Even though it gives the message of the damage the RSA Unlock does to the first part of the flash-file in these phones, both phones can still reboot after detaching from Cruiser after this.

Any suggestions?

Thanks in advance.

1st updgrade your phones to CID52 , after you can unlock your phones without logs.

I've tried that, but I get the same "Error: Could not initialize GDFS access." message
