I dont know what is going on with AL21 phones

I have a normal USB to Serial SIemens Cable, I have used it for flashing, unliocking, downloading stuff, etc with amost every siemens phone with uses the standard siemens Connector.

I dont know what is going with a pair of AL21 phones, they just DONT connect to any application, no matter if it is a data application like SIMOCOC or a service application like joker the phionees are not visible

I disassembled the cable and assembled another via COM Port using pinout:

2 - gnd
3 - tx
4 - rx

no success
then jumped from 2 - gnd to 5
no success

but it works with other siemens like C72, A75, CX65

Can some one please tell me what has to be done ? I dont want to unlock the phoine, so, just dodnt talk at all about Cutting track, but if it helps, I already Cut track to one of them...

I need to know what to don only for the applications to see the phone, noo matter if it is for uploading a ring tone of for just Reading phone information with Joker Info Button.

Thanks in advance andd have a very Happy New year !!\
