The problem is, as I said to z.and.some.other.random.chars
in the other thread, that Mini was released in September 6 2012. It's not clear which firmware started to be applied to Mini. It could be 2.0.0.c. 2.0.2 and 2.1.1 seems to be for Japan only. It could be 2.1.4, when devs started for a period to release different firmwares for Glo, Touch and Mini.
I'd try 2.1.4 for Mini, what do you think about?
