I think this user @awwar
describes an inability to access download mode>here
. In anycase, I think that thread would be a great place to post your unbrick. image. I think your dd image seems too small. But if you still have it, that is what @moomoo
was asking for when he started that thread. I can't provide mine, except as separate img files. My understanding is that flashing an efs image won't provide a real IMEI. I think flashing some combination of boot, system, cache (I'm surprised this would be necessary) and recovery should get the operator some kind of system. But so far it doesn't seem to work that way. Your help getting some working phone flash would be greatly appreciated. I believe, BTW that the OTA is dead...
