Lenovo IdeaPad A2107A
ROOT+CWM 22.214.171.124] Lenovo IdeaPad A2107A(-H)
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 126.96.36.199 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 you 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 Window 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: (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.
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 188.8.131.52 makes backups in a bit different way than the old CWM - read here :
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.
