[Guide] How to Install TWRP Recovery on Samsung Galaxy J5 2015 LTE China Mobile (SM-J5008 / j5ltezm)​

• Device Model: Samsung Galaxy J5 (2015) China Mobile CMCC (SM-J5008 / j5ltezm)
• Chipset / Platform: Qualcomm Snapdragon 410 (MSM8916 - 64-bit Quad-Core ARM Cortex-A53)
• Storage Interface: eMMC 4.5
• Stock OS: Android 5.1.1 Lollipop / Android 6.0.1 Marshmallow
• Target Recovery: TeamWin Recovery Project (TWRP) Custom Recovery
• Status: 100% Tested & Verified Working

Prerequisites & Critical Warnings​

• C-Lock / CROM Service Unlock: The China Mobile variant (SM-J5008) contains Samsung's regional CROM bootloader restriction. You must run the Samsung CROM Service unlock utility before flashing; otherwise, Odin will reject the binary with CUSTOM BINARY BLOCKED BY C-LOCK or SECURE CHECK FAIL: RECOVERY.
• Knox Warranty Void: Flashing custom binaries permanently trips the hardware eFuse (0x1), disabling hardware-backed security features.
• FRP & OEM Lock: Ensure OEM Unlocking is enabled and remove any Google/Samsung accounts prior to flashing to avoid Custom Binary Blocked by FRP Lock.
• Data Backup: Back up important personal files, contacts, and photos before flashing.
• Required Files & Tools:
  
  • Odin3 (v3.10.7, v3.12.3, or v3.13.1 recommended).
  • Official Samsung Mobile USB Drivers installed on PC.
  • Verified twrp-j5ltezm-j5008.tar file.
  • Reliable Micro-USB data cable connected directly to a rear PC motherboard USB port.
  • CROM Service APK (if your bootloader status is not yet unlocked).
  • Magisk or SuperSU ZIP file to root and prevent the stock kernel from restoring the stock recovery image on boot.
