- BerryCloud or BB10.xyz (community mirror sites)
⚠️ Avoid random .exe files from untrusted sites – malware risk. Check file hashes if possible.
Troubleshooting common issues
- Device not detected: reinstall BlackBerry USB drivers; try a different USB port/cable; check Device Manager for unknown devices.
- Autoloader fails mid-flash: try redownloading the package (corruption), run as Administrator, or boot PC into Safe Mode to avoid driver conflicts.
- Stuck in boot loop after flash: try repeating the autoload; if persistent, there may be hardware issues.
- Error about non-matching model: ensure the autoloader is explicitly for SQC100-1 (CDMA vs GSM variants differ).
