This has a troubling tendency to reboot every random interval. Approx 6 times a week.
I have had success in the past running Linux systems built for much earlier kernels on later kernels. This suggests the ABI (application binary interface) for the Linux kernel changes rather slowly.
I am wondering how well the userland apps are separated from the kernel and drivers on Android.
Specifically, is it feasible to dump all the UI stuff from one phone onto another then change the init to launch the other UI?
Would this risk bricking the phone, or would the shell commands and ADB infrastructure still likely operate?
I guess I should change the bootloader to one that supports fastboot first, right? Is ther a how-to on achieveing this from the root shell?
Thanks for any thoughts
Nick.

Hi Nick, I have the same phone. I'm also very new to android, last phone was iOS and before that windows. I managed to root the V965 using Vroot. I also managed to install SuperSU and CWM. However, the CWM is not fully functional, I can only do a factory reset, not install any packages or roms. Probably the phone has a locked bootloader. I can't check, because the USB driver with the phone doesnt support fastboot.
I really need to get google play working in this phone, read a lot of stuff, tried many things, but I havent succeeded yet. Please let me know if you make any progress.
In China they are flashing this phone, found some ROMs even, but I am not sure how they manage and google translate isn't much help there.

Hmmm my V965 is having some issues now
After a factory reset, the setup wizard keeps crashing. Even after another resest. So I can't get in the phone anymore.
Any chance you can send me the USB drivers that are on the phone? My phone isnt deteceted anymore, so I can't access the drivers, which I want to reinstall. And of course they are not on the ZTE website.

Fastboot and ADB appear to be standard protocols, at least on my Ubuntu, which don't need special drivers. However, it does appear that the stock boot loaader on the v965 does fail to incorporate the fastboot option.
If you remove the battery, replace it then turn on holding the volume down, you will get a menu, but fastboot is not there.
I don't know for a fact, but I do suspect that if you have access to the running android system as root, then you could in principle change any of the internal flash data. Therefore, in principle, I guess you could replace the boot loader or anything else in the running android system. Anyone please correct me if I am wrong, or confirm if I am right.
The feature set of this phone seems to be the same as the feature set of my Guophone. MTK6589, dual SIM, etc. So this image may be a good place to start if considering a transplant.
If you have ROMs, then perhaps it is possible to flash the ROM from a root terminal. I'm thinking add the uncompressed ROM to the Micro SD card, then using the dd command, block copy it to the appropriate image area on the internal ROM, reboot, reset to factory defaults.
If anyone more experienced than me with the nuts and bolts of Android can confirm or deny this will work, or where it should be put, please let me know.
An important factor is that the NAND is not locked on the ZTE V965. So if you have a root shell on the phone, you can issue the following command:
mount -o remount,rw /[email protected] /system/
Once you have done this, you will have read/write access to the system partition.
The only thing I then need to know is what should I avoid changing that may break the ADB bridge/root console?
And is all the UI stuff kept together, if so, where?
Shuffle it around a bit, make a new ROM
Thanks for the driver!
Unfortuntely it doesn't help
I found out the culprit, I tried to install gapps (google apps package) to the system app folder. I thought these changes would be reversed with a factory reset, but they are not. Setupwizard.apk keeps crashing and is preventing me from accessing my phone, so I must find a way to remove it from the system app folder. However, since this error occurred, I am not able to contact the phone in any way from the PC. Adb toolkit does not detect it, even when I reinstalled your driver. It's quite puzzling, I dont understand why in recovery mode I cannot connect adb-toolkit anymore.
Got my V965 working again, but it was a lot of hassle with shell access. Still not fully functional, no drives detected when i connect to USB, which is quite annoying, but not more than that. If you ever make any progress with google apps or flashing, please keep me informed, that would make this phone much more useable. I'll also keep hacking away at it, but without a bootloader unlock (I still think this is the problem), I don't think it will be possible.
I'm convinced it's possible to flash the phone, it seems they do it a lot in China.
I found a website with a couple of custom ROMs specific for the V965:
http://www.romjd.com/Rom/Detail/17086
And what I suspect is a rooting & flashing tool. Rooting works, I haven't figured out flashing yet.
http://dl.vmall.com/c0xa12brvo
I've also tried flashing from the settings - update menu in the phone, but it never finds the ROM (update.zip)
I did find another problem, I can't be reached on my phone, it always goes to voicemail. Same SIM in another phone works fine. No idea what's causing this.

