There is a problem here, that is, what is the situation of cloning between partitions of different sizes?
The answer is: if the 80
speed of the mobile phone.
We often say that it takes only two steps to install the software on the SD card in three steps to install the elephant in the refrigerator.
Division software requires ext3
First, we need to partition the mobile phone SD card by a FAT32 partition and an ext3 partition. The FAT32 partition is used to normally store images, music, videos, and other materials, in Linux format, ext3 partitions are used to expand the partitions used to install software. Taking the au
information about app2sd +, see the post I mentioned above.
2. Partition your memory cardThere are two ways to achieve this:
Method 1: Use the partition tool on the PC to partition the memory card!(We recommend that you first try method 2 below, but you need to read the partition mentioned in method 1 .)Common partition tools such as acronis disk ctor and diskgenius can split the memory card into both the ext format and the fat format.(PS. When I use

Modify the Registry as follows:HKEY_LOCAL_MACHINE/system/CurrentControlSet/control/Session ManagerThere is a primary key: bootexecute. Its original value is: autocheck autochk *However, after the Chinese version of acronis disk ctor suite is installed, it becomesAutocheck autochk * autopartntDelete the added autopartnt and
