Hi,
quick specs before the tirade:
Brand: Ployer
Model number: MOMO
Firmware version: v2.2.1_00.04-CN *at* 20110625
Kernel version: 2.6.25_(V2.2_3_718DC(E8_R8)_D2_RHJ_A18* at *0728)
Build number: froyo1.00 MASTER.eng.root.20110323.164551
Android version: 2.2.1
CPU: Rockchip 2818, ARM9, 660MHz
Screen: 7.0 inch TFT, Resistive Touch screen, 800*480.
No external hardware buttons for navigation or volume. Only Power button, menu and esc buttons on the top side of the tablet.
* had to replace at symbols because I am obviously sending email addresses or something... *
I'd also love to link the device so people can see what I am referring to if that helps... ployer momo2 should find the ployer.cn web.
--
I am sorry if this does relate to another thread, I am still trying to work out where I am at with this thing, and do not know enough, and I've been searching for days and days putting off posting and hoping it falls into place, but no luck.
I have a Ployer MOMO2 device, which is a cheap Chinese Tabet, no phone, no camera. Here is the URL to the device: .. well i would but cant link.
My problem is I need to get root access to this. I would ultimately like to have a fresh install on it entirely, as everything is in Chinese up until it boots into the os.
There is no Market app on it, and any websites that need flash try to redirect to market: which the device has no idea about. So, I need Market but this is only part of the reason. I cannot uninstall the default Chinese apps, and I cannot use them either.
I also know it has a cramfs filesystem, which is the reason I cannot perm root using z4root. And unfortunately, z4root also fails to temp root the device, failing and then locking up the tablet, or freezing it requiring a cold reboot.
I have tried various version of r4root, having read others have had success. Not so.
I downloaded rageagainstthecage-arm5.bin which is suposed to work with android 2.2.1, and executed it using a terminal app, which proceeded to fork processes and can adb. However, that is where the success ends.
The terminal freezes, as expected, and I force close it. Reopen it to check root, but it won't open. The only way I can access the terminal now is to reboot the device, thus losing any temp root access.
Ugh.
I've tried 1click, as well as other recommended once, but not having the options to boot into recovery/bootloader etc, I cannot complete any instructions on those guides.
I also just wanted to see how I could go about the process of updating the system, using update.img on the sdcard, not intending to do it, but to just gauge the process for now.
It detects the image but says it's corrupt and asks me to delete it.
This was the update.img I got OFF the tablet. It wont even accept it's own? Nah Im doing something fundamentally wrong.
I've been trying so many things, I'm lost.
I simply need to know which direction to attack this issue, and I've seen other rk2818 images out there that have been edited to include root access and market, so for those guys it's possible.
Can someone please offer any advice, keeping in mind I'm not well versed in this, and may require more than cliffs notes...
I really do feel as if I've made complicated something that does not need to be so.
Thanks in advance for any help,
Cheers!

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,
About 5 months ago I bought a pink phone, I would like to have full control over the system. I tried to root in different ways but it does not work for him. Unfortunately, the drivers on the internet you can not even get the usb to work as it should. I downloaded from the manufacturer update the file as I found out it is a complete room system. And here begins my question is where the power to change my root privileges? Can anyone has had with this phone to do, he did something like that, or can I modify the package properly?
I ask for help if you need any information please write.
Regards
SB
hi. really i just want my phone to be sure to clear from any malware, but this could also be a request of how to flash a new OS if this is needed. the phone runs as slowly as it ever did so i can't see any major difference in that. one thing is that a data usage app shows no increase in data since the possible infection, even though i know i am using the mobile data. and this seems strange as though something could be blocking this to hide its own communications.
i rooted my UK android phone with kingoroot a while back to gain SU access to allow me to store apps on the external SD card. that was ages ago and i don't access to the same windows PC. (i have a linux'd laptop)
foolishly i clicked on a whatsapp message with a 'free voucher offer' link, even though i though this was too good to be true and i knew i shouldn't click on this kind of nonsense.... i have since installed norton antivirus and it says the phone is fine, though i am still dubious that the app can check for any malware that may have entered into the lower levels of the system given kingoroot has messed with the access controls. for now i have removed any apps that have my bank details
i have read that in these circumstances even factory reset may guarantee clearing anything. is this correct? so am i right that the only way to be sure the phone is clean is to re-install a new boot loader and OS?
if so, this is a little beyond me and i find conflicting instructions as to what to do, or where to download the correct files. i find more links to installing non- standard android 4.3 or 4.4, with reports that these maybe aren't stable. if they are OK i'd happy with these, but 4.1.1 does most of what i want (apart from the lack of internal memory and not being able to store apps on the external SD)
would doing a firmware update to a newer version B209 do the same? (mine is currently B197) i can find a link from a place i trust from github, and if this helps the phone run better then i would be up for doing that anyway but again would not know how to.
do i have to undo the Kingoroot before i start any of this? is the CNET download link for kingoroot safe to use as the kingoapp.com website doesn't work for me anymore.
massive thanks in advance for any thoughts on this

Greetings and welcome to xda. Factory resetting or reflashing stock firmware should wipe any offending program so you will be ok there. If you ask your question here
http://forum.xda-developers.com/android/help
hopefully the experts there can help you with kingroot
Good Luck
