I. What is recovery?
Recovery is a micro-system, which can erase all partitions of the mobile phone, that is, we often say that the computer swipes the card in recovery mode, which is similar to the installation of computer Ghost;
Every mobile phone comes with its own recycling, but it can only be swiped into the brush package signed by the manufacturer; So we need to brush in the third-party recovery, bypass the official signature, and brush in the resource-rich third-party rom package.
To get this third-party recovery, you must first ROOT the system, that is, get the system modification permission. Generally, recovery can be swiped after S-OFF, because most of them are swiped into the third-party ROM with recovery, and it is impossible to swipe into the third-party ROM in the unlocked state. It is of little significance to recover at this time.
Tools/raw materials
You can download several brushing tools to brush into the third-party recovery software, such as: sweet pepper brushing software, brushing wizard, Zhuo Dashi and so on.
Methods/steps
First, the user first checks whether the mobile phone is restored by a third party.
If the mobile phone is equipped with third-party recovery, you can skip this step, otherwise it will be brushed into third-party recovery:
Open the Brush Assistant-Utilities-Brush to resume. Here you need to know whether the brush software mentioned in the first article supports your mobile phone.
This model is not supported. You can search for other methods on the network and brush in recovery.
Good news: Sweet Pepper has supported the refresh of mobile phone recovery mode. If your mobile phone is in recovery mode, the connection software can be refreshed with one button, which saves the manual trouble later.
Copy data
Brush the compressed card package (which can be downloaded from rom Mall) and store it in the root directory of sd card. Its general format is as follows (otherwise, it will be slightly processed by itself):
(If you can't boot the copied file, use a card reader or mount the USB flash drive in the mount partition in recovery mode. )
Enter the recovery, please refer to here for the method.
Clear data/cache
In recovery mode, use the volume key to select up and down, and confirm with the power key /home key (some models have different key values, so users need to test them themselves);
(1) clear the data and return to the main menu after completion;
(2) clear the cache and return to the main menu after completion;
