Recently my Wiko UFeel (using Marshmallow Android) restarted automatically and won't pass from the UFeel logo image. I know I problaby have to do a factory reset, however I need to backup some files to my computer, both from the phone and the SD Card which, unfortunately, is mounted as internal storage, meaning I can't plug it to a card reader or any other Wiko device to copy the files. What I'd like to know, please, is:

1) If I execute the factory reset with the SD card in my device, will the data also be erased or just the data from the internal storage (or both) ?

2) If I execute the factory reset without the SD card in my device, will I be able to use it as is after the phone is reset or will I need to format it ?

3) Is there any way for me to plug the phone to a computer so I can backup the files ?

4) Is there any way I can backup the SD card through some other means ? I tried ADB but it doesn't recognize my device.

Thank you very much

  • You should flash a custom recovery, such as TWRP, then boot to recovery and copy your data – esQmo_ Sep 21 '18 at 12:41
  • 1: probably yes, as it's formatted as internal storage. 2: definitely not, as your encryption key is lost after a factory reset. 3: if you've got the encryption key extracted, yes – see our adoptable-storage tag-wiki. 4: maybe, if you have a custom recovery installed. – Izzy Sep 21 '18 at 12:43
  • @esQmo_ not necessarily installed (correcting myself along); booting into one (fastboot boot recovery.img) should suffice. But that requires the bootloader to be unlocked. If that has not already been done beforehand, it will most likely trigger a factory reset, rendering the action useless for the current situation. – Izzy Sep 21 '18 at 12:44
  • Yeah, I forgot that model has a locked bootloader – esQmo_ Sep 21 '18 at 12:49

  1. As you formatted the card as internal storage, it will most likely be formatted at a factory reset (as it represents internal storage). Even if it wouldn't, you no longer were able to access it, as the encryption key will be lost after a factory reset.
  2. definitely not, as your encryption key is lost after a factory reset (see previous point).
  3. if you've got the encryption key extracted (which requires ), yes – see our adoptable-storage tag-wiki.
  4. maybe, if you have a custom recovery installed or can boot into one (fastboot boot recovery.img). But that would require the device's bootloader to be unlocked. If you haven't done so already, the unlock process usually implicitly performs a factory reset / data-wipe itself; so this approach only works if the bootloader already had been unlocked before (see: ).
  • Thank you very much for the help. My main priority is to salvage the SD card content, if I can. Is there a way to verify if the bootloader is unlocked with my phone this way ? – Gilgamesh0891 Sep 21 '18 at 15:56
  • Yes. When you boot into fastboot mode, there should be a command to list the status (something like fastboot oem device-info or fastboot oem INFOlock; fastboot oem ? should give you available commands for that). You can check our fastboot tag-wiki for additional resources, as well as the questions using that tag. – Izzy Sep 21 '18 at 16:15
