Hello, I have a relative's Kobo Clara HD N249 that has been left with the restore screen, I have removed the SD card and it appears damaged. I bought another card and I put a Kobo Clara HD .tgz file but it doesn't do anything no matter how long I press the button. Can you send me the image that is not in .tgz, I have read that two hidden partitions must be created. Thanks for the help.
