First step:
We will use software free Joker v0343 or superior version available for unloading at the end of this manual. We used the cable series unlock compatible reference CA-A31 with the new models Siemens/Benq A31, AF51, X81, EL71, S68.

Second step:
We opened the telephone and we cut the track indicated in red in the superior image (it presses on the image to extend it). We will cut by where it is indicated crossed in red the track for being the site more surely. We already can mount the telephone again. We connected the telephone extinguished to the cable series and connected this a port COM1 of the PC. We selected in software AX72/75/C110. We selected in software USES OTP IMEI. We selected port COM1. We pressed RECALC ALL KEYS. We pressed power on button of the telephone seconds until software loaded boot. The process unlock will take a little with this software. We will hope to that the process finalizes, as is in the superior image. Although Joker is a shareware, even supports new flash ST of the A31 model.
