Question
I've encountered a bootloader loop issue after attempting to flash Tizen 3.0 firmware on my Samsung Z3 device (SM-Z300F model). The device displays "Could not do normal boot" and won't proceed further.
I can only access the PIT file from the device (contents available at https://pastebin.com/m9x6JLgj). I'm unsure what content should be flashed to the BOOT partition (U-boot, kernel, etc.) and would appreciate guidance on:
- Why this problem occurs
- How to retrieve more booting stage information
- Correct firmware flashing procedure
- Any potential recovery methods
Answer
Problem Understanding
The issue stems from flashing incompatible firmware (likely for TM1 or SM-Z300H models) on a Qualcomm-based SM-Z300F device. The bootloader loop indicates a firmware-device mismatch.
Solution Methods
-
Identify Correct Firmware:
- Confirm your device is SM-Z300F (Russian demo device)
- Search for leaked SM-Z300F firmware (e.g., AP_Z300FXXU1AOK9_usr.tar.md5)
-
Flash Using Odin:
- Use Windows PC with Odin tool
- Download correct SM-Z300F firmware package
- Flash all components (AP, BL, CP, CSC)
-
Alternative Recovery:
- If download mode works, attempt Heimdall or lthor
- For custom kernel, ensure it's built for Qualcomm chipset
Code Examples
No code examples available for this hardware-specific issue.
Additional Tips
- Source code for SM-Z300 series has been removed from Samsung's open source portal
- Commercial Z3 devices are no longer supported
- Be cautious with experimental firmware versions
- Consider device replacement if recovery fails
