Welp, I've really liked this phone for the 6 months I've had it, but it appears to have cooked itself today. Was using it just web browsing today and it froze up (screen was still animating but other than that completely unresponsive). Held down the power button as you do, turned it back on entered pin and it sat on "android is starting" for about 10 minutes. Force powered off again and rebooted, same thing but I left it on "android is starting" for a good hour and still nothing. Turned it off again, this time no more boot. Black screen, zero signs of life. No combination of buttons will make it do anything. Bought it home, sat it on the charger for a few hours and did all the googling.
- I've got the SP flash tool and 2019090319 rom.
- I installed the Mediatek SP drivers 20160804
- When I hold down power for >10s and then release (not connected to the PC) and then I connect it, Device manager sees "MediaTek USB Port (COM#)". But when it's like this it connects, and then disconnects after 2seconds or so, over and over in some kind of loop.
- I have tried to use the SP flash tool with it like this (tried download only and firmware upgrade mode, same result), the tool appears to recognise the device and attempts to start sending data (and the phone stops disconnecting/looping) but in a second it gets to a red bar with "Download DA 100%" and hangs there for about 2 minutes, then gives me the error STATUS_PROTOCOL_ERR (0xC0010005).
- I've tried different cables, different ports and a second computer with the same result.
- If I hold down the volume down button while I connect it and keep it help down, it consistently shows up on the computer as "Unknown USB Device (Device Descriptor Request Failed)" and does not do the on/off cycling.
- When I release volume down and hold power for ~10s and release it goes back to being the "MediaTek USB Port" and does the on/off cycling again.
I'd love to get this thing working again but I'm at a loss. The only thing I haven't tried is the "Format All + Download" option in SP flash (cause every site says not to). I do have the box with the IMEI's on it for what it's worth though, so I'll probably see if that does anything as a last resort.
If anyone has any ideas on how I might be able to recover this I'm all ears.
