2. Introduction to backup and restore functions
Enter the backup partition, generally check all partitions for complete backup, and then click "Set backup file name", set a name such as A870L-115-CHS-20130808, and so on
You can tell what phone this ROM is used for, which version, and when it was backed up by the file name.
Explain what each backup partition does
System:系统分区，存放整个安卓系统
Data: Data partition to store user data.
Boot:启动分区，包含内核负责启动。
Recovery:这个就不用说了
Cache:缓存，可不备份。
modem:基带分区，建议备份。
rawdata:存有串号IMEI的分区，建议备份。
The following information is collected from the Internet and through my own practice for your reference. If there are any inaccuracies, please correct them.
Brush the ROM must be unlocked Remember to unlock!
Enter recovery mode:
[Turn off, press ("Volume Up" + "HOME" + "Power on key") at the same time to enter recovery mode]
★★ Ordinary double clear ★★
Normal double clearing is to select in recovery mode:
1: Wipe data/factory reset
Note: Clear the /data (program data) and /cache (system cache) partitions (clear user information and software information), and in the commonly used CWM (such as CWM-based Recovery v6.0.5.0), it also includes formatting /sd-ext and /sdcard/.android_secure partitions;
2: Wipe cache partition
Description: Only format/cache partition (clear system cache), only used to restore problems after flashing the system!
★★ Siqing explained ★★
The so-called four clears of the brushing machine are on the basis of double clearing, adding the following two:
3: Wipe dalvik cache
Description: Advanced feature -> Clear dalvik cache
Note: When Android boots, you need to establish a trust branch for all programs to optimize cache files for faster startup. After wiping or brushing the system, the initial boot is very slow, because this file is not established, and the startup will be faster in the future.
4: Format / system (format system partition)
Description: Mount and Mass Storage -> format /system
★★ Liuqing explained ★★
The so-called six clears are based on the above four clears, adding the following two:
5: Format / SDCARD (Format the phone's built-in memory card)
Description: Mount and Mass Storage -> format/sdcard
6: Format / storage / extsdcard (format the phone's external TF card)
Note: Mount and mass storage -> format /storage/extSdCard
The various ROMs of the forum are constantly updated, and one thing is very important, that is, whether it is a line brush or a card brush, four clears are very necessary, and I hope the engine oil will attract attention! Otherwise, there will be very mysterious events, such as others have no bug after brushing, why did I have this or that problem, basically caused by not completely removing the remnants of the original system, and I can't think of a problem and have to clean and thoroughly oil don't be lazy! |
