Phone worked fine until the other night when mid text the screen just turned off. now i tried to turn it back on and it simply vibrates when power button is pressed however the screen will not boot. i cannot boot into recovery or even download mode and by pulling the battery and plugging it into the pc i get a red LED like it is charging but it goes off after a few seconds or so. So yeah i need help!
Brick due to Sudden Death
FWIW, I had something similar to his happen to me today. It turned out that despite showing a full charge on the battery, the battery simply ran out. I plugged it into a charger for a while and it fired right up.
To be clear the symptom I was experiencing was that my screen shuttered and then my whole phone died. When I tried to pull the battery or power on in any way, I'd get a short vibration pulse and then it would die again. I also cycled through the different key combinations trying to connect it to my computer, but with no success. Once I saw the red led charging indicator, I knew I wasn't bricked, so I just left it on the charger and let it continue to do the vibration pulse repeatedly until it had enough charge to display the on-screen charging indicator. Once I had that, I let it go a while longer and then tried to power it on and BOOYA! We're back in business.
Sometimes the solution to a tough problem is to simply do nothing. Who knew?
I am having the same issue. My bud has the same phone and I swapped batteries, still boot loop. It seems after some research that the problem is the power button contact not opening. I have seen two videos now where people de-solder or snap the power button off (after metering it) and softboot the phone via their PC to recover their data...
I will be switching out my board for my friends tonight to see if his button panel will do the same thing...
Long troubleshooting process for this one.
