The mobile repair & data recovery knowledge base
Fix smarter. Recover more.
Free, community-maintained, and continuously updated. PhoneRepair.biz consolidates scattered knowledge on phone data recovery and board-level repair — test points, EDL loaders, ISP pinouts, dead-boot procedures, and an honest look at what is and isn't recoverable.
Browse the knowledge base
- Data Recovery Fundamentals — Core concepts: logical vs physical recovery, device states (BFU/AFU), storage types, the recovery decision tree, and do-no-harm triage.
- Logical Recovery — Software-level extraction: ADB, iTunes/Finder backups, broken-device tools, deleted-file carving, app databases, and cloud-side recovery.
- Physical Recovery — Chip-level methods: ISP eMMC reading, JTAG, chip-off, programmers/adapters, dump repair and partition rebuilding.
- Boot Repair and Dead Devices — Dead-boot diagnosis and repair, firmware/boot region rewrite, and bringing dead devices to a recoverable state.
- Vendor and Mode-Specific Extraction — Qualcomm EDL/Firehose, MediaTek BROM, Apple DFU/checkm8, Samsung Download/Odin, Unisoc and more.
- Encrypted and Locked Devices — What is and isn't recoverable: Secure Enclave, Android FBE/FDE, FRP vs data, honest expectation-setting.
- Liquid and Physical Damage — Water/corrosion remediation, broken-screen extraction, cracked-board and shorted-board recovery workflows.
- Board-Level Repair — Micro-soldering, schematics/boardview (ZXW/WuXinji), common IC failures, repair-to-recover practices.
- Model and Chipset Reference — Per-model test-point/ISP/EDL/JTAG data, SoC and storage-IC references, known failure points.
- Tools and Equipment — Professional boxes, forensic tools, consumer software, and bench hardware — with honest capability limits.
- Legal Ethical and Business — Consent, proof of ownership, chain of custody, data handling, and shop business practices.
- Community and Learning — Glossary, learning paths, contribution guidelines, and curated external resources.
- iPhone Panic Logs and Boot Diagnostics — The iPhone 3-minute panic reboot loop, panic-full log decoding, a living panic-signature database, and per-model required-sensor faults (iPhone 11 and newer).

Featured: the iPhone 3-minute panic loop
The 3-minute panic reboot loop (boots, runs ~3 minutes, kernel-panics, repeats) plagues techs on iPhone 11 and newer. We maintain a living, model-by-model reference:
