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 ?
