I need a well-structured, easy-to-follow tutorial that walks an average user through fixing an Android phone caught in a bootloop after a root or custom ROM flash. The device can still reach recovery mode, so the guide should start from that point and show every practical route back to a stable, booting system. What the tutorial must cover • Pre-repair preparation: data backup options, battery level, and how to install ADB / Fastboot on Windows, macOS, and Linux. • Recovery-based fixes: wiping cache, Dalvik, and performing a factory reset—explained clearly with screenshots or labeled photos. • Flashing stock or custom firmware safely: where to find the correct image, verifying checksum, and flashing commands step by step. • Post-repair checks: first boot precautions, re-locking the bootloader if desired, and tips to avoid another bootloop. Format & tone – Plain-language instructions, minimal jargon, and quick definitions when a term is unavoidable. – Visual aids embedded in the document (PNG or JPEG) plus a separate assets folder. – Final deliverable in both editable DOCX/ODT and a polished PDF ready for sharing. Acceptance criteria 1. I can reproduce each step on a test phone and reach a normal boot without extra help. 2. All commands and links work as written. 3. The guide reads smoothly in Indonesian (primary) with brief English technical terms kept where they are industry standard. If you have hands-on experience unbricking rooted Android devices, I’d love to see a short sample or description of a similar project you completed.
