Dear All,

During the recovery procedure I loaded a zImage found it in my PC to a different X3 modem after that I get Kernal Panic as follows.

Can you help to recover this X3 modem.

Many Thx

Dear Admin,

Thank you for your reply.

I have these files.

My issue is my Linux Kernal is corrupted I guess.

First I need to fix my Kernal, then I can use these documents.
