I'm pretty sure you can, but I would update incrementally.Quick question here. Sorry if I sound a lil ignorant I just want to make sure I don't brick my phone. I haven't updated my rom in a while and I am still on the LJ7 version of the firmware. My questions is, can I upgrade to MD4 directly from LJ7, skipping MB1, by flashing the MD4 Firmware/modem/baseband update ? Thanks in advance!
