failed to remount partition dev:/dev/block/dm-0 mnt:/system: Read-only file system，怎么解决

这个错误通常发生在Android系统中，表示文件系统只读，不能写入。这可能是由于系统出现错误或者权限问题导致的。以下是一些解决方法：

1. 重新启动设备：尝试重启设备，看看是否可以正常启动。

2. 检查文件系统：使用文件系统检查工具，如fsck，检查文件系统的完整性。你可以通过在终端中运行以下命令来检查文件系统：

   su
   umount /system
   e2fsck -f /dev/block/dm-0
   mount -o ro,remount /system

3. 检查权限：检查文件系统的权限是否正确设置。你可以通过在终端中运行以下命令来检查文件系统的权限：

   su
   chmod 755 /system
   chown root:root /system

4. 卸载和重新安装应用程序：尝试卸载和重新安装可能导致该错误的应用程序。

如果以上方法都无法解决问题，你可能需要考虑从备份或者恢复设备出厂设置。请注意，这将删除设备上的所有数据，因此请确保提前备份重要数据。

failed to remount partition dev:/dev/mapper/a_system mnt:/: Permission denied

这个问题通常是由于权限问题导致的。你可能需要以管理员权限运行命令来重新挂载分区。你可以尝试使用 `sudo` 命令来执行这个操作，例如：

sudo mount -o remount /dev/mapper/a_system /

这将以管理员权限重新挂载分区 `/dev/mapper/a_system` 到根目录 `/`。如果你没有管理员权限，你可能需要联系系统管理员或者使用其他方法获取足够的权限来执行此操作。

remount of /system failed: Read-only file system

The error message you encountered, "remount of /system failed: Read-only file system," indicates that the /system partition on your device is currently mounted as read-only. This means that you cannot write or make any changes to the files in the /system directory.

To resolve this issue, you can try the following steps:

1. Reboot your device: Sometimes, a simple reboot can fix temporary file system issues. After the reboot, check if the /system partition is still mounted as read-only.

2. Check for errors: Run a file system check to identify and fix any errors on the /system partition. You can use the fsck tool, specific to your device's operating system, to perform this task.

3. Clear cache and dalvik cache: Clearing the cache and dalvik cache can sometimes help resolve file system issues. You can do this through the recovery mode of your device.

4. Remount manually: If the above steps don't work, you can try remounting the /system partition manually using the following command in a terminal or through adb:

   adb shell
   su
   mount -o rw,remount /system

This command will attempt to remount the /system partition as read-write.

If none of these steps work, it is recommended to seek further assistance from the support channels specific to your device or consult with a professional.
