Sup guyz, i did be grateful if you could me out with the decoding of my modem. I have decoded a lot of modems bt this particular brand seems to be giving me a bit of difficulty. I have been able to obtain the old Algo and new Algo and also the flash code. But when i insert a new sim, it doesn't ask me for the unlock code. Mostly, the solution to this problem is to use a huawei code writer which would detect the port the modem is inserted in so that you can forcibly write the unlock code on the modem but the issue is when i ask the huawei code writer to detect the port, it gives me a blank space. The modem type is the vodafone huawei k4201 model. Your help would be much appreciated. Thanks in advance
