Hallo Everybody,
I'm new to flashing/rooting/etc. on mobile android devices, but since my Motorola RAZR I is stuck at the red Motorola logo, it is time to gather some experiance.

As said, the phone stucks at the Motorola logo, propably a bootloop. Fastboot access is possible, it is also possible to get into the recovery menu. But when I try to connect adb via the recovery menu option "apply update via usb" my PC (Win7) gets an "Unknown Device" in the Device Manager under USB-Controller.

I used adb before for playing a little bit around, so all Motorola drivers for the normal debug mode work, but I don't find a driver for the "Unknown Device" (recovery mode adb).
I already tried different USB cables and restarted my PC serveral times, but still no driver for the "Unknown Device". I also tried the Intel Driver update for android devices and forced to install the Motorola drivers for this "Unknown Device" but nothing helps.

I wanted to try to download/backup some files from the internal storage. Afterwards, I want to flash a lineageOS.

I also searched a day in the internet and in this forum but I didn't find a solution. Sorry if I didn't find the Solution-Thread.

Has somebody an Idea?
Many Thanks in advance.
