Factory reset to cure all problems?

[jamesdeen]

Hi,
Is there such a thing as a Factory reset? If so, would it basically fix all problems, restoring the phone to it's defaults?
I used the lokiwiz program to attempt to sim unlock my SPV M600, and although I was able to use another netwrok's sim card, I am not able to use my original sim card any more.
I'm hoping some kind of full reset can fix this?
Does anyone know how to fix my problem, or whether resetting the phone will fix it?
I tried holding the power button + pushing the reset pin, but that didn't fix it. As I understand, that was a only a 'hard reset'
Thanks for any help

** update **
I've since performed a a factory reset (camera+commMgr buttons+reset pin, followed by 'send' key) but it did not help.
Can anyone suggest how I can fix this problem to either fully unlock the phone to all sim cards including my original, or to revert it back to how it was?
Many thanks

To attack this from another direction, do you think that if I were to take it to one of these 'unlock your mobile for £20' places, that they'd effectively fix it by unlocking it properly?

This sounds strange. Though I can't be sure, I suspect the problem might be with your original SIM and not the phone.
I would try two things if possible before paying for any solution:
1) Try your original SIM in another phone.
2) Try another SIM from the same company as your original SIM in your phone.

At the very least you will know for sure where the problem is.

I considered not posting this because in doing so I would be revealing to the world the full extent to my ineptituder and stupidity.
But for the sake of others, cursed with a similar level of intelligence, here are my findings:

I did have two different phones, and two different sim cards.
After using lokiwix to unlock my M600 (which at the time had an Orange SIM in it), I inserted the other sim, entered the code, and it worked.
Then I put the Orange SIM back in, and it complained, and didn't work.
I then put my Orange SIM in the other (unlocked) phone, and that worked. Back in the M600, and it didn't.
To summarise : Either sim in the other phone worked, but only the other sim worked in the M600, not the original Orange SIM.

Ok, enough waffle.
I asked someone who knew what they were talking about and they said "The missing/incorrect SIM message is nothing to do with unlocking. Try checking the SIM contacts'
I doubted that it could be as simple as that because both SIMs were provably fine, as were both phones.
Nevertheless, I put the orange sim in the m600, and wiggled it a bit to ensure a good contact.
Low and behold, it worked.

Ok, so I feel pretty stupid now.
But if this is of any help to anyone else, then maybe it's worth it.
