Motorola C975 shows RS-232 Serial when powered using *# - GSM-Forum

technoguy · 08-02-2006, 00:34

Hi All

I am trying to unlock a Motorola C975, the bootloader version is 5 something but I always get Switching to P2K and then Cannot Connect.
The phone is from 3 Australia and I believe 3 have put some kind of restriction on the phone so that USB communication is disabled.

I powered the phone using *#, it shows me the boot loader version on the screen and the firmware version and below that it says RS-232 Serial.
Does this mean, I can only unlock the phone using serial RS-232 cable??

Please give your views and ideas on this.

Thanks

learn the basics, don´t trip. just plug usb cable before you put phone in boot mode, or use repair cable.

Thanks for suggestion, but thats what i am doing, trying to learn the basics. I have tried what you are saying but doesnt work, also which repair cable are you talking about and where can I get it from? Thanks

probably you have bad connection (cable problem). if u plug usb cable (pc and phone), and then put phone in boot mode, it accepts usb connection. when it not happen, it´s because phone is not properly attached to pc, which happens when u have a defective cable or dirty contacts.

repair cable is a normal usb cable, only that pins 13 and 14 are connected. when you have no keyboard to use, for instance, it´s the only way to put phone in boot mode.

@ technoguy

Try to Flash your phone good Original Flash with RDS Lite 2.7 or 2.9.

I think Pk2 by Zulea don't right for Flash your Motorola Phone, but RDS lite
( Original Motorola Sw) is perfect.

I think it is help you.
