I was given an Archos Diamond S phone to repair. The phone can't boot after an OTA update, it's stuck on the booting screen (no boot loop).

When it's stuck on the boot logo I can access the files however this is really slow and make explorer.exe crash everytime I want to perform an ation. Furthermore I want to access the root of sdcard so I can backup some apps data.

The only think I can do is boot in factory or in recovery mode. However in recovery mode I can only use adb in sideload mode and can't pull anything. I could try to force the OTA update via adb but I can't find the firmware for this model.

I then wanted to install a custom recovery that would enable android debug mode (like TWRP) and pull files with adb but I didn't find any for this model.

Do you know any way I could access the phone storage and create a backup of thoses files before wipe data/factory reset ?



Use ADB.

  1. Connect your device to PC/Mac in Recovery mode.

  2. Test connection. Type ./adb devices (MAC) OR adb devices (WINDOWS).

  3. Assuming you want to download DCIM folder, type ./adb pull sdcard/DCIM <optional_dir>

Use ./adb on Mac and adb on Windows.

You can also download the complete /sdcard folder as a full backup.

  • USB Debug was not activated on the phone. Thus I can't do that, my computer won't detect the phone using adb. That's why I wanted to install TWRP so I can use adb.

  • read this to enable USB debugging using ADB: android.stackexchange.com/questions/120394/… Oct 10 '17 at 10:23
  • The device is not rooted and is not detected by adb except when in sideload mode.

  • I checked my guide on my Nexus 5 which is not rooted and USB debugging was OFF. I was able to 'pull' files. Oct 10 '17 at 11:46
  • I will give it a try tonight. However I know the device doesn't appear as "connected" while in recovery mode when I adb devices
