My phone seems to be hard bricked: black screen, nothing happens when trying to charge it, not possible to put it in DL mode, and even usb jig is not working.
Now I'm fully aware of the risks that go with a bad flash, but what is weird in my case is that it happened out of nowhere: I was on stock rom, phone was suffering from a bad case of slowdowns/random freezes/etc so I decided to put CM 11 on it. Like a phoenix my phone rose from his ashes, battery was holding for a full day instead of the usual 3 hours, no more freezes... but then after 2 days of working like a charm, I just found it plain dead on my desk.
Has it ever happened to anyone, suffering that kind of brick a few days after flashing but not during the actual procedure ? Does anyone has a potential solution other than replacing the MB ? (not really worth it on a 2 years old phone IMO, since there is little chance that I will stumble upon a free MB, and I'm not even sure that it would solve anything anyway)
Thanks for your help !
