When I try the MMI/USSD codes by calling *#06# or *#9900# I'm getting unknown application error or connection error. 

I tried it on another device and its just working fine.

Yet another problem related to network settings and device information.... Unbelievable.

Topic above shows what I'm trying todo aswell.

I cannot even debug this phone because of this, cannot enter recovery menu, cant change APN settings, 2 times I've send this phone in for repair.

What a joke.

And the unsolved cherry ontop of the pie. Not able to acces recovery menu to perform a full wipe.

And I'm also lost on how to obtain a PUK2 code for my FDN Settings. Apparently my mobile carrier cannot provide me a PUK2 because they only provide a PIN1 and PUK1 for the simcard and have no clue what the useage of PUK2 is.

Very strange. 1733673078086.jpg
