[almamunsimul]

Hello Everyone,

I need help to calculate the 16-digit unlock code (NCK) for my SoyeaLink SRT873 router. I have already dumped the EFS and identified the V4 algorithm signature.

Device Details:

• Model: SoyeaLink SRT873
• Chipset: Qualcomm Snapdragon X55
• Algorithm: V4 (Verified from dump)
• EFS Offset: 1E61FD
• IMEI: 865881060370670
• Encrypted Hex (from offset 1E61FD): 08 8A 56 88 01 06 73 60 07 08 04 64 8D 00 00 00

Please help me to get the correct 16-digit code. Thank you in advance!
