You can manually install a custom recovery such as CWM Recovery using the fastboot or flash_image method if you don’t have a mobile internet connection.
With Fastboot:
For this method to work, you must have ADB and fastboot installed on your computer. Refer Get ADB working with A70
- Copy the recovery image from here to C:\
Note: The recovery image should have .img extension. If it is in a zip file, extract the .img file from it. - Power your device off. Hold the camera key.
- While holding the camera key, connect your device to your computer via USB and wait till you see ‘fastboot USB’ on the screen.
- Launch Command Prompt and type the following command:
fastboot flash recovery c:\recovery.img
- Wait for the process to finish and reboot your device once it’s done. You can reboot using fastboot:
fastboot-windows reboot
With flash_image:
‘flash_image’ is a tool for Android devices that lets you rewrite your phone’s system partitions with partition image files and installing it to your device requires ADB.
- Download flash_image and extract it from the zip file to a location on your computer. We extracted it to the main C drive (not in any folder) and will use that in the next steps.
- Download the recovery from here (A70) & copy it to C:\
- Enable USB debugging mode on your device from Menu > Settings > Applications > Development.
- Connect your device to your computer via USB.
- Open a Command Prompt window on your computer and enter the following commands:
adb push c:\flash_image /sdcard/ adb push c:\recovery.img /sdcard/ adb shell su mount -o remount, rw /system cp /sdcard/flash_image /system/bin cd /system/bin chmod 777 flash_image flash_image recovery /sdcard/recovery.img
This will first transfer flash_image and recovery.img to your phone. Then it will copy flash_image to the /system/bin folder of your Android device and make it executable. Finally, it will flash the custom recovery image to your device using flash_image.
If you extracted the files elsewhere, use the appropriate paths and if your recovery image has a different name, use the appropriate name in the first two lines. - Reboot your device once the process is finished and you’re done. You may exit adb and the Command Prompt window on your computer by entering ‘exit’ thrice.