Hi
I might be able to help you with the problem.
I have a mint, unused ZTE v965. I have used MTK Droid root and tools to extract a backup of the entire new phone. It is currently uploading to www dot nickhill dot co dot uk forward slash ZTE-V965_new_backup.zip
You should be able to write this back to your phone using flashtool.exe.
I don't know for sure if this will work, so entirely at your own risk! Just trying to help. If unsure, ask around.
I am new to this forum, so please remember to click the thanks button if you find anything I have done helpful!
Meanwhile, the MTK droid root and tools has a function to remove much of the chinese stuff (once the system has been installed) and there is always the cyanogenmod gapps package. This may be worth investigating.

Thanks for the ROM, i'll give it a go. I will try to install it using the update option in the settings, that seems the safest.
Be careful with gapps. setupwizard.apk + factory reset = a lot of problems (if you install in system app folder)
OMG that tool is awesome. created CWM boot, installed your ROM, then installed a clean ROM, then installed gapps, all working!!!

Firstly, I'm glad it's working for you.
Secondly, which tools did you use? Did you unpack the zip, open flashtools, select the scatter file then program the phone, or did you use some other method?
Which clean ROM did you then install, and how did you install it?
Did you then use MobileUncle to install CWM then use the cyanogenmod 10.1 gapps, or did you do something different?
It is useful to remember that MTKdroidtools has a useful function to remove chinese stuff. I think if more people contributed to the list of Chinese files that are safe to remove, that would be blade.
A detailed step-by-step guide might be helpful for anyone else with the same problem. One of the general problems I find is that there are plenty of guides around referring to this program, or that program, but few are detailed enough for someone who doesn't already know about those programs to use.
I pretty much bricked a Lenovo A766 yesterday, and it took several hours to learn about the tools to eventually unbrick it.
I would have rather spent my time understanding what is really going on, rather than spending my time learning vaguely what tool achieves what end result. If I understood more about the Android system, and built that knowledge on my understanding of Linux, I reckon I could achieve much more.
One thing I notice is that tablets and smartphones are actually replacing desktops and laptops. February this year, windows machines were down 7% YOY. I use Ubuntu for my main computer. Using these tools on Windows led me to significant frustration! This has led me to understand why there is a move. Maybe the tools provided for windows need to eventually move to android. We could then potentially use USB OTG to service other android devices. MTKdroidtools and flashtools runnng as a host on a separate Android system would be cool.

Did you give it a try yet? Another user did and google apps are working for him, so thats 2 for 2.
Are you still on your original ROM? If so, I have a question for you. Do you get notification badges on your icons, for instance, when you have a missed call, is there a red box with a 1 on the phone icon? Also, do your contacts get ID-ed when they call you? I have some problems with that, caused by the country code prefix. I am still running that ROM I downlaoded from the Chinese forum, but if your ROM doent have these issues, I will switch back ASAP.

Where are configuration settings stored accross factory resets?
I have come to the (perhaps erroneous) conclusion that the user interface and what the user will experience is governed primarily from:
the APKs in
/system/app/
/system/vendor/operator/app/
and the configuration files pertaining to the installed apps, which is located at:
/data/user/0/
I guess that when the android device is factory reset, the /data partition is completely cleared, right?
Is there a set of standard configurations which are unpacked from somewhere into /data/user/0/ after a factory reset, or is it normal for all configurations to be stored in their respective APKs?
