1-how the repartition is done, is it part of the ROM it self?
P780_LiFe_v02_ReParted_Data_aroma.zip is not a rom, it is a program written by Russian to repartition P780 phone internal storage. it just like CWM recovery update.zip or gapps if you use cyanogenmod before. your original rom still remain only thing will lost is the data in your build in storage so please backup your build in storage data to your external storage and set the default write to external storage after repartition it!!2-after i flash the rom and repartition is done, if i want to recover to stock rom, I just recover by pressing the "reset" at back of phone? or what is the step to restore stock rom+unroot?
if you want to recover, you need to flash the stock rom back from needrom S110 29 June 2013 or i found the latest rom S116 28 Aug 2013 http://lenovo-forums.ru/topic/2146-romp780...1-%D0%BF%D0%BA/
After flash back stock rom it back to unroot condition again!!
I found the S115 rom but it is an OTA update (11MB) and i dont know why i cant flash in or update to S110 rom using mobile uncle CWM recovery maybe TWR can do it, but i never try!! 3-after recover to stock rom, will the partition goes back to original setup where internal storage = 2.14GB , built in storage = 1.45GB?
after flash back either rom the partition table will reset coz the EBR1 & 2 flash back to original.4-do you experience any issue with lagging/performance issue by setting only 4.98MB in built-in storage?
Even My P770 i partition it to 3.3G and 3XXMB free on build in memory, i use it for almost 6 months never found any lagging problem even dont have a hang or restart issue like galaxy S2. coz i set the default write to External storage so the build in storage become useless i just store my mp3 song and ringtone. P780 still not yet run in live after repartition so i cant comment it now coz still under testing but so far so good even i try dual sim today.... but i think will be the same coz using stock rom didnt change anything except partition and default write location.
of coz you need a fast microSD card to have better performance. my microSD is 30MB/s.
you can also have a simulate environment to set the default write to external card use it for 1 week see got any laggy problem? only problem is custom ringtone issue.. each time you restart your phone need to set it back again coz the preparing of external storage slow when startup. so ringtone put in build in storage or use system ringtone lo!! then you find out that your build in storage become useless!! 
Hi Gary,
Thanks, after updating base on your post, i have now 3.56GB on my internal storage. However I am facing a few problems:
1- i tried phone rest (as i wanted to try unroot) but it stuck in CWM and does not work even reset with CWM. After next reboot, it stuck at lenovo screen, are you facing this problem? Any solution?
2-i cannot see and cannot access the 3.56 internal storage, nor via windows when connected via usb, do you have same issue?
3-is the russia firmware same as malaysian firmware? I guess no ya? Where can we find malaysian firmware (ori one come with phone)? To flash this we need to use the flashing tool, or CWM?
4-how can i undo the partition if i need to send my phone for warranty claim?
Thanks again.
