My internal sd card died slowly over time. It failed to mount on some occasions at first. After a few weeks I had massive app crashes.
Everything I did on the phone (installing apps, deleting files, even doing a factory reset) seemed to revert back after rebooting the phone. I mean I delete some files, and after reboot, the files came back from the dead. Same thing for factory reset.
Installing other roms made the situation even worse, and I had to revert back to stock 2.3 rom.
And since last week, the phone is on permanent bootloop. It won't go into download or recovery mode (it used to activate those modes with 3 button combo before).
I tried the USB JIG method. Built a 301k resistor, connected pins to the usb thingie. It did power the phone on, but failed to trigger the download mode. The phone still goes into a boot loop.
Anyone has any ideas? I don't know what more information I can provide about the issue.
