How to increase the internal memory in ACE 2.
(Anyone who doesn't have an external SDcard installed shouldn't do this tutorial or all the space will be lost, but in this case you can do the tutorial number 500.txt or 750.txt)
The internal SD memory will be deleted after doing this, so make sure of back up your files.
It is necessary to have ROOT access and have the swap memories activated.
Unzip the file adb.zip
Put the folder "adb" in the main hard disk (usually c:/ )
On the phone go to settings/ developer options/ check USB debugging box (debugging USB activated).
Connect the phone to the PC and see if it asks for the drivers "adb" that are in the folder "drivers". After that disconnect it again.
Reboot in "recovery mode".
Make a nandroid backup -> Backup and restore -> backup to/storage/sdcard1
Go to "mounts and storage" and configure it like this:
unmount/system
mount/modemfs
mount/cache
mount/preload
mount/data
mount/storage/sdcard0
Now stay on that screen!!
Connect the phone to the PC. If you have never done anything in USB mode, it will ask you for the drivers. (You will find them in the folder "Drivers", x86 & x64 drivers).
On the PC go to the "Command Line". (If you are using Windows7 or 8 make a right click and run it like administrator).
Open the xx.txt file you want to use. The number means the MB that the USB memory will have (second partition).
These files are made to be cut and pasted directly to the "System symbol" window (this way you can not insert the same command twice).
When we write or paste each line, we have to press "Enter".
IMPORTANT!!!
After pasting the "Adb devices" line and pressing "Enter", it has to show RECOVERY, if it shows OFFLINE, unplug the phone, reconnect it and paste the line "adb devices" again.
Continue adding all the lines until the end.
Disconnect the phone (the phone screen will show a few errors E: Can't open... / E: Can't unmount... (Do not be afraid, it is normal to see that and that is how it is).
Make wipe cache, wipe dalvik, wipe data.
Go to Mounts and Storage Menu ->Make format /system, format /data, format /cache, format /storage/sdcard0 (default)
Backup and restore -> Restore from sdcard 1 -> Restore copy from xxxxx
Optional wipe cache and dalvik cache.
Reboot.
You have already created the partition and restored the phone. Now, go to "Settings/ Developer Options/ Uncheck USB debugging box.
ENJOY!!
