Help me recover my NCK [Solved restoring PM120]

[ontopgsm]

Hi. Here is the deal. Long story short is like this: I have a Nokia 5230 rm-588 which used to be locked to Movistar Spain. I made all backup one can make except for full dump. The problem is that now the phone is locked back to Movistar. Cyclone box indeed displays the stored nck but the trouble is that it look exactly like this: #pw+8[g@56446710922+7#. I tried also with some other box that has this feature and also the second third and forth digits are displayed wrong. How can I recover the missing 3 digits because I don't wanna manually try all possibilities until I get it right. Thanks in advance.

just write back the PM120 back-up and restart the mobile: it will be unlocked again

I figured out something. At the very end of field 120 subfield 3 after all the zeros there is a string that represents the nck. In my case it's 07385B67403536343436373130393232. The first 07 might be the level (+7). The rest if you use a hexeditor gives you the nck "8[g@56446710922". In hex "5B" = "[" ; "67" = "g" ; "40" = "@" so this is where "[g@" comes from. I didn't try to write field 120 yet since the phone is still stuck in "Phone start-up failed. Contact the retailer" and also doesn't connect over FBUS and USB. I took a look at other backups from other phones and if the phone is unlocked with the code +1 the string is at the very beginning and if code +7 was used then it's at all the way at the end.

I blasted the phone with hot air and it works now. You are right, writing PM120 does unlock the phone so weird characters in stored NCK aren't an issue and who knows might be normal with SL3.
