@pikolinjavi Ya hay hilos de doongle y sobre tu duda decian que habia 2 versiones de ese doongle el que tenia micro sd actualizableby el que no. Segun decian el actualizable se hacia asi
1. download the payload of your choice and rename the payload to "payload.bin"
2. copy "payload.bin" to the root of the sd card
3. put the sd card in the dongle
4. enter rcm mode
5. plug in dongle, you'll notice that the red light flashes much longer
6. once you have booted you can take out the sd card, the dongle is now updated w/ your new payload and no longer require to be present in the dongle.
