The following post is just a TESTED collection of tools and procedures that were found over at XDA forum or elsewhere on the Internet.
I do not take any credit for all those nice scripts and manuals - I just put them together for the young community of IdeaPad A2107A owners.
Below you will find methods of getting root and Clockwork Mod Recovery v 6.0.1.5 on IdeaPad A2107A (I own the -H version with dual SIM and ca. 4 GB of internal memory).
All processes were tested by me and are working well but obviously you are responsible for your actions.
My device runs on ICS 4.0.3, compilation A2107A-H_S341 and has a couple of European languages (tablet bought in Poland).
What you need is installed ADB drivers so the PC can "talk" to you tablet. You will find a lot of guides on the net - just make sure Windows device manager shows Android Device - Android ADB Interface or something close to that.
I also advise to enable USB debugging and allow installing applications from unknown sources - all in your tablet's settings.
Once you make sure you have done the above you're good to go.
So let's go!
Download this: http://www.mediafire.com/download.php?5o7dm16d430lwal (un7zip) and read as follows:
1 - Root
The method I chose is for patient people - the device will reboot 3 times during this process.
a) connect your tablet to the PC, open "1 - 4.03root" folder and run "root.bat"
b) just after you run the .bat the device will reboot and in the command prompt you will see "Press any key to continue . . ." - WAIT until the tablet boots up completely. When you see the lockcreen THEN hit a key in the command prompt.
c) the above will happen 2 more times - always WAIT for the tablet to boot completely.
This process will install Superuser and RootExplorer so find those apps and see if the root works.
2 - Backup the whole ROM that is on your device - will be useful with making the CWM recovery.img file.
For this you will need ca. 2GB of memory so I advise at least 4GB sdcard.
I also advise to go to the settings and in the memory tab set the "Default write disk" to "SD storage" - this makes the microSD the primary "sdcard" - makes things easier with backups etc.
ALSO in the settings set the screen to stay on for at least 10 minutes - this is how long it will take to do the full ROM dump - important to keep the script alive.
To avoid any issues turn the flight mode on so no new "data" is received by the device.
Once you're done open "2 - Backup" folder from my 7zip and copy the "gscript" folder to the root of your sdcard. Now install "GScriptLite.apk" and run it (needs root access!).
In the app hit the menu button and pick "Add Script" ->"Need SU?" must be checked -> "Load file" -> select "back_mt6575_a4_v2c.sh" -> save and click the script.
As I said - wait ca 10 minutes for the scrip to finish. Now you will have a nice backup in the SD - look for "backup_v2" folder - copy it to your PC.
3 -Mobileuncle - it's in the Google Play Store but you won't find it with our tablet - supposedly incompatible. Bull*hit!
Open "3 - Mobileuncle" folder, copy the apk to your device and install. We will come back to this later.
4 - How about the CWM? Yes!
Open "4 - CWM 6015" - you will find a PDF there - read the instructions. The subfolder "michfood" contanis all the scripts you need so you don't have to download anything else.
ATTENTION - the "recovery.img" used in this process is YOUR "recovery.img" that you dumped in step 2. So find your backup from step 2 and the original "recovery.img" from your ROM.
ATTENTION - our device is MT6575 so you pick nr 1 in the command prompt.
5 - Once you have the new "recovery.img" with CWM (it is actually smaller than the original file) copy it to the root of your sdcard.
Now open the Mobileuncle Tools you installed in step 3 and hit "Recovery Update".
There, at the very top of the screen you will see your new CWM recovery file - hit it and then confirm the update. It takes a second!
Now you will be asked to boot into recovery mode - go ahead, try it
If the tablet booted in CWM then you are all set!
REMEMBER - to go into the recovery mode while the device is OFF you need to:
1 - hold the power button for ca 3 seconds
2 - let it go and in the same moment press BOTH Vol + and Vol - buttons.
REMEMBER 2 - the CWM 6.0.1.5 makes backups in a bit different way than the old CWM - read here :http://xdaforums.com/showthread.php?t=1846446
It also appears that the key to modding our tablet is the MT6575 processor - a lot of tools just need to support this processor, the device itself is not so important.
All the best.
Mike.

------------------------------------------------- UPDATE 1 ---------------------------------------------------------
For those who are running the same compilation as I am (A2107A-H_S341):
- you can download my recovery file from here: http://www.mediafire.com/download.php?um372gh6ayf6t6w
To use it you need to do:
1 - Root
(optional backup with GScriptLite.apk)
2 - flash the recovery file with Mobileuncle
Be careful and make sure you have a backup if you want to try this file with another compilation.
Cheers.
------------------------------------------------- UPDATE 2 ---------------------------------------------------------
Tested (by user: manwithmanypiercings) USB drivers are in this post: http://xdaforums.com/showpost.php?p=34651039&postcount=51
------------------------------------------------- UPDATE 3 ---------------------------------------------------------
I think there is even easier way than the one I originally posted above.
BUT I cannot be sure that it will work with all of you - the reason is that I made so many changes to my A2107A-H that I do not know whether this method works "just because it's universal" or because my tablet was tweaked far enough.
On the other hand when you consider it reasonably it looks like it's quite simple and there is no particular reason why it shouldn't work with a stock A2107A.
So...
What you need:
1 - this package: http://www.mediafire.com/download.php?fbuzi5xjofs7vgf
2 - PC running Windows 7 would be the best (7 gave me no problems at all - takes 1 minute to do it). I made it on Windows 8 as well but there is a lot more fuss to install the proper driver.
What you do:
1 - turn on USB Debugging on your tablet
2 - connect the tablet to your PC (if it's the 1st, some default drivers will install - that's ok)
3 - tap on the notifications area in the "Connect as" change to "MTP" - this is quite important !
4 - from the downloaded package run the "Flash_tool.exe"
- click "Scatter-loading" on the right and find "MT6575_Android_scatter_emmc.txt"
- in the list in the lower part of the window you MUST have the "PRELOADER" (super important) and "RECOVERY" ticked and leading to the correct files. The PRELOADER = "preloader_lenovo75_a2_ics.bin" (in the package) and the RECOVERY is the recovery file of your choice -> there are 3 in the package - pick the one you want. You can flash them over and over so if you don't like one then try the other.
5 - click "Download" above - you will see a prompt saying that not all images were loaded - that is fine - we only want to flash the RECOVERY - so click "Yes"
6 - now the Flash tool is waiting for the tablet - press "reset" on the back - Windows will recognize a new device (and WILL NOT find the driver unless you have done it before) - no worries, you have the correct driver.
7 - open Windows "Device manager" and locate the MT65..... unrecognised device -> update / install driver -> point Windows to "USB VCOM Driver" folder from the package and pick your system. My Windows 7 found the driver on the spot but asked to confirm the install - "insecure" driver - I obviously clicked "install anyway" and so should you.
8 - once the driver is loaded the Flash tool will flash the new recovery file - you will see some colour progress bars in the program - at the end you should see a green circle.
That is it. Unplug the tablet, press reset on the back and you can now enter the recovery mode.
FUN FACT: the "reset" button on the back is not really a reset button, it's more like physical cut off button to temporarily disconnect the battery.
