I can't believe what happened to my phone. It was working perfectly up until a few hours ago.
I tried flashing ElementalX v8 which I have been running for months with no issues, as I wanted to change some of the settings. After the flash, it showed it was successful, but there was also another line similar to "E: cannot mount partition". Can't remember exactly. I went to wipe cache and dalvic manually as I always do, then saw a few more lines that looked similar to that, then after tapping Reboot the System, my phone powered off and hasn't worked since. The battery was at 21% and plugged in at the time, which I suppose is risky, but i've never had a prob before. I flash ROMs. radios and kernels a lot.
My phone will literally not do anything at all right now. The LED isn't even on while it's plugged in to it's wall charger, it won't vibrate, flash anything on the screen. Absolutely nothing
I have tried holding power button for up to a minute while plugged in and unplugged, and also, held volume down and power for up to a minute while plugged in and unplugged.
When I connect it to my PC, it shows a device with a driver error "qhsusb_dload". From my research, it seems that I will need to send it for JTAG service or try the steps in the "unbrick evita" thread, which I will, after leaving it plugged in overnight.
I would like to know:
Can I resolve this by purchasing a used Logic board, either from the AT&T or International version?
Can a replacement battery resolve this? A friend has the same phone with a broken LCD that he's scrapping
Is there any possibility it will start working again if it was just left plugged in for hours?
I am in Jamaica and this is a really sticky situation for me. I can't even get a phone out here to use a MicroSIM :-/
I'd appreciate any help at all. Thanks
