unlock failure on Huawei E220

i had an extra Huawei modem around so thought I would try unlocking it for fun.

Ubuntu 12.06 64bit lts.

dpkg -l |grep pytohon-serial ii python-serial 2.5-2.1build1 pyserial - module encapsulating access for

Thanks for the feedback. This is a known issue and is already mentioned in the README and with an explicit warning in the program. The E220 unlock code cannot be generated by the current algorithm.

I have some ideas on how these devices can be supported but cannot test them until I get hold of one. I'll leave this issue open until then.

@mcphail I realize this is incredibly old, but if I sent you one would you be interested in (or able) completing this milestone - E220 support?

I got error at unlocking with E156G. Then i tweaked script to allow me to change unlockCode for other algo version (there are 3) ... and for my surprise when i ran it again it saw that device was unlocked.

I tried to connect and it was really unlocked. So, let me ask a dumb question. Did you ran script twice?

About E220. This modem is one of the most popular models, it was always easy to unlock it so i can't really understand why is not working for you.

Regards.
