Hi I have helped some friends updating their SGS phones with the new software from the samsungfirmwares website. However, now I'm stuck with a problem on one of the phones: It simply won't go into download mode. Normally, I press the volume down + menu key and while pressing them I push the power button. But nothing happends, excemt the phone starts up just like normal. I've done it the exact same way with all the models, but this model does not react like the rest of them. Today, I succesfully updated 3 models this way, but model number 4 would not go into download mode. The model has the JM2 firmware now. The other 3 models had JM1 firmware, even though they were all purchased at the same date. Is there another way of getting the SGS into download mode?
