Yup but china version i didnt try the need rom version...
but coz i flash 3.6G (without build-in storage) rom 1st and miui sit on top of this 3.6G rom so very unstable and the whole phone laggy. specially after flash in google apps.

i recommand you to flash after doing the repartition you need at least some space in build-in storage (now i left only 4.xMB) or you flash miui rom without changing the partition.

by the way may I know the default ROM version for your phone?? you can check it in settings->all settings-> about phone-> version info->build number

and Please take note that our P780 is international version. flashing china ROM sim2 may have problem due to baseband different.

they said got solution from Russian web but i didnt try coz in malaysia i dont have sim2 to try.

refer this web

http://bbs.ydss.cn/thread-328118-1-1.html

it is the same in malaysia too. this phone is dual sim standby 双卡双待.
My friend p770 using celcom for sim1 (personal line) and maxis for sim2 to call (company line).
his data is always on, coz this phone will cut off data while you connected to wifi and of coz if your wifi week the data will automatically on back... just like normal android phone.

which rom u tested? still have the lenovopower app? i kind of like this app though.. currently i am using framaroot to gain root...what to do after gaining root? thinking of getting link2sd...

with original rom you want move your apps to sd dont need link2sd you can use the default that in setting-> app -> sd storage
just tick whatever you want to move to sd

thanks for sharing

Thanks Gary for sharing this, may i ask a few questions:
1-how the repartition is done, is it part of the ROM it self?
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?
3-after recover to stock rom, will the partition goes back to original setup where internal storage = 2.14GB , built in storage = 1.45GB?
4-do you experience any issue with lagging/performance issue by setting only 4.98MB in built-in storage?

BTW, the rom come with the phone I am using currently is P780_ROW_S115_130807, baseband version P780.V20, 2013/07/31 10:51, hope this is what you were looking for.

Thanks so much.

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!!

For those want to know more about dual sim,

today try it and found out that call log indicator call from which sim is too small with a number "1" or "2" not like P770 different it by using color and name which set in sim management. for uncle like me is a bit difficult to see!!

SMS still ok coz there is a sim name display on right bottom corner but also without color. P770 got name and color without number!!

good thing is P780 got a new function that SMS and Call ringtone can be set by different sim. means sim1 & 2 can have different ringtone and sms notification.

I tested this in S116 ROM dont know the S115 ROM having the same problem?

RAM still a issue like P770 coz both using 1GB RAM but this time lenovo launcher add a cleaner function but dont forget to set white list in preference!! if not, you will found some of your program not function well after clean ram

the lenovo power is the best improvement!!! can manage and whitelist or blacklist so many things and so stable compare with juice defender i use in galaxy s2!!
