Sorry Chronogeek if I disturb you again, but I'm not really an expert in this field.
I get to this section:
"Bootloop troubleshooting: Bootloop occurs when a smartphone is not able to boot properly and stuck on Bootanimation and mainly caused by system files interfering with each others which cause instability and/or crash at the boot sequence. How to fix:
- Boot the device either into stock or custom recovery mode, wipe cache then reboot, if still, boot again in recovery and wipe data/factory reset then reboot. If not:
- Restore a nandroid backup with custom recovery if present. If not:
- Flash or reflash the official stock firmware. If not:
- Flash stock firmware with the appropriate pit file, after "pass", unplug usb cable, pull battery out for a minute, insert it, boot into recovery, wipe data and cache, reboot. "
I am already lost at the first stage...
