I have a cf62 here software version22,can i downgrade the software to unlock it or do i have to use testpoint??
 
Hi,
it is verry simple. Download CF62 SWUP version 12 from:
http://www.allsiemens.com/flash/CF62-120101_eng.exe.htm (for english, german,french language), check the "Skip" box and downgrade to the version 12. After unlock, download from:
http://eh.student.utwente.nl/~landy/index.php?dir=CF62_CF6C/
user: mobile ; password: elibom
version 24 with your favorite language pack.
For unlock use the Freia or Joker software (for example)

Hello all,
-about the firmware downgrade, I tested now and post lather the steps.
-about the testpoint, download from: http://rapidshare.com/files/18403650/Siemens-Testpoint_Station_3.rar

You can not downgrade becouse of the new bootcore denies the older sw. Only solution to downgrade is via TP and that's why it's useless becouse unlock this version can be done via TP too.
 
thanks. unlocked it with tp. got "insert sim" error. i solved it. here is how i think what happened:
when cutting tp. instead cutting sideways. i cut it downwards. by cutting downwards when metal breaks. it breaks downwards. thus, the spilting metal touching the next layer metal and curse a short. thats how i got insert sim error. i cleaned the cut and make sure the 1st layer is not touching the 2nd layer. problem solved.
hope this helps.
