@electroteque

to get to a recovery mode

Would you describe the Recovery mode as similar to the image, that is an unmodified Android Recovery? A confirmation would be to see if the phone still boots correctly to system, Download mode and Recovery mode which is capable of booting back to system, confirming an Original Android Recovery.

Your partial log seems to show a valid Recovery upload command

“C:\Program Files\easy-installer\bin\heimdall”
flash --RECOVERY ““C:\Users\danielr\AppData\Local\easy-installer\sources\dreamlte\recovery-e-latest-r-dreamlte.img”” --no-reboot

The downloaded and available Recovery is e-Recovery.

Then

(debug)Detecting device…

This was the reply I gave for another lbusb error: -12 case

@aibd

Libusb errors can derive anywhere is the usb chain from PC motherboard to device.

Without doing a fuller analysis, try a different cable (a cable can transmit data and perform parts of the install but fail to communicate with Download mode – it has been reported that an original Samsung cable behaves this way !).

Secondly, some USB hubs should be avoided. Sometimes a mix of different USB ports might be provided through such an internal hub. (Often at the front.) Try to use the USB port actually soldered to the motherboard. (Usually at the back.)
